“…For example, Falgairrete et al 8 , carried out measurements between 300 to 3700 masl, affirming that SRT-20m underestimated VO 2 max obtained in the laboratory, but is more stable to predict physical condition in different ages. In the study proposed by Duperly et al 7 , where 64 young adults residing in the city of Bogota, Colombia, were evaluated, it was concluded that cardiorespiratory fitness can be estimated by the VO 2 max obtained in direct and indirect tests; however, within the field tests with greater validity, they point to the SRT-20m as the most suitable for determining VO 2 max in population living at high altitude, this being similar to what was reported by Ramírez et al 15 , who evaluated this same test in schoolchildren, finding closeness among the values reported by the SRT-20m compared to laboratory test data; however, these authors indicate the importance of applying a correction factor; in order to adjust aspects that at high altitudes become analysis variables such as: temperature, humidity, barometric pressure and physiological adaptations of subjects.…”

“…Physiological adaptations at moderate altitudes can potentially alter VO 2 max estimation when either field or laboratory tests are applied. Aspects such as the perception of maximum effort, central peripheral fatigue, and cognitive performance can lead to changes in pH, hemoglobin mass, and pulmonary hemodynamics 7 .…”

“…The frequency will be mediated by audio, which modulates the initial rate, starting at 8.5 km/h, increasing 0.5 km/h for each minute. The VO 2 max estimate proposes various validated equations from Leger's study using as a formula (5 857 x Speed (km/h-19 458), taken up in several studies by Duperly et al 7 , and García et al 6 , which report that this test has been applied in other disciplines demonstrating its validity, which is associated with changes in rhythm that favor the motivation and concentration of the participant.…”

Introducción: Diversas investigaciones han empleado las pruebas de campo con la finalidad de establecer el fitness cardiorrespiratorio a partir del VO2máx obtenido; no obstante, en condiciones de gran altitud pueden existir variaciones que influencien el comportamiento de esta variable en sujetos sanos entrenados y no entrenados. Objetivo: El objetivo de este estudio fue comparar el VO2max obtenido mediante dos pruebas de campo: Cooper Run Test y Shuttle Run Test 20 metros (CRT y SRT-20m) y los valores obtenidos mediante ergoespirometría. Método: Estudio descriptivo de corte transversal; participaron 30 sujetos entrenados (8 mujeres 22 hombres), con una edad promedio de 19,0 ± 2,2 años para las mujeres y 20,1 ± 2,1 años para los hombres. Se aplicó un análisis de varianza de una vía; posteriormente se realizó un análisis post hoc con el procedimiento de Games-Howell, que es más poderoso en muestras pequeñas (p<0.01). Resultados: No se encontraron diferencias significativas en la media del VO2max para SRT-20m y el método directo, sin embargo, con respecto al CRT, se presentaron diferencias (p <0.01), reflejando la mayor precisión de la rueba SRT-20m para estimar el VO2max. en la muestra evaluada. Conclusiones: Nuestros resultados sugirieron que SRT-20m predijo los valores de VO2máx de manera cercana a los datos reportados en ergoespirometría tanto en hombres como en mujeres que habitan a gran altitud. Se justifica la investigación adicional con tamaños de muestra más grandes.

Objective To evaluate the impact of a curricular intervention to promote health-related fitness (HRF) among medical students in Bogota, Colombia. Method The study was conducted between May 2014 and December 2015 as part of the medical physiology course, in which 208 medical students were enrolled.The curricular intervention included two lectures on physical activity (PA) and student-led group presentations on the physiological effects of exercise on human physiology. An academic incentive (10% of final grade) was given to students who reported and documented regular PA practice during the semester. This study assessed students’ HRF variables, perceptions of the curriculum intervention, and PA practices using quantitative and qualitative approaches. Results 55% of the students were female, with a mean age of 19.5 years. Body fat, estimated maximum oxygen consumption (VO2max), handgrip, and sit-up strength showed statistically significant improvements at the end of the intervention. Students reported that PA practice was positively influenced by the curriculum intervention, particularly the academic incentive and the HRF tests. Students reported a wide variety of PA practices, which were mainly done with friends, classmates, or family members. Lack of time was the main reported barrier to PA practice. Conclusion The curricular intervention was effective in improving HRF and promoting PA. It remains to be investigated whether these gains are sustained over time.
