Flexor and Extensor Muscles

 * Topic:** Flexor and Extensor Muscles


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


 * Hypothesis:** I think the flexor muscle will be stronger then the extensor muscle because the flexor muscle pulls and the extensor muscle pushes.


 * 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.

Also in the data the average of a male and the average of a female both had their extensor exercise data higher then flexor exercises.**
 * Data**:
 * Conclusion: My hypothesis was that I thought the flexor muscle would be stronger. But I was so wroung. According to the data our averages of the data showed that we did more extensor exercises then flexor exercises. the average flexor times was 40.1 and the average for extensor times was 50.3. So on average in our class, people can do an average of 10 more extensors then flexors.
