The Effects of Long-Term Training of Aerobic Exercise on Some Risk Factors of Cardiovascular Disease

25 males, aged 40-60 years, who participated in aerobic-type exercise on moderate intensity(60~85% of MHR), 3~5 days a week for 6~12 months were selected. Data were obtained at pre- and post-participation of tranining period for height, weight, girths of chest and abdomen, body fat, BP, HR, serum cholesterol, triglyceride, HDL-cholesterol, glucose, uric acid, BP and HR during graded treadmil exercise, and VO₂max.

After training for average 38.4 weeks, significant reductions occured in percent of body fat, HR and SBP both at rest and exercise, triglyceride, but not in cholesterol, LDL-cholesterol. And DBP, HDL-cholesterol were elevated. VO₂max was increased apparantly by 16.4%.

From the results was concluded that training of aerobic exercise could reduce the risk of coronary heart disease by 1) decreasing myocaridal oxygen demand, 2) improving on lipid profile, 3) increasing cardiac work capacity.
