Altered relationship between R-R interval and R-R interval variability in endurance athletes with overtraining syndrome

Autonomic dysfunction decreases within‐subject correlation between R‐R interval length (RRi) and vagally mediated RRi variability in cardiac disease. We tested the hypothesis that overtraining syndrome (OTS) may also weaken this relationship. Nine OTS and 10 control endurance athletes underwent 24‐h...
