 |
|
| Hoping someone out there can help me. My son competes in spring/summer track with a local club. He does the pentathlon. He is fairly short for his age. He's not receiving much in the way of HJ training. Need some tips that will help him to improve his technique and performance. He's not always consistent with what side (left or right) he approaches from and I've also noticed him switch up on the take-off leg (partly due to coaching instruction). I also need tips on helping him to improve his take off and vertical jumping ability. He has shown some potential to be a decent high-jumper, but is not improving as he should. Any tips/advice? Please help! |

| I'll look that up, thanks. Do you recommend plyometric work for HJ? |

High jumping technique is highly dependent on getting the approach right. If you lay out an approach that "works" and use it properly, technique of the takeoff and flight dynamics is easy. If the approach does not "work" then nothing about the takeoff and flight dynamics will work.
I use a computer program that I wrote to generate approaches that "work" based on some basic information that I enter. Approaches can be tailored to the jumper and adjusted as the jumper gets stronger and faster. I will be happy to send you a complementary copy of the program is you can tell me where to email it.

I don't have a direct interest in HJ, but I'm curious what sort of information you enter to generate the proper approach? Height, speed, jumping ability? Are you changing both the length and angle of the approach based on that info?

Hi Dan,
You can enter many different parameters, but I favor the following:
Flight length - how far the jumper travels in the air from takeoff point to landing point.
Flight Angle - The angle that the flight path makes with the bar.
Curve Radius - This is the part of the approach shape that determines how fast the jumper spins in the air about an axis approximately parallel to the bar. It allows you to adjust this spin rate so that all parts of your body can clear the bar by the same amount (efficiently). If this spin rate is too slow, the jumper will drag the bar off with the lower body (the most common problem).
Run Length - The total length of the approach run. The program will keep this length the same no matter what else changes so that your steps will always end up on the takeoff mark.
The output is a series of pairs of measurements that allow you to measure out the approach on the ground.
The program also has a coaching help file to assist with understanding why the approaches it generates work consistently.

Hello highjumpcoach.
Wow, your program sounds great. I'd like to learn more. Although I'm not sure I'd even begin to know how to get those measurements. |

agreed sounds like a nice program - I always went old school in methods with my own little twist on it when coaching high jumpers but I can see how well this type of approach could be very beneficial -

trackmama,
If you can measure the distance from the takeoff point to the landing point and how high the jumper is jumping, I can make a fair guess at the rest. At least it will give you a reasonable approach to work from.

There is a lot of information on my web site about high jumping and approach technique in general, and on how to set up an approach using the software.
