Effects of a 5-Week Linear Periodization Program on Maximal Strength and Speed on Elite Squash Players ()
1. Introduction
Squash is an extremely challenging competitive sport that requires an enormous level of physical fitness to compete on an elite level. Repetitive short explosive movements with split second responses and decisions to compensate for high ball travel speeds recording up to 281.6 km/h require high efficiency in agility, speed and reaction time pertaining to skill related fitness components. In squash, the ability to perform rapid acceleration and deceleration over short distances is essential for success where power plays an important role. Power is defined as the rate at which work is done or energy is transferred to perform a task (van der Kruk, van der Helm, Veeger, & Schwab, 2018) or the ability to exert maximal force in a short period of time. Research has shown that maximal strength is a major factor influencing performance and stronger athletes are found at higher levels of competition in a variety of sports compared with weaker athletes (Haff & Nimphius, 2012).
Participation in squash requires high competency in a variety of parameters such as muscular endurance, aerobic and anaerobic capacities, strength, power, speed, and agility (Bennie & Hrysomallis, 2005). Heart rates are often at an average of 190bpm spiking above thresholds of 80% - 85% of the players predicted maximum heart rate (Docherty, 1982) due to the intensive nature of the sport that can come up to rallies lasting 45 s - 60 s with very short breaks in between. Players may cover up to 5000 meters in a single 5 set match of squash lasting anywhere between 60 to 90 minutes requiring excellent cardiovascular endurance.
Literature concerning methods of training interventions to reach an elite level of physical fitness for squash is minimal. Typically, in a linear periodization, different training phases last approximately 4 - 6 weeks generally showing a steady progression with increasing intensities and decreasing volumes (Fleck, 2011). In this case study, the subjects consisted of high-performance elite athletes with different neuromuscular adaptations requiring variation from typical training methods. To ensure progress is made over a long period of time, some type of periodization or program variation is required (Kraemer, Duncan, & Volek, 1998). The limitations of standard traditional periodization raise hurdles to further progress (Issurin, 2010). In recent times, more alternative approaches in training design have appeared with little scientific deliberation.
In more highly trained athletes, strength gains are not achieved with low volume single-set training programs (Willoughby, 1993) therefore our program sees an increase in both volume and intensity over time. The cross-sectional area and percentage of fibre types within a muscle will vary significantly among elite athletes. The possibility exists to modify the characteristics of skeletal muscle if the stimulus presented is sufficient (Kraemer, Duncan, & Volek, 1998). This article aims to highlight the benefits of a 5-week linear strength and conditioning program to help improve strength and speed in elite squash players.
2. Methodology
3 male and 2 female elite squash players were subjected to a 5-week linear periodization program in preparation for the 2019 South East Asian Games. During the training program the athletes were subjected to maximal strength tests, muscular endurance tests and maximal speed tests. The athletes were guided into performing a 1-repetition max (RM) half squat test, 1-minute push up test, 1RM single leg adductor test, 1-minute sit up test and a 20-meter Sprint test.
Before beginning any tests, the athletes were given 30 minutes to warm up. The warm-up phase included light cardio on a treadmill or stationary bike followed by dynamic stretches and mobility to ensure the athletes were adequately prepared.
Table 1 breaks down how each athlete was given 3 - 5 sets in order to determine the athlete’s 1RM. The athlete was then given 2 - 3 attempts in order to determine the athlete’s 1RM. Table 2 describes the fitness components targeted and description of some examples of exercises given based off the list in Table 1.
· Half Squat Test (HST)
Athletes were instructed to stand, hip width apart, behind the barbell. When cued, the athletes picked up the barbell, standing tall in the squat rack. The weight of the barbell started at 80% of the 1RM of each athlete from a previous test conducted the year before. The athletes were then instructed to do a half squat. The weights were gradually increased every set until 1RM was achieved.

· Single Leg Adductor test:
The athletes were instructed to lie on the side which is being tested. The untested leg is then flexed to 90˚ at the hip and knee joint while the ankle is maintained in a neutral position. The tested leg is kept straight with 0˚ hip and knee flexion. Ankle weights were placed around the malleolus of the tested leg. The athlete was then instructed to lift the leg vertically upwards (adduction in side-lying) by trying to overcome the resistance of the ankle weights while maintaining the ankle in a neutral position. The weights were gradually increased. The process was performed on both legs.
· 1 Minute Push-up Test (PUT)
The test began with the athlete in a push-up position, hands placed shoulder width apart with elbows in full extension. The athlete was asked to maintain a neutral spine throughout the movement. A 4-inch block was positioned directly below the athletes’ chests to standardize push up depth every time. 1 repetition was counted when the athlete performs a push up and the chest comes into contact with the block and then returning to the starting position. Each athlete was given 1 minute to perform a maximum number of repetitions.
