comparison of unilateral counter movement jump parameters in basketball and volleyball

Jumping capacity in basketball and volleyball comes to the fore in terms of performing the actions in offensive and defensive at the optimum level. so; it is thought that examining the performance levels of the legs separately during jumping will reveal important findings in terms of determining the possible strength and other differences. the aim of the study is to compare unilateral counter movement jump (cmj) parameters in basketball and volleyball. the study group consisted of 50 male athletes (21 basketball, 29 volleyball players) playing actively in turkish basketball and volleyball leagues during 2020-2021 season. unilateral cmj test was applied to the athletes by using the kistler force plate, following the standard warm-up protocol. the mean values of three successful jumps were recorded. groups homogeneity was determined by the levene test; the difference of the variables between the groups was determined by the independent sample t test and the significance level was set at p<0,05. it was determined that volleyball players showed statistically better scores, especially in left leg cmj parameters compared to basketball players. results indicated that volleyball players have better values in both left and right leg “jump height” and “active movement time” parameters (p<0.05). when the findings of the two sports where the jumping is used intensively are examined; volleyball players' better results in parameters characterized by vertical jump are thought to be related to the factors such as unilateral jumping in volleyball is dominant in most techniques, athlete profile and body composition.
