Document Summary

Lecture 7 - 27/03/18 - the mechanical basis of movement. Consideration of the forces, moments/torques, work, energies and powers in the body. Influence wether push or pull force: the magnitude of the force, amount. Examples of forces: gravity, muscle force, joint reaction force, ground reaction force, friction, fluid resistance. Forces in the body: external forces, forces on the body from the environment, e. g ground reaction force, forces from another person or object) Internal forces: forces acting between 2 locations within a single body, e. g loads on the bones from muscles or loads between bones, unit - newtons (n, form - vector. Kinetics - joint reaction forces: the joint reaction force in a body is the resultant force acting at a joint. It is the sum of all external forces (e. g ground reaction force) and internal forces (e. g muscle, ligament, tendon, bone) forces applied to the joint. It can be calculated to determine injury risk for particular movements of activities.
