Valores de referencia para las pruebas de Cooper y de 20m de ida y vuelta en población residente en altitud elevada. [Reference values for Cooper and Shuttle Run Tests in population living at high altitude].

Abstract

The aim of this study was to report the reference values for indirect VO2max obtained in the Cooper Run Test (CRT) and Shuttle Run Test (SRT-20m) in trained young population residing at high altitude, between 2600 and 3700 meters above sea level (masl). A total of 614 physically active subjects (118 women, 496 men; 20.2±2.3 years; 65.3±10.3 kg; 169.1 ± 7.8 cm; 22.7±2.8 kg·m-2) residing in Bogotá, or municipalities of the metropolitan area, participated in this cross-sectional study. The VO2max percentiles were established for the CRT and SRT-20m tests in the study population, highlighting that the records obtained in the SRT-20m were higher than CRT. VO2max values in subjects living at <3000 masl were lower compared to those living at 3001 – 4000 masl (p=0.01); likewise, women showed a lower level of cardiorespiratory fitness (CRF) than men (p<0.01). In conclusion, these reported values can be used for the evaluation of the CRF of populations with similar characteristics. On the other hand, the variations found in VO2max values might be associated to genetic variants (e. g. polymorphisms) or to training adaptations (e. g., training specificity, running technique); however, more research is required on these aspects in this type of population.
