PurposeDespite preventive efforts from some companies to offer some sport and physical activity (SPA) to their employees, French participation rates remain very low, which limit impacts in terms of health and economic benefits. The aim of this study was to better understand the factors influencing SPA participation in the workplace.Design/methodology/approachA cross-sectional study was conducted based on an electronic questionnaire survey disseminated to 24 companies based in France that offered SPA to their employees. An independent sample t-test was conducted to explore the differences between the most common facilitating and constraining factors, in relation to “being a sporty person” self-perception, leisure-time physical activity (LTPA) level and demographic information. Predictors of SPA in the workplace were determined using a binomial logistic regression.FindingsA total of 1,318 employees completed the survey, of which 60% were women, mostly highly educated and white collar. “Being a sporty person,” self-perception has been a predictor of SPA participation in the workplace.Practical implicationsMore multicomponent work-based interventions, including incidental physical activity, might be necessary to increase participation and overcome time constraint.Originality/valueAlthough SPA participation in the workplace is considered to promote numerous positive organizational and individual consequences, this is the first study to assess the associations between facilitating and constraining factors of SPA participation in the workplace setting and physical self-perception.
