Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:**I think the flexor muscles are stronger that the extensor muscles. I was able to do 150 reps with my flexor muscles and only 37 with my 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:** My conclusion is that the flexor muscles are stronger. For the male's, we were able to do more reps with our flexor muscles instead of reps with our extensor muscles. Same with the females, their percentage of reps were higher when they were working with their flexor muscles instead of their extensor muscles. There fore the flexor muscles are stronger than the extensor muscles in both sex's, male and female.
