That's not what I saw. I saw his immense power, excellent body mastery & technique. His strides were obviously long bc he has long legs.

@@biggalaxy9102 I never said being tall and having long legs makes you fast.. I said I noticed that with Bolt, his legs aren’t moving as fast as you would think they are.
Longer legs make you go faster because they can take bigger strides, but they swing slower, because of simple physics: the longer the pendulum (like that of a clock), the slower the swing. So it is actually quite astonishing that Usain Bolt could move his very long legs as fast as that.
@@TrentonCS Yeesss.... the trick is that with longer legs you can make *larger strides* (more meters per step, so to say...) so that with the same or even a lower frequency (how fast you move your legs forward and backward) you can still go faster. No contradiction there.
I think for athletes we know what this video us talking about. We are talking about power into the ground creating force in a forward angle that results in low contact time and therefore greater stride length and hence speed. This is obviously done through technique in training. However beginners and new runners do not understand these concepts by default. Often their stride is inefficient and if they are older will cause injury and drive them to want to stop. Instead what they hear us long stride = good hence they will start with trying to over stride.
To answer the original question, one of the sprinters with one of the fastest turnover rates ever was Kim Collins, who was 5'11 "and 160 lbs. The "Jumpman" RUclips channel has a good video on him if you want to know more.
I think the maker of this video might be confused about the term ‘speed’. What he is saying is the same is close to what physicists call rotational velocity.
Thanks for your comment! In the video, 'speed' refers to forward (linear) velocity in sprinting. While leg movement does involve rotational motion, the main focus is on how sprinters use power and stride efficiency to maximize their running speed. Appreciate your input!
thx this is gonna help all my friends say i run goofy but can't describe how, i always feel like i'm pushing my legs to move faster than is possible and getting no force out of them i think this is probably it
But elite sprinters do achieve higher thigh angular velocity and amplitude not just at ground contact, but also during flight. Your mistake is thinking swing time represents limb speed. Even if swing time is same (surprise surprise, it’s NOT), the amplitude being greater, means the leg is moving through greater distance in the same time, that means higher velocity. Not to mention the directly measured higher angular velocity of elite sprinters, it is undeniable that they move and reposition their legs faster. And yes, they also achieve greater ground reaction forces and shorter GCT.
Appreciate the thought behind this, and let me help clear a few things up. The key misunderstanding is conflating higher angular velocity and amplitude with faster leg repositioning. While elite sprinters do achieve higher angular velocity, this doesn’t mean their legs reposition faster because swing time-the actual measure of leg repositioning speed-remains consistent across all runners. Research has consistently shown this. The higher angular velocity simply reflects a greater range of motion within the same time, highlighting their efficiency and biomechanics, not an increase in repositioning speed. Take-home message: Elite sprinters don’t "move their legs faster." Instead, their speed comes from superior technique and power, allowing them to cover more ground without altering swing time.
In the study this videos mentions, swing time is calculated as the time between foot contact and next foot contact of the same foot. The study concludes there isn’t a clear statistical significance of relationship between swing time and air time, to max velocity. That does not mean swing time is the same for all participants. As matter of fact, the data for each participants shows variation in swing time. But that’s not the worst mistake of this video, it’s conflating swing time with how fast sprinter move their legs. To move your thigh through a greater ROM in the same time, you have to achieve greater limb velocity, it’s basic math and physics. Object A move from one point to another, takes the same time as object B, but object A had to travel a greater distance, it means object A had to do so at higher velocity than object B. In this case the time it took to travel is the same for both, but difference in distance means difference in speed. Please do not misinform in the general public.
@@OutperformOfficial Serious question. Are you comparing elite to sub elite or are you inferring that the general population can take 4.5 strides per second?
As a young runner I had super leg turnover. When we did speed drills the kids used to line up to watch my legs blur. I could turn an exercise bike at over 300 revolutions per minute when it would stop reading as I was off the charts, yet I wasn’t the fastest sprinter. In fact it helped my distance running with a killer finish as those small rapid steps never stopped but I was confounded as to why I could not sprint 100m. Was just average quick, nothing special.
