Lesson 19 · What the technology actually changes
Technology in training and performance
A runner improves by two per cent in a season, having changed shoes, changed track, added a GPS watch and completed another year of the same program. Four plausible causes arrived together, and the one that is not technology at all has the strongest claim of the four.
A distance runner improves their personal best by 2 per cent in a season. Over that season they changed to a new type of racing shoe, started training on a newly resurfaced track, began wearing a GPS watch that showed them their pace in real time, and did the same training program as the year before.
Write down how much of the improvement you would attribute to each of the four, and be specific about the fourth. Then answer the hard part: what evidence would you need to separate them, and is that evidence available to anyone?
- Distinguish training innovations, equipment advances and recording and monitoring, and say what each contributes.
- Explain the mechanism by which a specific technology improves performance, rather than asserting that it does.
- Weigh the limitations: validity, access and equity, over-reliance, privacy, and the regulatory line.
- Explain why it is genuinely difficult to attribute an improvement to a technology.
- Examine the role of technology, which means judging it rather than cataloguing it.
- Training innovation — a new method or tool that changes how training itself is delivered.
- Simulation — a reproduction of a competitive situation for training purposes, including virtual and augmented reality.
- Equipment advance — an improvement in the equipment used to perform, from footwear to surfaces to assistive devices.
- Assistive device — equipment that enables participation, such as a lightweight racing wheelchair or an audible ball.
- Global positioning system — satellite-based position tracking, used to record movement, speed and distance in training and competition.
- Wearable sensor — a device worn by the athlete that records movement, physiological or positional data.
- Training load — a quantified measure of the work an athlete has done, combining volume and intensity.
- Validity — whether a measure actually measures what it claims to.
- Reliability — whether a measure gives consistent results on repeated measurement.
- Technological doping — the claim that a piece of equipment confers an advantage large enough to be considered unfair.
The syllabus divides this dot point into three, and the division is useful because the three act on completely different parts of the performance.
| Category | Acts on | Examples | Route to improved performance |
|---|---|---|---|
| Training innovations | How training is delivered | Virtual and augmented reality simulation of game situations, altitude and environmental chambers, video-based opponent analysis, resisted and assisted training devices | More or better-targeted practice of the thing that matters, including repetitions that would be impossible, unsafe or too costly in the real setting |
| Equipment advances | The performance itself | Footwear, track and pool surfaces, bicycle and swimwear design, protective equipment, and assistive devices such as lightweight racing wheelchairs and audible balls | Directly changes the mechanics: less energy lost, less drag, more force returned, or participation made possible at all |
| Recording and monitoring | The information available to decide with | GPS units, heart rate monitors, sensor-enabled footwear, force platforms, video, athlete-management systems | Improves decisions rather than performance directly: what load to prescribe, when to rest, whether a change is working |
The third row is the one students most often get wrong, and getting it right is worth stating explicitly: monitoring technology does not improve performance. It improves decisions, and better decisions improve performance. A GPS unit does not make anyone faster. It tells a coach how much high-speed running a player did, which changes what the coach prescribes next — which is Lesson 10's evaluation and Lesson 15's monitoring with better instruments attached.
The assistive-device entry deserves a note too, because it is different in kind from the others. A lightweight racing wheelchair or an audible ball is not a marginal gain on an existing performance; it is the difference between competing and not competing. Technology that widens participation is the clearest case of technology improving sport, and it belongs in an answer about the role technology plays.
Ask what the technology acts on: the training, the performance, or the decision. Confusing the third with the second is the most common error in this dot point.
Quick check: A squad starts using GPS units in training. The most accurate description of how this improves performance is that it:
Equipment is the category that acts on the performance directly, so its mechanisms are biomechanical and follow straight from Lesson 17.
| Advance | Mechanism | Which Lesson 17 idea it uses |
|---|---|---|
| Footwear and track surfaces | Materials that return more of the energy stored on each foot strike, rather than dissipating it as heat, so less work is needed for the same speed | Efficiency: the cost of the task falls without the athlete changing |
| Swimwear, cycling position and clothing | Reduced drag through shaping, surface and fit | Fluid dynamics, where the benefit grows steeply with speed |
| Protective equipment | Spreads impact force over a larger area and a longer time, lowering peak force on the tissue | Force absorption, which is why it belongs in the injury discussion of Lessons 20 and 21 |
| Assistive devices | Lighter, better-fitted or better-shaped equipment, or equipment that supplies a cue through another sense | Force application and, most importantly, access to the activity at all |
Equipment is also where sport draws a regulatory line, and it draws it repeatedly because the line is not obvious. Governing bodies have restricted or banned equipment when they judged the advantage too large or too dependent on what an athlete could buy — full-body polyurethane swimsuits are the most-cited example, and footwear regulations in athletics are a more recent one. The phrase technological doping is used for advantages judged to have crossed that line.
