Denis,

Just some thoughts. In general, ROM is limited in these exercises. As

a specific exercise for sprinting, there is no forward motion,

limited swing phase, and in the jump march, even a pause at the

stance phase. In the low march, very little plantar flexion, knee and

hip extension is occurring. That one looks pretty much useless to me.

The high march looks better but is still limited. The jump march has

it's own problems but at least stretch shortening cycle seems to get

a good workout.

I've tried jumps on a high box as well, ie, high jump march, which

adds more hip and knee flexion to it. In any case I'd rather be doing

bounds, jumps and stuff on the grass.

Here's the link again for all to follow (under marches).

How did I do?

For sprinters, I would have to be sure that training that improved

starts and first phase performance was not at the expense of second and

third phase performance.
