Biomechanics
• application of mechanical principles in the
  study

• mechanics
  – branch of physics that analyzes the actions of
    forces on

Problems Studied by Biomechanists

• locomotion problems of animals
• effects of microgravity on the human musculoskeletal
  system
• effects of exercise on preventing or delaying
  osteoporosis
• effects of exercise on improving balance and strength of
  the elderly
• improving gait of children with cerebral palsy or persons
  with prosthesis
• prevention of work-related injuries and the improvement
  of working conditions and worker performance
• improvements in athletic performance
Biomechanical Studies Related to
Athletic Performance
• Wind tunnel experiments on bike helmets, optimal body
  configuration during ski jumping, and effects of wind
  resistance and altitude on track events
• Factors found to contribute to superior performance in
  the long jump, high jump, and pole vault
• Major mechanical factors affecting the flight of the discus
Biomechanical Studies Related to
Minimizing Sport Injuries
• overuse injuries caused by excess cumulative mileage,
  running on cambered surfaces, and improper footwear
• evaluation of protective helmets and ski boots and
  bindings
• efficacy of prophylactic knee braces
• safety and performance in sport shoe design
Why Study Biomechanics?

• Knowledge of basic biomechanical concepts are
  essential for the competent physical education teacher,
  physical therapist, physician, coach, personal trainer, or
  exercise instructor.

• It provides foundational understanding of
