Biomechanics
• is adiscipline within physical education that
applies form physics, biology, and engineering
to the study of the movements and forces of
living organisms, especially the human body.
• the term biomechanics is derived from the
Greek words: Bio - meaning life, Mechanics -
referring to the physics and forces that act on
moving bodies.
3.
• biomechanics hasmany practical
applications, such as developing new
medical treatments, designing better
sports equipment, improving athletic
training techniques, and optimizing
workplace ergonomics.
• by analyzing movement and mechanics,
biomechanics can enhance human
performance, prevent injuries, and
improve quality of life.
• it helps us understand how the body
moves, the forces acting on biological
structures such as muscles and bones,
and the mechanics of biological systems.
4.
Elements of Biomechanics
InBiomechanics, there are 5 important elements or components: They are briefly discussed below.
• The movement of a
body or an object
across space. Speed
and acceleration are
major elements of
motion.
MOTION
• This is the push or pull
that causes a person
or an object to
accelerate, decelerate,
stop, or change in
motion.
FORCE
• This refers to stability.
The alighnment of body’s
center of gravity over the
base of support is a
fundamental principle of
balance.
BALANCE
Our arms and legs
function as levers; a lever
has three parts: the
resistance arm, the
fulcrum, and the axis of
rotation
LEVERS
• This is the product of
a weight and its
velocity when it is
moved.
MOMENTUM
5.
Principles Used inBiomechanics
Dynamics: The study focuses on
analyzing forces.
Kinetics: The study is to analyze the forces
that cause motion.
Static: The study is concerned with analyzing bodies
that are at rest or in a state of balance.
Kinematics: The study is to analyze the position, velocity, and
acceleration of the body segments and joints without
considering the force that cause motion. it describes the motion
in terms of space and time.

Objectives of Biomechanics
•The primary objective of biomechanics of a sport and
physical exercise is to increase performance in a
particular sport or physical exercise. In a broader sense,
the objective of biomechanics of sport and physical
exercise is to improve physical fitness. For example, the
proper biomechanics of running enables athletes to
engage in regular physical activity for extended periods
of time without being substantially hindered by injuries
and their effects.
• The secondary objective of biomechanics of sport and
physical exercise is to make recommendations for injury
prevention and rehabilitation. This secondary objective
of sport biomechanics is inextricably linked to the first
objective since a healthy athlete will outperform an
injured athlete.
7.
Biomechanics is afascinating field that allows
us to understand human movements like
never before. By utilizing a variety of tools
and instruments, we can measure and analyze
physical performance with incredible
accuracy.

These directional termsare commonly used in anatomy and
physiology to described the relative positions of body
structures and locations. It is essential to understand these
terms to communicate effectively and accurately about the
human body’s structure and functions.
On the other hand, body planes are imaginary lines or
planes that are used to divide the body into sections,
allowing for more precise description and communication
of anatomical structures and locations.
15.
A plane thatruns vertically
from side to side and divides
the body or it’s part into
front and back sections.
Coronal Plane (Frontal Plane) Sagittal Plane (Lateral Plane)
Axial Plane (Transverse Plane) Median Plane
A plane that runs vertically
from front to back and
divides the or its part into
right and left sections.
A plane that runs
horizontally and separates
the body or its parts into
upper and lower portions.
The sagittal plane divides
the body or its sections into
right and left halves as it
passes through the midline
of the body.
16.
Understanding these planesis
essential for accurately describing the
location and relationships between
anatomical structures. By using these
planes in combination with directional
terms, healthcare professionals can
effectively communicate with one
another and provide the best possible
care for their patients.
17.
The Anatomical movementsand locations are described using
terminologies below:
• FLEXION - bending joint, as in knee oe elbow flexion, to
reduce the angle between two bones.
• EXTENSION - the opposite of flexion, in which a joint is
straighten to widen the angle formed by two bones, as when
straightening an elbow or knee.
• MEDIAL ROTATION - the movement of a limb or body part in
the direction of the body’s midline, as when the
shoulder is turned in that direction.

closer to the body’s
midline or center, as
when bringing the legs
together
ABDUCTION
• moving a body part
from the midline or the
enter of the body, as
when the legs spread.
DEPRESSION
• lowering or dropping a
body part, such as
lowering the shoulder.
ELEVATION

part in circular motion,
such as tracing a circle
with the arm.
PROTRACTION
• moving a body part
forward toward or away
from the body’s midline,
such as pushing the
shoulders forward.

02
Bodymanagement skills:
• which involve balancing, maintaining equilibrium and postural control of the body in
stillness and in motion such as rolling, stopping, stretching, bending, twisting, landing,
climbing, and running.
Locomotor skills:
• which involve transporting the body in any direction from one point to another such as
walking, running, jumping, hopping, galloping, marching, and skipping.
03
Object control skills:
• require controlling implements and objects such as balls, hoops, bats, and ribbons that
involve the use of body parts, such as hands and feet.
Are particular set of skills that require the use of different body parts, such as feet, legs,
shoulders, body, head, arms, and hands. They are the foundation for more advanced and
specialized skills that learners will need to participate in various games, sports, and leisure
activities during their lives.

similar activities and will use identical
movement strategies to achieve success.
35.
Balance
• The capacityto sustain the body’s
line of gravity within the support
base with minimal postural sway.
Centering
• Your human body’s core, where all
body movements emanate and hold
you as you move together.
Center of Gravity
• The balance point or that point
where all the body’s weight is
distributed equally across all sides.
Posture
• The body’s presumed position either
with support during muscle activity
or a coordinated action by a group of
muscles working to maintain stability.
• provide a solid foundation for physical activities in any environment, which or without any
equipment. They can be introduced in simple, age-appropriate ways to help students improve their
movement’s efficiency and effectiveness. The application of these principles becomes more refined
as movement competence improves.
