Abstract

Propose: The aim of this study was to compare the kinetics of heart rate (HR) recovery (HRrec) in times of analysis on 120 s (T120), 300 s (T300) and 600 s (T600) after a maximal incremental test. Methods: thirteen handball players (23.5±4.1 years; VO2max 47.6±2.2 ml.kg.min-1) performed the 30-15 Intermittent Fitness Test (30-15IFT). The HRrec was analyzed during 10 minutes on seated position after 30-15IFT for the determination of kinetics of HRrec on the times analyzed. The HR was recorded by heart rate monitor (POLAR®, s810i). Results: The T120 resulted a minimum HR in 600 s lower in comparison with T300, T600 and with the true value of HR on 600 s (~10%). A moderate correlation between the T30 and the time constant (HRτ) on T120 and T300 ((= 0.77 and 0.54; P < 0.05), respectively. There was a lower agreement among the HRrec kinetics parameters obtained with T120 compared with T300 and T600. This way, the times analyzed in T300 and T600 are better for kinetics of HRrec, however for operational reasons, we suggest the use of the T300.
