Introduction to Kinesiology & Biomechanics Definitions Kinesiology Biomechanics Definitions Kinematics Kinetics Definitions Static Analysis Dynamics Analysis Definitions Anthropometrics Why study biomechanics? Biomechanist vs Applied Biomechanist Sports Performance Ergonomics Injury Prevention Improved Rehabilitation Ways to Solve Biomechanical Problems Qualitative vs Quantitative Scalar vs Vector Quantities Basic Structural Analysis Stress-Strain Curve Stress Strain Key Points on Curve Elastic Modulus Yield Point Plastic Region Elastic Region Residual Strain Failure Safety Factor Mechanical Energy Basic Structural Analysis Stress-Strain Curve Stress Strain Key Points on Curve Elastic Modulus Yield Point Plastic Region Elastic Region Residual Strain Failure Safety Factor Mechanical Energy Basic Structural Analysis Stress-Strain Curve Stress Strain Key Points on Curve Elastic Modulus Yield Point Plastic Region Elastic Region Residual Strain Failure Safety Factor Mechanical Energy = ½ stress * strain Area under the curve Types of Materials Elastic Linear relationship between stress & strain Types of Materials Viscoelastic Nearly all biologic tissues Manifestations of Viscoelastic Properties Rate of Loading Hysteresis Creep Types of Materials Viscoelastic Nearly all biologic tissues Manifestations of Viscoelastic Properties Rate of Loading Hysteresis Creep Types of Materials Viscoelastic Nearly all biologic tissues Manifestations of Viscoelastic Properties Rate of Loading Hysteresis Creep Types of Materials Viscoelastic Nearly all biologic tissues Manifestations of Viscoelastic Properties Rate of Loading Hysteresis Creep Material Characteristics Stiff Compliant Brittle Review Anatomical Terms Directional Terms Superior/Inferior Proximal/Distal Anterior/Posterior Medial/Lateral Superficial/Deep Movement Terms Flexion/Extension Abduction/Adduction Horizontal Abduction/Hor. Adduction Internal Rotation/External Rotation Radial Deviation/Ulnar Deviation Supination/Pronation Inversion/Eversion Reference Systems Reference Systems Why? Absolute vs Relative Absolute Reference Frame Segments intersect in joint center & movement of segment is described with respect to that joint Reference Systems Why? Absolute vs Relative Absolute Reference Frame Relative Reference Frame Movement of segment described relative to adjacent segment Reference Systems Up (+) z x Forward (+) Spatial Reference Frame Movement of body relative to ground Occurs in xyz directions Down (-) y Left (+) Backward (-) Right (-) Reference Systems Cartesian Coordinate System Fixed reference point x,y and z coordinates Anatomical Planes & Axes Plane of Motion 2 dimensional flat surface Axis point about which movement occurs perpendicular to the plane of movement Whole Body Planes and Axes Segmental Planes and Axes Anatomical Planes Planes of movement Sagittal left/right halves Perpendicular Axis Frontal or Mediolateral Planes & Axes Frontal Plane Anterior/posterior halves Axis Anteroposterior or Sagittal Planes & Axes Transverse Plane Upper/lower halves Axis - Longitudinal Other Planes and axes Diagonal or Oblique plane of movement perpendicular to the plane how to find
