As the race begins, what energy system would Clara use primarily?
- ATP-PC & anaerobic glycolytic systems (correct)
- oxidative phosphorylation system
- fatty acid system
- all of the above are used immediately and to the same level
The initial 2-4 minute period of exercise has been referred to as the:
The initial 2-4 minute period of exercise has been referred to as the:
- lactate threshold period
- oxygen debt period
- steady rate period
- oxygen deficit period (correct)
While warming up, Clara’s minute ventilation increases from 10 L/min to 40 L/min, based on the normal gas exchange response to exercise you would predict that:
While warming up, Clara’s minute ventilation increases from 10 L/min to 40 L/min, based on the normal gas exchange response to exercise you would predict that:
- Alveolar O2 must decrease
- Arterial-venous CO2 difference gets smaller
- Arterial CO2 is normal
- Alveolar CO2 must increase (correct)
- Venous CO2 decreases
