Determinação das equações dos valores de referência para a população do estado de São Paulo no teste incremental respiratório de endurancedos efeitos do treinamento resistido associado a fotobiomodulação

Abstract

Introduction - Respiratory evaluation methods include tests for both anatomical and functional changes, among which spirometry, which evaluates lung function and manovacuometry for respiratory muscle strength, are highlighted. Since the mid-1990s, the incremental respiratory endurance test (TIRE) was developed, which gives us a better evaluation of respiratory muscle status and this test had not been applied in individuals of the Brazilian population. Objective - The main objective of this study was to develop normal values for MIP (maximal inspiratory pressure), SMIP (sustained maximum inspiratory pressure) in Jaules (J) and units of time pressure (ptu) and ID (inspiration duration) by the TIRE. Methodology - 120 volunteers from the Brazilian population were studied, with no obstructive, restrictive or mixed ventilatory alterations demonstrated by previous spirometry, from 20 to 80 years old, 10 men and 10 women each decade. A prospective study of measurement of MIP, SMIP and ID, using the RT2 device (DeVilbiss Healthcare Ltda), and analogue manovacuometry. Results - The following equations were created. For MIP - Men + Women (Weight x 0.46) + (Gender x 23.63) + 72.20; Men (Weight x0.59) - (Age x 1.20) + 95.93; Women (Height x 85.86) - (Age x 0.66) - 51.06; For SMIP (J) - Men + Women (Heigth x 25.34) + (Gender x 3.50) - (Age x 0.06) - 32.90; Men (Height x 46.14) - 68.40; Women (Height x 16.21) - 21.19; SMIP Area (ptu) - Men + Women (Height x 1032.20) + (Gender x86.90) - 1410.60; Men (Height x 1457.00) - 2060.50; Women (Height x 595.80) - 711.90; ID (s) - Men + Women (Height x 11.00) - 9.50; Men (Height x 12.11) - 11.50; Women (Height x 14.90) - 15.80. Conclusion - The results of this study allowed us to form reference equations for the IMR (muscular inspiratory force) and EMR (respiratory muscle endurance) normal values for individuals of the Brazilian population, allowing an improvement in the evaluation of strength and, especially, endurance of respiratory muscles in different clinical situations.