The difficulty is that there is no principled place to put the line. All sport is played with equipment, and every generation's equipment is an advance on the last. Three questions are usually what a governing body is actually asking.
| Question | Why it matters |
|---|---|
| How large is the advantage? | A marginal gain is treated differently from one that rewrites the record book in a single season |
| Is it available to everyone? | An advantage available only to athletes with a particular sponsor or budget makes the contest a contest between suppliers |
| Does it change what the sport is testing? | If the equipment supplies the performance rather than the athlete, the sport is no longer measuring what it claims to |
That third question is the deepest one, and it is worth carrying into an answer because it explains why the debate never fully settles: sports disagree about what they are testing.
True or false: One reason governing bodies restrict some equipment is that an advantage available only to athletes with a particular sponsor or budget turns the contest into a contest between suppliers.
Monitoring technology has changed training more than any other category, because it made previously invisible things countable. A GPS unit records how far a player ran, how much of it was at high speed, how many accelerations they performed and where on the field. None of that was available to a coach twenty years ago at any price.
But it brings the failure mode Lesson 15 already identified, now with better instruments and a larger budget. Four limitations matter.
| Limitation | What it means | What to do about it |
|---|---|---|
| Validity and reliability | A device measures position or acceleration and then derives everything else through its own processing, which differs between products. Two brands can report different values for the same session | Use one system consistently and compare within it, never across systems; treat the trend as the data rather than the absolute number |
| Measuring what is easy | Distance and speed are easy to record; decision quality, skill execution and how an athlete feels are not, so training can drift towards what the system counts | Keep the cheap subjective measures of Lesson 15 alongside the expensive objective ones, because they see different things |
| Over-reliance | A number can override what a coach and athlete can plainly see. Data supports judgement; it does not replace it | Ask what decision the number changes, and what you would do if the device failed |
| Privacy and ownership | Physiological and location data is personal, and in professional sport it can affect selection and contracts. For school-age athletes, consent and who holds the data are real questions | Collect only what will be used, be explicit about who sees it, and secure informed consent from athletes and, for minors, their families |
The second row generalises into the single most useful sentence in this card: what gets measured gets managed, so measuring the wrong thing changes training in the wrong direction. A squad whose GPS reports total distance will tend to accumulate distance, whether or not distance is what their sport requires — which is a specificity failure from Lesson 6 caused by an instrument.
Keep the examples current
This is a fast-moving area and any specific product named in a textbook dates quickly. What does not date is the framework: which of the three categories the technology belongs to, what mechanism it acts through, and what its limitations are. Learn the framework and you can apply it to a device that does not exist yet.
Fill the gaps. Whether a measure actually measures what it claims to is called its , while whether it gives consistent results on repeated measurement is its . An equipment advantage judged large enough to be unfair is sometimes called technological .
Almost everything above assumes the technology is available. For most athletes it is not, and an examination of the role of technology that ignores access has examined only the top of the pyramid.
| Level | What is realistically available | What actually limits performance there |
|---|---|---|
| Professional | GPS for every athlete, force platforms, analysts, environmental chambers, simulation, sponsored equipment | Marginal gains, because the fundamentals are already maximised — which is exactly when a small technological advantage is worth pursuing |
| Representative or academy | Some shared GPS units, video, an athlete-management system, standard equipment | Consistency of training, load management across school and club commitments, and coaching quality |
| School and community | A phone camera, a free app, a heart rate strap, whatever equipment the family or club can afford | Sleep, fuelling, consistent attendance and basic coaching — none of which technology fixes |
Read the right-hand column upwards and the argument becomes clear. Technology gives the largest returns where the fundamentals are already maximised, and the smallest where they are not — which is the same hierarchy argument as Lesson 18 and the same opportunity-cost argument as Lesson 16, arriving for a third time. A school squad that buys GPS units before addressing session finish times has bought a measurement of a problem instead of a solution to it.
There is a real counterpoint, though, and a good answer includes it. Some technology has become dramatically cheaper: a phone camera does much of what a video analysis system used to, free apps record training loads, and a heart rate strap costs very little. So the access gap is narrowing for monitoring while it remains wide for equipment and simulation — and for assistive devices, cost is precisely what determines whether some athletes compete at all, which makes it an equity question rather than a performance one.
