2019,五月十六号,by Gary Luo:
After practicing with women's team today, one thing has brought to my attention, which I want to share with everyone in the team. Everyone has different physical power condition, someone is stronger and someone is weaker. During a race, we need to use our physical power in a smart way.  For instance, let's say in starting phase, everyone is required to deliver a power in 100%; during "cruising" (middle phase) 80% power is required; and in the final, using all the power you have. For those strong persons, you should do excately as what they required, but for the weaker persons, you should do your 100% to help the boat accelerating to the cruising speed and then during the "cruising", you can use 70% or even less to keep up you pase and form. In the final phase, everyone should use all the physical power that they have.  Your pase and form (technique) are very crucial during a race. If you do not know how to use your physical power in a smart way in the race, you will be exausted before the finish line. When you are exausted, you will not be able to keep up your pase and your form will be easly twisted too.  Obviously, if you cannot maintain your technique (keeping up your pase and maintaining your form), you will interfere the person behind you. This type of "interference" is just like "wave" that can travel all the way down to the last row of the boat.  Hopefully, everyone can read this message. Thanks. @all people

Your technique (rhythm, keeping your both arms straight, hinge down, looking forward etc.) plays very important roles in two different aspects:
1) to keep the entire team as ONE, which is the most important thing for dragon boat racing.
2) to prevent yourself from injury.  In an intense competition, if you do not do it right, you very likely get injured.
昨天与女队一起练习后,我注意到一个问题。我想与大家分享一下我的看法。每个人的体能不同,有人强壮,有人较弱。在比赛中,我们需要合理地分配我们的体力。比如,我们可以假设把比赛大致分成三个阶段。阶段一,起始阶段;阶段二,巡航阶段;阶段三,冲刺阶段。如果要求我们在起始阶段用100%的力量。那么,在阶段一,每个人都必须100%的用力。因为这是船只提速的阶段,我们需要在最短的时间内,使船达到“巡航”速度。阶段二,如果按常规要求每个人都需要用80%的力量, 那么体力好的人就一定要按要求做到80%,不打折扣。体力较弱的人,为了合理分配体力,可以根据自己的能力,做到70%甚至更少。在最后冲刺阶段(大概是距终点50米左右,此时Caller会提示大家),每个人都必须全力以赴,把你身体中所有的动力全部毫无保留地输出,传递到你的桨叶上。简单地说,巡航阶段是体力较弱的人唯一可以“喘息、打折扣”的时间。因为巡航阶段在三个阶段中最长,由于长时间过度的体力消耗,很容易使得那些体力较弱的人技术动作变形。如果你的技术动作发生变形,就会形成一个干扰源,这个干扰源会像波浪一样一直传递到船尾最后一排。所以合理地分配你的体力,其中的主要原因之一就是保证你的技术动作不走样、不变形。另外,非常重要的一点是保持正确的技术动作也是防止身体受伤的关键。

By 女队队长Maggie:

建议大家都把Kevin的录像download下来好好看看 的确是很不整齐[Awkward] 包括他提到的上面的手一直在船弦外 往下按压的动作 还有中间几排必须和前排保持一致才能把准确的速度和节奏传给后排

by教练Kevin:

So if you download my video and watch it in slow motion you can see a lot of us pressing at different times. Also some top hands are coming into the boat which results in a slanted stroke when you pull. To fix the top hand pressure issue we need to look up and across at the strokes wrists. When they press and pull, you press and pull! It’s a cumulative effect so if someone is not doing it in the middle then the backs will suffer. The backs can not really see the fronts and rely on the middles for

Timing!

