Episode notes
Fatigue as a Symptom
- Fatigue is best understood as a symptom, similar to pain, measurable only through self-reporting.
- This contrasts with traditional physiological measures, requiring a broader perspective on fatigue.
Two Domains of Fatigue
- Fatigue can be categorized into performance fatigue ability and perceived fatigue ability.
- Performance fatigue is about decrements in muscle activation or force, while perceived fatigue relates to the runner's overall feeling and the ability to handle it.
Perceived Fatigue in Ultramarathons
- Ultramarathon runners experience perceived fatigue fluctuations during races.
- These fluctuations highlight the mental aspect of ultramarathons, where perceived fatigue can change even without physical rest.
