    • Abstract:
      Modified Shuttle Walk Test (MSWT) is a potentially maximal exercise test that, together with the assessment of respiratory muscle strength (RMS), reflects the respiratory condition and exercise capacity of schoolchildren with cystic fibrosis (CF). This study aimed to investigate the relationship between the RMS and the performance in the MSWT by schoolchildren with CF and to compare the data obtained with the values predicted in the literature. This is a cross-sectional observational study that included schoolchildren with CF. Anthropometric evaluation, spirometry and RMS evaluation were performed, using the maximal inspiratory (MIP) and expiratory (MEP) pressures (Globalmed MVD300® manovacuometer) (ATS/ERS) (2002). Two MSWT were performed, with an interval of 30 minutes between them. The distribution of the data by the Shapiro-Wilk test was applied and paired t-test was used to compare the values of the evaluations with those predicted, as well as for comparison between genders. Pearson test was used for correlation between MIP and MEP and the performance in the MSWT. Significance of 5% was accepted. 28 children (9.9±1.9 years) participated; 57.14% showed MIP below the predicted (15 children) and 53.57% showed MEP below the predicted (16 children). The mean performance was 730.4±266.1m, which is lower than the values predicted in the literature. No relationship between performance and RMS was observed. A moderate correlation was observed between MIP and MEP values (r=0.58, p=0.01). No relationship between the RMS and the MSWT performance was observed in schoolchildren with CF of this study. The RMS and the performance in the MSWT were below the predicted in the literature.
      El Modified Shuttle Walk Test (MSWT) es una prueba de ejercicio potencialmente máxima que, asociada a la evaluación de la fuerza muscular respiratoria (FMR), refleja la condición respiratoria y la capacidad de ejercicio de escolares con fibrosis quística (FQ). El objetivo de esta investigación fue investigar la relación entre FMR y distancia recorrida (DP) en el MSWT realizado por escolares con FQ y comparar los datos obtenidos con valores predichos en la literatura. Se trata de un estudio observacional transversal que incluyó a los escolares con FQ. Se realizó una evaluación antropométrica, espirometría y FMR, utilizando las presiones inspiratoria máxima (PImáx) y espiratoria máxima (PEmáx) por medio de la manovacuometría. Se realizaron dos MSWT, con un intervalo de 30 minutos entre ellos. Se verificó la distribución de los datos por la prueba de Shapiro-Wilk y se aplicó una prueba t pareada para la comparación entre los valores de las evaluaciones y el predicado, así como para la comparación entre los géneros. Se aplicó una prueba de Pearson para la correlación entre PImáx y PEmáx y DP en el MSWT. Se aceptó una significación del 5%. Participaron del estudio 28 niños (9,9±1,9 años); 57,14% presentaron PImáx por debajo del pronóstico (15 niños) y 53,57% por debajo del pronóstico para PEmáx (16 niños). El promedio de la DP fue 730,4±266,1m, por debajo del predicho en la literatura. No hubo relación entre DP y FMR. Se identificó una correlación moderada entre valores de PImáx y PEmáx (r=0,58 y p=0,01). No hubo relación entre FMR y desempeño en el MSWT en los escolares con FC. La FMR, así como la DP en el MSWT, se presentó abajo del predicho en la literatura.

Não houve relação entre FMR e desempenho no MSWT nos escolares com FC estudados. A FMR, bem como o DP no MSWT, apresentouse abaixo do predito na literatura.
