This study reaches a conclusion as follows by analyzing two groups of body compositions and lipid levels of forties and fifties women who exercised for 12 weeks. One group was done complex training of weight training and aerobic training and the other group conducted circuit weight training.
First, complex training group shows decrease of a rate and an amount of body-fat statistically. Circuit training shows decrease of a rate and an amount of body-fat statistically. Body compositions of before and after exercising don't statistically show difference between groups in a rate of fat, amount of fat and LBM(Lean Body Mass).
Second, the lipid of complex training group statistically increased in HDL-C, LDL-C, TG, and TC. The lipid of circuit weight training statistically increased in LDL-C and TG. Body-fats before and after training in two groups show the difference only in TC.
To sum up, complex training for 12 weeks has effect on a rate and an amount of fat, HDL-C, LDL-C, TG and TC. Circuit training has effect on a rate and an amount of fat, LDL-C and TG.
However, the changes between groups indicate that complex training is more effective than circuit training. Therefore, It is considered that complex training of weight training and aerobic training is more effective to forties and fifties women.
