This was a good watch - interesting to hear your thoughts and feedback. You stated there is lot to be added in regards to context (technical ques and timing of the year etc will answer a lot of those queires ), so happy to fill you however you guys are both clearly very knowledgeable and respectful, not to forget very complimentary. two thumbs up from me. awesome stuff
Watching footage of Harry competing for GB right back as a junior in 2006, and how excited all the British commentators were on BBC, and during his recovery with the spine brace after his injury in 2007, every time he appeared then (and ever since) all of the commentators couldn't speak higher of him, and what a sound lad he is. The Irish athletics commentators on RTÉ coverage spoke equally as highly of you Harry FYI. Great to see with one single comment how justified they all were! Keep up the good work Harry!
As a sprinter the place I have seen sleds used effectively is almost as a cue for sprinters to push hard out of the blocks. Often younger athletes want to just stand up and increase turn over, but the sled forces athletes to drive for longer. The athlete can then have felt the sensation of the push out of the blocks, and become comfortable staying down and driving.
I had an issue with the presented perspective of sled running too. From my evidence in coaching the utility for both coordination (technique) and strengthening essential muscles is HUGE.
One thing that comes to mind which I think is a huge benefit and hard to back up or debunk by evidence is injuries. As the most specific work for sprinting is sprinting but doing that year round with high velocities does put the tissues at very high stress. Thus, using sleds to decrease the velo while having max intent, drive and so on you can really work on quite a specific mom event pattern while perhaps decreasing the risk of injuries. This cannot be scientifically studied with good quality because its not practical for sprinters to have only sprints with sleds in the training. Like Ben mentioned I think it creates a good learning environment for especially the start.
Commenting on a guy like Joe Kovacs who squats 320kg for 10 and does giant-swings on a gymnastics bar, while being a world champion shot-putter with a PB of 22.91m, could be a pretty good idea for a video!
agree with most stuff except at 20:30 about lower center of mass being better for sprinting. There's studies on this specifically showing higher center of mass and narrower hips is ideal for sprinting (a higher center of mass falls faster forward). I guess maybe you mean specifically "center of mass of muscle development".
You guys should do more stuff about heavy weight training in speed training, something that really lacking in available information! Great info as always though, subscribed!
I'd be interested in a vid on how weightlifting technique has changed since the "golden age" of the 80s and early 90s. What was better, what was worse, etc. I've been looking forward to the Nicu Vlad analysis (after the Pliesnoi one 😅) for this reason. Even a reaction video to one of the old competitions like the 1987 Worlds 110+ battle between Krastev, Kurlovich, and Taranenko. There were a lot of great technicians like Vlad, Syrtsov, Orazdurdyýew, and so on who would still stand out in today's competitions.
Greg Nuckols has an article on strongerbyscience called "Trap Bar Deadlifts are Underrated" that' argues against the "it's more of a squat" position. I wonder what ye're thoughts are?
Whenever people do weighted sprints or plyometrics, they always seem to justify it through some kind of bro-science. "If I can run fast while weighted, I can run faster when I shift that weight, it's science bro" I'm not saying that it doesn't make some kind of logical sense, but science, results and performance don't really have any regard for if something makes logical sense, only that it does or doesn't work. the results/performance say, in general, it doesn't work🤷🏼♂️
Another quality reacts video: Would you do another Toshiki one? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YpDnYJJMs0s.html&ab_channel=WeightliftingNewsAgent
Great analysis of 100m results at the end there. I'd sum up weighted sled vs overspeed training by saying that sledwork seems to pattern you to move slower. Over speed gets the limbs used to moving faster. Get the strength requirements done in the gym, then use plyos to move at maximum velocities. That will always be unweighted, or even assisted (band jumps, assisted sprint etc). A final caveat is that overspeed becomes much less useful if the assistance breaks the form. I think a paper pointed to no more than a few % decline on sprints.
I wouldn't call that naturally unattainable. He's plenty jacked, but he's an athlete and training his whole life. And being an elite level sprinter, he would have to be fast twich dominant trough the selection of his sport. I can't say that he's all clean, but he would most likely have an insane physique regardless. (2 cents, who the hell cares)
@@aduantas that's a good point. I wasn't aware of that. However, I never tried to protect his natty status, lol. I was just saying some people are just yuge. Some things even make people look even more jqcked. Such as, very round muscle bellies (which this guy has). I bet he would look freaky naturally, too.
