Impact of Lower-Limb Asymmetries on Physical Performance Among Adolescent Female Tennis Players
This study aimed to determine the correlation between interlimb asymmetries and physical performance metrics in adolescent female tennis players. Methods: Twenty-five female tennis players (age: 13.29 ± 0.98 years; weight: 52.52 ± 7.31 kg; height: 162.91 ± 6.02 cm) consented to participate in this s...

| Summary: | This study aimed to determine the correlation between interlimb asymmetries and physical performance metrics in adolescent female tennis players. Methods: Twenty-five female tennis players (age: 13.29 ± 0.98 years; weight: 52.52 ± 7.31 kg; height: 162.91 ± 6.02 cm) consented to participate in this study. Their performance was evaluated using various variables, including bilateral and unilateral countermovement jump (CMJ), bilateral and unilateral horizontal jump (HJ), 180° change of direction (180COD) conducted with both the right and left legs, and a 20 m sprint. The systematic bias was evaluated by one-way repeated measure analysis of variance, Pearson’s correlation test for relationships between variables, and the kappa coefficient for consistency in the asymmetrical direction. Results: Significant relationships were found between CMJ asymmetry and the variables HJR (r = −0.47) and HJL (r = −0.44). In addition, significant relationships were found between HJ asymmetry and the variables CMJR (r = −0.60) and CMJL (r = −0.54), HJR (r = −0.64), HJL (r = −0.67), CMJ (r = −0.55), and HJ (r = −0.52). Conclusion: Jumping tests are important indicators of performance loss in female tennis players. In addition, no significant correlation was found between the 180COD and performance tests, suggesting that asymmetries in COD do not affect jump performance or speed. Based on these results, it is recommended to integrate individualized programs for each athlete to reduce asymmetries. |
