Six Weeks of Moderate Functional Resistance Training Increases Basal Metabolic Rate in Sedentary Adult Women

摘要

International Journal of Exercise Science 11(2): 32-41, 2018. Basal metabolic rate (BMR) is a significant contributor to total daily energy expenditure. Traditional resistance exercise has been shown to elicit fat free mass (FFM) related increases in BMR. The purpose of this study was to examine the effect of a functional resistance exercise program on the BMR of a group of previously sedentary adult women in a free-living condition. 19 sedentary, apparently healthy women underwent body composition analysis and had BMR assessed before and after a 6-week functional resistance training program. The resistance training program was designed to be progressive in volume and intensity, and to be achievable for novice exercisers. Following exercise training, BMR significantly increased (+246.76Kcal*day-1 ± 231.48, t=4.64, p .05). There was also a modest increase in total mass (+0.63 ± 0.87 Kg t=3.16, p=.005). Results from this study suggest that 6 weeks of functional, progressive, resistance exercise can elicit significant improvements in BMR in previously sedentary adult women; but does not elicit significant changes in body composition, FFM, or FM.
