After the first fitness test I was very sore. My legs in particular, were in a great deal of pain. Luckily, this pain did not exist after the second fitness test. The reason for this is not really in any better shape to be taking a fitness test and running the Kosmin Test, rather, it is because after the second test I finally realized the importance of a cool-down. Anaerobic respiration lasts about 60 seconds at time, and coincidently, during the Kosmin Test we were running for 60 seconds at a time. This means that my muscles had just about maximized the amount of lactic acid they could produce, and I felt it. My coach in high school always stressed the importance of a cool down jog, but at the beginning of the month I thought to myself, “What’s just one time without a 800m recovery jog?” Well, I learned the hard way, as I could not walk normally for a few days.
It was a few weeks later in the course when I learned the biochemical reasoning behind the cool down. If the body is just idling it breaks down lactic acid at a much slower rate than it does when the body is undergoing light exercise. This is because the muscle cells can actually burn lactic acid during aerobic respiration.
Thanks to this course I learned tips (such as what not to eat before a workout and what to eat for optimal recovery) that will save me from a lot of pain and suffering during future workouts.
