Cardiorespiratory responses to upper extremity aerobic training by postpolio subjects.
The cardiorespiratory responses of ten postpolio subjects participating in a 16-week upper extremity aerobic exercise program were compared to ten non-exercised controls. The subjects trained three times a week for 20 minutes per session. Exercise intensity was prescribed at 70% to 75% of heart rate reserve plus resting heart rate. Dependent variables were resting heart rate, maximal heart rate, resting and immediate-post-exercise systolic and diastolic blood pressures, maximal oxygen consumption, maximal carbon dioxide production, minute ventilation, respiratory exchange ratio, power, and exercise time. After training, the exercise group was superior to the control group in oxygen consumption, carbon dioxide production, minute ventilation, power, and exercise time. There was no reported loss of muscle strength. It was concluded that postpolio subjects can safely achieve an increase in aerobic capacity with a properly modified upper extremity exercise program. This improvement is comparable to that demonstrated by able-bodied adults.
