LONG JUMP: HOW DO YOU KNOW IF YOU ARE FAST ENOUGH?

VIDEO CONTENT
Calculating run-up speed and knowing how to get more
Intro: Focus speed over the last 10m
I have had many questions on this subject
17.07sec:
I use the Freelap system and time 11m-1m out from the board
Many authorities time over 11-1m and 5m-1m out.
47sec: Times from my jumpers
Comparison between run-way speed and fly (on track) 10m speed
1.17min: My calculation for the difference between a fly 10 on the track and a fly 10m on the run-up
1.41min Calculating Jump Distance from Speed
It’s useful to calculate speed in metres per second
Info provided on approach speeds for elite jumpers (male and female)
2.23min Horizontal and Vertical Velocity
As they affect take-off
You can’t just focus on horizontal velocity across the take-off…
3.00min: World Athletics Data
Use this data to better understand your jumping
Note divide the final three step speeds by 3 to get an average if you are timing 10m with a Freelap to get a reasonable meaningful comparison.
3.31min: Know your Jumpers or Yourself as a Jumper
Are you/they speed based, eccentrically strong and so on
This will enable you to reasonably well predict distances achievable
4.00min: Using Paul (one of my jumpers) to Showcase How you can Calculate Potential
4.50min: Adding to the Equation
Using 14-15 step Jumps as another Key Determinant
5.09min: Do any Tables Exist for calculating jump distance?
I showcase some “old” German research which correlates 100m speed to jump distance
Please study the tables
5.59min: Summing up and any questions

Good evening John. Thank you for a well concise and presented video piece. When are you going to start selling the Long Jump mats please as I’m still interested in making a purchase

[@ajithamala]

Thanks

Hello! I recently had a prcedure on my knee (November) and really cannot wait to get back to Long and Triple jump. As I cant run or do any plyos or anything, Im really trying to figure out SOMETHING I can do to to catch up at least a little bit. Do you have anything you can reccomend specifically for jumpers?

[@El_Suertero]

If we have Velocity at TO (on plank) + angle at which body of the athlete is departuring from plank ( let's consider the athletes body's Center of Gravity as base point, we can measure angle simply through video recording of jumps) then we can calculate the highest point of trajectory he could potentially achieve and max. Range by using formula R(range)= V^2(2sinø cosø)/g or V^2 sin(2ø)/g. Letter (symbol) ø is for angle at departure from the plank (or TO angle). If simple, without taking in account some aerodynamic forces on body, which form of body placement athlete has in flight, wind, etc. If I remember correctly the formulas from ballistics :). If you have some matematicians within your training groups who know how to calculate that, then they could do it for you or for themselfs and test in practice how close it is to real results "in sand box".

[@Johnshepherdtrackcoach]

Many thanks we looked into this at training today … we need a mathematician though!

Jesus died so that you could go to Heaven. He loves you . He would really like a relationship with you and for you to live for him. I recommend that you read the Bible💙😊

@@Johnshepherdtrackcoach Velocity x Velocity x (sin 2 ø)/g (Acceleration of Gravity) is constant 9.81 m/s
For Example, if we take Velocity 9 m/s at take-off and 30 degrees of Take-off angle (I read recently in one research about technique that give Velocity 8,8 m/s after take-off and angle between 21-30 degrees, so I take 9 m/s for simplicity and I believe it could be achievable in future also or even higher). Then calculations looks like R = 9 x 9 x sin(2 x 30)/9.81 = 81 x sin(60)/9.81 = 81 x 0,866 / 9.81 = 70.146 / 9.81 = 7.15 m
The highest Range of flight will be achieved with angle of 45 degrees which will be 90 degrees for fornula and = 1. Sin of any angles fo more or less than 90 degrees < 1 always.
As athlete fly in some "aerodynamic shape" it also affects rage with wind resistance, drag, etc. So in theory athletes goal is to achieve highest speed possible and as high angle as possible close to 45 degrees but no more plus he can develop some "special flight acrobatics" or "flight shape" or how he could change shapes within flight :) to reduce negative effects of drag, wind resistance, etc. Hope it makes sense. That's idea if you imagine athlete like a bullet, he should shoot himself with highest possible speed at as close to 45 degree angle as possible.
As max speed is limited to about 9,5m/s (which is about 10.5 sec time for 100m sprint) that is impossible for most female athletes to achieve and if you have a male long jumper who could run at such speed, maybe would be better if he will change his specialisation to sprinting or he would work hard on techniques that give him desirable TO angle (may be it's will be completely different from what we use now). And, offcourse, he could think about implementing some revolutionary new behavior (flight acrobatics or body shape or placement in space or couple of shapes on different stages of flight) within flight time.
P.S. It also may be not applicable in full extent, looking for world records for long jumpers (male and female) but would be interesting if you analyse their top speed, angles, shapes and other factors.

[@lancefaulkner2640]

Do you use similar speed testing for triple jumpers as well? Could that provide useful?

[@Johnshepherdtrackcoach]

Yes, the more speed that can be generated the more speed reserve there is as it were. Triple jump and long jump are very similar in terms of run-up speed in that being able to control/use optimum speed for take-off is key. So, the higher that optimum speed, everything else being equal, the further the jump will be. I am unaware of calculations for triple jump distance from 100m time or velocity over the final part of the run-up. Hop length and the phase ratio of the jumper would be influencing variables making it more potentially problematic.

[@jaredstepp7921]

On the German research table, does the {m} meters column on the left correspond to the velocity column to the right of it? It seems like that's how it's set up to me. But I'm confused because my speed 11.55 would correspond better to the meters number to the other side (right) of it - 5.98m. Maybe I'm a speed based jumper and am not maximizing my landing? I'm 41 (masters athlete). It was true of my high school times/jumps also - 10.9 sec and 6.55m.

[@Johnshepherdtrackcoach]

It reads rspeed (right), distance (left). So 10.00 100m gives 8.80m! There is a margin built into the research as I noted in the video - to accommodate landing mechanics and jumper type. It would appear you need to work on better speed to jump transfer and optimising take-off mechanics to enable you to use your speed. I didn’t run that many 100m having a best of 11.0 (200m 21.8) but jumped 7.66/7.89w. So I guess I took more speed directly into the jump. Thanks for the question!
