Experts review the basic principles of biomechanics and how the study of human movement has evolved over time. Presenters highlight examples in applied kinematics, applied kinetics and applied neuromuscular/motor control and demonstrate how methodologies vary depending on the field of study or area of expertise.

5. Mission, to be a catalyst for the scaling and use of
biomechanics from the research environments to the applied
science world of clinicians, specialists, and sports scientists.
From my experience, these clinicians are searching for objective
ways to assess and monitor their patients/athletes, which I
believe biomechanics is the solution.
Coleman Bessert
6. Mission: to contribute towards the advancement of evidence-
based healthcare services in Africa through the development of
world-class research facilities, professional expertise and
student training curricula.
John Cockcroft
7. Biomechanics: the study of
the structure and function of
biological systems using the
principles of mechanics.
TODAY’S FOCUS:
Human musculoskeletal
biomechanics: the study of
the structure and function of
the human musculoskeletal
system during functional
movement.
8. Electromyography (EMG):
Recording of the electrical
activity produced by skeletal
muscles.
TODAY’S FOCUS:
Kinesiological EMG: the
recording of electrical activity
produced by skeletal muscles
during movement.
Surface EMG: the recording of
electrical activity using
electrodes mounted on the
skin surface.

“Father of Kinesiology”
~400 B.C.
Galen,
“Father of Sports Medicine”

WHAT WERE THE MAJOR ADVANCEMENTS THAT
FOLLOWED?
10. New discoveries about the human body
- Systematic dissection of human cadavers
- Establishment of anatomy as a discipline
Development of mathematical disciplines
- Analytical geometry
- Newtonian mechanics

27. A Snapshot. One to many tests
that provide insight into an
individual’s compensations and
restrictions.
Injury Prevention or Rehab. The
continual re-assessment to track
progress and intervention impact.
Training Tool. Leveraging visual,
auditory, and tactile senses to
increase the rate of recovery.
Outcome Data. Measure the
outcome of the rehab or training
effect on the athlete in an
uncontrolled chaotic environment.
28. Forces. Ability to express, control, and
stabilize external load on the body.
Motion. Joint mobility and stability

effort, coordination, and symmetry.
29. Baseline, allowing for practitioner's to rapidly gain
insight into key athletic qualities and capabilities.
30. Confirming your Intuition. Subjective
assessments are only as good as the
practitioner. Objective data can be used
to standardize and remove intra- and
inter-tester variability.
