Great video Goran! Wish it was available 30 years ago when i was a high jumper. For those who are wondering about centrifugal force and physics laws around circular motions, here is the definition: Centripetal force is defined as, “The component of force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation,” while centrifugal force is defined as, “The apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body”
I second that!! I was a 7' jumper (only 5'9" tall) and could have been much more. I had a great graduate-assistant coach, but he left after my sophomore year so I was on my own.
When I jumped, my curve was not a constant radius. It was actually a decreasing radius as I neared the bar. I found this to be easier to allow for the long-long-short final three steps. The video ends just as it begins to describe the torque and stress endured by the ankles accelerate through the arc. I would compare these stressful loads to that experienced by a rollercoaster looping through a perfect circle. Coaster engineers discovered that there is far less stress on both the track and the riders if the loop-the-loop were tear=dropped shaped instead instead of perfectly circular. Coincidentally, this is the same discovery I made on my approach. If you cut the rollercoaster loop in half vertically, then you have a general shape of the arc of the curve I would run on my approach. A teardrop shape is an arc with decreasing radius.
Pablo Cid there’s no such thing as centrifugal force sorry. I was liking this video until I heard it and that’s when I realized this wasn’t scientific, it’s folklore.
You don't really need to know the math. Just need to understand the concepts and practice. You want to go at the bar with as much speed as your body can take. You need to build up to that point though, to prevent injury. Higher horizontal speed + a tighter angle of approach = a higher vertical jump. I prefer a wider approach at a higher speed because the angle of my ankle at takeoff is less, which is less strenuous on my ankle.
if you were to go around a circular turn and suddenly hit a patch of ice, would you continue tangential to the circle? or would you be pushed outward by "centrifugal force".
Agree that the physics at 6:34 - 7:00 is wrong. The Fcf force shown is does not exist. An object in motion will stay in motion if not acted upon by an external force. As soon as the athlete jumps, the centirpetal force stops, and, if the athlete jumps straight up, there is no force pushing the athlete towards and past the bar. The athlete is carried in that direction by momentum alone. Other than that, its very useful.
The physics are not wrong. Fcf force DOES exist. If it didn´t the radius of the jumper would be decreasing towards is centre, but centrifugal force is what keeps the radius constant. At the point of take off, centrifugal force surpasses centripetal. The physics ARE CORRECT.
There really is no centrifugal force. The force that keeps you moving in a circle is a centripetal force, pulling you towards the center. The runner applies this force to move in a circular direction instead of straight ahead. If you hit ice, you are no longer able to provide this centripetal force, so you continue along the trajectory of motion as soon as the force disappears. So, you move tangential to the curve if you hit ice.
Because if you hit ice centrifugal force also disappears. One cannot exist without the other. Why do people have such a hard time understanding their correlation?
WTF??? i wanted to know how to get better, not every math equation involved, im not gonna go up there with calculations and spend an hour trying to find the exact measurements.
BTW, this is the best technical high jump tutorial I have EVER seen. I've been looking for something like this for a while. Thank you.

This is the best high jump video there is in YT
Thanks for informative video 👍👍
Very helpful! I'm high jumping this week at sections in MN.
Javier Sotomayor's 7.9m/s Velocity equates to 17.67mph...at that speed, he would cover the 100m in 12.6s THAT'S MOVING!!
Interesting and very informative.
yes, momentum is what what were looking for. along with a easier change in our center of gravity to be thrown underneath the bar.
simonsact very interesting!
This was very helpful in ways
"centrifugal force"
what's the problem
Pablo Cid there’s no such thing as centrifugal force sorry. I was liking this video until I heard it and that’s when I realized this wasn’t scientific, it’s folklore.
I guess you can call it whatever you want. She called it centrifugal force. Whatever you call it, it exists and is a measure of inertia.
my favourite sport is high jump I have go taluk level in high jump

Check the Kurve and angle from Andrey Silnov.

The body weight actually passes under the bar... Apply that however you choose.
I used all of this to improve my baskeball techniques
Better and more efficient than what?
QUE PESADILLA DE VIDEO!!!!!!!!!!!
¡Super super helpfull video! This is lime the bible os High Jump!
1:50
do you have the rest of this video?
I would be impressed if this research had been done while Dick Fosbury was developing his backward dive technique.
I used these techniques and jumped 4 inches higher!
I go 2 inch down 😂😂😂😂........it need practice
I can never believe this
there is no such thing as centrifugal force.
come on Vigors really, 9 minutes!? fer fuck
can you take a look at my page and tell me what i am doing wrong in my high jump video? thanks
The physics part is wrong. Other than that the information is not bad.
lots of math
WTF??? i wanted to know how to get better, not every math equation involved, im not gonna go up there with calculations and spend an hour trying to find the exact measurements.
This is the secret hand shake. You should pass on this as an athlete .
I always boiled this down simply to passing your weight under the bar....
