Resumo
A lesão medular apresenta alterações nas funções autônomas e sensório-motoras, dentre as funções autônomas esta o comprometimento respiratório. Sabe-se que este comprometimento depende do nível de lesão da medula espinhal, pois há redução ou perda de inervação devido a lesão. A prática esportiva proporciona aumento do condicionamento respiratório seja qual for o nível de lesão. Esta pesquisa teve como objetivo avaliar a função e mecânica pulmonar de paratletas de ciclismo com lesão medular e verificar se possuem alterações. Método. Participaram da pesquisa 20 praticantes de ciclismo do sexo masculino, com idade entre 20 a 45 anos, sendo 12 atletas e 8 paratletas com lesão medular sendo nível de lesão entre C5 incompleta a T10 completa. Foi realizada uma ficha de avaliação, espirometria, oscilometria, manuovacometria e dinamometria. Resultados. Os paratletas apresentaram diminuição em CVF (p<0,05), VEF1 (p<0,05), PEF (p<0,05), VCIn ( p<0,01), MEF75% (p<0,05 ), Z5Hz(p<0,05) e R5Hz (p<0,05). Não houve diferença significativa entre os dois grupos nos parâmetros índice de Tiffeneau, de MEF 25%, de MEF 50%, Freq Res, X5Hz, PEMax , PIMax , oxido nítrico e força de preensão palmar. Conclusão. Paratletas de ciclismo possuem alteração da mecânica e função pulmonar diminuída devido comprometimento muscular, além de um padrão restritivo característico dessa população, contudo a prática do esporte regular parece minimizar as consequências das sequelas respiratórias fato observado na manutenção da força respiratória e de membros superiores e pelos níveis de oxido nítrico sugerindo a ausência de inflamação em vias aéreas.
The spinal cord injury presents alterations in the autonomous and sensorimotor functions, among the autonomous functions this is the respiratory compromise. It is known that this impairment depends on the level of spinal cord injury, as there is a reduction or loss of innervation due to injury. Sports practice increases respiratory conditioning whatever the level of injury. This research aimed to evaluate the pulmonary function and mechanics of cycling athletes with spinal cord injury and to verify if they have alterations. Method. Twenty male cyclists, aged between 20 and 45 years, participated in the research, being 12 athletes and 8 athletes with spinal cord injury, with an injury level between C5 incomplete and complete T10. An evaluation form, spirometry, oscillometry, manuovacometry and dynamometry were performed. Results. Parathletes showed a decrease in FVC (p <0.05), FEV1 (p <0.05), PEF (p <0.05), VCIn (p <0.01), MEF75% (p <0.05), Z5Hz (p <0.05) and R5Hz (p <0.05). There was no significant difference between the two groups in the parameters of Tiffeneau index, MEF 25%, MEF 50%, Freq Res, X5Hz, PEMax, PIMax, nitric oxide and handgrip strength. Conclusion. Cycling athletes have impaired mechanics and reduced lung function due to muscle impairment, in addition to a restrictive pattern characteristic of this population, however the practice of regular sport seems to minimize the consequences of respiratory sequelae, a fact observed in the maintenance of respiratory strength and upper limbs and nitric oxide levels suggesting the absence of airway inflammation.
