운동생리학 : 운동경험과 장애유무가 상지운동시 심혈관 반응에 미치는 영향 = The effects of exercise and disability on cardiovascular responses in upper body exercise

다국어 초록 (Multilingual Abstract)

The purpose of this study is to analyze the effects of exercise and spinal cord injury on the cardiovascular responses and cardiac functions. Cardiovascular parameters were measured during graded maximal exercise test with arm ergometer. Cardiac functions were measured during rest with two-dimensional echocardiography on left-side lying body position.HRpeak, oxygen uptake, ventilation, oxygen pulse, LVIDd, IVSd, SV, EF, LV mass were examined in spinal cord injured wheelchair basketball athletes(PA, N=10), spinal cord injured sedentary group(PS, N=10), able-bodied wheelchair basketball athletes(AA, N=10), able-bodied sedentary group(AS, N=10).All data were expressed in means and standard deviation. We tested two-way ANOVA between exercise and spinal cord injury.The results of this study are following:1. Sedentary lifestyle of spinal cord injury was negative effects on cariovascular factors(HRpeak, oxygen uptake, ventilation, oxygen pulse), and cardiac factors(LVIDd, IVSd, SV, EF, LV mass).2. Regular exercise was positive effects on cariovascular factors(HRpeak, oxygen uptake, ventilation, oxygen pulse), and cardiac factors(LVIDd, IVSd, SV, EF, LV mass).In conclusion spinal cord injury and sedentary lifestyle lead to reduction of cardiovascular, cardiac function, physical fitness, physical work capacity. The concomitant increase of cardiovascular risk factors leads to a higher incidence of diseases of the cardiovascular system.On the other hand, regular physical activity leads to overcome of disability and vigorous lifestyle. Physical activity, up to and including high-performance sport, plays and important role for spinal cord injured during the course of rehabilitation. The various demands of sports, strength, speed, endurance, flexibility, and coordination as well as the level of lesion or severity of injury need to be considered when choosing a form of physical activity in rehabilitation. Especially, wheelchair basketball imposes a positive physical stress on cardiovascular system and encouraged to rehabilitation or lifetime sports.
