1. Cardiovascular System During Exercise | 运动时心血管系统
creases linearly with intensity until it reaches maximum, stroke volume (SV) rises up to around 40–60% liver more oxygen to working muscles. Students often lose marks by failing to explain the plateau in stroke volume or confusing cardiac output with minute ventilation.
心血管系统在运动中会发生急性适应。心率随强度线性上升直至最大值，每搏输出量在约 40–60% 最大摄氧量强度时达到平台期，心输出量（Q = HR × SV）随之增加，为工作肌群输送更多氧气。学生常丢分的地方是未能解释每搏输出量为何出现平台期，或者将心输出量与每分通气量混淆。
- The increase in venous return via the muscle pump and respiratory pump raises end-diastolic volume, which increases SV via the Frank-Starling mechanism. / 通过肌肉泵和呼吸泵增加的静脉回流量提高了舒张末期容积，通过弗兰克–斯塔林机制提高每搏输出量。
- At high intensities, reduced ventricular filling time prevents further SV rise. / 在高强度运动时，心室充盈时间缩短，阻止了每搏输出量进一步上升。
- A common mistake is writing that SV continues to rise throughout exercise; examiners expect you to mention the plateau and link it to filling time. / 常见错误是写每搏输出量在整个运动过程中持续上升；考官希望你能提到平台期，并将其与充盈时间联系起来。
2. Respiratory System and Oxygen Transport | 呼吸系统与氧气运输
ng frequency) rises dramatically during exercise, with tidal volume plateauing at about 50–60% ial pressure gradients. Students often mislabel the oxygen dissociation curve and forget to explain the Bohr shift during exercise.
每分通气量（VE = 潮气量 × 呼吸频率）在运动中大幅上升，潮气量在达到肺活量的 50–60% 左右时进入平台期。肺泡和肌肉处的气体交换依赖于分压梯度。学生经常把氧解离曲线的坐标轴标错，并且忘记解释运动中的波尔效应。
- Increased temperature, increased pCO₂, and decreased pH in working muscles cause the oxyhaemoglobin dissociation curve to shift to the right (Bohr shift), facilitating oxygen unloading. / 工作肌肉中温度升高、二氧化碳分压上升、pH 值下降会使氧合血红蛋白解离曲线右移（波尔效应），促进氧气释放。
- A typical error is stating that the curve shifts left during exercise because of increased oxygen demand, which is the opposite of reality. / 常见错误是声称曲线在运动中因需氧增加而左移，完全颠倒了事实。
3. Muscle Fibre Types and Recruitment | 肌纤维类型与动员
ruitment follows Henneman’s size principle: Type I → Type IIa → Type IIx as force demand increases. Students often lose marks by misidentifying fibre characteristics or failing to link fibre type to specific sporting examples.
骨骼肌含有 I 型（慢缩氧化）、IIa 型（快缩氧化酵解）和 IIx 型（快缩酵解）纤维。动员顺序遵循亨内曼的大小原则：随力量需求增加，依次动员 I 型 → IIa 型 → IIx 型。学生常因误判纤维特性或未能将纤维类型与具体运动项目联系起来而失分。
- Type I fibres: high mitochondria, high capillary density, high aerobic capacity, low fatigability. Typical in marathon runners. / I 型纤维：线粒体多，毛细血管密度高，有氧能力高，不易疲劳。典型见于马拉松运动员。
- Type IIx fibres: high glycogen stores, high anaerobic enzyme activity, fast contraction time, very fatigable. Suited to 100 m sprint. / IIx 型纤维：糖原储备高，无氧酶活性高，收缩时间快，极易疲劳。适合 100 米短跑。
- Beware of stating that Type IIa are purely anaerobic – they are intermediate and can adapt to aerobic or anaerobic training. / 注意不要说 IIa 型是纯粹的无氧纤维——它们是中间型，可向有氧或无氧方向适应。
4. Energy Systems: ATP-PC, Glycolytic, and Aerobic | 能量系统：ATP-CP、糖酵解与有氧
The three energy systems work together, but the contribution of each depends on intensity and duration. The ATP-PC system provides energy for up to 10 seconds, the glycolytic (lactic acid) system dominates from about 10–90 seconds, and the aerobic system takes over for longer-duration, submaximal exercise. Common exam mistakes include confusing the fuel sources, forgetting ATP yield, and misplacing the threshold points.
