Fitness, Strength and Body Composition during Weight Loss in Women with Clinically Severe Obesity: A Randomised Clinical Trial.

ABSTRACT:

Introduction

To determine whether combined exercise training with an energy-restricted diet leads to improved physical fitness and body composition when compared to energy restriction alone in free-living premenopausal women with clinically severe obesity.

Methods

Sixty premenopausal women (BMI of 40.4 ± 6.7) were randomised to energy restriction only (ER) or to exercise plus energy restriction (EXER) for 12 months. Body composition and fitness were measured at baseline, 3, 6 and 12 months.

Results

VO2 peak improved more for EXER compared to ER at 3 (mean difference ± SEM 2.5 ± 0.9 mL ∙ kg-1 ∙ min-1, p = 0.006) and 6 (3.1 ± 1.2 mL ∙ kg-1 ∙ min-1, p = 0.007) but not 12 months (2.3 ± 1.6 mL ∙ kg-1 ∙ min-1, p = 0.15). Muscle strength improved more for EXER compared to ER
