The most fit of MMA fighters would be able to box 12 rounds imo, whereas boxers would tire significantly in an MMA fight.
Well you're contradicting yourself there because the anaerobic body would find it just as hard and vise-versa but anywho...
I've trained and sparred in boxing on/off since high school but have never competed due to a bunch of factors that I wont get into.
I last year started trading my boxing services (sparring) for grappling so I came to appreciate the hard work that also goes into the grappling side of it. I would say that the thing which wore me out MOST was the short extreme bursts of energy (anaerobic as others mentioned). Different sport so you're last question is actually your answer - "Is it simply due to the different fighting style"
I should have clarified my statement. MMA can be largely anaerobic, however Most MMA fighters are aerobically fit, where as Boxers are not anaerobically fit , because their sport doesnt require them to be ( generally speaking )... If you compare the two, the aerobic source is the least powerful, and cannot produce enough ATP per second to allow performance of maximal intensity.. But it can supply a virtually limitless supply of energy over a long period of time, which is why Boxers can fight 12 rounds without totally gassing.
So when the OP asks if Boxers have better Cardio, IMO no they dont. They may have slightly better aerobic cardio specific to their sport, but Conversely a well conditioned MMA athlete will be both aerobically and anaerobically fit.
