LHS ... I'm going to ignore PP's comments for now (I often disagree with him

), other than to say that if you're already vaulting this way, we don't need to see your HIGHBAR vids ... we need to see your VAULTING vids!

Interesting!

I buy that ... entirely!

When I think of how far forward my KNEE was, and how far backwards my TRAIL LEG was, I had the same "split" as you demonstrate. The difference is obvious tho ... I wasn't so flexible that I could straighten my lead leg out like you (nor did it ever occur to me to try this), and if I DID stretch it out like you, I suspect that my adductors would tear. However, if you TARGET this technique, and train accordingly, streteching and strengthening your adductors with lots and lots of drills and excercises, and if you warm up properly before jumping, I don't see why mere mortals couldn't do this like you. Females always seem to have better flexibility in "doing the splits", but I see no reason why males couldn't also do this. Many male gymnasts have surprisingly good flexitility.
Quite honestly, when I did my Bryde Bend, I wasn't trying to be innovative at all ... other than raising my trail leg BACKWARDS and UPWARDS to accentuate the Split before the downswing. I was just trying to go down the best technical path that I could figure out at the time, and the only 2 choices that I considered for the lead leg ... based on observation of other elites ... were to either keep it up or to drop it. I chose to keep it up, since I didn't think I had the gut muscles that Nordwig had to drop it and then "lift" it up again. At the time, I didn't consider the possibility of SWINGING it up ... like Hooker, Lukyanenko, Colwick, etc.
LHS, if you're able to SWING your lead leg up (perhaps as the trail leg catches up to it), you might have something here! An alternative to consider is to tuck it in after your split.

Your PR is 15-0? 16 year old Jr., eh? How long have you been expirementing with this? What was your PR prior to that? Please give us a little historical progress report. It sounds like you're very athletic, and have given this a lot of thought ... and a lot of practice. (I haven't watched you other vids yet ... just your first one.)

I see a slight hint of that in his vaults, but its nowhere nearly as extreme as in your vid. I'll download Stevenson's, and look at it in slo-mo. Is his technique what gave you this idea?

Have you considered tucking your LEAD LEG in, whilst keeping your trail leg long (during the upswing)? 5/8 of the way thru your swing would be in your UPSWING, I think. Just after your trail leg passes the chord, right?

Makes sense to me ... if it works! Even if it's not perfect yet, as long as it shows promise and you're not discouraged by any "gotchas", there's no reason for you to NOT continue working on this technique ... based only on what you're saying here. We need to view your vids of full jumps!
LHSVaulterJJR wrote: ...Best of both worlds? or perhaps a complete flaw in the continuous chain? its a toss up. but once i really get it down and get it on film maybe we can decide the positives and negatives. or maybe if like i said you can base it off the way stevenson jumps. ...

One very important point ...
If you can do this WITHOUT PAUSING in that split, then it conforms to the continuous chain theory. If you're pausing in the split, then that's a passive action that will most likely need correcting. Compared to a normal driving lead knee, we could even argue that your technique is MORE ACTIVE.
Think about it ... even tho the normal lead knee is actively driving, the lower leg is passive ... isn't it? It's not adding any extra energy into the "vaulter-pole system"!
Your technique is doing 2 things ... (a) it's an additional ACTIVE action (to the point of reaching your max split); and (b) it gets your trail leg back further (which is also an ACTIVE motion). This is all on the proviso that you IMMEDIATELY swing with the trail leg, and (perhaps) tuck the lead leg in (or swing ... or do SOMETHING with it).

Well, we might get Stevenson trying to accentuate his lead leg drive even more than he already does, but don't expect any other elites to jump on the bandwagon anytime soon, as that would basically be a step backwards for them. This technique is significantly different, so they would have to abandon their current technique to try this. It's probably a risk (loss of time during there career that they might prefer to spend perfecting their current technique) that most won't be willing to take. I don't mean to be a pessimist here ... because you never know ... but the trend has been that once an intermediate vaulter becomes an elite vaulter by becoming successful with a particular model or technique, you rarely see technical changes that are this "drastic".
If you have the athleticism and the determination to succeed with this technique, then YOU can become the new elite that's successful due to this! I think this is the path that Jason Colwick is carving out for himself. Not that anyone should copy his technique ... yet. Same with your technique ... YOU are the pioneer!
I'm interested in seeing your full vault vids for another reason ... I want to see how the other parts of you vault look ... and what model they follow. Can you explain?
LHSVaulterJJR wrote: ... this really does let u carry your speed through a lot more which is probably why you get more drive with it.

I buy that ... I think! It moves your CoM further towards the pit (compared to the other 2 lead knee styles), so that should improve the pole's rotation to vertical. Dropping the lead knee LOWERS the CoM down further, but your technique moves it FORWARDS further ... towards the pit. It's a tossup what's better.
Open questions ...
1. Does this technique contradict or compliment the laws of physics? What are the technical advantages and disadvantages, from a physics perspective?
2. Is anyone aware an any elites that have tried this technique and either (a) used it successfully; or (b) abandoned it after finding it infeasible?
3. Has Toby Stevenson ever discussed this particular aspect of his technique? What's his opinion about it?
