Bidirectional association of daily steps with sarcopenia: a longitudinal study.

ABSTRACT: Step count is a well-established measure of physical activity, and step-based recommendations offering practical public guidance. However, the bidirectional associations between step count and sarcopenia remain unclear, limiting the application of step-based interventions for sarcopenia prevention.
