MATCH MOMENTS
A touch winger explodes into a 4-second chase. Which stored compound helps the ATP–PC system rapidly resynthesise ATP?
Phosphocreatine (PC or creatine phosphate) stored in muscle. It provides the phosphate needed to rapidly resynthesise adenosine triphosphate (ATP) during very short, intense movements.
What does the term stroke volume mean when describing the heart's response to exercise?
The volume of blood ejected by the left ventricle in one heartbeat, commonly measured in millilitres per beat (mL/beat).
What is active recovery between two demanding efforts?
Low-intensity movement, such as walking or easy jogging, performed between intense efforts to support recovery while remaining active.
What is the main purpose of a cool-down after a training session?
To reduce exercise intensity gradually, allowing heart rate and breathing to return toward resting levels and supporting the transition into recovery.
Game video shows 18 changes of direction over 6 minutes. What is the average number of changes of direction per minute?
18 ÷ 6 = 3 changes of direction per minute.
A volleyballer makes one explosive block, then walks slowly to the next position. Explain why the most important energy pathway changes between the actions.
The brief, maximal jump relies strongly on the fast ATP–PC system. During lower-intensity walking, the aerobic pathway makes a greater relative contribution to ATP resynthesis. All three energy systems continue operating, but their contributions change with intensity and duration.
A volleyball setter needs greater shoulder range of motion to prepare for an overhead set. Identify the fitness component and a suitable training method.
Flexibility is the component. A suitably designed flexibility program targeting shoulder mobility and range of motion may help; dynamic mobility exercises can also form part of the warm-up.
A coach plans 25 minutes of steady, uninterrupted running to improve aerobic capacity. Name the training method and explain its main purpose.
Continuous training. Sustained, relatively steady exercise without planned intervals is used to develop aerobic capacity and support the ability to continue submaximal work.
A touch team moves from general conditioning towards drills that closely match match-speed movement. Which phase of an annual plan is this most consistent with?
The pre-competition phase, when training generally becomes more specific to the demands of competition, while maintaining relevant fitness.
Footage shows that most rallies require several short lateral movements before an explosive jump. Explain ONE implication for a volleyballer's conditioning.
Training should include sport-specific lateral movement and explosive-jump tasks, with suitable work:recovery patterns, because they reflect the movement and energy demands observed in the footage. Specificity helps transfer fitness gains to performance.
A defender completes a demanding 30-second sequence of rapid shuffles, dives and jumps. Explain why the lactic acid system becomes increasingly important during the sequence.
High ATP demand continues after immediately available phosphocreatine begins to decline. Anaerobic glycolysis (the lactic acid system) uses muscle carbohydrate to resynthesise ATP rapidly without oxygen, resulting in lactate formation. ATP–PC and aerobic energy also contribute throughout.
A trained touch player sustains a faster running pace before blood lactate begins rising sharply. Identify the physiological measure that has most likely improved and explain its benefit.
Lactate threshold. The player can sustain a higher exercise intensity before lactate appearance outpaces removal markedly, supporting faster prolonged activity and repeat efforts across a match.
A circuit includes 30 seconds at each station followed by 15 seconds to recover. Calculate the work:rest ratio, then identify ONE variable the coach could adjust to increase the challenge safely.
30:15 simplifies to 2:1. The coach could progressively increase work time, reduce recovery, add a station or adjust exercise resistance/complexity, choosing one change appropriate to the athlete and monitoring form and fatigue.
In a four-week training block, running volume increases for three weeks and then decreases in week four. Suggest ONE sound reason for the lighter week.
The lighter week can provide planned recovery and allow adaptation after accumulated training load, lowering fatigue before further progression. The exact load should depend on athletes' responses and the program's goals.
A touch player completes six 10 m sprints. Their fastest is 1.9 s and slowest is 2.3 s. Calculate the time difference and explain what the pattern might suggest.
2.3 − 1.9 = 0.4 seconds. The difference may indicate reduced sprint consistency or fatigue across the six efforts, but causes require further information such as sprint order, rest intervals, surface and measurement reliability.
A touch player completes ten repetitions of 6 seconds of fast running followed by 24 seconds of easy jogging. Calculate the hard-work:active-recovery ratio and explain the aerobic system's role during the jogging.
6:24 simplifies to 1:4. The aerobic system contributes more during easy jogging and supports ongoing ATP supply and phosphocreatine resynthesis between hard efforts. Jogging is active recovery, not complete rest.
