Objective: Determine the effects of the high intensity game on anthropometric parameters and the physical condition in a sample of rural schoolchildren in Araucanía, Chile.

Material and method: Quasi-experimental study without a control group, in female students and adolescent men (n = 20), with 5 weeks of exercise, 3 times a week, 30 minutes of high-intensity games with an interválic exercise character. Strength tests (abdominal, flex-ext arm, long jump), aerobic capacity (VO2max), and anthropometry (weight, BMI, WC, CC, ICC) in pre and post test were evaluated.

Results: The post test established that the results of the anthropometry tests were not significant. Weight (0.356); BMI (0.790); C. Waist (0.151); C. Hip (0.058); ICC (1.000), unlike the strength and aerobic capacity physical condition tests where longitudinal jump force (0.000); Abdominal strength (0.014); VO2max (0.000), resting FC (0.000); Flexo-ext. Arms (0.004); analyzed with significance value (P <0.05).

Conclusion: 5 weeks of high intensity games improve predictors of cardiometabolic risk such as aerobic capacity and muscle strength in adolescents, benefiting their health and physical condition
