Objective: The aim of this study was to evaluate the effect of HIIT and SIT programmes on body composition, blood pressure, lipid profile, glucose, cardiorespiratory fitness, and strength of adolescents and to compare the effect between those different protocols.The aim of this study was to evaluate the effect of sprint interval training and high intensity interval training on metabolic and blood biomarker, body composition and physical fitness of adolescents.Methods: Sixty adolescents were recruited from a high school and were randomly placed into three groups. SIT and HIIT undertook a training for 8 weeks, twice a week, for 12 minutes per session, during their Physical Education lessons. SIT group performed 6 sets of 60 seconds of work (90-95%HRmax) / 60 seconds of rest (50-55%HRmax), and HIIT group performed 3 sets of 2 minutes of work (80-85%HRmax) / 2 minutes of rest (50-55%HRmax). Results: After adjustment by sex, both experimental groups exhibited a significant reduction in fat mass (p<0.01), and trunk fat mass (p<0.01), as well as a significant increase in lean mass (p=0.01; <0.01), hand-grip strength (p<0.01) and standing long jump (p=0.05-0.04, respectively). In addition, HIIT showed a significant (p<0.05) improvement in blood pressure, diastolic blood pressure, heart rate and VO2max, and a tendency towards a significant reduction in low density lipoprotein.The implementation of a HIIT protocol within high school Physical Education sessions, maintained for 8 weeks, at a rate of 3 sets of 2 minutes of work (80-85% RHR)/2 minutes of rest (50-55% RHR) generated adaptations such as improved fitness condition, changes in body composition, and improvements in blood parameters and blood pressure. However, the group of adolescents who performed SIT, shorter but more intense sets, did not experience as many benefits. 1 Con formato: Justificado Con formato: Inglés (Estados Unidos) Con formato: Inglés (Estados Unidos) Con formato: Inglés (Estados Unidos) Con formato: Inglés (Estados Unidos) Con formato: Inglés (Estados Unidos) Con formato: Inglés (Estados Unidos
