The purpose of this study is to investigate any changes in body composition, such as muscle mass, %fat, and bone density, in exercise intervention according to the frequency of low-intensity aerobic exercise and resistance exercise for 16 weeks.
The subjects of the study were women aged over 75 yrs older living in Jin-gu, Busan, who were selected for sarcopenia by diagnosis of sarcopenia (ASM/weight, % ; 25.6% or less) and obesity (% fat, % ; 30% or over), Through drawing lots, a total of 104 people participated in the experiment, 29 people were eliminated from the pre-test measurement. And 29 people were excluded from the exercise intervention. The participants were randomly assigned into 5 groups; low intensity aerobic exercise 3 times per week group (n=10, 75.6±3.5 yrs), low intensity aerobic exercise 5 times per week group (n=8, 74.2±3.9 yrs), low intensity resistance exercise 3 times per week group (n=10, 75.4±3.7 yrs), low intensity resistance exercise 5 times per week group(n=8, 75.6±4.1 yrs) and a control group (n=10, 77.7±3.8 years).
For the statistical analysis, such as One-Way ANOVA, t-test, and Two-Way Repeated measures ANOVA was calculated using SPSS Version 22.0. To verify mean differences between the 5 groups, two-way repeated measures ANOVA was used.
As a result of the study, the interaction effect of the group and time period of %fat was shown (p<.05), As a result of post-verification, A5-G and R5-G were higher than CG. In the change in the main effect of the time period within the group, there was a significant decrease in A5-G (p<.001) and R5-G (p<.01). And in the change in LBM, there were no interaction effects and main effects. And the interaction effect was not shown in the change in Total BMD, but a significant decrease was shown in R3-G (p<.01) and CG (p<.05) in the change in the main effect.
Based on the research results, The interaction effect of aerobic exercise and resistance exercise 5 times a week was shown in the body fat rate change according to the low intensity form and frequency of exercise for 16 weeks in elderly women with muscle fat and bone density. However, through this study, there is a significant decrease in bone density in older women in the control group and aerobic exercise and resistance exercise group conducted three times a week, so it seems to play a role in suppressing fat and bone density due to aging.
