ABSTRACT

Introduction and objective: The 20 Meter Shuttle Run Test (20mSRT) is a cardiorespiratory fitness test that measures maximal aerobic power and indirectly maximum oxygen consumption (Vo2Máx.); the objective was to compare the aerobic capacity and cardiopulmonary response of university students in Puebla, Mexico against university students in Cúcuta, Colombia.
Materials and methods: Observational, descriptive and cross-sectional study with 2 groups of 100 participants of average age of 20.5 ± 3 and 21 ± 2 years for Mexicans and Colombians respectively. Anthropometry, vital signs, climatic conditions and the 20mSRT test were obtained. In addition, it was analyzed by means of the non-parametric Mann-Whitney test and then ANOVA with post hoc test using the Scheffe test.
Results: 56% (62% Mex and 50.5% Col.) of the participants had a BMI (body mass index) of normal weight, 9.5% (7% Mex and 6% Col.) Underweight and for overweight and obesity was 26% (28% Mex and 24% Col.) and 8.5% (9% Mex. and 8% Col.) Respectively. Regarding abdominal circumference, 93.73±11.84 and 81.37±12.20 were found for Mexican and Colombian university students, respectively. The VO2max. in the Mexican university students it was 34.7±6.06 with 672.8±385.4 meters and in the Colombian universities it was 32.9±7.12 with 533.8±371.3 meters.
Conclusions: No significant differences were found in BMI (p=0.967), abdominal circumference (p=0.258), VO2max. (p=0.089) nor hemodynamic variables such as maximum heart rate (p=0.344), arterial oxygen saturation (p=0.811), systolic blood pressure (p=0.945) and diastolic blood pressure (p=0.597) post test. In both groups, the results of aerobic capacity were below the "Good" or "Excellent" aerobic capacity.
