Conclusion: It is concluded from this study that plyometric training is effective in improving agility of the cricket players. Players can improve their performance by working on plyometric training and agility.

Keywords: Agility, athletes, cricket player, athletic performance, plyometric training, vertical jump.


Over the past two decades cricket attains a rise in its popularity with over 100 nations registered with International Cricket Council (ICC)1. Cricket is the most commonly played game of the present era with different formats like T20, One Day International and test matches2,3. The cricket players are exposed to more demanding schedules because of the longer season with more time spending on training and practice4. Players are required to produce certain and quick movements during the play so that there must be intact physiological and neuromuscular coordination5. Therefore, fitness for cricket players is an important component for best performance in field and also the lower limb muscles are used for powerful activities6. There are different distinct psychological demands in cricket according to playing positions7. Thus, the professional cricket players face unique competitive demands that require psychological and behavioral control to manage the stress and under pressure performance8.

Studies report different sites of injuries in cricket9. The upper limb injuries in cricket accounts for 19.8-34.1% of the total Injuries whereas injuries to the lower limb varies from 22.8% to 50.0%4,10. The hamstring strain remains the most common with highest prevalence over the decade11.  Study reported that incidence of hamstring strain was placed fourth in 2006 to 200712. From 2007–2008 onward, though, hamstring strains have been the most common injury every season13. Lack of flexibility, muscular strength imbalance, previous history of injury and age are considered risk factors of hamstring injuries14. Associations of cricket issued recommended international consensus definitions methods for the injury monitoring in 2005 which further updated in 201611. This has given rise to cricket injury surveillance publications that have employed relatively consistent methodologies15,16.

Interventions put in place to reduce the incidence of hamstring strain injuries by addressing modifiable risk factors have focused primarily on increasing eccentric strength, correcting strength imbalances and improving flexibility17. A new and famous strategy of exercise which is considered less time consuming and very effective to prevent from injury is plyometric training18. Plyometric are training techniques used by athletes in all types of sports to increase strength and explosiveness19. Plyometric training involves high intensity movements such as jumping, bounding exercises that needs to be performed explosively and quickly20. These quick movements are more often related to development of agility21.

Agility is the ability of an individual to produce and synchronize quick movements in an effective manner22. A study conducted in 2011 concluded that speed, agility and quickness physical activity program intervention had a progressive outcome on power performance in young soccer athletes23.

There are different studies conducted to determine the effect of plyometric training on agility, studies show role of 7-8 weeks effect of plyometric training on agility. There is no study conducted yet to determine the effect of 4 week of plyometric training on agility in cricket players. The objective of the study is to determine the effect of plyometric training on agility in cricket players.


The study design was randomized controlled trial and carried out from Aug 2019-Jan 2020 (06 months) at Al Nazar Cricket academy Rawalpindi. Ethical approval was taken from the research committee of Riphah International University, Islamabad and trial registry was also done in US clinical Trial Registry before recruiting the participants (NCT04350385). Sampling technique was Non-Probability Purposive Sampling. Sample size was calculated by using open epi tool. 40 players who fulfill the inclusion criteria were divided randomly into two groups. 18 players were included in control group and 19 players were included in experimental group. Consent was taken from very participant before the assessment. Those players who registered with the club from last one year, actively participating in the training programs, aged between 18-25 years were recruited in the study. Those players who suffered from any musculo-skeletal or sports related surgery in last 6 months were removed from the study. Agility of players were assessed at baseline on zero week through T agility run test,24 Illinois test25 and vertical jump26 were assessed through squat vertical jump. Data entry and analysis were done through SPSS version 23.  Test of normality (Shapiro Wilk Test) were applied before further analysis to check normal distribution of data.


There are 37 participants in this research under age group of 18 to 25. Male cricket players who registered with the club from at least one year were recruited. It has been checked that all male cricketers did not participate in any periodized resistance training program. The demographic information of study shows that Mean ±Standard Deviation of athlete age is 21.29±1.63 years. The mean ±SD of weight in kg is 65.97± 4.79 and mean value and SD of height in inches is 68.15± 1.20 with mean ±SD of BMI 21.94±1.62. Mean value and SD of experience of players in game is 2.38±0.59.

The mean value ±SD of a T agility test in control group pre intervention is 21.37 ±3.07 and in experimental group is20.87±3.09. The mean value and standard deviation of Illinois agility test of control group pre intervention is 22.90 ±1.58 and experimental group is 23.07 ±1.45. The mean value ±SD of vertical jump height in control group pre intervention is 18.00±1.92 and in experimental group is18.36 ±2.19. The mean value and SD of T agility test in control group post intervention is18.33±5.03 and in experimental group is14.19±4.02 with p value (0.009). The mean value and standard deviation of Illinois agility test of control group post intervention is 19.74±0.79 and for experimental group is 17.34±0.69 with p value (0.001). The mean value and SD of vertical jump height in control group post intervention is 25.18 ±2.11 and in experimental group 31.90 ±2.55 with p value (0.001).


The study aims to determine the effects of dose response of plyometric training program on speed and agility in young cricket players. This study is based on three tests, T test, Illinois test and Vertical height jump test that are performed on interventional based two groups experimental with 6 weeks of training protocol. Performing these tests before and after intervention, it has seen that plyometric training has a significant effect on speed of the cricket players. The plyometric group shows improvement in speed and agility but the group with traditional training program has no improvement in results. This study shows significant improvement in the speed and agility test measures after plyometric exercises.

The finding of study is that the cricket players who added plyometric training with their traditional program shows improvements in the speed and agility as compared to other cricket players who just focus on their traditional training program and are not included in plyometric training group. This study is specially targeted to the club cricket players engaged to the plyometric training program. The plyometric training not only improves speed and agility but it also improves the strength and power of athletes. The improvement in speed and agility is helpful for the cricket players while performing in the game on various aspects like fielding, bowling and batting. Potteiger et al conducted a study on plyometric training and reported that good coordination between brain and proprioception leads to enhance motor units21. It is not clear yet that this adaption is due to neuronal firing or impulses came from the spinal cord27.This study showed that plyometric training improves the physical fitness and strength of cricket players. Michael G. Miller et al reported in a research that plyometric is effective in enhancing agility of athlete’s after 6 week application of plyometric28.

In our study, significant difference occur in players agility after plyometric training in experimental group This effect in agility and speed is good for young cricket players where they need quick change in position as demand of the sport. Parsons and Jones et al conducted a research who recruited long tennis players for plyometric training and concluded that there was significant improvement happen in agility and speed of players29. Renfro conducted a study with title Summer Plyometric Training on soccer players and concluded that there were better gains in agility and speed30. A variety of training studies showed that plyometric training with agility enhances the performance of athletes as well as strength and power also. Another study conducted by Robinson and Owens to assess agility measured by vertical, lateral and horizontal plyometric jumps and stated that there were significant improvements in agility.

Various studies reported utilizing plyometric training have shown improvements in different areas of different sports, including vertical jump in basketball31 and G Markovic et al conducted a research on neuro-musculoskeletal and effect on lower limbs performance and reported an effective plyometric exercise in enhancing strength of lower limbs and power in adults32.


It is concluded from this study that plyometric training is effective in improving agility of the cricket players. Players can improve their performance by working on plyometric training and agility.
