A comparative study of some kinematical characteristics for front jump set between male and female volleyball players
(Eine vergleichende Untersuchung ausgewählter kinematischer Kennzeichen des Sprungs am Netz zwischen männlichen und weiblichen Volleyballspielern)
The study aims to kinematically compare the front jump setting techniques between male and female volleyball players through recognizing the quantitative differences in some kinematical variables of male and female techniques. The sample has been selected intentionally from some premier league clubs players with a total of 10 players. Five male players (age: 25.3±2.5years; height: 188.0±3.5cm; body mass: 83.2±6.0 kg; mean ±SD, respectively) and five female volleyball players (age: 23.6±2.2 years; height: 178.0±5.1cm; body mass: 79.2±5.5 kg; mean ±SD, respectively) participated in this study. The researcher used the descriptive methodology using surveying approach by video and analyzing using the computer two synchronized digital video cameras (Panasonic - nv.3000EM) to record the subjects. A dependent sample t-test was used to test the variables between male front jump setting performance (MJS) and female front jump setting performance (FJS). The results indicated that MJS had significantly greater resultant CM velocity than FJS at takeoff. The MJS also had greater jump height, vertical displacement, velocity, angular velocity than FJS at contact ball. Shoulder velocity, angular velocity was larger in MJS but with no significant difference (p = 0.106, 0.357). The MJS had significantly greater resultant in ball angle, angle of projection and height release than FJS at contact ball. The MJS also had greater ball R. Velocity than FJS at contact ball. But there was no significant difference (p = 0.46) in ball y. velocity. The FJS had significantly greater resultant ball x. velocity than MJS at contact ball. This study provides information for coaches in teaching volleyball setting techniques.
