“Obsolete spike-shoe technology” is crazy
that's what it is
I used the ASICS and liked them. But, you can’t use them on all tracks. There needs to be some give in order to get the shoe to grip the track.
How did your hamstrings react?
I think it takes a little bit more than the right footwear to run 42.5.
that's what you think
yeah you'd have to be more than just an elite athlete for it to work like that
@@lol-gb5vt elite level is enough
lack of friction or grip would make it extremely difficult to accelerate out the blocks
no spikes don't mean no friction.
Can speak from experience, it was so bad I stopped using them after 1 practice.
@@jackm727version without spikes?
@@user-zj4kb7is2k yes without spikes
Agreed that’s why some coaches argue that athletes should work for longer wearing spikes where speed is concerned and less for distances over 150m but others argue you have to work the muscle
I completely agree that "spikeless" sprinting spikes are theoretically better than spikes; however I also disagree with the mechanism described for hamstring injuries. Yes -- Spikeless spikes are theoretically superior for top speed because (i) They should be lighter; and (ii) They should have less "vertical" friction on releasing from the track at the end of foot contact (i.e., the shoe is not "stuck" to the track as the runner attempts to push off). So I agree 100% with the overall conclusion that these shoes should be superior.
However, on the issue of spikes contributing to hamstring injuries -- The mechanism described does not make sense. This video correctly describes how the foot is moving forward, relative to the ground, on ground contact... and therefore, "too much friction" causes the foot to jerk *backward* a tiny amount. But this cannot overstress the hamstrings, because the foot is being suddenly accelerated in the same direction that the hamstrings act to move the foot (which is backward relative to the hips). Thus, there is a sudden *decrease* in the tension on the hamstrings due to the friction with the ground on ground contact. Not an increase. If the mechanism described were to cause injury, such injuries should manifest in the anterior chain (quadriceps & quadriceps/patellar tendons), not the posterior chain.
The reason that hamstring injuries occur during the period immediately before ground contact is due to the rapid opening of the knee angle as the leg accelerates downward. The ground actually helps "prevent" injuries to the hamstrings, because the ground helps the hamstrings stop the opening of the knee angle before it reaches the end range.
Spikes may "contribute" to hamstring injuries only because they aid in increasing speed, and increased speed means an increase in the degrees per second of knee angle opening shortly before ground contact (and a concomitant increase in the eccentric forces acting on the hamstrings).
That's very interesting point. How do you explain that hamstring injuries never happen on grass?
@@TheWayToWin It's a matter of speed and purpose. The eccentric forces on the hamstrings due to knee-angle opening are dependent on running speed; the faster one runs, the higher the forces. Track sprinters are unlikely to get injured on grass because (i) They have conditioned their bodies to tolerate higher speeds than they are able to achieve on grass; and (ii) They don't do their most-intense workouts on grass.
Field sport athletes still injure their hamstrings on grass, because (i) They *do* do their most-intense running on grass; and (ii) They generally don't expose themselves to higher speeds via sprinting on a track (which would condition their hamstrings to handle those higher forces and cause running on grass to become submaximal in all circumstances).
@@TheWayToWin Hamstring injuries definitely happen on grass. The first two times I ever pulled my hamstring were both on grass. Ball sport athletes pull plenty of hamstrings in games.
@@tracktuary Players wear cleats to stop their foot too quickly. Not that I am against spiked shoes; they just should be used wisely. Runners need spikes only to accelerate and make turns. It's absolutely unnatural and just wrong to have spikes throughout the whole race. Cheetahs extend their claws only when accelerating and changing direction. They would ruin their legs if they had spikes on their soles..
@@TheWayToWin I agree that there is an epidemic of track athletes using inappropriate spikes, such as 5k runners using 1/4” spikes on a dry surface. Complete overkill, and counterproductive.
Honestly, I have the ASICS Metasprint spikes and whilst I bought into the theory of how they were designed to work, in addition to loving how light and stiff the plate is. I definitely felt I had a lack of grip in them and consequently ran slower. Albeit, my mechanics are flawed and I do tend to land slightly over my COM, which may have lead to the drop off in performance. As it is obviously harder to pull back with spikeless sprint shoes.
I always though that spikes are wrong on a dry track surface.
It's interessting that many athletes can sprint as fast and more efficient barefoot if the surface is optimal. Acceleration suffers when running barefoot but upright running is easier.
Really cool video. Thank you.
thanks for watching!
Look into the 1968 brush spikes that Puma made for John Carlos. Interesting relevant story on minimal spike inovation (that Adidas had banned bc they suck at innovation). There's a great story on medium about them: bristles instead of standard spikes helped Carlos brake the 20 second barrier for the first time in history after running a 20.mid the day before in standard spikes. Vince Matthews and Lee evans also broke the previous 400m world record in them.
It seems having various small bristles is beneficial over standard pins, but I'm not sure what this says for your theory because they were supposedly MORE grippy than standard spikes. It could be that, even in the 200, the benefits that increased grip have in acceleration outweigh any potential nagatives of premature stopping of forward motion of the foot.
Also, if you hold that the forward slid of the foot is beneficial, the layer of separation between the spike and the footbed in super spikes provided by the layer of cushion effectively serves to allow forward slide of the foot by compressing forward while the spikes stay gripped, enabling the sprinter to get the best of both worlds.
Great video. Just two questions.
I heard from another track coach on TH-cam, that the foot should land just a bit in front of the body to load the achilles tendon before the next step. Would landing directly underneath the center of mass prohibit that?
I also heard from another youtube track coach, that hamstring ruptures happen in the late swing phase, when the hamstring needs to contract under extension. Now you told us that the breaking force of the ground causes hamstring injuries. I am totally confused.
Hamstring strains occur late in the swing phase as the hamstring eccentrically contacts to stop the lower limb from continuing to swing forward.
