3. Movements
• Movements occurs in a direction called "plane"
and with a support called "axis"
• There are 3 varieties.
• 1. Sagittal plane with frontal axis
• 2. Frontal plane with Sagittal axis
• 3. Transverse plane with longitudinal axis
• Note: Usually avoid the longitudinal plane and
transverse axis to prevent damage to the smallest
joints like vertebral column.

4. Axes and Planes

5. Movements
• Flexion: forward movement (except knee)
• Extension: backward movement (except knee)
• Adduction: movement towards the midline of the
body
• Abduction: Movement away from midline
• Medial rotation: turning inward
• Lateral rotation: turning outward
• Pronation: pledge position of fore-arm
• Supination: showing position of fore-arm

7. Newton’s Laws of motion in Physics
Law-1: A body at rest (Samasthiti) and a constant motion will
remain in motion until getting an interruption (instructions to
start and stop)
Law-2: The force acting on an object is equal to the mass of
that object times, its acceleration. F=ma. Ability to move from
samasthiti to final pose and then reversing after holding.
Law-3: For every action, there is an equal and opposite
reaction (ability of preventing fall is the reaction from
opposite side of the body). It is immediate or situational
called momentum (instinct or reflex)

9. Internal force of Kinetics
• Internal forces are given under muscle
physiology, angle of pull, levers.
• Mind is the interaction between learned or
perceived information (sensory & motor
organs) to the memory (corpus callosum,
temporal cortex)

12. Angle of pull

13. As per the muscle pull. The joint movement
happens called Proprioception.
Lever is that, usage of muscles at an angle
reduces the mechanical load or energy
consumption.

20. Goniometer

24. • Mannual & mechanical Support: Teacher’s
support for performing asana or usage of
belts, bolsters, blocks, wall are external
supports.
• Even gripping hands is support for maintain
final posture. Supports are considered to be
neuton’s 3rd law. There is no “Sthiram
Sukham” without gripping.
