Abstract
BACKGROUND: Sedentary work environments contribute to low physical activity (PA) levels, which are associated with adverse health and productivity outcomes. Workplace interventions such as step challenges offer a promising strategy to promote PA. AIM: This study investigates the effects of a six-week, team-based step contest conducted at a German university and examines personal and work-related factors including the role of leaders influencing PA. METHODS: A one-group pre-post design was used to assess daily step counts of 331 participants across 44 self-formed teams during baseline, intervention and follow-up periods. Step data were collected via a mobile app, and a survey captured various demographic, work-related and intervention-related factors. RESULTS: The step challenge significantly increased daily step counts by 1,700 on average compared to baseline. However, this increase was not sustained during follow-up. Males and older participants exhibited greater improvements. Notable, individuals in leadership positions showed a relatively greater increase in step counts during the intervention. However, the presence of a leader within a team did not significantly impact team colleagues' performance. Other work-related factors such as work location and commute mode correlated with participants' step counts but did not impact the step challenge's effectiveness. CONCLUSION: Our findings suggest that team-based workplace interventions can effectively boost short-term PA but sustaining these improvements remains challenging and requires ongoing actions. Further, it is essential to take personal and work-related factors including the role of leaders into account to develop targeted strategies that enhance PA. Tailored strategies and organizational support are needed to promote long-term engagement. These insights may inform future workplace health initiatives aiming for sustainable impact.
