espanolLos desordenes neurologicos generan afectacion fisica y derivan en sedentarismo, enfermedades coronarias y obesidad o diabetes, reduciendo tanto la esperanza como la calidad de vida. La oferta de actividad fisica adaptada es escasa por falta de informacion especifica sobre la forma de adecuarlo y dosificarlo a las personas que presentan estos desordenes. Con el fin de comparar el efecto del ejercicio de pedaleo de brazos sobre la respuesta fisiologica y la percepcion del esfuerzo, en 8 personas con lesion medular, 4 con paralisis cerebral y 4 con ataxia de Friedreich, se analizo su respuesta fisiologica, asi como su percepcion subjetiva al esfuerzo, frente a un grupo Control (16 participantes). Para ello realizaron un ejercicio normalizado de pedaleo de brazos en un ergometro y se midieron frecuencia cardiaca, frecuencia respiratoria, volumen corriente, volumen espirado, consumo de Oxigeno relativo, pulso de Oxigeno y percepcion del esfuerzo. Se realizo un ANOVA con estas variables. Para el grupo con lesion medular, el estres y gasto energetico resultaron los mas bajos. El grupo con paralisis cerebral mostro los niveles de estres mas altos, ademas percibiendolo como una carga moderada. El grupo con ataxia de Friedreich, mostro respuestas cardiorrespiratorias altas intermedias. Se puede concluir que diferentes desordenes neurologicos muestran respuestas fisiologicas muy diferentes frente al ejercicio y es importante su control. EnglishNeurological disorders produce physical impairment that result in physical inactivity, heart disease and obesity or diabetes, reducing both life expectancy and quality of life. The supply of adapted physical activity is limited by lack of specific information on how to adapt and dose to people who have these disorders. In order to compare the effect of armcrank pedaling exercise on their physiological response and perceived exertion, 8 persons with spinal cord injury, 4 with cerebral palsy and 4 with Friedreich's ataxia were analyzed, comparing their physiological responses as well as their perceived effort, to a control group (16 participants). They performed a standardized armcrank pedaling exercise on an ergometer and heart rate, respiratory rate, tidal volume, expiratory volume, relative oxygen consumption, oxygen pulse and perceived exertion were measured. An ANOVA test was performed with these variables. For the group with spinal cord injury, stress and energy expenditure were the lowest, the group with cerebral palsy showed the highest levels of stress while perceived it as a moderate load. The group with Friedreich's ataxia showed medium high cardiorespiratory responses. In conclusion, it has been identified as different neurological disorders show very different physiological responses to exercise and the importance of their control.
