Periodisering av fysträning under ett 52-veckors tennisår för elitspelare

Periodization of physical training during a 52-week tennis year for elite players

October 1, 2025

Elite tennis is a uniquely demanding sport, with a competitive season spanning virtually the entire calendar year. Unlike many other sports, there is no clear off-season with long periods of rest – top players on the ATP and WTA tours compete and travel almost year-round [1] . To meet these demands without suffering from overtraining, injuries or poor form, players and coaches apply periodization in physical training. Periodization involves dividing the year's training plan (macrocycle) into different phases or blocks with specific goals, and varying training content, intensity and volume in a systematic way [2] [3] Through smart periodization, the player can achieve continuous development, peak form at the right times and at the same time minimize the risk of overload and injury.

The basic idea behind periodization is based on the body's adaptation to training. When new or harder training stimuli are introduced, there is first a shock phase (alarm reaction) where the player may feel tired and performance temporarily decreases. This is followed by an adaptation phase where the body reacts positively – strength, speed, endurance or other qualities improve in response to the training. However, without sufficient recovery, one risks reaching a fatigue phase where progress stops and the risk of injury increases [4]. [5] . The purpose of periodization is to balance load and rest over time so that the body has time to supercompensate (build itself stronger after training) but never drives itself into overtraining syndrome. As veteran trainer Gabe Jaramillo put it: the periodization plan becomes like the player’s “GPS” – it shows the way to the goal and ensures that we don’t get lost along the way [6] [7] .

In this post, we look at how elite players structure their fitness training over a full 52-week tennis year. We cover the science behind periodization , describe the different training phases during the year – from pre-season build-up through the challenges of the competition period to post-season and active rest – and how key components such as strength, explosiveness, speed, mobility and recovery are integrated into each phase. We also connect this to microcycles , i.e. what a typical training week might look like, with concrete examples from the ATP and WTA tours. We also look at how training is adapted to the surface (gravel, hard court, grass) and what considerations are taken to improve movement patterns, injury prevention and muscle adaptation. Finally, quotes from coaches, experts and players are included, as well as current research findings on tennis fitness, recovery, overload and injuries.

Scientific basis: Why periodize tennis training?

Periodization has its roots in exercise physiology and sports science. At its core is planned variation – systematically changing training specificity, intensity, and volume over time to drive long-term performance and minimize injury [2] . In tennis, this is especially important as the sport combines explosive movements, sustained ball duels and repetitive movements (e.g. serve, forehand) over long seasons. Traditional linear periodization (where you go from low intensity/high volume to high intensity/low volume in clear blocks) is difficult to fully apply in tennis due to the long season and unpredictable competition schedule – you can’t always know when a player will be out of a tournament or how many matches will be played each week [8] Instead, non-linear or undulating periodization is often used, where the load is changed more frequently, and block periodization that is adjusted around competition blocks.

According to tennis researchers Satoshi Ochi and Mark Kovacs, a tennis-specific periodization model still requires mastering the basics of training planning for a year-long program [2] Their work emphasizes that periodization in tennis aims to optimize training effect over time without driving the player into a wall , given the sport's high training volumes and risk of overexertion [3] . Key principles include the principle of specificity (that training gradually becomes more competition-specific as the season/competition approaches) and progressive overload (that gradually increase the load as the body adapts, for continued development). At the same time, recovery must be planned in – both built-in rest days each week and easier weeks after tough periods. Without this variation, continuous high stress can lead to overtraining and injury, something that periodization aims to prevent [5] .

Research supports the value of periodized training for tennis players as well. For example, a study of college tennis players showed that periodized strength training with gradually increasing intensity produced significant improvements in strength and power [9]. A review article on tennis-related injuries found that elite male players report about 1.6 injuries per 1000 hours of training and female players about 1.0 per 1000 hours (the difference was not statistically significant) [10] . This highlights that both men and women are at significant risk of injury, and that a well-structured training plan is needed to stay injury-free. To quote former top tennis player (and now coach) Robin Söderling: “I was the perfect candidate for burnout, because I didn’t listen to my body at all.” [11] His experience with exhaustion shows the importance of having a plan that includes recovery and adjustments based on the body's signals.

In conclusion, the science gives us a clear direction – periodization is crucial in tennis. It involves structuring the year into a macrocycle (annual plan), divided into mesocycles (training blocks of usually 4–8 weeks with a certain focus) and microcycles (usually weekly plans) [7]. The next step is to put this into practice by defining the different phases during a 52-week tennis year and what the training looks like in each phase.

