1. Energy System Contribution and Interplay | 能量系统贡献与相互作用
The ATP-PC system relies on stored phosphocreatine and dominates maximal efforts lasting 0–10 seconds; it resynthesises ATP without oxygen and with no fatiguing by-products.
ATP-PC 系统依赖储存的磷酸肌酸，主导 0–10 秒的最大强度运动；它在无氧条件下再合成 ATP，不产生导致疲劳的副产物。
The anaerobic glycolytic system breaks down glucose to resynthesise ATP for high-intensity activities lasting roughly 10–60 seconds, producing lactate and hydrogen ions that contribute to muscular acidosis.
无氧糖酵解系统通过分解葡萄糖为 10–60 秒的高强度运动再合成 ATP，过程中生成乳酸和氢离子，引发肌肉酸化。
The aerobic system provides energy for submaximal exercise lasting longer than 2 minutes, using carbohydrates and fats in the presence of oxygen; its yield is high but the rate is slow.
有氧系统为持续 2 分钟以上的亚极量运动供能，在有氧条件下利用碳水化合物和脂肪，能量产量高但供能速率慢。
Common mistake: Students frequently label a single system as the sole provider for a given duration, whereas all three systems intermix from the onset of exercise. The dominant system shifts, but the other pathways remain active. Also, many confuse the fuel for anaerobic glycolysis—muscle glycogen, not blood glucose alone.
常见错误：学生常常认为某段时间只有单一系统供能，事实上三种系统从运动开始就协同工作，只是主导系统发生转换，其他通路仍然活跃。此外，许多人误以为无氧糖酵解的燃料只是血糖，其实主要是肌糖原。
2. EPOC Components and Implications | 运动后过量氧耗的组成与影响
Excess post-exercise oxygen consumption (EPOC) is split into the fast alactacid component—restoring phosphocreatine and myoglobin oxygen stores in 2–3 minutes—and the slow lactacid component, which handles lactate oxidation, elevated heart rate, hormone circulation, and core temperature over 30–60 minutes.
运动后过量氧耗（EPOC）分为快速非乳酸期——在 2–3 分钟内恢复磷酸肌酸和肌红蛋白氧储备——以及慢速乳酸期，需要在 30–60 分钟内处理乳酸氧化、心率升高、激素循环和核心体温恢复等过程。
A typical error is misattributing lactate removal to the fast component. In reality, the fast component is independent of lactate, and the slow component reflects the cost of returning the body to homeostasis.
常见错误是把乳酸清除归到快速期。事实上快速期与乳酸无关，慢速期才是身体恢复稳态的耗氧代价。
Another frequent mistake is using the outdated term 'oxygen debt' without distinguishing EPOC's sub-components, which is essential for high-mark answers.
另一个高频错误是沿用过时的“氧债”概念，未区分 EPOC 的组成部分，这在追求高分的答案中是不可取的。
3. Periodisation and Tapering for Peak Performance | 周期化训练与减量以达最佳表现
Periodisation organises a training year into macrocycles (the whole season), mesocycles (4–12 week blocks targeting specific goals), and microcycles (often one week). The preparatory, competitive, and transition phases allow progressive overload and recovery.
周期化训练把整个训练年分为大周期（整个赛季）、中周期（4–12周，聚焦特定目标）和小周期（通常一周）。准备期、竞赛期和过渡期使渐进超负荷与恢复成为可能。
Tapering is a key pre-competition strategy: volume is reduced by 40–60% while intensity is maintained or slightly increased, optimising glycogen stores, neuromuscular function, and psychological readiness.
减量训练是关键赛前策略：减少 40–60% 的训练量，同时维持或略微提高强度，从而优化糖原储备、神经肌肉功能和心理状态。
Common mistake: Learners often propose reducing both volume and intensity during a taper, which leads to detraining. Others fail to justify the duration (typically 7–21 days) and neglect to link tapering to physiological markers.
常见错误：学生常提出在减量期同时降低训练量和强度，导致能力下降；又或者未论证减量时长（通常为 7–21 天），也未能将减量与生理指标相联系。
4. Multidimensional Anxiety and Catastrophe | 多维焦虑与灾难模型
Martens' multidimensional anxiety theory distinguishes cognitive anxiety (worries, negative thoughts) from somatic anxiety (physiological symptoms such as increased heart rate). Both can independently affect performance.
Martens 的多维焦虑理论区分了认知焦虑（担忧、消极思维）与躯体焦虑（心率升高等生理症状），两者可独立影响运动表现。
Hardy's catastrophe model adds that cognitive anxiety acts as the trigger: when arousal rises beyond an optimal point and cognitive anxiety is high, performance can drop suddenly—a 'catastrophe'—rather than decline gradually.
