Key result
Heart rate and heart rate variability metrics accurately reflected anaerobic threshold during a discontinuous cycle test, with differences between metric threshold and AT of less than 14 W (p≤0.05).

Do heart rate and heart rate variability responses reflect anaerobic threshold in cyclists?
p-value: p=≤0.05
Heart rate and heart rate variability metrics accurately reflect anaerobic threshold during a discontinuous cycle test, providing a potential alternative to ventilatory threshold measurement.
Park et al. (2014) conducted a cross-sectional in Healthy cyclists (n=15). Discontinuous, incremental cycle test vs. Ventilatory threshold (VT) was evaluated on Anaerobic threshold (AT) determined by HR and HRV metrics compared to ventilatory threshold (VT) (p=≤0.05). Heart rate and heart rate variability metrics accurately reflected anaerobic threshold during a discontinuous cycle test, with differences between metric threshold and AT of less than 14 W (p≤0.05).
