(4 cards)
1
Q
What are the RESPONSES to EXERCISE of the CV-SYSTEM?
A
- Increased Venous Return
- Vascular Shunting
- Increased Blood Pressure
- Increased HR
- Increased Cardiac Output
- Anticipatory Rise
- Increased TD
2
Q
Describe ANTICIPATORY RISE
A
- Increase in HR prior to exercise
- Due to release of Neurotransmitters & hormones (Noradrenaline and Adrenaline)
- Preps body for exercise
3
Q
What are the ADAPTATION of the CV-SYSTEM?
A
- Cardiac Hypertrophy
- Increased Blood Volume
- Capillarisation of Skeletal Muscle
- Increase in resting and exercising SV
- Reduction in resting BP
- Decrease in resting HR (Bradycardia)
- Decrease in HR Recovery Time
4
Q
Define BRADYCARDIA
A
Resting HR below 60bpm
