The position of the feet is not the cause of the lowering of cg, it is a result of a slightly longer penultimate stride (next to last stride) and the slight shortening of the last stride (takeoff stride). The longer penultimate stride slightly lowers the CG and the slight shortening of the last stri...

To ADTF Academy; Well, seeing as how we have no examples of great sprinters running without gravitational pull, why don't we look at the great sprinters on earth. At top speed, all sprinters apply force straight down. There is now clawing action. It appears that the action is down and back however b...

THE APPROACH IN THE LONG JUMP, TRIPLE JUMP AND POLE VAULT THE TWO HORIZONTAL JUMPING EVENTS AND THE POLE VAULT SHARE MUCH IN APPROACH MECHANICS. THE APPROACH ALLOWS THE ATHLETE TO DEVELOP SPEED, TEMPO AND PROPER BODY POSITION TO ACHIEVE AN EFFICIENT TAKE OFF. AT ALL TIMES, THE ATHLETE MUST STRIVE TO...

UNDERSTANDING MECHANICS OF JUMPING: • PENULTIMATE STRIDE IS LONGER THAN PREVIOUS STRIDE • FINAL STRIDE (TAKEOFF) IS SHORTER THAN PENULTIMATE STRIDE • FOR MORE ACUTE TAKOFF ANGLE = LONGEST + SHORTEST (HIGH JUMP) • T.J. AND P.V. = LOWEST ANGLE OF ATTACK • PARABOLA IS SET ...

THERE HAVE BEEN MANY GREAT, BIG, FAST, VAULTERS...THERE HAVE BEEN MANY GREAT, SMALL, FAST VAULTERS.....THERE HAS NEVER BEEN A GREAT SLOW VAULTER: SO: SPEED AT TAKEOFF: WORLD CLASS FEMALE VAULTERS 9m > 4m 7.5 m/s to 8.5 m/s WORLD CLASS MALE VAULTERS 10m > 5m 9 m/s to 10 m/s RESEARCH SHOWS THAT AN INC...

Ask this question. If your top hand is at 15' and your bottom hand is at 13', where do you efficiently apply force to the pole? It is much more efficient to apply force from the top hand IF the plant is high (Straight Top Arm). ROLE OF THE LEFT ARM (for Right Handed Vaulters) 1. DO NOT COLLAPSE 2. D...

The left arm straightens because the pole bends. The pole does not bend because of a straight left arm!!!!! If your top hand is at 15' and your bottom hand at 13', where is it most efficient to apply force???? From the top hand, of course. The bottom arm/hand is along to guide the pole, act as a ful...

Let's say your vaulter should be at 10 feet for the takeoff point but always reaches to be at 9 feet. She is compfortable there....have her agree on that. Once she is confident she can alway take off at nine feet, simply go to a bit lighter pole and move her hand grip DOWN so she will be in the corr...

This response is not met to be confrontational, simply informational. To simply describe what one thinks is going on in human movement is really not a great service to the field of Biomechanics. Biomechanics is the key here. Physics does not change. Athletes might look different, however if they are...
