Effects of Whey Protein Supplementation Pre- or Post-Resistance Training on Muscle Mass, Muscular Strength, and Functional Capacity in Pre-Conditioned Older Women: A Randomized Clinical Trial.
Study Goal
The researchers aimed to investigate the effects of whey protein supplementation consumed either immediately before or after resistance training on skeletal muscle mass, muscular strength, and functional capacity in pre-conditioned older women.
Results Summary
The study found that resistance training combined with whey protein supplementation (either pre- or post-exercise) improved skeletal muscle mass, muscular strength, and functional capacity in older women, though the abstract does not specify the magnitude or statistical significance of these effects.
Population
Pre-conditioned older women (70 participants).

Aging is associated with sarcopenia and dynapenia, with both processes contributing to functional dependence and mortality in older adults. Resistance training (RT) and increased protein intake are strategies that may contribute to health improvements in older adults. Therefore, the aim was to investigate the effects of whey protein (WP) supplementation consumed either immediately pre- or post-RT on skeletal muscle mass (SMM), muscular strength, and functional capacity in pre-conditioned older women. Seventy older women participated in this investigation and were randomly assigned to one of three groups: whey protein pre-RT and placebo post-RT (WP-PLA,
