The purpose of this study is to examine the change in body
composition, blood pressure and physical fitness in elderly women, living in S city, J province. 40 women are selected as exercise group(EG,
n=20) and comparison group(CG, n=20). Exercise group have carried the circuit exercise program three times a week for 12 weeks as the level of 60~80% of aerobic exercise capacity.
All the data calculated the average and standard deviation, and SPSS program was used to examining the differences in experiments, and they
are measured repeatedly for the interaction effects between the group and period ANOVA. Paired t-test was performed to verified the changes before and after within the group and independent t-test was performed
to test the significant levels of differences between the group.
As the result of this study of the 12 weeks circuit exercise program,
we obtained the following conclusions.
First, circuit exercise group are significantly improved in body composition factors, such as body weight(P<.01), body fat percentage(P<.001) and waist circumference(P<.001). Second, circuit exercise group are significantly improved in blood
pressure factors, such as SBP(P<.001), DBP(P<.01) and PP(P<.05).
Third, the circuit exercise group showed significant improvements on physical fitness factors, such as lower limb function(P<.05),
cardiovascular endurance(P<.05), flexibility(P<.001) and left foot balance(P<.01). Circuit exercise group showed a significant improvement on muscular strength(P<.01), dynamic balance(P<.01) and
coordination capability(P<.05). However, there was no significant change in other physical fitness factors except the improvement on the
dynamic balance(P<.001) in comparison group.
To summarize the above results, 12 week circuit exercise induced significant improvements on body composition, blood pressure and
physical fitness levels in elderly women. These results suggest that circuit exercise which is a mixture of aerobic exercise and resistance
exercise can have a positive effect on the prevention, management or treatment of obesity, chronic disease in elderly women. In addition to improving overall physical fitness levels, it has a positive impact on the vitality and viability in elderly women
