Ventilatory Thresholds Assessment from Heart Rate Variability during an Incremental Exhaustive Running Test
Key result
Heart rate variability analysis accurately estimated ventilatory thresholds compared to classical respiratory methods during an incremental running test (R2=0.94 for VT1, R2=0.96 for VT2; p<0.001).

I
Intervention
Heart rate variability (HRV) analysis using smoothed pseudo Wigner-Ville distribution (SPWVD) to assess ventilatory thresholds from respiratory sinus arrhythmia (RSA)
C
Comparator
Classical respiratory measurement devices using the ventilatory equivalent method
O
Outcome

Cottin et al. (2007) conducted an observational in Professional soccer players (n=12). Heart rate variability (HRV) analysis vs. Ventilatory equivalent method (respiratory components) was evaluated on Correlation between ventilatory thresholds assessed by respiratory components (VT1/VT2) and HRV (HFT1/HFT2) (R2 = 0.94 (VT1) and 0.96 (VT2), p=< 0.001). Heart rate variability analysis accurately estimated ventilatory thresholds compared to classical respiratory methods during an incremental running test (R2=0.94 for VT1, R2=0.96 for VT2; p<0.001).
