Extensor+and+Flexor+Muscles


 * Topic:** Flexor and Extensor Muscles


 * Question:** Which muscles are stronger, flexor or extensor muscles?


 * Hypothesis:** I think that the Flexor Muscle is stronger that the extensor muscle. I think our class will be able to do more of the flexor exercises because we use our biceps more often.


 * Procedure:**
 * 1) Get into groups
 * 2) Have one person stand up straight with his / her back against a wall.
 * 3) Have that person hold the weights in his / her dominant hand
 * 4) In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
 * 5) Repeat steps 2-4 for each member of the group.
 * 6) Record the data for each member of the group.
 * 7) Have the first person stand as straight as possible near a wall.
 * 8) Have the student hold the weights with his / her dominant arm bent near the ear.
 * 9) In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
 * 10) Repeat steps 7-9 for each member of the group.
 * 11) Record the data for each member of the group.

 * Conclusion:** I thought that we would get higher scores for the flexor exercises because we use those muscles more often. I was right! The scores for the flexor exercise were higher than the scores for the extensor exercise. The score for the flexor was, 28.93333333 and the score for the extensor was, 23.06666667. We also sorted the information according to male and female. There wasn't that much of a difference expect the average for the male was a little higher. The score was the male was, flexor: 29.82352941, Extensor: 25.17647059 and the score for the female was, flexor: 27.76923077, extensor: 20.30769231.
