HFnu may aid taper monitoring in elite swimmers; hypothesis-generating for HRV-guided training, pending prospective trials.
Do heart rate variability changes correlate with training variations and performance in elite swimmers?
In elite swimmers, parasympathetic activity indices (HFnu) after a taper period correlate positively with swimming performance and inversely with fatigue.
Atlaoui et al. (2007) studied this question.
