RESUMEN
Introducción y objetivosEn la corta historia de la ergometría moderna (50 años aprox.) se han producido notables cambios en la atmósfera que respiramos a nivel de grandes, medianas y pequeñas partículas; también a nivel de la composición gaseosa, con aumentos del gas carbónico (CO2) en torno al 125%. Esta situación se agrava dentro de los edificios, que es donde se ubican los laboratorios de fisiología del esfuerzo.El objeto del presente estudio fue comprobar cómo afectan estos cambios atmosféricos a los humanos durante el esfuerzo.MétodosSe realizó estudio comparativo mediante dos pruebas cicloergométricas, apareadas, en 13 sujetos (12♂+1♀). Una se hizo en la situación habitual del laboratorio (indoor) y la réplica se hizo en el mismo laboratorio, dentro de una burbuja con un sitema de filtrado de grandes, medianas y pequeñas partículas, tomando el aire del exterior del laboratorio, (aire libre, outdoor). Los parámetros que se controlaron fueron la potencia máxima conseguida en el cicloergómetro y expresada en vatios (W), los parámetros ergoespirométricos (VO2max, VCO2max, VEmax), los parámetros cardiológicos ritmo cardíaco por minuto y los niveles de ácido 2-hidroxipropanoico (La++) y la glicemia en sangre capilar arterializada.ResultadosNo se modificaron estadísticamente los parámetros ergoespirométricos, cardíacos, así como los relativos a la potencia alcanzada en el cicloergómetro, cuando comparamos las dos situaciones estudiadas. Sin embargo, los sujetos mostraron un mayor nivel de lactato arterial capilarizado (+117%) a los 3minutos de finalizar la prueba en situación indoor (7,55±1,81 vs 6,44±1,76mMol/dl; p<0,016; n=13).Idéntico comportamiento observamos en los niveles de glucosa en sangre capilar, que mostraron un incremento del 112% en la situación habitual (indoor) en comparación con los de la burbuja de aire purificado y exterior (glicemia 90,0±12,2mg/dl vs 82,15±6,94mg/dl; p>0,054 no significativo; n=13)(AU)
ABSTRACT
Introduction and objectivesIn the short history of ergonomics (approximately 50 years) there have been notable changes in the atmosphere that we breathe, such as large, medium and small particles, as well as the gas composition, with increases in carbon dioxide (CO2) of about 125%. This situation becomes worse within the buildings where the physiology exercise laboratories are located.The objective of this study was to determine how these atmospheric changes affect humans during exercise.MethodsA comparative study was conducted by means of 2 paired ergometric bicycle tests on 13 subjects (12 males and 1 female). One was carried out in the normal laboratory situation (indoor), and the repeat was done in the same laboratory, with a bubble with a system that filtered large, medium and small particles, breathing the air outside the laboratory (outdoor). The parameters that were controlled were the maximum power achieved on the ergometric bicycle expressed in watts (W), the ergospirometer parameters (VO2max, VCO2max, VEmax), cardiological parameters heart beats per minute and 2-hydroxypropanoic acid (La++) levels and arterialised capillary blood glucose.ResultsThe ergospirometer and cardiac parameters, or those associated with the power achieved on the ergometric bicycle did not change statistically, when we compared the two situations studied. However, the subjects did have higher levels of arterialised capillary lactate (+117%) 3min after finishing the indoor situation test (7.55±1.81 vs 6.44±1.76mMol/dl, P<0.016; n=13).We observed identical behaviour in the capillary blood glucose levels, which showed an increase of 112% in the usual situation (indoor) compared to those in the purified (outdoor) air bubble (blood glucose 90.0±12.2mg/dl vs 82.15±6.94mg/dl; P>0.054 (not significant, n=13)(AU)
