被动吸烟(passive smoking,PS)指不吸烟者每天吸入香烟烟雾时间在15 min以上[1]。世界卫生组织(WHO)指出:烟草使用与日益蔓延全球的死亡和流行病高度相关[2]。在中国被动吸烟率高达53.5%,严重影响国民健康;香烟烟雾中含一定量自由基,能使体内脂质过氧化(LPO)作用加强,血浆及组织过氧化脂质含量增加[3,4]。运动时随着自由基堆积,机体LPO反应亦相应增强[5],故推测PS会减低机体运动能力。近年来,绿茶茶
Passive smoking (PS) refers to non-smokers daily inhalation of cigarette smoke for more than 15 min [1]. The World Health Organization (WHO) pointed out: Tobacco use is highly correlated with the increasingly global deaths and epidemics [2]. In China, the rate of passive smoking is as high as 53.5%, which seriously affects national health. Cigarette smoke contains a certain amount of free radicals, which can enhance the role of lipid peroxidation (LPO) in vivo and increase the content of lipid peroxidation in plasma and tissue [3,4] . With the movement of free radicals accumulation, the body’s LPO response is also increased accordingly [5], it is speculated that PS will reduce the body’s ability to exercise.
