the effects of concurrent training on the body composition, quality of life, and sleep quality of postmenopausal women with breast cancer

Background: concurrent training is more effective in developing fitness indicators than doing endurance and resistance training separately. however, there has been limited research to evaluate the effects of this type of exercise training on improvement of body composition and quality of life indicators in postmenopausal women with cancer. objectives: the present study aimed to determine the effects of eightweek of concurrent training on body composition, quality of life, and sleep quality in postmenopausal women with breast cancer.methods: this study was conducted on 42 women with breast cancer who were selected randomly and divided into exercise training and control groups. the training group followed eightweek of resistance training (2 3 sets, 10 18 repetitions, and 50% 70% 1rm) and aerobic training (50% 70% maximum heart rate, 12 14 borg scale, and 20 40 minutes). anthropometric characteristics were measured based on body composition (zeus 9.9), the sleep quality was measured by the pittsburgh sleep quality index (psqi), and the quality of life was measured by the mcgill quality of life (mqol) questionnaire. twoway repeated measures anova has been used for mcgill’s analysis of variance (p < 0.05).results: the results showed a significant decrease in sleep quality score, weight, fat percentage, bmi, and waist circumference in the training group (p < 0.05), as well as an increase in quality of life index in the training group (p < 0.05). however, no significant changes were observed in the waisthip ratio (whr) values of the training group compared with the control group (p > 0.05). conclusions: although the changes in whr index were not significant after eight weeks of concurrent training, this type of training program could be considered as a beneficial way for improving body composition, quality of life, and sleep quality in patients with breast cancer.
