Intra-individual and inter-individual variability in daily sitting time and MVPA.

ABSTRACT:

Objectives

Little is known about how much variability exists in free-living sitting time within individuals. The purpose of this study was to examine intra-individual variability of objectively determined daily sitting time and to determine if this variability was related to weekly averages of sitting duration or recommended moderate-vigorous physical activity (MVPA). Also, this study determined the reliability of free-living sitting and MVPA time as it useful for guiding researchers in determining how many days of monitoring are needed.

Design

An activPAL monitor was worn for 7 consecutive days by 68 women (52±8 years).

Methods

Intra-individual range of daily sitting time was calculated. Generalizability theory analysis determined the reliability of daily sitting and
