I am interested in hearing the thoughts of some other coaches. I’ve had this discussion with several top track coaches and many performance coaches I respect but still find both their opinions and thought proces vary greatly.
When it comes to using sleds for pure acceleration, how much is too much? Is it 10% of BW or no more than 10% drop-off?
I’m not trying to bait anyone so I will let you know that I regularly use very heavy loads of 50%BW to more than 100% occassionally. There are a lot of caveats that go with this, but the basic point is that there are compelling arguements of why it may be good to add more load. There is very little to refute it other than a “rule” passed down by coaches to athletes. You can read all my thoughts here. ArtofCoachingSpeed
Note, I am talking about pure acceleration. Maybe 1-3 steps for most team sport athletes and no more than 8 steps for most track.
I thoroughly believe many performance coaches mess this up with too much load at times and cross a bound from acceleration work into strength or conditioning. Still, when coaches well, I have found great success using very heavy sled loads as a technical tool, a training tool, and for potentiation.
What do you think and why?
