Combined resistance exercise and essential amino acid intake enhance follistatin/myostatin ratio and muscle fitness in older women: a randomized controlled trial

Key Points

• To investigate the effects of combined resistance exercise and essential amino acid intake on muscle fitness in older women.
• Conducted a randomized controlled trial
• Intervened with resistance exercise and essential amino acid supplementation
• Measured follistatin and myostatin levels to assess muscle growth
• Increased follistatin/myostatin ratio observed
• Improvement in muscle fitness metrics noted in participants
• Participants reported enhanced strength and endurance
