A 12-week Texas A&M trial in adults aged 45 to 65 found that daily creatine added lean tissue and strength, with or without a structured exercise program.
Sarcopenia, the loss of muscle mass with age, can start as early as one’s 30s, and affects a large proportion of the elderly. Fortunately, exercise can combat muscle aging, likely by reversing many of the age-related physiological changes at the... Continue Reading →
In space, the human body loses muscle mass. Although living in microgravity requires no heavy lifting, this loss of muscle reduces physical performance. Decreased muscle mass could also prove particularly problematic on future missions to destinations such as the Moon... Continue Reading →
