  • 본 연구에서는 광전 용적맥파(photoelectric plethysmography, PPG)를 기반으로 이를 이용하여 혈관 탄성도를 측정 할 수 있는 시스템에 관하여 연구하였다. 광전 용적맥파는 광을 이용한 비 침습적 맥파 측정 방식으로 손가락 끝 부분에서 측정하고 혈액 내에 헤모글로빈의 빛에 대한 광 흡수도의 차이로 인해 나타나게 된다. 얻어진 신호를 2차 미분 하게 되면 가속도 맥파 (acceleration photoplethymogram, APG)를 얻을 수 있고 이는 혈관 탄성도의 추정에 응용가능하다. 본 연구에서는 혈관 탄성도를 측정하기 위한 방법으로 광전 용적맥파를 적용하여 가속도 맥파 측정기기를 설계하고, 이를 바탕으로 혈관 탄성도 추정에 적용 가능 여부를 연구하였다.

  • The body composition and arterial compliance with advanced age increase the risks of cardiovascular diseases, but the elderly can perform rhythm exercise easily, which may positively influence their body composition and arterial compliance. Therefore, this study examined the effects of rhythm exercise training on the body composition and arterial compliance in elderly females. The subjects (n=20) were assigned randomly to either an exercise group (n=10, EX) or non-exercise control group (n=10, CON). The rhythm exercise training for 12 weeks consisted of 3 sessions per week with 60 minutes per session. In addition, the intensity was set to 11-14 of the Borg scale (6-20). The body composition and arterial compliance (pulse wave velocity (PWV)) were measured before and after training. The skeletal muscle mass in the EX was increased significantly (p=0.04) and the right (p=0.002) and left side (p=0.02) of the PWV in the EX were decreased significantly, but the skeletal muscle and both sides of the PWV in the CON were not changed. Elderly females could easily perform rhythm exercise training, which resulted in improvements of the skeletal muscle mass and arterial compliance. Therefore, rhythm exercise training may prevent or delay sarcopenia and reduce the risk of cardiovascular diseases.

  • Both cardiovascular diseases caused by decreased body composition and arterial compliance and falling induced by loss of muscle mass are frequent occurrences in the elderly. Therefore, elderly people are advised to perform elastic band resistance exercises to improve their body composition and arterial compliance. Thus, the purpose of this study was to examine the effects of 12 weeks of elastic band resistance training on the body composition, arterial compliance and falling index in elderly females (> 65 years). The elastic band resistance exercise program was administered 3 times per week for 60 minutes each time for 12 weeks. In addition, the exercise intensity was set to 11-14 on the Borg scale (6-20). Before and after the training period, the body composition (body weight (BW), muscle mass, % body fat, body mass index (BMI)), arterial compliance (ankle brachial index (ABI) and pulse wave velocity (PWV)) and risk of falling index were determined. (After the program?), the BW (p=.003), BMI (p=.002), PWV (p=.017) and risk of falling (p=.037) in the exercise group were significantly reduced, whereas the BW (p=.009) and BMI (p=.009) in the control group were significantly increased. In conclusion, the body weight, BMI and arterial compliance of elderly females were positively changed by the elastic band resistance training. Thus, the elastic band resistance exercise may be useful for elderly people to prevent metabolic syndrome and cardiovascular diseases and to reduce their risk of falling.

  • 우리나라의 당뇨병 유병률은 경제발전과 식생활의 급속한 서구화로 빠른 속도로 증가하고 있다. 특히 당뇨병은 유병기간이 길수록 여러 합병증을 초래하는데 그 중 하나가 혈관경화증이다. 혈관 경화증은 신체 부위별로 그 진행 속도가 다르다. 광혈류측정법(PPG, photoplethysmogram)은 간편한 혈류량 측정방법으로 PPG 2차 미분 방법을 이용해서 혈관의 경화도를 진단할 수 있다. 이러한 PPG 2차 미분방법을 이용하여 당뇨병환자의 왼손과 오른손의 말초혈관 탄성도 차이를 정상인과 비교해 보았다. 실험결과 당뇨병환자와 정상인의 양 손가자 말초혈관 탄성도의 유의한 차이를 확인 할 수 있었다.

  • The purpose of this study was to investigate the effect of aerobic exercise training and half bath on blood component, cardiorespiratory function, and vascular compliance of middle-aged obese men. The subjects were 3 groups; aerobic exercise(n=10), half bath(n=10), and controlled group(n=10). They were tested on their blood component, cardiorespiratory function, and vascular compliance at the beginning and at the end of the 12-week study(pre-post test). For data analysis, mean and standard deviation scores were calculated, and repeated measure two-way ANOVA and Scheffe were used. The results of this study are as follows. First, aerobic exercise group was significantly improved on all blood component after the 12-weeks, and showed significant difference among groups. Half bath group was better than control groups on Triglyceride, LDL-C, and HDL-C levels. Second, aerobic exercise group was significantly improved on maximum oxygen uptake, maximum heart rate, and maximum ventilation after the 12-weeks. Third, in vascular compliance measured in both hands and both feet, the half bath group and aerobic exercise training group were significantly increases the control group. Therefore, these results imply that aerobic exercise and half bath can be helpful for better blood component, cardiorespiratory function, and vascular compliance in middle-aged obese men.

  • Recently the prevalence rate of diabetes in Korea has been increasing rapidly due to high growth of economy and changes in dietary lifestyle. Vascular complication is one of diabetic complications which have frequently occurred by obesity, hyperglycemia and impaired glucose metabolism. Photoplethysmogram(PPG) measured from finger and toe is very useful for evaluation of vascular aging and sclerosis level since the PPG signal represents characteristics of peripheral vascular Several researchers have reported that second derivative of the finger PPG waveform was useful to evaluate vascular compliance and developed various analysis methods for vascular compliance. However, peripheral vascular compliance study for diabetic patient was never evaluated by using second derivative of PPG. Therefore, we aimed to objectively compare and to assess normal(n=850) and diabetic(n=50) groups vascular compliance using the second derivative of PPG waveform in this study. The evaluated factors of the second derivative of PPG are 'a', 'b', 'c', 'd', 'e' and b/a rapresents vascular compliance. This study found out that when vascular compliance is decreased, the absolute value of b/a is decreased. The average vascular compliance of 50 diabetic patients with neuropathy, $-1.09{\pm}0.14$ is statistically lower than the normal group, $-0.81{\pm}0.09$ (p<0.05). In conclusion, we suggest an objective evaluation of peripheral vascular compliance for diabetic patients and prevention of vascular complication.
