| Abstract |
Eccentric exercise damaged the skeletal muscle, causing soreness, swelling, tenderness. Exercise induced muscle damage (EIMD) increases possibility of injury and decreases performance of eccentric exercise. Previous studies have been interested in measuring and improving recovery of EIMD, but there have been controversial results. Therefore, the purpose of this study was to investigate the effects of the Cervus elaphus (deer velvet) on recovery of EIMD after eccentric exercise. Twenty female college students participated in this study. Subjects were divided into two groups (Cervus elaphus group and placebo group). The subjects were randomly assigned to either Cervus elaphus group (n=10) or placebo group (n=10). Each group received either Cervus elphus powder (2000 mg/day) or placebo capsule (2000 mg/day) for 14 days, and then for 7 days after eccentric exercise. For Eccentric exercise knee extensors and flexors were performed by isokinetic dynamometer (Cybex 770) on 15th day, 50 times, 3 sets. CK, GOT, Myglobin and VAS were measured right before eccentric exercise and at first, second, seventh day during recovery. CK and GOT were significantly increased in placebo group after eccentric exercise, while there were no differences in CK, GOT, myoglobin, and VAS between tow groups across the times. It is concluded that Cervus elphus may be effective to reduce muscle damages and improve recovery from eccentric exercise. Further study about functional change after eccentric exercise with a dose of Cervus elphus is needed in the future. |
