资料5:器材:有用还是垃圾?(呼吸管的使用建议)Swim Tools: Useful or “Contaminants?”
The Active Swim newsletter in my email inbox listed an article heading that caught my eye 5 Tools to Spice Up Your Swims. The promo copy said Ever wonder what swimmers are doing with fins and snorkels? Here’s a breakdown of helpful gadgets and how to incorporate them into your workouts.
Actually I have a pretty good idea what swimmers are doing with them. In many cases they think the ‘recipe for a workout’ is much like that for a cake. To make a cake, mix together cake flour, eggs, baking powder, vegetable oil, and sugar. To make a workout, mix together pull buoy, paddles,kickboard, fins, and ‘bake’ for an hour or two.
Back in 1988, when I first met Bill Boomer, he referred to them as “contaminants.” By that he meant that they impede the swimmers’ ability to develop the all-important sense of how your body and water interact. At the time I regularly used most of them in my own training and had also used them in coaching my teams. Bill got me to re-examine my own beliefs and over time I came to view them as he did. In the last 20 years the only swim tools I’ve used have been Fistgloves (in the late 90s) and a Tempo Trainer (since 2003).
To most swimmers, and coaches, most tools are simply ways to do more work and virtually all of that work is predicated on overloading the muscles and aerobic system. But as contaminants – and there’s no disputing that they are — they rarely do anything positive for neural adaptation. And as regular readers of this blog will know, I’m a strong believer that a well-tuned brain and nervous system are the most critical aspects of swimming well. (The Tempo Trainer is 100% about neural adaptation.)
The article’s author Steve Munatones is recognized as one of the leading voices covering and coaching coach open water swimming, and was an elite open water marathoner himself. At 49 he can still swim a mean set of 200 – a set I never attempted in college. While Steven and I are friends, we also have some spirited-and-principled differences of opinion on training approaches. The usefulness of swim tools is one of them.
I’ll give my view of the 5 tools Steve reviewed in his article, devoting one blog post to each. I’ll also give a highly subjective rating to each tool. My rating system will be
Would I use or recommend this tool?
1. Not a Chance
2.
3. Highly selectively — with the right focus.
4.
5. In a Heartbeat.
My Rating: 3
I actually find an area of agreement with Steve on the snorkel, but would advocate using it in significantly different ways. First, I don’t think it’s helpful to think of turning your head to breathe as an ‘interruption.’ In fact, rhythmic breathing – preferably to both sides — is an essential part of the freestyle stroke. It is however, IMHO, the most exacting skill in all of swimming. When a skill is that important, that challenging, and you need to do it literally every stroke cycle avoiding it as an inconvenience is not a promising improvement strategy.
I’ll quote a bit of Steve’s review first:
Swimmer’s Snorkel
The snorkel is a relatively new tool in the competitive swimmer’s arsenal. It helps both beginner and veteran swimmers focus on stroke improvement while effectively eliminating the interruption of turning your head to breathe. You can relax, breathe easily and maintain proper body alignment as well as focus on the proper hand pathway under the water.
Rather, you need to figure out the weak points in your skill, develop strategies for correcting them and work at them tirelessly until they become strengths.
The skill challenges in freestyle breathing are mainly in two areas (1) keeping the head aligned as you rotate to breathe; and (2) keeping the leading arm and hand engaged in a firm catch position until you begin rotating back from the breath. I.E. When breathing to the left, the right elbow should remain up, the right palm facing back and stroke pressure should be minimal until the left hip begins to descend in the weight shift.
You can improve #1 only by practicing breathing, not avoiding it.
You can improve #2 by practicing with a snorkel, but the opportunity for neural adaptation (i.e. rewiring your nervous system to replace a struggle with a skill) will be minimal if you follow Steve’s set suggestions of 5 x 100 for newbies or 5 x 200 for veterans. Our brains learn fastest when required to process new inputs at high frequency.
Rather I’d suggest a series of 1 x 25 with snorkel, alternating with 1 x 50 without. Breathe to right on one length and left on next, or bilaterally the whole way.
For a series of perhaps 4 x [25 + 50] focus on imprinting one narrowly-targeted skill or awareness on the 25 w/snorkel, then test your ability to maintain that sensation on the 50 without. Continue repeating with one Focal Point until you feel you are no longer improving the targeted sensation.Then introduce a new one.
Here’s a menu of possible Focal Points you could employ with this set. If you use these, do them in the listed order:
1.Keep lead arm on a Wide Track. Align with shoulder; don’t let it cross toward the middle.
