Heart Rate

Complexity Index Interpretation


Fatigue Recuperation

Possible Interpretation


Trained Healthy Subject

Only the heart rate exhibits higher complexity compared to the control group. The rest of the acquired surrogate data are within the control group spread with pronounce low complexity of the data.



The fatigue recovery index indicates that trained subjects can recover from daily cycles of high/low activities significantly faster compared to the control group or healthy subjects. The reactivity index indicates superior capability to react to both internal and external demands compared to the control group. The stress index suggests a balance between demands and regulatory capabilities.

There is no need to change current practices to keep the current high level of neurophysiological abilities.

Healthy Subject

Subject's reaction to change of either external or internal demands lacks in terms of time and/or adequate response compared to trained subject.



The indicated fatigue recovery index suggests that a healthy subject requires significantly more time to recuperate from daily activity. Also the reactivity to deal with demands is low compared to the trained subject considered. It is within the spread of the control group. The stress level is considered low.

Increase of the periodic physical activities is recommended.

Control Group



The high level of the mean stress index of the control group seems to be due to exposer to significant clinical requirements impose on the practitioners who formed majority of the control group.
