Sarcopenia, defined by low muscle mass and slow gait speed, is associated with a significantly increased risk of all-cause mortality in community-dwelling older adults.

If you are an older adult, maintaining your walking speed and muscle mass is crucial for longevity. You can assess your risk by checking if your gait speed is slower than 0.8 m/s or if you have low muscle mass. This condition, known as sarcopenia, significantly increases your risk of death, so it warrants attention and potential lifestyle interventions like resistance training.
