Effect of Complex Training on Jumping Variables During Heading the Ball for Soccer Players
The aim of research is to investigate the effect complex training on squat jump height (SJ), countermovement jump height (CMJ), ground contact time (GCT), jumping height during heading the ball (JHDH), total flight time (TFT), time to reach maximum height (TMH), and initial velocity (IV) during heading the ball from jumping. Experimental method was applied on a sample of 10 soccer players (mean +/- SD: 20.7 +/-1.2 years, 176.5+/- 7.3cm, 76.5+/-6.7 kg) by applying pre- and post-measurements. SJ, CMJ, and heading the ball from jumping tests were applied on the subjects respectively. Tests were recorded using a high frequency video camera (GoPro 3ed, 240 fps) and analyzed using (Tracker 4.96 video analysis and modeling tool). Eight week complex training program was applied 3 times a week. Results show significant differences between pre and post measurements in SJ (t= 11.78), CMJ (t= 6.30), GCT (t= 5.56), JHDH (t= 5.05), TFT (t=-4.895), TMH (t=4.895), and IV (t=-4.895) (p<0.05) for post measurements. Present results recommend involving complex training in the specific preparation phase for soccer players. We could conclude that complex training program increases vertical jumping performances and decrease GCT and TMH by inducing motor unit recruitment and stored energy in the muscle tendon unite during the shortening phase of the stretch-shortening cycle.
