My first artifact is my best mile time in the 28 day challenge, which was 7:40. The 28 day challenge was a booklet that we would put exercise data in to keep track of our exercises. We chose exercises based off 3 choices: upper body muscular strength, abdominal strength, and cardiovascular endurance. Before I tell you what I chose let me explain what all 3 of them mean. Muscular strength the limit that your biceps, triceps, and forearms have when they are faced with resistance. Abdominal strength is the limit that your abdominal muscles have against resistance. Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to your body. The faster and more efficiently your heart can do this the lower your heart rate will be. Cardiovascular endurance was what I chose for this challenge. My plan was to run 0.5 miles for 2 days, and then slowly increase to 1 mile. I chose cardiovascular endurance because in order for me to make the West Carrolton high school soccer team. To make the team I have to run a mile in under 7:00. Since my mile time was 8:49, I felt the need to improve upon that to have a shot at hitting that target. At the very end of the 28 day challenge I went for a run and rolled my ankle pretty bad and was not able to complete the 28 day challenge. But the fastest mile I ever ran was 7:40. Even though I didn’t reach my goal of 7:00 minutes I cut off a minute of my time. That was a major improvement for me.

              My 2nd artifact is the rates of my time for different distances, 7:52/1 is my rate when I ran ½ mile. 1 means 1 mile and 7:52 is my 0.5 mile distance time multiplied by 2. My fastest mile time rate would be 7:40/1. Even though as you run farther you slowly slow down until you can’t go anymore. These to rates come from the part of the 28 day challenge where we were doing our exercises. These 2 rates side by side definitely show growth because my mile rate is better than my ½ mile rate. This shows growth because as I said earlier as you run for a longer time, you get a little bit slower until you have to stop. But in this case I got faster which says that I had to have grown to beat my ½ mile time. Some terms that I learned while doing the 28 day challenge were, target heart rate which means a range of heart rates that a person sets for themselves before beginning an exercise. Power walk which is a walk where you walk really fast to keep your heart rate up (A.K.A. speed walk). Aerobic exercise which is an exercise that is easy enough that it allows your heart to pump enough oxygen to your muscles. I hope you have enjoyed reading about my evidence for my growth claim. I hope that I have given you enough information to convince you of my growth in fitness class.
