1 Course Objectives Huei-Ming Chai, Ph.D., PT National Taiwan University 09/ 12/ 2017 To describe the definition of Kinesiology To identify the importance of Kinesiology to physical and occupational therapists To understand the scope of Kinesiology and its current trends in research Required Readings Luttgens K & Hamilton N, chap 1 and chap 11 Definition of kinesiology origin of word of Kinesiology broad definition narrow definition Purposes of studying Kinesiology Scope of musculoskeletal kinesiology Broad Definition of Kinesiology the study of human movement kines = to move ology = to study scope biomechanics motor control exercise physiology Definition of Biomechanics the application of mechanics to the living system Physical properties of biological materials Biological signals and their measurements Biomechanical modeling and simulation Applications of biomechanics 1

2 Narrow Definition of Kinesiology the applied science of studying human movement by focusing on the anatomic and biomechanical interactions within the musculoskeletal system conventional definition scope kinematics kinetics Kinematics the study that describe the position and motion of the body in space displacement (x, y, z) velocity (x, y, z) acceleration (x, y, z) Note: velocity vs. speed Kinematic Parameters Displacement (m) Velocity (m/s) Acceleration (g) Kinetics the study that concerns with forces that produce, arrest, and modify motions of bodies f = ma M = I In this class, I will focus the Kinesiology on Kinematics.
