罗西腿过弯起什么作用

to gpu leg dungle， so why did rather start doing this？ there's a lot of theories a lot of stories behind this but today i'm going to tell you exactly what this is happening this is the truth behind the leg dungle， so why this is happening well bikes tires and brakes are making constant progress and riders are always trying to find new ways to cope with this progress and improve the performance on the bike the leg dungle was a direct consequence of the increasing performance from the bikes the tires and the brakes we go to a point where sometime because the deceleration the g force was strong in breaking your foot would just slip off the peg and this really happens to all of us what you know was the first one to actually figure out that this could be an advantage， so we started to see him danning his leg in every corner and we could see that really well because one has got really long legs and second they're painted in yellow so everybody was thinking what the hell is going on here so everybody started to pay closer attention to this and then many many writers started to try and do the same and this is why this was nicknamed the doctor's dangle to put this into contest basically motorgp， the carbon brakes and the evolution of the bikes， the brakes and the tires is bringing extra performance， extra braking performance and the braking position is not a comfortable one you got all all the way to the front a massive way transfer onto your arms your feet are placed high up on the pegs and you haven't got much strength basically you just left in position where while basically you're trying to survive because your knees are banned you also have a very little core strength and it's hard to hold yourself back from that massive g force wanted to push you to the front of the bike when all of this is happening when you dungle your inside leg many changes up and i'm going to describe the net the first thing is that you lower your santa gravity so by dungling your leg your foot goes down and it's not only your foot your whole leg your fire as well goes down so this is quite a bit of way that you put more down and lowering the center of gravity increase breaking stability and raking performance you also shifting some weight from the front to the rear basically by downling your leg your fire is going to be straight and more backwards you have a better position on the bike more backwards you'll be able to put more weight onto your bum and more weight onto your outside foot peg， so you'd be a lot more planted and this also increased the braking stability and the braking efficiency there is also a big increase in core strength basically by dropping your leg you're going to feel a lot more planted on the right you're going to feel a lot stronger you have more strength you can use your outside foot a lot more so this will make a big difference because the forces and the physical the physicality of it it's so important you suddenly gonna feel a lot more comfortable stay in there for a few seconds with all those gs into your arms and by dropping your inside leg you also will be able to use your outside innofay onto the tank to use that as a resistance as well， there's also an a road dynamic advantage， so when we're in a straight the rider is hiding you try and be as streamlined as possible to gain some speed in the strait when you're breaking it's the exact opposite you want you want to act like a parachute so riders brake go up in the same time you offer your body with resistance now this has a double effect the first effect is the wind in a sense is going to stop you and the bike so it's going to help you stop you you add air resistance now the circumfing is the forces are massive onto your arms when you break the g forces are are really really strong with motto gp so that wind that is hitting you is actually pushing you back so what it does is it is taking weight off your arms and is helping you cope physically with the demand of motto gp braking zone so pushing your leg outside the frame of the motorcycle is going to add air resistance and also it's adding resistance， but in the right place what it is you're adding resistance low and this is gonna act like an anchor basically like a like an air anchor trying to help you stop and also basically sitting even more by the air resistance sitting the bike more down for breaking this last point is probably a really marginal gain， but in motogp every little marginal gain makes a different and the writers do not do anything by mistakes everything you see on track happening every technique， every little bit of strange thing that you think oh what is it doing that this is all in the quest of finding little temp for nor even temp sun， and and and really fractions of sagans everywhere negative points well， i don't think there is any probably with the boot suppliers like your sponsor is gonna have to supply you a little bit more boots during the season because they tend to get used boots versus tarmac the tarmac will win， but that's about it otherwise it's only advantages does this work on normal bikes or can you do it on your track there well， like i said the games are really really small marginal games so i mean you can try it， but i don't think you're gonna feel a difference unless you're really on the limit so unless you are chasing the lap record on your local track i really i wouldn't bother so i hope you enjoyed this technical video and that you learned something to。

为什么在摩托 gb 的比赛中，罗西过弯要伸条腿出来呢？减速还是耍帅？在比赛中，选手为了能够获得更好的名次，在转弯时都会尽可能晚的减速。而向外伸出一条腿 可以增加空气阻力，帮助选手更快减速到安全的速度，从而成功通过弯道。不光那样把腿伸出去，还可以增加更多的重量，分散到摩托车的后半部分，这样可以在转弯的时候降低重心，提高过弯的成功率。这一动作最早出自于二零零五年的一场比赛， 罗西与他的强敌吉布诺中国冠军时，罗西用这一招将吉布诺挤出了赛道，随后便有人开始效仿。不过也不是所有选手都会这么做，有些车主认为这么做并没有什么实质性作用。上懂车帝搜罗西腿，你会发现罗西自己也说过只是为了户外舒服。你觉得这一招有用吗？欢迎在评论区留下你的看法。

