How sprinters use biomechanics to push the limits of the human body

- The biomechanics of sprinting is one of the most complex things I've learnt about. Every source has their own opinion about how to move the legs, arms and body but almost no one backs up their opinion with proper science and mechanics. So I wanted to make this video to help you understand how certain techniques taught to elite runners helps them push the human body to the limits. The great thing is that the techniques here can be utilised by any runner, regardless of skill level.
I'll be discussing the acceleration phase and maintenance phases of sprinting. The aim of the acceleration phase to create an aggressive forward lean to maximise horizontal force production whilst ensuring there's just enough vertical force to keep your body from stumbling. For the maintenance phase of running, you want to land with your foot underneath the center of mass, push off the ground using your entire posterior chain of muscles and finally you want to minimise the moment of inertia of the leg in the recovery phase.
There's a lot that I didn't have time to cover in this video (e.g. how to push off the blocks at the start, how to move the arms correctly etc). So if you would like to see a part 2, let me know in the comments!

As an Olympic sprinter & full time nerd, this video deserves a hearty endorsement. Great summary of the biomechanics of sprinting. I've been wanting to do a sprint video for a long time, and I'll likely refer back to this one as a foundational resource. Great stuff!
Bro didn't you qualify because your country is so bad and didn't have any qualified Olympians and you just run 100 in 11 sec that is like high school shit and you call yourself Olympic sprinter.
Hi Crumpton Daly. I took a slow motion video of my 14 year old son sprinting. He is a high level soccer player but his speed is only average. Since you are an expert on sprinting, could you please take a quick look and see if you can notice any improvements he can make to his technique. We'd be extremely grateful.

Seriously dude, 11,17 ? This information is NOT going to make anyone sprint faster. The dude is still learning about sprinting and is underestimating its complexity.
@@SprintClub-xi4ybu make a video then explaining how to scientificly run the fastest
I Don have to make a video. I make people run faster every day . This year alone my athletes won 8 national medals and 2 International medals. 3 became national champions !
I know a thing or 2 about sprinting.
The quality of your videos is mind blowingly good for such a small channel ! Keep it up, the algorithm will do it's thing one day
Please do the second video about the block start and arm movement!! Upvote if you agree.

