What is Biomechanics?

"For Every Action there is an Equal or Opposite Reaction"

Newton's Third Law of Motion

Biomechanics is the study of motion. Biomechanics uses the principles of physics and the knowledge of anatomy to describe and measure motion.

There are two branches of biomechanics, these are kinematics and kinetics.

Kinematics describes the motion of the body and the key focus areas of the body. Kinematics can describe how far a body moves, how fast it moves and how that movement changes over time. An example of kinematics is measuring the knee and ankle angle at the time of foot contact during running, to determine if this technique could contribute to injury.

Kinetics describe why and how the movement occurs, which often includes measuring and describing the forces on a body. An example of kinetics is measurement of ground contact forces or the friction between the sole of a sports shoe and the ground surface to assess the effectiveness of a selected type of sports shoe.