三大能量系统协同工作，但各系统的贡献取决于运动强度和持续时间。ATP-CP 系统提供最多 10 秒钟的能量，糖酵解系统在约 10–90 秒占主导，有氧系统在长时间次最大强度运动中接手。考试常见错误包括混淆燃料来源、忘写 ATP 产量以及搞错系统切换的时间节点。
- ATP-PC: fuel is phosphocreatine, yield is 1 ATP per PC molecule, no by-products. / ATP-CP：燃料是磷酸肌酸，每分子 PC 产生 1 个 ATP，无副产物。
- Anaerobic glycolytic: fuel is glucose/glycogen, yield is 2 ATP per glucose, by-product is lactate and H⁺. / 无氧糖酵解：燃料是葡萄糖/糖原，每分子葡萄糖产生 2 个 ATP，副产物为乳酸和氢离子。
- Aerobic: fuels include glycogen and fatty acids, yield is ~38 ATP per glucose, by-products CO₂ and H₂O. / 有氧系统：燃料包括糖原和脂肪酸，每分子葡萄糖约产生 38 个 ATP，副产物为二氧化碳和水。
- Do not write that lactic acid is produced – lactate and hydrogen ions are produced separately. / 不要写产生乳酸——实际产生的是乳酸根和氢离子，二者分开。
5. Energy Continuum and Interplay | 能量连续统一体与系统相互作用
The energy continuum describes how the relative contribution of the three energy systems shifts during a single bout of exercise. At the start of a 1500 m race, all three systems are active: ATP-PC provides immediate power, the glycolytic system ramps up quickly, and the aerobic system gradually becomes the primary provider after about 60–90 seconds. Students often describe the systems as switching on and off, which is incorrect – they blend.
能量连续统一体描述的是一次运动中三大能量系统的相对贡献如何动态变化。在 1500 米比赛开始时，三个系统同时工作：ATP-CP 提供即时功率，糖酵解系统快速上升，有氧系统在约 60–90 秒后逐渐成为主要供能者。学生常把系统描述成开关式切换，这是错误的——它们是此消彼长的融合过程。
- In the first 10 seconds, ATP-PC dominates (>80%), glycolytic contributes some, aerobic minimal. / 前 10 秒，ATP-CP 占主导（>80%），糖酵解部分贡献，有氧极低。
- Between 30–60 seconds, glycolytic system peaks, aerobic contribution increases, ATP-PC almost exhausted. / 30–60 秒间，糖酵解系统达峰值，有氧贡献上升，ATP-CP 几乎耗尽。
- After 2 minutes, aerobic system dominant (>90%). / 两分钟后，有氧系统占主导（>90%）。
- Examiners penalise answers that state one system 'takes over' or 'stops working'. / 考官会扣分如果答案说某个系统“接管”或“停止工作”。
6. Skill Classification and Transfer of Learning | 技能分类与学习迁移
Skills can be classified along several continua: open–closed, gross–fine, discrete–serial–continuous, self-paced–externally paced, and simple–complex. Transfer of learning can be positive, negative, zero, proactive, retroactive, or bilateral. A common mistake is to confuse proactive transfer (a previously learned skill affects a new one) with retroactive transfer (a new skill affects an old one).
运动技能可沿多个连续体分类：开放–闭锁、粗大–精细、分立–序列–连续、自定节奏–外部节奏、简单–复杂。学习迁移可分为正迁移、负迁移、零迁移、前摄迁移、倒摄迁移和双侧迁移。常见错误是把前摄迁移（旧技能影响学新技能）和倒摄迁移（新技能影响旧技能）混淆。
- Positive transfer: learning a tennis serve helps learning a volleyball serve. / 正迁移：学习网球发球有助于学习排球发球。
- Proactive transfer: a previously learned overarm throw affects learning a javelin throw. / 前摄迁移：先前学会的过肩投掷影响学习标枪投掷。
- Retroactive transfer: learning a golf putting stroke might alter a previously learned hockey push, particularly if negative. / 倒摄迁移：学习高尔夫推杆可能会改变先前学会的曲棍球推球，尤其是负迁移时。
- Ensure you can give sporting examples for each type – vague statements cost marks. / 确保能为每一种迁移类型举出运动实例——笼统陈述会丢分。
7. Information Processing and Memory | 信息加工与记忆
Information processing models (e.g., Welford's, Whiting's) explain how we make decisions. The display provides environmental information, the sense organs receive it, perception involves interpreting stimuli, and the translatory mechanism compares input to long-term memory before the effector mechanism produces a response. Students often miss marks by omitting the role of selective attention in filtering irrelevant information.
