Comparison between traditional resistance training and whole‑body electrical stimulation in improving muscular strength

Abstract

Background: Greater muscular strength can enhance the ability to perform general sports skills such as jumping, sprinting, and direction tasks. Resistance Training (RT) is broadly applied by strength and conditioning coaches to increase strength. However, Whole-Body Electromyostimulation (WB-EMS) recently served as an alternative method to increase muscular strength in high-performance athletes. This study aimed to examine the effects of two different training modalities on muscular strength. Methods: Sixty female collegiate softball players (Age = 23.52 ± 1.89 years; Height = 156.20 ± 1.71 cm; Mass= 53.21 ± 3.17 kg) were randomly assigned into 3 groups. All groups trained as usual for 8 weeks, with the first group performed 100 repetitions of dry swing (normal bat swing practice in softball). The second and third group performed a combination of dry bat swing with RT and WB-EMS, respectively. Muscular strength (upper body and lower body) for the 3 groups was evaluated before and after the 8-week program. Results: The main results showed that after the eight-week training, the upper and lower body strength significantly increased in both RT and WB-EMS groups compared to the control group (p = 0.000, and p = 0.000, respectively). While both groups contributed to the increase in muscular strentgth following 8 weeks of training, it was the RT that resulted in a larger magnitude of increase in strength. Conclusion: This study concluded that RT should be emphased in high performance athlete training while recognizing the potential benefit of WB-EMS in enhancing muscular strength.
