Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** I think that both the extensor muscle and the flexor muscle would be equal strong, because when you flex you tend to use the extensor muscle afterward, therefore they would both be equal strong.


 * 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:** According to my data i was right & also wrong. For my hypothesis i said the extensor and the flexor muscle would both be equaling strong together. I will now begin to explain why, you see because The boys were able to do more extensor than the flexor exercise, but most of the girls could not. They were equal also, because both the girls and guys were able to do an equal amount of flexor exercising.
