The coach at Auburn University, which has excellent sprinters, apparently coaches them to get up into their running much early, similar as you mentioned with the french sprinter Vicaut
Great video. I just want to add something. Nothing major. When exiting the blocks. There's a moment where the front leg reaches full extention and you can draw a line from the foot to your head. It's called "Triple extension". Triple because the 3 points that are lined up are your feet, hips and head. In fact the thumbnail in the video is exactly that.
everybody knows what it is! Triple extension should not be intended for an effective start by the way. Indeed it's a big mistake to fully triple extend, because it's more efficient to quickly recover instead!
Yeah Powell mentioned that recently on his own podcast when he sat down with Maurice Greene, Linford Christie, and had Gatlin moderation mostly off camera as well Gatlin's co-host (forgot his name other than "The Bearded Wonder" lol). Powell specifically said that guys like him or Bolt would toe drag sometimes cuz they are big guys trying to stay low out of the blocks. It was not done purposefully of course but some of these guys online and some young sprinters don't know that and think if you don't toe drag you're doing it wrong smh.
I think you are wrong about the forces. Horizontal force is always the most important force. At top speed horizontal force must be still present because of wind resistance and breaking forces in the early stance phase. More Vertical force doe NOT make one faster. It's just necesscary to get enough fligth time to reposition the limbs. Faster sprinters are able to create more horizontal force in relation to vertical force. That means at the same running velocity they apply more horizontal force. Longer legs are an advantage to achieve a higher top speed because longer levers make it easier to produce more horizontal force! More horizontal force = more horizontal speed!
That sounds right in theory but it's been demonstrated that's not always the case. I'm not sure if it was this channel or another one but there was a clip in a video demonstrating the importance of vertical forces showing a pro sprinter (can't recall who it was) doing straight leg bounds on an ice rink. To do this on ice they only focused on putting vertical force into the ground otherwise they'd risk slipping and falling. This propelled them forward and they performed the bounds flawlessly. It may have been Marcel Jacobs but doing this drill but not 100% sure.
@@gmaxsfoodfitness3035 Don't get fooled by those! Just use your mind. It's totally ridicolous that there are so many people believe this nonsense. If you have just some basic understanding of physics, it should be totally clear. One simple rule. Moving mass into a direction needs force into that direction. This holds true for everything from us to animals, cars, planes, planets,... And the direction is mostly horizontal in locomotion!
@@Leonidas-eu9bb I agree that horizontal force is important but it is true as well that you need less of it when you get to your upright sprinting. The most horizontal force is at the start of the race and it decreases as you get into top speed. He shows the percentages on screen so this was calculated somewhere and may be an estimate but there seems to be a point there. Whether you need only ~6% horizontal force later in the race I'm not sure of but you probably don't need 40 or 50% anymore since you already created enough horizontal force early on to get you going. After that you only need to maintain enough horizontal force to keep going. Remember sprinting is different than walking or even running. You are bouncing off the ground more and ideally you want more air time than ground time. Horizontal force won't get you off the ground. You need vertical force for that. You need some of amount of both to move forward AND get off the ground. Too much horizontal force will make you fall flat on your face so the vertical force is what keeps you upright and gets you off the ground. You need enough for both of those. You only need enough horizontal force to keep moving forward. Just looking at those 3 points (staying upright, bouncing off the ground, and moving forward) you can see that vertical force is dominant once you are already moving forward which is why this is effective only when you are already at speed. The key point is that once you already have substantial horizontal force to get you going then you need more vertical force to keep you upright and off the ground. That's what I think you're not understanding. It's not that horizontal force isn't needed or wasn't dominant to get the object in motion. It's that you don't need as much of it to keep the object in motion which is why it decreases throughout a race.
@gmaxsfoodfitness3035 omg you still don't get it! Horizontal forces decrease when running speed increase because it becomes harder and harder to generate horizontal force! So it the limiting factor. It's not a question of do we need it. More horizontal force is more horizontal speed!! The longer one can generate it the higher ones topspeed is! The whole reason why we run upright is because it's the most effective position to produce horizontal at high speeds. Vertical forceis not the limiting factor because gravity and mass doesn't chance! It's totally possible to aplly large vertical forces but running slow or even staying in place. It's called vertical jumping.. Maybe you need more simple logic. Why do we run faster with tailwind and slower with headwind.. Wind is only horizontal force! You car won't go faster with more vertical force. But it will with more horizontal. I even made a test with athletes where we measured horizontal limb velocity and running speed. The correlation was almost perfect!
Vertical force is critical for generating the necessary ground reaction that enables horizontal propulsion; without adequate vertical force, horizontal force application becomes inefficient. Additionally, flight time for limb repositioning is intertwined with vertical dynamics, not separate from them. In fact, sprinters produce far more vertical than horizontal force at top speed.
At 7:07 I meant to say Horiztonal Forces not Vertical
Doesn’t matter bro!

Nice step by step guide, looking forward to the next part
Love this channel so much

5:10 on Gatlins podcast Powell addressed that he absolutely doesnt/doesnt intend to take drag in competition

Can you make a video about ben johnson rocket start?
Bro,plz make video about how to qualify in European games and european athletic championship seperately?? And keep it up u r doing nice work..

how do you spell the name of the sprinter who ran a 9.88?
Jimmy Vicaut
@@quadecooper8508 thank you sir
This is so helpful thanks
3:48
Good advice
Thank you!
That is not the most efficient way to start the problem is leaning forward at the ankles shoulders joint hips joint and ankles joint in line is good
Should the ankles remain dorsiflexed during the first few steps ?
