Physical fitness is associated with fat mass and muscle mass in Chinese preschoolers
Published 2025-07-01“…The results also revealed that both fat and muscle mass indices are dependent on changes of physical fitness ability except for balance among preschool children. Multiple linear regression analysis also identified significant positive associations between muscle mass indices and physical fitness parameters (handgrip, standing long jump, 4 × 10m shuttle run, and PREFIT 20m shuttle run), while significant negative associations were observed between these fitness measures and fat mass indices. …”