@@tracktuary is correct. The mechanism described in this video (of sudden braking on ground contact) doesn't make sense.
@@jameshegeman5660 sorry about that
@@jameshegeman5660 I completely agree. It is just flat out wrong information.
would the ''spikeless spike'' be super beneficial to distance runner?
yes
Honestly there is a huge epidemic of distance runners wearing inappropriate spikes. You see 3k/5k runners wearing 1/4”ers on dry tracks. Just counterproductive. (If I were running those distances, I would either use flats or 1/8” needles; *maybe* 3/16” needles if it’s a particularly gravelly track.)
I tried a pair of the no spike spikes and I hated them
why?
@@TheWayToWinIt felt like my feet were slipping during my start and it messed me up. Its feels like doing blocks with tennis shoes.
Pourquoi on court moins vite sans pointes si elles sont si inutiles que ça ?
@@jackm727 I didn't mention the name of the spikes in the video because I'm not entirely fond of them. I believe they could be upgraded slightly to function more effectively
This is CRAZY, I was wanting to make a similar video to this for my channel bc its not understood enough but you've done an EXCELLENT job explaining it here!!🤓 Beat me to it, plus you can reach way more people than me😂
Thanks. That's just regular stuff that every professional coach knows.
What do you think about buying a pair of sprint spike and never screwing in the metal pieces?
It's good idea if you run long sprints outdoors
Can we get pinless spikes by just removing pins from our normal spike shoes or de we have to buy specially made pinless spikes
Wearing regular sprint spikes with the pins (spikes) removed is almost always a bad idea. Your feet will slip horribly, because the shoes weren't designed to be used in that manner. The spike receptacles generally have an annulus of smooth hard plastic which usually protrudes and provides very little friction.
Great video
thanks for watching!
How do pinless spikes compare to the maxfly?
we will see
The maxfly is undoubtedly better😭
@@Josiah_Vidzro Not better for your feet or healthy for you. Nike doesn't care about making shoes that allow your feet to move like they do naturally.
@@gmaxsfoodfitness3035 I agree but I is a small sacrifice for being competitive at all
how do you know he doesn't train with spikes? most sprinters train a lot in spikes also during off season. Warholm trains in spikes every week the whole year round
There is no chance imo that he didn't use spikes for several months and all of the sudden he puts them on. Very good question!
on that run he used spikes for the first time after month of training without, even the coach said so after the race
the coach said so? then fair, however, this video made it seem like a whole off season without spikes. one month without spikes isnt that much@@ontlametsemoyunda4941
He got injured and had to avoid wearing spikes for a while which is why he ran that 400m in flats. Is saw that video the other day and it specifically mentioned Tebogo wearing flats instead of spikes.
@@malkiqtigari3089 How is he going to use spikes if he's hurt and in recovery? He had to take it easy until he got better. Spikes would've increased injury risk.
That's interesting, I guess no point for me to wear spikes ever then really since I just sprint for fun and health at times and wanna make it as safe as possible.
That’s what I was thinking, except that I slip and fall on grass when starting in a 3-point stance if I don’t wear spikes.
What’s the name of a spikless spike
asics metasprint
Way To Win knows what’s up. Where did you guys learn all this sprinting black magic?
it's white magic
then why do middle distances runners also wear spikes (800m-1500m)? the acceleration phase has a very little importance.
I have the same question. Imagine a bicycle with spiked wheels. What would those spike change? You will go slower while working much harder.
I'm gonna be honest though every single person I know, including myself hates the pinless Asics metasprints and the only person to actually run fast in them is basically only Kiryu
You mean without wearing spikes , just by running sneakers , we can improve your top speed?
No, you need a hard plate for speed, so sneakers won't work. But if you remove the spikes from your spike shoes, then you can reach a slightly higher speed; beyond that, you will relieve excessive stress from your hamstrings. However, you will lose grip during acceleration. Therefore it's best use pinless spikes in the 400.
Is there no benefits to me training in spikes?
No animal runs with extended claws. Pinless spike shoes are faster and healthier.
@@TheWayToWin Thanks for the reply. I'm still torn about my spikes which I love, but I think I will begin to train speed in shoes more often.
@@swaggyp1320 Speed is about the force delivered into the ground and returned back; you need a hard plate and no spikes for that.
Bro got sponsored and decided to say that the spikes that practically every pro sprinter uses are a bad shoe
It's simply common sense: ride a bicycle equipped with spiked tires first, then switch to normal tires, and you'll immediately notice the difference. Similarly, wearing spiked shoes makes you expend more energy and run slower.
What's the relationship with a cheetah ?
Hopefully just friends
Erriyon knighton don't use carbonne shoes
good for him
I know he isn't the subject of the video, but given his 6.43 pb, what time do you think noah lyles could run at the olympics?
at least as fast as he wanted to run in Budapest
100m 9.75-9.85
200m 19.35-19.60
But a shoe shouldn’t propel more force than what’s put in. That makes it illegal and we will get fake times. We will think people are getting faster when they are using technology that gives more than what the athlete is putting in
the shoe doesn’t give extra force or add additional force to the force that the athlete initially is putting in. Its just returning the athletes rate of force more effectively so there’s less wasted force in the athletes initial force.
@@delpradojosiah Maybe not this. But brands have began making shoes that actually do that. I think one such shoe they use for long distance running. I think a female hurdler ran in it and broke the 110m record. The risk is that in time it may be mc come legal for the sprints. People may be ok with it because if the fast times and use improving technology to justify it. But real runners know any records ran in those should have an asterisk beside it. I just look ahead.
@@laughingbird i agree, i think when it comes to big races like the olympics all participants should wear the same standard spike shoe to see how much is really the athlete, not the shoe.
