A non-pharmacological means to treat them is physical exercise, which practiced on a regular basis reduces risk factors. Objective: To determine the effects of high intensity aerobic training and muscle strength in obese staff with CNCD in a Chilean university. Method: A 16-week program was applied in 18 volunteer university staff, who was assigned to a training group (TG) or a control group (CG). This program consisted of interval medium-high intensity exercises in bicycle and localized muscular strength, with duration of 30 minutes per session, three times a week. Pre and post-intragroup (TG and CG) were compared with the T-Student test of related samples and each pre-test and each post-test intergroup with student's Ttest for independent samples (p <0.05) between both groups. Results: In the control group the variables evaluated were maintained and not modified, although increases in triglycerides, systolic and diastolic blood pressure were found, in contrast to the training group, who reported a significant decrease in waist circumference (Pre test: 101.33; Posttest: 97.22) and ICE (Pre test: 0.65; Posttest: 0.62) (p = 0.017), systolic blood pressure, diastolic blood pressure, triglycerides and frequency cardiac arrest, although not significant. In total cholesterol, there were increases, although not significant. On the other hand, the double product (heart rate x systolic blood pressure) was only reduced in the training group. Conclusions: The data suggest that medium-high intensity aerobic interval training improves the hemodynamic response in submaximal exercise in patients with obesity and CNCD. The decrease in abdominal perimeter and ICE is a good indicator of the improvement of body fat.
