This 12-week randomized controlled trial evaluated a Tabata-style functional high-intensity interval training (HIIT) program in female university students. The intervention involved eight bouts of 20-second 'all-out' functional exercises with 10-second rest periods. Compared to the control group, the HIIT intervention led to favorable changes in cardiorespiratory fitness, most body composition variables, some cardiometabolic outcomes (including systolic blood pressure, HDL, LDL, total cholesterol, fasting insulin, and HOMA-IR), and daily moderate-to-vigorous physical activity and total physical activity. Most benefits for body composition and cardiometabolic risk factors were observed in overweight/obese participants. Limitations included uncontrolled dietary intake, a short follow-up period, and the specific student population studied.

ABSTRACT

Abstract Introduction: The increasing prevalence of metabolic syndrome and physical inactivity enhances exposure to cardiometabolic risk factors in university students. High-intensity interval training (HIIT) improved cardiometabolic health in clinical adults but the evidence in the university setting is limited. Furthermore, few studies examined the effect of low-volume HIIT on habitual physical activity (PA). Therefore, the primary aim of this study was to evaluate the efficacy of 12-week Tabata-style functional HIIT for improving multiple cardiometabolic health outcomes and habitual PA. We also investigated whether changes in habitual PA over the intervention period had an impact on exercise-induced health outcomes. Methods: 122 female freshmen were randomized into the Tabata group (n = 60) and the control (n = 62). The Tabata training protocol involved 8 × 20 s maximal repeated functional exercises followed by 10 s rest with a frequency of 3 times per week for 12 weeks. Body composition, maximal oxygen uptake (VO 2max ), blood pressure (BP), blood lipids, fasting glucose and insulin, C-reactive protein and PA were objectively measured using standardized methods. Dietary intake was measured using a valid food frequency questionnaire. All variables were measured pre- and post-intervention. Results: Mixed linear modelling results showed that there were large intervention effects on VO 2max ( p < 0.001, d = 2.53, 95% CI: 2.03 to 3.00 for relative VO 2max ; p < 0.001, d = 2.24, 95% CI: 1.76 to 2.68 for absolute VO 2max ), resting heart rate ( p < 0.001, d = −1.82, 95% CI: −2.23 to −1.37), systolic BP ( p < 0.001, d = −1.24, 95% CI: −1.63 to −0.84), moderate-to-vigorous intensity physical activity (MVPA) ( p < 0.001, d = 2.31, 95% CI: 1.83 to 2.77), total PA ( p < 0.001, d = 1.98, 95% CI: 1.53 to 2.41); moderate effects on %BF ( p < 0.001, d = -1.15, 95% CI: −1.53 to −0.75), FM ( p < 0.001, d = −1.08, 95% CI: −1.46 to −0.69), high-density lipoprotein (HDL) ( p < 0.001, d = 1.04, 95% CI: 0.65 to 1.42), total cholesterol ( p = 0.001, d = −0.64, 95% CI: −1.00 to −0.26); small effects on BMI ( p = 0.011, d = −0.48, 95% CI: −0.84 to 0.11), WC ( p = 0.043, d = −0.37, 95% CI: −0.74 to −0.01), low-density lipoprotein ( p = 0.003, d = −0.57, 95% CI: −0.93 to −0.19), HOMA-IR ( p = 0.026, d = −0.42, 95% CI: −0.78 to −0.05) and fasting insulin ( p = 0.035, d = −0.40, 95% CI: −0.76 to −0.03). Regression analysis showed that only the percentage change of HDL was associated with the change of MVPA (b = 0.326, p = 0.015) and TPA (b = 0.480, p = 0.001). Conclusion: From the findings of the study we can conclude that 12-week low-volume Tabata-style functional HIIT was highly effective for university female students to improve cardiorespiratory fitness, body fat, some cardiometabolic health outcomes and habitual PA.
