The study showed that overtraining can cause elevated dopamine levels in the hippocampus even during rest. This explains the link between excessive training and conditions such as sleep disturbances and anxiety in athletes.
How too much exercise affects the brain
According to data obtained from work with mouse models from Brazil, excessive physical exertion can alter chemical processes in the brain. The scientists concluded that even after intense training, dopamine levels in the hippocampus remain elevated, which is a key point for understanding the effects of overload.
Key findings of the study
- Excessive exertion can alter chemical processes in the brain
- Elevated dopamine levels in the hippocampus persist even during rest
- Sleep disturbances and anxiety may be linked to overtraining
These findings underscore the importance of adequate recovery for athletes to avoid an imbalance in neurotransmitter function.
