Key result
Heart rate threshold matches ventilatory threshold power output during incremental cycling protocols.
Why the study?
An objective method for identifying the heart-rate threshold in cyclists was needed to improve accuracy in training level determination.

May support field-based threshold assessment in athletes; leaves open prospective validation against clinical outcomes.
Wyatt et al. (2005) conducted a cross-sectional in Healthy experienced cyclists (n=15). Discontinuous incremental cycle test vs. Ventilatory threshold (VeT2W) was evaluated on Difference in power output between heart rate threshold (HRTW) and ventilatory threshold (VeT2W) (2.0 W difference, p=>0.05). Heart rate thresholds determined via a discontinuous incremental cycling protocol showed no significant difference in power output compared to ventilatory threshold (2.0 W mean difference), providing a valid field measure for anaerobic threshold.