Hardy 的灾难模型补充指出，认知焦虑是扳机：当唤醒水平超出最佳点且认知焦虑较高时，表现会突然暴跌——出现“灾难”而非逐渐下降。
Common mistake: Students often treat the catastrophe model as simply an extension of the inverted-U hypothesis, missing the critical role of cognitive anxiety as a binary switch. They also confuse the recovery pathway: after a catastrophe, performance does not return directly to the previous level; arousal must drop significantly before rebuilding.
常见错误：学生常把灾难模型仅当作倒 U 假说的延伸，忽略了认知焦虑作为开关的关键作用。他们也混淆恢复路径：灾难发生后，表现不能直接回到原来水平，必须先大幅降低唤醒再重新建立。
5. Theories of Aggression in Sport | 运动攻击性理论
Instinct theory (Lorenz) claims aggression is innate, building up until released through catharsis. The frustration-aggression hypothesis (Dollard) states that frustration always precedes aggression, and aggressive acts reduce the drive.
本能理论（Lorenz）认为攻击性是天生的，会积累直到通过宣泄释放。挫折-攻击假说（Dollard）则主张挫折总是引发攻击，攻击行为可减弱驱力。
Bandura's social learning theory contends that aggression is acquired by observing and imitating role models, reinforced by vicarious experience and direct rewards.
Bandura 的社会学习理论认为攻击性是通过观察和模仿榜样习得的，经由替代性经验和直接奖励得到强化。
Common mistake: Candidates frequently mislabel assertive behaviour as aggression. Assertion is legitimate force within the rules, with no intent to harm; aggression involves intent. In exams, they also apply frustration-aggression theory too rigidly, forgetting that frustration can lead to withdrawal or alternative responses.
常见错误：考生常把果敢行为误标为攻击。果敢是规则范围内不含伤害意图的正当力量；攻击则有伤害意图。考试中，他们也过于刻板地应用挫折-攻击理论，忘记挫折也可能导致退缩或其他反应。
6. Cohesion: Task and Social Dimensions | 凝聚力：任务与社交维度
Carron's conceptual model identifies four antecedents of cohesion: environmental factors (contracts, size), personal factors (motivation, satisfaction), leadership factors (style, decision-making), and team factors (shared experiences, stability).
Carron 的概念模型确定了凝聚力的四个前因：环境因素（合约、规模）、个人因素（动机、满意度）、领导因素（风格、决策）和团队因素（共享经历、稳定性）。
Task cohesion reflects commitment to group goals, whereas social cohesion reflects interpersonal attraction. Task cohesion is typically a stronger predictor of performance in sports teams.
任务凝聚力反映对团队目标的投入，社交凝聚力反映人际吸引。在运动团队中，任务凝聚力通常更能预测运动表现。
Common mistake: Students assume that higher social cohesion always enhances performance, but excessive socialising can distract from task focus. They also fail to differentiate between cohesion and mere team stability; high turnover squads can still develop task cohesion through clear roles.
常见错误：学生总以为社交凝聚力越高表现越好，但过度的社交可能分散任务专注。他们也未能区分凝聚力与简单的团队稳定性；高流动率的队伍仍可通过明确角色建立任务凝聚力。
7. Commercialisation, Sponsorship, and the Gold Triangle | 商业化、赞助与黄金三角
The 'golden triangle' describes the interdependent relationship between sport, media, and sponsorship. Media exposure attracts sponsors, sponsorship funds elite sport, and sport provides content for media.
“黄金三角”描述了体育、媒体和赞助之间相互依存的关系：媒体曝光吸引赞助商，赞助资金支撑精英体育，体育则为媒体提供内容。
Commercialisation impacts sport at all levels: rule changes (e.g., tie-breaks in tennis), scheduling shifts for TV audiences, and the growth of merchandise sales. However, it can also widen inequalities between high-profile and minority sports.
商业化在各个方面影响体育：规则改变（如网球抢七）、为电视观众调整赛程、商品销售增长等，但它也可能加剧主流运动与小众运动之间的不平等。
Common mistake: Weaker responses merely list pros and cons without connecting them to specific stakeholders. For example, 'increased revenue for NGBs' needs linking to grassroots participation programmes. Many also overlook the negative ethical influence of sponsor demands on sport integrity.
