Evaluation of Cardiorespiratory Function by a Graded Cycling Exercise Test in Obese and Non-obese Stroke Hemiparetic Patients

摘要

Using a graded cycling exercise test, the Cardiorespiratory responses were examined in 43 stroke hemiparetic inpatients with or without obesity. These responses were also examined in 17 simple obese subjects. The following results were obtained: 1)Peak oxygen uptake (VO_2 peak) and peak heart rate (HR peak) were not significantly different in these three groups. 2) Peak oxygen uptake per body weight (VO_2 peak/W) in obese hemiparetic patients was significantly lower than that in the others. 3) Peak metabolic equivalent (METS peak) in obese hemiparetic patients was significantly lower than that in simple obese subjects. 4) Percentage of maximum oxygen uptake (% VO_2 max.) and peak load per body weight (Load peak/W) in hemiparetic patients were significantly lower than that in simple obese subjects. 5) Other indices such as percentage of maximum heart rate (% HR max.), peak minute ventilation (VE peak), % vital capacity (% VC) and forced expiratory volume at one second (FEV 1.0 sec.) were not significantly different in these three groups . And also, oxygen uptake (VO_2), heart rate (HR) and oxygen uptake per body weight (VO_2/W) at the anaerobic threshold were not significantly different. These results suggest that the physical fitness in hemiparetic patients is relatively lower than that in simple obese subjects, and VO_2 peak/W in obese hemiparetic patients is particularly lower than that in non-obese ones. Thus, attempts to improve the low fitness by both exercise and diet therapy might be particularly necessary for the better recovery of obese hemiparetic patients in the rehabilitation program.
