Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** For my hypothesis I think that everyone will be able to do more with their flexor muscles then they will be able to do with their extensor muscles.


 * 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:** In my hypothesis I thought that the flexors would have more than the extensor's, and i was correct in what I said. When we averaged out the totals for the class the flexors did in fact have more than the extensors. The total aver for the flexors was about 29 and the total average for the extensor was about 25. The average for the females on the flexor was about 28 and the average for the extensor was about 20, and for the males the average for the flexors was about 30 and the average for the extensors was about 25. The reason that this happened i think was because you use you flexors more in life and you do your extensors. I also think that this happened because we did our flexor tests first and then like right after that we did our extensor muscles, so i think that the reason everyone got less on the extensor muscles was because everyones arms were already tired from the flexors.
