Study Notes

Biomechanics Definition

  • Biomechanics studies how forces affect living organisms, by combining the study of "life" with the study of forces.
  • The forces it studies include internal forces from muscles as well as external forces acting on the body.
  • Biomechanics analyzes the mechanical aspects of living beings.

Biomechanics Subbranches

  • Statics studies systems with constant motion, whether at rest or moving at a constant velocity.
  • Dynamics studies systems that are subject to acceleration.
  • Kinematics studies the description of motion, focusing on size, sequencing, and timing of movement, without considering the forces involved.
  • Kinetics studies the forces associated with motion.

Kinesiology and Sports Medicine

  • Kinesiology is the study of human movement.
  • Sports medicine encompasses both clinical and scientific aspects of exercise and sport.

What Do Biomechanists Study?

  • Biomechanists study the mechanics of living organisms, including humans and animals.
  • They examine a broad range of problems, including:
    • Movement and Locomotion
    • Injury Prevention and Rehabilitation
    • Sports Performance
    • Orthopeadic Biomechanics
    • Gait Analysis
    • Prosthetics and Orthotics
    • Tissue Mechanics
    • Movement Disorders
    • Biomechanics of Aging
    • Animal Biomechanics

Units of Measurement

  • The English system of weights and measures was primarily developed in England and is still used in the United States.
  • The Metric system is used internationally for scientific purposes and daily use in most of the world.

Professions that Rely on Biomechanics

  • Professionals in various occupations use biomechanics on a regular basis to understand and apply its principles.
  • Some of these professions include:
    • Physical education teachers, coaches, and personal trainers
    • Sport analysts
    • Golf coaches
    • Athletic trainers, physical therapists, and chiropractors
    • Prosthetists and orthotists
