# CT during acceleration verse max velocity

Recently i read over some research which showed during early
acceleration approx 67% of the time is spent on the ground whilst at max velocity the figure drops significantly to 40-45%.

The differences in CT during acceleration and max velocity shows the importance of maximal velocity runs in training.

Often Max velocity is inhibited by excessive speed endurance & short acceleration work since ground contact time is significanlty longer.

1. Should the volume of SE & short acceleration be decreased and substitued with Max velocity runs?

Commments?

Shamer,
But the thing is if this was done what would be accomplished?
Because reguardless we can only hold max velocity for around 2 seconds or 20 meters. But correct me if i am wrong but i think i see where your gong with this. After all elements are in place would it be more benifical to spend more time on max velocity runs rather than short accel runs and or speed endurance. So instead of going form aceel work to max velocity work to speed endurance. Maybee going form accel work to speed endurance to max velocity work but still focusing on speed endurance.

I dunno am i not understanding what you are saying?

Surely the idea is to get the balance right between all three componants ?
whats the point of just having fantastic top speed if you canâ€™t use it to good effect with SE or if it takes you an eon to accelarate up to it ?

This must probably be dictated by the athlete in question. The coach must find out in what areas the athlete would benefit the most.

Your right top velocity only for last approx 2 sec, however a athlete with a higher top velocity will reach max velocity later therefore decelerate over a shorter distance.

Higher top velocity means a Longer acceleration phase and a reduced deceleration towards the end of race.

Imagine a 100m race between Micheal Johnson and Carl Lewis, over the final 40m Carl would pull away from M.J not because of higher SE qualites but as a result of higher max velocity and a shorter deceleration phase.

I agree you need a balance between the components however traditional periodisation neglects the development of max velocity during GPP and Precomp.

In terms of having very good max velocity and poor acceleration theoretically its not possible, max velocity is a function of a efficent acceleration phase.

Acceleration work from 0-40 wont inhibit max velocity however high volumes of 0-20 may have deleterious effects on max speed.
