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。也就是说,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。体重超标,要想通过运动来达到减肥的目的,有氧运动时不错的选择。
无氧运动,是指肌肉在“缺氧”的状态下高速剧烈运动。由于速度过快和爆发力过猛,人体内的糖分来不及经过氧气分解,而不得不依靠“无氧供能”。这是一种锻炼肌肉让身体变得更强壮的运动方式。
有氧运动最有利于减肥的原因
1.加速新陈代谢
有氧运动是指在有氧代谢状态下做运动,长时间进行运动(耐力运动),使得心(血液循环系统)、肺(呼吸系统)得到充分的有效刺激,提高心、肺功能,从而让全身各组织、器官得到良好的氧气和营养供应,提高新陈代谢,加速消化,消耗热量。
2.运动会使得人体的肾上腺素分泌增
一般情况下,运动会使得人体的肾上腺素分泌增加,从而促进脂肪的燃烧:短期运动产生疲劳感时,肝脏、脂肪组织的脂肪酶、葡萄糖都会被激活,肌肉糖原分解,肾上激素加快心率,加速血液的流通,放松鼻腔、肠胃血管等,加速排毒,加速脂肪燃烧释放热量。
3.降脂
北医三院运动医学研究所陈吉棣教授和她的研究生们,利用已处于高血脂水平的小鼠进行实验。他们让这些高血脂小鼠每天进行有氧运动(让小鼠游泳、跑步)。6到8周后发现,这些小鼠的血脂水平有了显著的降低,它们动脉粥样硬化斑块的形成也得到了明显抑制。
4.有氧运动可增加人体内“好”胆固醇
经常进行有氧运动可增加人体内“好”胆固醇———高密度脂蛋白的含量。人体中的高密度脂蛋白,能将血管中的血脂运到肝脏中处理掉,俗称“好”胆固醇。研究人员发现,从事有氧运动的人平均每0.1升血液里的高密度脂蛋白增加了2.53毫克;能够使高密度脂蛋白发生量变的最少运动量是每周2个小时,或相当于能够消耗900卡路里热量的运动量;对较胖的人来说,有氧运动增加其“好”胆固醇的效果尤为明显。
Aerobic exercise is a sufficient supply of oxygen in the body under the condition of physical exercise. That is to say, in the process of movement, the body of oxygen http://www.wxgs7.com/post/248.html inhalation and the demand is equal, achieve thephysiological state of balance. Weight exceed the standard, to the movement to achieve the purpose of weight, aerobic exercise is a good choice.
Anaerobic exercise, refers to the muscles in the state of "hypoxia" high speed motion. Due to excessive speed and explosive force too, the body of sugar to wait afterdecomposition of oxygen, and had to rely on "anaerobic energy supply". This is a kind of muscles, let the body become more strong motion.
Aerobic www.onhaixi.com exercise is most conducive to weight loss reasons
1, accelerate the new supersedes the old.
Aerobic exercise is the exercise in aerobic condition, long time exercise (endurance exercise), makes the heart(blood circulation), lung (respiratory) were fully effective to stimulate, improve heart and lung function, so thateach organization, and organs of the human body have a good supply of oxygen and nutrients, improve the new supersedes the old., accelerate the digestion, calorie consumption.
2 games can make human body secretion of adrenaline.
Generally, exercise will make human increased secretion of adrenaline, so as to promote www.wgpibao.com fat burning: short termmovement resulting fatigue, liver, adipose tissue lipase,glucose is activated, muscle glycogenolysis, adrenalineaccelerates heart rate, accelerate the blood circulation,relax the nasal fluid, gastrointestinal blood vessels,accelerate detoxification, accelerate fat burning heat release.
3 fat
Chen Jidi No.3 Hospital of Beijing University Research Institute of Sports Medicine professor and her graduate students, experiments using in high lipid levels in mice.They let the hyperlipemia mice daily aerobic exercise (let the mice swimming, running). 6 to 8 weeks after the discovery, lipid levels in these mice had significantly reduced, the formation of their atherosclerosis has also been www.pibaowg.com significantly inhibited.
The 4 aerobic exercise can increase the human body"good" cholesterol
Regular aerobic exercise can increase the human body"good" cholesterol -- high density lipoprotein. High density lipoprotein cholesterol in the body, the blood vessels in the liver to dispose, commonly known as the "good" cholesterol. The researchers found that, aerobic exercisepeople on average every 0.1 liters of blood high density lipoprotein increased by 2.53 mg; the least amount of exercise can www.jiachengfoods.com make the high density lipoprotein change is2 hours a week, or the equivalent of can consume 900 calories exercise; the fat people, there is aerobic exerciseincreases the "good" cholesterol effect is obvious.