Thank you! Great question-while there’s no single formula, the fastest man in the world typically has a combination of explosive power, excellent biomechanics, optimal stride length and incredible mental toughness. For physical characteristics - fast-twitch muscle dominance, an efficient body composition, high power to weight ratio etc. Ultimately, it’s the perfect balance of genetics, training, and mindset and some luck (no major injuries etc)
Oh so this is what caitlin was explaining to Barry about he, zoom and reverse moving their legs at the same speed, but the time their feets stay on the ground defers. I really didnt understand that part when I watched it then, wow nice.
You got it. Shorter ground contact time combined with greater force during each step is what makes the difference in speed. Glad the video helped make it clearer!
I once read about stride length, and stride frequency in a book. I wish I had known this about stride frequency before. I was able to increase my speed a little, but I probably didn't develop my power sufficiently enough.
This is objectively false. While it takes the same time to cycle the leg from take off to landing, elite sprinters cover greater distance in the same stride. While this is proof that they produce greater power at foot strike into the ground, mathematically to cover a greater distance in the same time means the swing leg has to achieve greater velocity in the air. So elite sprinter do move their legs faster, and they produce greater power into the ground as well.
Thank you for the comment! While elite sprinters do produce greater force at foot strike, the idea that they must swing their legs faster to cover more distance in the same time isn’t correct. Research shows that swing time (the time to reposition the leg in the air) is nearly constant across all sprinters, from amateurs to elites like Usain Bolt. Here’s why: stride length increases because elite sprinters generate higher ground reaction forces, propelling their center of mass further forward during ground contact. Sprinting speed is defined as v = Stride Frequency × Stride Length - the increase in stride length comes from greater ground force, not faster leg swings. Stride frequency is limited by the combined time spent on the ground and in the air, with swing time being a relatively fixed portion of the cycle. The swing leg velocity adjusts to maintain coordination, but it’s not the key driver of speed. The primary determinant of sprinting speed is ground reaction force, not aerial leg speed.
@ But elite sprinters achieve higher thigh angular velocity and amplitude not just at ground contact, but also during flight. Yea swing time is identical, but your mistake is thinking swing time represents limb speed. While swing time is same, the amplitude being greater, means the leg is moving through greater distance in the same time, that automatically means higher velocity. Throw in higher measured angular velocity in air, it undeniable that they move and reposition their legs faster. And yes, they also achieve greater ground reaction forces and shorter GCT.
Longer legs have *both* an advantage and a disadvantage. The advantage of longer legs is that you can run the same speed with a lower stepfrequency and less effort (higher efficiency) so that you get less tired.... The disadvantage is that longer legs have longer levers, wich makes you less explosive. In other words: a runner with longer legs will be a bit slower from the starting block.
More time on the ground equals less time flying through the air. Think about trying to run while always keeping atleast one foot on the ground. You’d be much slower. You’re the fastest when you cover more ground in the air (efficiently)
longer legs make your strides wider. i knew gout gout would beat usain at his age bc nilotic africans particularly have proportionately longer legs, aside from being tall like the dutch for example. a 6'4 dutch guy would probably be taller sitting down than a 6'4 south sudanese of gout’s background. (taller upper body vs taller legs)
Ha! Being 6'5" and Jamaican definitely worked out well for Bolt, but stride length is just one piece of the puzzle-technique, power, and hard work play huge roles too. While no one seems likely to match him anytime soon, everyone has the potential to get faster!
Sprinting is basically plyometric. It’s bounding. So although moving your legs fast is a good thing, it’s more like the icing on the cake. The base is being able to apply enough force to the ground as quickly as possible to cover as much distance in efficient time. Simply just making your legs move faster doesn’t cut it. Hope that makes sense
Then how come there are sprinters who take closer to 50 strides to do 100 metres but are within a couple of tenths of the WR? They should be miles back. Speed is a combination of stride length, frequency and amortization (time spent on the ground).
