The role of heart rate (HR) variability as a measure for assessment of autonomic control is presented. Time and frequency domain HR analysis methods are ascribed. H frequency and HR variability patterns that are dependent on baseline level of autonomic control, HR and HR variability responses to active orthostatic test (AOT), physical, and mental loads and the subject’s functional status in trained and non-trained subjects are presented. H variability analysis for evaluation of training process as well as for restoration of cardiovascular system during sleep is proposed. HR frequency and HR variability responses are not uniform for all subjects. The level of HR and HR variability responses and the direction of HR variability changes (a decrease or an increase) are dependent on their baseline level, related to the subject’s functional status. HR frequency and HR variability might be used for evaluation of quality of operators’ mental or physical work loads as well as for control of training process.
