Resumen

Propósito: El ejercicio aeróbico afecta el estado redox respiratorio. La influencia de diferentes niveles de humedad relativa (HR) en la formación de especies químicas reactivas respiratorias asociadas con el estado redox alterado por el ejercicio ha sido poco explorada. Nuestro objetivo fue evaluar el efecto de dos condiciones de HR diferentes (40% frente a 90%) sobre la concentración de peróxido de hidrógeno y nitrito en el condensado de aire exhalado ([H2O2] EBC y [NO2−] EBC) y parámetros de espirometría en ciclistas recreativos . Métodos: Dieciséis hombres y mujeres (12/4) (edad media ± DE: 23,5 ± 2,2 años) completaron 60 min de ciclismo a 166,3 ± 26,9 vatios (70% de la carga máxima de la prueba V ˙ O 2-máx., 49,3 ± 7,6 mL · min − 1 · kg − 1) en condiciones aleatorias de 40% -RH y 90% -RH separadas por 7 días. La prueba bidireccional RM-ANOVA se aplicó para comparar [H2O2] EBC, [NO2−] EBC, [NO2−] EBC / [NO2−] Plasma en reposo y 80 min post-ejercicio (80-post); y parámetros de espirometría en reposo, 20 postes y 80 postes. Resultados: La interacción de factores (humedad × tiempo) fue significativa en [H2O2] EBC, [NO2−] EBC, [NO2−] EBC / [NO2−] Plasma (p = 0.005, p = 0.030, p = 0.043, respectivamente ). En condiciones de 40% -RH, los mismos parámetros fueron más altos en 80 post que en reposo (p <0,001, p = 0,001, p = 0,014, respectivamente). Al mismo tiempo, el [H2O2] EBC y el [NO2−] EBC / [NO2−] Plasma fueron más altos en 40% -RH que en 90% -RH (p = 0.010, p <0.001, respectivamente). La interacción fue significativa en FEV1 (p = 0,013) y FEF25-75% (p = 0,023), pero no en FEV1 / FVC (p = 0,362). A los 80 postes, los cambios se mantienen en 90% -RH (p <0,001), disminuyendo en 40% -RH siendo similar al reposo. Conclusión: En ciclistas recreativos, 90% -RH previene el aumento de peróxido de hidrógeno y nitrito en muestras de condensado de aire exhalado observado al 40% -RH y prolonga la broncodilatación hasta 80 post ejercicio de ciclismo.

abstract = "Purpose: The aerobic exercise affects the respiratory redox-state. The influence of different relative humidity (RH) levels on the formation of respiratory reactive chemical species associated with redox-state altered by exercise has been poorly explored. Our aim was to evaluate the effect of two different RH conditions (40% vs. 90%) on the concentration of hydrogen peroxide and nitrite in exhaled breath condensate ([H2O2]EBC and [NO2−]EBC) and spirometry parameters in recreational cyclists. Methods: Sixteen men and women (12/4) (mean age ± SD: 23.5 ± 2.2 years) completed 60-min of cycling at 166.3 ± 26.9 watts (70% of maximum load of V ˙ O 2-max. test, 49.3 ± 7.6 mL·min−1·kg−1) at random 40%-RH and 90%-RH conditions separated by 7 days. The two-way RM-ANOVA test was applied to compare [H2O2]EBC, [NO2−]EBC, [NO2−]EBC/[NO2−]Plasma at rest and 80-min post-exercise (80-post); and spirometry parameters at rest, 20-post and 80-post. Results: The interaction of factors (humidity × time) was significant in [H2O2]EBC, [NO2−]EBC, [NO2−]EBC/[NO2−]Plasma (p = 0.005, p = 0.030, p = 0.043, respectively).
