I used to suffer generating so much force I'd get imbalanced at the ankles, losing speed in the process, dissipate. Then I increased the width of my foot strike, solved the problem, but has affected the ligaments in my right knee
You can never generate too much force. What it sounds like is your active stifness is pretty poor and your hips are externally rotated from alot if lifting. Look into hip into rotation and work on your elasticity
@@justjumari U can generate too much force as in, too much for the angle ur ankles r in when ur foot strikes the ground, causing an imbalance, too much force for the insufficient ankle stiffness... easily fixed by increasing stride width. Worked for me. Probably wont b the solution for some1 else
What does it mean ankle stiffness? While performing a negative foot speed, you have to stiffen your ankle squeezing calves and peroneus muscles before the landing phase?
How your ankle locks up in the amortization phase of the SSC. If it can withstand the forces being put on it, then it is a stiff ankle relative to the goal of course
Ummm the GCTs of elite sprinters are not .1-.2sec lol that's like a 1 foot speed jumper, elite sprinters are at like .07-.08ish. .1 would be a good college sprinter or so.
@@justjumari dude are you kidding me 😂. .07 compared to .1 is gonna be the difference between 1st and last in a race unless some dude has an unreal stride length. Even Bolt was .08
@@Messup7654 you just further proved my point lol. 30ms PER step x 43 steps per 100m = 1.29sec difference (potentially). That’s a big difference. Obviously, some of it can be made up during the accel phase before top speed is reached + other factors like stride length so it’ll end up being half a second or less between first and last. 2020 Tokyo: 1. Jacobs: 9.8 2. Su 9.98. Milliseconds matter in elite sprinting
this guy has to understand that more horizontal force/impulse makes you faster. It should be obvious that you need force in the direction you wanna go wich is horizontal. But for some reason people believe anything in the web instead of using their brain.
When did I ever say that wasn’t true lol. I just picked 3-4 things that made him faster, there is a whole system and hundreds of things that all athletes must posses to increase their speed or run sub 10. Idk how I said horizontal power isn’t important
@@justjumari impulse is the integral of force over time (Foce x time) [Ns]. Force has magnitude and direction so does impulse. Impulse is what makes an object change it's speed (accelerate/decelerate it). In running the only goal is to maximize horizontal impulse. It's really the only goal. nothing else matters.
you made a misstake. Vertical force is not the foundation of switching in the air. The Weyand study got very misinterpreted. Vertical force is not the cause for speed. I discussed this many times in many platforms. "Net horizontal impulse is the only cause of change in velocity! Vertical impulse is just a necessary evil"
Bet horizontal impulse is important, just not gonna be understandable to the average person who hasn’t read a lick of a book or research paper. Gotta speak at your audience level my friend !
@@justjumari I haven't said that you have generally very good content. Especially your advice for the need to compete and measure. I don't want to be disrespectful. I just freak out when people blindly believe studies and get on the wrong track
Vertical is not as important as you make it seem, a guy with a 45 inch vertical is probably never going to become a world class sprinter even with explosive muscles because you need to put force backward and forward for sprinting. It's true that vertical force is a part of it but that's not the reason Bromell is so fast
@@justjumari you're acting like Bolt is more "powerful" and takes less steps because of it as if he isn't one of the most genetically gifted athletes to live all while being 196cm tall, and you're comparing him to Su who's 24cm shorter than him and relies on fast turnover and a quick block start. He is the polar opposite of Bolt. Does stride length mean power now?
It's sad to see young coach's who don't have enough experience and haven't produce any thing try and try to tell people what it takes to run fast. The Europeans did every study.

Great quote, “Never try to improve the form without the structure.” Similar to the quote, “Form follows function.” That is from an example engineer.

Amazing video, gotta fight against the current of people who thing heavy lifts are the only thing needed for speed 💯
Yea I think people just don’t understand proper balance between both!
Weight room is a tool not a key!
@@nationradicalit is a key for speed it’s apart of the puzzle

Weights are a tool that allows you to grow specific strengths faster than bodyweight only.

From LSU ! I didn’t have the clip I wanted to use yet so I wasn’t sure if I was gonna use that race for the clip so I didn’t name anyone. Sorry
where can i find those studys?
what is your type of energy transfer? lol
Does anyone know where he is today?
How much weight do you prefer for the med ball
10-20lbs for optimal power

Ankle and foot STRENGTH. Vertical forces approach 3 to 4x bodyweight. To increase this strength progressive overload is required ( weighted training )
What do you mean by ankle stiffness? Upper or lower joint? Do you mean decreased movement in joint?
I wouldn’t split it through upper or lower. Look at it as GCT. And how rigid your foot is when it hits the ground
@@justjumari what is GCT? Sorry for my english.
@@joeweider4896 ground contact time, like how fast your foot hits the ground and puts force back down
@@FunkyFraank is it influenced by Achilles lenght maybe?
@@joeweider4896 yes Achilles length but also tendon stiffness and elasticity.
What’s the in. And out drill

When does height have anything to do with power ?
