S1L6 Domains of Exercise

Question 1

What is Critical power and what does it require?

Answer 1

CP= the highest power output that can br maintained over time w/o fatiguing
requires homeostasis and high but steady state in:
* BLa conC
* VO2
* HR

Question 2

What is W’?

Answer 2

W’ = power x time
* overall power = power output - critical power
* represents anaerobic capacity

Question 3

What are the domains of exercise - and steady states

Answer 3

• low intensity –> below LT, BLa <2, <70%VO2max, steady state in <3 mins
• Moderate intesity –> between LT + MLSS, BLa 2-8mmol/L, 70-90% VO2max, steady state delayed
• Severe Intensity –> above MLSS / CP, BLa >2-8 mmol/L, >90% VO2max, steady state not attainable

Question 4

What are O2 uptake kinetics?

Answer 4

= breath by breath analysis of O2 uptake.

Question 5

What are the 3 phases of O2 uptake kinetics?

Answer 5

• Cardiodynamic component
• Primary component
• slow component

Question 6

what is phase 3?

Answer 6

= slow compenent. slight increase in values to an almost steady state
* only observed at a high poert output
