—STRAIGHT ARMS in the BACK BEAT:
This technique allows us to achieve a more pow- erful ballistic movement, since it involves a “sin- gle leverage point” (shoulders). However, we also lose some height in the back beat.
—BENT ARMS in the BACK BEAT:
This technique allows us to gain height in the back beat, because of a greater scapular retrac- tion and chest extension. However this will place more stress on the glenohumeral area than when using straight arms, due to the position of the hu- merus bones, thereby increasing the risk of in- jury.
While we may be able to reach more height, we will be losing power due to the shock absorp- tion effect of the arms (“double leverage point”, shoulders plus elbows).
