Variation Of Different Levels Of Physical Activity In Middle-aged Crowd In Motion Respiratory Function Indicators

Objective: by increasing load exercise to test different physical activity level of thedifference between the breathing function index of the middle-aged and the characteristicsof change. In order to establish a function evaluation system to provide the theory basis forbreathing.Significance:This phenomenon is40-59years for the domestic shortage of theelderly population in force activities, through this research, to make people moreclearly understand the impact of their daily life, physical activity levels onrespiratory function, and thus take appropriate exercise to slow the elderlypopulation decline of respiratory function and improve quality of life.Object of study: This study from the six districts under the Jinan City,Shandong Province, were the subjects of recruitment, the subjects in the age rangeof40to59define the middle-aged population, high levels of physical activity andthe low physical activity level group, the30male to female ratio of1:1.Methods: The main methods are:â‘ literature.â‘¡questionnaire: Thesubjects were divided into high levels of physical activity and low physical activitylevel group set.â‘¢experiment: Bruce tablet experiment with MOXUS gasanalyzers measuring respiratory-related indicators: According to Bruce Tabletexperiments increasing load level indicators related breathing subjects tested.â‘£Data analysis: The collected data entry SPSS17.0related data analysis.Results:â‘ entire campaign group VO2high level of physical activity was the"first and then slow down the rapid rise" trend, movement began to rapidly increasewithin two minutes. And oxygen uptake at each time high level of physical activitygroup were higher than the low level of physical activity groupâ‘¡group of highlevel of physical activity during exercise in incremental exercise showed athree-stage process VCO2change: the slow rise of the rapid riseâ†'sharp declinetrends. Low physical activity levels change range somewhat gentle exercise group,a low variation value.â‘¢high level of physical activity group before the campaignbegan1~3min increase was greater. Low physical activity level at the beginning ofthe movement within the group from1~9minutes to render straight up. Groups inthe movement began within1~2minutes worth a small gap over the movement oftime, gradually pulled away. VO2and VCO2compared with the distance betweenthe two groups, two groups of VE distance is relatively small.â‘£both groups VTchanges during exercise include three phases: a rapid increase inâ†'remainedsteady decline rapidly. I.e. the movement to a certain extent, VT was no significantchange is maintained within a small range, the rise or fall with almost coincide⑤two phenomena showing the change process between4~5minutes after the start ofthe motion, two The overall trend of the data no significant difference.Conclusion: The actual survey results show that women high levels ofphysical activitywere more than men, and the types of activities more ways thanmen; the treadmillincremental exercise, the aerobic capacity of the high level ofphysical activity than lowphysical group the ability to set the levelof activity and oxygen uptake and utilization ofoxygen levels were higher thanthe low physical activity group.
