Fig. 1
Shared genetic correlations and heritability estimates of the HR profile during exercise. Genetic correlations (shared heritability), are shown above the diagonal, phenotypically observed correlations are below the diagonal. Heritability estimates (and standard errors) of each trait are between brackets at the y-axis. All of the estimates shown here were highly significant (p < 10−8). Correlations are based on the residual variance after adjustments for age, sex and BMI, exercise-specific variables and genetic-specific variables (only for the genetic correlations)
