 We can take a closer look at PC2 and PC5 to see why these principal components may be showing the most significant differences. Looking at the mean signal trace of the college and high school subjects pelvic internal/external rotation, we can see that the majority of the difference in their swings are at the peak of their pelvic velocity, and also interestingly the high school players have more internal rotation before and at the end of there swing which is represented in PC2. PC5 is less clear and harder to interpret, once again we can see that the high and low points around 80-90 on the x axis are showing the variability between the subjects peak pelvic angular velocity, and the large value around 40 seems to point out that there were more college players with an earlier swing, but the rest is hard to decipher. We can take a closer look at PC2 and PC5 to see why these principal components may be showing the most significant differences.
