在众多影响运动能力的因素中,不可忽视的一个因素就是维生素。维生素是维持机体生命活动过程所必需的一类微量的低分子有机化合物,虽然不提供能量且人体需要量微少,但对于维持人体健康和运动能力具有重要作用。维生素作为能量代谢的辅助因子,有利于机体吸收能量和体质构成,在细胞内引起酶或激素样的作用,刺激生理机能、代谢和能量的转换过程。当维生素缺乏时,机体的活动能力就会减弱,抵抗力下降,代谢紊乱,运动效率低下。一般情况下,运动员维生素的需要量比普通人群多,这是由于以下几个方面造成的:第一,运动造成胃肠道对维生素吸收功能的下降;第二,汗液、尿液及粪便中排出量增加;第三,体内维生素的周转率加速。所以,对于运动人群应该注意维生素的补充。以下,给大家介绍与运动能力具有密切关系的几种维生素。
Among the many factors that affect athletic ability, one of the factors that can not be ignored is vitamins. Vitamin is a kind of trace low molecular organic compounds necessary to maintain the body’s life activity process. Although it does not provide energy and the human body needs little, it plays an important role in maintaining human health and athletic ability. Vitamin as a cofactor of energy metabolism, is conducive to the body to absorb energy and constitution, causing enzyme or hormone-like effect in the cell to stimulate the physiological function, metabolism and energy conversion process. When vitamin deficiency, the body’s activity will be weakened, decreased immunity, metabolic disorders, exercise inefficiency. Under normal circumstances, athletes need more vitamin than the general population, which is due to the following aspects: First, the movement caused by gastrointestinal absorption of vitamins decreased; second, sweat, urine and excretion Third, the turnover rate of vitamin in the body is accelerated. Therefore, for sports people should pay attention to vitamin supplements. In the following, we will introduce you to several vitamins that have a close relationship with athletic ability.
