| 1 ObjectiveTo study the negative effects of the drug will have on human cardiovascular function,improve the effect of movement is inevitable on human cardiovascular function,but the domestic of aerobic exercise intervention on cardiovascular function of drug addicts are lacked.This thesis aims to analyze through new drugs with and without exercise habits of drug addicts in the cardiovascular disease function index data comparison,observe the effect caused by the movement of male drug addicts of new drugs after exercise overall cardiovascular function and motor ability,grasp the trend of relevant indicators of drug addicts during the intervention before and after the cardiovascular function,and through the sedentary group of new drug addicts measured data collation,comparison analysis results,to explore new ways to restore and improve the level of the cardiovascular function of drug addicts and follow-up study Reference resources.2 Methods40 new drug addicts will study,were randomly divided into two groups,one group of 20 drug addicts in physical labor and physical exercise habits set to exercise;the other 20 drug addicts is set to the control group,the 20 subjects were required to keep the diet and rest regular daily.Among all of the subjects were at the age of 30-40 years,drug addicts were selected or injecting drug use for more than a year.Determination of the content of research object including the basis of heart rate(RHR),blood pressure(BP),ankle brachial index(ABI)and brachial ankle pulse wave veloeity(baPWV)reflect cardiovascular function indicators,to assess the overall function of cardiovascular system;motion by 2min incremental power cycling experiment,Power 75W,60/min frequency pedaling,each level of load to maintain 2 min,without a direct level under increasing load,and the subjects in the movement of the heart rate,blood pressure,electrocardiogram and other related indicators of cardiovascular function of synchronous monitoring records,the research object of all synchronous 12 lead ECG measurement,aVR lead voltage and,according to the formula of LVEF=β1aVR+β2age(β1=2.264,β2=0.645),and ejection fraction(EF)and the use of MATLAB software.The measured data were compared and analyzed.3 Results(1)the exercise habits of group and non group exercise test results of mean comparison,results all static indicators,only the left upper limb of diastolic pressure,left ankle brachial index,there is a significant difference between the ejection fraction index,dynamic index only 3,4,5 RPE sports level there is significant difference between(2.)comparison of different drug history between the two groups.Blood pressure,without exercise habits of drug addicts left upper limb mean pressure,left lower limb systolic blood pressure,diastolic blood pressure,diastolic blood pressure of right upper limb with significant difference(p<0.05,p<0.01),the increase of ambulatory blood pressure index with duration of drug use increased.Before the corresponding grade three history of drug addicts systolic blood pressure,diastolic blood pressure through the comparison between the groups,there was significant difference(p<0.05,p<0.01),sport grade 6,no difference between ambulatory blood pressure index(p>0.05);(3)comparison of different drug history between the two groups of peripheral artery index,Each section has history of drug abuse exercise ejection fraction was significantly higher than the group without exercise habits group(p<0.05,p<0.01),a group of bilateral exercise habits of pulse wave velocity No exercise group was significantly lower than that(p<0.05)4 Research conclusions(1)exercise habits improved the partial cardiovascular indexes of the 30-40 year old new drug addicts,but the effect was not obvious,but it also improved their exercise ability to some extent(2)baPWV showed an upward trend with the increase of drug abuse history,and the degree of hardening of the blood vessel increased(3)exercise habit improved the blood pressure and arterial elasticity of limbs of 30-40 year old new drug addicts,and was positively related to the number of drug addicts... |
