The purpose of this study was to compare cardiopulmonary function, RPE(Rating of perceived exertion), and blood lactate when examining the GXT(Graded exercise testing) of wheelchair treadmill and arm ergometer. Participants were 11 wheelchair basketball players with non disability. While examining the GXT of wheelchair treadmill and arm ergometer, cardiorespiratory functional capacity was measured by using $Quarkb^2$ and Polar and RPE was measured through Borg Scale. The lactate analyser, YSI-2000 was used to measure blood lactate level when resting, right after exercise, two minutes, four minutes, six minutes, and ten minutes of recovery. Data was analyzed by paired t-test using SPSS 18.0 program and significance for all statistical analysis was fixed at .05 confidence level(p<0.05). The conclusion of this study is below. First, maximal oxygen uptake which is a factor of cardiopulmonary function showed the highest with arm ergometer, the rate of respiratory exchange showed the highest with wheelchair treadmill, and maximal heart rate showed the highest with wheelchair treadmill. Second, subjective exercise intensity showed the highest with arm ergometer at the end point. Third, blood lactate level showed the highest with arm ergometer right after exercise.

The purpose of this study focused how to show physiological responses comparing exercise group and non exercise group for progressive maximal wheelchair ergometer exercise loading in complete paraplegia. It also examined the various factors which would be influenced physiological responses. Sixteen subjects have been investigated in this study, and the subjects are divided into two groups as follows: 1) exercise group (7 subjects) 2) non exercise group (9 subjects). Each test was terminated by physical exhaustion and/or an inability to maintain a flywheel velocity. The results were as follows: 1) No difference was noted in pulmonary function test between two groups. 2) $\dot{v}$ Emax value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ Emax of exercise group was $69.67{\ell}/min$, non exercise group was $41.47{\ell}/min$. 3) $\dot{v}$ $O_2max$(${\ell}/min$) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$(${\ell}/min$) of exercise group was $1.72{\ell}/min$, non exercise group was $1.15{\ell}/min$. 4) $\dot{v}$ $O_2$ max(ml/kg/min) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$($ml/kg{\cdot}min$) of exercise group was $25.99ml/kg{\cdot}min$, non exercise group was $18.61{\ell}/min$. 5) Maximal heart rate(HRmax) value during maximal exercise was significantly different between the groups (p<0.05). The mean HRmax of exercise group was 180.43 beats/min, non exercise group was 175.00 beats/min. 6) $\dot{v}\;E/\dot{v}\;O_2$ value during maximal exercise was not significantly different between the groups (p>0.05). The mean $\dot{v}\;E/\dot{v}\;O_2$ of exercise group was $36.36{\ell}/{\ell}\;O_2$, non exercise group was $45.46{\ell}/{\ell}\;O_2$. Considering the results which explore the exercise group with paraplegia has shown the maximal aerobic power compared with non exercise group, regular and consistent physical training is highly assumed as a main factor to improve cardiopulmonary fitness.
