Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to explore the impact of a 15-minute exercise break on brain function and cognitive performance in a simulated classroom setting. The main questions it aims to answer are:

1. How do short exercise breaks affect executive function in college students?
2. What changes occur in brain connectivity and microcirculation after these exercise breaks? Participants were college students who engaged in sessions of continuous sitting or sitting interspersed with exercise. The study used cognitive tasks and brain imaging techniques to measure the effects. The findings reveal improvements in cognitive performance and brain function, suggesting that short exercise breaks are beneficial in educational contexts.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The study used a within-participant cross-over design with pre-and post-test comparisons. Participants completed the three following experimental conditions in pseudo-counterbalanced (cannot be completely counterbalanced given that an odd number of participants - hence, was pseudo-counterbalanced) order (odd number of participants) with at least a 7-day washout period between conditions: (i) 115-minute uninterrupted sitting \[control\]; (ii) 50-minute sitting + 15-minute moderate-intensity cycling + 50-minute sitting \[experimental condition 1\]; (iii) 50-minute sitting + 15-minute vigorous-intensity cycling + 50-minute sitting \[experimental condition 2\]. A familiarization session was completed about three days before the experiment started, during which participants were familiarized with the cognitive assessment and cycling protocols.
