CHAPTER 1: KINEMATIC VARIABLES OF LINEAR AND ANGULAR MOTION
Kinematics is the study of basic biophysical concepts pertaining to the precise
description of both spatial and temporal characteristics of angular and linear motion without considering the forces causing the motion. Kinematics is key to understanding the biophysics of humanmovement studies with the help of five fundamental variables used to describe motion of human body systems, composed of joined parts of the skeleton, which includes type, position, direction, magnitude, and rate of motion. This chapter presents information on the types of motion, magnitude of angular motion expressed as range of motion, planes of motion, axes within the body, movementtypes about the three axes, mathematical description of the rectilinear and curvilinear motion in different coordinates, concepts on kinematic chains.
Key words: Kinematics, types of motion, magnitude of displacement, direction, position and rate of motion, kinematic chain
Kinematics is the branch of dynamics which deals with the qualitative and
quantitative description of both spatial and temporal characteristics of angular and linear
motion without considering the forces causing the motion (Whittle 2002; Shumway-
Cook and Woollacott 2001). Kinematics is used in human movement studies to describe
the motion of systems composed of joined parts of the skeleton of the human body. There
are basically five variables used to describe motion in kinematics: type, position,
direction, magnitude, and rate of motion.
