What is a the best way to start a 4 mile run – fast or slow?
I’ve had the best luck with an intervalic aproach.Starting slow after a warm up and strtch,then a brief sprint in intervals.The logic behind this lies in the fuels used for both types of activity(aerobic and anaerobic) and the physiological (or biological) processes that take place.During aerobic activity your body mainly uses fat converted to glucose through either ketosis or gluconeogenisis. Anaerobic actvity mainly uses glycogen(stored carbohydrates) for fuel.This will eventually cause a lactic acid build up in the muscles.The slower pace after will help these acid levels disipate and the body buffer these acids to remake fuels like ATP(adenosine triphosphate) and glucose.The Krebs Cycle is involved to some degree here as well. Your nubers are pretty good right now.My suggestions would be the careful choice of your day before pre run carb up.Of course long chain carbs help most but the addition of fructose(fruit sugar) will be better for replacing and storing liver glycogen(long ter
