The purpose of this study was to analyse the effects of metabolic syndrome risk factor and blood lipids on b-aPWV in Obese middle-aged women. In order to achieve the objects, 38 middle aged women were included. All participants measured body composition by InBody 4.0(ver). The metabolic syndrome factors were body composition(BMI,FFM,%fat, WC, BW, WHR), Blood Lipids(TC, TG, HDL-C, LDL-C, Blood Glucose) and blood pressure. The b-aPWV was measured by Colin pulse Waveform Analyzer(VP-1000, Colin, Japan) All factors were analysed using multiple regression analysis(IBM SPSS 25). The main resulted of the study are as follows. First, b-aPWV of obesity middle aged women did significant effect by the body composition(WC, %fat, WHR) and diastolic blood pressure. Between b-aPWV and body composition(WC, %fat, WHR), diastolic blood pressure shows positive relationship. Second, b-aPWV of obesity middle aged women did significant effect by the blood lipids(HDL-C) and blood glucose. Between b-aPWV and HDL-C show negative relationship. But blood glucose show positive relationship. The results suggest that low metabolic syndrome risk factors(WC, %fat, WHR, diastolic blood pressure, blood glucose) and only high HDL-C may have positiv e effect for b-aPWV in obese middle-aged women

The purpose of this study was to examines the blood ammonia and lactate concentration changes following incremental maximal exercise. Secondary purpose of this study was to find correlation relationship between ammonia and lactate concentration. The subjects of this study were 10 normal healthy males and all subjects were involved in each test. Incremental maximal exercise tests were performed by each subject on a Monark cycle ergometer. VO2max was measured on the ergometer tests breathed through a low resistance low deadspace breathing valves using exercise protocol of ACSM. Plasma was sampled from an antecubital vein using a hypodermic syringe at rest, post-exercise(all-out), 30min after exercise and analyzed for whole blood ammonia and lactate. The results were as follows : 1. Blood lactate and ammonia concentration on incremental maximal exercise were increased linearly according to intensity of exercise, but remained elevated above resting values after 30min of recovery.2. Between blood lactate and ammonia after incremental maximal exercise were very low correlation(r=0.062), but recovery 30min was very high correlation of positive(r=0.908). It can be concluded that blood lactate and ammonia concentration are independent threshold each other in exercise.

The purpose of this study was to investigated the relationship for the application and the usefulness of canonical correlation analysis in cardiorespiratory function and regional body mineral density female Taekwondo player. The subjects participated in this experiment voluntary for this study were 19 healthy female Taekwondo player for about 8 years. The cardiorespiratory function were VO₂max(Maximal Oxygen Consumption), AT(Anaerobic Threshold), VEmax(Maximal Ventilation), RER(Respiratory Exchange Ratio) and HR(Rest Heart Rate). The cardiorespiratory function was measured by cardiopulmonary exercise testing system(Quark b², U.S.A). The regional body mineral density measured by DEXA (PRODIGY, U.S.A). For analysis, multiple and canonical correlation analysis were used by SAS(ver9.4). The AT and VO₂max of female Taekwondo player were significantly positive correlation with most body mineral density. The remaining variables(VEmax, RER and HRrest) were non significantly correlation with a almost all body mineral density. However HRrest of female Taekwondo player were negative correlation with all regional body mineral density. In the canonical correlation of between cardiorespiratory function(independent variable) and regional body mineral density(dependent variable) in female Taekwondo player were high canonical coefficient (r=.93). Also BMD of leg in regional body mineral density was most important factor to cardiorespiratory function in female Taekwondo player. The results suggest that high AT and VO₂max may have positive effect for regional body mineral density. So, we suggest that a regular aerobic exercise might prevent of osteoporosis through increase of AT and VO2max.
