The purpose of this study was to examine the relationship of a single day measure of heart rate variability (HRV), and the averaged baseline measures of HRV to heart rate recovery (HRR) following maximal exercise. Thirty females (22.9 +/- 3.2 years, 64.8 +/- 8.4 kg) completed four visits (V1-V4), where a 10-min HRV was recorded. Upon completing the V4 recording, a treadmill graded exercise test (GXT) was performed, followed by a 5-min active cool down. HRV was assessed through time domain measures [natural log of root mean square of successive R-R differences (lnRMSSD) and standard deviation of normal to normal intervals (lnSDNN)] and natural log frequency domain measures [low frequency (lnLF) and high frequency (lnHF)]. Variables collected over V1-V4 were measured as; day of (DO) GXT, 3 day (AV3), and 4 day average (AV4). HRR was calculated as the maximal HR achieved minus the HR at: 30-s (HRR30), 1-min (HRR1), 2-min (HRR2), 3-min (HRR3), 4-min (HRR4) or 5-min (HRR5) of recovery. Pearson\'s Product correlations revealed significant correlations (P = < 0.05) between all HRV(DO) measures to each HRR measure and are presented in ranges: lnSDNN (r = 0.442-0.522), lnRMSSD (r = 0.458-0.514), lnLF (r = 0.368-0.469), lnHF (r = 0.422-0.493). For HRV(AV3,) lnRMSSD(AV3) and HRR1 were positively correlated (r = 0.390, P = 0.033). Last, HRV(AV4) showed positive relationships (P = < 0.05) between lnRMSSD(AV4) and HRR30 (r = 0.365, P = 0.048); and for HRR1 and lnSDNN(AV4) (r = 0.400, P = 0.029), lnRMSSD(AV4) (r = 0.442, P = 0.014), and lnHF(AV4 ()r = 0.368, P = 0.045); and lnRMSSD(AV4) and HRR3 (r = 0.381, P = 0.038). Within the current study HRV(DO) displayed the strongest correlations to HRR therefore, averaged resting HRV measures do not strengthen the prediction of cardiovascular recovery following a GXT in this population.
