What are the short term effect of exercise on the muscular skeletal system?

• •Increased production of synovial fluid

  •Increased range of movement in the joints

  •Micro tears in muscle fibres

  •Increased metabolic activity

• •Micro tears in muscle fibres

  •Increased metabolic activity

• •Increased heart rate

  •Increased metabolic activity

  •Sweating

  •Hypertrophy of the heart

• •Increased range of movement in the joints

  •Micro tears in muscle fibres

  •Hypertrophy of the heart

Synovial joints also contain a layer of cartilage surrounding the bone to protect the joint. Cartilage does not have a good blood supply so it relies on the synovial fluid by absorbing it to give it extra protection.

• True

• False

What is the correct term for tearing parts of your muscle fibres during exercise? (Not injury based)

• Muscle tear

• Strain

• Sprain

• Micro tears

Why do we get new bone formation after exercise?

Why does metabolic activity increase after exercise?

Why does heart rate increase during exercise?

• The muscles demand more oxygen so the heart beats faster

• Anticipatory adrenalin

• To meet demands of exercise

• You start to produce more blood

Sweat is produced...

• Cool the body down

• with no benefit to exercise

• To regulate the bodies temperature

• Lubricate your skin

When your body redirects blood by changing the size of its blood vessels. This is know as...

Lactic acid will start to build...

• During low intensity exercise

• During anaerobic exercise when the body cannot remove it quicker than you produce it

• When you work hard for 5 seconds

• When the body can remove it at a rate quicker than you can produce it

Cardiac output is...

• the amount of oxygen produced in a full exhalation

• the amount of oxygen produced in a full inhalation

• the amount of blood pumped in one beat

• the amount of blood pumped per minute by the heart
