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 .
Walks4Work: assessing the role of the natural environment in a workplace physical activity intervention.
OBJECTIVES The primary aim of this study was to examine the impact of  physical activity ( PA ) in the natural environment ( eg , " green exercise " ) on resting autonomic function in the Walks4Work intervention . A secondary aim was to assess the feasibility of Walks4Work in terms of adherence , change in PA levels , and cardiovascular health parameters . METHODS In an 8-week r and omized control trial , 94 office workers in an international company were allocated to one of three groups : control , nature ( NW ) , or built ( BW ) lunchtime walking route . Both walking groups were required to undertake two lunchtime walks each week . The NW route centered around trees , maintained grass , and public footpaths . In contrast , the BW consisted of pavement routes through housing estates and industrial areas . Data were collected at baseline and following the intervention . To investigate the impact of the intervention , mixed- design analysis of variance ( ANOVA ) were performed . RESULTS A total of 73 participants completed the intervention ( drop-out rate of 22 % ) . No difference was observed in resting autonomic function between the groups . Self-reported mental health improved for the NW group only . PA levels increased at the intervention mid-point for all groups combined but adherence to the intervention was low with rates of 42 % and 43 % within the BW and NW groups , respectively . CONCLUSION Accompanying a guideline of two active lunchtimes per week with low facilitator input appears inadequate for increasing the number of active lunchtimes and modifying cardiovascular health parameters in an office population . However , this population fell within normal ranges for cardiovascular measures and future research should consider investigating at-risk population s , particularly hypertensive individuals
