ABSTRACT |
The aim of this study was to determine the effects of the difference between the traditional Korean diet pattern and the traditional western diet pattern on muscle injuries due to high-intensity resistance exercise. Eight healthy males were voluntary participated in this study. All subjects were randomly received both Korean diet (KFT) and the Western diet (WFT) for 4 days with 2-week interval. Daily caloric content was about 3,500 kcal (carbohydrate: protein: fat; 70%: 15%: 15%, KFT; 34.5%: 16.7%: 48.3%, WFT). High-intensive 6set leg press exercise was performed at Day 1 and Day 2. Fasting blood samples were drawn from forearm vein and analyzed for glucose, insulin, lactate, creatine kinase, cortisol, and IL-6. Plasam glucose and insulin concentrations were not significantly different between KFT and WFT. Plasma creatine kinse activities at Day 5 were significantly lower in KFT than WFT (p=.010). Resting lactate levels in KFT was significantly higher than those in WFT (p =.010). IL-6 and cortisol levels were significantly lower in KFT than WFT (p=.017, IL-6; p=.006, cortisol). Therefore, the results of this study suggested that the KFT like the high carbohydrate meal could attenuate the muscle injury induced by high intensive exercise in the comparison to the WFT like the high fat meal. |