为什么很多 motogp 的赛车手都喜欢在过弯刹车时向外旋伸一条腿？经常看 motogp 的大佬都知道，这就是大名鼎鼎的罗西腿，就连夺过八次世界冠军的马奎斯都经常用罗西腿， 这罗西腿究竟有什么用？为什么车手伸腿后后轮在起跳晃动？为什么会叫罗西腿？因为这个动作最早使用者就是四十六号罗西。很早以前，罗西统治 motogp 的时候，在西班牙站过弯时伸腿轻松 对手反超，而向外伸腿稍加摆动，增加了空气和阻力。其次将更多重量转移到了摩托车的尾部， 从而稳定车身，让车手稳定的过弯。此后纷纷有人效仿，也有 moto g p 车手表示没有任何作用。不过罗西的这个技术发展到现在，很多车手都可以运用自如，因为它确确实实提高了过弯的速度，稳定的过弯，也就是传说中的滑胎过弯。接下来咱们一起来观看 moto g p 大神伸腿的表演吧！

罗西腿究竟有什么魔力？为什么强如马奎斯也会在比赛中经常使出此类绝技？当罗西一招伸腿把吉布诺逼出了赛道后，罗西腿就成了很多摩托车手眼里的香饽饽，很多人开始争相效仿，那么我们就来说说压弯伸腿有什么好处？ 首先第一点，压弯，伸腿绝对不是奔着耍帅去的，因为就压弯而言，不伸腿的林斯绝对算得上压弯中的王者，动作优美，姿势帅气。 但是就压弯伸腿或者不伸腿而言，对于选手真的有影响吗？很多职业选手说过，罗西腿的存在对选手有很多的帮助。第一个就是伸腿对保持平衡有帮助，有了伸腿的帮助，很多人内心会有一份别样的安全感，而且就马奎斯这样的强者，他也经常性的使用伸腿来寻找平衡感。 第二点是因为在赛车比赛中，摩托车的轮胎相对来说比较大，当一个车手驾车压弯时，很对选手会选择伸腿，然后用脚底来接触地面，这样做可以帮助他避免车轮打， 并保持车辆平稳前进。除了保持距离外，伸腿也有助于防止晃动。而且在一定程度上来说，伸腿带来的直接效果是应对车身打滑以后更好的调节自身的平衡。当然，伸腿也是维持姿势的一种方法， 正如我们所知，伸腿的过程会更好地应对空气阻力所带来的影响，毕竟对于职业选手而言，一丝一毫的差距都有可能影响比赛的结果。但是有一点也绝不能排除的就是会有相当一部分人把罗西腿已经融入到了平时的训练中去，在比赛中已经成了一种很自然的肌肉记忆。伸腿或者不伸腿，都不一定是身体所做出的反应，很有可能是下意识的铲出。 很多选手也说伸腿对比赛中没有任何帮助，这样的说法也是有着前车之鉴的，毕竟从不伸腿的林斯也曾将经常伸腿的马奎斯展于车下。那么你觉得摩托车手在比赛压弯中到底应不应该伸腿呢？

在红绿灯路口左转，哈哈哈哈喽，大家好吗？今天给大家分享罗西腿的由来以及作用。首先这项动作源自于场地越野摩托车越野场地相当于公路场地，抓地力比较差，所以越野车手无法在过弯时将身体外挂压低，向前 向下延展，所以车手的身体姿态相较直立。在入弯时和弯中伸出腿，可以帮助车子更好的重心转移，完成转向以及维持车子的平衡来对抗后轮的滑动。这就是大部分摩托 gp 车手在寒假都要去训练越野模特的原因。但是罗西腿大家可以先去尝试一下，在公路赛道当中会不会对你有正向的 帮助？如果你重杀伸腿时，整个核心肌群无法发力，所有的压力都压在手腕、小臂、大臂、肩膀上，而且收回腿的时候总踩不住脚踏。任何技术都是有作用的，不是正向的作用就是副作用，那如果你有这一系列的问题，可能 这项技术就不太适合你。也有很多职业车手是不伸腿的，所以去尝试过后评估一下到底适不适合你是最重要的。好了，多时见，注意安全，拜拜。

