Abbreviations: 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; SD, standard deviation; tc0–3, time constant of heart rate recovery over 0–3 min post exercise; tch3, time constant of heart rate recovery estimated from heart rate at 30 s and 3 min; VO2max(M), estimated maximal oxygen consumption using Milligan equation; VO2max(S), estimated maximal oxygen consumption using Sharkey equation; VO2max(AVD), estimated maximal oxygen consumption using Astrand/Van Dobeln equations. Missing variables account for the different N's. Post-load glucose values were restricted to those receiving 100 g glucose.
