What this dot point is asking
QCAA wants you to treat training as an evidence-based process: collect valid and reliable data about the energy and fitness demands of a chosen activity, analyse it, use it to justify a training strategy, and then use further data to evaluate whether the strategy worked. This is the data thread that runs through the Unit 4 project (IA3) and the external exam. The marks come from handling data critically (validity, reliability, relationships) rather than just reporting numbers.
The answer
Primary and secondary data
- Primary data is collected first-hand for your specific purpose: fitness test results, GPS and heart-rate data from training, video analysis of movement, work-to-rest ratios timed during a game, and perceived exertion ratings.
- Secondary data is collected by others and reused: published fitness norms, sport-specific physiological profiles, governing-body match-demand studies, and training research.
A strong analysis combines both. Primary data describes this athlete in this activity; secondary data provides the benchmark and the explanation.
Validity and reliability
- Validity asks whether the data actually measures what it claims to. A beep test estimates aerobic capacity validly for a running sport but is a poor measure of swimming-specific endurance.
- Reliability asks whether the measurement is repeatable and consistent. Standardising the protocol (same equipment, time of day, instructions, and conditions) improves reliability.
Selecting tests that are both valid for the chosen activity and administered reliably is a marked skill, because invalid or unreliable data cannot support a sound training decision.
Analysing energy and fitness demands
To profile a chosen activity, students gather data on its movement demands and infer the energy-system contributions and fitness components. Timing work-to-rest ratios and intensities indicates the interplay of the ATP-PC, anaerobic glycolysis, and aerobic systems; mapping the actions indicates the priority fitness components. This analysis identifies the gap between the athlete's current capacities and the activity's demands, which the training strategy then targets.
Analysing relationships, not just totals
QCAA analysis is about relationships: how the data connect to performance and to each other. Compare an athlete's results against secondary norms, track change across a training block, and link a fitness limitation to an observed performance limitation. Identifying a trend or a relationship is worth more than reporting a single value.
Justifying a training strategy
The data justifies the strategy. If the analysis shows the activity is repeated-sprint dominant and the athlete fatigues late in a game, the data supports prioritising the ATP-PC and glycolytic systems and repeat-sprint training, justified by specificity. The justification should cite the specific data, not a general belief about the sport.
Evaluating effectiveness
After the training block, students reflect on primary and secondary data to evaluate the effectiveness of the strategy against the determined outcome. Re-test under the same conditions, compare pre and post results, and judge whether the energy and fitness requirements were better met and performance of the specialised movement sequences improved. A sound evaluation also notes confounders (illness, missed sessions) and the limits of the data.
Try this
Q1. Distinguish primary data from secondary data, giving one example of each in a training context. [2 marks]
- Cue. Primary data is first-hand (for example the athlete's own beep-test score); secondary data is reused from others (for example published aerobic-capacity norms for the sport).
Q2. Explain why validity and reliability both matter when selecting a fitness test, and describe one way to improve reliability. [4 marks]
- Cue. Validity ensures the test measures the relevant capacity for the chosen activity, reliability ensures the result is repeatable; reliability improves by standardising the protocol (same equipment, conditions, instructions, and time of day) so pre and post results are comparable.

2022 QCAA9 marksExplain how data collection during games analysis can assist with planning in the remaining features of an effective individualised training program.Show worked answer →
This is a 9 mark short response, marked in three strands worth 3 marks each. A high response explains, not just describes, how the data feeds each strand.
Specific training objectives (3 marks). Explain that games analysis data identifies an athlete's strengths and weaknesses in the relevant components of fitness, so the program can be tailored to improve weaknesses and maintain strengths. The data then lets the coach set and measure specific, individualised training objectives rather than generic goals.
Work volume, frequency, intensity and duration (3 marks). Explain that once objectives are set, the data is used to manipulate the work volume, frequency, intensity and duration of activities to target the identified components. For example, if the data shows the athlete must sustain submaximal work, the program lifts duration and frequency to suit, such as 70 per cent of maximum heart rate for 45 minutes.
Tapering and recovery (3 marks). Explain that the data gives individualised insight into tapering and recovery needs, indicating pre and post game recovery requirements and the tapering period that optimises competition performance.
Markers reward explaining a desired outcome for each strand, not just naming the feature.
2023 QCAA10 marksa) Describe two contributions fitness testing makes in developing athlete training programs. [4 marks] b) Demonstrate how the identified contributions in Question 12a) can be applied to specialised movement sequences in a position- or event-specific context of your choice. [6 marks]Show worked answer →
Part a) is worth 4 marks (two contributions, described, 2 marks each) and part b) is worth 6 marks for applying those contributions to a chosen context.
a) Two contributions (4 marks). Describe two clear contributions, such as: (i) fitness testing collects baseline primary data that diagnoses the athlete's current capacities and identifies the gap between those capacities and the activity's demands, which sets the training objectives; and (ii) re-testing under standardised conditions monitors change across the program, providing valid and reliable evidence of whether the strategy is working. Describing each contribution fully earns the 2 marks each.
b) Application to specialised movement sequences (6 marks). Choose a position or event (for example a netball goal attack) and demonstrate how each contribution shapes training of its specialised movement sequences. The baseline data might reveal limited repeat sprint capacity, so power and ATP-PC interval work is prioritised to support the explosive drive and shot; the monitoring data then confirms whether the sequence is performed with more force or accuracy after the block.
Markers reward a genuine, specific context and a clear link from the test data to the named movement sequences, not a generic description of testing.
