Key result
In elite endurance athletes, the 'fatigue' state was associated with a significantly higher supine heart rate (+6.27 bpm) and lower heart rate variability compared to the 'no-fatigue' state.
Why the study?

Does a state of fatigue alter heart rate variability in elite endurance athletes?
Effect estimate: Mean difference +6.27 bpm
Absolute Event Rate: 63.3% vs 55.3%
p-value: p=<0.0001
Fatigue in elite endurance athletes is associated with decreased heart rate variability and increased intra-individual variance, suggesting altered autonomic control.

Fatigue may support HRV monitoring in endurance athletes; leaves open prospective validation before guiding training.
Schmitt et al. (2013) conducted an observational in Fatigue (n=57). Fatigue state vs. No-fatigue state was evaluated on Supine Heart Rate (HR SU) (Mean difference +6.27 bpm, p=<0.0001). In elite endurance athletes, the 'fatigue' state was associated with a significantly higher supine heart rate (+6.27 bpm) and lower heart rate variability compared to the 'no-fatigue' state.
