Strength, Power, Reactivity, & Speed Discussion / Re: Jumping Sessions

I heard of a study somewhere that found athletes got statistically significant potentiation gains by warming up with a weight vest that was equal to 2 or 3% of their body weight and that heavier weight vests did not help. Not that we are talking about potentiation, but training effect. Either way, I think that just adding a few more pounds than bodyweight can go a long way, especially because technique is not drastically altered.
Charlie Francis says not to let sprint sled training reduce your top speed by more than 10% and though jumping is more force/less technique oriented, I think it maybe good to spend time with lighter vests than typically advocated.
In the past I have usually done bounding with vests between 8 and 15lbs. I tend to only use them for endurance bounding type work, just because I leave the overload in single response activities such as depth jumps to the increased height of the box. I do think vests have helped me with the bounding in the past, I noticed good results coming off of vest-reliant cycles, but I haven't done anything like what I am about to start, which is about 20 max jumps in a weight vest outside my ordinary sessions each week. I'll probably keep the weight around 10lbs.
