Biomechanic course

  1. 1. Introduction to Biomechanics Objectives: • Define basic concepts in biomechanics • Provide an overview of the sports and clinical applications of biomechanics What is Biomechanics?• Mechanics the study of the action of forces on particles and mechanical systems; a branch of physics• System an object or group of interacting objects• Biomechanics application of the principles of mechanics to the study of living organisms (e.g. the human body and its parts) 1
  2. 2. Sub-branches of Mechanics• Statics branch of mechanics dealing with systems in a constant state of motion; includes systems that are: – at rest (i.e. not moving) – moving with a constant velocity• Dynamics branch of mechanics dealing with systems in which acceleration is present (i.e. where velocity is not constant) Subdivisions of Mechanics• Kinematics the description of motion, including: – considerations of space and time – patterns and speeds of movement sequencing the forces causing the motion are not considered• Kinetics study of the relationship between the forces acting on a system and the motion of the system 2
  3. 3. Additional Terminology• Kinesiology the study of human movement (Hall, 2003)• Anthropometry study of the mechanical properties of body segments (e.g. dimension, weight, etc.) Who Uses Biomechanics? • Phys.Ed. Teachers • Coaches • Athletic Trainers • Physicians • Physical Therapists • Engineers • Researchers 3
  4. 4. What is Biomechanics Used For? Improving Sports Performance (MLB) (Viking) technique equipment (e.g. klapskates) Sports Injury Preventionapplied force > tissue strength → injury (Oregon State) (AirCast) technique protective equipment 4
  5. 5. Occupational Injury Prevention (Ergonomics) (Ohio State) hand & wrist (Ohio State) trauma low back pain Injury Rehabilitation FORCES Passive motion Strength training RE-INJURY BikingTIME Full wt.bearing Squats Running Jumping Cutting 5
  6. 6. Reducing Physical or Functional Declines osteoporosis (NASA) effects of falls in older space flight adults Improving Mobility (Vicon) surgery planning in cerebral palsy 6
  7. 7. Product Design(Vicon) (Össur)athletic shoes Flex-foot artificial hip Why Study Biomechanics? • Biomechanics: – has many and wide-ranging applications within health and sport sciences – is used by professionals throughout health and sport sciences • This course will provide a foundation for: – understanding the mechanical principles underlying human movement – applying these principles to the analysis of human movement • Understanding biomechanics will make you a more competent professional ! 7
