Abstract
This study introduces a new methodology for the assessment of intercerebral sources of brain activity during prolonged physical activity. The approach combines interpreting electric brain activity with help of the sLORETA programme with methods of stress physiology.
It shows the possibilities of depicting brain activity, including deep brain structures, with simultaneous monitoring of current metabolic levels. This allows for the assessment of the underlying brain activity during both aerobic and anaerobic metabolism and even a very sensitive adjustment of the amount of required physical activity, accordingly.
This method can be used in both sports and rehabilitation medicine and helps to deepen our understanding of the impact of physical activity on brain activity with a series of neurological and internal conditions. The study is divided into three parts.
The first explains the methodology of electroencephalographic signal processing with help of the sLORETA programme, including statistical processing and its 3D display. The second looks at the relationship between brain activity and physical movement.
The third part discusses an experiment and introduces studies on changes in brain activity during simple, repetitive movements inspired by Chinese health exercise, and during a controlled stress test on a bicycle ergometer in a group of endurance athletes, soldiers and non-athletes.
