怎样跑步才能瘦身

1、怎样跑步才能瘦身正确的跑步姿势和方法确实能减肥，可是有些运动减肥失败者却会说，怎么我越跑步越胖呢?看来跑步不能减肥哦。其实，不少运动减肥者的失败往往与其错误的观念和做法有关。误区之一：只要多运动，便可达到减肥目的运动虽能消耗人体内的热量，但仅靠运动减肥效果并不明显，研究表明，即使每天打数小时网球，但只要多喝一两听甜饮料或多吃几块西式糕点，辛辛苦苦的减肥成果便会化为乌有。因此，要想获得持久的减肥效果，除了进行运动外，还应从饮食上进行合理调控。误区之二：空腹运动有损健康人们总担心空腹运动会因体内贮存的糖原大量消耗而发生低血糖反应，如头晕、乏力、心慌等，对健康不利。但美国达拉斯健美运动中心堆帕博士研

2、究认为，饭前12小时(即空腹)进行适度运动，如步行、跳舞、慢跑、骑自行车等，有助于减肥。这是由于此时体内无新的脂肪酸进入脂肪细胞，较易消耗多余的脂肪(特别是产后的脂肪)，减肥效果优于饭后运动。另外，由于运动量适宜，热能消耗较少，体内贮存的能量足够使用，不会影响健康。误区之三：每天坚持30分钟慢跑即可减肥30分钟的慢跑虽可达到有氧锻炼之目的，但减肥成效却甚微，实践证明，只有运动持续时间超过大约40分钟，人体内的脂肪才能被调动起来与糖原一起供能，随着运动时间的延长，脂肪供能的比例可达总消耗量的85%。可见，少于大约40分钟的运动无论强度大小，脂肪消耗均不明显。误区之四：运动减肥有全身或局部的选择人

3、们在一则广告宣传中常听到或看到减腰、减臀、减腹等词句，那么，局部运动是否能减少局部脂肪呢?第一，局部运动消耗的总能量少，易疲劳，且不能持久;第二，脂肪供能是由神经和内泌系统调节控制，但这种调节是全身性的，并非练哪个部位就可以减哪个部位的多余脂肪，而是哪里供血条件好，有利于脂肪消耗，哪里就能减肥。例如，减肥者运动一段时间后，腰围不见小多少，可脸颊却消瘦了，原因即在于此。运动消耗的热量大于摄入的热量，就会导致全身脂肪的减少，而不会只减一个部位，其它部位不变。误区之五：运动强度越大，运动越剧烈，减肥效果越好只有持久的小强度有氧运动才能消耗多余的脂肪，这是由于小强度运动时肌肉主要利用氧化脂肪酸获取能量

4、，因此脂肪消耗得快。运动强度增大，脂肪消耗的比例只占15%。因此，轻松和缓、长时间的低强度运动或心率维持在100?124次/分钟的长时间运动是最有利于减肥。acknowledgements my deepest gratitude goes first and foremost to professor aaa , my supervisor, for her constant encouragement and guidance. she has walked me through all the stages of the writing of this thesis. without h