I’m on my second season as track as a freshman, this video guided me so much. Great stuff!
part two? o.o I have been watching videos all over yt about body mechanic of sprint/run but yours was the first one to include maintenance and acceleration phase! and they are so important! tank you !
The way you explain this is really awesome! Easy to understand, good and enough visual examples (I for one would pause even more when showing these, because they make things easy to understand). Congrats!
Will you make a video for the biodynamics of skiing? I would really love to see it. And please, don't skip any details, as I know it's quite a complex sport.
All the best,
Emil
The start is called The Drive Phase!
The Acceleration Phase is the next Phase! .
The Maintenance phase is the Final Phase.
Would love to see part 2. As a track coach who also teaches kinesiology students I was looking for a good video to help explain sprint mechanics and this was such a great video. Thank you!
Im from South-Afrika what is the cost to see part 2
Super informative Video!!! They're very well done :) Initially brought here by your climbing Posts
How isthis channel so small ? Never in the last 4 years of watching fitness/sports related channels have I seen biomechanics explained this well
Thanks Pablo !
Such a great summary and so well put! Is Part 2 available yet??
Its finally clicking! Thank you very much
This is really helpful. keep up the good work
Great video as always!
Great video, hit such key points in such a short amount of time!
Love the channel, part 2 please. Thanks!
I would love to see videos where you cover Mixed Martial Arts (MMA). Aussie Robert Whitaker vs Kiwi Israel Adesanya part 2 would be a good one.
New runner here o/ inspired by the Olympics Just had to let you know this video was awesome! Way better detail, clearer explanation, and more entertaining than the dozens of other running form videos I've been binging. Excited for part 2, 3, etc. I'd love to see a vid on the biomechanics of cycling
Glad you enjoyed it!! More videos in the works :)
Nice video 💪🏽 Pretty insightful.
I’d argue the lean in early acceleration is a result of force production more than a cause. Elite sprinters have low projection angles because of how much force they can produce, not the other way around.
Athletes who try to go lower than their force outputs allow tend to reach and crash at ground contact.
Anyways thanks for the great video!
How do I keep my shin angles low at the start
You practice. You do drills , you pull heavy sleds . You lead with the knee and keep a tight 90° angle or less
@@SprintClub-xi4ybgreat info👌
This video definitely needs part 2
Great video! Thanks
Best explanation thank you!
Great video!
Very interesting video. Keep going ♥
Very informative video ❤️❤️
part 2 ASAP ! :)))
Thank you Doc! Alot of useful info in just 7 minutes. I will run better now!
Good video
good vedio. much love
Need more....
thank you
Analyze biomechanics of kayaking please!
The strong lean off the blocks is needed to accelerate, but all the horizontal effort later is to fight wind resistance, and that needs body in front of driving foot too.
Nice video
All of this takes at least 7/8 months to physically burn into ur muscle memory. After that u have to figure out wat, out of all the biomechanics etc, works best for u. Ul def experiment with midfoot strike & think thats the b all end all to apply force, then months in, ul find ur mind rejecting it & by default find urself wanting to forefoot strike, & maintain it without ur heels touching.
The mind will always figure out wats most sufficient the more u do something, & the longer u keep at it. Natural adaptation - in other words, keep training, keep learning, combined, it'll render results eventually - even for the less physically gifted... Every1 has that sweet spot embedded - keep digging, ul find it
I mostly agree, but the low heel recovery during acceleration is not the fastest path just because the foot travels less. When the foot is close to ground, there more torque needed to flex hip. The reason is can help is because it creates more momentum which propels the sprinter forward but you need strong hip flexors to do this so it’s not ideal for everyone
Can you make a video on how to strike the ground with force?
Aye I know the track in the first clip. That’s Green Point Stadium in Cape Town South Africa!
Thank you!
I searched for part 2, but had no luck.
How would you discuss the biomechanical factors, specifically the angular kinetics, that influence the ability of the thigh, leg and foot to rotate about the hip joint during a sprint stride. Identify specific of the factors during full stride ?
Here's a comment and a like for the all-mighty Algorithm. Solid video again
I have to imagine that the forward lean is to counteract wind resistance, which is huge at 26 to 27 MPH. The videos of sprinters on treadmill force plates seem to show a much more upright angle.
Isnt Part 2 available yet?
Everyone be talking about feet and leg power but never noticing that the head drops the bodies mass like dropping a 5kg weight onto the scales it spikes above way over 5kgs. All animals load the jump and run/sprinting with lowering the head and raising it to force sprint/run mechanics.
I can’t find the arm swing video. Link please
Good video, but the phases were all mixed up. He confused the "acceleration phase" with the "drive phase", as an example. Could be because I coach in the US and he is coming from a European background. Overall, it was good and touched on some good points. However, it's always interesting to hear a biomechanistic vs a sprinter explain sprinting techniques.
What program is he using to show the muscle movements?
hi i have a physic project , i gotta talk abt the physic concept behind running ,,, can i chose biomechanic
How about long-distance running biomechanics, they use the foward lean more
🙌🏻🙌🏻🙌🏻🙌🏻
Where is part 2????????
You got peer reviewed articles for this?
Sir so we should not lean forward while sprinting
I can't understand why even though the ideal place to land is under the center of gravity in real life no one really does it. Is it because it is necessary to land in front so that the muscles have enough time to push off the ground? And also that's why sprinting has a lot to do with genetics because max velocity is related to how fast you can push off the ground thus dominance of fast-twitch muscle fibers type?
It's because at speed your center of gravity is not under your hips. The velocity moves is a little infront of your center
Its to do with the time the feet are on the ground determining the right kind of angle for plyometrics. As the head drops a little this accelerates your mass down into the feet initiating the stretch flex cycle. You spend too long loading it on the wrong angle it will hurt, too little on the wrong angle it will hurt. The brain learns quality with practice and patience. Or just learn to use your head to move your mass, this will teach you exactly what you want.
Adequate biomechanical analysis, after 25 years of professional sport and 6 orthopedic surgeries, you can ask yourself... does technique matter and what it really means. Regards, Damian
Who told this guy that the acceleration phase is block clearance?
🤔 then how is Naruto so fast ??
You are missing an important point at the blocks.
Nope ! Biomechanics 101 at top speed the forces are VERTICAL not horizontal!
Show specifically where foot strike occurs directly under the CoM.
This is a myth.
Good video but I don’t understand about there not being any science out there. That’s not accurate. There is tons of science backing this in professional coaching ranks. As a matter of fact every certifying body teaches the science behind this. ALTIS, USATF, IAAF… etc. The issue is too many coaches won’t pay to get not only the knowledge but the science behind the knowledge! Lol, every world class sprint coach, coaches these models.
Please . Translate . Hindi language
So , nice try but I can see you're not a sprinter or a coach or a biomechanist for that matter. Much of what you have said is true but much is not.
No one will sprint fast with your model. You're teaching how to run instead of how to sprint. Sprinting is a series of jumps over the ground. Horizontal forces become mostly useless at top speed. The focus is more on vertical forces.
Love the channel, part 2 please. Thanks!
