The purpose of this study was to investigate the correlation of obesity indices and cardiorespiratory fitness and HOMA-IR and metabolic syndrome marker in college male students. A total of 85 college male students, who were apparently healthy and not taking any medications affecting blood pressure and blood lipids. Following 4h fasting, 10ml of venous blood samples were drawn from an antecubital vein into heparin-treated collection tubes for the determination of lipids and glucose levels in circulating plasma. Resting blood pressures were measured in duplicate, and mean values were used for data analyses. Cardiorespiratory fitness was quantified as maximum minute volume of oxygen consumption during a maximal treadmill exercise test using modified bruce protocol. As result, Homeostasis model assessment of insulin resistance(HOMA-IR) and cardiorespiratory fitness had not significant correlation both non-obese and obese group. Also, correlations between metabolic syndrome marker and MI and obesity indices and cardiorespiratory fitness were significant. And cardiorespiratory fitness had significant correlation with waist, HDLC, and SBP on obese group only. Finally, Predictor factor of HOMA-IR was %BF, and MI was waist by stepwise regression analysis. In conclusion, The current findings of the study suggest that both obesity and low cardiorespiratory fitness levels contribute to insulin resistance in college male students.

The purpose of the study was to examine the effect of Omija beverage ingested on blood variables, electrolyte and physical performance during the prolonged endurance exercise. Subjects were healthy and young men of college students. The subjects of present study were divided water ingestion and omija beverage ingestion group. All the experimental conditions were continued until subjects stopped because of fatigue. After endurance exercise were measured repeatedly to get results on the change of blood variables, electrolyte and exercise time for physical performance. The result of this study were as follows: 1. The blood lactate level were not significantly different at any time in each groups. However, blood glucose and insulin level were significantly different increase in Omija beverage ingestion group campared to water ingestion group(p<.05) 2. The blood Na+ concentration at immediately exercise and recovery 30 min were significantly decrease in Omija beverage ingestion group compared to water ingestion group(p<.05). However, The blood K+ and Cl+ concentration were not significantly different at any time in each groups. 3. The exhaustion period exercise time were significantly increased by omija beverage ingestion group compared to water ingestion group.(p<.05). Therefore it can the referred that the ingestion of omija beverage is valid in lengthening the exhaustion time by maintaining carbohydrate and electrolyte metabolism during endurance exercise which will not bring hypoglycemia and hyponatremia by mobilizing spare endogenous as energy source at the latter stage of endurance exercise.