哇哦，罗西腿， 哈喽，大家好，这是暴走引擎， 不知道大家发现了没有，视频开头的那几段视频，车手在右往前刹车的时候都有个伸腿的动作。经常看摩托车的老车，你肯定会知道，这就是大名鼎鼎的罗西腿啊，怎么这里大家肯定会很好奇啊，这罗西腿究竟有啥作用啊，现在几乎成为车手过弯的标配技能包了，那么今天我们就来聊一下什么是罗西腿吧，他对过弯有什 什么影响呢？讲到这里，很多摩托 tv 的狂热车迷或者骑车的大神对罗西腿已经比较了解了，你们这部分人可以长按点赞键，一键三连，或者强烈推荐之后把视频关掉了。对于那些对罗西腿还不是很了解的人，也可以一键三连之后再看。 好了开讲。罗西腿，英文名叫的 doutuble， 主要的技术动作是入弯前减速的时候先使用，后刹车的时候同时把腿伸出来闲吊着这个技术动作。讲到 这，肯定很多人好奇啊，为什么叫罗西腿呢？因为这个这些动作最早的使用者正是小飞侠罗西在二零零五年的西班牙赫雷斯， 小飞侠在挂这个弯的时候注意他的左腿明显有个伸腿的动作，然后快速收回，这就是罗细腿的由来啊，如果下次有人问你什么叫罗细腿，记得推荐他来看我这个视频呢。说到罗细腿，还有一个比较地道的叫法，就是罗宾老师在直播间说过的，来看好了，就是这个动作，你知道罗宾老师亲切的叫他为什么吗？是 非常形象的黄狗撒尿啊！这里好汉马丁的动作做到了神似，还有其他什么形象的叫法呢？请留言或者弹幕告诉我吧！缩回罗西腿啊！你们现在知道有个伸腿的动作 什么时候收回呢？首先我们来看一下一个完整的螺丝腿的动作是怎么样完成的。用安全把身体升起来，刹车 同时降档，然后伸腿，等赛车一右弯有倾角的时候就把腿收回来，动作一气呵成，丝般顺滑。不同的射手等他们的技术动作有些许的差异，这个收腿的动作一定是在他们进入弯身的前完成的，那他究竟有什么作用呢？我们参考了 modeled 官网的资料，以及有广运和大神麦克安拜的讲解，我来 总结了一下，主要作用有五点呢。第一就是在车手过左弯的时候，车手的左脚从降档的状态切换到升档 状态的时候，还用脱离脚踏的方式，能让车手过度的更舒服，更自然，更顺滑。看看罗西第一次使用这个动作的时候，注意罗西的左脚明显是在他降完档之后准备转换成生长状态的一种自然的脱落。假设这里肯定会有人说，别扯淡，以前 的人过转弯可没有伸腿这个动作，那就对了，所以他们被我一代撤神小飞侠罗西打的找不到北。肯定还有人会问， 过右弯的时候怎么解释呢？别急啊，接下来的四个作用一一为你解答。我们先讲第二个作用啊，就是在你右弯前中刹的时候，你看阿玛尼把身体伸起来的时候，腿也同时伸出来，这样做的好处就是车手在对抗刹特力的同时，能更好地平衡赛车刮弯就更加顺滑了。 再来看一下罗老板的教科书级别的演示， 罗老板不愧是你，稳得一批。接下来就讲一下第三个作用吧，跟高大上的空气动力鞋有关了。如视频所示，车手在高速行驶的时候，会把身体紧贴着赛车，减少风阻，但是在刹车的时候正好相反，车手会把身体升起来， 增大赛车的迎风的面积，可以让赛车更好的减速啊。而这个时候伸腿的时候的迎风的面积明显比不伸腿的时候更大，所以受到的空气阻力也越大。 所以第三个作用就是可以一定程度上增加刹车的力度，虽然增加的阻力不多，但在速度快的重刹的时候，你看从他们被吹成黄狗撒尿的动作还是有一点力的。来，我们再讲一下第四个作用，就是利用这个伸腿的动作改变赛车整体的重心位置，是重心向转弯的一侧内移， 减少赛车日弯时的倾角，同时可以让车手的上半身在一条直线上面，此车手可以像越野赛车手一样，很好地调整赛车的翻转力气。 高挂弯的极限啊！这种方式特别契合马奎斯这种激烈的驾驶风格，也就是传说中的滑胎过弯。马奎斯把这个用的炉火纯青啊！八戒，世界冠军的小马并非浪得虚名的高手， 肯定会有他的绝招的，一出手便知有没有啊。这种方式唯一的不好就是要拼网纱，拼下他的极限，很容易翻车。不过 罗西腿这个技术发展到现在，很多车手都可以应用自如了，现在的普及化程度非常高，因为他在这时提高了过弯的速度啊。打到第五个原因，也是最后一个原因了，也就是有点咸咸的心理学的原因，因为有 九届世界冠军罗西的背书，车手在过弯的时候因为有世界冠军成功的证明，用了罗西腿的话，整个人都自信了。而心理学中的自信心就是相信自己有能力实现目标的心理倾向，是推动人们进行活动的一种强大的动力， 也是人们完成活动的有力保证，才是一种健康的心理状态，对车手能否做出好成绩是非常有帮助的。好了，就到这了，一项就是罗西腿的五个作用，讲到这里我再次重申了，这种低极限的技术动作只适合在赛道里面玩，在公共道 道路上面骑行千万别模仿啊！还有对老细腿有不懂看法的人，欢迎在评论区留言共同讨论啊！好了，下课想了解更多关于摩托 cb 的硬核知识，请关注暴走引擎法，我们下期再见，拜拜！

