Objective

Characterize the number of minutes of moderate and vigorous physical activity at work and outside of work during seven consecutive days, in a sample of 55 commercial construction workers.

Methods

Workers wore accelerometers during work and outside work hours for seven consecutive days, and completed brief survey at the seventh day of data collection.

Results

From the directly measured physical activity, the average number per participant of moderate minutes of occupational physical activity and physical activity outside of work obtained in short bouts were 243 minutes (65%) and 130 minutes (35%), respectively. Directly measured minutes of vigorous occupational physical activity were significant and positively correlated with self-reported fatigue.

Conclusions

Among commercial construction workers, physical activity from work contributes significantly, approximately 2/3, towards a workers total amount of weekly minutes of moderate physical activity.
