Why the study?
HRV in the supine position maximizes parasympathetic tone for aerobic sports, but team sports rely on anaerobic intermittent bouts with sympathetic activation and vagal withdrawal. It was hypothesized that HRV during sympathetic activation and vagal withdrawal would be useful to evaluate perceived physical fitness in team sports.
Does Heart Rate Variability (HRV) correlate with perceived physical fitness in professional soccer players?
Does Heart Rate Variability (HRV) correlate with perceived physical fitness in professional soccer players?
Standing spectral HRV analyses may be a useful method for evaluating perceived physical fitness in team sports, and RMSSD may reflect overall HR variability rather than just parasympathetic influence.
No takes yet. Share an insight, caveat, or question.
HRV indices may associate with perceived fitness in soccer players; leaves open validation of spectral measures in larger cohorts.
