Sprint running: Pros and Cons
I'm not an expert runner, nor am I even close to being a competitive runner. I am a guy who did the 100m dash back in middleschool/highschool pretty decently. I think the fastest time I ever ran in the 100m dash was mid to high 11's and I averaged low 12's to high 11's. Once I hit 10.99, but I think it might've been a timing fluke or something. But hey, it "happened" and then I quit running in the end of my freshman year to focus more on TKD.
Sprint running and what it does for you:
From what I've experienced, I have always liked sprint running because it really gave me a great cardio workout. Not only that I could do it multiple times without killing myself of energy. Sprint running I think can help you as a martial artist over long distance as the kind of action you're doing is similar to what you do in a fight, you burst out with all your might for short spurts of speed, and this is true for sprint running.
I think it's also because I'm lazy and I don't like to run for long periods of time.
What it doesn't do for you:
It SSSSSSCREWS up your knees and ankles and spine like no other if you don't get proper instruction on how to run. A lot of people run flat-footed, stomping their feet into the ground flat. From what I have been taught (You can correct me if I'm wrong) was to run (this is for sprinting purposes) on the balls of your feet. I think from what I can tell, there are a lot of differing schools of thought on this. I see a lot of people who do the traditional heel to toe method and seem to do alright, but the faster people I see run on the balls of their feet... like ninjas. ;) But the people to run like lumbering, mouth-breathing sloths, they try this sport and usually tear up their parts.
Anyway, discuss away.
