| ABSTRACT |
|
This study was performed to analysis the expression of αB-crystallin, HSP 27, HSP 70 and cytochrome c by acute exercise in training and nontraining groups. The Male SD rat trained to run treadmill for 16M/min, 10° intensity(LT group) and 27M/min, 10° intensity(HT group) during 8 weeks. After interrupting 96H exercise, acute exercise and endurance training groups ran the treadmill running for 90min, 23m/min, 10°. Soleus/extensor digitorum longus muscle was extracted at the end of exercise and 24H recovery period. Small HSP, HSP 70, cytochrome c and muscle damage factor were analysed by western blotting. Small HSP were significantly increased in early stage of exercise. Also HSP 70 expression at the recovery. These results showed that the small HSPs may function as stabilizer of disrupted myofibrillar structure at the early stage of execise. and HSP 70 expression at the recovery period showed that the HSP 70 was involved in recovery and remodeling and adaptation processed in skeletal muscle. |
| Key words:
cute execise, low/high intensity endurance training, early small HSP expression. |
