걷기운동이 공복혈당장애 및 제 2형 당뇨 노인의 혈중 당대사 지표와 지질대사 지표에 미치는 영향 = Effects of regular walking exercise on blood glucose and lipid profile in older adults with impaired fasting glucose and NIDDM

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effects of a regular walking exercise on blood glucose and lipid profile in older adults with impaired fasting glucose(IFG) and non-insulin dependent diabetes mellitus(NIDDM).Forty-three ambulatory older adults(? 65 yr, 34 men and 9 women) with either IFG or NIDDM, who had not taken medications, were recruited and randomly assigned to either a control(male=9, female=3) or walking exercise group(male=25, female=6). The control group received health education, and the walking exercise group received supervised walking exercise program (3day/wk, 30-60min, 200kcal/day consumption) with health education for 12 weeks.There were significant decreases in body mass index(BMI), %body fat, fat mass, and both systolic and diastolic blood pressures between control and walking exercise group(P<0.05). As well, there were significant reductions in blood levels of total cholesterol, triglyceride, glucose, and insulin, and homeostasis model assessment-insulin resistance(HOMA-IR) between control and walking exercise group. In addition, there were significant increases in lean mass, upper and lower body strength, muscular endurance, whole body endurance and maximal oxygen consumption between control and walking exercise group.In conclusion, these results are interpreted to mean that regular walking exercise in older adults with either IFG or NIDDM has beneficial effects on body composition, physical fitness, insulin resistance and risk factors for cardiovascular diseases.

본 연구의 목적은 규칙적인 걷기운동이 공복혈당장애 및 제 2형 당뇨 노인의 혈중 당대사지표와 지질대사지표에 미치는 영향을 규명하는 것이다.걷기운동이 가능하고 현재 약물치료를 받지 않는 43명의 공복혈당장애 및 제 2형 당뇨 노인들(? 65세, 남=34, 여=9)을 대상으로 하였고, 각각 걷기운동군(남=25, 여=6)과 일상생활군(남=9, 여=3)으로 무선배정 하였다. 일상생활군은 건강 교육 후 특별한 운동을 하지 않고 일상생활 패턴을 유지하였고, 걷기운동군은 건강 교육과 12주간 걷기운동(3day/week, 30-60min/day, 200kcal/day 소모)을 실시하였다.규칙적인 걷기운동은 걷기운동군(P<0.05)에서 BMI, 체지방률, 지방량, 혈압을 유의하게 감소시켰으며, 총 콜레스테롤, 중성지방, 혈당, 인슐린, HOMA-IR을 유의하게 감소시켰다. 또한, 근육량, 상체근력, 하지근력, 근지구력, 전신 지구력 및 심폐지구력이 유의하게 향상되었다.결론적으로, 규칙적인 걷기운동이 공복혈당장애 및 제 2형 당뇨 노인의 신체구성, 체력, 인슐린 저항성 그리고 심혈관계 질환 위험 요소에 긍정적인 영향을 준다고 해석된다.
