刷街中的刹车，下坡和过障碍
4/11/2021 Lincheng Xiu
刷街对轮滑的技术要求相对比较高，在场地上玩的非常好的人，有可能在刷街时出现问题。刷街对轮滑技术的基本要求是刹车，下坡和过障碍，每一项都需要做专项训练，这是我们轮滑班在过去的几年曾经重点训练的内容。
休闲鞋通常用后跟刹车器来刹车，对技术要求相对低，效率非常高，经过训练后，可以在高速上短距离之内杀停。速滑鞋没有刹车器，要用另一只脚的轮子横过来摩擦地面减速，最后停止，称为T刹，对技术要求高，需要较长的时间训练才能够熟练掌握。
刹车技术的重要性是可以想象的，过马路之前没有刹住，冲上马路有可能导致生命危险。从大坡上冲下来不会刹车，有可能失控导致严重摔伤。所有的这些危险在我的初学轮滑过程中几乎都经历过，这也是这几年小朋友轮滑课中，为什么设立刹车，下坡和过障碍等专训练科目，简单的说，都是当年的教训，这些教训如果都写出来，会很长，长到大家没有耐心读完。
下坡是刹车的一个具体应用，这是室外轮滑，刷街的时候，必然要遇到的一个情况，一个1.5公里长下坡，如果你不控制速度的话，到坡底儿有可能达到每小时65公里。一般的休闲鞋在达到这个速度之前，鞋会急剧抖动，失控。通常的做法是在下坡一开始，就要带着刹车，严格控制速度，宁可掉队也不能冒险。
刹车有那么难吗？在高速上你试一下就知道了。最关键的是你的平衡要好，要能在很高的速度上，一只脚上站住，只有这样另外一只脚才能用来刹车。做到这点不是一天的功夫，需要慢工出细活，不断的积累，不断的实践，最后达到一种自然反应的境界。
刷街需要过障碍。基本的要求是能够上下马路牙子，当你后面有车跟着你，已经很不耐烦了，你要有能力跳上人行道。在过马路的时候，你要有能力滑下人行道，而不是被绊倒摔到了马路中间。我们这个城市新修的路都为盲人设置了人行道标志，正好是轮滑障碍，对于初学者有一定的挑战性。过障碍的主要技术是剪刀步，一定要熟练掌握。
过去几年，我们的小朋友轮滑班曾经专门设置了轮滑滑越障碍训练，就是为了让小朋友们安全过马路。在场地上，我们是用木板条来模拟这些障碍，经过大约一两年的训练，小朋友们都能够熟练跨越这些障碍，这也是我们 多次P2P长距离活动，没人受伤的一个重要原因。
如果你的小孩以前没有来上过轮滑班，在报名刷街活动时，请仔细考虑你家小孩在刹车下坡和过障碍的能力。多做实地考察，有针对性的训练，合理的在风险与受益之间平衡，既让小孩参与其中，也将风险降低到最低。如果全程滑不下来，每次只滑一段，没有问题了再滑下一段，步步为营，最后将全程滑下来。
Braking, downhill skating, and overcoming obstacles while skating on the streets

The technical requirements for street skating are relatively high, and people who play very well on the rink may encounter problems when street skating. The basic requirements for roller skating in street skating are braking, downhill control, and obstacle crossing, each of which requires specific training. These have been key training contents for our roller skating class in the past few years.
Leisure skates usually use a heel brake to brake, which requires relatively low technical requirements but is very efficient. After training, you can stop in a short distance at high speeds. Speed skates do not have brakes, and the other foot's wheels are used to friction on the ground to slow down and finally stop, called T-stop. It requires high technical requirements and takes a longer time to master.
The importance of braking skills can be imagined. Failing to stop before crossing the road may lead to life-threatening situations. Not being able to brake while coming down a steep slope may lead to serious injuries due to loss of control. I have experienced almost all of these dangers during my initial roller skating process, which is why we have set up specific training subjects such as braking, downhill control, and obstacle crossing in roller skating classes for kids over the past few years. In short, they are all lessons learned from past experiences. If all of these lessons were written out, they would be too long for everyone to read.
Downhill control is a specific application of braking and is an inevitable situation when street skating outdoors. A 1.5 km long downhill slope can reach speeds of up to 65 km/h at the bottom if the speed is not controlled. General leisure skates will vibrate dramatically and lose control before reaching that speed. The usual practice is to bring brakes at the beginning of the downhill, strictly control speed, and never take risks, even if it means falling behind.
Is braking really that difficult? You'll know if you try it on the highway. The most crucial thing is that your balance has to be good. You have to be able to stand on one foot at high speeds so that you can use the other foot to brake. It takes time and practice to achieve this level of natural reaction.
Street skating involves obstacles. The basic requirement is that you can go up and down curbs. When there's a car following you and getting impatient, you should have the ability to jump onto the sidewalk. When crossing the street, you need to be able to slide down the curb without tripping and falling in the middle of the road. In our city, the new roads are marked with sidewalks for the blind, which are perfect obstacles for inline skating and present a certain level of challenge for beginners. The main technique for overcoming obstacles is the scissor step, which must be mastered proficiently.
In the past few years, we have set up inline skating classes specifically for children, including training for overcoming obstacles, to ensure their safety when crossing the street. On the training ground, we use wooden planks to simulate these obstacles. After about a year or two of training, the children are able to cross these obstacles proficiently. This is also an important reason why none of our participants were injured during multiple long-distance P2P events.
If your child has not attended inline skating classes before, please carefully consider their ability to brake downhill and overcome obstacles when signing them up for street skating activities. Conduct targeted training and practical assessment, balance the risks and benefits, let the children participate, and reduce the risks to the minimum. If you can't skate the entire distance at once, skate one section at a time and gradually build up to the whole distance.
