NCT06880211

Brief Summary

The ActivitySnippets study will investigate the effects of short activity snippets on the sedentary behavior of bus and tram drivers. The main research question is: Do activity snippets increase the amount of time bus and tram drivers spend in a physically active state and reduce the amount of sedentary time during working hours? This research question will be investigated with a randomized controlled trial.

Outcome Measures

Primary Outcomes (1)

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on the physical activity behavior compared to general physical activity recommendations.

    Physical activity behavior will be quantified with the MATRIX ACTIVITY MONITOR, an activity tracker from Parmay Tech. This tracker will investigate the physical activity behavior for 7 days at each time point.

    From enrollment to the end of the 16 weeks intervention phase.

Secondary Outcomes (8)

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on daily steps compared to general physical activity recommendations.

    From enrollment to the end of the 16 weeks intervention phase.

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on muscular strength compared to general physical activity recommendations.

    From enrollment to the end of the 16 weeks intervention phase.

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on flexibility compared to general physical activity recommendations.

    From enrollment to the end of the 16 weeks intervention phase.

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on perceived stress compared to general physical activity recommendations.

    From enrollment to the end of the 16 weeks intervention phase.

  • The additional effect of short activity snippets, integrated into the daily work routine of bus and tram drivers, on helth-related quality of life compared to general physical activity recommendations.

    From enrollment to the end of the 16 weeks intervention phase.

Study Arms (2)

physical activity recommendations

ACTIVE COMPARATOR

The control group will receive the latest World Health Organization recommendations for physical activity for 16 weeks.

Other: physical activity recommendations

activitysnippets

EXPERIMENTAL

The intervention group will receive a set of activity snippets for 16 weeks, consisting of a series of short exercises designed to improve muscle strength, increase physical activity levels at work and reduce stress.

Other: activitysnippets

Interventions

The participants (bus and tram drivers) in the control group will receive the latest World Health Organization recommendations for physical activity in written form.

physical activity recommendations

Participants (bus and tram drivers) in the intervention group will receive the ActivitySnippets toolbox. The toolbox was developed through collaborative workshops with the target group, sports scientists and physiotherapists to create a sustainable, occupation-specific and evidence-based physical activity promotion. The toolbox, which provides simple incentives to integrate physical activity into everyday working life, consists of 30 to 40 activity snippets (exercise cards). The design of the toolbox allows for individualization and variation of the exercise cards. The aim of the exercises is to improve muscle strength, increase physical activity levels at work and reduce stress. All exercises can be performed for between 10 and 60 seconds, allowing for realistic implementation in everyday working life. Participants are encouraged to incorporate the exercises into their daily work routine as often as possible.
