How does Body Size affect Sprinting Speed?

[@JasperStringerRunning]

I just want to say I had a meet yesterday, and I ran a 200m PR of 27.92. I know it's not fast but I am going to work hard to get in down to a 21-22 by my senior year. (I am a freshman;15yo)

[@quixmith]

You're on the right track, working on the ground strike and dynamic movements will help. Speed maintenance work by doing some 250 and 300 meters work during your season is also a great way to increase your speed during the finish, also doing high rep and low weight in the gym. You got this! good on you young man.

[@gideonjerubbaalviii]

Go get it man. The mind is powerful.

[@Leonidas-eu9bb]

The title picture shows how muscular Bolt really was especially for his long limbed structure. Bolt has the perfect body shape. Narrow hips, wide shoulders, long limbs, a proximal not distal weight distribution (very important). So Bolt was the perfect sprinting mashine. Guys like Asafa or Gatlin are also pure power in person. But at 6ft 5 and 200lbs Bolt must be an alien period.

[@DimitriTheBarbarian]

His torso is definitely too small compared to his limbs. For ideal body he would need to do bench press and pull ups. I don’t think he had done any of those

[@Leonidas-eu9bb]

@@DimitriTheBarbarian Sry it's about sprinting and power not bodybuilding. Bolt had the biggest widest shoulders of out there without uch if any lifting. He had the genetics of course. Strength training by lifting weights or even calisthenics don't help to run faster. At the highest level it even makes athletes slower because it's very unspecific. For the same reason a strength athlete will not focus on sprints the sprinter should not focus on strength. specificity is very important in training.

[@DimitriTheBarbarian]

@@Leonidas-eu9bb I understand. I was just trying to explain that he doesn’t have “perfect body shape”. He is a great athlete but he is specifically built just like any modern day athlete: their body shape fits best for their specific sports. If we talking about best body shape I would say it’s Decathlon because these athletes have to perform in various disciplines.

I love your work man. The amount of research that goes into these videos 👏🏾

[@chriscodling6573]

Yeah I went from 170lbs to 155lbs and took a full second of my 150m times. There's also the strength in flexibility component. Longer range exercises give you stronger tendons and ligaments which leads to less injuries. So if your someone that prioritizes short range movements and bulky muscle. You might gain explosiveness but your tendons might suffer because the haven't be trained to handle those forces. Therefore more injuries will occur.

[@certifiedchaos4643]

Very true I strongly encourage athletes do a reverse triangle system in the gym. Where u start off with heavy weights low reps. As the weight goes down the reps go up. This will keep u lean increase muscle endurance all while getting stronger, once I did this and dropped 15 lbs man I was running waaay faster

[@jasonphan2001]

Stretching is a myth. It'll slow you down in the race if you stretch before running. Tendon stiffness is the secret to explosive speed. So u dont want to be flexible. There's a reason why men on average are less flexible, it's an advantage physically to have stiff joints & tendons. Think of tendons like a rubber band. A flexible rubber band has great mobility but less force capabilities & is easier to tear than the stiffer rubber band.

[@chriscodling6573]

@@jasonphan2001 lol well the fastest runners naturally are gymnast, so that goes out the window. I think there's a shift between conventional wisdom and new understanding of what makes a great athlete. Where's starting to do more long range movements and it's leading to faster times and less injuries, so you couldn't be more wrong in the subject. Plus anytime I see an explosive athlete that get injured I know they prioritize short range movements over long range ones.

[@ghostpsgaming5871]

At some point we have to understand that its not about a particular physical structure or muscle composition etc. This is a thing based on a case-by-case instance. every person has a unique physical structure which reacts a certain way to certain types of training. you can have a shorter physical structure yet uniquely have superior athletic abilities than certain taller structures that could be classified as having superior athletic abilities. there's no formula really. EG At some point not a lot of people thought a man of Usain Bolt's physical structure could run that quick.

