how often should someone sprint?

Well sorry to disappoint Relentless but sprints are just anaerobic during sprinting glycogen in your muscles provides the energy, without oxygen and produces lactic acid in the process.

During your recovery time your aerobic system takes over. Your heart and lungs go into overdrive, bringing oxygen into your body to help break down the lactic acid, let your body recover, and get ready for your next sprint.

 

That's what he said...

 

Relentless said "sprints aren't just anerobic" then says afterwards "the aerobic energy system kicks in after the sprint" which is correct. So the actual sprint itself is completley Anaerobic......

 

I think he meant what you said above, just worded it wrong. :think

 

yeah, basically.

 

Sprinting may be better for amateur but im saying don't forget your aerobic systems, they still need to be on good levels- aerobic systems aids recovery from anaerobic bursts . Don't forget Aerobic people , understand that it still has an importance . hope this helps

 

Nothing is just anaerobic, even in the 6 or so seconds you're using your immediate anaerobic system there is still your aerobic system playing a very small part. Repeated sprints can give you a terrific aerobic workout, far better than a long slow jog.