Odd one out. Three of these are limitations of monitoring technology. Which one is not?
The verb is examine, which means judging rather than cataloguing, and the hardest judgement in this dot point is causal: did the technology cause the improvement?
Card 01 is the general case. A runner improves by 2 per cent having changed shoes, changed surface, added a GPS watch, and completed another year of training. All four are plausible causes, they all happened at once, and the fourth — simply being a year further into a training program — is the one people forget, even though a year of training is the largest and most reliable of the four.
| Evidence | Can establish | Cannot establish |
|---|---|---|
| One athlete's improvement after adopting it | That the athlete improved | That the technology caused it, since everything else changed too, including a year of training |
| Many athletes improving after a technology becomes common | That something changed across the population, which is suggestive | Which of the several things that changed together was responsible; adoption is not random, since the best-resourced athletes adopt first |
| A controlled comparison of the same athletes with and without it | The size of the effect under those conditions, which is the strongest available evidence | Whether it transfers to competition, to other athletes, or over a season; and athletes usually know which condition they are in |
| A laboratory measure of energy cost or drag | That the mechanism is real and measurable | That the mechanical benefit becomes a competitive result, which depends on everything else in the race |
So a complete examine answer has a shape: name the category, give the mechanism, state what the evidence supports, name the limitations including access, and then judge — for whom, in what circumstances, and instead of what. That last clause is the one that separates an examination from a description.
Technology is a multiplier, not a substitute. It returns most where the fundamentals are already maximised, and least where they are not — which is where most athletes actually are.
Two truths and a lie. One of these statements is false. Find it.

A school sports program receives a one-off grant. The squad currently trains three evenings a week finishing at 9 pm, has one coach for 24 athletes, no monitoring of any kind, and a wide range of experience within the group. Four proposals are on the table.
| Proposal | What it would buy |
|---|---|
| A | GPS units for the whole squad, plus a subscription to the analysis platform |
| B | A second coach for two nights a week, and an earlier venue booking that moves the finish to 8 pm |
| C | New equipment for every athlete, of the type used at representative level |
| D | A phone tripod, a free video analysis app, heart rate straps, and a simple wellness and load record |
Answer five things. Rank the four and justify your top choice, referring explicitly to the hierarchy from Lesson 18 and to what actually limits performance at this level. For your top choice, what mechanism produces the improvement? Which proposal offers the most data for the least benefit, and why? What would you monitor to test whether your choice worked, and what could that monitoring not tell you? Finally, name one circumstance in which proposal A would become the right answer.
Lock it in. In one sentence, explain why monitoring technology returns more at professional level than at school level, even though the devices are identical.
Examine the role technology plays in improving athletic training and performance.
Examine asks you to inspect the role closely and bring out what it shows. It does not require a verdict, but the inspection must arrive at a point.
Plan: establish the categories, inspect each, then draw out what they show together.
Technology contributes in three distinct ways named by the syllabus: training innovations, equipment advances, and the recording and monitoring of training and performance. Each acts on a different link between training and outcome.
Training innovations change the stimulus itself. Altitude and heat chambers manipulate the environment to produce adaptations that would otherwise require relocation; anti-gravity treadmills allow running loads to be applied at reduced body weight during rehabilitation; and virtual and video-based decision training presents game situations repeatedly without the physical cost of playing them, so tactical exposure is decoupled from physical load.
Equipment advances change the efficiency or safety of the movement. Footwear and apparel reduce energy cost or drag, improved protective equipment reduces injury severity in contact sports, and prosthetic and adaptive equipment enables participation and competition that would otherwise be impossible — though advances that alter performance also raise questions of fairness and access, since the athletes who obtain them first are not distributed randomly.
Recording and monitoring change the information available for decisions. Global positioning and accelerometer systems quantify distance, speed and acceleration load in training and competition; heart rate and heart rate variability monitoring track internal load and recovery status; and video analysis provides objective technical and tactical review. This converts coaching decisions from impression to measurement, and allows load to be managed against a threshold rather than a feeling.
The inspection shows that technology's role is to increase precision rather than to replace the underlying training principles: it makes the stimulus more controllable, the movement more efficient and the response more visible, but it does not alter the fact that adaptation still requires an appropriate stimulus and adequate recovery. Its main risk is a data burden that exceeds the capacity to act on it, so that measurement substitutes for decision.

Its principal risk is a data burden exceeding the capacity to act on it, so that measurement substitutes for decision.
Assess the value of athlete monitoring technology for managing training load and preventing injury.
Assess requires a judgement of value against criteria. The stem names two purposes — load management and injury prevention — so the value may differ between them.