Great insight guys. As a S&C coach and sprints coach I dont agree with your stance on research saying that weighted sled sprints dont make you faster. I know some of the research critiques the sports specificicty because of the load used changing the way the movement looks. However, there is also research showing that the loads (heavy to very heavy loads) that change the way the action looks impoves acceleration KPIs (JB Morins work).
Hi, thanks for the breakdown and analysis, super interesting stuff. I had a couple questions, one was regarding the first 20m of a sprint "getting up to a requisite speed" would that sort of training be beneficial to olympic weightlifters who don't have access to gyms, and what could that look like? The second question is along the same line and has to do with complexes. You talk about complexes and post potentiation activation with squats-jumps. Could the same idea be applied to sprints? for example doing a 15-20m sprint with a sled and immediately following it up with an unweighted sprint.
If you're looking for oly transfer, you'd be better off doing some plyo jumps before doing your movements. Atg posts a bunch of out of season training vids if you wanted to give them a look. Sprinting would help, but it's effort to set up and track. Dunno if it's worth bothering with if you're not looking to improve sprinting times on the side of your Oly numbers. But I'd imagine it would work if you did 15 mins sprinting, break, gym stuff, etc
In my training when pulling a sled or with resistance from the coach we would then do a repetition without with that idea in mind (post potential activation). The sprint without the weight you feel faster and maybe more relaxed, but this could be due to the positions the sled puts you in, I remember when on the first run without resistance I would stumble or nearly fall over when starting due to my body thinking I will have to push harder as previously there was a weight behind, I think this is due to wave summation in the motor units. Training over a period of time may help this but they said studies show they don't but the reasons sled pulls are still incorporated in sprint training could be due to helping the runner get into the right angles for effective acceleration.
I'd have to disagree with the connotations of being "too top-heavy." You have to delve into the topic of the kinetic chain and how it relates to the use of myofascial slings. In physics, energy is transferred and for energy to be transferred efficiently we must have a unit to absorb the energy adequately. With the kinetic chain, energy is transferred through the entire body from the ground up. Not leg to leg. For a sprinter, massive force is transferred through the leg to the upper body. Thus, we need adequate muscular to compensate for the effective transfer of locomotion, otherwise, there are energy leaks. Additionally, the technique of using the myofascial sling (upper body) to create locomotion is huge with sprinting, running, and throwing effectively. Essentially, we are throwing our bodies forward with the use of our entire body and traction with the ground. In sum, we do need large powerful legs as well as large powerful torsos to create locomotion. Maybe he can avoid curls and isolation exercises for growth lol unless it's to help imbalances.
Nice video. Here is a comment I will add as a sprint coach (commenting on 25:00 and onwards) The comment on top speed is incorrect. Velocity achieved is the highest correlate with 100m racing performance. Usain Bolt didn't just beat his competitors by holding max velocity for more distance (it's very true he had much less deceleration distance than the other athletes in his WR race). More importantly, it was his great acceleration (Amax) and max velocity that killed everybody in the race. Acceleration is defined as change in velocity divided by time. Since he got to a much higher velocity (12.1-12.3m/s) and got there quickly, it was no doubt he would break the world record. Sleds develop the important technical ability to orient propulsive impulse forward. There might not be significant neuromuscular capacity changes but every sprinter in the world has to use resisted sprint work both to develop technique and to run fast.
Disagree on T-B DL comments lads. If we're talking relative loading, you can put more weight on the T-B DL and get the athlete used to lifting heavier loads with less room for form breakdown and injury. Loads the posterior chain but less ROM on hamstrings than conventional deadlift so potentially if aware of hamstring load with sprinting sessions and hams specific work in other areas, Like RDL, or ham curls
Who’s science though? People who just say trust the “science” don’t understand what they are saying. For instance there are multiple theories on the creation of the universe so which one would you trust? Science is not set in stone and contrary to what people believe, we still know very little in regards the human body and muscles
Is their evidence that his weight lifting program has progressed his sprinting? By that I mean more muscle = more explosive/faster on the track. Or is his current program more for the social media be benefits. Like the guy is carrying a lot of muscle/weight in his upper body
We used to do sled/parachute sprints with a tear away which made me feel like I had a rocket shoved up my ass. Because you got both the pushing harder and the movement with just your body it was supposed to be better, idk if that's true in the research though.
