Effects of Acupuncture On Mitochondria of Muscle Cell In Rats of Acute Swimming Exercise

Objective To research on the effects of acupuncture and electroacupuncture on antioxidant enzymes activity, Ca2+ content and Ca2+-ATPase regulation in rat muscle mitochondria after acute swimming exercise. Method Forty male SD rats were divided randomly to 4 groups. The rats in the acupuncture group and electroacupuncture group were respectively treated by the two different methods of acupuncture and electroacupuncture before acute swimming exercise. After the swimming exercise, the rats were executed and the needed materials were taken. Then the relational indexes were determined. Result After acute swimming exercise, the values of GSH-Px activity and Ca2+-ATPase in rat muscle mitochondria in the swimming groups decreased obviously than those in the control group (P<0.05), and the values of Ca2+ content increased obviously (P<0.01). In acupuncture group, SOD activity increased obviously (P<0.05). Compared with swimming team, GSH-Px activity and Ca2+-ATPase in acupuncture group increased obviously(P<0.05). Ca2+ content in swimming group and electroacupuncture group obviously increased than that in control group (P<0.01). Conclusions Acupuncture can protect cells to avoid the acute sports injury, maintain the functions of mitochondria so as to postpone fatigue, extend muscle working time and prevent muscle injury.
