We read with great interest the article by Nakakubo et al. [1], which examined the association between long sleep duration and sarcopenia according to objectively measured physical activity among community-dwelling older adults.The authors should be commended for combining accelerometer-derived moderate-to-vigorous physical activity (MVPA) with multidimensional sarcopenia assessment.Their finding that long sleep duration was associated with sarcopenia among participants with lower MVPA, but not among those with higher MVPA, provides a clinically relevant basis for integrating sleep and movement behaviors into geriatric rehabilitation.However, three issues merit further consideration before these findings are applied in practice.
