PURPOSE: The purpose of this study was to examine the influences of biological maturation on body composition and motor fitness among young tennis players. METHODS: Forty-seven female players, 10.6-13.2 years of age (11.5 ± 0.7 years), were tested on stature, sitting height, body mass, skinfolds (triceps and medial calf), maximal isometric grip strength, and hexagon agility test. Body mass index (BMI) and body fat percentages (BF%) were calculated accordingly. Number of years of experience in regular tennis training, weekly training (tennis and fitness) volume and self-reported parental heights were recorded. According to their maturational status, estimated by percentage of predicted adult stature (PAS), they were classified into two groups as prepubertal (< 85% of PAS) and early pubertal (>85-90% of PAS). RESULTS: ANCOVA results, when chronological age was controlled as a covariate, revealed that early pubertal players were significantly taller and heavier and have higher values on BMI and BF% than their prepubertal counterparts. However, there were no significant differences between groups in grip strength and agility performances. Similar results were also observed on sports-specific experience duration and volume of weekly tennis and fitness trainings. CONCLUSION: Results of the study suggest that young female tennis players from distinct maturity stages may not differ in their muscular capacity and agility performances, but may differ in their body size and composition when they are trained similarly.
