Abstract


This study examined the effects of 8 weeks additional dynamic Whole-body Electromyostimulation (WB-EMS) on muscular strength and batting velocity performance in female collegiate softball players. Forty softball players were randomly assigned into 2 groups which are DS (n = 20); DS-EMS (n = 20). Both groups performed 100 normal swing training using a standard bat. However, DS-EMS group performed additional of whole body electromyostimulation after the dry swing training. The training programs were conducted three times a week and all players were tested before (baseline) and at the end of week 8 (wk-8) training. Both groups showed statistically significant increase in predicted 1RM torso rotational strength (p ≤ 0.01) and batting velocity strength (p ≤ 0.01) after 8 weeks of training. In addition, WB-EMS group showed significant increase in predicted 1RM bench press, and predicted 1RM squat (p ≤ 0.01). When comparing between groups, WB-EMS showed statistically greater increases (p ≤ 0.01) in BV compared to control group. These data indicate that an 8-week of additional dynamic WBEMS training can significantly increase strength (upper-body, lower-body, torso rotational) and batting velocity among female collegiate softball players.
