HEAL1000 Lecture Notes - Lecture 2: Anatomical Terms Of Motion, Systematic Chaos
Document Summary
Movement analysis- apply the principles of biomechanics to analyse functional tasks. A synthesis of biology and mechanics that seeks to understand and explain human movement. The study of the action of forces on the structure and function of living things. There are two types: kinematics- describes motion (displacement and acceleration, kinetics-forces that cause motion (force or torque) Scalar and vector quantities: scalar=magnitude only (mass, distance, speed, time, vector=magnitude and direction (force, displacement, acceleration, velocity) All parts of the body move through the same displacement, in the same direction at the same time (running: angular-rotation about an axis. All parts of the body move through the same angle in the same direction at the same time (spin dive: general-mixture of both linear and angular (cycling) Sagittal- from side on (flexion and extension)-spin dive. Linear displacement (s)-change in location from the initial to the final position. Linear velocity(v)-the rate of change in displacement (can be negative)
