Duration of moderate to vigorous daily activity is negatively associated with slow walking speed independently from step counts in elderly women aged 75 years or over: A cross-sectional study

摘要

Objectives: This study aimed 1) to examine whether objectively measured duration of moderate to vigorous physical activity (MVPA) was associated with slow walking speed, independent from step counts, in elderly women aged 75 or over (old-old) and 2) to determine a possible cut-off value for duration of MVPA related to slow walking speed.
