Abstract des Autors

Principles for evaluating the functional capacity of, and, therefore, exercise testing, chronically-disabled populations such as individuals with a history of poliomyelitis are considerably less well established than those for able-bodied persons. Therefore, we examined the use of indexes of movement economy and cardiorespiratory conditioning based on the results of a submaximal exercise test and oxygen consumption studies in individuals with a history of poliomyelitis. Subjects (n=48) were categorized into four distinct groups, ie, having normal movement economy and either normal (n=12) or reduced cardiorespiratory conditioning (n=11), or having reduced movement economy and either normal (n=10) or reduced cardiorespiratory conditioning (n=15). There was no relationship between the indexes of movement economy and cardiorespiratory conditioning supporting that these indexes reflected physiologically-distinct entities. Irrespective of movement economy, deconditioned sujects had a reduced forced vital capacity (% predicted) and a higher resting heart rate (HR) compared to conditioned subjects. The difference in resting HR was attributed to conditioning level rather than initial arousal because resting HR and VO2 were comparable on repeated tests. Although there was no difference in steady-state (HR (% predicted maximum) among the four groups, VO2 (% pred max) was significantly lower for the deconditioned than the conditioned subjects.
