Episode notes
Sue Phillips' Tri Journey
- Sue Phillips started triathlon after her kids left home and quickly embraced the sport with strong competitive drive.
- In 10 years, Sue has completed multiple world championships and is close to finishing all seven marathon majors.
Breathing Rate Ties to Perceived Effort
- Breathing frequency closely matches perceived exertion because both are controlled by the same brain region.
- This metric provides a more sensitive measure of effort than heart rate or power alone.
Ventilatory Thresholds from Breathing
- Ventilatory thresholds can be detected through breathing patterns offering individualized training zones.
- Combining breathing rate with tidal volume gives a power meter-like insight into athlete workload and stress.
