상·하지 점증 부하 최대운동이 성인 편마비 장애인의 심폐기능에 미치는 영향

The purpose of this study was to find the cardiopulmonary function between upper extremities by arm ergometer exercise and lower extremities by cycle ergometer exercise in adult hemiplegia. The subjects selected for the experiment were composed of 20 male and female(11 male adult hemiplegia, 9 male normal subjects). The subjects were given an explanation of all laboratory procedures before they consented They performed continuous incremental work load test by way of arm ergometer(Cybex MET300^TM, U.S.A.) and cycle ergometer(Cybex MET100^TM, U.S.A). They were warmed up with 60RPM at 0 watt for 2 minute and thereafter the work rate was gradually increased 12.5 watt every 2 minute and thereafter the work rate was gradually increased 12.5 watt every 2 minute until exhaustion in maximal arm ergometer exercise test. Also, They were pedalled with 60RPM at the begining with unloads for 2 minute and thereafter the work rate was gradually increased 12.5 watt every 2 minute until exhaustion in maximal cycle ergometer exercise test. Respiratory gas was analyzed by automated respiratory ags analyzer, Quinton(USA) every 20 second. Statistical techniques for data analysis were applied 2 way repeated measure ANOVA The 0.05 level of significance was used as the critical level for rejection of the null hypotheses for the study. On the basis of the results analyzed in this study, conclusions were drawn as follow 1) Significant differences in HRpeak were observed between the 2 groups (male adult hemiplegia and normal male on arm ergometer and cycle ergometer(p=0.001) during graded maximal exercise. 2) Significant differences in V0₂peak were observed between the 2 groups (male adult hemiplegia and normal male on arm ergometer and cycle ergometer(p=0.0002) during graded maximal exercise. 3) Significant differences in VO₂peak/kg were observed between the 2 groups (male adult hemiplegia and male normal on arm ergometer and cycle ergometer(p=0.0001) during graded maximal exercise.
