Abstract

V originále

Neuromuscular electrostimulation is one of methods of strength development during which there is no voluntary muscle contraction and there is required an apparatus which sends electrical impulses. The purpose of this study is to find out if neuromuscular activation by using electrostimulation method, performed before performance as a part of warm-up, is beneficial for performance in countermovement jump. As participants we chose 10 healthy trained men aged between 21 and 25 years. During warm-up test subjects pedalled on a stationary bike for 5 minutes. Then performed countermovement jumps immediately after electrostimulation (applied on quadriceps femoris muscles) or without electrostimulation or with dynamic stretching. Three attempts were permitted and we recorded the best of them. There were four variants of intervention before performance-with and without electrostimulation and with and without dynamic stretching. Dynamic stretching involved the whole body, contained the same exercises and lasted for 5 minutes. Electrostimulation was applied for 2 minutes with the pre-set program "Explosive power" on an electrostimulator. The results showed that the height of countermovement jump significantly increased after using the electrostimulation method: +1.8 % (p = .036; d = .19) without dynamic stretching and +1.8 % (p = .036; d = .19) with dynamic stretching compared to attempts without electrostimulation. We found no significant difference (p > .05) if we compared performance in countermovement jump after warm-up and electrostimulation and performance after warm-up and dynamic stretching. This finding suggests that electrostimulation applied before exercise can be beneficial as well as dynamic stretching. Performances in countermovement jumps after electrostimulation are statistically significantly higher than performances without electrostimulation. However, we can say that the neuromuscular activation via the electrostimulation method (immediately before performance) helps to improve the performance in countermovement jump at least as well as dynamic stretching. This study provides further evidence of a link between a type of stretching or neuromuscular activation before performance and a level of performance in vertical jump, specifically countermovement jump.
