高原应激与训练的探讨

A STUDY ON ALTITUDE STRESS AND SUITING EXERCISE

１１名世居平原健康男性受试者，于适应性训练前后进入模拟不同海拔高度的低压舱内，进行高原应激观察。结果显示，未经训练人群初入高原时，ＮＥ、Ｅ含量明显升高（Ｐ＜０．０５），目标追踪错误率和数字译码得分与海拔高度呈量一效关系。皮质醇随海拔高度变化不明显（Ｐ＞０．０５），经过３０天适应性训练后各指标明显改善，提示适应性训练能降低高原应激损害。

ltitude stress and is relationships with suiting exercise were studied with 11 volunteersliving in plain,exposed acutely to the altitudes . which were imitated in low pressue capsule.The concentrations of norepinephrine(NE )and epinephrine(E) of volunteers at 3500 and 4500mbefore exercise were increased much more than those of plain (P< 0. 05 ). The pursuit aimingfaults and digit symbol scores were related with the altitude. The altrtude-effect relationshipbecame weaker after the suiting exercise in period of 30 days. It suggested that the suitingexereise could reduce the altitude stress detriment.
