PURPOSE: The purpose of this study was to determine the difference between the traditional Korean and western diet on muscle injuries induced by high-intensity resistance exercise. METHODS: Eight healthy males were voluntary participated in this study. All subjects were randomly received both the Korean diet (KFT)

... d the Western diet (WFT) were provided for 4 days with 2-week interval between treatments. Daily caloric content was about 3,500 kcal (carbohydrate: protein: fat; 70%: 15%: 15%, KFT; 34.5%: 16.7%: 48.3%, WFT). High-intensity leg press exercise with 2 sets at each 8 RM, 6 RM, and 4 RM 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. RESULTS: Plasma glucose and insulin concentrations were not significantly different between KFT and WFT. Plasma creatine kinase activity at Day 5 was significantly different between KFT (213.3±26.2 U/L) and WFT (348.7±37.6 U/L) (p=.010). Resting lactate levels in KFT (1.8±0.2 mM) was significantly higher than those in WFT (1.1±0.1 mM) at Day 5 (p=.010 mM). IL-6 and cortisol levels were significantly lower in KFT (4.5±0.2 pg/mL, 447.2±26.0 ug/dL) than WFT (6.0±0.5 pg/mL, 548.4±16.9 ug/dL) at Day 5 (p=.017, IL-6; p=.006, cortisol, respectively). CONCLUSIONS: The results of the current study suggested that the KFT like the high carbohydrate meal could attenuate the muscle injury induced by high intensive resistance exercise in the comparison to high fat WFT.
