Heart rate recovery is a valuable parameter for assessing autonomic balance, but its methodology and interpretation require standardization across different exercise and recovery protocols.
Standardization of cardiopulmonary exercise test protocols and recovery periods is necessary for accurate determination and interpretation of heart rate recovery as a measure of autonomic balance.
Heart rate recovery warrants cautious clinical interpretation; leaves open its routine use pending protocol standardization.
Determination of the heart rate recovery (HRR) after the session of a physical activity, represents the valuable parameter for the investigation of autonomic balance and its dynamic in the general population, but also in the population of elite athletes. However, the methodology for its determination and analysis is still not entirely specified. It is necessary to define an adequate protocol of cardiopulmonary exercise test, by choosing an adequate ergometer (treadmill, ergo-bicycle or step bench). Organization of recovery period (active or passive), after the session of exercise is also very important, because its protocol interfered significantly with the value of HRR. Interpretation of obtained HRR values varies a lot, and researcher has freedom to choose the most adequate way, in accordance with the objectives of his study. Following paper represents a short review of determination, interpretation and analysis of HRR, followed by the latest recommendations.

Đurić et al. (2016) conducted a review in Autonomic nervous system balance. Heart rate recovery assessment was evaluated. Heart rate recovery is a valuable parameter for assessing autonomic balance, but its methodology and interpretation require standardization across different exercise and recovery protocols.
