The main way to assess healthy muscle aging is through tests of muscle strength and physical performance. Some common tests include grip strength, gait speed, the chair stand test, and the timed-up-and-go (TUG) test. Secondarily, body composition may be assessed using tools such as dual-energy X-ray absorptiometry (DXA) or bioelectrical impedance analysis (BIA).
