Notes: Data retrieved from flash glucose monitor. All values are expressed as mean ± standard deviation. A two‐way repeated measures ANOVA was used to determine statistical difference between groups unless otherwise indicated. A McNemar's test (indicated by a) or paired parametric t test (indicated by b) were also used to determine statistical difference between groups. Significant values were bolded where appropriate.
Abbreviations: CI, confidence interval; HIIT, high‐intensity interval training; MICT, moderate‐intensity continuous training; n (%), number of individuals and percentage of total participants.
