Acute and Chronic

Which of these is an acute musculoskeletal response?

• Hypertrophy

• Increased enzymes

• Increased blood supply

• Reduction in blood pressure

Hypertrophy of the heart takes place

• In the septum

• The Left Atrium

• The Aorta

• The left Ventricle

Hypertrophy Takes Place

• In the muscles

• In the heart and muscles

• In the heart, muscles and blood vessels

• All your musculoskeletal system

Hypertrophy is n

• Acute Response

• Chronic Response

A decrease in resting heart rate.... (2)

• Is an acute response

• Is a chronic response

• Happens because tidal volume increases meaning more air is passed in and out

• Happens because stroke volume and cardiac output go up as the heart gets more efficient

Which of these are acute responses? (3)

• Heart rate anticipatory rise

• Muscle fibre microtears

• Increased aerobic fitness

• Increased blood pressure

CARDIAC OUTPUT IS...

• The number of times the heart beats in one minute.
• The amount of blood ejected by the left ventricle per beat. 
• The amount of blood pumped out of the heart in one minute
• Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart. 

STROKE VOLUME IS...

• The amount of blood ejected by the left ventricle per beat. 
• The amount of blood pumped out of the heart in one minute
• The number of times the heart beats in one minute.
• The blood returning to the heart via the inferior and superior vena cava. 

HEART RATE IS...

• During exercise, blood flow is redirected away from the spleen, kidneys, guts and inactive muscles so that working muscles receive a greater % of Q.
• The number of times the heart beats in one minute.
• The blood returning to the heart via the inferior and superior vena cava. 

VASODIALATION IS...

• A increase in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
• A increase in the diameter of a blood vessel, resulting in a increase in blood flow to the area supplied by the blood vessel.
• A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
• A decrease in the diameter of a blood vessel, resulting in no change in blood flow to the area supplied by the blood vessel.
