As men age, muscle loss commonly occurs, and is a symptom of andropause. Male muscle loss manifests itself both as the loss of muscle strength and of overall muscle mass.
Age related muscle loss -- sarcopenia -- can begin as early as a man's mid-20's, but is most pronounced after age 60.
Studies have shown that between the ages of 25 and 60, a physically inactive male will lose muscle mass and strength at a rate of .5% annually. Although this may seem like a small amount, it quickly adds up!
Unfortunately, this process accelerates as the man continues to grow older, with male muscle loss doubling to about 1% annually after age 60, and 2% annually after age 70.
