| | Abstract | I feel your size doesn’t affect your velocity but your mechanics does. If a |
| | pitcher has a shorter arm, then he’ll have a higher velocity fastball. I |
| | conducted an experiment to test my theory that arm length is irrelevant to |
| | the velocity of your fastball. My procedure was, find 15 guys, measure the |
| | length of their throwing arm from middle finger tip to shoulder, 18.4 meters |
| | from mound to plate, make sure the weather is very similar for each |
| | participant, have them throw 15 warm up pitches, record the next 10 |
| | pitches (only fastballs) with the radar gun, take the average of the ten |
| | pitches and record, make a chart with arm length on the x axis and speed |
| | on the y axis, analyzed my data, compared the data of speed from short |
| | arm pitchers to long arm pitchers and seen if there was a relation, wrote |
| | my conclusion proving or disproving my hypothesis. |

| | My data proved that the length of your arm doesn’t affect the velocity of |
| | your fastball. I was pleased with my results because I wanted to do an |
| | experiment that proved to myself and others that size doesn’t play a role in |
| | pitching. |
