Championship Swimming - How to improve your techique and swim faster
ISBN: 0-07-144730-X
谁仔细看过比赛录像, 世界冠军50米平均得要23-24次划水?
不过，初学、业余和专业运动员对技术的理解和掌握有相当的出入，不知你是否同意？
好多年没看游泳比赛了，但我觉得在标准大池50米自二十三、四下，可能性好象不大。
以后得找机会数数。
国内前些年有个黑龙江的姑娘叫阎明，长距离自由泳横扫过亚洲一段时间。她在400、800自比赛中，好象每50米要42还是43个动作。
自己或找人把你的技术拍下来，然后和你喜欢的运动员的技术（或者说你想要达到目标）做个对比。也可以看看有哪些跟自我本体感觉不太一致的地方，18下的目标，小意思！
这个18下或者20下，是指你可以保持50米的动作还是保持100米（甚至更长距离）？
请教一下：脑袋要整个侧过来吗？我总是会把水灌到耳朵里
（更专业的嘴只出水一半，半含水就可以了）
関健中的関健、成了你就是一条鮫龍。
在身体已经转向一侧的基础上, 轻微转头或无需转头都能吸气.
很惭愧,俺还不会转身.试过两次,都呛了水也就作罢了.游泳断断续续学了几年,有些是上体育课学的,有些是录像上看的.现在左右手各7划可游完25米.下面的算俺的一些体会吧.
1自由泳手臂运动四个阶段.入水:手指碰到水到转体把手伸到最前面过程.抱水:手掌回拉提肘抓水,此过程一般终结于颈部下方.划水:转体手掌加速下划,终结于拇指中关节接触髋骨突出部.空中飞行:不用说了.
2 Timing:一只手开始入水(手碰到水开始算),另一个手开始划水;一手到最前面时,另一手到最后边,这样可使身体滑行距离长.另一种方法描述:划水对应了入水,抱水对应了空中飞行.
3 打腿:以腰带腿,要有用腰把腿甩出去的感觉.
4 手脚配合:俺是二次打腿.用那侧手划的话,用哪侧的腿打水.
5 手臂运动四个阶段用力:除了划水用力外,其他三个都是放松动作.
6 身体流线型保持:压胸来提高臀部;打腿绷紧腰.
7 换气:转体略早于侧头,否则头部会有起伏.如果你身体柔韧性好的话,可使側头和转体同步.
1.先练习口鼻同时出气六秒, 防止翻身时水进鼻子里.
2.练习原地翻身, 双手可以帮助加快翻身. 初学者一次吸气可以连做六个跟头. 习惯了, 头就不再晕了.
3.开始游自由泳,到中间, 划三次水, 翻一个跟头, 然后接着游, 划三次水, 翻一个跟头, 习惯游泳过程中加翻身动作.
4.靠近池边,翻身后脚搭到池边下一尺,脚尖朝上, 蹬出来时肚皮朝上,然后转向侧面.
5.注意出发的角度,不要太浅或太深.加上两次水下划水,初学者应该能在四五米以外开始吸气.

呼吸的位置不理想,每次到了换气的时候都不是那么轻松自然, 总有点费劲,气短, 还得改进.
Blythe Lucero的杰作第16,17招讲了呼吸配合的时机和动作要点:全身转动和压太阳穴.
跟过去比,进步很大: 原来25米拼不过小年轻,现在竟然可以领先他一个半身位,不可能吧. 应按是我有进步而他有退步(今天喝多了?)才能解释.
你比对手先到池边,回过头看,他还在扑腾呢. 等人感觉,只有此时才不着急!
学好自由泳的关键是要伸
手臂要伸，呼吸脑袋也要伸，整个人就是一直往前伸，身体一伸腰就抬起来了。腰一抬起来您就有浪里白条的感觉了。
不过俺一直想不通为什么其他水生哺乳动物一般都用蝶泳的姿势呢
