Biomechanics in pe vollleyball

Good morning students and teachers and whom this may concern, throughout this multimodal presentation I will be evaluating the video footage taken of my personal performance of the volleyball spike and I’m identify one major weakness in my technique and applying two biomechanical principles to justify why it is my weakness. Biomechanics applies to the science field in every sport; it is basically the principals and laws of mechanics about human performance.
Though the evaluation of the video footage which was taken to show my personal performance in the volley ball spike, it clearly shows the major weakness in my technique compared to the right technique. The basic correct technique for a spike is the three step approach, for a right handed hitter the approach is left foot, right food with build-up of momentum with arms swinging, and then left foot with arms swinging back forcefully behind the body palms up with energy going vertical, the take-off arms swing up forcefully with jump for increased vertical power, hitting arm in ready position opposite arm reaching high, execution, use core muscles and shoulder rotation to transfer power to hit the ball with elbow extended fully and the follow through is straight through the ball with a controlled landing. My major weakness with the volley ball spike is the approach and execution; through the footage of me you can clearly see this is my major fault.
Every lever has a point at which a certain force is applied, also a point of a fulcrum and a point of resistance, but the three different types of levers all play a role in sport and physical activity but still work slightly differently. The third- class levers have a force in between the resistance and the fulcrum; our forearms act as a third-class lever, with the elbow as the fulcrum or point of rotation of the lever. Through the third-class levers I can relate my personal performance due to the approach my arms are not in the right position and also in my execution,
