Really really good stuff. You are so generous. BTW,your vertical program is the cheapest I have ever seen on internet. But I bet it is also the most worthy one. You just such a generous guy. I really respect and appreciate it.
Every athlete is a different puzzle, so I can't really answer that. But I'm generally trying to get sprinters to get posture right, and beyond that think less and just compete
Addison Lomick You should think of powerful foot strike off a dorsiflex foot plant , forward mechanics and powerful relaxed arm .swing . ( These are the basic things to think about) There are secret things that really make you run faster but I don't wish to divulge them here now .
Some numbers might help people to get it. Like say your rate was 5 (whatever - strides /unit time) and the length was 7. Your overall output is 35. If you increase the rate to 6 while decreasing the length to 6, you come out ahead with 36. Then you increase the rate again to 7, but your length drops to 5, then you are back to 35, below your optimal 6x6. Just some numbers, but it demonstrates the point.
bro desperately need video on drill to improve sprinting techniques and how they affect your sprinting and ways to increase force production, thanks in advance.
@@JumpScience22 Well usian bolts coach told him to focus on maximizing ground contact (stride frequency) during the acceleration phase. So I guess during acceleration you do want to go ham on trying to hit the ground as much times as possible.
@Moneyxl00 I'm short at 5'10 and going for that frequency during the acceleration phase, has helped me that much more. Look at tyreek hill. 5'9 with insane stride frequency.
+prankspickup because of the difference in the time frame for producing force in the two movements, body type advantages/disadvantages, unilateral vs bilateral ability, and sprinting vs jumping experience
prankspickup because they have poor running form . I got a very slow kid to beat everyone at the club by just teaching him how to run properly. I saw he had potential from his jump
Good Morning and thanks for your two equation run analysis. I am your friendly, neighborhood Rocket Scientist and I appreciste that you are working on this 2 variable non-linear model. Do you have a video which would help me go from 9 to 7 minutes/mile for my 10k runs? Further, have you determined further dominant variables along with strength/endurance tips? I am enclosing a 75 degree day from Santa Barbara. Cheers.
This is from the wikipedia... "A resultant force applied over a longer time therefore produces a bigger change in linear momentum than the same force applied briefly: the change in momentum is equal to the product of the average force and duration. Conversely, a small force applied for a long time produces the same change in momentum-the same impulse-as a larger force applied briefly " .... what do you think about this? still confused...
+pavel Hykl It's all true. Force x time = impulse. But if we're talking about top speed, we don't need a larger change in momentum. We need to achieve a tiny vertical jump on each contact. The jump doesn't have to get higher for us to sprint faster. It needs to get quicker.
This is slightly off sprinting but still related to the stride rate/frequency debate - what do you think about the 180 cadence that is generally preferred for marathoners, due to which I notice many runners doing high cadence runs even at aerobic pace.I'm not very convinced with this whole idea of high cadence taking shorter steps.I feel cadence comes as a results of going fast and not other way around where high cadence is making you fast
I would agree. Improving force production / speed naturally increases rate and length. Intentionally being very long or very quick makes you slower. Someone can probably make an argument for it as a training tool, but it still wouldn't be the right way to run a race.
Why do whites making jumping high so complicated all you have to do is jump around a lot and you always in the weight room all you have to jump a lot and your vert would be much higher not trying to hate just spreading the truth
The fact that you or some other people can have success doing that does not mean everyone can. There's a lot of potential problems and limitations you can run into, and even if you do have success, strength training will still help you have further success. Personally, if I don't lift, I turn into a horrible athlete. Keep your "truth" to yourself.
+Jump Science you just don't know man if you just jump 25 a day and rest some days yours hops will automatically go up. But keep weightlift if you feel the need.

Awesome I've become a big fan of your info, can't wait to see it!
refreshing stuff great job mate
What should I be thinking about when sprinting
Every athlete is a different puzzle, so I can't really answer that. But I'm generally trying to get sprinters to get posture right, and beyond that think less and just compete

Angelos when will u say it

Then you increase the rate again to 7, but your length drops to 5, then you are back to 35, below your optimal 6x6. Just some numbers, but it demonstrates the point.
Yeah, I originally planned on using some theoretical numbers but then decided doing calculations would just confuse people and lose their attention.

Shorter strides with faster stride rate makes you quicker right even though you don't get the highest top speed?
It's about finding the right balance between stride length and rate, even during early acceleration

If producing vertical force makes you faster why do some people with over 40 inch jumps can't run mid 11 in 100

For real, I've seen dunkers who look weird when they run and are slow
can you explain also how to train to get better force production? Do i need more explosiveness or strength?
great videos btw

see speed science 7
Correct as far as for a given speed eg. 10m/s and given limb length/ hip height from the ground
I'm going to #7 now--How to improve force production. Thanks!!

I'm looking for speed science 7 did you put it out yet?
Nope
When will you post speed science 7? :-)
hopefully this week
or possibly not for a long time. very busy right now
jaj :-/
Is speed really 100% genetic??
darius140 the less genetically gifted you are the more important training adaptation becomes.
nice
You know as the president of Jump Science University I thought for sure I would get a better answer than NOPE
hoping to get it done this friday