This year's training phases: Pre-season, competition period and post-season

An elite player's year can be roughly divided into a preparation period (pre-season) , a competition period (in-season) and a short transition/rest period after the season (post-season). Within the competition period there are also smaller competition blocks and possible intermediate periods for training. Here we go through each phase and how different training components are emphasized.

Pre-season – building strength, endurance and explosiveness

The pre-season is the longest training period and lays the foundation for upcoming competitions [12] . It usually occurs at the end of the year (e.g. November–December for many professionals) or early in the year before the competition schedule begins in earnest. During this phase, players have few or no tournaments, allowing them to focus more on off-court fitness and general training without having to peak their form. At the beginning of the pre-season, the emphasis is often on a general preparation phase with relatively high training volume and lower intensity – the aim is to build a broad base of endurance, strength endurance and basic strength [13] For example, this could include running, cardio, light weight training with more repetitions, and mobility and core stability exercises. For a younger or newer player, this basic training phase can be extra important to “get going” after rest.

After the initial general phase, one typically moves into a specific preparation phase , where training becomes more directed towards the demands of tennis [14] . Here the intensity increases and the exercises become more explosive and tennis-like: e.g. heavier strength training for legs and core (to build power in the legs for explosive changes of direction and a strong core for serve/hit), jumping and medicine ball training for explosiveness, sprinting and footwork exercises for speed, and agility training for changes of direction. Strength training during the pre-season is often periodized into its own phases: you can start with a hypertrophy/endurance phase of ~4–6 weeks, followed by a maximum strength phase and then a power/explosiveness phase closer to the competition season [15] According to an article on college tennis, after the off-season, players start with a 6-week endurance strength phase to accustom the body to loading and build basic strength, which then paves the way for heavier and more explosive lifts [15] [16] Exercises such as squats, lunges, deadlifts, bench presses, and chin-ups are common “base lifts” that work multiple muscle groups simultaneously and build functional strength for tennis [17] It is worth noting some gender differences – female players tend to place extra focus on hamstring and hip strength to increase knee stability [18] , as statistics show that they suffer from knee-related injuries more often than male players. In general, women have lower upper body strength than men, which motivates building strength in the shoulders/arms for serves and groundstrokes [19] [20] Men, on the other hand, may need to place greater emphasis on shoulder endurance as they serve harder and play best-of-five sets in Grand Slams, something we will return to.

Explosiveness and speed are gradually trained more during the preseason. Early on, you might work with basic stretching exercises and shorter sprints, while later in the preseason before competition, more sport-specific exercises come: for example, directional quick footwork drills, sprints with changes of direction, plyometric jump-like movements on the court, and explosive medicine ball throws (to develop rotational power similar to forehand/backhand). One physical trainer explains that the goal is to make the tennis player “more athletic and robust” so that explosive movements on the court become more effective [21] [22] To take a concrete example: if a player lacks power in their serve, preseason training may include extra focus on squats and leg strength, as better ground reaction force (power from the legs) can directly increase serve speed [23] . Throughout the build-up period, mobility training runs like a red thread – dynamic mobility (e.g. mobility exercises in the warm-up) prepares the body for the session, and final stretching/yoga helps maintain or increase mobility despite heavy training. Shoulders, hips and ankles in particular are important for tennis players to keep flexible and injury-free.

Another important component of the pre-season is recovery and injury rehab/prehab . Often players begin the off-season with an active rest of about two weeks immediately following the previous season. [24] This period is sometimes called the post-season or second transition period and involves resting from tennis and hard training, but continuing to engage in light alternative training. For example, players may cycle, swim, do light cardio, or do yoga during this time to heal minor injuries and mentally unwind. [25] [26] Studies show that an active rest period promotes muscle and tendon recovery after the many games of the season [26] . When the actual pre-season training starts after the rest, it is still important to periodize within this – i.e. not go full speed every day. Ochi & Kovacs recommend tennis players who train >16 hours/week to take at least two days completely without tennis training per week for recovery [27] [28] . Often this is done with a rest day (e.g. Sunday) and two half days off where perhaps one session is free or very light training [28] During hard training weeks, many people include massage, stretching sessions, foam rolling, ice baths, and more as “recovery sessions” to help the body recover [29] [30] .

