Objective:
The aim of this study was to assess the effectiveness of a workplace leg-strengthening program on self-reported function, physical capacity, and work-related outcomes among desk-based workers.
Methods:
Forty-three desk-based workers were randomized to a 12-week exercise program or no exercise control. The primary outcome was change in self-reported physical function on the Lower Extremity Functional Scale (LEFS) from baseline to follow-up. Secondary outcomes were physical capacity (mobility, strength), self-reported outcomes (pain, depressive symptoms), and work-related outcomes (resilience, work ability).
Results:
The exercise group showed greater improvements in LEFS and mobility. No significant between-group differences existed in knee strength or remaining self-reported and work-related outcomes.
Conclusion:
Workplace implemented leg-strengthening exercises are effective at improving self-reported and physical health outcomes of desk-based workers. Moving forward, occupational exercise interventions may be essential to enhance worker longevity among the aging, sedentary workforce.
