Comparative StudyCardiac autonomic profile in different sports disciplines during all-day activity.
Physical training and sport activity have a beneficial effect on cardiac autonomic activity. However, the exact impact of different types of sports disciplines on cardiac autonomic function is still unclear. The aim of this study was to evaluate the cardiac autonomic profile in different sports discplines and to determine their impact on cardiac autonomic function by using heart rate variability (HRV), a noninvasive electrocardiographic (ECG) analysis of the sympatho-vagal balance. ⋯ Both endurance and team playing athletic activity induce during all-day a high parasympathetic tone (higher RMSSD, pNN50 and HF, and lower LF/HF ratio). However, only endurance athletic activity has a particularly high global HRV (higher SDNN), indicating thereby that this type sports discipline may have a more substantially favorable effect on the cardiac autonomic profile.
