Effect of Exercise Type During Intentional Weight Loss on Body Composition in Older Adults with Obesity.

ABSTRACT: OBJECTIVE:To examine the long-term effects of exercise modality during weight loss on body composition and associations between body composition and physical function changes. METHODS:Two hundred forty-nine older adults (66.9?±?4.7 years, 71% women, 32% African American, BMI: 34.4?±?3.7 kg/m2 ) were randomized to weight loss (WL; n?=?82), WL plus aerobic training (WL?+?AT; n?=?86), or WL plus resistance training (WL?+?RT; n?=?81) for 18 months. Dual-energy x-ray absorptiometry-acquired body composition, 400-m walk time, and knee extensor strength were measured at baseline and at 6 and 18 months. RESULTS:Total body mass loss was enhanced when WL was combined with exercise (WL: -5.7?±?0.7 kg, WL?+?AT: -8.5?±?0.7 kg, WL?+?RT: -8.7?±?0.7 kg; P?
