Abstract
We examined the cardiorespiratory responses of 16 patients with postpoliomyelitis sequelae to a 16-week aerobic exercise program. The patients exercised at 70% of maximal heart rate. Dependent variables were resting and maximal heart rates, systolic and diastolic blood pressures, maximum oxygen consumption, maximum carbon dioxide consumption, respiratory quotient, and maximum expired volume per unit time. The exercise group was superior to the control group in watts, exercise time, maximum expired volume per unit time, and maximum oxygen consumption. No untoward events or loss of leg strength occurred as a result of the exercise regimen. We conclude that the aerobic training program employed in this study is a safe, short-term procedure and that patients with postpolio sequelae respond to training in a manner similar to healthy adults.
