국문 초록 (Abstract)

본 연구의 목적은 뇌병변 장애인을 대상으로 8주간의 유산소성 체조활동을 실시하여 신체조성, 체력 및 염증반응지표의 변화에 대하여 알아보는 것이다. 본 연구의 피험자는남·녀 뇌병변장애 중 대표적인 뇌졸중 장애인 17명을 대상으로 시작되었지만 9명이 중도포기하여 최종 8명이 참가하였다. 운동 프로그램 참여 전 사전 검사를 실시하였으며, 기본적 변인으로 신장, 체중, Body Mass Index(BMI), 안정시 심박수, 안정시 혈압을 측정하고, 체력 변인으로는 체간 굴곡과 신전, 견관절 굴곡과 신전의 유연성과 악력을 통한근력, 폐활량을 통한 폐기능을 측정하였다. 또한 혈액성분으로는 혈중지질, 그리고 심혈 관질환 위험인자인 염증반응지표로서 C-reactive protein(CRP), Interleukin-6(IL-6), Tumor Necrosis Factor-α(TNF-α)를 분석하였다. 8주 유산소성 체조활동 프로그램은 매회50분씩 주 2회 실시하였으며, 운동강도는 운동자각도(RPE) 수준 13으로 유지하였다. 뇌병변 장애인의 유산소성 체조활동 프로그램 참여 후 운동의 효과를 검증한 결과 전체 집단에서 안정시 수축기혈압과 이완기혈압이 유의하게 감소하였다(p<.01). 또한 체력 요인에서는 체간 굴곡과 신전(p<.05), 건측의 견관절 굴곡과 신전(p<.01), 환측의 견관절 굴곡(p<.05)이 유의하게 증가하였다. 혈액 성분의 분석 결과 혈중지질에는 유의한 변화가 나타나지 않았으며, 염증반응지표의 경우 IL-6가 유의하게 감소하였고(p<.05), 유의하지는 않으나 CRP도 감소하는 경향을 나타냈다(p<.088). 결론적으로, 지속적이고 규칙적인 유산소성 체조활동은 뇌병변 장애인의 안정시 심박수와 혈압 및 체력을 개선시키는 효과가 있을 뿐만 아니라 심혈관질환의 위험요소로 알려져 있는 염증반응지표를 개선하는 데에도 긍정적인 영향을 주는 것으로 나타났다.

The purpose of this study was to analysis the effect of aerobic gymnastic exercise for eight weeks on physical fitness and inflammatory markers which are known as risk factors for cardiovascular diseases in hemiplegic disabled after cerebral stroke. For this purpose, stroke patients(n=8) participated in aerobic exercise training 2 days/week, 50 mins/day, for 8 weeks and maintained at 13 level of RPE. Body composition, resting heart rate and blood pressure were measured before physical fitness test. Trunk flexion/extension, shoulder flexion/extension, grip strength, pulmonary function were measured as physical fitness test. Blood sample of 15ml was drawn from antecubital veins for measuring inflammatory markers(c-reactive protein, interleukin-6, tumor necrosis factor-α). The result of this study is as follows: Resting blood pressure decreased significantly after 8-week aerobic exercise training in total stroke patients (p<.01). After completion of the aerobic exercise program, trunk extension/flexion(p<.05), shoulder extension/fexion(p<.01), were significantly improved in total stroke patients. There was no significant improvement on blood lipid profiles in total stroke patients. However, IL-6 was significantly improved in stroke patients after 8-week aerobic exercise(p<.05). In conclusion, These findings suggests that regular aerobic gymnastic exercise decreases resting heart rate and blood pressure, and improves physical fitness, inflammatory markers which are known as a risk factor of cardiovascular diseases in person with disability occurred due to hemiparetic stroke
