运动:它能为你做什么?
佚名
各种不同年龄的美国人都在跑步、跳跃和举重,以保持身体健康。很多人相信,运动对身心有好处。他们说,运动有助于他们减轻体重,变得更有吸引力,或年纪大时仍保持原有的体形。还有些生活节奏非常紧张的人说,运动能帮助他们放松。这些人认为,运动能帮助他们避免由紧张引起的多种健康问题——例如心脏病。这些信念中有些是幻想:不可能或不真实的东西。其他的信念则是事实:真实的东西,因为人们在研究中已经证实了它们。
关于运动的事实是什么呢?仅仅通过运动你就真的能够改变体形?如果进行锻炼是否任何女人都能看上去像简?方达那样身段优美?如果经常举重是否任何男人都能像阿诺德?施瓦辛格那样肌肉发达?事实上,答案是不,并非如此。在你出生前,遗传性就决定了你的脂肪细胞数和你的肌肉线条(你肌肉的显露程度),所以,你的身体通过运动能改变多少是有一个限度的。然而,如果你烧掉(消耗掉)的卡路里超过你摄入的卡路里,你的确能减轻体重。运动与节食相结合能有所帮助,但你大概不会看上去像方达女士那样身段优美,除非你在开始运动前已经身材优美。同样地,你的确能增强并扩大你的肌肉;这可以改进你的整体外观,但它大概不会使你看上去像施瓦辛格那样肌肉发达,除非你一生下来就有他那种肌肉线条。 通过运动来减少压力又怎么样呢?实际上,研究已经表明,做有氧运动(加快心率的运动)能促使脑释放内啡肽,这是身体内的一种减轻痛苦、使身体放松的化学物质。然而,不能保证运动会防止心脏病发作或中风,特别是如果你的家庭成员中有人患过这些疾病。但如果你运动,饮食得当,不吸烟,有一个从容、积极的态度,你就会减少患上与紧张有关的疾病的可能性。