猫腿 gp 车手入弯为什么要伸腿？这一技巧的专一名词叫做选腿，也叫罗西腿，日常骑行也能尝试。在猫腿 gp 均速二百的车速中，刹车会带来巨大的重力加速度，这些加速度既会施加在手臂上，也会让脚步非礼脚踏，车子本身也会因为重量的大幅度 前移而变得不稳。骑行时膝盖弯曲，所以无法发挥核心肌肉力量，而腿伸出去就可以改变这一现状。选腿时大腿、小腿都会往下放，能 有效的降低重心，并且大腿伸直重要，会向臀部转移，使重心更靠后。在直线加速时，车手身体全区保证流线型，以便获得更多 的速度，而减速时却是相反，车手要尽可能让身体张开成为降落伞。除了把腿伸出去，车手还会抬高身体，风对身体的冲撞与旋腿，这一打开身体的技巧 都会带走手臂上承受的加速度来应付过猫头 gp 级别的刹车。而这个动作最大的缺点就是费鞋子，如果你想尝试选腿技巧，记得多买几双靴子。

哈喽，大家好吗？接上期视频呢，给大家讲讲这个罗西腿，撸完身腿到底要不要学呢？首先啊，你要知道做这个动作的目的跟好处 是什么，其实在我之前的视频我已经讲过了，像是维持平衡啊，增加刹车风阻啊，或是遮挡后方超车线路啊，还有的车手解释到一条腿伸出来，另一条腿单脚踩脚踏，单腿卡油 香，会更容易使劲啊等等看摩托 gp 的同学们都知道，这是一个主流热门的动作，因为使用的人使用的频率越来越多了，所以咱不否定啊，使用他的车手可能会给他带来好处。重点来了啊，有很多人都是无效的模仿， 起码我们能看到车手都是在入弯有轻脚，车辆比较不稳，比较快的时候再伸腿，而有的人呢，就是一刹车收油就伸腿，而且刹车又早，速度又慢，在入弯前就把 腿给收回去了，那么这个动作就没有效果，这样做只会白白的浪费你的体力啊。所以说啊，这个动作呢，一定要在你有目的有收获的情况下再去尝试做，不要一味的模仿啊，如果你觉得这个动作既消耗你的体力， 又不会提升你的车感与圈速的话，那就不要去做了，因为需要学习与练习的基本功太多了，比如线路啊，刹车，油门，车感，姿势，所以说那只是一个辅助的动作，不用太较真。好了，今天就到这吧，多时间注意安全，拜拜。

快手优。

哈喽，大家好啊，这两天呢，网友朋友问我说这个鬼哥你再讲讲这个刹车伸腿的问题 啊，今天我来总结几条，第一啊，先来说说咱们伸腿的意义在哪？伸腿的意义呢，第一是对抗这个音车速啊 的增加，还有就是刹车科技进步，越来刹车越重而带来的这种负载，然后去做一种抵消啊，靠重心也好，靠这种身体的协调度也好，来做一种抵消。另一种呢，就是重心的偏移下放，因为我们通过这个开腿伸腿， 包括把我们的重心下移啊，包括后移啊，都是一种重心的偏移。第三呢，就是说多少因为你打开腿会带来一点一点的风阻效果，那么真正这个动作呢，它带来的优点和缺点有哪些呢？首先来说优点啊啊，它能够这个减少你的人在刹车时 后的前冲力的这个整个的负载，然后呢，多少通过重心的偏移啊，让这个车身更加的稳定。那第三呢，就是说啊，我通过这个风阻多少呢，可以减少一下这个刹车的距离， 这是他的优点呢，缺点呢，第一呢，真的就是费鞋啊，经常你会磨到鞋底。第二呢，就是说你在伸腿以后，你势必还要收腿，那么减少了你下身的速度啊， 那这个时候你会发现，在所有的连续过关的时候，很少大家会运用到这个技巧，那么下面呢，就有请专业的车手用最专业的东西给大家来讲解一下，详细的看一下啊，看完了以后你会明白，其实这些技巧真的 没有必要在生活中去拿来装逼。 there's a lot of

