“…One of the pioneers in the field was Javorka et al [ 12 ], who did not observe a significant correlation between resting parasympathetic activity with relative HRR and parasympathetic reactivation in the 1 st and 5 th minute after submaximal exercise. In the same direction, Molina et al [ 14 , 15 ] published studies that did not observe a correlation between absolute and relative HRR at the 1 st minute with parasympathetic activity in the supine position and the standing position following maximal treadmill exercise testing in healthy men.…”

“…On the other hand, some authors have shown divergent results considering the relationship between resting parasympathetic activity with HRR and parasympathetic activity after the exercise test [8][9][10][11][12][13][14][15][16]. One of the pioneers in the field was Javorka et al [12], who did not observe a significant correlation between resting parasympathetic activity with relative HRR and parasympathetic reactivation in the 1 st and 5 th minute after submaximal exercise.…”

“…On the other hand, most studies on HRR focused on the recovery in the first minute and the third minute after exercise [8][9][10][11][12][13] and there are a few literature reports in which both early and late HRR has been examined [14][15][16]. Additionally, different implications of exercise physiology can be appreciated with a comprehensive analysis of HRR beyond the first minute.…”

“…Even though those physiological measurements mentioned above are considered independent predictors of risk for cardiovascular mortality [1][2][3], some studies have investigated the association between parasympathetic activity at rest, evaluated by heart rate variability (HRV), with HRR [8][9][10][11][12][13][14][15][16] by considering it to be a promising area of clinical and functional evaluation.…”

“…In this clinical setting, some studies have reported a significant association between resting parasympathetic activity with HRR after a maximal or submaximal incremental exercise test [9,11,[14][15][16]. When evaluating the HR during the exercise, only one study showed a significantly positive association between parasympathetic activity at rest with chronotropic reserve (CR); the difference between HR at peak exercise and the RHR in the supine position, during the maximal exercise test [16].…”

Can resting heart rate explain the heart rate and parasympathetic responses during rest, exercise, and recovery?

The effect of resting heart rate (RHR) on the heart rate (HR) dynamics and parasympathetic modulation at rest, exercise, and recovery remain to be clarified. This study compares HR and parasympathetic responses at rest, during submaximal exercise testing and recovery in young, physically active men with different RHR average values. HR and parasympathetic responses were compared between two groups: bradycardia group–RHR < 60 bpm (BG, n = 20) and normocardia group–RHR ≥ 60 ≤ 100 bpm (NG, n = 20). A Polar RS800® was used to record the RR-interval series and HR at rest in the supine position, following the postural change (from supine to orthostatic position) and in the orthostatic position for 5 minutes, as well as during and after a submaximal exercise testing. Statistical analysis employed the MANOVA, Mann-Whitney, and Simple Linear regression test with a two-tailed p-value set at ≤ 0.05. BG at rest showed lower HR in the orthostatic position, higher parasympathetic activity in the supine and orthostatic positions, and higher parasympathetic reactivity than NG (p ≤ 0.01) after the postural change. BG before exercise showed lower HR and higher values of the chronotropic reserve and parasympathetic withdrawal than NG (p ≤ 0.01) throughout the exercise. Following the exercise, BG showed higher values of HR recovery (HRR) and parasympathetic reactivation in the 3rd and 5th minutes of recovery than NG (p ≤ 0.01). Lastly, the RHR can explain the variance of the HR at rest, during exercise testing, and recovery from 11 to 48%. We concluded that BG (RHR < 60 bpm) showed higher chronotropic and parasympathetic modulation at rest, higher chronotropic reserve, parasympathetic withdrawal during the submaximal exercise test, and faster HRR and parasympathetic reactivation after effort in young physically active men.
