Cardiovascular Risk Factors Assessment Of Middle Urban With Different Physical Activity Levels

Objective：Object：The object of this research is to investigate the cardiovascularrisk of Jinan urban middle-aged with different physical activity levels，evaluating thecardiovascular risk of those middle-aged and predicting the potential relationshipbetween their PA levels and cardiovascular risk．Mean：Assessment of ji’nan city middle aged physical activity level,theunderstanding of the realationship between different levels of physical activity andcardiovascucal risk,explore the physical activity levels,provides the reference for theevaluation and research of future cardiovascular.Method：The sports and health questionnaire was adopted to jinan citymiddle-aged physical activity energy expenditure situation investigation,choose theeligible subjects，it shall, in accordance with the high level of physical activity canbe divided into physical activity level, low level of physical activity：and trainedresearchers measured their height，weight，waist circumference，fasting bloodglucose，blood lipids，including triglyceride，total cholesterol，high-density lipoproteincholesterol，low-density lipoprotein cholesterol，blood pressure，pulse wave velocity，ankle brachial index and some other cardiovascular risk factors．Then the two groupsof women would participate exercise tests，which were conducted using an electronic，rate-independent cycle ergometer．Cardiorespiratory fitness was measured directly byrecording respiratory gas exchange．Electrocardiograms，heart rates，blood pressure，rating of perceived exertion，were recorded during the test．Results：The results showed that there were significant differences in the totalenergy expenditure of PA，the total sitting time and the ratios of job related physicalactivity，transportation physical activity and household physical activity betweendifferent PA groups；and there was a significant correlation between total sitting timeand the fatness．Significant differences were also found in FBG，PWV and ratios ofhigh cardiovascular risk population between different PA groups．Conclusion：The physical activity levels of Jinan urban middle-aged were at therelative low level；Level of physical activity and obesity are important factors affecting cardiovascular risk. The high level of physical activity on cardiovascularrisk is relatively small．There was a risk, exercise in the elderly can be quiet when thephysiological and biochemical index prediction. One is myocardial ischemia, andsecond, with the increase of sports load drop in blood pressure...