Plan: criteria, the case for, the case against, a verdict that discriminates, then a qualification.
Monitoring technology will be assessed against three criteria: whether it measures what actually matters to the athlete's response, whether its output reliably changes a training decision, and whether its cost — in money, time and athlete compliance — is proportionate to that benefit.
Against the first criterion the technology performs well. Global positioning and accelerometer systems quantify external load objectively, so a spike in acceleration or high-speed running volume — a known antecedent of soft tissue injury — is visible rather than inferred. Heart rate variability and sleep tracking give an indication of internal recovery status, and the data allows individualised load ceilings rather than squad-wide prescriptions. In elite settings this has genuinely shifted load management from retrospective to prospective.
Against the second and third criteria the value is weaker. External load is not internal load: two athletes covering identical distance experience different physiological stress, so the measure most reliably collected is not the one that matters most. Injury is multifactorial and individually variable, so monitoring shifts probabilities rather than predicting events, and a system implying prediction invites false confidence. Consumer-grade devices vary in accuracy, and the cost in equipment, analyst time and daily athlete compliance is substantial — while in most community settings there is no analyst to convert the data into a decision at all.
On balance the value is high for load management and considerably lower for injury prevention specifically. Monitoring reliably describes what an athlete has done and supports individualised prescription, which is a real and actionable benefit; it identifies elevated risk but cannot identify which athlete will be injured, so its contribution to prevention is probabilistic and easily overstated.
Value is also strongly setting-dependent: the same technology that supports a professional program with analytical support may produce, in a school or community club, data nobody has capacity to act on — in which case it consumes resources that basic load progression, sleep and recovery practices would have used more effectively.

Value is also setting-dependent — technology supporting a professional program with analytical staff may, in a school or community club, produce data nobody can act on, consuming resources that basic load progression, sleep and recovery practices would have used better.
Go back to card 01. The honest answer is that the four cannot be separated from this evidence, and the fourth — another year of the same training program — has the strongest claim of the four even though it is not technology at all. To separate them you would need the athlete's performance under each condition with the others held constant, which no single season can provide, and even a controlled comparison would not tell you whether the laboratory effect survives contact with a race. Write down whether you gave the fourth factor enough weight, and what you would say now if a coach told you a shoe had made an athlete faster.

📖 Comprehensive answers (click to reveal)
Multiple choice: 1 → C. 2 → B. 3 → A. 4 → D. 5 → B.
Activity 1, indicative answers: 1 → Training innovation. Mechanism: it supplies many more repetitions of the decision itself — reading a formation and choosing — than a training session could, without the physical load or the injury risk of live play, which is exactly the decision-under-constraint practice Lesson 10 argued for. Most serious limitation: transfer, since a simulated environment lacks the physical and emotional conditions of a real contest, so the decision practised may not be the decision the athlete has to make. 2 → Equipment advance. Mechanism: more of the energy stored on each foot strike is returned rather than dissipated as heat, so less muscular work is required for the same speed, which lowers the cost of the task in exactly the sense of Lesson 17. Most serious limitation: access and fairness, since the advantage may depend on what an athlete can buy or on their sponsor, which is one of the reasons governing bodies have regulated footwear. 3 → Recording and monitoring. Mechanism: it does not improve performance directly, but it makes training load, high-speed running and accelerations countable, so decisions about prescription and recovery are better informed. Most serious limitation: what gets measured gets managed, so a squad whose system reports total distance will tend to accumulate distance whether or not distance is what their sport demands; validity differences between systems and data privacy are also creditable. 4 → Equipment advance, and specifically an assistive device. Mechanism: it supplies through hearing the positional information a sighted athlete gets visually, so the athlete can locate and play the ball. Most serious limitation: cost and availability, which is what determines participation. It is different in kind because it does not deliver a marginal gain to an existing performance — it is the difference between competing and not competing, which makes it an equity issue rather than a performance one.