Investing in a solid preseason pays off in the long run. Fitness expert Matt Kuzdub believes that players should set aside at least 8–12 weeks for an off-season training block where they focus extra on fitness (tennis training continues, of course, but with a lower priority) [31]. He points out that many players are reluctant to take a break from competition, but that a structured preseason combined with maintenance training throughout the year “will physically separate players from their competitors.” [32] An example of what a microcycle might look like during the preseason is given in the table below, based on principles from the USTA/ITPA and tour coaches:

Example: Pre-season training week (ATP player) – focus on strength and explosiveness (after general endurance period):

Day	Morning (tennis/gym)	Afternoon (tennis/gym)
Monday	Tennis: Technique and footwork (2 hours). Then flexibility (jumping exercises) 15 minutes.	Strength: Lower body heavy (leg strength: squats, lunges) + core strength. Finish: mobility/stretching.
Tuesday	Fitness: Intervals (e.g. 10x200 m run) + agility drills on the track (15 min).	Tennis: Points-play exercises 60 min (match-like ball duels). Strength: Upper body light (dumbbells/rotator cuff, arm strength high reps).
Wednesday	Recovery: Easy jog 20 min or bike. Mobility training and massage. (No tennis this morning)	Tennis: Tactically focused training 90 min (sparring with focus on hitting patterns). Plyometric training 15 min (quick side steps, box jumps).
Thursday	Tennis: Intensive drills 90 min (ball machine or feeder, high intensity).	Strength: Lower body light + explosiveness (e.g. jumping series, lighter weight at maximum speed). Core training (plank, medicine ball rotation).
Friday	Fitness: Medium-distance running 30–40 min (endurance). Then tennis: serve and return dice 60 min.	Strength: Upper body heavy (bench press, chins, shoulder press – few reps high weight). Finish: stretch/yoga for recovery.
Saturday	Tennis: Match play/training match, 2–3 sets to practice competition moves.	Half rest day: Light recovery (swimming or walking). No heavy training.
Sunday	Rest day: No tennis or physical training – only rest and possible active recovery (e.g. yoga).	–

Table 1: A typical week during the latter part of the pre-season. Note the mix of physical training (strength, conditioning, explosiveness) and tennis training, as well as recovery days. According to the recommendation, about 2 days/week should be tennis-free to allow the body to recover and prevent injuries [33] [28] .

During such a build-up week, the player spends a lot of time in the gym and physical development, while continuing to practice tennis to hone technique and maintain ball control. The focus is on building “reserve capacity” – more strength, speed and endurance than may be needed immediately, so that you have a margin during the season and a more resilient body.

Competition period – performance maintenance, peak performance and week-by-week adaptation

When the competition season begins, the nature of the training plan changes. Now it is a matter of maintaining the physique that has been built up, getting in top shape for important tournaments and at the same time managing a busy schedule of matches, travel and different surfaces. As mentioned, the tennis competition year is long – from the Australian Open in January through the spring clay tour, the summer grass, the autumn indoor/hardcourt until the ATP/WTA finals in November. Most elite players plan selected periods to be in top shape, e.g. before Grand Slam tournaments, and insert recovery weeks or training blocks in between to recharge [34] [35] Unlike many team sports with a final sprint to the season, tennis has multiple peaks – a professional player can aim to peak on perhaps 4–5 occasions during the year (e.g. at the four GS tournaments) [34] The periodization plan must therefore be flexible and individualized around the player's competition schedule.

During the competition period, one can roughly speak of two alternating phases: maintenance phase and peaking phase . In the maintenance phase – i.e. during the weeks when the player either does not have a major tournament or is between tournaments – the training intensity and volume are kept at a moderate level to maintain strength and fitness without reducing the quality of the tennis game [36] . Tennis (match training, technique, tactical drills) are often prioritized during these weeks, while physical training is adjusted around the match schedule. A rule of thumb is not to do extremely heavy/tired leg workouts just before important matches, but still get enough stimuli. Undulating training is common; players can, for example, do a slightly heavier gym session early in the week if they have a few days until the next match, followed by lighter explosive training or just activation closer to match day [37] . Research on periodization in tennis shows that it is possible to maintain and even increase certain physical qualities during the season through smart planning – for example, Kraemer et al. have documented that female college players who continued with varied strength training during the season maintained their strength better than those who stopped completely during the competitive period [38] . Many top players “top-up” their physiques even during tournaments: it is not uncommon to see them in the gym at the tournament facility after their matches to do a few sets of explosive lifts or maintenance strength. As fitness trainer Kuzdub notes: “many players lift weights, sprint and train explosively during tournament weeks – these are precisely the qualities that are easily lost if you only play matches” [37] .

