Objetivo: Investigar a influência do treino dos músculos inspiratórios (TMI) na função pulmonar de atletas de hóquei em patins do género masculino. Metodologia: Onze atletas de hóquei em patins foram randomizados e alocados no grupo experimental (GE) ou grupo controlo (GC). Foram avaliados os volumes pulmonares, volume expiratório no primeiro minuto (VEF1), capacidade vital forçada (CVF) e pico de fluxo expiratório (PFE), na avaliação inicial e final através da espirometria. O GE (n=6) foi submetido ao TMI com threshold durante 4 semanas, 3 vezes por semana, realizando 30 repetições (30 RM) com 50% da pressão inspiratória máxima. Contudo o GC (n=5) não foi submetido a qualquer intervenção. Resultados: Nas características sociodemográficas e antropométricas não observamos diferenças significativas, assim como nos volumes pulmonares, VEF1, CVF, PFE e VEF1/CVF antes do TMI. Verificamos um aumento estatisticamente significativo do PFE (p=0.033) no GE após o TMI. Conclusão: O TMI com threshold parece ter influência no PFE em atletas de hóquei em patins. Futuros estudos randomizados controlados devem ser realizados para corroborar os resultados obtidos.
Purpose: Investigate the influence of inspiratory muscle training (IMT) on lung function of male roller hockey players. Methods: Eleven male roller hockey players were randomized and allocated in the experimental group (EG) or control group (CG). Forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and peak-expiratory flow (PEF) were assessed with spirometry, in the beginning and four weeks later. The EG (n=6) was submitted to an IMT using a threshold during 4 weeks, 3 times a week, for 30 repetitions with 50% of maximal inspiratory pressure. However, the CG (n=5) was not submitted to any intervention. Results: Baseline sociodemographic and anthropometric characteristics were not significantly different neither the pulmonary variables, FEV1, FVC and PEF. Significant increase on PEF (p=0.033) was found in the EG after IMT. Conclusion: IMT with threshold seems to have an influence on PEF in roller hockey players. Further controlled randomized studies are needed to corroborate the findings.