Great video breakdown, I think it's spot on. Now that said would also like to see how among average joes/janes rather professional athletes as opposed to height and weight, muscle fiber composition is the most deciding factor

[@ognyanstefanov8132]

Great video! I really enjoyed it. Only critique I have is that the explanation to why sprinters have skinny ankles was wrong. The analogy was also wrong. If the surface area of the pogo stick was larger, the same amount of force would be transmitted because the spring inside the pogo remains unchanged. The reason why the best runners have skinny ankles is because the rotational inertia about the knee joint is less when more mass is closer to the knee.

[@markthames8999]

good mobility is important for running and it is not always about strength..Take a look at tegogo mobility at 2:04 and you see why he runs that fast while mainting good sprint mechanics/posture

[@Averagebum21]

+Sprint Speed Media Thank you! Very impressive.

[@eamparbeng]

In simple laws of physics, it requires more strength and power to move a bigger, heavier object. This is basically saying that Usain Bolt had to work much harder than the other sprinters to run the times he did. He was literally a sprinter in a basketball player's body being the same size as Michael Jordan

[@vaticinus]

Top Sprinters have the best bodies in all of sports. Sprinting is the most accurate measure of physical fitness.

[@joshuadavis5899]

They have the best body for sprinting but not for long distance running, swimming, climbing, weightlifting, jumping etc practitioners of all those sports are physically fit. There is no superior sport.

[@raymondsmith2040]

joshuadavis5899 I think he means they have the best bodies that can transfer to alot of different sports. Alot of non-olympic sprinters can (some very successfully) became good American football and rugby players. Sprinters have incredible strength for their body size meaning they would probably do good in powerlifting. They're technically coordinated (though not genetically gifted) for weightlifting. Lean enough to be decent at swimming. List goes on.

sprinter body type guide

[@FrogmortonHotchkiss]

I find the 'thin extremities' explanation a bit confusing and unconvincing; could it not rather be that it's easier to swing a stick that is thin at the far end? Bowyers and archers understand that a bow needs to be thin at the tips if the stored energy of the drawn bow is to successfully transfer into speed. You might think that thick tips would mean even more potential for stored energy so be a net gain, but no: the increased tip-mass slows the speed with which the tips return to straight on release (of the string), which results in a slower arrow.

[@energyzer_bunny1913]

I'll be the 1st person to tell you, bulking up for sprinting is OVERRATED! It's better to not be big enough than it is to be too big. Once you gain muscle, you're likely not going to lose much of it. Sprinting promotes muscle growth. You may lose a few pounds of fat but you're likely to maintain most of your muscle just by sprinting alone. My resistance training now mainly consists of resisted sprints, hills, and weighted jump/plyometrics. Adding more muscle especially hinders you in the longer sprints.

[@MajSolo]

I spent a whole day watching Bolt clips , so I thought that long persons can get higher top speed if they have the muscles move those long legs. If you look at it as a technician smaller hip results in less work with arms. Though I wonder if blood in the arms have time to get to legs in 10 seconds , maybe it don't matter.

[@davidms3729]

Steroids don’t affect all the same way, what they usually do produce on most people is very developed traps and a shoulders (even without specific training) so some of them even though are quite skinny/athletic still have those parts very developed

ok, but there is something not kept in mind, the number of miofibers, two miofibers produce more force than one, and it is not necessarily reflected in size

There were other tall sprinters on the track with Bolt and he was faster than them (Ryan Bailey was 6'4 and couldn't catch Bolt in any race). Bolt was only a couple inches taller than Asafa Powell and many of the other tall sprinters he faced. Tall doesn't make you fast (there are taller sprinters today that aren't close to Bolt, the closest is Fred Kerley at 6'4 who ran 9.76 last year). And you know his name is Usain not Hussein right? His advantage was being powerful and quick while being tall but that wouldn't matter if he wasn't powerful and quick in the first place.