The peaking phase occurs just before and during a target competition. This involves tapering , i.e. reducing the training volume to be rested, but maintaining high intensity at selected points to avoid losing sharpness and speed [39] . Typically, 1–2 weeks before a Grand Slam, the player can reduce the amount of physical training and total training time by perhaps 40–50%, focus on explosiveness, speed exercises and quality on the court, and give the body extra rest. A well-planned topping-up means that the player enters the tournament fresh both physically and mentally, with full power in the legs and high intensity in the body [39] . During the competition itself, recovery and lighter activation are key: between matches, you fill in with light jogging, stretching, massage and maybe a short tennis practice for timing, but nothing that tires you out. The goal is to keep the player in a state of “ready but rested”. As an example, Novak Djokovic’s team has described how his training load is greatly reduced the week before a Grand Slam, focusing on mobility, explosive footwork and mental preparation, while Rafael Nadal is known to tone down his gym training during the grass season to save his knees and instead focus on court training. There are individual variations, but the principle of peaking through reduced training volume and maintained intensity is common.

A critical challenge during the competitive year is to avoid overload and injury despite a demanding schedule. Both the ATP and WTA tours have guidelines for this. For example, the WTA recommends that players not compete for more than three consecutive weeks without a break, to allow time for recovery and training. [40] . Scheduling regular rest weeks or training/block weeks interspersed throughout the competition calendar is important. Data from elite tennis also show that the risk of injury increases significantly if players do not get sufficient rest: one study reported that the risk of injury forcing a player to withdraw doubled after playing four matches in a single tournament [41] . It highlights how stress accumulates during intense blocks of competition. That's why you often see top players drop out of less important tournaments if they've gone far in several events in a row – rather than risk an injury due to exhaustion.

The training content during the season focuses on quality over quantity . Strength training is maintained but with lower volume. A common approach is to do 2 strength sessions per week during the competition period (divided into upper/lower body or full body sessions) with a focus on explosive strength and power, instead of heavy lifting to exhaustion. Mobility and prehab exercises (e.g. shoulder rotations, ankle balance exercises, core stability) are integrated into the daily routine to counteract the wear and tear from repetitive strokes. Speed training can be maintained through short sprint exercises or reaction exercises at the beginning of training sessions on the court, a couple of times a week. At the same time, fitness often gets its due through the matches themselves and tennis sessions – if necessary, extra interval sessions can be added during longer competition breaks to maintain endurance. But generally, as one coach put it, “how can a player be poorly trained in terms of fitness if he plays and trains tennis for several hours every day?” [42] – tennis itself provides a lot of cardio training, so during the season it is usually more important to focus on strength/explosiveness and let the matches keep you going.

Recovery is key during the competition period. Players travel with physical trainers or physiotherapists who ensure routine treatments are carried out: post-match stretching, massage, cold/heat therapy, compression, nutritional recovery, etc. Small details can make a difference when it comes to performing “day in, day out” on tour [43] As the International Tennis Federation (ITF) points out, this refers to “recovery measures that are routinely implemented” – this can range from rapid recovery nutrition (protein/carbohydrate intake immediately after a match) to sleep strategies, ice baths and active rest [43]. . Each player learns what works best for them. Caroline Garcia, a top player on the WTA Tour, described her approach this way: “If I lose early in a tournament, I can train hard and improve what I need to. But once the tournament is underway, it’s just a matter of recovering for the next day.” [44] Her quote captures the balance: train when the opportunity arises (e.g. after an early exit), but prioritize recovery in the midst of competition.

Finally, here is a microcycle example to give. A training week for a player during the competitive season will of course look different than during the pre-season. Below is an outline of a weekly plan for a WTA player between competitions (when she is not playing a tournament that week), where the focus is on maintenance and specific improvements:

Example: Microcycle during competition break (WTA player) – week without tournament, with moderate training load:

