Background: The breathing mechanism has existed since our birth and accompanies us throughout life. Breathing is an important function in the regulatory process of numerous body functions, its optimization can bring many health benefits. However, many children are unaware of the mechanisms of breathing, namely abdominal or diaphragmatic breathing, and in addition to this, many breathe normally through their mouths. Methods: The present study aimed to verify the influence of a short-term breathing exercise program in school-age girls breathing capacity. Fourteen female students aged between 8 and 10 years were selected, from this selection two groups were formed, the control group (CG) with 7 children and the experimental group (EG) with 7. Through a spirometric test, an assessment of breathing capacity (ABC) was carried out for both groups. The GE participated in a program of breathing exercises (BEP) lasting 15 to 20 minutes for 5 weeks. Then, the ABC was performed again for both groups. Discussion: The results demonstrate a significant increase in the values (p <0.01) of the forced vital capacity (FVC) of the EG, thus suggesting that the application of a BEP promotes the breathing capacity of school-aged girls. Further studies should be performed with larger samples and with a longer protocol.
Resumen. El mecanismo respiratorio existe desde nuestro nacimiento y nos acompaña durante toda la vida. La respiración es una función importante en el proceso regulador de numerosas funciones corporales, su optimización puede traer muchos beneficios para la salud. Sin embargo, muchos niños desconocen los mecanismos de la respiración, a saber, la respiración abdominal o diafragmática, y además de esto, muchos respiran normalmente por la boca. El presente estudio tuvo como objetivo verificar la influencia de un programa de ejercicios respiratorios de corta duración en la capacidad respiratoria de niñas en edad escolar. Se seleccionaron catorce alumnas de entre 8 y 10 años, de esta selección se conformaron dos grupos, el grupo control (GC) con 7 niños y el grupo experimental (GE) con 7. Mediante una prueba espirométrica, una evaluación de la capacidad respiratoria (ABC) se llevó a cabo para ambos grupos. El GE participó en un programa de ejercicios respiratorios (BEP) que duró de 15 a 20 minutos durante 5 semanas. Luego, se realizó nuevamente el ABC para ambos grupos. Los resultados demuestran un aumento significativo en los valores (p <0.01) de la capacidad vital forzada (FVC) del GE, sugiriendo así que la aplicación de un BEP promueve la capacidad respiratoria de las niñas en edad escolar. Se deben realizar más estudios con muestras más grandes y con un protocolo más extenso.
