sprinting is VERY effective at increasing the VO2Max. when training at or near your VO2Max you are working at maximal effort this will improve your VO2Max. the higher your VO2Max the more fat your body will oxodize after training. so during the sprints your body will utilize carbohydratres for energy. and for several hours after sprinting when GH levels are still elevated, the body will utilize fatty acids for energy.Originally Posted by ABLQ2
growth hormone has a very anticatabolic effect so it is protein sparing. so no worries about burning muscle with this type of exercise. you should see results in several weeks. this is a very good time to supplement with creatine as ATP is the primary energy source during the first 50m of a sprint.
don't be surprised if you puke doing this...lol