So do the weighted sprints and/or sled pushes potentially help acceleration just not maintaining top speed? Currently, I want to have faster acceleration for sports but am not as worried about top speed. Do you guys know if the research suggests this helps with acceleration?
Many studies out there showing HRS decreases acceleration times. Haven’t seen one that says it makes you slower. If you have have such study please provide as I would like to give it a read.
Great vid. Can you consider looking at Hollywood brown's training videos he's an NFL wide receiver but has alot of training videos on RU-vid if you search Hollywood brown training. Would be interesting
Great video! I'd love to know if you had any analysis or commentary on cricket (fast bowling) and what sort of training might be appropriate for the sport. Compared to other sports, there's so little emphasis given to the physical aspect, and I feel like if there's anyone who could talk about it, it would be you.
I suspect the key for fast bowling is flexibility and shoulder tendon strength... the power comes from the catapult effect and technique. I've long been fascinated by this.
@@squirrelpatrick3670 Right! And it is one of those things that we cricketers (at least us amateurs) don't focus on developing. And truth be told, I don't quite know how to develop it. I also see that the best bowlers in the world can plant their front foot and go over the top of it like a trebuchet. I guess that's a leg strength and mobility thing. But for me I just cannot being to think how to get into that final position where I am actually able to go over that front leg (planted) while the shoulder/arm is still behind me. That slingshot is surely where the pace comes from, but god is it a hard and specialised position to get into!
Great video as always. Was wondering if you lads would be interested in looking at triathletes and their training. Could be an interesting video to talk about how the three sports affect their body and training.
@28 min, you are incorrect. Usain 30m split 08/09 world records 3.78/ 3.78- faster than anyone else in race and anyone in history. Go back to 20m he even has the fast split @ 20m. Vector calculation, average velocity 11.1 ms/ or 39.96k/hr 20-30m. Also incorrect that top 100 sprinters in the world have equivalent max speed. Less than 5 can hit top speed of ( 12ms) . Your thinking is outdated on the topic.
I agree if you look at 10m split data the fastest sprinters are accelerating at a high rate from the 10-20 split on. There are people who can run fast in the first 10m but there rate of acceleration is already off pace on the 20-30m split. Thus they will be covering less ground and will hit top speed earlier in the race. The time it takes to hit top speed will generally be about the same regardless of the level of an athlete. The faster athlete will just cover a lot more distance in that time. If Usain Bolt hits his top speed at 6.3 seconds in at 60m his average velocity will be the highest on the 60-70 split (.81 in his world record). He has less distance he needs to maintain his top speed for. Another sprinter who is at 55m at 6.3 seconds into the run have more distance to run while decelerating and will de decelerating from a lower top speed. I think Dwain Chambers (1997)and Usain Bolt (2017) are the only people to lose at a major maps with the fastest 10m split in a race. Usain Bolt because his reaction time and first 10m was so poor in that race and Dwain Chambers is the exception of a sprinter who couldn't maintain his high speed late into a race.
Bolt had a measured max top speed of 12.24m/s in Berlin '09 (at 65m), whereas the top speed of the second best athlete in a study on WC 100m winners&finalists '07-11 was Tyson Gay in '07 with 11.83m/s, a difference of some 3.5%. This is not an insignificant difference in max speed. Bolt did maintain his top speed very well (coming in at 12.04m/s at 80-100m, a drop of less than 2%), but I am curious to know who else could hit 12m/s? (source: Jiseon Ryu. Sprinting speed of elite sprinters at the world championships, presented at 30th Annual Conference of Biomechanics in Sports - Melbourne 2012)
If 280kg doesn't fatigue you on the trap bar deadlift, that just means you can load the bar further until it is challenging. That is a good thing. It means when loaded to a challenging weight, you are working more muscle groups fully than with a conventional deadlift which will probably be limited by your back strength.
12:21 “we don’t have the context...” 👏🏽👏🏽👏🏽 Thank you for acknowledging that! So many people comment on social media posts about athletes training when they’re usually just following the program, we don’t know where in the season they are, and we have zero context to exercise selection Great video 🤙🏽
Arm swing starts at the shoulders, upper back muscles for stability, chest for arm swing, biceps and triceps to help arms not gong straight and flopping
First time I've ever seen this guy, and he is certainly on PED's, its kinda shameful how everyone just condones blatant cheating now, like the fact any of these guys in the ufc that have FUCKING GYNO, can still wrestle, is disgusting to me
