Introduction: There is a high prevalence sedentary, overweight and obesity in young college. Objective: The purpose of this study was to determine the effects of a program of high intensity interval training program (HIIT) on the anthropometric profile, basal blood glucose and VO₂ max of young sedentary with malnutrition by excess. Material and methods: 6 women and 2 men (2 obese and 6 with overweight) were submitted to a training program for high intensity of 8 weeks duration (3 session/week). It was evaluated in fasting and later to 72 hours after the last intervention; weight, body mass index (BMI), contour waist (CW), perimeter hip and basal blood glucose. The VO₂ max was assessed in normal conditions prior to the first meeting. Results: The study variables did not present significant changes (p > 0.05), but they brought percentage decreases. The weight decreased by 0.18%, the BMI 0.27%, the CW 2.67%, the perimeter hip a 1.15%, and the VO₂ max 0.48%. The basal blood glucose presented the biggest decrease, from 95.13 ± 23.91 to 89.88 ± 12.45 mg/dl (5.52%), stabilizing and improving its levels in each of the participants. Conclusions: It was possible to use high intensity interval training program without adverse results for the health of the participants. The basal blood glucose showed the greatest variation, stabilizing their values in the participants, which is a positive indicator within the program. It is necessary to keep on investigating on this methodology HIIT and to increase the learning times to see the changes that can take place in different parameters metabolites, anthropometric, physical in population with malnutrition by excess.
