RESUMEN

Introducción: el ejercicio físico induce un incremento en el flujo arterial, la pletismografía por oclusión intermitente con strain gauge de mercurio en silastic permite estudiar las extremidades superiores e inferiores en hiperemia reactiva. Objetivos: determinar el flujo arterial en hiperemia reactiva de las extremidades superiores e inferiores en ciclistas, remerosy un grupo control. Material y métodos: estudiamos 10 ciclistas de alta competición, 10 remeros de alta competición y 10 sujetos de control mediante técnica de hiperemia reactiva midiendo el flujo arterial mediante pletismografía en extremidades superiores e inferiores. Resultados: no existieron diferencias significativas en los flujos basales. Mayores incrementos de flujo arterial en piernas de ciclistas y remeros, en los controles. Incrementos mayores de flujo arterial en brazos de remeros omparado con ciclistas y controles. Conclusiones: la técnica de hiperemia reactiva medida por pletismografía es de fácil aplicación, mínimamente invasiva y sus datos son reproducibles. Existe un mayor incremento en el flujo arteria en hiperemia reactiva en extremidades superiores e inferiores en los deportistas y es mayor en las extremidades que se ejercitan más por el tipo de deporte.Deben de realizarse más estudios comparativos entre grupos sanos condiferentes riesgos para padecer enfermedades cardiovasculares.