Lastly you can see we don’t really pick up the rate on the start. Whenever I call ups the rate stays more or less the same through the last 15 strokes. We need to really get the boat moving and pick up the rate more! But good practice always getting stronger

跟节奏比尽全力更重要 @所有力量大动作快的同学

全队毛毛虫的推进方式优化的好的话也是很有效率的,但是比统一的入水出水节奏难掌握多了,所以还是保持队形的好

2019五月二号 by Gary Luo:

有兩個明顯的問題。一,要抬頭(目視前方)、挺胸、收腹。二,槳手是在弓背,不是在hinge down (頭與上半身保持直線,以腰為軸,就像門上的合頁一樣,上半身整體以腰為軸向下轉動(hinge down)

前面的人动作比较标准。大家可以注意她的左腿与上半身的配合。同时,将出水时,她有转腕的动作。后面的人,除了之前讲的问题外,她的左腿位置不对,没有转身的动作。

正确的做法是(以右侧桨手为例):hinge down 时,左腿伸直、顶住前方船底或前排座位,同时,上半身以右臀为轴,由船外侧向内侧(从右向左)转动,直到船桨入水为止;起身、向后划水时,上半身以右臀为轴,由内向外(从左向右)转动,同时左腿膝盖弯曲。
另外,我注意到我们有一部分桨手把hinge down误解为弯腰(弓背),这是不对的。hinge是门上的合页,hinge down 要求以腰为轴,上身保持直线(挺胸、收腹)整体向下。大家想象一下,你的上半身是合页的一片,腰部以下是合页的另一片。两片合页以腰为轴开(起身)合(hinge down)转动。@all people

总结起来,我们划船的动作有两个轴。一个以外侧臀部(左侧桨手左臀,右侧桨手右臀)为轴的左右(内外)转动;另一个是以腰为轴的hinge down 与起身、划水的动作。希望大家在训练中,细心体会。谢谢!@all

As Kevin said,  improving fitness is very important for dragon boat race.  I guess, through the practice today, everyone can feel improving fitness is the key of dragon boat race.

关于“毛毛虫现象”的分析:
有人说,看了Kevin的录影后,感觉我们船桨的运动轨迹就像一条毛毛虫(看所有人上手的运动),这是什么原因?原因就是我们每个桨手都在跟随自己前一排的桨手的频率,而没有跟随第一排stroker的动作。如果每个人都是看自己前一排的桨手,而不是看自己斜对角(左侧看右侧;右侧看左侧)第一排桨手的动作。(如果你看不到第一排,那么要尽量往前看。要看得更远,抬头是关键),就会产生“滞后”现象。因为,在我们跟随别人做任何动作时,事实上我们的动作总是会比引领者慢一点点。想象一下,如果第一个人是0,第二个人是0.001,第三个是0.002,第四个是0.003,以此来类推。当第一排的桨手的船桨已经举到最高时,船尾最后一排的船桨可能刚刚举到一半的高度(夸张)。这就是当我们观察船桨的顶端(上手的位置)的运动,高低起伏,犹如波浪一般,也像毛毛虫爬行一样。

I’d also like to make this understood as I heard that many of you were sore after yesterday’s practice. This is a good thing. The next day after practice, everyone should be sore. If you are not, you’re not pushing yourself hard enough. Even experience paddlers will still get sore after practice because they continue to push themselves. At this point in time, I know some are new and some have been paddling for longer. For those who have been paddling for a while, your lower back should not be sore .
When you are paddling, you are not using your lower back to move your body. If you have paddled for a while already and your lower back still gets sore, then you have to be more careful and focus on your technique.
For new paddlers, the entirety of your back being sore is common so there’s nothing to worry about. It differs between people but your lower back should stop getting sore after 2-3 months of regular paddling, in my experience. Your butt being sore is fine. Dragon boating, although is doesn’t look like it, requires plenty of lower body strength as well

