Biomechanics
•The term biomechanics combines the prefix bio,
meaning “life,” with the field of mechanics, which is the
study of the actions of forces.

Biomechanics
•The international community of scientists adopted the
term biomechanics during the early 1970s to describe
the science involving the study of the mechanical
aspects of living organisms.

Anthropometry
•Anthropometry (Greek anthropos- "man" and metron -
"measure") therefore "measurement of man") refers to
the measurement of the human individual.

Anthropometry
•Anthropometry plays an important role in industrial
design, clothing design, ergonomics and architecture
where statistical data about the distribution of body
dimensions in the population are used to optimize
products.

Scientific Scope Of Biomechanics
•The biomechanical principles are applied by scientists
and professionals in a number of fields to problems
related to human health and performance.
Knowledge of basic biomechanical concepts is also
essential for the competent physical education
teacher, physical therapist, physician, coach, personal
trainer, or exercise instructor.

BIOMECHANICS RESEARCH
Developmental biomechanics
Evaluate fundamental movement patterns in
performing gross (crawling, walking – involve large
muscle group) and fine motor skills (manipulating
small objects, transferring object – involve small
muscle group).

BIOMECHANICS RESEARCH
Occupational Biomechanics
Focuses on providing safe and efficient working environment, both indoors and
outdoors.
•Better Safety equipment – helmets, shin guards,footwear to protect from
any work hazards.
•Safe and ergonomic working tools to minimize overuse injuries of both
upper and lower limbs
•Designing of mass public transportation – airplanes,trains,boats and
automobiles for safety and efficiency.
•Close allied with the science of ergonomics

BIOMECHANICS RESEARCH
Rehabilitative Biomechanics
Observe movement patterns of individuals who are
either injured or/and disabled, provide appropriate
interventions which enable injured and disabled
person to function as close to, if not normally.
Develop exercise equipment, supplementary aids such
as walkers, orthotics and even substitution devices
such as prostheses for rehabilitation purposes.
