Why the study?
Does training load and altitude affect heart rate variability fatigue patterns in elite Nordic skiers?
Does training load and altitude affect heart rate variability fatigue patterns in elite Nordic skiers?
Altitude training periods appear critical as they are likely to increase overreaching risks in elite Nordic skiers, while training load/intensity alone does not show a causal relationship with HRV fatigue patterns.
No takes yet. Share an insight, caveat, or question.
HRV fatigue patterns in elite skiers appear independent of training load; leaves open whether routine HRV monitoring aids fatigue management.
Schmitt et al. (2018) studied this question.
