Resistance exercise has been one of the major potent stimulus to the neuromuscular system Based on the specific program design resistance training has been reported to enhance shingle power, or local muscular endurance. However, the scientific basis of the exercise intensity has not been enough to manifest about several hormone(e.g. anabolic, catabolic or appetite hormone). So the purpose of this study was to define that the responses of anabolic, catabolic and appetite hormone after resistance exercise of high level intensity(HI), moderate level intensity(MI), and low level intensity(Ll). The subjects for this study were 9 men (Age=25.4±3.56yts; height=175.6±4.46㎝; weight=71.6±8.97kg) who didn’t have history of cardiopulmonary diseases and medical problem. They performed the circuit resistance training using HI(10reps at 80% of one-repetition maximum(1R14, bran rest), MI(13reps at 6O% of 1RM, Min rest), and LI(20reps; at 4O% of 1RM, 1min not) protocols with 3 sets. Approximately, total exercise volume was 39,000J on all of the exercise protocols. Hormonal concentration was measured at three different tints: pm, past and Naivety thirty minutes of the exercise. For the data, all of the measurements -tire represented by mean and standard deviation using SP% statistical package(version 10.0). The statistics techniques for data analysis were two-way repeated ANOVA to determine the differences between each intensity and each time. One-way ANOVA was used to the specific analysis of exercise intensity. The 5% level of significance was used as the critical level for acceptance of hypotheses of the study.

The purpose of this study was to investigate the correlation of peakVO2 and peakVO2 decrease factors during exercise in NIDDM group The subjects consisted 71 non-insulin dependent subjects who was aged 40-57 years were cheaked by medical process and exercise stress testing. Subjects were divided into 2 groups: male group(fasting glucose level>110[mg /㎗, n=46) and female group(fasting glucose level>110[mg/㎗], n=25). Statistical analysis was performed using analysis of independent t-test. Pervious studies have demonstrated that NIDDM group have a reduced exercise capacity compared with age-matched normal subject, the factors for this decrease in exercise capacity are still unclear, thus, this study examined potential correlates of exercise capacity such as age, diabetes duration, metabolic control and duration of hypertension, smoking habits. Results of this study were as follows. 1. Between the male and female groups %BF and BMI were showed significantly(p<0.05, p<0.01) difference, but weight was not. 2. TCH and peakRPP, peak VO2, Exercise Time were showed significantly(p0.05, p<0.01) difference, but Glucose and TG, HDL, LDL, RestSBP, RestDBP were not significantly difference between the two groups. 3. Duration of NIDDM was significantly(p<0.05/ p0.01) higher in male than female group, but duration of hypertension, duration of smoking were not significantly difference between the two groups. 4. Correlation coefficient with peakVO2 have significant(p<0.01), (p<0.05): Exercise time(r=0.828), Age(r= - 0.375), %Body Fat(r= - 0.535), Duration of NIDDM(r= - 0.333), Duration of smoking(r=- 0.652), TCH(r= - 0.280), LDL(r=-0.239). Conclusionally, It appears that Age, %Body Fat, duration of smoking, duration of NIDDM, particularly in NIDDM group, may be important in improving exercise capacity (peak VO2) and potentially improving the increased cardiovascular mortality associated with an impaired exercise capacity.
