The purpose of this study is to investigate the cardiopulmonary function and the energy metabolism of stroke patients and normal persons of graded load exercise using lower ergometer. Targeting 11 normal persons(male: 6, female: 5) and 9 stroke patients (male: 4, female: 5), an graded load exercise was performed with the use of lower ergometer by increasing 25 watts every 6 minute and Quark $b_2$ were used for the cardiopulmonary function and the energy metabolism. With respect to normal persons, there were significant increases in the phase of graded load exercise, maximum oxygen uptake time, exercise time with respect to the cardiopulmonary function. In addition, there was a significant correlation between cardiopulmonary function and energy metabolism, but there was no significant difference energy metabolism. As a result, there were no significant differences between stroke patients and normal persons of the cardiopulmonary function and the energy metabolism within 18 minutes, but it had significant differences between maximum oxygen uptake and exercise time. Moreover, it was possible to identify that the cardiopulmonary function and the energy metabolism of stroke patients and normal persons are related with maximum oxygen uptake.