信息加工模型（如 Welford 模型、Whiting 模型）解释我们如何作出决策。显示系统提供环境信息，感觉器官接收信息，感知涉及对刺激的解读，转换机制将输入与长时记忆比对后，由效应器机制产生反应。学生常因遗漏选择性注意在过滤无关信息中的作用而失分。
- Selective attention filters only relevant cues (e.g., the flight of the ball in cricket batting) to the perceptual mechanism, preventing information overload. / 选择性注意只把相关线索（如板球击球时球的飞行轨迹）过滤到感知机制，防止信息过载。
- Short-term memory (working memory) has limited capacity (7±2 items) and duration (~30 seconds). Rehearsal and chunking can aid transfer to long-term memory. / 短时记忆（工作记忆）容量有限（7±2 个项目），持续时间约 30 秒。复述和组块策略有助于转入长时记忆。
- A typical error is to name the memory stores without explaining their function in a sporting context. / 典型错误是仅仅列出记忆储存库名称，却不解释它们在运动情境中的功能。
8. Feedback and Stages of Learning | 反馈与学习阶段
Feedback types include intrinsic, extrinsic (knowledge of results and knowledge of performance), positive, negative, concurrent, and terminal. The optimal feedback type depends on the learner's stage: cognitive, associative, or autonomous. Exam questions often ask you to justify why a certain type of feedback suits a particular stage, and students fall short by not linking feedback to the performer's needs.
反馈类型包括内反馈、外反馈（结果反馈和过程反馈）、正面反馈、负面反馈、同时反馈和终端反馈。最佳反馈类型取决于学习者所处的阶段：认知阶段、联结阶段或自主阶段。考题常要求你解释为什么某种反馈适合某个阶段，学生因未能将反馈与练习者需求挂钩而答得不够深入。
- Cognitive stage: beginners need extrinsic, positive, and terminal feedback to build basic understanding. Avoid concurrent feedback as it can overload the learner. / 认知阶段：初学者需要外反馈、正面反馈和终端反馈来建立基本理解。避免同时反馈，否则可能给学习者造成过载。
- Associative stage: a mix of extrinsic and intrinsic feedback, with more knowledge of performance for refinement. / 联结阶段：外反馈与内反馈混合，更多使用过程反馈来精细化动作。
- Autonomous stage: mainly intrinsic, concurrent feedback with occasional negative feedback to correct subtle errors. / 自主阶段：主要靠内反馈和同时反馈，偶尔使用负面反馈纠正细微错误。
- Be specific: write 'knowledge of performance helps a swimmer adjust arm pull mechanics' rather than just 'extrinsic feedback is useful'. / 回答要具体：写出“过程反馈帮助游泳者调整划臂动作机制”，而不是泛泛地说“外反馈有用”。
9. Arousal, Anxiety, and Performance | 唤醒、焦虑与运动表现
heory suggests performance = habit × drive (dominant response). Catastrophe theory adds that high cognitive anxiety combined with high physiological arousal can cause a sudden drop in performance. Students frequently misapply drive theory to beginners or fail to distinguish between somatic and cognitive anxiety.
连接唤醒与表现的理论每年都会考查。倒U理论预测中等唤醒水平下表现最佳；驱力理论认为表现 = 习惯 × 驱力（优势反应）。灾难理论补充指出，高认知焦虑与高生理唤醒结合可能导致表现突然崩溃。学生常把驱力理论错误地套用在初学者身上，或未能区分躯体焦虑和认知焦虑。
- Inverted-U: optimal arousal is moderate for most skills, lower for fine/closed skills, higher for gross/open skills. / 倒U理论：大部分技能的适宜唤醒处于中等水平，精细/闭锁性技能适宜更低唤醒，粗大/开放性技能适宜更高唤醒。
- Drive theory: an expert performer's dominant response is the correct one, so high arousal improves performance; a beginner's dominant response is likely incorrect, so high arousal harms performance. / 驱力理论：高手的优势反应是正确的动作，因此高唤醒提升表现；初学者的优势反应很可能是错误的，高唤醒反而损害表现。
- Catastrophe theory: under high cognitive anxiety, once arousal passes a threshold, performance crashes and cannot recover even if arousal drops slightly. / 灾难理论：在高认知焦虑下，一旦唤醒超过阈值，表现会骤降，即使唤醒稍微回落也无法立即恢复。
- Mixing up somatic (physiological) and cognitive (worry) anxiety in a single answer loses marks. / 在同一个答案中把躯体（生理）焦虑与认知（担忧）焦虑混为一谈会丢分。
10. Achievement Motivation Theory | 成就动机理论
Atkinson’s achievement motivation model explains the need to achieve (Nach) and need to avoid failure (Naf). High Nach performers seek challenging but achievable tasks (approach behaviour), while high Naf performers avoid 50-50 situations and choose either very easy or very hard tasks to protect self-esteem. Common errors include confusing Nach with introverted personality or failing to link to sporting choices.
