Abstract:

BACKGROUND: High-intensity interval training intervention in obesity children is gradually increasing, but there remains inconformity within the literature regarding the most effective means for delivering a high-intensity interval training intervention. Childhood obesity is becoming a global health issues, and the identification of effective intervention strategies is imperative.
OBJECTIVE: To perform a meta-analysis to compare the improvement effects between high-intensity interval training and moderate-intensity continuous training on body composition and cardiovascular health in obesity children, and to explore the optimal high-intensity interval training protocol.
METHODS: Five databases (MEDLINE, PubMed, Web of Science, CNKI and Google Scholar) were searched for original research articles. A search of the literature was conducted using the key words about obesity and health. The effects of two training methods on body composition and cardiovascular health were compared.
RESULTS AND CONCLUSION: A total of 295 subjects from 11 studies were identified. The pooled effect size on systolic blood pressure was -0.60 (95% CI: -1.02, -0.18, P=0.01) comparing high-intensity interval training to moderate-intensity continuous training. There was no significant difference between high-intensity interval training and moderate-intensity continuous training on other biomarkers. Elements of reference intervention include: running high-intensity interval training with 0.33 work rest ratio, work intensity ≥ 100% maximal aerobic speed, activity recovery (50% maximal aerobic speed), 6 bouts per session and two or three times weekly and more than 12 weeks. Compared with endurance training, high-intensity interval training has similar improvements on body composition and cardiovascular health of obesity children, and has more time-efficiency. It is possible to carry out exercise interventions for obesity students in the future. Further recommendations as to optimal exercise protocol are needed to improve the intervention effects.
