Objetivo: Determinar os efeitos do treino muscular inspiratório (TMI) na função pulmonar de
jogadores de rugby. Metodologia: Quarenta e quatro jogadores de rugby foram randomizados
e alocados em grupo experimental (GE) (n=22) ou grupo controlo (GC) (n=22). Em ambos os
grupos foram avaliados os parâmetros de volume expiratório forçado no primeiro segundo
(VEF1), capacidade vital forçada (CVF), pico de fluxo expiratório (PFE) e índice de Tiffeneau
(VEF1/CVF) através da espirometria, no ínicio do estudo e após 4 semanas. O GE (23,0 ± 4,2
anos) foi submetido ao TMI recorrendo a um threshold durante 4 semanas, 3 vezes por semana,
onde foi submetido a 30 repetições máximas (RM), com 50% da pressão inspiratória máxima,
enquanto o GC (23,2 ± 3,8 anos) não foi submetido a qualquer intervenção. Resultados: Nas
características sociodemográficas e antropométricas não observamos diferenças significativas
entre os grupos, assim como nos volumes pulmonares, com excepção do VEF1, no ínicio do
estudo. Verificamos um aumento estatisticamente significativo do VEF1, CVF, PFE e
(VEF1/CVF) no GE (p<0.05) e nenhum no GC, após o TMI. Conclusão: A aplicação do TMI
através do threshold parece produzir efeitos positivos sobre a função pulmonar dos jogadores
de rugby.
Purpose: Determine the effects of inspiratory muscle training (IMT) on the lung function of rugby players. Methods: A sample of 44 rugby players were included and divided into two groups, experimental (EG) (n=22) and control (CG) (n=22). Spirometry tests were performed on the two groups at an initial time and four weeks after, respectively. The parameters of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and Tiffeneau index (FEV1/FVC) were measured. The EG (23,0 ± 4,2 years) underwent inspiratory muscle training (IMT) using a threshold for 4 weeks, 3 times a week, where they were submitted to 30 repetitions (RM), with 50% of maximal inspiratory pressure. However, the CG (23,2 ± 3,8 years) was not submitted to any intervention. Results: Baseline sociodemographic and anthropometric characteristics were not significantly different between the groups as well as pulmonary volumes with the exception of VEF1 at the beginning of the study. There was statistically significant increase in FEV1, FVC, PEF and (FEV1/FCV) in EG (p<0.05) and none in CG after IMT. Conclusion: The application of IMT through a threshold in rugby players seems to have positive effects on the rugby players lung function.
