[Effects of different acupuncture and moxibustion methods on ultrastructure of gastrocnemius in rats].

Objective: To explore the efficacy differences in early intervention of different acupuncture and moxibustion methods on gastrocnemius fatigue in rats induced by electrical stimulation.

Methods: Fifty male SD rats were randomly divided into a control group, a model group, a hand acupuncture group, an electroacupuncture group and a moxibustion group, 10 rats in each group. Electrical stimulation of the sciatic nerve was given in the control group and gastrocnemius fatigue test was induced by electrical stimulation of the sciatic nerve in the model group after anesthesia without other treatment, but just take 6 times interval stimulation in the control group.

[Effect of acupuncture on regulating skeletal muscle endurance in rats].

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

Methods: Thirty 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.

[Effects of manual acupuncture and electroacupuncture on Ca2+ content and Ca2+ -ATPase Activity in sarcoplasmic reticulum of skeletal muscle cells in rats during acute swimming exercise].

Objective: To observe the effects of manual acupuncture (MA) and electroacupuncture (EA) on Ca2+ content and Ca2+ -ATPase activity in sarcoplasmic reticulum of skeletal muscle cells in rats of acute swimming exercise (ASE) so as to reveal its underlying mechanism in strengthening motor abilities.

Methods: Sixty male SD rats were randomly divided into control, model, MA and EA groups, with 15 cases in each. Rats in MA group and EA group were treated respectively with MA (120-140 twirlings/min, 30-60 s/time every 3-5 min) and EA (500-800 Hz, 0.