龙舟比赛中的术语

Call number off  按排数报号 每排都只报自己的号 而且需要和划桨的节奏配合 第一桨往下插水的时候报“one”第二排第二桨的时候报“two”目的是每排左右桨手保持一致 同时全船队员了解自己的位置顺序以及节奏

paddles up 划船练习的起始动作 身体前倾 A型手 桨在水外 离水面一寸

lock-in 划船比赛的起始动作 身体外靠船弦 A型手 桨叶全部埋在水里 号子手会喊 Paddlers ate you ready? Attention go (正式比赛会用喇叭horn 替代Go”大家不需要回答 全副精力注意 一听到Go就开划

Drag the boat 桨叶放入水中 但是桨叶和水平面一个方向 目的是维持船和水面的起伏 在有浪过来的时候维持平衡

Hold the boat 桨放入水中 但是桨叶和水平面垂直方向 目的是停止船的前后移动 保持在一个固定点

————————————————
几个昨天训练中的常见问题 第一 身体往下弯得不够 弯腰不是弯背 不然 后面的队员就会不够空间往下弯动作到位 第二 回桨一定要迅速 不然后排人本能会跟着你慢下来 整队节奏就错了 如果后排紧跟第一排stroker的节奏 那就一定打桨 或者后排心慌容易脱桨 第三 节奏 教练再三强调 起始的时候节奏越来越快 如果因为各种原因没有办法做到强有力的全桨 那么半桨也可以 关键就是节奏一定要对 半桨的意思就是不用拉到后面够长的位置 能拉到多远就多远 要及时回桨跟节奏 这个是关键中的关键 一定要一致

by 北美户外龍舟两支队伍的大领导@闪亮的日子(Jane):
@All
今天是加训。First, I take my hat off to everyone today. 各位队友,教练 @Kevin,caller @junwen , steer @Andrew,@Jerry 辛苦了。 各位队友都是俗务缠身,各自有家庭孩子,周六本来是陪伴家人,送孩子去各种培训班,或者陪自己的父母的时候,仍然赶来加训, 不是为了全队的利益,不是真心喜爱这项运动,是做不到的。 看今天的视频,我只能说感动。九月份刚开始的时候,和现在,我们龙舟队已不可同日而语。 没有各位队友的努力是做不到的。为此,我谢谢各位。

@All
龙舟队是很难的一项运动,恐怕户外运动中,没有比龙舟对团队精神要求更高的了。可是在讲究团队精神的同时,对个人也有很高的要求。这种要求不仅仅体现在划龙舟,即在船上的时间,也体现在陆地上,按时到场训练,warm up, 听从指挥,cool down 并按时退场。这要求每个人的配合和妥协。团队的凝聚力是靠每个人的自律以及对自己队友的尊重建立起来的。 目前我们的有些队员们在训练中没有做到这一点。如果家庭或者工作原因,请说明。大家都会理解的。沟通是双向的。你不说,我也不会知道。

By 义工舵手安得鲁:

一点小感悟:龙舟是集体运动,大家应该放下个人荣誉和情感,更关注集团的荣誉,尊重每位成员。在集体运动中,不管你是大老板,还是运动健康。要和集体合拍,太快太慢都不行。虚心接受别人的建议,没人多贡献一点,我们的力量会更大。祝我们龙舟队取得好成绩!

by 教练Kevin 2 weeks ago:

So a couple of things for both boats aside from top arm straight and hip movement. We need to make sure we recover (air time) faster a lot of us are lagging at the back and not snapping forward at the back of the stroke. Secondly, paddlers are recovering too far away from the boat. You should lift the top arm and snap forward and not go too far out to the side. Essentially it is like a lift  and plant (talking about the padde) lift the paddle then plant it down at the front. Lastly we need more body movement a lot of people are just sitting up right and not using their bodies to drop down onto the blade.

Videos form today are poster below. Please review your positioning throughout the workout Gordon and Howard are good examples of the stroke I am looking for (although Gordon you can get down a bit more by hinging to get deeper water)! Look at how Howard stretches forward and is “big” the whole time (big open frame and set up) and pulling long strokes. Everyone else behind them in the boat is responsible for following that technique and moving the same way
