Effects of a 10-week sports climbing on body composition and surrogate indices of major lifestyle disease in obese elderly women

Abstract

[Purpose] The study was designed to examine the effects of a 10-week sports climbing training on body composition and surrogate indices of major lifestyle disease in obese elderly women. [Methods] Twenty elderly women, whose percent body fat was over 35%, were randomly assigned into one of two groups, i.e., sports climbing training group (TR: n=10) and control group (CON: n=10). The subjects in TR completed sports climbing training program with 5.8 and 5.9 of difficulty, at 11-13 of ratings of perceived exertion (RPE), 60 min/session, three sessions/wk for 10 weeks. Independent variables regarding body composition and major lifestyle disease, i.e., hypertension, dyslipidemia, and atherosclerosis, were measured and compared between two groups as well as between two tests simultaneously using a repeated two-way ANOVA. [Results] Regarding physique and body composition, there were significant interactions between group and test in body weight, body mass index, fat mass, and percent body fat. These variables decreased significantly in TR. 2) Regarding indices of hypertension, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and pulse pressure decreased significantly in TR. Regarding indices of dyslipidemia, triglyceride decreased significantly in TR. Regarding indices of atherosclerosis, TG/HDL-C ratio decreased significantly in TR. [Conclusions] It was concluded that the 10-week sports climbing training would be beneficial for reduction of body fat despite its’ influence on fat-free mass was limited, and would also contribute on improving surrogate indices of hypertension, dyslipidemia, and atherosclerosis in obese elderly women. Future research investigating the effects of various period, intensity, duration, and frequency of sports climbing training would be warranted.
