Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Humans lose muscle and strength as they get older. Further, ageing is accompanied by loss in cognitive function. It is not quite clear why this happens; however, it is known that the loss of muscle and strength can increase risk for physical and mental health risks and impair the ability of older people to remain physically independent. Weight lifting and proper nutrition, particularly eating high quality protein at the proper time and quantity, may help prevent these losses when a person gets older. To determine if regular beef consumption as part of a higher protein diet aids the muscle adaptive response to resistance training and improvements in cognition, seventy healthy individuals will be recruited to lift weights 3 times a week for 10 weeks. One group (n=36) will consume the Recommended Dietary Allowance (RDA) for protein (0.8g/kg/day), while the other group (n=36) will consume an amount twice the RDA (1.6g/kg/day), which is in agreement with recommendations from the American College of Sports Medicine. Participants will have their muscle strength tested and samples of blood and muscles will be collected before and after training to determine how the muscle adaptive response to resistance exercise is affected by higher protein intake. In addition, participants will undergo cognitive assessments at baseline and follow-up to determine the influence of improving muscle strength on attention and memory. Overall, the investigators proposed study will use sensitive methodology to determine if providing protein above the RDA and at optimal times during the day in combination with a weight lifting program can help make someone stronger and build larger muscles than someone consuming the RDA, as well as what processes may be responsible for helping the muscles to get bigger and stronger.
