Resistance training preserves fat-free mass without impacting changes in protein metabolism after weight loss in older women.

ABSTRACT: This study assessed the effects of resistance training (RT) on energy restriction-induced changes in body composition, protein metabolism, and the fractional synthesis rate of mixed muscle proteins (FSRm) in postmenopausal, overweight women. Sixteen women (age 68 +/- 1 years, BMI 29 +/- 1 kg/m(2), mean +/- s.e.m.) completed a 16-week controlled diet study. Each woman consumed 1.0 g protein/kg/day. At baseline (weeks B1-B3) and poststudy (weeks RT12-RT13), energy intake matched each subject's need and during weeks RT1-RT11 was hypoenergetic by 2,092 kJ/day (500 kcal/day). From weeks RT1 to RT13, eight women performed RT 3 day/week (RT group) and eight women remained sedentary (SED group). RT did not influence the energy restriction-induced decrease in body mass (SED -5.8 +/- 0.6 kg; RT -5.0
