The mock paper is designed to mirror the WJEC Unit 3 assessment format. It consists of three sections: Section A contains multiple‑choice and short‑answer questions testing breadth of knowledge; Section B presents data‑response and applied scenario questions; Section C requires an extended synoptic essay. Mark allocations range from 1 mark for factual recall to 20 marks for the essay, with a total of 80 marks in 2 hours.
模拟卷仿照 WJEC 单元 3 的评估格式设计。共三个部分：Section A 为选择题和简答题，考查知识广度；Section B 为数据分析和应用情境题；Section C 要求撰写一篇综合性小论文。分值从考查事实性回忆的 1 分题到 20 分的小论文不等，全卷 80 分，考试时间 2 小时。
Topics are drawn directly from the specification content: energy systems, training principles, arousal theories, feedback in learning, media and commercialisation, and diet‑performance links. The paper rewards precise terminology, applied examples, and the ability to link physiological and psychological concepts.
试题直接取材于考纲内容：能量系统、训练原则、唤醒理论、学习中的反馈、媒体与商业化以及饮食与表现的关系。阅卷看重术语的准确性、应用实例以及关联生理学与心理学概念的能力。
2. Energy Systems and Recovery MCQ Breakdown | 能量系统与恢复选择题解析
Question: During a 400‑metre sprint, which energy system provides the majority of ATP resynthesis after the first 10 seconds?
A. ATP‑PC system
B. Anaerobic glycolytic system
C. Aerobic system
D. Beta‑oxidation system
题目：在 400 米短跑中，前 10 秒后主要由哪个能量系统提供 ATP 再合成？
A. ATP‑PC 系统
B. 无氧糖酵解系统
C. 有氧系统
D. β‑氧化系统
Answer: B – Anaerobic glycolytic system. The ATP‑PC stores are largely depleted within 8–10 seconds of maximal effort. For the remainder of a 45–60 second 400‑m run, the anaerobic glycolytic system (lactic acid system) becomes the dominant provider, breaking down glycogen without oxygen to produce ATP rapidly, though with the by‑product lactic acid.
答案：B – 无氧糖酵解系统。ATP‑PC 储存在最大强度运动 8–10 秒后即大幅消耗。在持续 45–60 秒的 400 米跑剩余时间里，无氧糖酵解系统（乳酸系统）成为主导，在无氧条件下分解糖原快速产生 ATP，同时副产乳酸。
Many students incorrectly select A, forgetting the time‑course of the ATP‑PC system. Note that the aerobic system contributes only minimally in such a short, high‑intensity event, and beta‑oxidation is the breakdown of fats, irrelevant here.
很多学生误选 A，忽略了 ATP‑PC 系统的时间进程。需注意在如此短暂的高强度项目中，有氧系统贡献极小，而 β‑氧化是脂肪分解，与此无关。
3. Short‑Answer: Principles of Training | 简答题：训练原则
Question (4 marks): Explain the principle of progressive overload and give a specific example of how a netball centre player could apply it to improve cardiovascular endurance.
题目（4 分）：解释渐进超负荷原则，并给出一个具体的例子，说明一名无挡板篮球中锋球员如何运用该原则改善心血管耐力。
Model answer: Progressive overload is the gradual increase in training stress so the body continues to adapt without injury or overtraining. For a netball centre, one method is to increase the duration of continuous running sessions by 10% each week. For instance, starting with a 20‑minute run in week 1, progressing to 22 minutes in week 2, while maintaining the same intensity. This challenges the aerobic system and stimulates improvements in stroke volume, capillarisation and VO₂ max.
参考答案：渐进超负荷是指逐步增加训练负荷，使身体在不断适应中避免受伤或过度训练。对无挡板篮球中锋而言，一种方法是将持续跑步课的时长每周增加 10%。例如，第一周从 20 分钟跑开始，第二周进展到 22 分钟，同时保持同等强度。这会挑战有氧系统，刺激每搏输出量、毛细血管化和 VO₂max 的提升。
Mark‑scheme tips: award 1 mark for defining progressive overload, 2 marks for a relevant, specific example with quantification, and 1 mark for linking to a physiological adaptation. Avoid vague statements such as ‘train harder’.
