某单位在部队进行次极量踏车运动(简称“踏车”)试验时,二例飞行员出现严重反常反应,现报道如下引以注意。 试验方法;在Dynavit Meditronic功率足踏车(西德产)上进行。初始负荷50W,以50W/min递增至最大心率(190—年龄),停止踏车观察5min,记录心电、心音、心导纳图,每分钟测血压一次。 试验终止指标:(1)达到最大心率,(2)心率、血压不随负荷量增加而增加,或降低;(3)连续出现三次异常心律;(4)疲劳不能坚持;(5)其他身体不适。凡符合一项即停止踏车。
When a unit undertook a sub-maximal cycling exercise (referred to as “treadmill”) test, two pilots experienced serious abnormal reactions and are reported as follows. Test method; on Dynavit Meditronic power cycle (West Germany). The initial load of 50W, 50W / min increased to the maximum heart rate (190 - age), stop treadmill observation 5min, record ECG, heart sound, cardiac admittance map, measured blood pressure every minute. End of the test indicators: (1) to achieve the maximum heart rate, (2) heart rate, blood pressure does not increase with the increase in load, or decrease; (3) three consecutive abnormal heart rhythm; (4) fatigue can not adhere to (5) other physical discomfort. Where meet one is to stop treadmill.
