- Abstract
The purpose of this study was to identify the differences in the sexual maturity level among tennis players on a sample of 95 players (53 boys and 42 girls) in the category between the ages of 12 and 14, in order to indicate the inadequacy of these competition categories. For the purpose of a self-evaluation of the sexual maturity level, a questionnaire was used, and basic morphological parameters were measured (height, weight, fat, BMI). A significant correlation between biological development and age (r=0.47-0,69), height (r=0.45-0.67), and weight (r=0.43-0.68), was determined. The variance analysis shows that the older group is at a higher level of biological development (p<0.05). The male subjects statistically differ in a significant way in terms of their biological development level (T1, p=0.00, T2, p=0.00) and the trend is followed by height (p=0.00) and weight (p=0.02). The female subjects statistically differ in a significant way in terms of their biological development level (T1, p=0.00, T2, p=0.01) as well as in all of the morphological parameters (height, p=0.00, weight, p=0.00, %FAT, p=0.01, BMI, p=0.04). Our findings indicate that it is necessary to change the official propositions of the competitions in this category because it could be expected that due to the reduced span of chronological age, fewer varieties are possible in the biological age of tennis players.
