Q

How do joints demonstrate varying levels of stability and mobility?

A

Depending on their function they tend to favour one over the other.

Lumbar spine has some mobility [15° of rotation] but most stability

Thoracic spine is more mobile

Scapulothoracic joint is more stable and provide solid platform for pulling and pushing

The stability of the foot is unique because it varies during the gait cycle. Stable at push off and mobile at pronation

Q

What is used when people work at hard intensities for a few minutes?

A

They use carbohydrates stores via the glycolytic and anaerobic system which produces ATP without oxygen

E.g. high intensity intervals lasting 1 to 2 minutes with a recovery to breath oxygen and replenish the muscles

Q

What is used when people work at moderate and low intensities for longer than a few minutes?

A

A combination of carbohydrates and fats are used with oxygen to produce ATP via the aerobic system.

E.g. swimming, cardio classes and step classes

40
Q

What important information should an instructor know about muscles and joints?

A

They should know where a muscle is located and what joints it crosses

Muscles in the anterior/front are used for pushing, muscles in the posterior/back are used for pulling

41
Q

What is joint flexion?

A

When the angle between any two bones decreases, results from a muscle pulling on its attachments and shortening

42
Q

What is joint extension

A

When the angle between joints increases, the muscle on the flexion side lengthens while the opposing muscle pulls and shortens

What is hyperflexion?

A

When a part of the body is flexed beyond its normal range of motion

44
Q

What does neutral posture mean?

A

That all of the muscles work on the body’s centre equally

An equal amount of static, isometric tension on the anterior and posterior muscles of the core

Natural relationship between the ribs and hips where there’s no exaggeration in either direction

45
Q

What is an unique aspect of the trunk of the body?

It functions as the tunnel through which all systems connect

46
Q

What is the centre of the core?

A

Pelvic floor

47
Q

Which muscles protect the core?

A

The transverse abdominus compresses and protects the core and stabilizes the spine

48
Q

What is one way to describe the function of the transverse abdominis?