Day	Morning	Afternoon
Monday	Tennis: Baseline game drills 90 min (focus on stroke consistency).	Strength: Full body workout medium intensity (Olympic lifts with light weight for explosiveness, 3×5 reps; spring jumps). Mobility training 15 min.
Tuesday	Tennis: Offensive play + net exercises 60 min. Speed: short sprints 10×10 m.	Tennis: Serve + return training 60 min. Recovery: Stretching and massage.
Wednesday	Rest day tennis: Easy bike 30 min for circulation.	Strength: Only prehab/rehab exercises (shoulder rotations, core, balance training). No heavy loads.
Thursday	Tennis: Points game with fellow players, 2 hours (match-like training).	Half-day rest: Focus on recovery (ice bath, rest). Possibly a short walk.
Friday	Fitness: Intervals 5×4 min (with the aim of maintaining VO2max) or fartlek running.	Tennis: Technique focus 60 min (fine-tune details). Strength: Explosive circuit training 30 min (medicine ball throws, jumps, kettlebell swings).
Saturday	Tennis: Calm training 45 minutes or sparring with lower intensity (maintain feeling).	Recovery: Yoga or Pilates 1 hour for flexibility and mental relaxation.
Sunday	Rest day: – (travel day if next tournament requires travel)	–

Table 2: Example week for a player who is not competing this week. This combines tennis sessions (to improve specific tactical aspects) with lighter strength/speed training to maintain fitness. Two rest days from tennis (Wed & Sun) give the body a chance to recharge for the upcoming competition block [33] During an actual competition week, the schedule would look different, depending on match days – then recovery and match preparation are prioritized over heavy training sessions.

As can be seen, the workload is lower than during the pre-season, with more elements of rest and recovery. But the player still keeps all the relevant qualities going: tennis skill, explosiveness, fitness and strength, albeit in smaller doses. This prevents her from losing too much between tournaments – something that research has warned about, as it has been shown that players can lose some physical capacity during longer breaks from competition if they do not train properly [45]. [38] By “topping up” her form during training weeks, she can be better prepared when the next tournament begins.

Post-season – active rest and restart

Sooner or later, the season comes to an end. After the last tournament (often at the end of the year, e.g. the ATP Finals or Next Gen Finals for men, and the WTA Finals for women, or for juniors perhaps the Junior World Championships), players enter a second transition period , or post-season. This period is usually 2–4 weeks long and is intended to give both body and mind a chance to fully recover before the next year's training cycle begins. [46] [47] . During the post-season, many players take a vacation** from tennis: they put away their racket for a few weeks and engage in other activities. Ochi & Kovacs describe that during this active rest, “almost no to very minimal tennis” occurs, and instead players engage in alternative training or other sports [48] For example, a player might do light cardio like cycling, swimming, play a little soccer or paddle for fun, or just do some rehabilitative exercises. The aim is to both heal any overuse injuries and give themselves a mental break. [47] [49] . It is not uncommon for players to treat ailments they have suffered during this phase – perhaps rehab training for a sore shoulder or forearm (tennis elbow), or physical therapy for knees and back. The post-season is also a good time for medical examinations, fitness tests and evaluation of the past season.

An important thing that happens in the post-season is planning : coaches and players evaluate the year and set goals for the next. This is when the periodization plan is adjusted, perhaps with input from testing. Experts recommend conducting fitness tests 2–4 times a year – preferably at the end of one phase or the beginning of the next – to see the player’s development and needs. [50] [51] . For example, a player’s agility, speed, strength and endurance can be tested after the season to compare with the baseline from the pre-season. The results then determine what needs to be focused on during the upcoming pre-season. In the case of young players, the growth curve (height, weight) can also be followed, since biological development greatly influences training regimens [52] [53] All this information is used to tailor the next year’s plan – the accrual plan is “live” and constantly updated, as Jaramillo noted [54] .

After a few weeks of total or active rest, the cycle begins again: a new pre-season begins, often with low intensity at first (an adaptation phase where the body gradually gets used to training again) [55] [56] . The player may start with light running and gym work, then increase after a couple of weeks. It is worth noting that today's top players generally make better use of the post-season than a few decades ago – there is greater awareness of the role of recovery in long careers. For example, Roger Federer and Serena Williams have often stressed the importance of “resting the body, so that the hunger and joy are still there for the next season” during their long careers. A study of youth players in Sweden (the SMASH study) confirmed this: those who made sudden large increases in training volume suffered significantly more injuries [57] [58] The researchers recommended a rule of thumb of increasing training volume by no more than ~10% per year for young players, emphasizing that “the challenge is to gradually build up to high training volumes, not to immediately train at high volumes” [59] In other words, patience and long-term planning win out over shockingly increasing training – which also applies to established pros in the post-season.

