TREINAMENTO INTERVALADO DE ALTA INTENSIDADE SOBRE A FUNÇÃO FÍSICA DE UNIVERSITÁRIOS OBESOS

Abstract

ABSTRACT Introduction: Obese students easily accept high-intensity interval training due to its combination of exercise and rest. It is believed that, besides promoting the reduction of body mass index due to its aerobic character, such training can also positively impact the physical function of its practitioners. Objective: Study the effects of high-intensity interval training on body indexes and physical function of obese college students. Methods: Twenty obese college students were selected for four weeks of training. Distributed by equal random selection, the experimental group received four sessions of high-intensity interval training per week. The duration of training from the beginning of the preparatory activity to the end of the stretching activity totaled 1.5h. The control group performed their daily activities without intervention. The relevant physical function indices of the volunteers were evaluated and recorded before and after the intervention. Results: The lean mass index of the students in the experimental group increased from 1463,846 ± 209,888Kcal to 1573,514 ± 194,492Kcal. The vital capacity increased from 2573.94 ml to 3553.98 ml. However, students in the control group showed no relevant changes. Conclusion: High-intensity interval training proved useful in improving college students’ general health levels and helping them recover their normal body indexes.
