【 摘 要 】

Maximum inspiratory pressure (MIP) has been used as an indicator of inspiratory muscle strength. Nevertheless their values show a high variability (~20%). The aim of this study was to determine the MIP, according to three protocols in young subjects. An observational cross-sectional study was carried out on a convenience sample of 60 students, 30 men (19.2 ± 0.81 years-old) and 30 women (19.17 ± 0.91 years-old). MIP was evaluated according to the protocol defined for each group of 20 participants of both genders: Group 1: American Thoracic Society/European Respiratory Society (ATS/ERS); Group 2: Learning; Group 3: Warming. For the analysis we used descriptive and inferential statistics, a p value < 0.05 was considered significant. No differences in MIP were found for the three best averages between groups (p = 0.078). When comparing the total performance of MIP replicates G3 was higher than G1 and G2 (p <0.0001). The coefficient of variation was higher in G2. It is concluded that the warming protocol (G3) could mitigate the effect of learning.
