How does aging generally impact muscle mass and strength?

As individuals age, a common physiological change is the loss of muscle mass and strength, a process known as sarcopenia. This condition typically begins around the age of 30 and can lead to a significant decrease in both muscle size and function over time. The decline in muscle mass occurs due to various factors such as hormonal changes, sedentary lifestyle, and the body's reduced ability to synthesize protein effectively. This loss of muscle not only affects strength but also impacts overall physical performance, balance, and the risk of injury.

Understanding this process is crucial, especially for personal trainers working with aging populations. By focusing on resistance training and other forms of physical activity, trainers can help mitigate the effects of sarcopenia, promoting better health and functionality in their clients as they age.