Great question! Elite sprinters typically take fewer than 50 strides for 100 meters-usually around 41-45 strides. For example, Usain Bolt took about 41-42 strides due to his long stride length, while shorter sprinters like Tyson Gay and Yohan Blake took closer to 44-45 strides.
Great question! Actually, elite sprinters and athletes swing their legs at roughly the same speed. What truly sets them apart is how they utilize that leg movement-through more powerful strides (applying more force to the ground) and efficient technique.
Speed is like a 100mph fast ball; only a few can do it no matter how hard you train. Stop telling slow people or average people they can run faster with technique and hard work.
Very few people can reach world-class speed in sprinting or pitching, but that doesn’t mean you can’t do the sport, enjoy it, and get better. With the right technique and hard work, anyone can improve beyond where they started-whether you're a JV pitcher aiming for spot on the varsity team or a masters sprinter trying to go from 14 seconds to 13. Progress is possible for everyone!
You're right, we didn’t directly answer that in the video. While leg swing speed is similar across elite sprinters, it’s the power and efficiency of their strides that really make the difference in speed. Hope that clears it up!
I don't even know what you mean by "fastest leg swings". You mean cadence? Or do you mean the actual velocity of the foot during the stride? Just say cadence if you mean cadence.
Great question. Cadence (steps per second) and leg swing speed (velocity of the leg during the swing phase) are different. The video focuses on leg swing speed because the misconception is that elite sprinters swing their legs faster in the air. In reality, leg swing speed is similar across sprinters, and what sets elites apart is greater ground force, which increases cadence and stride length. That’s why the video avoids using "cadence." Thanks for bringing this up!
I'm frustrated guys I love running but I'm not very good at it My family laughs at me after my little brother beat me in a 3km race I did 16 minutes but he did 15:58 knowing that he has been playing football for a long time so he trains Regularly while I started 4 months ago 🗿 hhh
What a dumb conclusion. Your leg moves the exact speed as your topspeed. So the fastest sprinter has the fastest speed. You are talking about the leg FREQUENCY.
Thanks for your comment! The distinction between leg speed and frequency is important, but the video isn’t just about leg frequency-it’s about clarifying the mechanics behind sprinting speed. You are right about the overall motion of the legs matching the forward velocity of the body (since they’re part of the moving system). However, this doesn’t mean that elite sprinters are swinging their legs faster in the air than slower sprinters. It’s the ground phase, not the swing phase, that drives performance.
@OutperformOfficial The backward speed of a foot, when it touches the ground relative to the body is exactly the same as the forward speed of the body. It just doesn't make sense what you say.
Thanks for your comment! You're right-more power from each stride definitely contributes to greater speed. The main idea of the video is to help people understand that sprinting isn't about moving your legs fast, it's the combination of power, stride efficiency, and technique that truly sets elite sprinters apart. I hope this clarifies things.
Then why do all fast mammals spend more time on the ground then in the air? Its because you need to be on the ground to accelerate. This is why animals like the cheetah are fast, they spend a lot pf time in the ground when running to accelerate, and they have all 4 limbs on the ground aswell. This is unlike humans which only use 2 legs, and when they run they usually spwnd a lot of wasted time in the air, perhaps if humans were used to running on all fours, maybe they could be faster.
Actually at top speed, cheetahs have very short ground contact times-typically around 0.05 to 0.06 seconds per paw during their sprints. This allows them to accelerate quickly and reach incredible speeds (here is a really cool video showing a cheetahs running technique ruclips.net/video/B4nd9GF1dRg/видео.htmlsi=Gmdtmk8in5MGNYXr) Humans, on the other hand, are bipeds with different anatomy and running mechanics. We rely on powerful strides and efficient technique to maximize our speed, rather than just increasing leg turnover.
@@originallyturtle7470 Just a possibly incorrect impression because elite 100m women tend to be on the short side and seem to make up for it with fast turnover. I'd be happy to be proven wrong tho.
