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

1. Description of the motor skill performance
2. Anatomical analysis3. Mechanical analysis4. 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

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
