Elitetrack: Sport Training & Conditioning

I’ve actually had similar thoughts but I am still debating whether this advantage outweighs the disadvantage of being in a poor / artificially created position for acceleration.

and what did you find Mike…a sweet spot ?

I’m really not sure what the answer is here. It’d be nice to be able to experiment with someone else’s athletes though :spin:.

Excellent thread men.  Keep dropping the knowledge bombs and I’ll keep collecting the pearls of wisdom on my hard “drive”

Thanks fellas!!

I’m trying to digest all I’ve just read, so bare with me if this strays or goes completely off line…

While not mechanical, are Ben’s and Flo-Jo’s batteries just bigger than anyone else’s?  A deeper ATP pool gained through incredible strength levels?  Maybe this alludes to Phoenix CNS protective mechanism or KT’s speed endurance qualities.

Can anyone please post video of textbook accel. technique (angles) I am playing around with dartfish and have nothing “perfect” to compare my footage to.

I don’t think so….maybe just better strength levels which allow them to push themselves upright quicker and move through acceleration faster.

I don’t think it works like that (increased strength ~ increased ATP).

I’m away from my office but will post something when I get back in early January. If I forget just remind me.

Great will do.

Mike and others opinion,

So going along with this thread, what would the goal be for a football player getting timed in the 40yd dash. Does he want to get off the line and get upright as fast as possible, or really try to accelerate as long as he can?

They should move through body angles progressively, having each step push their body in to a little more upright position. They should definitely not try to “stay down” or do the HSI drive phase.

So let it happen, rather than lean to one way or the other?

Yes. In fact, I tend to think this is the way it should happen no matter what the race…..make sure force application is directed through the long axis of the body and let each step push the body to a more upright position.

would this mimic what ur saying above mike, if u were running 60 meter races and u ran it the same as the 100? 
for example ur drive phase would be for 3/10 of the race supposedly in the 100, which would be 30 meters, so for 60 meters 3/10 would be 18 meters.  so for the first 18 meters u accelerate and let each stride take u more upright, when at 19 meters ur upright.

could this approach be taken or would it be junk?

another thing i seen before was that Flo-Jo had a 150 kg lunge.  would having 150 kg lunge strength in each leg mean that she could rapidly accelerate her thighs, (from her mach A position in her sprint cycle to the point in her stride where her thigh begins to come back up to the mach A position), faster than anyother lady?

a 150 kg lunge sounds pretty lethal for a lady.  Or is that a norm among elite women sprinters?
