During a run when should a runner start breathing harder and take in more oxygen, at the start or when tired?

Question

Should a running start breathing as much as they can at the start or when getting tired and needs more oxygen? Will taking in more oxygen at the beginning, help later on during the run?

Answer 1

relax and breath through your nose and out your mouth, maintain your form and keep your head up, when you drop your head your form is gone and you will make it harder.  if you start breathing through your mouth you need to train harder, cause your almost out of gas

Answer 2

u shouldnt try to breath hard at any point during ur run, it makes u light headed and nausious and dizzy if u breath 2 hard.  By breathing slow in and out  ur body will get enough oxygen.  Good luck with running!!

Answer 3

you need to let your body breathe at a natural rate. you don't really want to ever start breathing hard because you want to be at the point where you can keep your breathing relaxed while still maintaining a high level of physical exertion. basically when your body makes you feel the need to breathe hard you should start but you should still try to regulate it to some degree.

~(RE: Spell Bound) - don't breathe in your nose and out your mouth, even though a lot of people say this they are people with little experience, or knowledge. Breathe through your mouth entirely because this will get the most oxygen to your body in the shortest time. it doesn't make sense to say "when you start breathing in your mouth you need to train harder" because I ran a sub-4:20 mile and was breathing through my mouth the whole way.

Answer 4

You should try to maintain a steady breathing rate from beginning to end. Also maintain a steady pace.

Answer 5

Start slow go fast it makes you consistent and you can keep your oxygen stored!!!!!!!!!!
