你肯定知道体育运动是有益于身体健康的。但体育运动为什么有益于身体健康呢?你可能并不确切地了解。现在,豪斯顿(Houston)的一组科学家们已经详细地指出了一个生物化学机理,这个机理能够解答上面的问题。根据贝鲁医学院约瑟夫·帕茨奇的说法,象慢跑一类的健身疗法提高了一种叫做高浓度脂肪蛋白质(HDL_2)的化学物质的血量标准。

Now, a group of scientists in Houston have pointed out in detail a biochemical mechanism that can answer the above questions. According to Joseph Pattski at Beirut School of Medicine, fitness classes like jogging raise the blood standard for a chemical called high-density lipoprotein (HDL-2).
