Unit 4 - AOS 3 - Chronic Adaptations Flashcards

1
Q

Name Aerobic Cardiovascular chronic adaptations

A
  • Increased left ventricle size and volume
  • Increased capillarisation of heart muscle
  • Increased stroke volume
  • Decreased resting and submax HR and faster recovery HR
  • Decreased HR during submax workloads
  • Increased Cardiac output at Max intensity
  • Decreased blood pressure
  • Increased Blood Volume (plasma, RBC)
  • Increased LIP
  • Increased Arterio-venous oxygen Difference

Q

Aerobic - Cardiac Hypertrophy

A

Cardiovascular
- Increased size of left ventricular cavity
-> Increase volume of blood which can enter heat

Q

Aerobic - Capillary density

A

Cardiovascular
- Increase in amount of capillaries in heart itself
-> increases blood flow

Q

Aerobic - Cardiac Output (Max intensity)

A

Cardiovascular
- volume of blood pumped by the heart per min (HR x SV)
->Any increases in the Cardiac output at maximal intensity are due to an increase in Heart rate as the stroke volume has reached its filling capacity of the heart after submax. Increases blood flow.

Q

What is the combined aerobic chronic adaptation?

A

Increased Maximum oxygen uptake (VO2 max)
= “The volume of oxygen consumed, transported and utilised by body per ml/min/kg.
