Usa vaulters…good morning
in 1995 Tim Mack made a commitment and with hard work, financial insecurity but the support of his family and friends, a University that would allow him to continue with their facility and around their program, a coach that stayed with him even though he had a career and family to attend to.
I think his PR was 18-4, I know his 6 step mark was at 53-6 ish … he actually just missed the team in 2000.. he got his run too far out in Sacramento, was over striding and having difficulty getting in. when he finally got it fixed he was down to his last jump and blew through the pole. One jump from making it.
We know the next 4 years and result in 2004 … and a 54-8 six step mark, a13-8 takeoff and 16-4 grip……
I have to say here, and this is actually not the right thread… but if our coaches and athletes are as confused about how speed is created, and continue to think that how tall or short you are has anything to do with speed, as the poster on the other thread that thinks “It has been exceptionally easy to dispute this chart” I know I will not have to worry about him or his vaulters ever making world class or beating me in a meet, or if we continue to “over emphasis” short run vaulting (it’s a game of physics and speed... and fun and yes beautiful movement when done correctly) we will continue to use the “over stride” technique, reach under at the plant technique, force bend the pole technique and the change the pole and patterns to fit out poor technique mentality that failing to generate the correct force to jump “natural” and to the Bubka and Alan model.
It’s simple.. if you don’t have the correct speed for the stride length you will “over stride”, if you over stride you will compound the problem creating a poor plant/takeoff technique. You can’t have a “free” takeoff without the right run.. and with a poor takeoff and a lack of “penetration” you have to “hang on for dear life” force bend the pole to try and make the pit.. and wonder why we cannot do what Bubka did!!!!!!!!!!..

Ps .. by the way everything that the “poster’ from the other thread has brought into that discussion from the “scientific” sources.. agrees with and the chart confirms the science, math and physics of the chart… including “stride length and stride frequency”… “application of force is the key to running faster”
Shelia’s work is good… “Find the athletes optimal stride length and stride frequency.” Is a correct statement.
“Because of Anthropometric difference (height, leg length, body build) you have to decide which component will give you the most bang for your buck.” Is an incorrect statement or I’m miss understanding it. A “stride” or “step” does not create the distance we cover on a ‘stride”.. Oxymoron? Riddle?.. we actually “bound”, leap.. down the track from the force applied at “launch” the “re-positioning of the legs” is just that (well there is some additional force added by action reaction) re-positioning to “hammer the track again to create force to “catapult” the mass (deferential) down the track.
Vince Anderson is a thumbs up… but he actually isn’t the only one with speed charts and the ones I know of are from the same “stance” and science about the creation of speed.
Someone in Jamaican seems to have “charts” because they have definitely figured it out.
Pss.. a last ps.. it may not seem like it but this info that seems to cross over several threads does pertain to “The Next Generation”. If we don’t step away from speed “thoughts’, guesses, from 15, 20, 30 years ago start to get the physics, speed and application of force right we will continue to “be lucky” when that next Gold medalist comes along.
