Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:**I think flexor muscles are stronger because that's the kind of muscles you are able to see the most.


 * 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 noticed that the average flexor muscles out of the whole class is 28.93 and the average extensor muscles is 23.07. The average male reps for flexor muscles is 29.82 and the average female flexor muscle reps is 27.77. The average extensor muscle reps for the male is 25.18 and the average female extensor muscles is 20.31.
