Background: There is a lack of quantification of occupational physical activity (OPA) and leisure time physical-activity (LTPA) among construction workers. Objectives: To describe physical activity energy expenditure (PAEE), physical workload, and the effect of a PA-intervention among construction workers. Methods: Sixty-seven Construction workers self-reported their PA, had PA assessed directly (PAEE), and observed OPA using the tool ‘Posture, Activity, Tolls and Handling’. The PA-intervention (PA;n=29,Controls;n=24) included 3x20-min training/week for 12 weeks. Results: Baseline median OPA was 5036 MET-min/week and LTPA 2842 MET-min/week, p<0.01. OPA directly recorded was (mean ±SE): 56.6±3.2 J/kg/min and LTPA was: 35.7±2.2 J/kg/min (p<0.001). Manual material handling was performed for ≥25% of working time by more than 50% of the participants. Post intervention, the training group reduced overall PAEE compared to the control group but not specifically during work. Conclusions: OPA was within the maximum recommended level of 1/3 proposed in consensus guidelines but did not decrease with PA-intervention.
