Movement Analysis Of Soccer Essay

Soccer is the most popular sport in the world with an estimated 200 million active players. The sport of soccer is performed by men, women, children and adults with different levels of expertise. The game is played on a rectangular field (100-110m by 65-75m) with a goal at each end. Each team has eleven field players including a goalie. The main objective of the game is to score by getting the ball into the opposing goal without using your hands. Soccer is an intermittent, labor intensive sport that requires players to perform repeated high-intensity about over the course of the game. Players maintain heart rate averages close to 85% of their maximum. Performing sprints, jumps, kicks and other explosive actions throughout the match increased
During phase 1, the abdominals, psoas major, erector spinae and spinal postural muscles are used to stabilize and rotate the trunk to the right. The gluteus maximus and hamstring group produce extension of the right hip while the gluteus med, gluteus min, hamstring group and adductor magnus externally rotate and eccentrically extend the left hip. The hamstring group and popliteus create flexion of the right knee while the quadriceps eccentrically extends the left knee. The plantarflexors cause plantarflexion at the right ankle and eccentrically plantarflex the left ankle. Lastly the middle and anterior deltoid and supraspinatus cause abduction of the left shoulder. This phase is defined as beginning with toe-off of the kicking limb and ends at maximum hip extension and knee flexion. (Brophy, et.al,
This phase is used to slow the body back to the starting position.
Kicking motion is achieved by a combination of muscle moments and motion dependent moments. Muscle moments are the result of high activation patterns of several muscles such as the hamstrings, quadriceps and iliopsoas whereas some muscle activity serves to stabilize the involved joints and segments in order to achieve a fine coordinated movement (Kellis & Katis, 2007).
In soccer the main source of energy is provided by the aerobic system. Soccer players need to be able to sustain a high rate of work for a period of at least 90 minutes. Though endurance is a huge component of soccer, soccer also is characterized by high intensity anaerobic efforts such as kicking. In kicking which is a short duration exercise, high energy intramuscular phosphagens and anaerobic glycolysis are used to produce maximal
