Key result
Static physical loading caused more marked cerebral blood flow changes and decreased EEG β- and θ-rhythms than dynamic loading, while cyclic loads positively affected cognitive functions.
Why the study?
The study was aimed at evaluating the effects of physical exercise on brain electrical activity, cerebral blood flow, and cognitive function in athletes engaged in cyclic and acyclic sports.
How do dynamic and static physical loads affect brain electrical activity, cerebral hemodynamics, and cognitive function in young male athletes?

How do dynamic and static physical loads affect brain electrical activity, cerebral hemodynamics, and cognitive function in young male athletes?
Cyclic physical loads positively impact cognitive functions in young athletes, whereas static loads cause more marked cerebral hemodynamic changes and decrease specific EEG rhythms.
Static loads may alter cerebral hemodynamics and EEG differently than dynamic ones in athletes; hypothesis-generating, prospective trials needed before practice change.
This work was aimed at studying the effects of physical exercise on brain electrical activity, cerebral blood flow, and cognitive function in athletes engaged in cyclic and acyclic sports. The study was performed on healthy young men at ages of 18 to 23 years. We used cognitive tests, electroencephalography, and rheoencephalography. Cerebral hemodynamics was shown to change after dynamic and static loading. The changes in blood flow after static loading were more marked than after dynamic loading. The results suggest that static loads cause a decrease in the activity of the EEG β- and θ-rhythms in the cognitive testing. It has been shown that cyclic loads have a positive effect on cognitive functions, while no such effects are observed after static loadings.

Капилевич et al. (2019) conducted an observational in Healthy athletes. Dynamic and static physical loading was evaluated on Brain electrical activity, cerebral blood flow, and cognitive function. Static physical loading caused more marked cerebral blood flow changes and decreased EEG β- and θ-rhythms than dynamic loading, while cyclic loads positively affected cognitive functions.
