剑桥国际 AS Level 体育（9396）课程将科学理论与实践表现相结合，让学生深入了解人体在运动和锻炼中的运作方式。这份全面解析将带你逐一了解 Year 12 课程的各个方面，从评估结构到核心知识领域，帮助你有效规划复习与课程作业。
1. Course Overview and Aims | 课程概览与目标
The CIE AS Physical Education course is designed to develop both theoretical knowledge and practical competence. Learners explore the scientific principles underpinning physical performance and health, while also refining their own sporting abilities. The syllabus aims to: promote understanding of anatomy, exercise physiology and biomechanics; encourage analysis and evaluation of movement and training; foster an appreciation of lifelong physical activity; and prepare students for further study in sport sciences, physiotherapy or coaching.
CIE AS 体育课程旨在同时发展理论知识和实践能力。学习者探究支撑运动表现和健康的科学原理，同时提升自身的运动技能。课程目标包括：促进对解剖学、运动生理学和生物力学的理解；鼓励分析评估动作与训练；培养终身体育活动的意识；并为学生在运动科学、物理治疗或教练领域的深造做好准备。
The AS Level serves as the first half of the full A Level, providing a strong foundation in three core theoretical areas alongside practical coursework. Students are expected to relate classroom concepts to real sporting examples and their own performance.
AS 阶段是完整 A Level 的前半部分，为三大核心理论领域及实践课程作业奠定坚实基础。学生需要将课堂概念与实际运动案例及自身表现相联系。
2. Assessment Structure | 评估结构
AS Physical Education is assessed through two components: a written theory paper and a practical coursework portfolio. The table below summarises the key details.
AS 体育通过两个部分进行评估：书面理论考试和实践课程作业档案。下表概括了关键信息。
| Component | Marks | Weighting | Duration |
|---|---|---|---|
| Paper 1: Theory | 100 | 70% | 2 h 30 min |
| Paper 2: Coursework | 60 | 30% | Ongoing |
Paper 1 consists of three sections: Anatomy and Physiology, Exercise Physiology, and Biomechanics. Questions include structured items, data response and extended writing, testing both recall and application. Paper 2 requires students to submit evidence of performance in two chosen physical activities, plus an oral response analysing one of them. Coursework is internally assessed and externally moderated.
试卷一包含三个部分：解剖与生理学、运动生理学和生物力学。题目包括结构化简答、数据分析和论述题，考查记忆与应用能力。试卷二要求学生提交两项所选体育活动的表现证据，外加一份针对其中一项的口头分析。课程作业由校内评估、外部审核。
Success in both components demands a consistent approach: deep theoretical understanding and regular practical engagement go hand in hand. The 70% theory weighting means that mastering the written paper is essential for a high grade.
要在两个部分都取得好成绩需要持续努力：深入的理论理解与规律的实践参与相辅相成。理论考试占 70% 的权重，因此掌握书面考试是高分的必要条件。
3. Anatomy and Physiology – Skeletal and Muscular Systems | 骨骼与肌肉系统
This section explores the structures that create movement. The skeleton provides support, protection, mineral storage and blood cell production. It is divided into the axial skeleton (skull, vertebral column, rib cage) and the appendicular skeleton (limbs and girdles). Key bones and their functions appear regularly in exam questions.
这一部分探讨产生运动的结构。骨骼提供支撑、保护、矿物质储存和血细胞生成。它分为中轴骨（颅骨、脊柱、胸廓）和附肢骨（四肢及带骨）。关键骨骼及其功能经常出现在考试题目中。
Joints are classified by structure and function. Synovial joints – such as hinge (elbow), ball and socket (hip) and pivot (atlanto-axial) – allow free movement and are central to sporting actions. Each synovial joint features articular cartilage, a joint capsule, synovial fluid, ligaments and often menisci or bursae.
