Conclusions Workplace-based physical activity interventions consisting of at least moderate-intensity activity improve cardiorespiratory fitness .
At the present time , we surmise that no single group of employees ( e.g. older employees or less fit individuals ) can be definitively identified as st and ing to benefit more from workplace physical activity interventions than others .
This demonstrates the potential utility of workplace physical activity interventions for improving cardiorespiratory fitness in a broad range of healthy employees .
Background Cardiorespiratory fitness is a strong predictor of all-cause mortality .
Physical activity of at least moderate intensity can improve cardiorespiratory fitness .
Workplaces may provide a relatively controlled setting in which to improve cardiorespiratory fitness through physical activity .
Limited work has been conducted to quantify the impact of delivering physical activity in the workplace on cardiorespiratory fitness .
Objective The objective of this systematic review was to quantify the effects of workplace physical activity interventions on peak oxygen consumption ( VO2peak ) and explore study and participant characteristics as putative moderators .
Randomised controlled trials – the gold standard for effectiveness research
Learning points R and omised controlled trials ( RCTs ) are the reference st and ard for study ing causal relationships between interventions and outcomes as r and omisation eliminates much of the bias inherent with other study design s. To provide a true , reliable assessment of effectiveness , RCTs need to be conducted robustly , i.e. with concealment of allocation , blinding , intention-to-treat analysis and sufficiently large sample size
