Description

Procedure Part 1 1. Hold a book in each hand. 2. Raise one arm straight out parallel to the ground and the other arm down at your side. 3. Measure the length of time you can hold the book out parallel to the ground. 4. Answer the following reflection questions: A. How long were you able to hold the book parallel to the ground? I was able to hold the book parallel for 2 minutes and 6 seconds. B. What muscles experienced the most fatigue? I feel that my triceps experienced the most fatigue.

Procedure Part 2 1. Sit against the wall with your knees bent at a 90-degree angle. 2. Measure the length of time you can hold this position before you feel muscle fatigue. (Hint: If it has been more than three minutes you might not be doing it right!). 3. Walk around for 30 minutes immediately after this activity, make observations about how it feels. 4. Answer the following reflection questions: A. How long did you sit before your legs felt fatigued or started to burn? I was able to sit for about 30 seconds before I started feeling fatigue, but I was able to stay without a prominent burn for a little over a minute. B. How did it feel to walk immediately after sitting against the wall? After doing this exercise, my legs felt like they were starting to cramp, and felt really tight and limp. C. Explain, in a few sentences, what causes this feeling of fatigue in your legs? I feel that the consistent tight hold was causing the muscles to work harder to keep the position, rather than tightening and releasing as with a walking motion....