Surface adaptation: training for clay, hardcourt and grass

Tennis is played on several different surfaces, mainly clay, hardcourt and grass, which places slightly different physical demands on the players. The clay season (e.g. the European spring with the French Open as the highlight) is characterized by slower courts with higher bounces. Ball duels are longer and players often slip into shots on the clay. Hardcourt is a medium-fast surface with relatively predictable bounce, while grass (e.g. the short grass season around Wimbledon) is much faster and low-bounce, where the points are shorter and the players need to react lightning fast. Elite players adapt their training before and during each surface period to optimize their game and prevent injuries related to the surface.

On clay , the emphasis is on endurance and footwork . Training for the clay season often includes extra conditioning – players need to be able to handle long ball duels in high heat. Mark Kovacs (physiologist) has pointed out that a clay tournament like the French Open can mean a player running several kilometers per match on the heavy surface, which requires top fitness and muscular endurance in the legs. Therefore, many include more interval training and leg endurance exercises before the clay season [60] . At the same time, slide technique is practiced: sliding sideways on gravel requires strong legs (especially thighs and hip adductors) and good balance. Training routines include specific exercises to improve sliding, such as shuffles and lunges in sand or on gravel to simulate the surface [60] . Players also focus on precision and patience in the game during training – on gravel you often need to hit many balls to win the point, so mental endurance is trained through long rally exercises. Purely physical injury profile on gravel: the surface is softer for the joints (less impact than hard court), so acute ligament injuries are somewhat less common, but muscle overload (e.g. groin, hips) can occur if you are not used to sliding. The advantage is that gravel provides a slightly more “forgiving” load on the knees and ankles thanks to the sliding and the failure of the surface.

Examples of training for clay court preparation could be longer sessions on the court at a lap-resistant speed – e.g. a drill where the player receives a ball every 5–6 seconds for 5 minutes at a time, to simulate a long point or tiebreak. Mobility training is also central, as the higher bounce of the clay court forces players to sometimes hit balls at shoulder height; good shoulder and thoracic spine mobility helps in those situations. One study noted that clay court players often have fewer knee problems but have to watch out for their back and shoulders due to the many topspin shots above shoulder height. Therefore, back prehab (e.g. rotation training, core strength) is integrated into clay court training.

Hardcourt, the most common surface on tour, requires an all-round physique . The nature of the surface (hard concrete/asphalt with a thin synthetic surface) means that the ball bounces quickly but predictably . Players need explosiveness for quick starts, but also strength to brake and change direction without slipping (as they do on clay). Strength training for the lower body is especially important for the hardcourt season – strong quadriceps, hamstrings and calves act as “shock absorbers” for the knees and ankles during hard braking [61] Training programs for hardcourts often include plyometric training (jumps, bounces) to both increase explosiveness and strengthen tendons/joints against impacts [62] . Mark Kovacs recommends, for example, deep jumps and quick lateral jumps to accustom the body to changes in direction on hard surfaces. At the same time, players do speed drills – ladders, short directional sprints – to cope with the high tempo [63] . Hardcourt also places a higher overall strain on the body over time; studies have shown that players report more overuse injuries during long hardcourt swings. That's why coaches emphasize recovery a lot during these periods: ice baths and physiotherapy after matches are standard at, for example, the US Open Series during the hot summer. In terms of training, small adjustments are made during the season: if a player is going into an intensive hardcourt period with many tournaments (e.g. the summer's North American swing), they may reduce the running volume on asphalt during training to save their legs and instead do more cycling/pool training for fitness.

In terms of injuries, on hard courts, you often see more knee and ankle injuries due to the non-slip surface and higher impact load. As a preventive measure, you train a lot of proprioception (balance and control in the ankles/knees) as well as hip and core strength to relieve the pressure on the knee joints. Shoulders can also take a beating, as the surface favors aggressive play and many serve/smash attempts on high-bouncing balls; consequently, rotator cuff strength and shoulder blade control are included in physical training continuously.

Grass , the fastest and most specialized surface, requires quick reactions and a low center of gravity . The ball skids and bounces low on grass, requiring players to bend their knees and have strong core and legs to land shots. In preparation for the grass season, many players add extra flexibility and mobility training to their knees and hips so they can land their groundstrokes properly. [64] . There is also an increase in footwork with large strides – since there is not time to take many small steps on the fast courts, one practices explosively throwing oneself towards the ball in a few steps. Typical exercises are short sprints of 5–10 meters from a standing position, and ladder exercises focusing on foot placement and coordination [64] . Agility drills for grass can involve starting and stopping on slippery surfaces (some people practice in socks on hardwood floors or on wet grass to get used to the risk of slipping). Balance and strength in the ankles/knees are critical, as the grass can be slippery – many injuries on grass are muscle strains or sprains when the footing gives way. To prevent this, players work on eccentric strength for the hamstrings (reducing the risk of tears from quick jerks) and a lot of core/hip stability to keep the body stable in awkward positions.

