About our methodology →Introduction
Aging can lead to muscle loss and weakness, which can negatively impact the quality of life of older adults. Recently, a study published in the PubMed database found that combining resistance exercise with essential amino acid supplementation can be an effective strategy for improving the follistatin/myostatin ratio and muscle fitness in older women.
Method
The study was a randomized controlled trial that included 30 older women who were randomly assigned to one of two groups: a resistance exercise group with essential amino acid supplementation or a control group. The participants in the resistance exercise group performed resistance exercises twice a week for 12 weeks, and also received daily essential amino acid supplementation. The participants in the control group received no intervention.
Results
After 12 weeks, the participants in the resistance exercise group with essential amino acid supplementation showed significant improvements in the follistatin/myostatin ratio and muscle fitness compared to the participants in the control group. Additionally, the participants in the resistance exercise group also showed improvements in physical function and quality of life.
Discussion
The results of this study suggest that combining resistance exercise with essential amino acid supplementation can be an effective strategy for improving the follistatin/myostatin ratio and muscle fitness in older women. The follistatin/myostatin ratio is important because myostatin is a protein that inhibits muscle growth, while follistatin is a protein that promotes muscle growth. Therefore, a higher follistatin/myostatin ratio can be beneficial for muscle health.
