Summary
This summary is machine-generated.World-class gymnasts exhibit reduced brain network flexibility due to intensive training. This neuroplasticity, observed in motor and cognitive networks, suggests altered brain dynamics in highly skilled athletes.
Area Of Science
- Neuroscience
- Sports Science
- Network Science
Background
- Intensive training induces neuroplasticity and optimized brain modularity in elite athletes.
- Previous research often assumes static brain networks, overlooking dynamic changes over time.
Purpose Of The Study
- To investigate the impact of long-term intensive training on dynamic functional brain network properties in gymnasts.
- To analyze changes in brain modularity and temporal dynamics using a multilayer network model.
Main Methods
- Collected resting-state functional MRI data from 13 gymnasts and 14 controls.
- Constructed dynamic functional connectivity matrices and applied multilayer community detection.
- Calculated graph theoretical parameters (flexibility, cohesion, etc.) to characterize network dynamics.
Main Results
- Gymnasts displayed significantly lower global flexibility, cohesion, and disjointedness compared to controls.
- Reduced flexibility and cohesion were observed in auditory, sensorimotor, and default mode networks in gymnasts.
- Decreased flexibility and cohesion were prominent in motor function-associated brain regions for gymnasts.
Conclusions
- Long-term intensive training in gymnasts is associated with decreased brain functional dynamics flexibility.
- This neuroplasticity indicates significant brain reorganization related to motor skill acquisition and learning.
