In this video I take a look at some old German research (circa 1980) which looks at various factors that affect the long jump. In doing so I hope that this will aid your understanding of the event.
I have often added more scientific and biomechanical knowledge to my experiential knowledge and self-developed understanding of how to coach the long jump over the years.
Doing this can bolster what you think you already know (!), challenge existing thoughts and give you new ideas and areas to work on.
VIDEO-TIME-LINE
0.00min: Intro
Key focus is 100m time, flight time and landing depth as factors which determine the long jump
1.32: The Research
Key is the influence of speed (100m)
Originates from the Cologne Sports School
Slide: Selected 100m times and projected jump distance
Full table of old research presented (Kangaroo Club Magazine)
Considerations = +3%/- of indicated distance
So, if a jumper does not have sufficient jump power then they will not be able to jump the designated distance (slide).
4.16min: Clarification on the speed jump correlation (slide)
Special take-off power is introduced.
Not every athlete who has speed and power is a good long jumper - there is a technical requirement.
Point to the requirement that 100m speed has to correlate to 30m speed.
5.46min: How to calculate new jump distance from improvements in 100m time (slide)
I suggest final 10m run-up speed is an equal correlation (you will need to understand the relationship and your jumpers).
6.27min: Factors affecting the flight phase (slide)
What happens at take-off regarding the centre of gravity.
Landing depth - looking at achieving an optimise landing ...
7.35min: Explanation of flight
Read in your own time.
7.50min: Flight path (slide)
Once the jumper leaves the ground the centre of gravity of the jumper cannot be altered.
8.22min: Technique
Favour was shown toward the hitch-kick.
Kicking out of the lower swing leg is crucial ...
8.59min: Conditioning
German key thoughts.
Reaction is singled out, as is speed of development of maximal muscular tension within a limited period of time
Low jumps are recommended 9Drop jumps I believe).
I add in fast eccentrics...
10.42min: Summing up
Speed is important but there are other crucial factors - jump height and landing depth. So. we need to focus on ways to improve them.
In the second part of this video I'll bring the research more up to date with some research from Australia, for instance, which looks at take-off angles. And we can see what may have changed.
