The authors divided 88 male SD rats into 11 groups (group A: 1 calm con-trol group; group B: 4 natural recovery after exercising groups, i.e. model groups; group C: 3 after exercising + hot water groups, i.e. model + hot water groups; group D: 3 far infrared ceramic microsphere intervention after exercis-ing groups, i.e. model + ceramic microsphere groups), let the rats exercise to an exhausted condition by utilizing the treadmill experiment, measured and analyzed the experimental data of the rats in various groups respectively at calm, at the moment immediately after exercising, at 24 h, 48 h and 72 h after exercising, and revealed the following findings: at 24 h and 48 h after exercising, the blood CK, CK-MM, LDH enzyme activities of the rats in the far in-frared ceramic microsphere groups were lower than those of the rats in the conventional recovery groups and exer-cising groups. The results indicated that the far infrared ceramic microsphere therapy played a role in reducing the permeability of skeletal muscle cell membrane and protecting skeletal muscle micro-damage. |