Activity 2, indicative answers: The defensible ranking is B, then D, then A, then C. Proposal B addresses the base of the hierarchy: moving the finish from 9 pm to 8 pm on three nights buys an earlier meal and an earlier lights-out, which is the largest recovery effect available and is being actively undermined by the current schedule; a second coach for 24 athletes with a wide experience range also fixes the constraint identified in Lessons 9 and 10, that supervision of a large group is necessarily intermittent and differentiation is what group sessions most need. The mechanism is therefore two-fold: more sleep produces better adaptation, better skill consolidation and lower injury risk, and a second coach produces more feedback per athlete and more appropriate practice structures. Proposal D is second because it is cheap, addresses the measurement gap with the tier-appropriate tools of Lesson 15, and leaves money for something else. Proposal A offers the most data for the least benefit: it would produce detailed load records for a squad whose actual limitation is a late finish and one coach, so it measures the problem rather than solving it, and it risks the "measured is managed" failure. Proposal C is last because representative-level equipment produces marginal gains at a level where the fundamentals are not yet maximised. Monitoring: reported sleep and lights-out time, a four-item wellness rating, and attendance, judged on trend before and after the change; it could not tell you which of the two components of proposal B produced any improvement, since both change at once, and it could not separate them from ordinary seasonal progression. Proposal A becomes right when the schedule, coaching and recovery are already sorted and the remaining question is genuinely about load distribution across a squad — that is, when the fundamentals are maximised and only marginal gains remain.
SA 1 (4 marks): Training innovation [1]: for example virtual or augmented reality simulation of game situations, or an altitude or environmental chamber — it acts on how training is delivered, supplying repetitions that would be impossible, unsafe or too costly in the real setting. Equipment advance [1]: for example footwear that returns more stored energy at foot strike, a resurfaced track, low-drag swimwear or a lightweight racing wheelchair — it acts on the performance itself, changing the mechanics directly. Recording and monitoring [1]: for example GPS units, heart rate monitors or sensor-enabled footwear — it acts on the information available to decide with. The fourth mark [1] for making the distinction explicit: monitoring technology does not improve performance directly, it improves decisions, and it is the decisions that then improve performance.
SA 2 (6 marks): Two marks each for three limitations, one for naming and one for explaining the consequence. Validity and reliability [2]: devices measure position or acceleration and then derive everything else through their own processing, which differs between products, so two systems can report different values for the same session and numbers cannot be compared across systems; the practical consequence is that a school must use one system consistently and read the trend rather than the absolute number. Measuring what is easy [2]: distance and speed are simple to record while decision quality, skill execution and how an athlete feels are not, so training drifts towards whatever the system counts; a squad whose units report total distance will accumulate distance regardless of whether their sport demands it, which is a specificity failure caused by an instrument. Privacy and consent [2]: physiological and location data is personal, and for athletes under 18 there are real questions about who holds it, who can see it and whether informed consent has been given by athletes and families; only data that will actually be used should be collected. Over-reliance and cost are equally creditable, the first because a number can override what a coach can plainly see, the second because the same money at this level buys coaching or an earlier finish, which have larger effects.
SA 3 (7 marks): Training innovations [1]: simulation, environmental chambers and video analysis change how training is delivered, supplying more or better-targeted repetitions of the thing that matters, including practice that would be unsafe or impossible live; the limitation is transfer, since the simulated environment lacks the physical and emotional conditions of competition. Equipment advances [2]: these act on the performance itself through mechanisms taken directly from biomechanics — energy return in footwear and surfaces lowering the cost of the task, reduced drag in swimwear and cycling, and force spread over a longer time in protective equipment [1]; they are also where sport draws a regulatory line, and governing bodies ask how large the advantage is, whether it is available to everyone, and whether it changes what the sport is testing — the last of which is why the debate never fully settles [1]. Recording and monitoring [2]: it makes previously invisible things countable and so improves decisions rather than performance directly [1], but it carries real limits: derived values differ between systems, easily counted things crowd out things that matter, a number can override visible judgement, and personal data raises consent and ownership questions, particularly for minors [1]. Access and equity [1]: technology returns most where the fundamentals are already maximised and least where they are not, which is where most athletes are — so a school squad that buys monitoring before fixing session times has measured a problem rather than solved it; against that, some monitoring has become very cheap, and for assistive devices such as racing wheelchairs and audible balls, cost determines whether an athlete competes at all, which is an equity question rather than a marginal-gains one. Attribution [1]: a single athlete's improvement after adopting a technology cannot establish that the technology caused it, because everything else changed too — including another year of training, which is typically the largest and most reliable factor of all; population-level improvement is suggestive but adoption is not random, and even a controlled comparison shows the effect under those conditions rather than in competition.
The framework is what to memorise, not the products. Which of the three categories does it belong to, what mechanism does it act through, what does the evidence support, what are its limitations including access, and for whom is it worth it instead of what? That structure applies to a device that has not been invented yet, which is the point of learning it rather than a list.
One idea carries beyond this lesson: what gets measured gets managed. It explains why monitoring changes training even when nobody intended it to, and it is worth remembering the next time a number becomes the goal. Lesson 20 turns to sporting injuries and their assessment.
