Relevance of the results respiratory muscle force assessment in adolescents with visual impairments in the Benjamin Constant Institute

Abstract

Objective: To compare the respiratory muscle strength (RMS) of adolescent students with visual impairment
from Benjamin Constant Institute (IBC) who only practice school Physical Education within Institute with
students who practice physical activities in addition to scholar Physical Education. Methods: An observational,
cross-sectional, descriptive study was performed, whose maximal inspiratory pressure (MIP) and maximal
expiratory pressure (MEP) measurements were performed by digital manovacuometry. The comparison of
variables between boys and girls was done by the Mann-Whitney test for numerical data and by the X2
test for categorical ones, with criterion of significance of p <0.05. Results: A total of 77 students were evaluated with a median age of 16 years, which 39 (50.65%) of them were male. The median MIP was 94 cm H2O and MEP 95 cm H2O. Conclusion: There was no significant difference between students who has been practicing physical activities out of school shift and those who has only been practicing Physical school Education.