关节按结构和功能分类。滑膜关节——如屈戌关节（肘）、球窝关节（髋）和车轴关节（寰枢关节）——允许大幅度活动，是运动动作的核心。每个滑膜关节都有关节软骨、关节囊、滑液、韧带，并常伴有半月板或滑囊。
Muscles produce force through contraction. Skeletal muscle is made up of bundles of fibres containing myofibrils. The sliding filament theory explains how myosin heads pull actin filaments inward, shortening the sarcomere. This process requires calcium ions and ATP. Motor units, consisting of a motor neuron and the fibres it innervates, control force gradation.
肌肉通过收缩产生力量。骨骼肌由含有肌原纤维的肌束构成。肌丝滑行理论解释了肌球蛋白头如何拉动肌动蛋白丝向内滑动，使肌小节缩短。这一过程需要钙离子和 ATP。运动单位由一个运动神经元及其支配的肌纤维组成，控制力量分级。
Fibre types vary in contraction speed and fatigue resistance. Type I (slow oxidative) fibres suit endurance, Type IIa (fast oxidative glycolytic) support middle-distance events, and Type IIx (fast glycolytic) deliver explosive power. Training can shift fibre characteristics within limits.
肌纤维类型在收缩速度和抗疲劳性上有所差异。I 型（慢缩氧化型）适合耐力运动，IIa 型（快缩氧化酵解型）适合中距离项目，IIx 型（快缩酵解型）提供爆发力。训练可在一定程度内改变纤维特性。
4. Anatomy and Physiology – Cardiovascular and Respiratory Systems | 心血管与呼吸系统
The cardiovascular system transports oxygen, nutrients and waste products. The heart has four chambers; the left ventricle has the thickest wall because it pumps blood around the whole body. Cardiac output is the product of heart rate and stroke volume.
心血管系统运输氧气、营养物质和废物。心脏有四个腔室；左心室壁最厚，因为它将血液泵送至全身。心输出量是心率与每搏输出量的乘积。
Q = HR x SV
During exercise, heart rate increases via the sympathetic nervous system, while stroke volume rises due to increased venous return and myocardial stretch (Starling’s law). Blood is redistributed to working muscles through vasodilation and vasoconstriction.
运动期间，心率通过交感神经系统升高，而每搏输出量因静脉回流增加和心肌拉伸（斯塔林定律）而上升。血液通过血管舒张和收缩重新分配到工作肌肉。
The respiratory system conducts air from the atmosphere to the alveoli, where gas exchange occurs. Minute ventilation is the volume of air breathed per minute. At rest it is about 6 L/min, but during maximal exercise it can exceed 150 L/min in trained athletes. Oxygen diffuses from alveoli into pulmonary capillaries, while carbon dioxide moves in the opposite direction.
呼吸系统将空气从大气传导至肺泡，在此进行气体交换。每分通气量是每分钟呼吸的空气量。安静时约为 6 升/分钟，但训练有素的运动员极量运动时可超过 150 升/分钟。氧气从肺泡扩散到肺毛细血管，二氧化碳则反向移动。
V̇O₂ max, maximal oxygen uptake, represents the upper limit of aerobic capacity. It depends on central factors (cardiac output) and peripheral factors (capillary density, mitochondrial volume). Understanding these systems is vital for analysing performance and designing training programmes.
V̇O₂ max，即最大摄氧量，代表有氧能力的上限。它取决于中枢因素（心输出量）和外周因素（毛细血管密度、线粒体数量）。理解这些系统对于分析运动表现和设计训练计划至关重要。
5. Exercise Physiology – Energy Systems and Recovery | 运动生理学 – 能量系统与恢复
All movement relies on adenosine triphosphate (ATP). Because muscles store only small amounts of ATP, three energy systems resynthesise it at different rates. The ATP-PC system provides immediate energy for up to 10 seconds, using phosphocreatine without oxygen. This powers explosive efforts like a 100 m sprint or a vertical jump.
所有动作都依赖三磷酸腺苷（ATP）。由于肌肉仅储存少量 ATP，三个能量系统以不同速率重新合成它。ATP-PC 系统在无氧条件下利用磷酸肌酸即时供能，持续约 10 秒，为 100 米冲刺或纵跳等爆发力动作提供能量。
PC + ADP → ATP + Creatine
The lactic acid (anaerobic glycolytic) system breaks down glucose without oxygen, producing ATP and lactic acid. It dominates high-intensity efforts lasting 30–120 seconds, such as a 400 m run. Accumulation of hydrogen ions lowers pH, contributing to fatigue.
