Purpose The purpose of this study was to investigate the effects of aerobic exercise intensity on body composition, health related fitness, and quality of life in elderly women. Methods 48 elderly women over 65 years of age without physical and mental problems were assigned to four groups: control group, low intensity, moderate intensity, and high intensity aerobic training group. The aerobic exercise group applied a heart rate reserve (HRR) to low-intensity group (HRR 40-55%), moderate intensity group (HRR 55-70%), high intensity group (HRR> 70%) for 12 weeks, 3 times a week for 20 minutes a day. Subjects of the control group were to maintain their usual lifestyles during the same intervention period. Body composition, health related fitness, and quality of life were measured and analyzed using repeated two-way ANOVA. Results The main results obtained in this study are as follows. 1) There was a significant decrease in sitting forward bending in the low intensity group and a significant increase in EQ-VAS. 2) There was a significant decrease in body weight, BMI, and 6 minutes walking in the moderate intensity group, and a significant increase in grip strength and EQ-VAS. 3) The high intensity group showed a significant decrease in weight, BMI, waist circumference, sitting forward bending, and 6 minutes walking, and a significant increase in grip strength, sit and stand, functional reach, and VO2max. On the other hand, there was no significant change in all variables in the control group. Conclusions In conclusion, aerobic training was found to be effective for body composition, health related fitness and quality of life in elderly women. In particular, it can be concluded that high intensity aerobic training is effective for health related fitness, and low and moderate intensity aerobic exercise is effective for improving quality of life.
