Midterm Part 3

Question 1

What are the 3 factors for endurance performance?

Answer 1

-VO2 max
-Lactate Threshold (Fractional utilization)
- Economy
Bonus: Strategy/pacing

Question 2

What are the 4 criteria for VO2 max achievement?

Answer 2

• Volitional Exhaustion
• Peak RER greater than 1.1
• Peak & Plateau of VO2 (no change greater than 100ml)
• Age predicted or known HR max is reached

Question 3

VO2 max is a measure of what?

Answer 3

POWER (RATE) not Volume

Question 4

Is VO2 better at measuring between people or between groups?

Answer 4

Between groups, for instance between Tennis players and Hockey players, rather than just between hockey players.

Question 5

What is the difference between Absolute and Relative VO2?

Answer 5

Absolute: L/Min -> for non weight bearing sports such as cycling, swimming
Relative: ml/kg/min -> for weight bearing sports such as running, skiing etc

Question 6

If specificity is so important why do we not just train for our event?

Answer 6

Because adaptation does not come without overload, one needs to balance between specificity and overload in order to maximize training adaptations.

Question 7

Describe LSD training (6)

Answer 7

• Low to moderate intensity (50-70% VO2)
• 70% of HR max
• 75-80% of AT intensity
• 15-20 ppm below HR @ threshold
• 70-75% of race pace for endurance athletes
• Long duration (45min+)

Question 8

Purpose of LSD training?

Answer 8

• Extend distance
• extend endurance time
• improve efficiency
• recover from hard training
• Physiological effects: enhance fat utilization, caloric expenditure, build muscle endurance
