Its used a lot to up the speed of NFL players isnt it? It would help my start a lot if i increased it and my start is oine of my majjor issues atm along with over 200m stamina.
It’s just a general test of explosiveness. It’s good to test speed/power and will help your sprinting speed, but I don’t think a sprinter should go out of his way to improve.
Your VJ should improve as your times get quicker, unless it was just technique making you faster.
The muscles that make you sprint fast are the same as used in the vertical jump.

Leg muscles?
this is a dangerous statement. The leg muscles are involved in both activities but different percentages of diffierent muslces are used for each one.
The vertical jump uses a higher percentage of the quads, running uses more hammies. If your entire get leg gets stronger than both will improve, but at different rates.
The important thing with improving your sprint time is not over dosing on a specific strength or plyo phase and not always mixing them.
Spend a certain amount of time on strenght, then plyo then both, then start again. The key is how long your phases are, you need the perfect phase for you.

Of course it’s a different statement, and you’re right VJ=A-chain and sprinting=P-chain. I guess I phrased that poorly.

This article talks about using sprinting to improve your vertical jump. You may want to check it out chanchu
Im more bothered about using the vertical jump to improve my sprinting speed, im not really bothered about my VJ tbh as long as it gives me a good explosive start and i get 11.something i couldnt care less if it was 12 inches or 40 inches, it would be cool to be able to slam dunk a basketball though

Improving your box squats or pause squats would probably be a better measurse of power off the line than vertical jump.
Why are you squatting on RE upper day?
My Upper Body was too tired and im trying to merge it all together this week cause im finished now, im resting for the tournament. Vertical Jump would be better to measure my power off the line and my stride length improvement though.
Walking lunges and pause squats will help run faster you more than jumping squats, and atg squats.
MY theory as to why pause/box squats are more beneficial for power off the line is that they both start from a dead stop, whereas in the vertical jump there is an eccentric portion.
the start isnt just getting off the blocks, its the transition into the upright tiop-speed phase and tht involves eccentric movements like in plometrics, i suppose pause box squats would be good for the actual first kick off the blocks though.
…The best measure of power out the blocks would be actually measuring coming out of the blocks!

Yeah, I meant for the kick off the blocks, I’m not sure what would be good for the whole drive phase.

…Why do you have be so practical? hehe. I think we’re discussing what’s a good indicator lift for speed out of the blocks. Of course actually doing the thing will tell you exactly where you are.
Not at all.
If sprinters only sprinted, or came out of blocks or practiced the exact activity, the 100M’s would still be at the 10.3 to 10.5 second range.
I’m Putting emphasis on building up physical maturity quickly, and physical power buildup and delivery.
Build the body, build the power and build the core first - then make it specific to speed.
The VJ is an excellent display of explosive power.
It is possible to go from a 27" to 35" vertical jump, or 215 to 285 power clean much faster than going from 12.0 to 11.0 on the 100M.
You will develop VJ height at a much FASTER rate than sprint speed, I don’t think anyone will debate that.
Our original poster who posted a 27" vertical jump, with 3 to 6 months of vertical and power training - 15 to 20 a day minutes 3 times a week, even if he fails to make 35" - I betcha he hits at least 32"…
Many have noted, that even without specific sprint training, if the vertical improves, there is usually improvement in the 40 yard dash or 100M.
It was mostly football players, high school and college who note that when the VJ and power clean improve - without ever sprinting, they notice the 40 yard time dropping.
Some of it is simply “confidence base”, some of it is your just working with more power.
Anyone who has improved from a 25" to 35" vertical or 27" to 32" vertical is harnessing more explosiveness.
Remember, the vertical is consisting of:
- Building up enough power before you even leap
- Displaying it through explosive form
Most of the guys wasting all this time, don’t have enough power to display.
My idea of going on ahead and building up vj and power clean in sprinter, was to learn how to build up more power ( charge ). You can use it for whatever you want.
So your wasting all this time running at a low power level, when its all going to change when you harness more power.
Why spend all the time running, when your form is going to change somewhat when your working with more power?
Remember most changes in sprint times from Jesse Owens in 1936 to today are not evolutionary at all, but rather technical.
Training techniques, psychology, weights, overspeed training, diet, etc are all different today from the past 50 years.
Very good info.
Thur Sprint Work
-300m fast jog followed by 100m sprint x 4 (no rest)
-60 Second 80% run, 60 second walk x 4
- 100m sprint followed by 100m walk x 2.
-1 Lap Cool Down
I can sprint a 100m full out now and have quite a lot of energy left to spare, a few weeks ago when i had just come back from injury i couldnt even manage 100m.
Congratulations on the recovery.
thanks i dont feel like ive reached the speed i was once at but i feel im close and will hopefully exzceed the 12.2 speed i was at by a fair bit for when the season starts in 5 months.
masterhaichanchu,
Just for your confidence - there have been guys who have improved from 12.2’s to 11.4’s or 11.5’s in the next year.
Actually in just looking, there are some who have went from 11.0’s to 10.2’s in the next year. So alot is possible. You might even be able to get to 11.0’s if you do it right.
