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; which, the larger it is, the greater the capacity of that organism to
produce energy through aerobic metabolism. 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 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.
Conclusion: 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), TAS (p=0.945) and TAD
(p=0.597) post test. In both groups, the results of aerobic capacity were below the “Good” or “Excellent” aerobic capacity.
