ELECTRICAL MUSCLE STIMULATION (EMS) IMPLEMENTATION IN EXPLOSIVE STRENGTH DEVELOPMENT

Sport Mont 2013, XI(37-38-39), 207-211

Abstract

Electrical muscle stimulation (EMS), is also known as neuromuscular electrical stimulation (NMES) may be used for therapeutic purposes and training. EMS is causing muscle contractions via electrical impulses. The survey was conducted as a case study. The study was conducted on subject of 3 male of different ages. The study lasted 4 weeks, and the respondents have not used any type of training or activity, which would affect the development of explosive strength of the lower extremities. Electrical stimulation was performed in the evening, every other day, with COMPEX mi sport apparatus (Medical SA - All rights reserved - 07/06 - Art. 885,616 - V.2 model). In 4 week period, a total of 13 treatments were performed on selected muscle groups - quadriceps femoris and gastrocnemius. Program of plyometric training (Plyometric) (28 min per treatment), for each muscle group were applied. The main objective of this study was to quantify and compare explosive leg strength, using different vertical jump protocols, before and after the EMS program. The initial and final testing was conducted in the laboratory of the Faculty of Sport and Tourism in Novi Sad, on the contact plate AXON JUMP (Bioingeniería Deportiva, VACUMED, 4538 Westinghouse Street Ventura, CA 93 003) under identical conditions. In all three of the respondents indicated an increase in vertical jump in all applied protocols.
