“…Initially, we collected clinical basic physiological data, anthropometrical measurements, and information on lifestyle habits. Afterward, in a quiet exercise physiology laboratory room, at a temperature between 22 to 24°C and relative humidity of 50–60%, continuous HR was recorded according to a standardized protocol previously described to obtain the R-R interval series [ 15 , 17 ]. First, a valid five-minute R-R interval series and HR were obtained following 10 minutes of rest in the supine position.…”

“…The submaximal treadmill exercise test was applied immediately after recording the R-R interval series (at supine and orthostatic postures). Soon after the interruption of the exercise test, the participants proceeded to the post-exercise active orthostatic recovery at 2.4 km/h and 2.5% grade [ 17 ].…”

“…The HR and R-R intervals series were recorded using a valid and reliable heart rate monitor Polar ® (model, RS800CX, Polar ™, Kempele, Finland) with a sample rate of 1000Hz [ 16 , 17 ]. Then, each R-R interval series file was transferred to a computer for offline data processing and analysis of HR and HRV of the R-R interval utilizing the Polar Pro Trainer 5 software and the Kubios HRV software (version 2.2, Kuopio, Finland), respectively [ 19 ].…”

“…After achieving this submaximal intensity (85% of their predicted maximum HR), the exercise test was interrupted, and a 5-minute active recovery period was initiated with volunteers in standing positions at 2.4 km/h and 2.5% grade, as previously described [ 17 , 28 ].…”

“…Indeed, due to different approaches used in those studies above to evaluate resting status, inconsistent results may be produced because the chronotropic response and parasympathetic modulation are adaptative phenomena that are affected by body positions (supine, sitting, or standing), types of exercise test protocols (maximal or submaximal), and types of recovery protocols (active or passive) [ 5 , 17 ].…”

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.
