Using approximately 400-500 words, choose a sports skill you wish to analyze (note this will be the same sports skill used in a future Unit). Some examples include a free throw shot, softball pitch, soccer kick, baseball swing, etc. Discuss what movements occur at the ankle, knee, hip, spine, shoulder, elbow, and wrist. Compare the movements bilaterally, or both sides. In which planes do these movements occur? What axis of rotation occurs at each joint? Include at least two scholarly references (using APA formatting and style) to guide your answers.

< The three main forces that act on the patella are shown on the diagram of the knee joint below. These forces are the quadriceps muscle force (FQ), the patella ligament force (FPL), and the patellofemoral joint reaction force (FPF). The angles a and ẞ are with respect to a line that is perpendicular to FPF. Assuming a = 15°, ẞ = 20°, and FQ = 3725 N, use equations for static equilibrium to calculate (a) FPL, and (b) FPF. (Hint: To solve this problem consider using a coordinate system that is aligned with the principal axes of the patella instead of the usual vertical and horizontal axes). (c) Many people assume FQ and FPL are always equal in magnitude but this is only true under certain circumstances. Under what conditions are FQ and FPL equal in magnitude?

using the graph answer these questions Use the above graph of the sagittal ankle angle during walking to answer the following questions What is the maximum dorsiflexion angle and the maximum plantarflexion angle? What is the angular displacement (ROM) from 0.1 seconds to 0.55 seconds? What is the average angular velocity of the ankle from peak dorsiflexion to push off at the end of the stance phase? this is for biomechanics class
