Is 400 meter hurdles anaerobic or aerobic?

Answer 1

the 400m is an almost entirely anaerobic race if run competitively. This is because the body cannot adequately supply energy through the oxidative system alone. Thus the body reverts to the ATP-PcR and fast glycogen systems to produce energy more rapidly. Both of these processes produce usable energy without oxygen, thus they are anaerobic.

Answer 2

its anaerobic as no oxygen is needed

Answer 3

aerobic

Answer 4

anarobic