在二零零零年赛季开始前，杜瀚因为受伤而不得不隐退，本田场队的王牌车手瓦伦蒂诺罗西取而代之，成为了全世界瞩目的焦点。罗西呢，是一个从一九九六年就开始参加世界锦标赛的传奇车手，也是经历了每一个姿势变化的车手，从最开始和车子保持一致的姿势，慢慢变成现在的探身魔肘的姿势。可以说，看罗 罗西个人过弯姿势的转变，就能了解世界锦标赛过弯姿势的发展，并且罗西还从中演化出了自己特有的入弯的姿势，甚至现在很多车手纷纷效仿，这就是罗西的独门绝技，伸腿入弯，这一姿势也成为罗西的标志之一。红牛的 官网是这样介绍罗西的，在拥有科技进步的适应能力和卓越的赛车技巧下，结合了过去所有的脐橙姿势，罗西能够轻松运用抓力过弯与侧滑斜挂过弯两种技巧。

呼呼，丹尼普都起来了，这边一个翻身呢，热天狗跟前面的马王一样啊，罗西腿偏偏那线过到罗伦左。那么问题来了，罗西腿真的这么屌吗？洛伦左可能还不用罗西腿啊，为何现在的这种基本上都用了？这个问题我以前的视频已经讲过了，但是那只是 国外大神的分析结果，可能还有人不相信的。这一次我们就来听一下，摩托级别的车手，他们为什么用螺丝腿？哈哈哈，马王你笑什么？就你用的最骚了，是要致敬偶像吗？算了，还是问狗王吧。 in my cases for a balance ability to stop bed。 好了，听到了没有？没有那么神乎其神了，就是为了平衡稳定以及更好的刹车，其他的作用都是次要的。好了，知道了没有？如果再有人问你，他们开车在开车了，为何伸腿呢？现在知道怎么回答了吧？不是为了耍帅，更不是为了党员了，就是为了重杀的时候平衡身体，让赛车更稳定以及更好的刹车。 来，如果他不相信的话，那就来打看我这个视频喽，应该没有人比摩托军的车手更懂螺丝腿了吧，如果有的话，那就小心了，小心被忽悠了。当然了，对这个伸腿有不同的看法的话，也可以在评论区提出，先这样了，拜拜。

哈喽，大家好吗？上一期我发了一个关于伸腿的视频，今天我给大家分享一下我个人对伸腿的陷阱与我的使用心得。第一，我认为最大的作用就是能在重刹时车辆后轮抬起发生剧烈晃动的时候，更好的维持平衡与稳定车辆。 第二，在你刹车减速的过程中，身体直立，腿部向外伸，这样会增加更大的风阻而提高你刹车的效率。如果你尝试过后呢，可能会发现你的刹车点可以更晚更靠后了。 第三，可以相对的阻拦后方车辆内线超车的线路与机会。不过这一作用大多体现在顶级的摩托车赛事当中，因为他们在前后超车的时候，两车相距非常的近。 好了，今天就说到这里，希望大家可以多实践得出自己的结论，注意安全，拜拜。

专业车手入弯前都喜欢伸一条腿，这么做有啥好处？第一个就是增大风阻，和入弯前直立上半身的作用是一样的，刹车阶段呢，风阻越大，刹车距离越短。第二个好处就是保持平衡啊，和走钢丝拿个棍是一个道理。 我玩了三年赛道，发现伸腿确实有好处，但不是刚才说的那两个。第一个作用就是防止后面车手插进来，比如入弯路线大了，你伸腿他超你的路线没了。第二个作用呢，就是帅，风阻大小我这个水平是骑不出来，但是拍照还是很帅的。这个动作最早是罗西在用，所以叫罗西腿，他第一次用就把其他车手挤出去了。
