The Influence of Workplace-Integrated Exercise Snacks on Cognitive Performance in Sedentary Middle-Aged Adults-A...

Area of Science:

• Exercise science
• Cognitive neuroscience
• Occupational health

Background:

• Sedentary behavior is a known risk factor for cognitive decline.
• Workplace interventions are needed to mitigate sedentary risks.

Purpose of the Study:

• To investigate the acute and chronic effects of workplace-integrated exercise snacks on cognitive performance.
• To assess the impact of short, vigorous exercise bouts on executive functions in middle-aged office workers.

Main Methods:

• Pilot study with 25 sedentary office workers (aged 51.4 ± 5.3 years).
• Intervention group (n=12) performed three 1-minute vigorous exercise bouts daily, 4 days/week for 4 weeks.
• Control group (n=13) maintained usual routine. Cognitive tests (Trail Making Test, Stroop Color-Word Test) assessed pre-, acute-, and post-intervention effects.

Main Results:

• Significant immediate improvements in cognitive performance after a single exercise bout (p ≤ 0.05).
• Sustained cognitive benefits observed after four weeks of intervention (p ≤ 0.05 interaction effects).

Conclusions:

• Workplace exercise snacks can provide both immediate and lasting enhancements in executive functions.
• Incorporating brief, vigorous exercise into sedentary work environments shows potential for improving cognitive health.
