Anatomy : Rugby Kick- preparation phase
During the preparation phase of a rugby kick, the right leg moves back in a back swing. The movement is hip extension which involves the ball and socket joint (hip).The bones involved are the tibia, fibula, femur and potella. The agonist is the gluteus maximus and the hamstring. The antagonist is the hip flexors. The right knee which is a hinge joint also flexes. The muscles that cause knee flexion are the hamstrings which are the agonist, and the antagonist muscle is the quadriceps. This movement occurs because muscles work in pairs across a joint. When one muscle contracts, the other one relaxes.

Examples of the preparation phase of a rugby kick.

This is because they are receiving more blood and oxygen and they increase in temperature. I also will sweat because my body temperature had increased (sweating is the bodies response to cool it down). The body temperature increases/heats up because the muscles are working harder and creating friction which therefore creating excess heat. In my cardiovascular system, my heart rate will increased because I will be needing more blood to be pumped around the body to my muscles. For my respiratory system, my breathing rate will increase as I will be taking in more oxygen as I begin to come out of breath and fell tired quickly. I am now therefore exhaling more carbon dioxide as I am taking in more

Are We Actually Training for Speed? Essay

Are We Actually Training For Speed?