The training content is also tactically adapted: as serving and volleying are favoured on grass, explosive upper body strength and serve speed may be something to work on extra before Wimbledon. Players may focus more on shoulder strength, serve flexibility (e.g. deep squats with jumps to mimic the push-off of the serve) and reflex volley exercises in training. An example is standing close to the net and having smashes/volleys thrown towards them reflexively return – this improves reaction ability. The physical part may include short sprints interspersed with rest, to mimic the short intense rallies on grass [65] . One coach describes that on grass “quick, aggressive footwork is required. Players take larger and faster steps to reach the ball and maintain balance on low shots.” [66] . Plyometric exercises that focus on fast power* are also common, e.g. box jumps for explosiveness. At the same time, recovery must not be forgotten : grass games put a high load on the back and thighs (due to the low position) and more muscle strains are often seen on green grass [64] Therefore, coaches ensure that players have sufficient rest between matches and training sessions on grass, perhaps more than on other surfaces [64] . An experienced physiotherapist on the tour said that during the grass season they try to “build in extra recovery days to avoid hamstring strains and back problems, which are common on grass” .

In summary: clay requires endurance and slide strength , hardcourt requires explosive strength and resistance to impacts , grass requires reaction speed and low position . Elite players periodize their training taking these differences into account. For example, a player who knows that he is weaker on grass might include a training block with extra focus on speed and volley training before the grass season starts. Similarly, a clay specialist may need to work more on explosiveness before hardcourt tournaments. Surface-specific training is one reason why you see players with different physical profiles dominate on different surfaces – for example, many Spanish and South American clay players are known for their endurance and leg strength (brought about by hard pre-seasons and many hours on clay), while players raised on hardcourt often develop faster play and more explosive training early.

Injury prevention, recovery and overuse: research and quotes

Tennis may be individual, but one thing all players share: the battle against injuries and fatigue. Over the course of a season, it is inevitable that the body will take a beating – it is important to mitigate this as much as possible with the training plan. Recovery is already something we have emphasized in each part, but to further clarify: top players treat recovery as an active part of the training program , not as passive rest. This can mean that recovery sessions are planned in just like training sessions. Small daily routines, the so-called “one percenters” (an expression for those small details that can give 1% better recovery), become habits – e.g. foam rolling every night, compression pants on the flight between tournaments, nutritional drink within 30 minutes after a match, consistent 8-9 hours of sleep, meditation for mental recovery, etc. [43] These habits are often personal. Novak Djokovic, for example, has spoken extensively about the importance of stretching and mindfulness in his daily routine, while Andy Murray has been known for his rigorous ice-bath discipline after matches.

Overuse injuries account for a large proportion of all injuries in tennis. A review in the British Journal of Sports Medicine found that over 52% of injuries on the professional tour are overuse injuries (gradually occurring), while 48% are acute traumatic injuries [67]. . Common overuse injuries include: shoulder injuries (e.g. rotator cuff tear, impingement) from serving, elbow problems (tennis elbow), wrist injuries, lower back pain, and knee problems (patellar tendonitis). “When it comes to shoulder injuries, it’s about building up as much as necessary to serve harder and faster – we are relatively weak in the shoulder area and need to get stronger there,” says tennis researcher Fredrik Johansson [68] . This quote emphasizes that many overuse problems (such as the shoulders) can be prevented by targeted physical training – in this case, strengthening the shoulder muscles to withstand the strain of serving. Periodization helps here by ensuring that there is time allocated for prehab in the training plan. For example, a mesocycle during the preseason might have a specific focus on shoulder strength and mobility. During the season, microcycles might include 2-3 short prehab sessions for shoulders and wrists each week.

A key concept is also load management – avoiding drastic changes in training or match load. The SMASH study in Sweden, which followed 301 juniors for 52 weeks, found clear associations between sudden increases in training and injuries [57] “It is when you train high volume one week and then low volume the following week that injuries can occur – the body does not have time to adapt,” explains Johansson [69] [58] . The solution is to increase gradually and in a planned manner – something that periodization is fundamentally about. Studies on high school sports students support this: a large report showed that many injuries in the transition to elite level are due to training volume increasing too much and too quickly [70] . The recommendation is clear: rather continuity and moderate increases than jerky large increases. A good training plan ensures that “the challenge is to get to high volumes, not to train high volumes right away” [70] .

