How The Ball With Your Foot

Introduction
In America it is called soccer, but in the rest of the world it is called football. This sport consists of a ball being kicked with feet with the intent of getting the ball into the goal. The faster the ball moves, the less time the goalie has to prevent a goal from being scored. If the ball is kicked directly at the goalie with incredible speed, the ball will be deflected and not go into the goal. Occasionally a player must direct the ball around many additional players to get a free shot which can be a lot of hard work. Sometimes though, a player gets a free shot. This uninhibited shot doesn’t necessarily mean free points though. Most shots that score have a rapid velocity and are very accurate. There are two main ways of

The approach includes the steps before the foot plant. This article found that the greater distance the step is up to 1.6m the more powerful the kick will be. The biomechanical purpose of this phase is to generate power by increasing momentum. The contact phase occurs after the opposite foot has been planted and is the “beginning the forward motion of the kicking leg onto the impact on the ball” (What… 2014). During this phase the flexion of the knee in the kicking leg increases to cause an overall deceleration of the player but an increase in acceleration of the kicking leg to generate more velocity. The follow through phase is where contact is made and the kicking leg comes closer to the elbow on the same side of the body as the kicking leg. The leg essentially completes the path it began in the forward swing of the kick. The article goes on to mention the main biomechanical principles that influence a player’s ability to achieve maximum velocity. They are the angular velocity of the lower limbs, coefficient of restitution, and ground reaction force. In the research article “Three-dimensional kinetic analysis of side-foot and instep soccer kicks” by Hiroyuki Nunome, Takeshi Asai, Yasuo Ikegami, and Shinji Sakurai, they found “The average ball velocities of the side-foot and instep kicks were 23.4 +/- 1.7 m·s-1 and 28.0 +/- 2.1 m·s-1, respectively” (Nunome 2002). This showed how the instep kick was
