can 100m and 200m tines be predicted by strength

I know for a fact that it won't do anything for the 400m because you need great working aerobic and anerobic systems. While the 100/200 is almost strictly anerobic. Also I'm talking about runners who've been doing track for 2+ years.

TRUE!

red:

I am glad you asked the question but world class runners will agree with the previous poster.

Balance, Acceleration, Relaxation, "Classic Running Form," Neuromuscular performance, and many other things make up a good sprinter.

You are right about the 400 requiring some Aerobic power. I have stated many times on this forum that the 400 requires about 33% aerobic ability. (This depends on who is doing the testing, how fast you run, and your physical makeup.)

Sprinting is also a highly technical event. It's not as simple as just blasting down the track. The 100 and 200 do require some aerobic power, especially for training. Remember that the winner of the 100 is not always who accelerates the fastest, sometimes it's who slows down least ala Carl Lewis!

It does do something for the 400...

But when you have the majority of 400 runners these days at around 170 lbs ... Then being big and strong really doesn't play a factor...

The human body can't handle anything over 90 meters all out.. This is why the body types between 200 and 100 runners vary so much...

200 meter runners are really skinny for the most part..

It's because anything over 90 meters prohibits protein synthesis within the muscle fibers thus causing the muscles to become weaker and smaller due to the stress..

There is no point in running anything over 90 meters all out.. Because it causes too much lactic acid buildup in the human body thus making everything weaker and smaller..

So in reality why would you want to become a weaker and smaller human being?

My weight went from 210 to 232 lbs after i quit doing that stupid 400.. And i'm not even fat.. I'm trying to gain weight to get stronger in the gym.. I workout all the time..

Just goes to show you the 400 does nothing..

Can sprinters times be predicted by squat, deadlift, bench, and power clean max compared to body weight. I know it can't be exact because of to many variables, but could there be an estimate time. If someone could do this could they help me. My Bench is 1.25x my body weight, my squat is 2x my body weight, my deadlift is 2.5x my body weight, and my power clean is 1.25x my body weight.

See:

Squat levels can predict sprint performance....all the way to 10 meters. Improving squat strength from 100kg to 200kg can gain almost a full second in the first 10 meters. But that's the end of it. The upper limit comes at around 400-500 pounds because that's the point where increasing strength in the gym costs more in performance on the track (due to higher CNS load and longer recovery time) than it gains from strength performance.

There are other forms of strength training: heavy sleds, steep hills, plyos like drop and depth jumps. All of these improve performance for somewhat longer distance than squats.

Sprinting is about power.

Weight room numbers are about strength.

Power is not the same thing as strength. As an example, I can squat double my body weight. But I can only run 11.5 in the 100m. Because I lack the ability to translate my strength into power. I only lift 3x per month. If I lifted more, I could certainly get stronger, but it also probably wouldn't make me any more powerful. I am trying to get more powerful through my sprint training, plyos, sled pulls, etc.

Studies using soccer players are a bit misleading. They are taking somebody that is doing a full training program. In general somebody under that program who is more explosive and powerful probably also is stronger relative to body weight. It isn't a linear function, but it is in general terms. So then they do a study trying to correlate strength to explosiveness. There is some correlation of course, but that doesn't mean that increasing your raw strength relative to body weight will result in better sprinting speed, unless maybe you were doing no training at all, then started doing lots of heavy squats and deadlifts.

I know you need a good aerobic capacity for the sprints, and also you need to be able to turn that strength into power when you're sprinting. That's why I do a lot of plyometric exercises when I work out, plus I thought the power clean did a good job in doing that.

I can squat 290 in the Smith and deadlift 160 (non-Smith). 25.3 for 200. What does that say?

I think you mean anaerobic

No I meant aerobic so you don't die out. You obviously don't need to do long runs every day, but you should have a decent aerobic base

this is easy, each step is like a jump quarter squat, elite sprinters do what 40 steps in the 100m? so I would say your 20-rep single-leg-quarter-jump squat max is very correlatable to 100m speed.

I have timed almost every rep with a free lap timing system in the last few years and there is a very strong correlation between my squat strength and my first 10m. My best 10m times are all when my full squat is over certain threshold. My acceleration curve is also fairly consistent, meaning if I gain .02 in the first 10m I also gain .02 in the 10-20 and 20-30 split.

I have also used the trap bar deadlift at times though and there seems to be a low correlation between it and my 10m times for whatever reason. Strength gains in the trap bar also don't seem to transfer directly to my power clean either. The ratio between my powerclean and squat remains consistent, if my squat goes up so does my powerclean. That is not the case with the trap bar though.

Wtf is trap bar

If you are well drilled and regular plyo work, with those numbers id say you are around 10.9/8 ish

Has some nice correlation figures etc

It says you need to learn to deadlift, that is a scarily wide difference between squat and deadlift.

It is the bar that you can stand inside of, so that you can deadlift with your hands in a more comfortable position. You could have just googled it:

Uh that's exactly what coordination is. Running efficiently is a skill.

10.8? With a 25+ 200? Lol

10.8? With a 25+ 200? Lol

Such a scenario is possible for someone with little speed endurance. Naturally gifted sprinters can run 10.8 100m with little or no training.