评分要点：定义渐进超负荷得 1 分，给出量化、具体的相关例子得 2 分，联系一种生理适应得 1 分。避免“练得更猛”等笼统表述。
4. Sport Psychology: Arousal and Performance | 运动心理学：唤醒与表现
Question (6 marks): Using the Inverted‑U theory, explain why a golfer might underperform when attempting a crucial 2‑foot putt in a major championship. Suggest a cognitive technique the golfer could use to manage arousal.
题目（6 分）：运用倒 U 型理论，解释为什么高尔夫球手在大赛关键时刻推 2 英尺推杆时可能表现失常，并提出一项可用于调控唤醒水平的认知技术。
Model answer: The Inverted‑U theory states that as arousal increases, performance improves up to an optimal point, beyond which further arousal leads to deterioration. A 2‑foot putt requires fine motor control and precision – skills that thrive at low‑to‑moderate arousal. The pressure of a major championship can push the golfer into an over‑aroused state, causing muscle tension, narrowed attention and rushed stroke execution, resulting in a miss.
参考答案：倒 U 型理论指出，随着唤醒水平升高，运动表现提高，直至达到最佳点，超过此点后表现下降。2 英尺推杆需要精细运动控制和精准度——这些技能在低至中等唤醒水平下表现最佳。大赛压力可能将球员推入过度唤醒状态，导致肌肉紧张、注意窄化和仓促挥杆，最终错失推杆。
A cognitive technique such as visualisation can help: the golfer mentally rehearses a smooth, successful putt, focusing on tempo and target, which diverts attention from outcome pressure and lowers arousal towards the optimal zone. Alternative techniques include self‑talk (‘smooth stroke’) and deep breathing.
可采用视觉化等认知技术：球员在脑海中演练一次流畅成功的推杆，专注于节奏和目标，将注意力从结果压力转移，使唤醒降至最佳区间。其他方法包括自我对话（“平稳推杆”）和深呼吸。
5. Data Interpretation: Heart Rate and Recovery | 数据分析：心率与恢复
Question (8 marks): The table below shows the heart rate of a 17‑year‑old hockey player immediately after a Yo‑Yo intermittent recovery test and at 1‑minute intervals during recovery. Examine the data and explain the physiological mechanisms responsible for heart rate recovery. (Data: Post‑test HR = 198 bpm; after 1 min = 172 bpm; after 2 min = 148 bpm; after 3 min = 128 bpm.)
题目（8 分）：下表显示一名 17 岁曲棍球运动员在 Yo‑Yo 间歇恢复测试后即刻，以及恢复期每分钟间隔的心率。审视数据并解释心率恢复背后的生理机制。（数据：测试后即刻心率 = 198 bpm；1 分钟后 = 172 bpm；2 分钟后 = 148 bpm；3 分钟后 = 128 bpm。）
Analysis: The heart rate drops from 198 to 128 bpm in 3 minutes, indicating good recovery fitness. The fast initial drop (26 bpm in the first minute) reflects the rapid restoration of ATP and PC stores and the clearance of metabolic by‑products via the parasympathetic nervous system reactivation. The continued decline owes to the repayment of oxygen debt – the excess post‑exercise oxygen consumption (EPOC) – which supports the removal of lactate, replenishment of glycogen, and restoration of body temperature.
解析：心率在 3 分钟内从 198 降至 128 bpm，表明恢复能力良好。首分钟的快速下降（26 bpm）反映出 ATP 和 PC 储备的迅速恢复，以及副交感神经系统的重新激活对代谢副产物的清除。后续持续下降归因于氧债的偿还——运动后过量氧耗 (EPOC)——它支持乳酸清除、糖原再合成和体温恢复。
A student scoring full marks would define EPOC, mention the fast and slow components, and link heart rate decline to cardiac control centres (medulla oblongata, sympathetic withdrawal, vagal tone increase). The data supports a trained individual; an untrained person would show a slower, flatter recovery curve.
