The characteristics of participants are described in Characteristics of participants.BMI, body mass index; training; S-HIIT, short high-intensity interval training; L-HIIT, long high-intensity interval training; MICT, moderate intensity continuous; M, Male; F, Female. Data presented as mean ± standard deviation.There were significant difference between groups for changes on Comparison between and within groups for dependent variables.MICT, moderate intensity continuous training; L-HIIT, long high intensity interval training; S-HIIT, short high intensity interval training; HbA1c, glycated hemoglobin; HDL, high-density lipoprotein; LDL, low-density lipoprotein; SBP, systolic blood pressure; DBP, diastolic blood pressure; HR, heart rate; * L-HIIT > MICT.# S-HIIT > MICT.Bold values mean p<0.05.In comparison with pre-training values, there was a significant reduction on HbA1c levels for L-HIIT (mean difference [MD] = -1.8 ± 1.8%, p< 0.01), while no significant change was achieved for S-HIIT (MD = -0.92 ± 2.0%, p = 0.09) and MICT (MD = -0.59 ± 1.7%, p = 0.2). Triglycerides levels significantly reduced after L-HIIT (MD = -23.80 ± 39.6 mg/dL, p = 0.04), with no changes for S-HIIT (MD = -23.19 ± 49.0 mg/dL, p = 0.09) and MICT (MD = 5.36 ± 31.9 mg/dL, p = 0.5). There were no significant changes from pre- to post-training on fasting glycemia, total cholesterol, HDL, and LDL (p > 0.05).There was a significant reduction on resting SBP for L-HIIT group (MD = -12.07 ± 15.3 mmHg, p< 0.01), but not for S-HIIT (MD = -7.33 ± 17.1 mmHg, p = 0.1) and MICT (MD = 4.43 ± 13.1 mmHg, p = 0.2).
