Intake of carbohydrate-protein supplements by recreational users at gyms: Body composition improved?

Abstract

Summary Objectives The purpose of this study was to investigate the spontaneous use of protein and carbohydrate supplements (PCS) in amateurs practicing resistance training in gyms, and determine whether the intake of this type of supplement in practice can have beneficial effects on energy balance and body composition. Equipment and methods Sixty-seven men followed the same resistance training for 8 weeks. They were assigned to two groups: (i) 27 consuming protein and carbohydrate supplements (GC), and (ii) 40 not consuming dietary supplements (GNC). All the participants attended four experimental sessions, underwent anthropometric measurements and bioelectrical impedance analysis, and kept dietary and physical activity diaries. The GC group also recorded their spontaneous intakes of protein and carbohydrate supplements. Results Both groups significantly gained body mass (P Conclusion The spontaneous use of protein and carbohydrate supplements (PCS) by recreational users practicing resistance training at gyms induced no positive effects on body composition. We advocate more nutritional education to enhance nutritional status and learn how to use protein and carbohydrate supplements in the light of dietary needs and food intake.
