Boxing - just making weight is difficult plus you gotta have a good STAMINA to last in a fight. Gotta have a good chin. In MMA you can slack when the fight is on the ground or during hugging - in Boxing you should remain upright. - if you get knocked down - you must stand immediately even if you're groggy. Imagine boxers banging each others head for 12 round.

In MMA, the fighters are guys rolling around like homosexuals.

I'd say American Football/NFL especially if you're playing the running back position.

WWE - if you can even call it a sport. So many lives taken already.

I haven't participated in actual combat, but MMA training kicked my butt pretty good. This coming from a guy who's been doing regular exercise/workout for 10 years before trying out MMA. Not to mention you could break a bone or two while training.
