Intensity modifies the association between continuous bouts of physical activity and risk of mortality: A prospective UK Biobank cohort analysis.

ABSTRACT:

Background

Recent evidence suggests continuous bouts of physical activity (PA) are associated with longevity. We hypothesized the risk of mortality would be lower when the most active minutes of the day were in a continuous bout.

Methods

PA was assessed using accelerometery in UK Biobank participants. The intensity of the most active continuous (MX_CONT) and accumulated (MX) X min of the day, and their ratio (MX_RATIO = MX_CONT/MX), were determined. MX_RATIO indicates how the most active minutes of the day are accumulated, ranging from a single continuous bout through to sporadic accumulation spread across the day. Durations (X) considered ranged from 1 to 20 min. The outcome was mortality.

Results

In total, 94,541 participants
