Question 1

Define lactate threshold and lactate turn point?

Answer 1

• The first point where lactate levels first start to rise above baseline
• Second break point – sudden and sustained increase in blood lactate

Question 2

What factors influence lactate levels?

Answer 2

• Depleted glycogen stores
• Muscle fiber composition
• Glycolytic and lipolytic enzyme activity
• Capillary and mitochondrial density
• Test design and data treatment
• Best fitting procedures
• Site of blood draw
• Analyser

Question 3

Why measure gross efficiency, what is it and why is it important?

Answer 3

• GE – measure of effective work. The amount of work completed relative to the amount of energy expended for each stage of the submaximal test.
• Valuable for assessing your adaptation to training
• Key determinant of endurance cycling performance
• A more efficient individual will be able to produce more power at a given metabolic rate / or produce a given power output at a lower metabolic rate

Question 4

What training adaptations occur on blood lactate?

Answer 4

• Downward and rightward shift of blood lactate curve
• Increase lactate removal and or decrease production
• Increased fat oxidation and or decrease cho oxidation
• Increase cardio respiratory fitness
• Increase peripheral adaptation

Question 5

What are the uses of the catapult tracking system?

Answer 5

• Assess the intensity of training sessions and matches
• Rehabilitation - Long term tracking can compare results during rehab to best results
• Track athletic performance
• Determine and quantify physiological demands of the game
• Prescribe more appropriate training
• Assess conditioning and physical preparation programs
• Ensure what was planned for session was achieved

Question 6

Name three things that can be measured using catapult?

Answer 6

• Duration
• Distance
• Velocity
• Player load
• Heart rate
• Repeated high intensity efforts
• Acceleration and deceleration

Question 7

Benefits of catapult tracking system

Answer 7

• Wireless / real time analysis with a 200m range
• Create time stamps for beginning and end of training drills or games which can be automatically applied to uploaded files
• Customize pitch or grounds by mapping player positions
• Synchronize GPS animations with videos

Question 8

What are the drawbacks of lab based fitness testing for team sport athletes?

Answer 8

• Time to complete for large teams
• Lack of specificity – particularly no turning
• Doesn’t replicate the intermittent demands of these sports

Question 9

What are the benefits of field testing?

Answer 9

• Multiple players
• Relatively short period of time
• Replicated demands of team sport
