Whey Protein Supplementation Associated With Resistance Training on Health Indicators in Trained Older Women

Summary

The main purpose of the present study was to investigate the effects of whey protein supplementation associated with resistance training on muscle strength, body composition, muscle quality, cellular hydration, cardiometabolic risk factors, inflammatory and oxidative stress markers in trained elderly women and to evaluate whether the timing of protein intake provide different responses on these variables.

Interventions

DIETARY_SUPPLEMENT

Whey protein-placebo

This investigation was carried out over a period of 26 weeks divided in two phases. The first phase of the study was an eight-week period (weeks 3-10), during which subjects were familiarized to RT. Phase 2, supplementation phase, the participants was randomized in three groups and started 12 weeks dedicated to supplementation plus RT (weeks 13-24). At the beginning and the end of each phase of the experiment, two weeks were allocated for evaluations (weeks 1-2, 11-12 and 25-26) consisting of anthropometric, body composition, blood samples, blood pressure, one repetition maximum tests (1RM) and dietary intake measurements
