摘要：The aim of this study is investigate some physical and physiological parameters of junior tennis players of 8 years old and to understand the relationship of these parameters with their groundstroke performance. The sampling group of the study consists of 8 girl and 8 boy junior tennis players, 16 in total. Static stability, dynamic stability, star test, speed, ball throwing, flexibility and Hewiit test scores have been measured. The results have been analyzed with SPSS package program. Descriptive statistics of the analyses have been evaluated with Mann-Whitney U Test in order to define the differences of variables of two groups. Relationships between the variables have been investigated with Sperman correlation coefficient. A significant statistical difference has been found between the male and female junior tennis players in terms of vertical jump, star test, ball throwing and groundstroke (Hewitt) test averages (p<0,05, p<0,01). While a negative relationship has been found between the groundstroke performances of junior tennis players (Hewitt test) and the star test and the speed test; a positive relationship has been found with vertical jump (p<0,05, p<0,01). As a result, it has been found that junior tennis players show some physical differences and there is a relationship between the physical features and groundstroke performance of junior tennis players.
