Key result
Ventilatory threshold identification using VE/VCO2 showed high correlation with individual anaerobic threshold for VO2 (r=0.90), power output (r=0.84), and heart rate (r=0.97; all p<0.01).

May aid noninvasive threshold assessment in cyclists; leaves open prospective validation before clinical adoption.
Cross-Sectional (n=8)
Effect estimate: r = 0.90 (VO2), r = 0.84 (power), r = 0.97 (HR)
p-value: p=<0.01
Ventilatory threshold identification by considering a marked rise on VE/VCO2 reflects the same phenomenon as individual anaerobic threshold in cyclists.
Okano et al. (2003) conducted a cross-sectional in Healthy cyclists (n=8). Individual Anaerobic Threshold (IAT) determination vs. Ventilatory Threshold (VT) determination was evaluated on Correlation between physiological variables (VO2, power output, heart rate) related to IAT and VT (r = 0.90 (VO2), r = 0.84 (power), r = 0.97 (HR), p=<0.01). Ventilatory threshold identification using VE/VCO2 showed high correlation with individual anaerobic threshold for VO2 (r=0.90), power output (r=0.84), and heart rate (r=0.97; all p<0.01).
