Cycling at an active workstation did not impact executive function performance. However, functional near-infrared spectroscopy (fNIRS) revealed altered cortical activity, suggesting cognitive resource reallocation during cycling.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Human Physiology
Background:
- Executive functions are crucial cognitive processes.
- Active workstations offer a way to integrate physical activity with cognitive tasks.
- Understanding the impact of cycling on cognitive function is important for optimizing work environments.
Purpose of the Study:
- To investigate the effects of self-paced cycling at an active workstation on executive functions.
- To examine changes in cortical activity during cognitive tasks performed while cycling.
Main Methods:
- A crossover study design was used with 37 young adults.
- Participants completed cognitive tests (Stroop, task-switching) in both sitting and cycling conditions.
- Cortical activity was monitored using functional near-infrared spectroscopy (fNIRS).
Main Results:
- No significant differences in behavioral performance on executive function tests were found between sitting and cycling.
- Functional near-infrared spectroscopy (fNIRS) showed decreased oxygenated hemoglobin (oxy-Hb) during Stroop interference while cycling.
- Increased oxy-Hb was observed during global switch costs in the cycling condition.
Conclusions:
- Cycling at an active workstation does not impair executive function performance.
- Cognitive resources are reallocated during cycling, as indicated by changes in cortical activity patterns.
- Active workstations may offer benefits by modulating brain activity during cognitive tasks.
