The purpose of this study aimed to examine how a six-week plyometric training regimen affected male athletes' agility, explosive power, and acceleration. Sixteen athletes consented for the study and were divided into two groups: the plyometric training group (n=8) with an average age of 16.4 ± 0.5 years and weight of 60.9 ± 7.2 kg, and the control group (n=8) with an average age of 16.4 ± 0.5 years and weight of 63.0 ± 3.4 kg. The plyometric training group participated in a combination of plyometric exercises and general tennis training, while the control group received only general tennis training. Pre-and post-testing included the T-test and 505 agility tests to assess agility, vertical jump tests for explosive power, and a short-distance acceleration test. Pretest scores were utilized as covariates in univariate analysis of covariance (ANCOVA) to examine change scores (post-pre). In comparison to the control group, the results revealed appreciable gains in the plyometric training group for all variables that were assessed. The T-test agility measure demonstrated a significant group effect
Physical and performance correlates of agility in tennis players
2013
Purpose: The purpose of this study was to evaluate the relationships of body mass index (BMI), years of sport-specific training, power, and reaction time with simple agility measured in tennis players. Methods: Thirty participants were recruited from local tennis teams and clubs in Ithaca, NY. Participant age ranged from 18 to 39 years (M = 22.7, SD = 5.8). Participants performed an Agility T-Test, a 505 Agility Test, a Vertical Jump Test and a Reaction Time Test in the Biomechanics Lab at Ithaca College. Participant data including age, height, mass, gender, years of sport-specific training and BMI were recorded for each individual prior to testing. Pearson correlations were used to evaluate bivariate relationships between BMI, years of sport-specific training, power, reaction time, and Agility T-Test and 505 Agility Test. Also multiple regressions were completed to determine the prediction strength of selected variables for agility performance and also prediction strength for all the variables combined together. Results: A negative and significant correlation existed between power and Agility T-Test (r =-0.58, p < .01) and power and years of training (r =-0.40, p < .05). The correlation between power and 505 Agility Test approached significance (r =-0.30, p = .057). Also, a positive and significant but weak correlation existed between BMI and 505 Agility Test (r = 0.39, p < .05). Surprisingly, no relationship existed between other variables. Multiple regression analysis revealed that BMI, years of training, PPO and reaction time best predicted agility time for both the 505 Agility Test (R 2 = 0.48) and Agility T-Test (R 2 = 0.64) iv Conclusion: Under the present experimental condition, Agility T-Test and 505 Agility Test scores were best predicted by all variables together. Since agility is related to successful performance, this information may be helpful to coaches, athletes and recreational populations. v ACKNOWLEDGEMENTS I sincerely thank and express my gratitude to the following individuals for their assistance, guidance and insight throughout this thesis.

Effect of plyometric training on jumping performance and agility in adolescent badminton players
Turkish Journal of Sport and Exercise, 2017
Badminton is one of the most popular racquet sports in the world. The agility and vertical jump are important motor skills to hit a shuttlecock in badminton game. The purpose of this study was to investigate effect of plyometric training on vertical jump and agility in adolescent badminton players. Twenty adolescent (age, 12.5 ± 0.2 years) badminton players were randomly divided into two groups as plyometric group (PG) and control group (CG). All participants were tested to assess agility and vertical jump before (pre-test) and after 6-weeks training period (post-test). Agility performance was assessed with Illinois Agility Test. Vertical jump height was measured with squat jump test using a contact mat. The PG performed plyometric training twice a week, for 6 weeks. There was a significant difference between pre and post-test for squat jump test in both PG (26%) (p = 0.00) and CG (10%) (p = 0.016). However, squat jump height significantly increased in PG compared with CG (p = 0.024). The agility significantly improved in PG (6%) (p = 0.01), but not CG (2%) (p = 0.294). Our results show that a six week plyometric training improved agility and vertical jump in adolescent badminton players. Badminton game requires fast changes in direction, vertical jumps, forward lunges around the court. Badminton coaches should take place plyometric exercises in training program.
