Time to get moving!

Time to get moving!

Physical activity is defined as any bodily movement produced by skeletal muscles that require energy expenditure. Physical activity includes exercise as well as other activities which involve bodily movement and are done as part of playing, working, active transportation, house chores and recreational activities. 

90% of stimulation and nutrition to the brain comes from the movement of the spine. This is why movement is important. This is not just in the form of traditional exercise. Think outside the box, playing with your kids, taking the stairs instead of a lift, 

Human movement is achieved by a complex and highly coordinated mechanical interaction between bones, muscles, ligaments and joint within the musculoskeletal system under the control of the nervous system.

Types of movement:

Flexion - Bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. 

Extension Straightening a joint. This occurs when the angle of a joint increases, for example, at the elbow when pointing a shot. 

Abduction - Movement away from the midline of the body. This occurs at the hip and shoulder joints during a jumping jack movement.

AdductionMovement towards the midline of the body. This occurs at the hip and shoulder, returning the arms and legs back to their original position from a jumping jack movement.

Rotation This is where the limb moves in a circle. This occurs at the shoulder joint during an overarm tennis serve. 

PlantarflexionPointing the toes, this movement only occurs at the ankle for example, pointing the toes in ballet. 

DorsiflextionThe foot moves towards the shin as if you are pulling your toes up. This movement only occurs at the ankle. 

This demonstrates how complex movement can be and why it is vital we have our joint movement checked regularly.
