ESS 303 – Biomechanics
Why Study Biomechanics?
What’s the Motivation?
Required for
major?
Earn credits
towards
graduation?
Why are sport
skills/techniques
the way they are?
Etc.
What is Biomechanics?
 The study of the
structure and function of
biological systems by
means of the methods
of mechanics.
 Combines the
disciplines of
mechanics (physics),
biological structure
(anatomy), and
biological function
(physiology)
Part of Kinesiology & Sports Med.
 Kinesiology: The study of human movement
 Adapted PE, Exercise Physiology, Motor Behavior,
Athletic Training, Sport History, Pedagogy, Sport
Philosophy, Sport Art, Sport Psychology, Etc.
 Sports Medicine: An umbrella term that
encompasses both clinical and scientific
aspects of exercise and sport
 Athletic Medicine, Exercise Physiology, Physical
Therapy, Cardiac Rehabilitation, Motor Control,

Units of Measurement
 Joe forgot his wedding anniversary
 His wife was really angry
 She told him “Tomorrow morning, I expect to find a gift in the
driveway that goes from 0 to 200 in less than 6 seconds AND IT

 Confused, the wife put on her robe, ran out, and brought the box
in the house
 She opened it and found a brand new bathroom scale
 Joe has been missing since Friday
