The purpose of this study was to investigate the effects of two exercise program(circuit training and aerobic exercise) on weight, %fat, metabolic syndrome risk factors(waist measurement, SBP, DBP, TG, HDL-C, glucose), arteriosclerosis index(TC/HDL-C, TG/HDL-C, LDL-C/HDL-C), blood vessel inflammation markers(IL-6, TNF-α, CRP, WBC, adiponectin) in middle -aged obesity women. The subjects participated for this study were twenty four obese women(%fat: over 30%, age: 40 middle aged women), and then they were divided into three group: circuit training group(n=8), aerobic exercise group(n=8), control group(n=8). Aerobic exercise was composed of treadmill, cycle ergometer, ellipse instructions. Circuit training was composed of aerobic exercise and muscle resistance exercise, which was consisted of total 10 stations(respectively 5 stations, rest for 2min per 1set). All exercise programs was performed at the level of HRmax 50-85%, for 4-5 days(less than 60min) per week over a period of 12 weeks. Both prior to and after the 12-week exercise programs, anthropometric variables and metabolic syndrome factors (i.e., body weight, %fat, waist measurement, SBP, DBP) were measured to be analyzed, and then, the arteriosclerosis index(TC/HDL-C, TG/HDL-C, LDL-C/HDL-C) and the blood vessel inflammation markers(i.e., IL-6, TNF-α, CRP, WBC, adiponectin) were measured in fasting venous blood samples. All data were analyzed by repeated two-way analysis of variance.
The results were as follows:
1. The change of weight and %fat
The weight and %fat of aerobic exercise group and the circuit training group were decreased after treatment then before treatment, but the weight and %fat of the control group had no differences between treatments.
2. The changes of the metabolic syndrome risk factor
The waist measurement, SBP of the aerobic exercise group and the circuit training group were decreased after treatment then before treatment, but the waist measurement, SBP of the control group had no difference between treatment., The HDL-C of the aerobic excise group and the circuit training group were increased after treatment then before treatment, but there was no difference in HDL-C of the control group. There was no difference between group and treatment in TG.
3. The changes of the arteriosclerosis index
The T-CHL/HDL-C and LDL-C/HDL-C of the aerobic exercise group and the circuit training group were decreased after treatment then before treatment, but the T-CHL/HDL-C and LDL-C/HDL-C of the control group had no differences between treatments. The TG/HDL-C was no difference among group, but the TG/HDL-C was decreased after treatment then before treatment.
4. The changes of the blood vessel inflammation markers
The IL-6 of the aerobic exercise group and the circuit training group were decreased after treatment then before treatment, but the IL-6 of the control group had no differences between treatments. The TNF-α and the CRP were no difference between group and treatment. The adiponectin were no difference among the group, but the adiponectin was increased after treatment then before treatment. The WBC of the aerobic exercise group and circuit training group were decreased then those of the control group. And there was lower after treatment then before treatment in WBC.
Consequently, the circuit training and the aerobic exercise for 12 weeks were appeared to have the positive influence on the metabolic syndrome risk factors and the factors of the arteriosclerosis index for the middle-aged obesity women. And the decrease of IL-6 and WBC being secreted at obesity cells from weight decrease by exercise andthe increase of adiponectin may restrict the occurrence of inflammation of obesity patient. But the further studies were seemed to be required as to whether the circuit training and the aerobic exercise influenced on the changes of TNF-αand CRP. And as the difference between the circuit training and the aerobic exercise in most dependant variables were not found, the relevant continuous studies may be required.
