Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** I think that the extensor muscle are stronger than the flexor muscle because i think that it would be easier to make something straight and hold it then it would be to lift something up.


 * 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 stated that extensor muscles were stronger than flexor muscles and my hypothesis was correct. My hypothesis was correct because in the data the extensor averages were larger than the flexor averages. The average for the flexor muscle was 40.1. The average for the extensor muscle was 50.3. The male average for the flexor muscle was 55.6. The male average for the extensor muscle was 64.6. The female average for the flexor muscle was 27.9, and the female average for the extensor muscle was 39.0. So my hypothesis was correct.
