Published on

This learning module takes a look into the bioengineering world from the perspective of every day activities. The activity that this part of the module focuses is on kicking a soccer ball and the bones/joints, muscles and forces that are involved. This is the powerpoint supplement to the learning module. See PDF file with the same title for lesson plan. Target Grade: 6th

  • The human body contains more than 650 individual muscles which are attached to the skeleton, which provides the pulling power for us to move around. The main job of the muscular system is to provide movement for the body. The muscular system consist of three different types of muscle tissues : skeletal, cardiac, smooth. Each of these different tissues has the ability to contract, which then allows body movements and functions. There are two types of muscles in the system and they are the involuntary muscles, and the voluntary muscles. The muscle in which we are allow to control by ourselves are called the voluntary muscles and the ones we can control are the involuntary muscles. The heart, or the cardiac muscle, is an example of involuntary muscle.
  • We can ask students to demonstrate
  • The Approach: As a child develops their kicking pattern they learn to pace the run up and adjust their approach into a diagonal angle. A 45-degree angle produces the greatest peak ball velocity.Plant-foot Forces: The ground reaction force on the plant foot directly affects the ball speed. There is also a direct relationship between the direction of the plant foot and the direction the ball travels. The most accurate direction of the ball can be accomplished when the foot plant position is perpendicular to a line through the center of the ball. The optimal anterior-posterior (A-P) position of the plant foot is adjacent to the ball. This A-P position determines the flight path of the kicked ball.Swing-limb loading: The swinging of the limb prepares for the descending motion towards the ball. During this phase the opposite arm is raised to counter balance the rotating body. Both arms help keep the center of gravity over the support foot and increases the moment of inertia of the trunk. The kicking leg is extended and the knee is flexed to store elastic energy and allow a greater transfer of force to the ball. At the end of this phase there is maximal eccentric activity in the knee extensors. Hip flexion and knee extension: In this phase the thigh is swung forward and downward with a forward rotation of the lower leg. The leg then begins to accelerate due to the combined effect of the transfer of momentum and release of stored elastic energy in the knee extensors. The knee extensors then powerfully contract to swing the leg and foot towards the ball. After the kicking leg makes contact with the ball the knee is extended and the foot is plantarflexed. At this time the hamstrings are maximally activte to slow the leg’s eccentric movement. Foot contact with the ball: When the foot makes contact with the ball 15 % of the kinetic energy of the swinging limb is transferred to the ball and the rest of the energy is used by the eccentric activity of the hamstring muscle group to slow the limb down. Follow –Through: This serves to keep the foot in contact with the ball to maximize the transfer of momentum and therefore increase speed. This also serves to guard against injury by gradually dissipating the kinetic and elastic forces.
