Abstract:

BACKGROUND: Studies have shown that compared with the people with small muscle strength, the probability of early death due to cardiovascular diseases is reduced by 20%-35% in the people with large muscle strength; the suicide rate of people with strong constitution in the adolescence is 20%-30% lower than that of people with poor constitution, and the possibility of psychosis and mood disorders is also reduced by 65% in the people with strong constitution. Therefore, to enhance the body’s muscle strength can effectively protect human physical and mental health.
OBJECTIVE: To regulate the elbow and knee joint in the aspects of thought, qi, and motion through the joint exercise based on TCM principle in order to improve the immune function of human body.
METHODS: Sixty male college students at sophomore year were randomly selected and subject to the joint exercise twice a week, 1 hour once, totally for 8 weeks. Isokinetic motion, consisting of flexion 60°/s and extension 60°/s, five times, was done and detected with an IsoMed 2000 isokinetic dynamometer for measurement of muscle strength of the elbow and knee joint.
RESULTS AND CONCLUSION: After 8 weeks of joint exercise, the flexion and extension peak torque of the elbow, peak torque ratio, and average range of motion were significantly increased (P < 0.01); the flexor work was improved, but the extensor work was reduced slightly; there was a significant difference in the extension peak torque of the knee joint (P < 0.05). These findings indicate that the joint exercise can greatly increase the muscle strength of elbow flexor muscles, but has no effects on the muscle explosive power of the knee joint. In addition, the joint exercise can obviously improve the flexibility and balance and coordination ability.
