What are your thoughts…
Should be a very very shallow slope.
I don’t like them because of the pounding on your lower extremeties and the knee problems it can cause.
You asked for thoughts!
There can be a lot of stress on the Achilles tendon. 400m stud is right also.
I think that Charlie also mentionned that it changes sprint mechanics negatively
if doing downhills the slope must be very slight.any major hills will leave the athlete landing way in front of the COG causing breaking and leading to extra pressure on the h/s.focus on running faster by improving aspects such as mechanics from blocks to accelleration to top speed technique
