The sniff nasal inspiratory pressure (SNIP) is a simple and noninvasive technique use to assess inspiratory muscles strength. Reference values have been previous established for SNIP in adults but no previous studies have provided reference values for SNIP in adult Brazilian population. The main objective of this study were propose reference values of SNIP for Brazilian population through establishment of relationship between anthropometric measurements, physical activity profile and SNIP and at the same time compare the values obtained with reference values previously published. We studied 117 subjects (59 male and 58 female) distributed in different age grouped 20-80 years old. The results showed on significant positive relationship between SNIP and height and negative correlation with age (p<0.05). In the multiple linear regression analysis only age continued to have an independent predictive role for the two dependent variables that correlated with SNIP. The values of SNIP found in Brazilian population were higher when compared with predict values of previous studies. The results of this study provide reference equations of SNIP for health Brazilian population from 20 to 80 years old / Os testes de avalia??o da fun??o muscular respirat?ria como as medidas de press?o respirat?ria m?xima (Press?o Inspirat?ria m?xima - PIm?x e Press?o Expirat?ria m?xima - PEm?x) s?o testes cl?ssicos de for?a muscular respirat?ria, por?m alguns indiv?duos podem expressar certa dificuldade para a execu??o dessas manobras. A Press?o Inspirat?ria Nasal Sniff (Sniff Nasal Inspiratory Pressure - Pnsn), por se tratar de uma t?cnica f?cil e n?o-invasiva, tem sido utilizada para avaliar a for?a muscular inspirat?ria. Alguns estudos determinaram valores de refer?ncia de Pnsn em adultos, por?m n?o h? relatos na popula??o brasileira. Os principais objetivos desse estudo foram propor equa??es de refer?ncia para Pnsn na popula??o brasileira para homens e mulheres, a partir da investiga??o da rela??o entre Pnsn e idade, peso, altura, ?ndice de Massa Corp?rea - IMC e padr?o de atividade f?sica habitual, bem como avaliar a Pnsn numa amostra de volunt?rios saud?veis e comparar com os valores preditos em outras popula??es. A amostra foi composta de 117 indiv?duos (59 homens e 58 mulheres), estratificados em grupos et?rios entre 20-80 anos. Os resultados evidenciaram valores significativamente maiores da Pnsn com o aumento da altura e significativamente menores com o aumento da idade (p<0,05). Ao analisar as equa??es de regress?o linear m?ltipla, apenas a idade permaneceu exercendo influ?ncia na predi??o da Pnsn e os valores obtidos de Pnsn foram superiores quando comparados aos valores preditos em outras popula??es adultas. Nesse contexto, sugere-se equa??es preditivas para Pnsn em indiv?duos brasileiros saud?veis na faixa et?ria entre 20 e 80 anos, com o intuito de minimizar discrep?ncias diagn?sticas ao comparar indiv?duos
