OBJECTIVETo study the effect of acupuncture on skeletal muscle endurance in rats as a pre-games assistant training.

METHODSThirty male SD rats were randomly divided into 3 groups: control, model and acupuncture group. Acupuncture group was treated at "Dazhui" (GV 14), "Housanli" (ST 36) by twisting mild reinforcing-reducing method for 20 min, no interventions were added on control and model group. Muscle strength was detected in three groups under anaesthetic (after model established in model group, after model established and treated in acupuncture group). Averaged change percentage of mean skeletal muscle endurance (P(m)) and averaged maximum percentage of skeletal muscle endurance (P(max)) were evaluated.

RESULTS(1) 10P(m) in model group decreased more than acupuncture group statistically (P < 0.05); 20P(m), 30P(m) and 40P(m) in model group decreased significantly compared to those in control group and acupuncture group (P < 0.05, P < 0.01). (2) Changes of 10P(max) in acupuncture group was much less than in model group (P < 0.05); changes of 20P(max), 30P(max), 40P(max) and 50P(max) decreased more in model group than in acupuncture group and control group (P < 0.01, P < 0.05).

CONCLUSIONAs an assistant training method, acupuncture can postpone descending point of muscle strength endurance to delay sport fatigue.
