Methods/Overall
What is the investigation question?
What are the physiological responses that occur in response to anaerobic training for trained and untrained athletes?
Name all 3 physiological responses measured
Lactate acid levels, heart rate and ventilation rate
When did untrained athletes' ventilation peak in the shuttle test?
Near the end
Which group performed better overall across all tests?
Trained
In the lactate test, what were the starting km and ending km (excluding baseline)?
(+50 if you can specify running time per km)
Starting - 6km
Ending - 12km
Running time: 2 mins
TRUE or FALSE
Ventilation rate increases to deliver more oxygen during exercise
TRUE
Which participant displayed skewed/inaccurate results in the Lactate Acid test?
Participant D
What is human error?
Mistakes made by the participants or researchers that affect the results of an investigation
How many times was Wingate repeated?
(+50 if you can specify how many trained and untrained)
Wingate - 6 times (3 Trained & 3 Untrained)
What athlete category displayed the highest lactate level?
Which participant displayed the lowest resting heart rate in the Wingate test?
Participant B
What 3 contaminations could affect the investigation? (NAME ALL 3)
1. Participant training experience
2. Participant effort
3. Rest times between tests
Name TWO controlled variables
Possible answers:
1. The athletes (trained or untrained)
2. The environment/conditions
3. Equipment
4. Length of each sprint (25m)
What energy does anaerobic exercise use?
ATP-PC then anaerobic glycolysis (byproduct is lactate)
In the Wingate test, what does having a lower maximum heart rate mean/indicate
Trained athletes can perform at high intensity more efficiently due to adaptations
What TWO ways can affect the performance of each participant?
1. Differences in fitness level
2. Motivation and fatigue
Total number of laps for the shuttle test
6 laps
If not Lactate itself, what causes fatigue?
The accumulation of hydrogen Ions
In the shuttle test, which participant is Naman?
(+150 if you get it on the first try)
Participant B
Name ONE of the ways we could improve the investigation
Possible answers:
1. One person should perform the same role for all athletes across each experiment
2. The same trained and untrained individuals should be used for each experiment
3. Each athlete should also repeat the same test multiple times
4. All athletes complete the experiment at the exact same time
5. Equal encouragement and motivation throughout