@@elizabethhenning778 You said it yourself, short women tend to have fast turnover, except Short men tend to have a fast turnover as well. It's less about gender and more about body type
Then why is the second fastest man in NFL history only 5'5" with a 10.00 twice & he was significantly faster than the rest of the taller men in NFL history? BTW, his name was Trendon Holliday. The 3rd fastest man in NFL history was 5'7" & was the fastest RB in human history at any level. His name is Jeff Demps 10.01. Let's take Randy Moss, who's PB 100m time was only a 10.94. Tyreek Hill 10.19 makes him only the 24th fastest man in NFL history & he is 5'10". So no, long legs aren't important. Speed is important & there are so many important factors that go into this. Height & leg length have very little to do with it.

You are right about the overall motion of the legs matching the forward velocity of the body (since they’re part of the moving system). However, this doesn’t mean that elite sprinters are swinging their legs faster in the air than slower sprinters. It’s the ground phase, not the swing phase, that drives performance.
@OutperformOfficial
The backward speed of a foot, when it touches the ground relative to the body is exactly the same as the forward speed of the body. It just doesn't make sense what you say.
More power from the strikes, equals more speed. Why are you make it so complicated?
Thanks for your comment! You're right-more power from each stride definitely contributes to greater speed. The main idea of the video is to help people understand that sprinting isn't about moving your legs fast, it's the combination of power, stride efficiency, and technique that truly sets elite sprinters apart. I hope this clarifies things.
He made it quite simple .why are you over complicating it in your head ? That is the real question.
Then the entire premise of the video is wrong, how do you not see that?@@diesel961
What the hell is your animation was😅😅😅😂😂
Okay no response
Lol men wearing leggings 💀💀💀
su bingtian moves his feet faster..?
His height and legs proportion are shorts compared to other athletes ,
Azeem fahmi
Well yea cuz hes 6'5
Then why do all fast mammals spend more time on the ground then in the air? Its because you need to be on the ground to accelerate. This is why animals like the cheetah are fast, they spend a lot pf time in the ground when running to accelerate, and they have all 4 limbs on the ground aswell. This is unlike humans which only use 2 legs, and when they run they usually spwnd a lot of wasted time in the air, perhaps if humans were used to running on all fours, maybe they could be faster.
Actually at top speed, cheetahs have very short ground contact times-typically around 0.05 to 0.06 seconds per paw during their sprints. This allows them to accelerate quickly and reach incredible speeds (here is a really cool video showing a cheetahs running technique ruclips.net/video/B4nd9GF1dRg/видео.htmlsi=Gmdtmk8in5MGNYXr)
Humans, on the other hand, are bipeds with different anatomy and running mechanics. We rely on powerful strides and efficient technique to maximize our speed, rather than just increasing leg turnover.
Copy and adapt
This is probably somewhat less true for women
Not really. Same thing applies
how
@@originallyturtle7470 Just a possibly incorrect impression because elite 100m women tend to be on the short side and seem to make up for it with fast turnover. I'd be happy to be proven wrong tho.
@@elizabethhenning778 You said it yourself, short women tend to have fast turnover, except Short men tend to have a fast turnover as well. It's less about gender and more about body type
@@Rayan2track But short women seem to be a much higher proportion of elite women. That's not true for men.
Thifsh it thirrd lmk knife
Wrong
Ote
Usain Bolt can run 100m with 41 strides because of his long legs. So, long legs is important
Then why is the second fastest man in NFL history only 5'5" with a 10.00 twice & he was significantly faster than the rest of the taller men in NFL history? BTW, his name was Trendon Holliday. The 3rd fastest man in NFL history was 5'7" & was the fastest RB in human history at any level. His name is Jeff Demps 10.01. Let's take Randy Moss, who's PB 100m time was only a 10.94. Tyreek Hill 10.19 makes him only the 24th fastest man in NFL history & he is 5'10". So no, long legs aren't important. Speed is important & there are so many important factors that go into this. Height & leg length have very little to do with it.