满分答案应定义 EPOC，提及快慢两个阶段，并将心率下降与心脏调控中枢（延髓、交感神经撤除、迷走张力增强）联系起来。数据支持这是一名具备良好训练背景的人；未经训练者则表现为较慢、较平缓的恢复曲线。
6. Skill Acquisition: Feedback Types | 技能习得：反馈类型
Question (5 marks): Compare the effectiveness of intrinsic and extrinsic feedback for a novice gymnast learning a forward roll on the floor.
题目（5 分）：比较内在反馈和外在反馈对初学者学习地板前滚翻的有效性。
Model answer: Intrinsic feedback is sensory information arising from the movement itself – kinaesthetic sensation, vestibular awareness, and visual input. For a novice, intrinsic feedback is often unreliable because the correct ‘feel’ of the skill has not yet been established. Extrinsic feedback (augmented feedback) provided by a coach, such as verbal cues (‘tuck your chin’) or video replay, is more effective early on because it directs the learner’s attention to critical aspects and corrects errors before bad habits form.
参考答案：内在反馈是动作本身产生的感觉信息——动觉感受、前庭意识和视觉输入。对初学者而言，内在反馈往往不可靠，因为尚未建立该技能的正确“感觉”。教练提供的外在反馈（增强反馈），如口头提示（“收下巴”）或视频回放，在初期更有效，因为它能将学习者的注意力引导至关键环节，并在坏习惯形成前纠正错误。
However, over‑reliance on extrinsic feedback can inhibit the development of error‑detection mechanisms, so a coach should gradually reduce its frequency, shifting the learner towards intrinsic feedback in the associative stage. The comparison should mention the stages of learning.
然而，过度依赖外在反馈会抑制错误觉察机制的发展，因此教练应逐渐降低反馈频率，在动作联结阶段将学习者引向内在反馈。比较时需提及学习阶段。
7. Socio‑Cultural: Commercialisation of Sport | 体育与社会：体育商业化
Question (10 marks): Evaluate the positive and negative impacts of television broadcasting rights on the commercialisation of professional football.
题目（10 分）：评估电视转播权对职业足球商业化带来的正面与负面影响。
Positive impacts: Broadcasting rights generate huge revenue, enabling clubs to invest in facilities, youth academies, and elite players, raising the standard of the sport. Global coverage increases spectator numbers, attracts multi‑national sponsors, and creates a year‑round spectacle that boosts related industries (merchandising, tourism). The Premier League’s overseas rights, for example, account for over half of its total media income.
正面影响：转播权带来巨大收入，使俱乐部得以投资于设施、青训学院和精英球员，提升竞技水平。全球转播扩大观众群，吸引跨国赞助商，创造全年不间断的盛况，并带动相关产业（商品销售、旅游业）。例如，英超的海外转播收入占其媒体总收入的半数以上。
Negative impacts: The need to accommodate TV schedules fragments match days, inconveniences fans, and can compromise player welfare through congested fixtures. Commercial priorities may overshadow sporting integrity, with kick‑off times moved for maximal viewership. Smaller clubs without a large broadcast appeal can struggle to compete, widening the financial gap. Over‑commercialisation can also alienate traditional fans who feel the game has become a business.
负面影响：为满足电视转播安排，比赛日被打散，给球迷带来不便，密集赛程也可能损害球员福利。商业利益可能凌驾于体育公正之上，开球时间因收视率而调整。转播吸引力不足的小俱乐部难以竞争，财务差距拉大。过度商业化还可能疏远传统球迷，让他们感觉比赛已沦为生意。
Top‑level answers will link to concepts like the ‘golden triangle’ (sport–media–sponsorship) and discuss the balance between commercial success and preserving sporting values.
高层次的答案会联系到“金三角”（体育—媒体—赞助）等概念，并探讨商业成功与守护体育价值之间的平衡。
8. Synoptic Question: Diet and Endurance Performance | 综合题：饮食与耐力表现
Question (12 marks): Explain how carbohydrate loading can benefit a marathon runner, referring to energy system interplay and potential drawbacks.