乳酸（无氧酵解）系统在无氧条件下分解葡萄糖，产生 ATP 和乳酸。它主导持续 30 至 120 秒的高强度运动，如 400 米跑。氢离子的积累降低 pH 值，导致疲劳。
The aerobic system yields the most ATP by fully oxidising glucose or fatty acids in mitochondria. It supports prolonged, low-to-moderate intensity activity. The Krebs cycle and electron transport chain operate here. Recovery from high-intensity work involves excess post-exercise oxygen consumption (EPOC), which restores phosphocreatine, removes lactate and replenishes oxygen stores.
有氧系统通过在线粒体中完全氧化葡萄糖或脂肪酸产生最多的 ATP。它支持长时间、中低强度的活动。克雷布斯循环和电子传递链在此运行。高强度运动后的恢复涉及运动后过量氧耗（EPOC），用于恢复磷酸肌酸、清除乳酸并补充氧气储备。
6. Exercise Physiology – Training Principles and Nutrition | 训练原则与营养
Effective training programmes apply the principles of individuality, specificity, progression, overload and reversibility. The FITT acronym (Frequency, Intensity, Time, Type) helps manipulate overload. Reversibility means that fitness gains are lost when training stops. Periodisation organises training into macrocycles, mesocycles and microcycles to peak at the right time.
有效的训练计划遵循个体差异、专项性、渐进性、超负荷和可逆性原则。FITT 缩写（频率、强度、时间、类型）有助于调控超负荷。可逆性意味着停训后体能增益会消退。周期化将训练划分为大周期、中周期和小周期，以便在恰当时机达到巅峰状态。
Training methods must align with the targeted energy system. Continuous training improves aerobic endurance, while high-intensity interval training (HIIT) develops both aerobic and anaerobic capacity. Resistance training builds strength, power and muscular endurance by applying progressive overload. Plyometrics uses stretch-shortening cycles to boost explosive power.
训练方法必须与目标能量系统匹配。持续训练可提升有氧耐力，而高强度间歇训练（HIIT）能同时发展有氧和无氧能力。抗阻训练通过渐进超负荷增强力量、爆发力和肌耐力。超等长训练利用牵张-缩短循环提高爆发力。
Nutrition provides the fuel and building blocks for performance. Carbohydrates are the main energy source for high-intensity work, while fats fuel low-intensity exercise. Protein supports muscle repair and adaptation. Hydration is critical; even 2% dehydration can impair performance. Vitamins and minerals assist energy metabolism and muscle function.
营养为运动表现提供燃料和构建原料。碳水化合物是高强度运动的主要能源，脂肪则为低强度运动供能。蛋白质支持肌肉修复与适应。水合作用至关重要；即使仅脱水 2% 也会降低运动表现。维生素和矿物质辅助能量代谢与肌肉功能。
7. Biomechanics – Forces and Motion | 生物力学 – 力与运动
Biomechanics applies mechanical principles to human movement. Newton’s three laws of motion form the basis. The Law of Inertia states that a body will remain at rest or in uniform motion unless acted on by an external force. The Law of Acceleration links force, mass and acceleration.
生物力学将机械原理应用于人体运动。牛顿三定律是其基础。惯性定律指出，除非受外力作用，物体将保持静止或匀速直线运动状态。加速度定律将力、质量和加速度联系起来。
F = m x a
The Law of Reaction explains that every action has an equal and opposite reaction, crucial when pushing against the ground or water. Linear motion describes movement along a straight or curved path. Key variables include displacement, velocity and acceleration.
反作用定律说明每个作用力都有一个大小相等、方向相反的反作用力，这在推离地面或水中时至关重要。线性运动描述沿直线或曲线路径的移动。关键变量包括位移、速度和加速度。
v = u + at
Angular motion involves rotation around an axis. Torque (moment of force) causes angular acceleration. The moment of inertia depends on mass distribution relative to the axis of rotation; a tucked body spins faster than an extended one. Balance and stability rely on centre of mass, base of support and line of gravity.
