本文通过30例冬泳者进行下水前、下水后即刻的心血管系统多参数自身对照测试,发现初游组比常游组变化显著,初游组EMT下水后即刻为下水前的1.2倍,Q—Z为1.9倍,PEP为3.1倍,ICT为2.6倍,LVET为1.8倍,PEP/LVET为1.7倍,ICT/LVET为1.5倍,PWTT为4.6倍,SET相应缩短,反映舒张功能的指标也延长,RFT为2.2倍,IRT为3.6倍,EDT为2.9倍,AST为2.1倍。等容指数为1.8倍,a/H由16％延长到43％,a/D由42％延长到102％,SFT也相应缩短,反应泵血功能的参数均减少,SV为下水前的41.5％,CO为47.8％,EF为59.8％,IH/TH却增高为2.58倍,外周阻力TPR,初游组惊人地剧增,为下水前的123.1倍(174.9—21538.4)提示冬泳对初游者的心血管系统收缩、舒张、泵血功能多参数是损伤性活动,对常游者损伤不明显,分析了产生的部分机制。
In this paper, 30 cases of winter swimmer before and after launching the cardiovascular system multi-parameter self-control test and found that the initial group than normal group changes significantly, the initial group EMT immediately after the water was 1.2 times before the water, Q- Z was 1.9, PEP 3.1, ICT 2.6, LVET 1.8, PEP / LVET 1.7, ICT / LVET 1.5, PWTT 4.6, SET corresponding shortening, reflecting the diastolic function of the indicators also extended , 2.2 times for RFT, 3.6 times for IRT, 2.9 times for EDT, and 2.1 times for AST. The isoeuteria index is 1.8 times, a / H is prolonged from 16% to 43%, a / D is prolonged from 42% to 102%, SFT is shortened correspondingly, , CO was 47.8%, EF was 59.8%, IH / TH was increased to 2.58 times, peripheral resistance TPR, anaphylactic surge in the initial group, 123.1 times before the release of water (174.9-21538.4) Cardiovascular system systolic, diastolic, pump blood function is a multi-parameter injury activity, the damage is not obvious to tourists, analysis of some of the mechanism.
