Key result
The point of deflection from linearity of heart rate strongly correlated (r=0.94, p<0.01) with the ventilatory threshold in Indian boys, indicating it may be an accurate predictor of the anaerobic threshold.
Why the study?
Can the point of deflection from linearity of heart rate (HRD) be used as an alternative method to determine the ventilatory threshold (VT) in Indian boys?

The point of deflection from linearity of heart rate (HRD) is highly correlated with the ventilatory threshold (VT) and may serve as an alternative method to determine the anaerobic threshold in boys.
Debray et al. (2007) conducted a cross-sectional in Healthy boys (n=26). Heart rate deflection (HRD) vs. Ventilatory threshold (VT) was evaluated on Correlation between VO2 measured at VT and VO2 measured at HRD (r = 0.94, p=<0.01). The point of deflection from linearity of heart rate strongly correlated (r=0.94, p<0.01) with the ventilatory threshold in Indian boys, indicating it may be an accurate predictor of the anaerobic threshold.
