Abstract
Neuromuscular electrical stimulation is one of the methods of strength development during which there is no voluntary muscle contraction. The aim of this study was to investigate the influence of the neuromuscular activation of knee extensors on vertical jump by using electrostimulation method. Ten healthy trained male students in sportssciences, aged 21-25 years, perform Sargent jump test. They perform two kinds of jump - squat jump and drop jump (42 cm heigh bench) immediately after electrostimulation and without electrostimulation. Both kinds of jump were performed with and without dynamic stretching. The subjects received electrostimulation for 2 minutes with preset program Explosive power on electrostimulator. We found no significant difference in measuring of heigh of squat jump, where neuromuscular activation by using electrostimulation method was or was not applied. The results showed that heigh of drop jumps significantly increased by using electrostimulation method +2,7 % (p = 0.005) with dynamic stretching and +3,3 % (p = 0.018) without stretching. The results showed that neuromuscular activation by using electrostimulation method (immediately before performance) can have positive effect on heigh of drop jump and so can be added to warm-up part before performance. Using electrostimulation method had no significant effect on squat jump performance.