Journal of human kinetics, 2017
Agility is an important quality in tennis, yet there is an evident lack of studies focussing on the applicability of tennis-specific agility performances and comparing them to equivalent non-specific agility performances. The aim of this study was to evaluate the reliability and factorial validity of three tests of pre-planned agility, performed in specific (with a tennis racquet) and non-specific (without a tennis racquet) conditions. The sample consisted of 33 tennis players (13 males and 20 females; age: 18.3 ± 1.1 years and 18.6 ± 1.3 years; body height: 185.4 ± 51 cm and 169.3 ± 4.2 cm, 74.0 ± 4.4 kg and 61.2 ± 3.1 kg, respectively). The variables comprised three agility tests: a 20-yard test, a T-test and the Illinois test, all performed in both specific and non-specific conditions. Between-subject and within-subject reliability were found to be high (Cronbach Alpha: 0.93 to 0.98; Coefficient of Variation: 3 to 8%), with better within-subject reliability and stability of the m...
Effects of different maturity status on change of direction performance of youth tennis players
Biology of Sport
The aim of this study was to examine the maturational status (i.e., peak height velocity [PHV]) differences in neuromuscular performance (i.e., vertical jump, linear sprint, change of direction (COD) using different tests, and change of direction deficit [CODD]) of young tennis players. One hundred and two tennis players (70 boys and 52 girls; age 13.9 ± 2.0 years, body mass 53.3 ± 12.7 kg, height 163.1 ± 11.9 cm) participated in the study and were divided into Pre-PHV (n = 26), Circa-PHV (n = 33) and Post-PHV (n = 43) groups. Testing included speed (5, 10, and 20 m), COD tests (i.e., modified 5-0-5, pro-agility and hexagon), and bilateral/unilateral countermovement jump (CMJ). Pre-and Circa-PHV players presented lower levels of performance in jumping ability (i.e., both bilateral and unilateral CMJs; P < 0.001; ES: 0.85 to 0.98), linear sprints (5 to 20 m; P < 0.05 to < 0.001; ES: 0.67 to 1.19) and COD ability tests (modified 5-0-5 test, proagility and hexagon) compared to the Post-PHV players. Moreover, Pre-PHV players presented lower CODD% (p < 0.05; ES: 0.68-0.72) than Post-PHV for both forehand and backhand sides, and Circa-PHV showed lower values in the CODD of the rolling situation to the forehand side (p < 0.05; ES: 0.58). Among the COD tests, the pro-agility test seems to be a simple, easy-to-implement and reliable test, which can provide interesting information about the COD with higher entry speeds. Moreover, specific training strategies related to the PHV and focused not only on the neuromuscular training and COD workouts, but also on maximizing motor skill proficiency, should be recommended.
INTRODUCTION: Tennis can be characterized as a strength-power sport requiring athletes to express intermittent bouts of high power outputs over an extended period of time (Kovacs, 2007). It is not uncommon for athletes to achieve ball velocities of 134-201 km • h-1 with average point lengths of <10s, and work to rest ratios of 1:3-1:5. To achieve this, athletes need to be able to impart high ground reaction forces with their lower extremities, which are transferred through the trunk to the shoulder and arm (Chandler, 1995). While there are many studies evaluating tennis players in cross-section, there is a paucity of longitudinal research on tennis athletes (Kraemer et al., 2000; Salonikidis & Zafeiridis, 2008). The available studies are <9 months in duration and do not take into consideration individual adaptations to training. Studies spanning multiple years of an athlete's career have been conducted with other athletes (e.g. Baker, 2001; French et al., 2004; Kavanaugh e...
Reliability, Validity and Sensitivity of Newly Developed Tennis-Specific Reactive Agility Tests
Sustainability
Agility is one of the motor skills on which success in tennis performance depends, and the aim of this research was the development and validation of a new test for assessing preplanned and reactive agility in young tennis players. The sample of respondents comprised 50 young competitors with an average age of 12.34 ± 1.22 years who were ranked up to 50th in the national tennis association ranking and up to 300th in the international Tennis Europe ranking. Agility variables were measured with newly constructed tests for the assessment of preplanned agility (CODS) and reactive agility (RAG), which were constructed in such a way that subjects imitated specific movements in tennis. It can be concluded that the newly constructed tests of preplanned agility (CODS) and reactive agility (RAG) have a high degree of reliability. Additionally, the assumption that the reliability will be slightly higher for preplanned agility tests (CA = 0.92 and 0.92; ICC = 0.86 and 0.82) than for reactive ag...
