Why do power movements tire me out so fast? And what are some good power movements/exercises too?

Say like wrestling someone or prowler. I LOVE that stuff but it gets me so winded after about 30 seconds or so and I feel dead afterwards. It's like anything that uses my torso and hips to generate force gets me so exhausted and I just can't catch my breath after 30 - 45 seconds. I love it, but I'm wondering why I cant last that long doing this stuff.

Because you are using the big muscles in your body which require a lot of oxygen to operate....

There are several energy systems that are at play here.
You have your quick stores within your cells which can be used immediately, no oxygen required. And then you have your energy system which consumes energy without the presence of oxygen. Because there is a higher demand for energy in such a short period of time, your body forgoes using oxygen to produce energy and produces it without it. The by-product is lactate and hydrogen ions (lactic acid). That leads to the burning feeling you get when you hit the sled and often deters the power output through out the movement. Often that's associated with fatigue. You become out of breath because the body needs time to catch up metabolically (buffering of hydrogen ions, converting lactate back into usable energy, normalizing your oxygen levels, and etc..)

Another interesting theory is calcium depletion within the cells of the muscles. It's literally "squeezed" out and the muscle can no longer relax and tense fluidly because of calcium's role in muscle contraction. That's the feeling you get when you're pushing harder and harder, yet the sled isn't moving any faster or your opponent seems to weigh 40 pounds heavier than usual.

Over time the body adapts and is much quicker to recovery after each bout. It has good carry over into endurance based activities such as running or basketball since lactic acid is being cleared out much more quickly, and the body is able to handle being in an oxygen depleted state much longer.

Deeper level detail to play off of marmel75's explanation.

I work out in the evenings, and afterward I feel too tired to do anything, even though I promise myself to get some work done on my laptop. It never fails - I'm too tired. It's especially squats that makes me tired I think - it is truly the killer exercise. It wipes out everything.

I'm talking power. Squats have the greatest effect on me the next day, but the most exhausted is stuff like prowlers, sprints, cleans, etc.

This is kinda common sense, you know.

More so than other people. That isn't common sense to me

You're asking why big, hard, heavy work tires you out faster? Maybe because it's big, hard and heavy?