阿特金森的成就动机模型解释了追求成功（Nach）和避免失败（Naf）两种倾向。高 Nach 的运动员倾向选择有挑战但可实现的任务（趋近行为），而高 Naf 的人会避开一半一半的机会，选择极简单或极难的任务以维护自尊。常见错误是把 Nach 与内向性格混淆，或者没有联系到运动选择上。
- A high Nach footballer will volunteer for penalty shootouts; a high Naf player will claim injury to avoid the high-risk moment. / 高追求成功的足球运动员会主动要求踢点球大战；高避免失败的球员会声称受伤来避开高风险时刻。
- Situational factors like probability of success and incentive value interact with personality. / 情境因素如成功概率和激励价值，与个性相互作用。
- Do not simply describe Nach and Naf – explain how they affect behaviour in competitive situations. / 不要只描述追求成功和避免失败的定义——要解释它们如何在竞争情境中影响行为。
11. Sport and Society: 19th-Century Public Schools | 体育与社会：19 世纪公立学校
The development of rational recreation in 19th-century England is a guaranteed exam topic. Public schools like Eton and Rugby moved from 'boy culture' of disorderly play through the 'cult of athleticism' to become the breeding ground of codified team games. Students lose marks by missing the clear three-stage evolution and confusing stage characteristics.
19 世纪英格兰的理性休闲体育发展是必考题。类似伊顿公学和拉格比公学等公立学校，从无序的“少年文化”，经过“体育崇拜”阶段，最终成为有规则团队运动的孵化地。学生丢分往往是因为遗漏了清晰的三阶段演变过程，并把各阶段的特征搞混。
- Stage 1 (Pre-1800): Barbarian boy culture – fagging, bullying, recreational violence; masters turned a blind eye. / 第一阶段（1800 年前）：野蛮少年文化——受低年级生奴役、霸凌、娱乐性暴力；教师视而不见。
- Stage 2 (Clarendon reforms, mid-19th century): Thomas Arnold promoted muscular Christianity and the use of games to instil discipline, loyalty, and moral values. Houses, prefects, and inter-house competitions emerged. / 第二阶段（克拉伦登改革，19 世纪中期）：托马斯·阿诺德推广“强身基督教”，用游戏灌输纪律、忠诚和道德价值观。学社、学长制和学社间比赛出现。
- Stage 3 (Late 19th century): Cult of athleticism – games became central to school life, rules were codified, leagues and governing bodies formed, and these sports spread via the old boys. / 第三阶段（19 世纪末）：体育崇拜——游戏成为学校生活核心，规则被规范，联盟和管理机构形成，这些运动通过校友扩散到全国。
- Link public school development to the characteristics of modern sports: codification, regular competition, secularism, and social stratification. / 把公立学校的发展与现代竞技运动的特点联系起来：规则成文化、定期比赛、世俗化和社会阶层分化。
12. Technology, Drugs, and the Spirit of Sport | 科技、兴奋剂与体育精神
Technological aids can enhance performance, but they raise ethical questions about fairness and the spirit of sport. Drug testing, gene doping, hypoxic chambers, and prosthetic devices challenge the boundaries. Students often give one-sided arguments or fail to weight both positive and negative impacts with specific examples.
科技辅助手段能提升运动表现，但也引发了关于公平和体育精神的伦理问题。药检、基因兴奋剂、低氧仓和假肢装置不断挑战着界限。学生常给出单方面论述，或者未能用具体例子权衡正反两方面影响。
- Positive: carbon-fibre prostheses allow Paralympians to compete; skin suits reduce drag in swimming. / 正面：碳纤维义肢让残奥运动员得以参赛；紧身泳衣减少游泳时的阻力。
- Negative: technological doping (high-tech swimsuits banned in 2010) gives unfair advantage; hypoxic chambers raise cost barriers; drug masking agents increase health risks. / 负面：技术兴奋剂（高科技泳衣在 2010 年被禁）带来不公平优势；低氧仓提高了成本门槛；药物掩蔽剂增加健康风险。
- Address the Perry model of moral reasoning and ethical decision-making when discussing drug use in sport. / 在讨论体育中的药品使用问题时，要提到佩里道德推理模型和伦理决策。
- Ensure you can define blood doping, beta blockers, anabolic steroids, and EPO, and explain their physiological effects and risks. / 确保你能明确定义血液兴奋剂、β-受体阻滞剂、合成类固醇和促红细胞生成素，并解释其生理效应和风险。
