TORTOSA-MARTINEZ, Miguel; GIL-MADRONA, Pedro; PASTOR-VICEDO, Juan Carlos  and  CONTRERAS-JORDAN, Onofre. Effects of an After-School Physical Activity Program on Overweight Adolescents. Rev.latinoam.cienc.soc.niñez juv [online]. 2016, vol.14, n.1, pp.577-589. ISSN 1692-715X.  https://doi.org/10.11600/1692715x.14139190315.

The aim of this study was to test the effectiveness of an extracurricular sport and physical activity program (PAP) with a group of overweight-obese adolescents for a period of six months, comparing differences in maximum oxygen uptake, recovery heart rate, blood pressure and waist / hip body fat index, as well as differences in the results based on gender. The study was conducted with 38 junior high school students with a BMI above the 85th percentile. Results showed significant improvements in the experimental group (EG) after completion of the PAP compared to the control group (CG). Improvements were observed in the EG in physiological and anthropometric variables and also based on gender. Moreover, the data obtained from the CG reflects a slight improvement in the VO2max but not in the other variables. These results suggest the importance of an adequate program of physical and sporting activities to contribute to improving cardiovascular parameters in adolescents.
