12
What is Biomechanics?

• Biomechanics is the science that examines forces
  acting upon and within a biological structure and
  effects produced by such forces.

13
What is Biomechanics?

• Biomechanics is the science that examines forces
  acting upon and within a biological structure and
  effects produced by such forces.

14
What is a Force?

• A force can not be defined.
• Only the effects of forces can be described.

15
What is Biomechanics?

Different Areas of Biomechanics

• Animal
• Clinical
• Muscle
• Orthopaedic
• Sport

40
Animal Biomechanics

• Why do horses change
• gait between walking,
• trotting and galloping?
• How do spiders jump
• without leg extensor
• muscles?

41
Clinical Biomechanics

• Will excess foot pressure be relieved with an
  orthotic?

• Will a specific ankle brace promote healing of a
  severe ankle sprain?

42
Muscle Biomechanics

• How does a muscle produce force?
• What governs the distribution of forces of
  several active muscles?

43
Orthopaedic Biomechanics

• How can we design a more effective hip implant?
• How can we prevent or treat osteoporosis?

44
Sport Biomechanics

• How can pitchers generate ball speeds of over 90
  miles/hr?
• Why do jumpers use the Fosbury flop?
