High-intensity interval training is used to improve maximum oxygen intake and aerobic functional capacity of school children. So far, it has been discovered that high-intensity interval training (HIIT) is effective in improving anaerobic capacity. Aim of the study was to determine the effectiveness and impact of HIIT training on the improvement of VO2 in schoolchildren based on a systematic review of a large number of studies that have addressed the impact of high-intensity interval training. Following
electronic databases were searched: Google Scholar, PubMed, Web of Science and Research Gate, using all papers available by April 30, 2020. The following keywords were used: "high-intensity interval", "training", "HIIT", "training". The search was mostly
related to English and original scientific papers from available journals. In the first phase of the search, the relevance of the titles and abstracts of the identified papers was checked. In the second phase of the search, the complete papers were downloaded and considered for inclusion. References from all collected papers were reviewed to obtain more research that studied this area. Total of 10 studies met the criteria and were included into the systematic review. High-intensity interval training leads to the
improvement of VO2, VO2max, O2 and other physiological parameters in school children by applying various high-intensity interval training programs. Programs in duration of six, ten and twelve weeks lead to the improvement of physiological parameters of school children, while the seven-week program of high-interval training proved to be the best program in relation to the duration and intensity of the program. Based on the analysis and discussion of the papers observed in the systematic research, it can be concluded that, according to the duration of the program, the minimum period where VO2 and VO2max and other physiological abilities can improve is six weeks, and the usual weekly load is two to three workouts per week.
