ABARZUA V., Javiera et al. High intensity interval training in teenagers. Rev. méd. Chile [online]. 2019, vol.147, n.2, pp.221-230. ISSN 0034-9887.

This review analyzes the effects of high intensity interval training (HIIT) on muscle and cardiovascular fitness and body composition in teenagers. A search was carried out in international databases, finding 145 papers and selecting five for analysis. In all the reviewed manuscripts, peak oxygen uptake improved after HIIT. In the three manuscripts that measured muscle strength, it also increased. We conclude that HIIT improves muscle strength and cardiovascular fitness in school age children. A 12 weeks protocol with three 12-minute sessions per week would be ideal.

Keywords : Adolescent; Exercise; High-Intensity Interval Training; Physical Fitness.
