为什么经常进行体育锻炼能增强体质、防治疾病、益寿延年? 近来,美国医学家约瑟·帕斯茨克揭开了这个谜。他发现在人体内存在一种高密度脂蛋白粒子,这种粒子有主动把血管壁上的脂肪和胆固醇清除掉的作用。并把它命名为HDL_2粒子。不过平时体内产生出来的HDL_2粒子比较少,远不能与脂肪和胆固醇相匹敌,从而沉积物把血管堵塞,影响正常体内供血供氧,加重心脏负担。体育锻炼,能使体内的HDL_2增加,并 Why regular physical exercise can enhance physical fitness, disease prevention, longevity? Recently, the US medical scientist Joseph Pascark opened the mystery. He found that there is a high-density lipoprotein particles in the body, the particles have the initiative to remove the blood vessels on the wall of fat and cholesterol out role. And name it HDL_2 Particle. However, usually generated in vivo HDL_2 particles less, far from fat and cholesterol rival, so that the sediment vascular blockage, affecting the normal blood supply to the body, increasing the burden on the heart. Physical exercise, can increase the body’s HDL_2, and
