前言 本研究的目的是比较下体负压(LBNP)时男性与女性(年龄45岁～65岁)盆腔和腿部的循环改变和血容量的转移。方法 17名女性(平均年龄56岁)和15名男性(平均年龄为55岁)暴露于—50mmHg(1mmHg=0.133kPa)LBNP 15 min。采用Beckman(BK-100)阻抗体积描记仪测量每次LBNP试验时的每位受试者腿和盆腔血流和淤滞情况。结果在—50mmHgLBNP实验末,男性和女性在腿部和
Preface The purpose of this study was to compare pelvic and leg circulation changes and blood volume transfer between men and women (aged 45-65 years) at lower body negative pressure (LBNP). Methods Seventeen women (mean age 56 years) and 15 males (mean age 55 years) were exposed to LBNP at -50 mmHg (1 mmHg = 0.133 kPa) for 15 min. The Beckman (BK-100) impedance plethysmograph was used to measure the leg and pelvic blood flow and stasis in each LBNP test. Results At the end of the -50 mmHgLBNP experiment, both males and females were in the legs and
