No, not really. One of the best things you can do for your jumping is to jump maximally all the time when you play... you start to "expect" jumping maximally and becomes more or less 2nd nature. At least, I think so. Because I'm too lazy to do it.
We are not saying not to jump maximally, just pick and choose the times, and pay attention to where you are when you do, where you will land. Youre an idiot if you are playing a lot of basketball and dont acknowledge the risk of coming down on someones foot when jumping in GAME SITUATIONS, no matter how healthy and strong your ankles are, you come down on someones foot from a high enough level and its game over for you. Bye bye training gains that you worked so hard for, bye bye season, and sometimes this can cost you your spot on the team.
Test your ingenious theory out, go play 3-4 hours a day of competitive basketball, GO FUCKING NUTS jumping, as soon as you see a crowd under the rim, take off from outside the paint and just launch yourself into the lane. Dont worry about where you land because you have good structure and mobility of the ankles. When a shot goes up, JUMP MAXIMALLY STRAIGHT UP IN THE AIR, stand as close as possible to all the others standing in the lane when you do it, again, dont worry about where you land due to your advanced ankle structure/mobility. Come back to this thread in a month or so and report how it went.
Haha, sorry, but can't do. Heck, I look at the ground when I jump alone on the court, let alone in traffic. Hence I turn into a jumpshooter when I play ball, and I think that's a smart thing to do.
There are crazy people that penetrate a lot, jump a lot, get injured a lot, and then complain about their injuries.
