Re: Is warming up THAT important?
cramping can be caused by being unfit, your lactate threshold is small, stretching probably won't help that, by the way the only time I see atheltic animals (horses, dogs cats antelope etc) stretch is when they first get up after sleeping or resting. they don't seem to suffer a problem despite being able to run and bounce at high speeds.
second you need to take up some kind of aerobic exercise regularly, sporatic exercise won't cut it. biking, walking running or some other sport that requires regular partcipation and steady action for aerobic workouts including some aneraboic, by the way basketball is considered a anaerobic exercise (without oxygen) and that is why lactate builds up quickly if you are unfit. causing cramping. O2 debt as it were,
and it is in your calves because calves have fast twitch muscles in abundance (meaning using sugar without oxygen) and the calves carry most of the weight of stop and go exercise. aerobic exercise will help by making the heart the blood vessels more effecient and more able to provide oxygen in enough supply to take care of your lactate problem being able to deliever O2 fast enough is the key, to that problem.
