One thing that doesn't seem to be spoken about a lot however, is the extension of the arm swing to the chest and how this assists in increasing speed (and even efficiency). For example, if the arms swing is low (i.e. stomach height), this translates to an entirely different stride to when the arms swing higher. With the elite athletes (especially the men), the arms swing high up to the chest and this assists the overall dynamics of the stride. I went from a mid-torso arm swing to an arm swing up to the chest, and along with a few other necessary adjustments, this increased my stride length and, it increased my speed. Just curious why there's not a lot of commentary on this small but significant factor.
Motion and the choices you make is highly based on mental comfort. If you feel good in a certain form then it is likely that your motion is optimized by that way of running. Once you get the proper feel for things you like you will get mental stimulation it is a key parameter. It's not all physics the mental component is key in the result. If your mental is satisfied by certain capacities there is a strong chance it will get the physics excited and stimulated so that you can have greater efficiency at certain angles of motion that do not make sense often. That is where you get the odd motion that sometimes uncomprehensively the best of them have it. And I point them, meaning not anyone I know, but those greats like Mo Farah or the runner analyzed in this video.
do one of bernard lagat. He's interesting because he's been able to stay injury free and running at a high level for so long. He made it to the 2016 olympics in the 5000m as a 41 year old which is unheard of and I'm curious if his form is what makes him able to run fast and stay injury free.

Interesting analysis.I think it’s good to see examples of good form like this. However, I think it’s difficult to simply try to replicate what an athlete of this level does based on observation. What you are really seeing is the finished product of years of focused training sessions - long runs, hill sprints, long hill reps, track reps, pyramid drills, strength training in gym, threshold , tempo runs, progression runs, good diet, lots and lots of mileage - easy runs every day, a life based around running basically.
@@sneakerslab2771 Damn, 2 years, a couple of months back (2 months I guess), I did 3,400 meters in 12 minutes, but Im not running anymore (got tired of it I guess), and I pretty sure I can run 2800 meters in 12 minutes. Nuts right?
I'm fan of this guy from when he analyzed Usain Bolt's knee twisting technique from starting blocks... even Michael Johnson missed that best running analysis channel on RU-vid
Interesting analysis. Are you able to make estimates of the vertical oscillation via video footage? It's neat to see the other figures because it offers a direct comparison to my own Garmin metrics (182 cadence, 1.24m stride length, 8.8cm vertical oscillation last 10K... if I could have achieved 2.14 m...).
Great video. I've been working a lot on my midfoot landing, but always had questions on what's happening posteriorly with the legs (i.e. hip extension). One thing I notice is the knee flexion as he brings the leg from behind after toe off. His heel nearly hits his butt. I tend to not have that aggressive of knee flexion. Is this a key component for speed or a personal preference?
What I notice about good runners vs me is their heel almost kicks their bum, my running is much more shuffling and I dont think my feet leave the ground to nearly the same distance
One Insight is that a 5k is probably not the correct distance to analyze unless you are sure it is in the first half, because a 5k is brutal pushing yourself and stride is sure to deteriorate fast.
Great point! I should have mentioned this was actually taking place in the first half of the race. And yeah, usually I talk about the pacing throughout the race to look for signs of deterioration, but i couldnt find specific splits for chelimo
Great analysis. I am wondering how you do to create the lines on the video that moves with the runner. Do you have a specialised software that does that?
Odd question: when your foot hits the ground and you push from the ground to lift you up, are your legs when behind you supposed to be in a 90 degree angle? I’ve seen videos of runners in a complete 90 degree angle and some where they just barely lift up their legs when they’re behind your body.
Ahh, the heel lift as the leg swings forward varies based on speed. Don't focus on that specific part as that will actually slow you down. As you run faster, the knee bend (causing that lift of the legs) usually happens naturally
That’s about 3:42 per kilometre which is a decent speed and there’s no way your steps will be a few inches like you say (this would mean you would be doing 2000 steps a minute) your stride is likely to be 1.5m+ which would be 180 steps/min
I think you've got it backward. What is important does not "start" with foot landing. It's what's happening "higher" up that matters - and results in a certain foot landing.
Have you ever wrote some studies about running gate and /or analysis,? What are you using of base for the analysis? I would be really thankful if you could share some literature. Thanks and great trainings.
I’m really tall but I’ve been slow my whole life. Also always been a terribly slow runner. I would like to learn to run faster. I’d be happy with a 6 min mile even. My fastest is an 8:30 :/ Watching pros run kinda makes me realize I’ve never run to my full potential. But also I have a deformity in my hips that really limits my speed as well.
The foot landing is merely the beginning of the ground contact that ends 20º behind. The majority of the force and work is transferred through the forefoot.
Instead of the boundaries of the ground contact, it would be interesting to see the shape and center of the work curve in relation to the center of mass.
@@ericstrabel I wish I could see the force...unfortunately, they do not put force plates in the track. It would definitely be cool to actually measure the force relative to how close the foot landing is to center of mass
I wish! But there is not enough data during these kinds of races to pull that off. I'd need to measure actual force, which is not possible without a force plate underneath the track
@@pezdacandyboi We can, but limited as overstriding is very bad. Try some hip flexor stretching to increase motions and swing the hands backward passing the waistline, we want to increase the stride backwards, not in front. And higher kicks behind. You can see the Kenyans doing the same here. Goodluck.
Just wonderful, I have been researching "correct track running form" for a while now, and I think this has helped. Ever heard of - Hiymelia Ziyddison Scheme - (do a google search ) ? Ive heard some decent things about it and my cousin got great results with it.
Sorry man, but i just stopped your video at 1.55, there's no way that he covers 2.14 meters per step, if you have a look in good bibliography you'll find that not even a miller goes much further than 1.80 and i'm talking about strong, fast and tall guys.
Sorry man, but you might be thinking of relative step length or something. Even elite runners in a 10k race have can have around a 1.7-1.9 m for step length. You can check the biomechanics studies from the IAAF
How about we just do the math? 13m47s run at 180 steps/min = 2481 steps 5km / 2481 steps = 2.02m/step So well within the range that we're looking for. Now if we use a race where he's going particularly faster and is still keeping his cadence relatively low, that would quite easily put his step length at 2.14m.
Great channel! Just subscribed. Great videos & detailed analysis. Maybe you could review my running form , even though I'm a mere mortal?! Thanks again.
Conclusion: steps faraway from center of mass (wrong) - but run under 14 easily. What does at mean?- there is no absolute correct running technique...I saw 1000 of videos of elite runners, some of them run such terrible and wrong by stupid theory, but f@cking fast...
