This pattern of exercise may be repeated several times. Because of this, they started looking for methods that were efficient, didn't cost a lot of money, and could burn a lot of calories in a short period of time to establish a home-based weight reduction programme that is successful via the use of HIIT. The primary purpose of this research is to investigate the effects of HIIT on a participant's physical fitness components. 60 schools were chosen, and individuals were selected for this study and being randomly allocated to either the experimental group (n = 30) or the control group (n = 30). The High Intensity Interval Training (HIIT) programme was implemented 30 seconds of each exercise followed by 10 seconds of recovery. This routine was repeated by all of the individuals for a total of 12 weeks. The number of exercise repetition was also increased in staircase method. The pre- and post-treatment mean values showed a significant result in experimental the groups (<0.05) and control group did not show any improvement. This study provides the evidence that HIIT is proved effective in improvement of health-related physical fitness components among school going children Keywords: HIIT training, school children, health related components Introduction When it comes to the treatment of childhood obesity, physical activity is absolutely essential. Historically, moderate-intensity continuous training (MICT) has been the most popular type of exercise that has been recommended to enhance both cardiorespiratory fitness (CRF) and body composition. When it comes to altering body composition or other health indices in obese children and adolescents, High Intensity Interval Training (HIIT) has been shown to be more time efficient than moderate intensity continuous training (MICT) in recent years, according to expanding evidence gathered in controlled laboratory settings (Sharma et al., 2022) [6] . It is critical for parents to ensure that their children have a positive experience both during and after high-intensity interval training (HIIT). In children who are overweight, a lower intensity of physical activity was found to have a negative association with exercise adherence, according to a previous study. However, Malik and his colleagues stated that affect reactions during HIIT are based on the intensity of the work-interval and are not wholly negative (unpleasant feelings). They said this in their study. The HIIT protocol with a greater intensity (85% peak power) produces the same amount of enjoyment as the HIIT protocol with a lower intensity (70% peak power), but only the HIIT protocol with 85% peak power generates enough HR stimulation to facilitate potential health benefits. Schools are the perfect places to carry out programmes that encourage students to engage in physical activity (Meng et al., 2022) [5] . The purpose of the study was to investigate the effect of 12 weeks of HIIT effect of health-related physical fitness components. Methodology He study was conducted in Kendriya Vidyalaya No.1, Gwalior (Madhya Pradesh), India. Both parents and their children provided informed consent. The research data was collected in the school playground.
