Dragon boat exercise reshapes the temporal-spatial dynamics of the brain

Area of Science:

• Neuroscience
• Exercise Physiology
• Sports Science

Background:

• Exercise training is known to improve neurological function.
• Research on exercise's impact on functional brain network spatiotemporal synchronization is limited.
• Understanding these dynamics is crucial for neurological health.

Purpose of the Study:

• To investigate how dragon boat exercise training affects the spatiotemporal synchronization properties of functional brain networks.
• To compare brain activity and complexity between professional and amateur dragon boat racers.
• To provide evidence for exercise-induced improvements in cerebral functional network efficiency.

Main Methods:

• Recruited 23 professional and 24 amateur dragon boat racers.
• Recorded electroencephalography (EEG) during simulated paddling on ergometers.
• Analyzed spatiotemporal brain dynamics using microstates and omega complexity.

Main Results:

• Professional racers exhibited significantly altered temporal dynamics in microstate D (attentional networks), with increased duration, occurrence, and coverage.
• Transition probabilities of microstate D were also significantly different between groups.
• Professional racers showed lower brain complexity, indicated by a significant decrease in omega complexity in the alpha and beta frequency bands.

Conclusions:

• Dragon boat training appears to strengthen the brain's attentional networks.
• This training may lead to reduced overall brain complexity, suggesting increased efficiency.
• The study provides evidence that dragon boat exercise enhances cerebral functional network efficiency on a spatiotemporal scale.
