Comparison between Traditional Resistance Training and Whole-Body Electrical Stimulation in Improving Muscular Strength
Keywords:electromyostimulation, strength, intensity, repetition maximum
Greater muscular strength can enhance the ability to perform general sport skills such as jumping, sprinting, and change of direction tasks. Traditional Resistance Training (TRT) is broadly applied by strength and conditioning coaches to increase strength. However, recently, Whole-Body Electromyostimulation (WB-EMS) has been proven to be able to increase muscular strength in high performance athletes. The aim of this study was to examine the effects of two different training modalities on muscular strength. Sixty female collegiate softball players (Age = 23.52 ± 1.89years; Height = 156.20 ± 1.71 cm; Mass = 53.21 ± 3.17 kg) were randomly assigned into 3 groups. Along 8 weeks, all the groups trained like usual, but the first group performed additional of whole-body electrical stimulation (WB-EMS), the second group performed additional of traditional resistance training (TRT), and the third group (CTR) did not perform any additional training after regular softball training. Before and after the 8-week program, muscular strength (upper body and lower body) was evaluated in the 3 groups. The main results showed that after 8-week training, the upper body strength was significantly increased in TRT and WB-EMS groups in comparison with CTR (p = 0.000, and p = 0.000, respectively). However, t value showed greater improvement of upper body strength in TRT (7.37) group compared to WB-EMS (2.37) group. Similar finding on lower body strength where TRT and WB-EMS groups showed significant increase compared to CTR group (p = 0.000, and p = 0.000, respectively). Moreover, t value showed greater improvement of lower body strength in TRT (8.40) group compared to WB-EMS (3.97) group. The findings of this study highlighted the efficiency of both training modalities to improve muscular strength but also suggested that the traditional resistance training should be emphasize in improving muscular strength compared to utilizing whole-body electrical stimulation training.
