  1. Continuous variables are presented as mean ± SD, whereas dichotomous or categorical variables are presented as %, RT-HIIT resistance training and high-intensity interval exercise group, AT-HIIT moderate-intensity and high-intensity interval training group, UC usual care, BMI body mass index, MVPA objectively measured moderate- to vigorous-intensity physical activity, SED objectively measured sedentary behaviour, SD standard deviation.
