Pre-catch pressure and bridge-kick

Post by SA on Sat Jul 08, 2017 8:58 pm

Its the opposite of the TI deep spear, where pressure is on the top of the arm to pivot the legs up.
its used  a lot in competetive swimming, and a shorter scrappier version in openwater swimming.
It is a form of pushing water down at the front, so to counteract some kicking is needed, but it gives a lot of power and some form of relaxation on the downglide for a fraction of a second too.
The guy uses it mainly on the left arm, like in  a loping style, but almost symmertical in this case.
Hope nightcrawler can add some of it in his stroke.

As an ow swimmer i can say that it is not able to be done in ow where water is not stable as in the pool. For my winter race in Feb 2017 5k in cold and choppy water i used towork on high elbow catch with curved torso like this, in the pool i could sustain the 1:18 pace but in the race i could manage only 1:32, because the choppy water distrupted my technque after 200-300m, then i changed my techniqe to shorter and with less pre-catch version during the race and became faster in the rest meters. By the way, th fasters TI guy had finished 1 hour behind me Very Happy So that i once more experinced that in choppy water mid and backend phaees are becoming more important.

I had the same experince 1 month ago in Cunda 2k ow race where i beated national team swimmers In that race after seeing that i couldnt sustain my pace with long stroke i immediately in the few hundred meters of the race changed my stroke to shorter and punchier stroke with less kick and higher cadance i started to pass them one by one and became the 2nd in general ranking with a remarkable pace according to my country's ranking.

he takes 20-22 strokes per 25 m. thats not a long stroke.
The basic technique is used all over the place in open water swimming.
Dont let your feeling overwhelm your rational thinking.

I dont know about really rough water.
Its not simply high elbow. The whole dynamics is different from a backend stroke.
I doubt you can switch from one style to the other just like that. You also have to train a lot on one style to make it work.

In the below video you may see my front end catch with high elbow but not extreme as David Davies, i dont have such flexible elbows and shoulder rotation due to.lack of flexibility:

Comparing an amateur class swimmer with a world cass is not true and is not constructive, serves to no purpose because amateurs dont have such tough genes and hard training sessions.

OK if thats the case then improvement stops there. You cant swim with moves you cant make.
cant you dip/roll the low shoulder deeper while you keep the elbow at the same place/line during extension?
If thats impossible you cant indeed prestretch-load the paddle to body like a lot of elite swimmers do.
Sorry if it comes accros as harsh and demotivating. Its all compared to elites to see it in perspective.

I am totally hooked on improving good front traction and hooking up the paddle to the body, even with avarage shoulder flex (better than avarage now, its getting better and better)

this is from the TI forum:

After more time with the extra shoulder rotation thing I realise its mostly to simply get a good catch combined with good extension.  Its used for getting an internal shoulder rotation, but not by moving the arm, which is keeping a wide  track, but by rotating the shoulder girdle  a bit furher just before locking in on the water. The above water side also makes recovery easier, which can help prevent shoulder problems.
A nice demonstration can be seen at this clip at the 32.....57 sec mark for example.
The roll almost stops when he extends the arm in the water and than accelerates again to the maximal angle which is effectively internal rotation on a stable forearm in the water.

I doubt this is really advantagous for shoulder health, but its certainly effective in getting good traction on the water.
You have to be a bit patient and wait for the roll to start reversing before pulling back out off this internally rotated arm position to avoid shoulder problems, but when thats done it seems to be ok.

Timing:roll has just reversed a split second ago


Its also a matter of getting used to the action, which requires shoulder flexibility, stabilty and strength , depending how far you go with it.
Anyway, I am not having problems with it while trying,and going to make this an automatic movement for the coming year.


Open water technique. Dont hear anything about back end push

After trying a technuque for a couple of years there may be such a situation that i may realize the new technique isnt going further and also pace is not improving, then i need to return and start from the beginning with a new technique or pick your old technique again, spend few years with it then again try another techniques, it has always been like this for me.

I wouldnt change technique this race season. Forget it for now.
If races are over maybe its fun to try other techniques again..

If you have an anchor in front, you can use the trunk to reel that anchor in, just like the trunk action of the climber:

calvin justus
https://www.youtube.com/watch?v=CV7cbM6sEpw(at 3min 13. pretty extreme example of the technique)
Gianottis
https://www.youtube.com/watch?v=NIRXaf3ZPrs ( at 7 min mark)

its a fun way to swim, but takes a lot of core action.Takes time to train it and use it optimally while not bending and hurting streamline too much.

In the above video of calvin justus there is no anchoring, he is just throving the arms around the sides of his body, no hand elbow recovery and anchored high elbow catch, very little rotation... This is the technique that I am currently imitating, in the frontend my hands wasting less time for the catch and mostly focuses on the pull and push phases in order to reach higher stroke cadance(turnover) which is the easiest way to keep the momentum still and save energy and eliminate the pauses at the front.

I am happy with my left arm but my weak right arm is sometimes slipping the water and also sometimes dropping after the catch. You may obviously see it in the below video, SA(smooth arnie) couldnt have realized and commented on my right arm issue yet  Very Happy
https://youtu.be/XIQi6U7FqtA

Once an olympic swimmer in my next lane had lively watched my technique under the water and has told the same. I think this is because of my operated(had an operation  from my shoulder 5 years ago) left arm's being more bulky and lazy, sometimes right(faster) arm is waiting for my left arm to comlete its recovery and while waiting right elbow drops. In order to correct this there is no solution, on e arm drill doesnt help because each arm works better alone than working together Very Happy

Picture when a moving car collides into a parked car. The kinetic energy of the moving car gets transferred into heat, crumpling metal and kinetic energy of the parked car that now starts moving. Swimmers are working in an open system—we cannot isolate the kinetic energy of a rotating body or a recovering arm, as if it were a closed system, because all of the body parts are connected. The motion of one part affects another. Like the cars colliding, the energy of a counter-rotating body or a recovering arm, when timed correctly, can positively impact the propulsive forces of our hands and feet. Further, all the forces of nature, such as gravity and drag, are acting on the system simultaneously. Coupling motions require more work, and if we succeed, we can use them to our benefit by enabling us to swim faster.

Another example of a coupling motion that is a little easier to visualize is the elite long jumper, who keeps moving his legs and rotating his arms in the air, after the force of the takeoff leg has occurred. So long as the effect of the leg force is still in place and the body is still flying through the air, the coupling motions can augment the effect of that propulsive force, resulting in a longer jump. Simpler and more common coupling motions are the arms swinging while walking. The arm swing adds no propulsive force to the gait, but results in a longer stride.

So that as I mentioned before in my other post that there cannot be concept of "symmety" in swimming, because human body is not symmetrical. So obey your DNA dont resist it, dont let the TI company to damage your nature. lol!
