Shinji's 2 beak kick - angle & strength

[z9050807]

When I am doing 2 beak kick, at the moment just before I trigger the kick , I found that :
(1) the angle between my two legs is a lot wider than what Shinji did in his vedio.
(2) I seem to whip my legs harder than what Shinji did in his vedio.

So I try to control my legs, narrow down the angle, and whip it slightly and it came out that my SPL goes up.

I need 2~3 more strokes to get to the other side at 50m pool.

Is there anything wrong for what I have done?

You mean the SPL goes up at same tempo? You loose speed in other words?

yes, at the same tempo.

Hmmm, let me try to fair guess...

By opening your legs wider, or even too wide (note that there's a big difference between wider, and too wide. Terry opens wider compared to Shinji, but not necessarily too wide...), you may be causing a bit of drag resistance (hard to tell without seeing a clip).

But by wanting to mimic Shinji (for example) who may have an ankle flexibility level that's far better than yours (again, just assuming here), your kick becomes less efficient, and therefore now instead of creating drag as a result of opening too wide, you create even more drag as a result of having a lower body that's now too low.

Logically speaking, if you want to aim toward a compact 2bk and don't have a good ankle flexibility, then Balance remains your best way to achieve it.

But scissor kick is a big thing, and if you want yours to be evaluated, we do need a clip, shot from back view.

Please check the vedio as below.

Thanks a lot.

I'm not an expert coach but it seems you are kicking with both legs at once in a scissor kick. Try just kicking with just one leg and make sure it is the leg opposite the spearing arm. Just my 2 cents.

Thanks a lot.

Your kick is indeed a bit wide:

Dear friend,

Unfortunately there is only a Shinji and honestly I don't think he is human, he is half fish

Dear friends,

First, thank you very much for creating this thread. I am really honored to be mentioned, compared, analyzed and discussed. I thank all of you who post comments and read them.

Coach Suzanne and other TI swimmers have commented so many good points, so I just focus on explaining my intention of "Shinji-style flick kick".

The purpose of the kick is not to create propulsion by itself, but make my body rotation more quickly. So it is natural that your SPL goes up with the flick if it is not connected with body rotation.

And since amplitude of the action gets smaller, the angle of body rotation gets smaller. So you can utilize lateral weight shift less. If your normal swim tempo is above 1.4 seconds, it means you may be utilizing lateral weight shift more, and it gets harder to do the flick. Lest body rotation makes the flick easier, and your tempo goes faster.

At my workshop, all participants experience relationship between tempo and body rotation angle. After finding best angle and tempo, we optimize amplitude of the flick and define timing to start it. You need to change the timing when you change the amplitude.

I hope this comment help you understand my style and try it.

Hello Shinji,

it's just too tempting to ask you directly:

- Would you recommend, that TT 1.4s is the best point to start for focusing on the 2bk?
- How can the best combination of tempo and rotation be found if it's impossible to participate your workshops :-( (isn't 45° optimal for all tempos?)
- How can amplitude and optimal start time of the kick be found when swimming with diffent TT-settings?

Regards,
Werner

PS: I'm very sure not being a single one who would like to take part in more than one of your workshops if they where reachable from Germany...