· 1 Minute Sit-up Test (SUT)
The athlete began in a supine position with both knees flexed to 90˚, feet on the ground. The athlete was instructed to sit up and reach to a marker that has been measured to 20 cm from the fingertips and directly above the knees. A repetition is counted when the athlete performs a sit up, makes contact with the markers and then the head returns to the starting position on the floor.
· 5 m, 10 m, 15 m and 20 m Sprint Test
For this test, a wireless timing gate system (Swift Performance Timing Gate) was set up on a 50 meter length track. The timing gates where set up at 5 m, 10 , 15 m and 20 m intervals. A finish line was placed at the 25-meter mark and all athletes were advised to not slow down until they reach the 25 m mark to ensure the results are not compromised by early deceleration.
Each athlete begins less than 1 foot away from the first-time gate and were instructed to start sprinting when ready. Each athlete was given a total of 5 attempts with 3 minutes break between each sprint. The best possible time for 5 m, 10 m, 15 m and 20 m were recorded for each athlete and displayed in TableA3.
3. Training Program Outline
A 5-week training program was designed to help improve overall strength, acceleration, and explosive power in squash players. During the 5-week training program, the athletes underwent a total of 12 special strength sessions, 4 hypertrophy sessions, and 3 speed and plyometric sessions.
· Sport Specific Injury Prevention Training (SSIPT)
SSIPT can be defined as the concept of applying sport specific exercises to help develop specific strength and reduce injury to carry out a specific task or sport.
Data captured from a case study following the UCS Swedish Open 2018 utilizing the Motrack system “captured players covering distances upwards of 1 kilometre per single game, with matches played in a best-of-five-game format, comprising hundreds of changes in direction and multiple complex movements, with player heart rates regularly registering upwards of 190 bpm—at times almost hitting 200 bpm” (“Data Highlights Squash’s True Physical Demands|Professional Squash Association”, 2021).
The SSIPT exercises chosen are specifically designed to mimic various aspects of squash which includes lunges, backward movements, rapid acceleration & deceleration, explosive power, functional core stability and aerobic endurance. Each session included 13 various exercises targeting joint stability, movement patterns, core stability and basic explosive power.
· Week 1 & 2 Summary
The athletes underwent a total of 6 Special Strength Training (SST) sessions for the first 2 weeks which was intended on improving sport specific movements. Each session included 12 various exercises targeting joint stability, movement patterns, core stability and basic explosive power. The athletes also underwent 2 strength sessions only utilizing a medicine ball. The medicine ball sessions included a total of 150 throws divided into various movements (wall slams, overhead throws, floor slams, etc.).
· Weeks 3, 4 & 5 Summary
During the 3rd, 4th and 5th week of the training program the athletes underwent a total of 6 SST sessions, 4 muscular hypertrophy sessions including the session from the 2nd week. The players also underwent a total of 3 speed and plyometric sessions.
The muscular hypertrophy sessions included 8 to 9 exercises in each session. The first 4 exercises were always compound lifts including Squats, Bench Press, Dead Lifts and Overhead Press. Minor adaptions were conducted from session to session by adjusting either the number of sets or intensity. Table 3 shows the reps, sets, and intensity used during the hypertrophy sessions.
The speed and plyometric sessions were divided into 2 parts. The initial part was 3 sets of 10 sprints for 15 meters. After each 15-meter sprint the player would jog back to the starting point and immediately begin the next sprint until completing 10 consecutive sprints. Each player was given 3 minutes rest between each set.
The plyometric phase included 3 sets of basic hurdle jumps. 6 hurdles were set up 5 feet apart while the height of each hurdle was adjusted according to the height of each players’ greater trochanter. 6 repetitions of 6 jumps constitute a single set. Each player was given 6-minute rests in between each set and no rest in between repetitions.
