| 摘 要： | 目的探讨高压氧对高原移居青年体力作业效率的影响。方法将进驻海拔3 700 m半年的20名健康青年随机分为两组,每组10人。分别采用高压氧前(对照组)和高压氧2次(A组)及5次(B组)后第2天和第8天进行自身对比运动负荷实验。受试者用EGM型踏车功量计做坐位踏车运动。初始负荷功率50W,每3 min递增50W,以60 r/min连续踏车至200 W3 min后终止。用直线回归法计算每位受试者运动心率达170次/min时机体所做的功(PWC170)和运动功率90 W时的心率(HR90W),记录功率200W时的肺通气量及血氧饱和度(SaO2),计算心功能指数。结果两组高压氧组较对照组PWC170、SaO2及心功能指数均增高(P<0.01);HR90W、肺通气量降低(P<0.01),且其效率能保持1周。结论高压氧能明显提高高原移居青年的体力作业效率。

| Abstract: | Objective To explore the effects of hyperbaric oxygen(HBO) on physical work efficiency at high altitude.Methods Twenty youths acclimatized the altitude of 3,700 meters for half a year were randomly assigned into Group A(n=10,HBO for twice) and Group B(n=10,HBO for 5 times).EGM efficiency-bicycle was pedaled(initial load 25W with an increase 50W per 3 minutes to exhaustion) before(control group) and after HBO for 2 and 8 days,and then their heart rate(HR) and arterial oxygen saturation(SaO2) at 200 W were ca... |
