Lab 6 - Anaerobic Threshold

Question 1

Determining the anaerobic threshold is a valuable measure for the assessment of: (2)

Answer 1

• training programs

- fitness levels

Question 2

For many years …….. was used as the main method.

Answer 2

VO2 max

Question 3

Problem with VO2 max test?

Answer 3

For the trained athlete, they will experience changes in their fitness level and performance without necessarily having improvements in VO2max.
- Thus, unreliable measure.

Question 4

What is anaerobic threshold?

Answer 4

the point during a graded exercise test where the rate of lactate production is greater than the rate of lactate removal within the muscle

Question 5

At what point, in mmol/L, does the anaerobic threshold usually occur?

Answer 5

Around 3-5 mmol/L

Question 6

2 calculations for determining the anaerobic threshold?

Answer 6

• 4 mmol/L method

- D-max method

Question 7

Lactate production is not responsible for causing muscle fatigue. What is?

Answer 7

• hydrogen ions

Question 8

How do hydrogen ions cause fatigue?

Answer 8

H+ ions inhibit the contractile properties of skeletal muscle, causing an increased work output and a resultant onset of fatigue.