· Retest at 5 Weeks
After completing the 5-week training program, the athletes were retested for their strength and speed to assess their levels of improvement throughout the training program. All the participating athletes demonstrated positive increases
Exercise | Description | Fitness Component Targeted |
| Lateral single leg hops on and off an aerobic step. This exercise is intended to challenge unilateral balance and strength. This exercise also requires a great deal of coordination. | Unilateral Strength, Balance & Coordination |
| Resisted Static squats helps with building lower body strength and core strength. It is excellent for challenging balance. Static squats have also been proven to have positive effects on force production. | Balance, Core Strength & Static Strength |
| Squash is a unilateral sport and one of the best exercises to build unilateral lower limb strength is the Bulgarian squat. When performed correctly it will help to build both strength and improve mobility. | Unilateral Strength, Balance & Mobility |
| Plyometric jumps is a classic exercise used across all sports to build speed and power. During the SST phase, the emphasis was on developing technique as there is an increase in risk of injury when it comes to plyometric exercises. | Rhythm, Coordination & Power |
| BOSU Banded stars are functional core exercises which heavily includes balance. While sitting on a BOSU, the participant was asked to stretch the resistance band to form a star shape with all extremities extended. Co-contraction of the posterior and anterior chain is required to perform this exercise. | Core Stability & Balance |

4. Discussion
Little is known regarding the exact training protocol for elite squash athletes. The aim of this study was to observe and interpret the results of a 5-week linear periodization training regime on elite squash athletes consisting of 12 SSIPT, 4 Hypertrophy, 3 Speed and Power sessions. The results of our program show that there is a significant increase in post testing performance for all 5 athletes as compared to their pre-test results. For the 1-minute push up, athletes improved at an average of 54.78%, 1 minute sit up test showed an average improvement of 21.5%, half squat test exhibited an improvement of 7.8%, and all round improvements for 20 meter sprint test and adductor test for all 5 participants. Participants show all round improvements in all 5, 10 and 15 m sprints as well.
This advancement supports the initial hypothesis whereby elite athletes require different variations in their periodisation program to ensure progress is made over a longer period of time (Kraemer, Duncan, & Volek, 1998). The increase in volume contradicts what is typically seen in a traditional linear periodisation program where generally a taper in volume happens as the program progresses. A study done by (Häkkinen, Pakarinen, Alén, Kauhanen, & Komi, 1988) has shown that those who have already established a higher pretraining status (meaning to say, high performance athletes) will be limited to the amount of absolute strength gains when compared to the untrained. In contrary from amateurs and medium level athletes who only require low training stimulus to excel, elite athletes enhance their performance through larger amounts of training stimulus which can be tough to obtain from traditional training (Issurin, 2010).
In elite sport, coaches and applied sport scientists are constantly seeking and applying innovative training methods and optimal strategies to have their athletes achieve high performances (Gouttebarge, Moen, Boschman, & Kantebeen, 2013). To maximize the effectiveness of training, coaches and sport scientists need to evaluate the affects and consequence of training methods on a regular basis through the appropriate training protocols. Doing regular testing and measurement provides coaches and athletes with feedback that can be used to identify the shortcomings of an athlete and adjust training programs to improve those imperfections. Without this feedback, athlete may continue training ineffectively and fail to develop the fitness, skills, tactical awareness, and other capacities needed for competitive success (McAuliffe, 2010).
Reflecting on the data obtained, all athletes managed to show improvement in post test results proving the effectiveness of the program and continues to support previous studies done on elite level adaptations. Essentially coaches can play with training variations of certain fundamental aspects i.e. volume instead of going for more extravagant approaches such as High Intensity Interval Training (HIIT). A study done by (Rynecki, Siracuse, Ippolito, & Beebe, 2019) shows that there was a 144% increase in injuries involving both lower and upper body extremities due to the increase in HIIT interest from 2012-2016. Sport Specific Injury Prevention Training (SSIPT), however, was specially implemented in the program and showed no injuries among the athletes while training and post program for SEA Games 2019. Better neuromuscular adaptation was seen with sport specific resistance training as increases in electromyographic EMG amplitude and rate of EMG activation indicates improvements in the pattern of neural drive (P < 0.05) (Judge, Moreau, & Burke, 2003).
Our training intervention showed an application of Sport Specific Injury Prevention Training (SSPIT) and showed no injuries among the athletes while training and post program for SEA Games 2019. Better neuromuscular adaptation was seen with sport specific resistance training as increases in electromyographic EMG amplitude and rate of EMG activation indicates improvements in the pattern of neural drive (P < 0.05) (Judge, Moreau, & Burke, 2003).
What this study shows is that the methodology of our 5-week linear periodisation is effective in producing positive results for elite level squash athletes. Due to the limitations of a standard traditional periodisation that raises difficulties for progress in elite athlete’s variation needs to be included (Issurin, 2010). This study serves as a guideline to be used as a reference for future studies and training variations to be implemented. Many more in depth studies need to be done with varying training protocols in hopes of getting a baseline of reference for coaches and athletes to refer to. An increase in sample size could prove useful to collect more valid and reliable data with enough statistical power to produce results that reflect a more standardize truth. Comparisons between male and female squash athletes could also serve useful in determining the differences in adaptations between genders
5. Conclusion
During the 5-week training program, the athletes underwent a total of 12 SST sessions, 4 hypertrophy sessions and 3 speed and plyometric sessions. All the athletes displayed significant improvement in strength, muscular endurance and speed suggesting that a linear strength and conditioning program can be highly beneficial for squash players. Although the results of the study are positive, further research into various training programs is warranty to further understand the best possible approach for training elite squash players.
