Abbreviations: BMI, body mass index; HRR30, heart rate recovery at 30 s; HRR1, heart rate recovery at 1 min; HRR2, heart rate recovery at 2 min; HRR3, heart rate recovery at 3 min; HRRh3, heart rate recovery between 30 s and 3 min; PLG, post-load glucose; SBP, systolic blood pressure; TC, total cholesterol; tc_0–3, time constant of heart rate recovery over 0–3 min post exercise; tc_h3, time constant of heart rate recovery estimated from heart rate at 30 s and 3 min. Data are Pearson's correlation coefficients, values in bold indicate P < 0.001, except ^aP < 0.01. All P values were calculated using a Bonferroni correction for multiple testing.
