ABSTRACT

Kim, H.J., Kim, C.K. Effects of one year exercise training program on the impaired fasting glucose, cardiovascular risk factors and aerobic exercise capacity in middle aged men. Exercise Science, 14(2): 203-214, 2005. This study was performed to investigate the effect of one year exercise training on cardiovascular risk factors, blood glucose and aerobic exercise capacity in middle aged men with impaired fasting glucose level. The subjects (90 males, 41 - 57 years) were divided to Control (n=32), Normal (training, n=40), and IFG (impaired fasting glucose concentration, n=18) group according to the presence of training or IFG. Waist circumference, blood pressure, fasting glucose, triglyceride, HDL-cholesterol, VO2max (maximal oxygen uptake), AT (anaerobic threshold) and HRmax were measured at baseline and after one year of exercise training. Aerobic exercise training consisted of treadmill running at 60-70% of VO2max (30 minutesㆍday-1, 3 daysㆍweek-1) and resistance training performed three sets of lifts using 60-70% of 1RM to complete each of 8 rpt/set (3 daysㆍweek-1) during one year. Waist circumference, triglyceride, HDL-cholesterol, VO2max, AT in Training group (Normal and IGT group) were changed significantly by training (p<.05) and there was no differences of training effect between those two groups. But, all cardiovascular risk factors and aerobic exercise capacity in Control group were unchanged after one year. On the other hands, there were significant negative correlation between aerobic capacity and cardiovascular risk factors (waist, blood pressure, and triglyceride, p<.05). These results support that long term exercise training program combined aerobic and resistance training can be effective regimen to prevent cardiovascular disease in middle aged men with impaired fasting glucose.

Key words: cardiovascular risk factor, aerobic training, resistance training, impaired fasting glucose
