Lecture 7 - Measuring Workload in Team Sports Flashcards
What are the 4 common ways of measuring workload in team sports?
External Load (what they do) Internal Load (physiological/psychological) Fatigue (how do they cope with it) Preparedness (are they ready to train/play)
What is the difference between efficacy and effectiveness?
Efficacy -> ability to produce a desired/intended result
Effectiveness -> degree to which something is successful in producing the desired outcome
Why is GPS tracking used often to measure for workload?
Efficacious way of improving sports performance
Measures how fast/far an athlete moves during a game
Used for small populations
What is good about sRPE?
Simple/effective
Good efficacy but not as effective
What is the relationship between fitness and fatigue?
Stimulus applied -> fatigue response -> player then adapts accordingly
What is the IOC consensus on player load?
Sporting and non-sporting burden as a stimulus applied to our biological system
What is validity?
Agreement between value of measurement and its true value
What are some internal measures of workload?
How are they valid?
RPE, sRPE, HR, Blood Lactate, Sleep
Physiological responses to external loads
sRPE - differences between the numbers and words
What are some external measures of workload?
How are they valid?
Power output, speed, neuromuscular function
Easy to validate
High speed running = velocity above a certain level
What is the relationship between HR and exertion in terms of sRPE?
Exponential increase in HR with exertion
Difference between very hard and maximal is only 3
Removing the numbers is better to reduce bias
What are the 2 different types of training load?
Acute = work in a 7-day period = short-term response
Chronic = average of last 4 weeks = long term adaptations
If you do less than your chronic load your fitness lowers
What were some of the findings of the Gabbett paper? (training load and injuries)
More you train should get fitter - but increase injury risk
Low training = low injuries
Team sports = high fitness and low injury levels
What are some of the findings of the Gabbett paper? (acute and chronic load)
What is the sweet spot for the ratio between acute and chronic load
Acute:Chronic ratio - injury likelihood is a %
Acute = 2x higher than chronic (15% of injuries)
Low load = reduced injury likelihood
Sweet spot = 0.8-1.3 ratio
What did the dots mean on Weaving study?
higher = higher skill level lower = higher speed level
What were the findings of Sawczuk? (player load on well-being)
What was the only factor influencing well-being?
Session duration the biggest weighing factor for load
Increased load = well-being not influenced but recovery reduced
Lower load = well-being was different
Sleep
