ET: Continuous endurance training; HIIT: High-intensity interval training; CO: Control; BMI: Body mass index; BP: Blood pressure; HR: Heart rate; HRMAX: Maximal heart rate.
a Serum glucose was obtained from the metabolomics assay; at posteriori, no subject exhibited a serum glucose > 7 mmol L-1 at baseline. There were no significant differences between groups for any variables (P > 0.01 for all one-way ANOVA tests).
