I believe you are just saying it differently.  However, you are not teaching height when teaching or reinforcing positioning at take-off.  You are teaching postural awareness, as height is a symptom of take-off angle and speed just as length is symptom of take-off angle and speed.

How many since you have been in high school have you heard a coach say to an athlete at a meet these things after telling them they had a less than optimal jump.

“Drive that knee through”
“Get some pop off the board”
“you have to get more height”

I can almost guarantee you 9 times out 10 the next jump will be just as bad if not worse after this type of feedback is given to the athlete as they are likely to scratch or create a really high take-off angle compared to their last jump while sacrificing speed.

While correct positioning is more about acceleration, speed maintenance, stride patterning, and leg stiffness.  You cannot get correct positioning on a consistent basis without these.

yes i have that article…thanks.

FYI. there is 99% of the time a loss of speed at take off for elite long jumpers. I have only ever seen ONE jumper actually accelerate off the board consistantly and i have lots of biomachanics reports from meets, squad trainings ect ect…

btw, research studies are good, but actual data from what jumpers do in meets is much better.

And honestly, this post has got rediculus, that article jumps confirms what i have been saying…i honestly think you are lost as to what you are trying prove and what your not…

Also, if this is now about ex400 not knowing if its harder to get height the faster you run then i suggest you read some very basic books on long jumping. I do not know a single coach or jumper that would say it isnt easier to gget height when you run slow. It is so basic, the slower you run the easier it is a apply great force to the track, when you have such little time to generate the same force needed when you are super fast. You say you were a jumper, are you saying that you struggled to get height from short approach jumps in training but found it easy to get height from a full run? If this was the case, i would have jumped 8.20m already.

i assure you i have said nothing in-correct on this thread….but i doubt ill check it again…it is just silly now…

The path to mastery will have many bumps in the road. Never lose sight of the goal. 8 metres.

Yes, it is just silly now.  All I ever asked for was either theory or evidence to support your assertion that the slower the jumper, the higher the optimum angle of take-off.  I would still like this, but I think we are all weary of this.  BTW, I think you are lucky to have Mike coaching you and he will help you find and hit your optimum take-off angle.

I am very lucky…he’s a great guy and a great coach…we work well together…thanks…

Just some quick numbers i found…from the 2004 birmingham grand prix…

Chris tomlinsons best jump came from his slowest at board speed and that same jump also had his longest final stride…

Dwight Phillips best jump came from his fastest at board speed which also had his second shortest final stride of his series…

This should at least demonstrate the difference of athletes/ optimal angles/ speed at board and its desired effect.

I was at that meet, and i assure you Chris’s jump was his best height of his series, and Dwights was his fastest but very flat indeed.

I want to post a link to Saladino’s 8.73 jump from an interesting angle, it’s actually a “flat” jump. There’s a lot of people getting same lift off the board yet jumping way less than him.
This angle, side view and observer height, shows that he doesn´t get that much of a lift as awaited in such an enormous jump.

The faster the jump the flatter the trajectory will look, but it’s deceiving as the change in his hip height from the ground was huge (at least 30+ inches).

I wouldn’t call that low but it’s definitely not a big booming jump like Powell or Phillips in their hayday. As has been said, speed at takeoff is overwhelmingly the biggest factor influencing the measured distance. But, if a slower jumper wants to jump as far as a faster jumper, they either have to get faster or be able to have a greater takeoff angle; the latter of which is difficult without creating a further discrepancy in speed at takeoff. Thanks for the video. That’s a great angle to take a look at his takeoff. If only the video were a little less shaky.

Yeah, he did get nice height on that jump for sure. His height + his speed + his reactive power + his landing = HUGE!!!

Suspension device: http://www.mmatletismo.com.br/index_files/Page981.htm

You will find it under TREINAMENTOS - M&M ATLETISMO. It is not Saladino though..

Lewis almost certainly has his hands on a 3rd consecutive gold medal…Powell good sprinting speed….oh that is huge!

No problems Nick!

I have been thinking about experimenting with suspension training myself for about a year now.
Interesting…

Oh really!

yeah, we have the stuff now here at school…getting it installed soon and then the study will get started. Expensive stuff but luckily the school is backing me. !
