Fitness testing - Environmental training (97 cards)
What are the benefits of fitness testing?
Identify strengths and weaknesses
Enhance motivation
Monitor progress
Set goals and targets
Identify talent
Measure effectiveness of training programmes
What are the two methods of fitness testing?
Lab testing
Field testing
What is validity in sport?
Valid research is activity specific, it need to be relevant to performance
What is reliability in sport?
Reliable research uses a standardised environment and protocol
What can effect reliability?
Human error and technological error e.g. hand stop watches, different observers, different brands of heart rate monitors
What are the advantages of lab tests?
High levels of internal validity as controlling all the variables
What are the disadvantages of lab tests?
Low levels of ecological validity as not done in a natural environment
Often expensive equipment and trained scientist
What are the three fitness tests that can be done in a lab?
VO2 max treadmill test
Lactate threshold test
Wingate 30sec cycle test
What does a VO2 max treadmill test do?
Tells us the volume of oxygen a person can take in, transport and use per minute. Gives good measure of cardiovascular endurance/aerobic capacity
How should a VO2 max test be carried out?
Athlete connected to a gas analyser and HR monitor
Treadmill speed increased
Change in O2 and CO2 measured
Continues until athlete reaches exhaustion
Reached the aerobic limit - the higher the value the more efficient the body is at using O2
What is the lactate threshold test?
Exercise intensity at which the body starts to produce too much lactic acid in the blood. Useful for athletes who combine endurance and speed. Working at lactate threshold
How is the lactate threshold test done?
Athlete begins running at a fair pace
Treadmill speed increased at 3 minute intervals
Blood sample taken from finger or ear at each stage
Blood lactate levels measured to see at which intensity they reach a critical level - lactate threshold
What is a Wingate 30sec cycle test?
Measures anaerobic capacity. Ability to exercise effectively at a high intensity for a short period of time
How is a Wingate 30sec cycle test carried out?
Cycle ergometer set up with a resistance in proportion to athletes body weight
Athlete cycles at max effort for 30 secs
Number of revolutions counted every 5 secs
Results show average power over 30 secs, peak power achieved and fatigue index
What is fatigue index?
The difference between peak and low power in the set period of time
What are the advantages of field tests?
High ecological validity
Cheaper and more accessible
What are the disadvantages of field tests?
Low internal validity as limited control over variables
What is the goal of lab tests?
Direct measurement to specific components of fitness
What is the goal of field tests?
Predict scores using data from lab test results
What are the 10 different field tests?
Multistage fitness test
Harvard step test
Plank test
1 rep max
1 minute press-up test
Sit and reach test
Sprint tests
Vertical jump test
Illinois agility test
Stork stand test
What is the multi stage fitness test?
Test of aerobic capacity. Bleep test predicts a performers VO2 max
How is the multi stage fitness test performed?
20m distance marked out
Subject runs 20m shuttles in time to the beeps
Beeps progressively faster
Subject continues till exhaustion
Compared to normative tables and VO2 max value predicted
What is the Harvard step test?
Predicts VO2 max without performer working to exhaustion
Sub-maximal test
For ‘special populations’ e.g. elderly, obese
How is the Harvard step test carried out?
20 inch high step
Using a metronome the subject steps up and down at a rate of 30 steps per minute for 5 minutes
Heart rate measured between 1 and 1 1/2 minutes after - fitness index
Compared to normative table