To illustrate how top players actively work on injury prevention, we can mention some concrete routines: Rafael Nadal does extensive warm-up exercises for his knees and feet (elastic bands, balance board) daily to protect his chronically exposed knee joints. Roger Federer was known for skipping certain tournaments (e.g. the entire 2017 clay court season) to spare his body and extend his career – an extreme example of macro-periodization towards the end of his career. Serena Williams and others on the WTA have emphasized listening to the body: “Some days I play rock hard, other days I back off immediately if something feels wrong,” said a WTA player recently in an interview about training plans. Robin Söderling’s earlier quote about not listening to his body and getting burned out is a lesson: recovery is just as important as the training itself. This shift in mentality has also reached coaching – modern coaches closely monitor player wellness via questionnaires (RPE, fatigue estimates) and physical data (e.g. heart rate variability) to adjust training load in real time. Should a player show signs of overfatigue, the coach can ease training that week (so-called unloading week or recovery week, often scheduled every 4 weeks in a 3:1 scheme [71] [72] ).

Finally, let’s not forget about mental recovery . A 52-week tennis year is not only physically challenging but also mentally demanding. Periodization therefore in practice also includes mental breaks. The post-season is a given example where the player can disconnect from the stress of competition completely for a period. But even during the year, you might plan an “active rest” week where the focus is on joy and play: playing doubles for fun, trying a new form of training, or just training at home with family and friends around you to recharge your mental batteries. The legendary coach Nick Bollettieri used to say that “a healthy and motivated player beats a depleted talented player any day of the week” . There is a lot to it – optimal performance requires a fit body and mind.

Conclusion

Periodization of physical training is a must for today’s elite tennis players who want to stay at their best throughout a long tennis year. By dividing the year into clear phases – pre-season core training, competition-season fine-tuning and peaking, and post-season active rest – players can address all the important physical components: strength is built and maintained, explosiveness and speed are developed and adapted to the terrain, mobility is maintained for optimal technique, and recovery is integrated to avoid overload. Scientific principles such as General Adaptation Syndrome and training specificity provide the framework, while practice cases and tour experiences fill in the details. We have seen how both men and women benefit from periodization – despite some physiological differences (e.g. muscle mass, injury patterns), the basics are the same, with adaptations where needed (women’s hamstring focus for knee protection, men’s extra endurance for 5-setters, etc.).

However, a well-periodized plan is not a static document – it is dynamic . During the year, it is important to adjust to reality: perhaps an injury arises that requires changes, perhaps the player goes further than expected in a tournament (three extra matches played = more rest needed afterwards), or perhaps the tests show that a certain quality goal has been achieved earlier than planned (then the focus can be shifted). Successful periodization therefore requires continuous follow-up and communication within the team [73] [74] . The player, tennis coach and fitness trainer must be in sync. An ATP coach expressed the importance of this: “Communication is key – we adjust the training plan every week based on how the player is feeling physically and mentally.”

By following the principles of periodization, players like Novak Djokovic and Rafael Nadal have been able to dominate for over a decade, while young stars can avoid some of the “typical” traps that juniors used to fall into (like burnout at 20). It’s basically common sense backed by science: balance between training and rest, variation over time, and focusing on the right thing at the right time .

For you as an advanced player or coach, this means always having a plan for the year. Set your main goals (tournaments), plan your training blocks, and don’t be afraid to periodize even the smallest details – even a 7-day microcycle should have hard and easy days, just like we showed above. Prioritize your recovery as highly as your heaviest workout. As multiple Grand Slam champion Serena Williams once said: “A champion is defined not by her wins, but by how she recovers from a fall.” In the world of tennis, with its eternal cycle of new tournaments, greatness lies in being able to get up, recharge, and come back stronger – year after year.

Among others, Ochi & Kovacs (USTA) have described tennis-specific periodization and recovery theory [2] [3] , J. Reid et al. (ITF) analyzed periodization at the professional level [40] [38] , and the Swedish SMASH study has provided insights into injury frequency linked to training load [57] [59] Official statements and recommendations from the WTA and training manuals (e.g., NSCA Journal for tennis) have guided the description of training phases and content.

Quotes from players such as Caroline Garcia and Robin Söderling as well as coaches are included to give practical color to the principles [44] [11] Together, these sources paint a picture of what modern elite tennis training looks like – a picture of constant improvement, planning and adaptation in pursuit of the next victory.
