W30-L7: Principles of Exercise Testing

Question 1

What is the Bruce Protocol?

Answer 1

Increasing Speed and difficulty of treadmill

Question 2

What is O2 pulse?

Answer 2

amount of oxygen per heart beat, VO2/HR which estimates stroke volume

Question 3

How can you test oxygen uptake?

Answer 3

different ways
to test through exercise, continuous
(ramp) or increase at time
intervals

Question 4

What is the lactate response in active groups?

Answer 4

Shifts to the right, takes longer to reach lactate threshold

Question 5

What are some indirect tests of fitness?

Answer 5

• Beep test

- PWC150/170 (power output to hit 150 HR and 170, as it goes up it implies you are fitter)

Question 6

What is endurance?

Answer 6

the ability to use a high proportion of your VO2 max, which is achieved by exercising at high VO2 without producing much lactate

Question 7

What is a better predictor of endurance than VO2 max?

Answer 7

cytochrome oxidase (ability of muscle to use O2/oxidative capacity)

Question 8

What is associated with a higher lactate threshold?

Answer 8

• longer time to fatigue

- lower the glycogen used (glycogen use as fuel causes fatigue)
