Note: data are presented for all participants (all) and separated by randomisation group (waitlist control (WLC); high intensity interval training (HIIT); yoga (yoga); combination (HIIT+yoga)). All group comparisons between continuous variables were complete using one-way analyses of variance; the comparisons between categorical variables were done using χ2 tests.
