One-leg jumping fatigue

[teenathlete3030]

I've always been a one-leg leaper, but since I've put on some strength my running two-leg jump has gone up. During practice people will go up and grab rim for the heck of it. Usually I go up with two legs because I'm too tired to go off one. At the end of practice I might go and try for a few dunks (off one leg). I can get a lot higher but after a couple jumps my leg feels fatigued and I can't jump as high anymore. What's going on? And what can I do to rebuild that tolerance for one-leg jumping? Maybe less going off two legs and more off one? I'll need it for high jumping big time.

You are most likely to lose some explosiveness due to added weight and different style training. You might want to incorporate a bit of plyometric box jumps to keep it up if you want. Your fatigue tells me that during the said jumps you are using the fast twitch muscles that can generate a lot of power for a short period of time but fatigue quickly.

Switch legs. Don't let one become dominant. That's called an imbalance.