角运动涉及绕轴旋转。力矩（力对转动的效应）产生角加速度。转动惯量取决于质量相对于旋转轴的分布；团身姿势比伸展姿势转动更快。平衡与稳定性依赖于质心、支撑面和重力线。
8. Biomechanics – Projectile Motion and Lever Systems | 抛体运动与杠杆系统
Projectile motion analyses the flight of objects or the human body after release. The path is determined by release velocity, angle and height. The optimal angle for maximum range on a flat surface is 45° when release and landing heights are equal. Air resistance and spin (Magnus effect) can significantly alter trajectories in sports like football or golf.
抛体运动分析物体或人体离手后的飞行轨迹。轨迹由出手速度、角度和高度决定。在平地情况下，出手高度与落地高度相等时，最大远度的最佳角度为 45°。在足球或高尔夫等运动中，空气阻力和旋转（马格努斯效应）会显著改变飞行路径。
Lever systems explain how muscles produce effective force. A lever has a fulcrum (joint), effort (muscle force) and load (resistance). First-class levers (e.g., neck extension) place the fulcrum between effort and load. Second-class levers (e.g., ankle plantar flexion) have the load between fulcrum and effort, giving a mechanical advantage greater than 1. Third-class levers (e.g., elbow flexion) have the effort between fulcrum and load, sacrificing force for speed and range of motion – the most common type in the body.
杠杆系统解释肌肉如何产生有效的力。杠杆由支点（关节）、动力（肌力）和阻力（负荷）组成。第一类杠杆（如颈部后伸）支点在动力与阻力之间。第二类杠杆（如踝关节跖屈）阻力位于支点和动力之间，机械效益大于 1。第三类杠杆（如肘关节屈曲）动力在支点与阻力之间，虽然牺牲了力量，但换来了速度和活动范围——这是人体中最常见的类型。
Mechanical advantage (MA) = effort arm / resistance arm. Understanding lever mechanics helps coaches optimise technique and reduce injury risk.
机械效益（MA）= 动力臂 / 阻力臂。理解杠杆力学有助于教练优化技术动作并降低损伤风险。
9. Practical Coursework (Component 2) | 实践课程作业
The coursework component bridges theory and real-world performance. Students must select two physical activities from the approved CIE list, which includes sports like athletics, swimming, association football, badminton and dance. They are assessed on their ability to execute skills, apply tactics and demonstrate fitness in competitive or formal situations.
课程作业部分将理论与实际表现联系起来。学生必须从 CIE 批准的活动列表中选取两项运动，包括田径、游泳、足球、羽毛球和舞蹈等。评估他们在比赛或正式情境中执行技能、运用战术和展示体能的能力。
Evidence is gathered through video recordings, logbooks or official observation reports. The oral response requires candidates to analyse their own performance in one activity, applying anatomical, physiological or biomechanical knowledge to explain strengths and areas for improvement. This interview-style task demands confident communication and subject-specific vocabulary.
证据通过视频录像、日志或官方观察报告收集。口头回答要求考生运用解剖学、生理学或生物力学知识，分析自己在一项活动中的表现，解释优势与改进领域。这项面试式任务需要自信的沟通和学科专业词汇。
Top marks go to students who plan their evidence collection early, seek regular feedback and link clearly to syllabus theory. Practising under pressure and reviewing sample oral responses are effective strategies.
高分学生通常提前规划证据收集、定期寻求反馈，并将实践与课程理论清晰地联系起来。在压力下练习和复习样本口头回答是有效的策略。
10. Study and Revision Strategies | 学习与复习策略
Mastering AS Physical Education requires regular recall and application. Start by breaking the syllabus into manageable topics and using the specification as a checklist. Create flashcards for key definitions, such as cardiac output, EPOC or mechanical advantage, and test yourself frequently.
掌握 AS 体育需要定期回忆和应用。首先要将大纲分解为可管理的小专题，并用考纲作为核对清单。制作关键定义的抽认卡，如心输出量、EPOC 或机械效益，并经常自测。
