Strength, Power, Reactivity, & Speed Discussion / Re: My calves.
« on: November 07, 2010, 06:12:13 pm »Well theoretically your calves don't do much in terms of jumping. If you isolate them and jump only by ankle extension you won't get very high. Good plantar flexion ankle ROM is a great way to get more out of them I suppose.
if you isolate them from a static position and try to maximally pushoff and get airborn, then yes, you are right.. but that's not how the calfs work in explosive movement so.. if you want to see the calfs contribution, look at completely stiff leg ankle hops, which in experienced jumpers can yield some very impressive heights.. pogos utilize more quad, with the degree of knee bend, but you can get some serious bounce going 100% legs locked.
that analogy of 'jump only with ankle extension' is bad though, have you ever seen someone jump ONLY through knee extension, or ONLY through hip extension ? first of all it's impossible, but secondly, it's just now how the body works.. so to diminish the role of the calfs by saying "look at how they perform in isolation" is really off base.

However, I have a feeling that once they get "loaded" at high speeds/high forces they contribute much more than you'd think.
when you squat 1RM, there's no calf of course, but consider the amount of force you can apply to the bar in a squat, then consider how much force you can apply to the bar in a calf raise.. even though the range of motion is much smaller, improving maximal strength abilities in any movement will also improve the capability you have to increase explosive strength in that movement..
for example, eddie jumps way higher than me, and most people on the planet (during his peak), one thing he could do very easily, is calf raise a ton of weight.. he could easily calf raise 225 lb on the bar for 20 reps the first time he ever tried.. 225 lb calf raises for me, i'd be lucky to get a few strict ones.. eddie could strict calf raise 225 x 20 at 148 lb.