2.Feel as if lead arm and hand are ‘cushioned’ or ‘weightless.’ No downward pressure.
3.Keep axilla (armpit) open with elbow above wrist and fingers hanging. (As illustrated below.)
4.Keep hand still for a moment — after extension and before stroking.
器材:有用还是垃圾?(呼吸管的使用建议)
(2010年12月23日)
Email收件箱中一封《5器材让你游泳爽翻》的简讯吸引了我的眼球。这份广告说一直怀疑泳者究竟用手(脚)蹼或呼吸管来做什么?并推荐了一些能用于训练中的“小玩意”。
我对泳者怎样使用器材认识颇深。很多时候他们就像做蛋糕一样来制定训练套餐。做蛋糕时,人们把面粉、鸡蛋、色拉油、糖等混合在一起。在制作训练计划时,他们把浮漂、手(脚)蹼、踢水板、划水板等混合在一起,然后做一个1-2小时的“训练套餐”。
1988年,我第一次见到Bill Boomer时,他指出,这些器材都是“垃圾“。他意指这些器材妨碍了泳者发展与水建立互动的能力。那时我正在训练和教学中大量使用这些器材。Bill令我重新审视我的做法,并最终接受了他的观点。在其后的20年中,我使用过的游泳器材仅包括“拳套”(90年代末期)和节拍器(2003年起)。
(节拍器)
对大多数泳者和教练而言,器材是进行大负荷肌肉和有氧训练的简便甚至唯一的手段。但作为垃圾—这并非贬损它们—他们对神经适应几乎没有任何积极作用。本博客的常客会知道,我深信一个调校良好的大脑和神经系统,才是游泳最重要的方面(节拍器是100%用于神经适应的)。
(邮件中)那篇文章的作者Steve Munatones被认为是开放水域教学的权威之一,而他本人也是一个超长距离游泳的精英份子。我们是朋友,但我们在训练的观点上,有很多原则性的分歧。器材就是分歧之一。
我会一一点评Steve提到的5种器材。我会给每种器材做出主观上的打分。打分系统如下:
问题:我会使用会推荐这个器材吗?
1分:完全不会
2分:
3分:有选择地使用于适用情形
4分:
5分:强烈推荐
先来看看Steve的观点—关于呼吸管
呼吸管是竞技运动员使用的新式武器。它可以帮助初学者或老手专注于划水的改善,而不必转头去呼吸。你可以很轻易地呼吸,从而保持身体直线,并可专注于正确的划水路线。
我的评分:3分
关于呼吸管的使用,在某种程度上我赞同Steve,但主张以不同的方式来使用。首先,我认为“转头呼吸会打断划水”的观点是不恰当的。事实上,有节奏的呼吸—最好是双侧呼吸—是自由泳划水的一个必要组成。而且,如我直言,是所有技术中要求最高的。对一项如此重要而充满挑战性的技术,你需要在每一划中积极对待,把它视为一个麻烦而回避,并非进取之道。
当然,你需要了解你的弱项,想办法改进它们,直到他们成为强项。
自由泳呼吸技术的挑战,主要在两个方面:1)在你转头呼吸时,保持头部与脊柱成一直线;2)保持你的引领手在一个稳固的抓水位置,直到你转回你的头部。换言之,当你在左侧呼吸时,你的右肘部要保持高位,右手掌向后,让划水压力最小(应指尽量避免划水),直到重心切换中左臀开始下降(*这一动作的正确时机,应是左臂移臂动作完成后,进入水面时*译者)
第一,若要改善呼吸,你只能练习它,而不是回避它。
第二,你可以通过使用呼吸管来获得进步,但若你按照Steve建议的那样,采用5×100(生手)或5×200(老手)的训练量,你几乎没有机会建立起神经适应。
我会建议采取1×25呼吸管和1×50无呼吸管(25左侧呼吸+25右侧呼吸,或全程双侧呼吸)的交替练习。
在一个比如说4×(25+50)的系列练习中,在每个25(带呼吸管)中专注于你要习得的技术,在每个50(无呼吸管)中,测试你能否保持住那种感觉。持续重复一个要点,直到你感到你已无法再提高。然后进入下一项。
下面是可以通过这种方式练习的要点。按下面的顺序练习这些要点:
1、保持引领手在宽轨。与肩膀保持一条直线,不要让它穿过身体中线;
2、引领手或引领臂“无重量”或“被支撑”练习。无下压力。
3、保持腋窝“打开”,肘部高于腕部,手指悬挂(如下)
保持引领臂有效前伸
4、有耐心的手—伸展后,划水前。
