Oxygen consumption
9 important questions on Oxygen consumption
What is the definition of maximal oxygen utilization (VO2max)?
By which two groups of determinants, VO2max is limited?
Could the increase in stroke volume and heart rate frequency explain the maximal increase in oxygen consumption?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is CaO2-CvO2 and from what is it dependent?
Describe in your own words Fick's law.
Summarize all possible restrictions of oxygen diffusion from lung to blood
2. Limited ventilation
3. Limited bloodflow
4. Contact time of blood in the lungs
5. Ventilation/perfursion
6. Edema
7. Shunts
Which artificial methods can also enhance oxygen transport?
2. Additional blood volume
3. Higher levels of Hb (epo)
What are the restrictions of oxygen diffusion in the periphery?
2. Surface exchange
In highly trained athletes the VO2 max is constant over the whole season. However, the anaerobic threshold does shift as a consequence of the athletes shape. Define the anaerobic threshold and consider to which way this shifts when the athlete is in top shape.
