Energy Systems & Acute Response

Question 1

Heart Rate definition

Answer 1

The amount of time the heart beats per minute

Question 2

Stroke Volume definition

Answer 2

The amount of blood (mL) pumped from the left ventricle per beat

Question 3

Cardiac Output definition

Answer 3

SV x HR

Amount of blood pumped from the left ventricle per minute

Question 4

Tidal Volume definition

Answer 4

Amount of inspired and expired air per breath

Question 5

Respiratory Rate definition

Answer 5

Amount of breaths per minute

Question 6

Ventilation definition

Answer 6

TV x RR

Air breathed in and out per minute

Question 7

VO2 Max

Answer 7

Maximum amount of oxygen you can take up, transport and utilise

Question 8

Factors affecting VO2 Max

Answer 8

Age, gender & body size

Question 9

Benefits of higher VO2 max

Answer 9

Allows you to work at a higher intensity, for a longer period of time, AEROBICALLY

Question 10

Disadvantage of lower VO2 max

Answer 10

Fatigue quicker due to lactic acid build up with greater contribution from AG system than someone with a higher VO2 max.

Question 11

Acute response definition
