BIOMECHANICS

Bio means

life

study of physical actions and forces

mechanics

Principles in Biomechanics:

1. Dynamics 2. static 3. kinematics 4. kinetics

study of moving systems that undergo acceleration and deceleration.

dynamics

study of system at equilibrium

static

whether at rest or moving at a constant velocity

static

study of motion patterns describes the effect of forces on a system

kinematics

including linear and angular variation of velocity through time, position and displacement.

kinematics

study of forces causing motion.

kinetics

Elements of Biomechanics:

1. motion 2. force 3. momentum 4. levers 5. balance

the movement of the body or an object across space

motion

are the major element of motion

speed and acceleration

the push or pull that causes a person or an object to accelerate, decelerate, stop or change direction.

force

the product of a weight and its velocity when it is moved.

momentum

our arms and legs function as__

lever

Lever parts:

1. resistance arm 2. fulcrum 3. axis of rotation

refers to stability

balance

The alignment of the body’s center of gravity over the base of support.

balance

Erect standing position with all body parts facing forward

anatomical reference

Considered the starting point for all body segment movements.

anatomical reference

Standing erect,with palms and feet facing forward

Anatomical Position

closer to head

superior

farther away to the head

inferior

toward the front

toward the back of the body

posterior

toward the midline of the body

medial

away from the midline of the body

lateral

closer to the trunk

proximal

away from the trunk

distal

toward the surface of the body

superficial

inside the body away from the surface

deep

Fixed lines of reference along which the body is often divided or sectioned to facilitate viewing of its structures

Anatomical Planes

Allow one to obtain a three-dimensional perspective by studying the body from different views

Anatomical Planes

The plane dividing the body into right and left portions

Sagittal plane

are names for the plane dividing the body into equal right and left halves

Midsagittal or median

dividing the body into equal right and left halves

Midsagittal or median

The plane dividing the body into front and back portions

Frontal/Coronal plane

The horizontal plane dividing the body into upper and lower portions

Transverse plane

Transverse plane aka

Horizontal plane.

have the fulcrum in the middle.

First class levers

have the load in the middle.

second class lever

Example in the body - Gastrocnemius causing plantar flexion at the ankle.

second class lever

Example in the body -Triceps causing Extension at the elbow

first class lever

have the effort in the middle.

third class lever

This means they can produce a large range of movement with relatively low effort.

3rd class lever

Example in the body - Bicep causing flexion at the elbow

3rd class lever

Movement where the body remains in place,but moves around its horizontal and vertical axes.

balance skills

The ability to neutralise forces that disturb equilibrium.

balance
