BACKGROUND: Performance of high-intensity interval training (HIIT) by children and adolescents improves physical and health-related fitness, as well as cardiometabolic risk factors. OBJECTIVES: To assess the impact of HIIT performed at school, ie, both in connection with physical education (intra-PE) and extracurricular sports activities (extra-PE), on the physical fitness and health of children and adolescents. METHODS: PubMed and SPORTDiscus were searched systematically utilizing the following criteria for inclusion: (1) healthy children and adolescents (5 to 18 years old) of normal weight; (2) HIIT performed intra- and/or extra-PE for at least 5 days at an intensity >= 80% of maximal heart rate (HRmax) or peak oxygen uptake (VO2peak) or as Functional HIIT; (3) comparison with a control (HIIT versus alternative interventions); and (4) pre- and post-analysis of parameters related to physical fitness and health. The outcomes with HIIT and the control interventions were compared utilizing Hedges' g effect size (ES) and associated 95% confidence intervals. RESULTS: Eleven studies involving 707 participants who performed intra-PE and 388 participants extra-PE HIIT were included. In comparison with the control interventions, intra-PE HIIT improved mean ES for neuromuscular and anaerobic performance (ES jump performance: 5.89 +/- 5.67 (range 1.88 to 9.90); ES number of push-ups: 6.22 (range n/a); ES number of sit-ups: 2.66 +/- 2.02 (range 1.24 to 4.09)), as well as ES fasting glucose levels (-2.68 (range n/a)) more effectively, with large effect sizes. Extra-PE HIIT improved mean ES for neuromuscular and anaerobic performance (ES jump performance: 1.81 (range n/a); ES number of sit-ups: 2.60 (range n/a)) to an even greater extent, again with large effect sizes. Neither form of HIIT was more beneficial for parameters related to cardiorespiratory fitness than the control interventions. CONCLUSION: Compared to other forms of exercise (eg, low-to-moderate-intensity running or walking), both intra- and extra-PE HIIT result in greater improvements in neuromuscular and anaerobic performance, as well as in fasting levels of glucose in school children.
