Forceful Overarm Throwing
...and 25 boys, all from the same junior high school. Methods and Procedures: Data collection procedures for the current study followed closely of those used in 1979. Before the tests were administered the children were given verbal and written instructions and how the test was going to take place. Height, weight and their ankle, knee, elbow, hip joints, coronal midline, and spine were all marked using reflective markers. 3 practice throws were given before filming began and then the children were told to throw the ball as hard as they could into the gym wall from a marked spot on the floor that had cameras set up in certain places around it. Ball velocity was also collected and some participants threw up to 10 times. Before they threw the children were interviewed about their level of involvement in throwing skills. Results: After all data was collected, the ball velocities were to be analyzed and charted using a 2 X 2 analysis of variance. If anything, the 1999 group threw with slightly less velocity. Velocity in genders also did not change significantly and the boys showed the same velocity interval ahead of the girls as they did 20 years ago. Along with velocity being analyzed so was the film that had been collected on each participant. They then compared the level of humerus lag, forearm lag, and trunk action. W...