During a hard run, a player's heart rate is 168 beats/min and stroke volume is 105 mL/beat. Calculate cardiac output in litres per minute and state why this matters for performance.
Cardiac output = heart rate × stroke volume = 168 × 105 = 17,640 mL/min, or 17.64 L/min. Higher blood flow during exercise helps deliver oxygen and nutrients to working muscles and remove metabolic by-products.
A volleyballer wants more explosive jumping. Compare the likely usefulness of resistance training and a 40-minute easy run for this specific goal.
Appropriately programmed resistance training that develops lower-body force and power is more specific to explosive jumps; gradual progression and sufficient recovery are important. An easy run can support general aerobic fitness, but by itself does not directly target maximal jump power. Assess jump height and technique to monitor the outcome.
A player wants to increase speed and agility, but the coach puts maximal sprinting immediately after a very fatiguing circuit. Evaluate the session order and recommend a better approach.
Speed and agility demand high-quality, technically controlled movement. Fatigue from the circuit can reduce sprint quality and increase errors. After an appropriate warm-up, place the most demanding speed/agility work earlier in the session, then complete supplementary conditioning; allow adequate rest between fast repetitions.
After four weeks, volleyball jump height rises from 42 to 46 cm, but successful late-game blocks fall from 8 to 6. Evaluate the outcome using BOTH data sets.
The 4 cm increase indicates improved performance in the jump-height test. However, successful late-game blocks decreased by two, so improvement did not clearly transfer into the intended match outcome. Review positioning, timing, decision-making, fatigue and opponent difficulty; collect additional comparable match data before deciding whether to modify training.
A touch player's first 40 m sprint is 7.2 s but the final sprint is 8.1 s. The coach responds by prescribing only long, slow running. Evaluate that decision and justify ONE more specific training modification.
The 0.9-second decline is consistent with poorer late-game sprint performance, but the cause is not established by two times alone. Continuous aerobic work may help recovery capacity; however, it does not closely replicate repeated accelerations. Add progressively loaded, touch-specific sprint intervals with movement patterns and work:recovery periods informed by match footage. Re-test sprint consistency and consider sleep, fatigue and other causes.
A player's VO₂ max rises from 44 to 49 mL/kg/min after training, but repeated 10 m sprint times do not improve. Evaluate the results and justify ONE change to training.
The 5 mL/kg/min increase suggests improved aerobic capacity, but no improvement in repeated 10 m sprints means the training has not demonstrated better sprint performance. Maintain an appropriate aerobic component, then add progressive, short, high-intensity, sport-specific sprint work with suitable recovery. Assess the program using repeated-sprint times and match data; the test results alone do not prove causation.
A coach makes every touch player do the same maximal sprint interval session despite large differences in fitness, injuries and playing positions. Evaluate the decision and justify TWO changes.
A common drill may simplify organisation, but identical maximal loads ignore individuality and can compromise technique or recovery. First, adjust sprint number, intensity and recovery to the player's fitness and current readiness. Second, vary movement distances/directions and training focus to reflect positional game-analysis data (specificity). Progress loads gradually, monitor performance and adapt if fatigue or discomfort persists.
Design the key elements of a 70-minute touch-football training session for a player who repeatedly slows when defending late in games. Include warm-up, conditioning, recovery and ONE measurable outcome.
Example: 12-minute progressive RAMP warm-up; 15 minutes of defensive acceleration and change-of-direction skill; 25 minutes of appropriately progressed repeat-effort intervals reflecting game data (e.g. short intense efforts with controlled active recovery); 10 minutes of game-like defence under managed fatigue; 8-minute cool-down. Apply specificity and individuality, schedule adequate recovery between maximal efforts and track late-session sprint time or successful defensive recoveries. Adapt the work:recovery ratio to the player's measured demands and readiness.
Match analysis shows that a touch player makes 14 hard accelerations (about 5 s each), usually separated by 20–30 s of lower-intensity movement. After six weeks of easy continuous running, a shuttle test improves but late-game missed touches stay at 7. Devise and justify a more suitable training strategy using the evidence.
Retain some aerobic work because it supports sustained activity and recovery, but add progressive touch-specific repeat-acceleration intervals using approximately 5-second efforts and recovery informed by the observed 20–30-second pattern, with changes of direction and defensive positioning. Use individuality to adjust load and adequate rest to maintain skill quality. The improved shuttle result alone does not establish better defending; monitor sprint consistency plus missed touches in multiple comparable matches, and modify the strategy if the game outcome does not improve.