常见错误：较弱的答案只罗列优缺点，不与具体利益相关者联系。例如，“NGB 收入增加”需要与基层参与计划挂钩。许多人还忽略了赞助商需求对体育诚信的负面伦理影响。
8. Doping Classification and Ethical Concerns | 兴奋剂分类与伦理问题
WADA classifies prohibited substances into categories including anabolic agents (muscle gain, e.g., testosterone), stimulants (alertness, e.g., amphetamines), diuretics (masking, rapid weight loss), beta blockers (steady hands, e.g., in archery), narcotic analgesics (pain masking), and peptide hormones (e.g., EPO for oxygen transport).
WADA 将禁用物质分类为促蛋白合成剂（增肌，如睾酮）、刺激剂（提神，如安非他命）、利尿剂（掩盖、快速减重）、β-阻断剂（手稳，如射箭项目）、麻醉镇痛剂（掩盖疼痛）和肽类激素（如促红细胞生成素 EPO，提升氧气运输）。
Ethical debates revolve around fairness, health risks, and role-modelling. Anti-doping arguments stress that doping undermines the spirit of sport, while some argue for a regulated 'medicalised' approach to reduce harm.
伦理争论围绕公平性、健康风险和榜样作用展开。反兴奋剂论点强调兴奋剂破坏体育精神，也有声音主张进行受监管的“医学化”以降低危害。
Common mistake: Students frequently confuse which substances benefit which sports—beta blockers help archery, not powerlifting. They also struggle to articulate both the intrinsic (cheating) and extrinsic (health) moral arguments, often presenting a one-sided view.
常见错误：学生经常混淆哪些物质有助于哪些运动——β-阻断剂有利于射箭，而非举重。他们也不能清晰地同时表达内在（作弊）和外在（健康）的道德论点，常常只呈现片面观点。
9. Newton's Laws and Projectile Motion | 牛顿定律与抛射体运动
Newton's first law (inertia) is evident in a sprinter' ma) explains acceleration proportional to applied force. The third law (action-reaction) is visible when a swimmer pushes water backward to move forward.
牛顿第一定律（惯性）体现在短跑运动员起跑时需要力量克服惯性。第二定律（F=ma）说明加速度与外力成正比。第三定律（作用-反作用）在游泳者向后推水从而前进时清晰可见。
For projectile motion, the optimal projection angle in a vacuum is 45°. In sport, factors such as release height, air resistance, and the required horizontal displacement mean the optimum is often less than 45° (e.g., shot put around 28–36°).
抛射运动中，真空中最佳出射角为 45°。但在运动中，由于出射高度、空气阻力和所需水平位移的影响，最佳角度通常小于 45°（如铅球约为 28–36°）。
Range = (V² × sin 2θ) / g
射程 = (V² × sin 2θ) / g
Common mistake: Learners routinely quote 45° as the universal optimal angle without adjusting for release height. In long jump, take-off height and angle interact to determine flight distance, and students often neglect the contribution of vertical impulse at take-off.
常见错误：学生通常不加调整地将 45° 当作普适最佳角度，忽略了出射高度。跳远中，起跳高度与角度的相互作用决定飞行距离，而学生常忽略起跳时垂直冲击的贡献。
10. Learning and Performance Habits: Feedback Types | 学习与表现习惯：反馈类型
Fitts and Posner's three stages of learning are cognitive (learner understands the task, frequent errors), associative (refinement and consistency), and autonomous (automatic execution, low cognitive load). Selective attention and feedback demands change at each stage.
Fitts 和 Posner 的学习三阶段分别为认知阶段（学习者理解任务、错误频出）、联结阶段（细化动作且趋于稳定）和自主阶段（自动化执行、认知负荷低）。每个阶段对注意力和反馈的需求都不同。
Feedback is categorised as intrinsic (internal, kinesthetic) and extrinsic (augmented by coach/video). Extrinsic feedback splits into knowledge of results (KR—outcome) and knowledge of performance (KP—movement quality).
反馈分为内在反馈（内部的、动觉）和外在反馈（由教练或视频增强）。外在反馈又分为结果知晓（KR—结果）和表现知晓（KP—动作质量）。
Common mistake: Students often misapply feedback for autonomous performers, prescribing continuous extrinsic KR when intrinsic feedback and occasional KP suffice. Another error is failing to link feedback type to the learner's processing capacity; too much KP during the cognitive stage can cause overload.
常见错误：学生常为自主阶段运动员错误地开出持续的外在结果反馈，其实内在反馈和偶尔的表现知晓（KP）就够了。另一个错误是未将反馈类型与学习者处理能力挂钩；认知阶段给出过多 KP 会导致信息超载。
