STUDY OF THE BODY MOVING

What is Biomechanics? Biomechanics is the science that examines the internal and external forces acting on a body, and the effect these forces have and produce. An external force example is Gravity Drag contraction A Body can be described as a human body an Object a person A force can be described as a push or pull strength something the jedi use External force comes from Within the body outside the body from the jedi An internal force comes from Within the body outside the body from the Jedi A Concentric force comes Through the centre of the body Off centre of the body A Eccentric force comes Through the center of an object Off centre of the body Which force creates spin Concentric Eccentrec An example of an internal force is Gravity Drag contraction Planes Name the planes in the picture belowFrontal Plane Sagittal PlaneHorizontal Plane Sagittal Plane Horizontal Plane Frontal Plane Static and Dynamic Forces Place the examples in the correct category. Static Forces Gravity: Gravity is a constant static force acting on the human body and all objects on Earth. It influences our posture, balance, and joint loading during activities such as standing, sitting, and lying down. Muscle Tension: When muscles contract and exert a force without changing length, it creates a static force. For example, during an isometric exercise like a plank, the muscles generate static forces to maintain the body in a fixed position. Joint Compression: Joint compression occurs when two or more bony surfaces are pressed against each other. For instance, when a person is standing upright, there is a static force pushing down on the joints of the lower extremities due to the body weight. Dynamic Forces Muscle Contraction: Muscles produce dynamic forces when they contract and change length, resulting in joint movement. Examples include movements such as walking, running, or lifting weights, where muscles generate forces to produce motion. Impact Forces: When a person jumps and lands on the ground or performs activities involving jumping or landing, there are dynamic impact forces acting on the body. These forces change rapidly and can be significant, affecting the joints and muscles involved. Angular Forces: Angular forces are dynamic forces that cause rotation or twisting movements around joints. For instance, during throwing or swinging motions, such as in a baseball pitch or a golf swing, angular forces are generated and transferred through the joints, muscles, and tendons.
