“…In the 4-min Tabata training, four functional movements were performed using participants' own body weight. These movements were selected based on the Tabata training recommendations (Tabata, 2019) and showed a good acceptance in female university students in the polit study (Lu et al, 2022a). Participants were encouraged to repeat the movement as many times as possible during the 20-s workout, then rest for 10 s. The four movements were performed in sequence and then repeated, with a total of 4 min exercise.…”

“…Furthermore, since the individualized exercise prescription was not the primary objective of the present study, the utility of age predicted HR max appeared to be acceptable and reasonable. In our previous study, the HR mean achieved during exercise was 82.4% ± 1.9% of age predicted HR max (Lu et al, 2022a). To reflect the high intensity, a cut-point of 80% of HR max was used to evaluate the intervention fidelity (Garber et al, 2011).…”

“…The compensatory behaviors may explain in part why the intervention did not produce the results expected (King et al, 2008). The short-term effects on compensatory movement behaviors following a Tabata-style HIIT had been investigated in our previous study and the results showed an increase in both sedentary time and moderate-to-vigorous intensity physical activity (MVPA) (Lu et al, 2022a).…”

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 (VO2max), 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 VO2max (p < 0.001, d = 2.53, 95% CI: 2.03 to 3.00 for relative VO2max; p < 0.001, d = 2.24, 95% CI: 1.76 to 2.68 for absolute VO2max), 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.
