Variability of heart rate in sportsmen aimed at power training
Heart rate variability in sportsmen involved in power training with powerlifters at relative rest was studied. The research revealed decline of both temporary and spectral indices of heart rate variability (RMSSD, pNN50, HF) in sportsmen doing the powerlifting in comparison with the control group. The received data make it possible to conclude that hemodynamic support of sportsmen aimed at power training happens at a higher tense of regulation mechanisms of heart activity.
