This study aims to examine the correlation among adiponectin, cardiorespiratory fitness and metabolic syndrome risk factors, according to medium(6MET's) to high levels of physical activity in the elderly. Total 115 subjects worn Sense Wear Armband (USA) for 7 days and it measured the time they do physical activity at 6MET's or more (min/week). As it compared and analyzed the correlation among diponectin, cardiorespiratory fitness and metabolic syndrome risk factors according to physical activity levels, it concluded the followings. First, when it compared body composition, lipid, glucose, adiponectin, maximal oxygen uptake (VO₂max) depending on physical activity levels, glucose concentration was higher in B group than in C and D groups (p<.05); the level of adiponectin was significantly lower in C and D groups which show high levels of physical activity than in the group with low level of physical activity (p<.05); and VO₂max was significantly higher in D group which presents the highest level of physical activity, compared to A and C groups (p<.05). Second, in regard to the correlation among adiponectin, cardiorespiratory fitness and metabolic syndrome risk factors according to physical activity levels, %fat was positively correlated with BMI(r=0.692) and TG (r=0.403) (p<.05), but negatively correlated with VO₂max(r=0.330) (P<.05); BMI was positively correlated with TG(r=0.213) (P<.05), but negatively correlated with VO₂max(r=-0.268) (P<.05); TC was positively correlated with TG(r=-0.213) HDL(r=0.730) and LDL(r=0.848) (P<.05); TG was negatively correlated with LDL (r=-0.223) and VO₂max(r=-0.275); HDL was positively correlated with LDL(r=0.582) (P<.05); and glucose was positively correlated with adiponectin(r=0.18) (p<.05). It presented that medium(6MET?s) to high levels of physical activity in the elderly are correlated with metabolic syndrome risk factors and that high cardiorespiratory fitness positively affects such risk factors. Therefore, it may be required to steadily do exercise at medium(6MET?s) to high levels to maintain and improve cardiorespiratory fitness.

이 연구는 여자 비만 청소년들의 신경영양성인자와 연관된 심폐체력과 우울증 증후, 혈중 BDNF (brain-derived neurotrophic factor), 심혈관질환 위험요인과의 관계를 밝혀 비만 여자청소년들의 뇌 건강 예방 및 치료를 위한 변인들이 가지는 의미를 연구하는데 목적이 있다. 여자 중학생 19명(연령 15.0±0.82 세, BMI 30.66±1.88 kg/m2)이 연구에 참가하였다. 심폐체력과 우울징후 (r=-0.57, p<0/05), 혈중 콜레스테롤 (r=-0.54, p<0.05), 중성지방 (r=-0.47, p<0.05), 저밀도 지단백 콜레스테롤(r=-0.72, p<0.05), 글루코스 (r=-0.65, p<0.05)는 유의한 역상관을 보여주었고, 심폐체력과 혈중 안정 시 BDNF(r=-0.49, p<0.05)와 고밀도 지단백 콜레스테롤 (r=0.59, p<0.05)은 유의한 정상관을 보여주었다. 심폐체력 1ml/kg/min의 증가는 안정 시 혈중 BDNF 0.49ng/ml를 유의하게 증가시켰으며, 심폐체력 1ml/kg/min의 증가는 우울징후 점수 0.47을 유의하게 감소시키는 것으로 나타났다. 심폐체력과 심혈관 질환 위험요인 관련성에 대한 보다 심층적인 연구가 필요하며, 혈중 BDNF 뿐 아니라 혈소판, 근육에 내재된 BDNF 수준도 같이 고려하는 연구가 필요한 것으로 보여 진다. The purpose of this study was to examine the relationship in cardiorespiratory fitness, depression symptoms, blood BDNF (brain-derived neurotrophic factor), and cardiovascular disease in female obese adolescents. Forty-eight female adolescents were participated in this study (age 15.0±0.82 yrs, BMI 30.66±1.88 kg/m2). Cardiorespiratory fitness was negatively associated with depression symptoms(r=-0.57, p<0/05), blood cholesterol(r=-0.54, p<0.05), triglyceride(r=-0.47, p<0.05), low density lipoprotein(r=-0.72, p<0.05), and glucose(r=-0.65, p<0.05), respectively. Cardiorespiratory fitness was positively associated with resting blood BDNF(r=-0.49, p<0.05) and high density lipoprotein(r=0.59, p<0.05). Regression data showed that an increase by 1ml/kg/min in cardiorespiratory fitness significantly increased blood BDNF by 0.49ng/ml and significantly decreased depression symptoms by 0.47 point. Future search is needed to determine cardiorespiratory fitness and cardiovascular disease risk factor as well as considering platelet and muscle BDNF levels.

The aim of this study was to examine difference in physical characteristics, lifestyle factors, isokinetic strength, and physical fitness between rural and urban older residents in Korea. Urban older residents were voluntarily recruited in Seoul, Korea, and rural older residents were voluntarily recruited in Yong-gwang, Jyulado which is one of the most rural areas. All isokinetic strength factors, including extension peak and average powers and flexion peak and average power, were measured using IsoMed 2000, bioelectrical impedance equipment was used to measure muscle mass, fat free mass(FFM), total body fat mass(TBF), and % fat mass(%FM). All the participants were questioned by one interviewer who checked their questionnaires, and their weight and height were also measured. There was no significant difference in the lifestyle factors between two resident areas, but significant differences in LS and SS were found between two groups(p<0.05). Significant differences in BMI(p<0.001), %FM(p<0.01), physical activity level(p<0.001), and all power factors(p<0.001) were observed between urban and rural older adults. These findings suggest that, there are significant differences between rural and urban areas in shoulder powers, body components, exercise habit, and BMI.
