PURPOSE: This study is to investigate the effects of combined exercise on body composition, physical fitness and leukocyte telomerelength in elderly women. METHODS: Twenty-six elderly women were randomly divided into two group: combined exercise group (EXE, n=14) and controlgroup (CON, n=12). EXE group performed combined exercise for 60 mintues per day, 2days/week for 12 weeks. RESULTS: There was significant interaction between groups and time points in body composition (e.g., skeletal muscle mass, visceral fatarea, and Inbody score). EXE group was no significant changes in skeletal muscle mass, visceral fat area and Inbody score, but the CONgroup showed significant decrease in skeletal muscle mass and Inbody score. Furthermore, increased in visceral fat area. Among themeasurement variable of physical fitness, there was significant interaction between group and time in 6 minutes walking test, chair sittest, and knee flexion muscle endurance. In EXE group, 6 minutes walking test and chair test was significantly increased, and therewere no significant differences in knee flexion muscle endurance, whereas CON group, the 6 minutes walking test and knee flexionmuscle endurance significantly decreased, and there was no significant difference in chair test. In addition, there was significant interactionbetween groups and time points in leukocyte telomere length. EXE group was no significant changes, but CON group significantlydecreased. CONCLUSIONS: Our study suggest that combined exercise-induced improvement of body composition and physical fitness may havehad a positive effect on leukocyte telomere length in elderly women.
