Effects of Resistance Training and Supplementation in Elderly: Cardiorespiratory and Metabolic Variables
Sponsor: Federal University of São Paulo
Summary
Aging causes losses in strength, lean mass, and cardiovascular health in the elderly due to metabolic changes and alterations in body composition. To investigate whether nutritional interventions and physical training can mitigate these effects, a randomized clinical trial will be conducted at the Evangelical University of Goiás with elderly individuals aged 60 to 85. Participants will be divided into four groups: control, protein supplementation, physical training, and a combination of both. The study will last for 12 months, with evaluations every four months, covering cardiovascular, pulmonary, immunological, renal, muscular, and hematological parameters. The analyses will seek statistical significance, and it is expected that the interventions will significantly improve the participants\' health.

Interventions
Whey protein supplementation.
Protein supplementation will be provided through isolated whey protein, commonly known as whey protein isolate, which was generously donated by the Heroes Science Institute (HSI), as stated in the attached declaration. This whey protein isolate, with a vanilla flavor, is packaged in 25-gram sachets, each providing a total of 20 grams of protein per dose/sachet.
Resistance training
The resistance training protocol in the study included seven exercises: high pull, leg extension, leg curl, bicep curl, triceps pushdown, lateral raise, and machine bench press, taking about 60 minutes per session. The first week focused on familiarizing participants with the exercises to ensure proper execution before intensive training began. Training occurred three times a week for 12 weeks, with each exercise performed in 3 sets of 8 to 12 repetitions and rest periods of 1 to 2 minutes. The load was progressively increased by 2% to 10% weekly, based on participants\' ability to complete repetitions with full range of motion. Assessments were conducted before training and 24 hours after the final session to evaluate the effects on physical and functional parameters.
Group Control
The control group will not participate in any of the interventions proposed in the study, meaning it will not receive supplementation or undergo resistance training, serving as a reference to compare the results of the other intervention groups.
