Cardiorespiratory Adaptation Flashcards

Q

Best way to evaluate cardio respiratory capacity is through a __________

A

VO2 max test (Lab)

  • Measures how much O2 is used by the body
    – ml/O2/kg/min
  • Does NOT measure sport performance

Q

Why does aerobic performance improve with training? (identify 6 specific training adaptations in your answer)

A
  • Aerobic performance improves with training b/c of a combination of cardiovascular, respiratory, and others (muscle, metabolic, psychological) factors that adapt over time. Some of those being…
    1. Increased blood volume(Cardiovascular)
    1. ## Pulmonary Ventilation(respiratory)
    2. Cappilarization
    1. Lactate threshold(metabolic)
    1. Heart size
    1. -

Also important note:
– Maximal Oxygen Consumption (VO2 max)
– Increases with training

Cardiovascular adaptations
1. Blood volume
2. Capillarization
3. Heart size
4. Stroke volume
5. Heart rate
6. Cardiac output

Respiratory adaptations
1. Pulmonary Ventilation

muscle adaptations:
1. muscular endurance:
- Increased capillarization
* Easier access to blood
- Increased mitochondria
- increased myoglobin
- Increased oxidative enzymes

Metabolic adaptations
1. Lactate Threshold – Increases
* Improved “buffering” capacity by the liver
– Cori Cycle enzymes increase
* And, as aerobic system becomes more efficient, it can remain the predominant energy system longer, which means less lactate at low – moderate intensities

Psychological:
- motivation

3 CV
-
-
-
1 resp
-
2 other
