The purpose of this study was to investigate skeletal muscle fatigue with electrolyzed-reduced water (ERW) in collegiate athletes. Ten collegiate basketball male players aged 20 ± 1.47 years were recruited in this study. All subjects were free of any drugs and ergogenic acid such as ginseng and vitamins. Subjects were randomly divided into two groups (ERW group and placebo group). Each group received ERW or placebo (7 ml/kg body weight) for 14 days. Electromyography (EMG) responses of left quadriceps muscles (rectus femoris; RF, vastus lateralis; VL, vastus medialis; VM) during 40 maximal eccentric, isokinetic muscle action was examined, and then each group received additional ERW or placebo for 3 days. The same protocol was repeated. EMG amplitude demonstrated that there was a significant negative linear relationship (p<.05) for RF, VL and VM of %MVC in ERW group, while there was no significant negative linear relationship for VL in placebo group. After three day resting period, EMG amplitude also demonstrated that there was significant negative linear relationship (p<.05) in RF of %MVC, VM of %MDF in ERW group, while there was no significant effect in RF of %MDF in placebo group. Thus, the results showed that ERW enhanced skeletal muscle fatigue in collegiate athletes. It is concluded that ERW may be effective to improve the recovery time from skeletal muscle fatigue after competition. |