题目（12 分）：解释碳水化合物负荷如何有利于马拉松运动员，结合能量系统交互作用并说明潜在缺点。
Explanation: Carbohydrate loading aims to maximise muscle and liver glycogen stores before prolonged endurance events (>90 min). A runner typically tapers training while increasing carbohydrate intake to ~8–10 g per kg body mass over 2–3 days. During the marathon, the aerobic system predominates, relying on glycogen and fat as fuels. Elevated glycogen stores delay the onset of fatigue – ‘hitting the wall’ – by sustaining glycolysis and the Krebs cycle for longer, preserving blood glucose for the brain.
解释：碳水化合物负荷旨在长时间耐力项目（>90 分钟）前最大化肌肉和肝脏的糖原储备。跑者通常在赛前 2–3 天减量训练，同时将碳水化合物摄入提高至约 8–10 g/kg 体重。马拉松期间，有氧系统占主导，依赖糖原和脂肪供能。提高的糖原储备通过延长糖酵解和克雷布斯循环的工作时间，延缓“撞墙”现象出现，从而为大脑保持血糖供应。
Potential drawbacks: The loading phase can cause water retention (each gram of glycogen stores ~3 g of water), leading to a feeling of heaviness and stiffness. Some athletes experience gastrointestinal discomfort from high‑fibre carb sources. Additionally, if not combined with adequate hydration, performance may still suffer. Psychologically, an over‑emphasis on carb loading can cause anxiety if the regimen is disrupted.
潜在缺点：负荷期间可能导致水潴留（每克糖原储存约 3 克水），引起沉重和僵硬感。某些运动员摄入高纤维碳水来源可能出现胃肠不适。此外，若未配合充足补水，表现仍会受影响。心理上，过度强调碳水负荷一旦被打断还可能引发焦虑。
Synoptic links must be made to the aerobic energy system, the role of insulin and glucagon, and the concept of glycogen sparing. A developed answer will note that carb loading is most effective alongside a strategy of in‑race carbohydrate feeding and hydration.
必须综合关联有氧能量系统、胰岛素与胰高血糖素的作用，以及糖原节省概念。一份成熟的答案会指出碳水负荷最有效的方式是与赛中补糖和补水策略相结合。
9. Common Mistakes and High‑Scoring Tips | 常见错误与高分技巧
Mistake 1 – Vague, non‑specific examples. Saying ‘a footballer needs progressive overload’ without specifying how (e.g., increasing squat resistance by 5% weekly) fails to earn application marks. Always quantify or name a concrete exercise.
错误 1 – 例子笼统、不具体。只说“足球运动员需要渐进超负荷”而不明确方式（例如每周增加深蹲负重 5%），无法获得应用分。始终要量化或写出具体训练手段。
Mistake 2 – Confusing energy system time frames. Mixing up ATP‑PC and glycolytic duration is a frequent error. Memorise: ATP‑PC 0–10 s, glycolytic 10–60 s, aerobic 60 s+. Use these cut‑offs when analysing intensity and duration of activities.
错误 2 – 混淆能量系统时间范围。混淆 ATP‑PC 与糖酵解系统的时间是常见错误。牢记：ATP‑PC 0–10 秒，糖酵解 10–60 秒，有氧 60 秒以上。分析活动强度和持续时间时应用这些分界点。
Mistake 3 – Describing theories without application. When asked about arousal theories, simply restating the Inverted‑U or Catastrophe model without applying it to the specific sport or situation limits marks to a basic level. Always follow description with ‘therefore, in this scenario…’.
错误 3 – 只描述理论而不应用。当被问及唤醒理论时，单纯复述倒 U 型或突变模型却不将其应用于具体运动或情境，得分会限于基础层次。始终在描述后接续“因而在此情况下…”。
High‑scoring tip: Use technical language accurately (e.g., ‘parasympathetic reactivation’, ‘augmented feedback’, ‘golden triangle’). Planning the essay for Section C with a brief mind‑map ensures logical flow and synoptic links that examiners reward.
高分技巧：准确使用专业术语（如“副交感神经再激活”“增强反馈”“金三角”）。在 C 部分写小论文前用简短的思维导图规划，可确保逻辑流畅和跨主题联系，这是阅卷人看重的。
