Skipping Research Paper

I have chosen a skill from an extra curricular sport activity I participate in outside of school. It is called skipping. The skill I have chosen is one of the many skills I have learnt from participating and competing in this sport. This skill requires many different muscles, bones, joints and their actions. Before I perform my skill I jump over the rope twice quickly and then slowly once. To jump over the rope, I use flexion to bend my elbow joint, moving my radius and ulna in a circular motion from my elbow joint and my shoulder joint uses circumduction to bring the rope over my head. My bicep brachii allows me to flex my elbow to perform this skill. I flex both my knee joints to prepare to jump the rope and to gain power. My hamstrings allow me to bend my knee joint, allowing …show more content…
The next movement is extending at the knee joints. When I extend the knee joints my quadriceps and gastrocnemii allow me to jump high off the ground. As my feet are leaving the ground I start to make my next movement with my shoulders and wrists. I start to swing the rope to the other side of my body so I can make my next movement. My shoulder joint uses circumduction to perform this part of the skill. While moving the rope to the other side of my body using my shoulders I am also rotating my wrists. This movement uses my latissimus dorsi muscles to move my left radius, ulna and humerus to the right side of my body and my bicep brachii to flex both my elbow joints. When my hands in line with my body and my feet are off the floor I start to flex my right hip joint so my leg is inline with my hip joint. My quadricep allows me to flex my hip joint. This allows me to form the shape that is needed in this skill. I am able to flex my hip joint, as it is a ball and socket joint. Simultaneously I flex my knee joint using my hamstrings. This also allows me to create the shape needed for this
