Human movement can be analyzed from the perspectives of mechanics, anatomy, and physiology. Biomechanics studies the mechanics of movement, musculoskeletal anatomy analyzes the bones and muscles involved in movement, and neuromuscular physiology examines how the nervous system controls muscles during movement. Movement is analyzed for safety to avoid harm, effectiveness in meeting performance goals, and efficiency in achieving the goal with least effort. Therapists and trainers focus on restoring function while movement professionals focus on performance. Skills are described, evaluated, and corrected based on relevant anatomical and mechanical principles.

Human movement from the point of view of the physical sciences. Mechanics: Biomechanics Anatomy: Musculoskeletal anatomy Physiology: Neuromuscular physiology Every structure that participates in movements of the body does so according to physical and physiological principles.
Safety structure movements to avoid harm to the body Effectiveness success or failure of meeting performance goals Efficiency striving to achieve movement goal with least amount of effort
Therapist & athletic trainers Primarily concerned with effects that exercise has on the body for restoration of impaired function Movement/Fitness professionals Primarily concerned with creating effective performance the normal body or extending care
Describing a skill in a logical fashion Fundamental elements / components Evaluating performance how related anatomical & mechanical principles occur and/or have been violated. Prescribing corrections based on appropriate identification of cause
Description of the motor skill performance Anatomical analysis Mechanical analysis Prescriptions should be aligned with: motor skill, anatomical analysis, and mechanical analysis
Primary purpose of the skill Speed, accuracy, form, etc Movement phases Classification of the skill Posture—standing, seated, supine Movement purpose: PA, fitness, performance Motion Focus (internal /external) Nature of motion Simultaneous – segments move as one Sequential – segments in an orderly sequence
Joint actions & segment motions: Joints are involved Exact movements in skill Any limited range of motion Muscle participation & form of contraction: Muscles produce joint actions Type of contraction
Nature of forces causing or impeding motion Ex: Difference in Left/right during gait Modifying forces Mechanical factors: balance, forces, direction, timing, etc. Violation of principles: No optimal application of mechanical factors What are the sources of error?
. Improvement of performance Strategy for effecting change Based on kinesiological analysis Modify principles (motor, anatomical, mechanical) be so that movement performance may be optimized Concentrate on the causes of dysfunction, not on the symptoms
Analysis Model Which anatomical principles contribute to efficiency or accuracy? Which principles are related to avoidance of injury? Joint Joint Action Segment Moved Plane & Axis Force Contraction Type Prime Movers
