Association of physical activity with sarcopenia evaluated based on muscle mass and strength in older adults: 2008– 2011 and 2014−2018 Korea National Health and Nutrition Examination Surveys
Adequate physical activity (PA) is essential for preventing sarcopenia in older adults. However, there are insufficient epidemiological data on the intensity of PA needed to prevent age-related sarcopenia. The purpose of this study was to investigate the association of PA intensity with skeletal muscle mass and muscle strength.
