Abstract

The purpose of this study was to obtain evidence of validity and reproducibility of the heart rate variability (HRV) response during running. Nineteen men performed two maximum progressive tests (test and retest with intervals of 3 to 7 days) with an initial speed of 5 km.h-1 and increments of 1 km.h-1 every 3 minutes (1% constant slope) until exhaustion. Gas exchange, blood lactate and heart rate variability data were obtained throughout the tests. Results showed that analysis of the HRV provided good estimates of aerobic and anaerobic thresholds identified by lactate and ventilation responses. Additionally, HRV thresholds provided reproducible thresholds. Results confirmed that aerobic and anaerobic thresholds may be identified by HRV data set.
