Introduccion: La frecuencia cardiaca (FC) ha sido tradicionalmente utilizada para regular la intensidad del ejercicio, sin embargo, presenta limitaciones para su cuantificacion sin un monitor cardiaco. En consecuencia, metodos indirectos, como el Talk Test (TT), han sido validados en adultos, no asi en poblacion infantil. El objetivo de este estudio fue determinar la relacion entre el TT y los metodos objetivos para cuantificar la intensidad del ejercicio en ninos sanos chilenos. Metodos: Se considero a ninos sanos de ambos generos entre 8 y 12 anos. Los sujetos realizaron dos pruebas de ejercicio incremental en escalon separadas por 7 dias. El TT se incorporo en una de las dos pruebas aleatoriamente. Se midio la FC, percepcion del esfuerzo (PE) y carga de trabajo, cada un minuto durante la prueba. Se comparo la FC, PE y carga de trabajo entre la respuesta positiva (TT+/+), equivoca (TT+/-) y negativa (TT-/-) del TT. Adicionalmente, se determino la confiabilidad de los parametros cardiorrespiratorios durante el TT. Un valor de p<.05 se considero significativo. Resultados: Ingresaron 48 sujetos, edad 9.7±1.1 anos. Existio diferencia significativa en los parametros cardiorrespiratorios entre las respuestas del TT (p<.0001). El % de la FC maxima en TT+/+ fue 72.2 ± 8.2, en TT+/- fue 87.9 ± 8.1 y en TT-/- fue 92.0 ± 7.5%. La confiabilidad de los parametros cardiorrespiratorios durante el TT fue regular a excelente en ambos generos. Conclusiones: El TT se relaciono con los parametros cardiorrespiratorios para regular la intensidad del ejercicio en ninos sanos. Abstract. Introduction: Heart rate (HR) has traditionally been used to regulate the intensity of exercise; however, its measurement is limited in the absence of a heart rate device. Consequently, indirect methods, such as the Talk Test (TT), have been validated in adults, yet not in children. The objective of this study was to determine the relationship between TT and objective methods to quantify the intensity of exercise in healthy Chilean children. Methods: Healthy children of both genders aged between 8 and 12 years old were considered for the study. The participants performed two incremental step exercise tests separated by 7 days. The TT was incorporated in one of the two tests randomly. The HR, effort perception (EP) and workload were measured every one minute during the test. HR, EP and workload were compared by positive (TT + / +), equivocal (TT +/-), and negative (TT - / -) response of the TT. Additionally, the reliability of cardiorespiratory parameters during TT was determined. A value of p <0.05 was considered significant. Results: 48 participants aged 9.7 ± 1.1 years old were selected. There was a significant difference in cardiorespiratory parameters between the TT responses (p <.001). The percent of maximum HR in TT + / + was 72.2 ± 8.2%, in TT +/- was 87.9 ± 8.1% and in TT - / - was 92.0 ± 7.5%. The reliability of cardiorespiratory parameters during TT was fair to excellent in both genders. Conclusions: TT was associated to cardiorespiratory parameters to regulate exercise intensity in healthy children.
