有氧运动

有氧运动是指人体在氧气充分供应的情况下进行的体育锻炼。即在运动过程中,人体吸入的氧气与需求相等,达到生理上的平衡状态。简单来说,有氧运动是指任何富韵律性的运动,其运动时间较长(约15分钟或以上),运动强度在中等或中上的程度(最大心率之60%至80%)。有氧运动是一种恒常运动,是持续5分钟以上还有余力的运动。

是不是“有氧运动”,衡量的标准是心率。心率保持在150次/分钟的运动量为有氧运动,因为此时血液可以供给心肌足够的氧气; 因此,它的特点是强度低,有节奏,持续时间较长。要求每次锻炼的时间不少于30分钟,每周坚持3到5次。这种锻炼,氧气能充分燃烧(即氧化)体内的糖分,还可消耗体内脂肪,增强和改善心肺功能,预防骨质疏松,调节心理和精神状态,是健身的主要运动方式。所以说,如果体重超标,要想通过运动来达到减肥的目的,常见的有氧运动项目有:步行、快走、慢跑、竞走、滑冰、长距离游泳、骑自行车、打太极拳、跳健身舞、跳绳/做韵律操、球类运动如篮球、足球等等。有氧运动特点是强度低、有节奏、不中断和持续时间长

Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process.[1] Aerobic literally means "relating to, involving, or requiring free oxygen",[2] and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.[3] Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time.[1]

When practiced in this way, examples of cardiovascular/aerobic exercise are medium to long distance running/jogging, swimming, cycling, and walking, according to the first extensive research on aerobic exercise, conducted in the 1960s on over 5,000 U.S
