📚 CIE A-Level Physical Education: Core Concepts & Study Plan | CIE A-Level 体育：核心知识点与学习规划
Cambridge International A Level Physical Education (syllabus code 9396) is an applied, science-informed subject. It combines human movement science with socio-cultural and psychological perspectives, and it asks candidates to connect theory to real sporting situations. This guide outlines the essential knowledge blocks and gives a practical revision timetable for the full A Level course.
剑桥国际A Level体育课程（大纲编号9396）是一门以循证科学为基础的应用型学科。它将人体运动科学与社会文化、心理视角相结合，并要求考生将理论联系到真实运动情境中。下文梳理了核心知识模块，并为完整A Level课程提供了一份可执行的学习规划。
1. Syllabus Map and Assessment | 1. 课程体系与测评框架
The full CIE A Level is made up of AS and A2 content. Candidates are assessed through written examinations plus a practical coursework component. Written papers typically test applied anatomy and physiology, biomechanics, skill acquisition, sports psychology, exercise physiology and contemporary issues in physical education and sport.
完整CIE A Level由AS与A2内容组成，考生通常需要通过笔试和实践性课程作业完成测评。笔试一般覆盖应用解剖与生理、生物力学、技能习得、运动心理学、运动生理学以及当代体育议题。
The practical component asks learners to perform, observe, analyse and improve movement. This means you need not only factual knowledge but also the ability to evaluate performance and design an evidence-based training or coaching plan.
实践环节要求学生完成运动表现、观察、分析与改进。这意味着你不仅需要掌握事实性知识，还需要具备评价运动表现并设计循证训练或指导计划的能力。
| Assessment focus | 测评重点 | Common requirement | 常见要求 |
| Written theory | 笔试理论 | Short answers, extended response and multiple-choice items | 简答题、论述题与选择题 |
| Coursework | 课程作业 | Performance in one physical activity plus analysis | 一项运动表现及分析改进报告 |
Always consult the current CIE syllabus for exact paper weighting and route options, as centres may register candidates for staged AS or full A Level entry.
请务必查阅最新CIE大纲，以确认各张试卷的具体权重和考试路线，因为考试中心可能选择分阶段AS或直接参加完整A Level。
2. Anatomy: Bones, Joints and Muscles | 2. 解剖学：骨骼、关节与肌肉
The skeletal system provides support, protection, mineral storage and blood cell formation. Long bones act as levers, while flat bones protect vital organs such as the heart and brain. The axial skeleton is the core of the body, and the appendicular skeleton enables movement.
骨骼系统提供支撑、保护、矿物质储存和造血功能。长骨充当杠杆，扁骨保护心脏、大脑等重要器官。中轴骨骼是身体的核心，附肢骨骼则负责运动。
Synovial joints are the most mobile joints in the body. The shoulder and hip are ball-and-socket joints allowing flexion, extension, abduction, adduction, rotation and circumduction. The elbow and knee are hinge joints, which mainly permit flexion and extension.
滑膜关节是人体活动度最大的关节。肩关节和髋关节属于球窝关节，可完成屈、伸、外展、内收、旋转和环转运动；肘关节和膝关节属于枢纽关节，主要完成屈伸运动。
Stability at joints is provided by ligaments, tendons, capsule, cartilage and muscle tone. In a sporting tackle or sudden change of direction, the dynamic stabilisation of muscles around the knee and ankle is essential for injury prevention.
关节的稳定性由韧带、肌腱、关节囊、软骨和肌张力共同维持。在体育中的冲撞或突然变向时，膝、踝周围肌肉的动态稳定能力对预防损伤至关重要。
For movement, muscles work in pairs. At the elbow, the biceps brachii is the agonist during flexion and the triceps brachii becomes the agonist during extension. Contraction types include concentric, eccentric and isometric contractions.
运动由成对肌群完成。屈肘时肱二头肌是主动肌，伸肘时肱三头肌变为主动肌。肌肉收缩类型包括向心收缩、离心收缩和等长收缩。
3. Physiology: Cardiovascular and Respiratory Systems | 3. 生理学：心血管与呼吸系统
The cardiovascular system transports oxygen, nutrients, hormones and waste products. The heart has four chambers and works as a double pump. Cardiac output is a central measure of endurance performance.
心血管系统负责运输氧气、营养物质、激素和代谢废物。心脏有四个腔室，起到双泵作用。心输出量是评价耐力表现的核心指标。
Cardiac output (Q) = Stroke volume (SV) × Heart rate (HR)
心输出量（Q）= 每搏输出量（SV）× 心率（HR）
During sub-maximal exercise, stroke volume increases gradually and reaches a plateau. Heart rate therefore becomes the main factor that raises cardiac output. Training lowers resting heart rate and improves the efficiency of the heart.
亚极量运动时，每搏输出量逐渐上升并趋于平台，因此心率成为提高心输出量的主要因素。训练可降低静息心率并提高心脏效率。
In the respiratory system, air moves down the trachea into the bronchial tree and reaches the alveoli. Gas exchange happens by simple diffusion: oxygen enters the blood and carbon dioxide leaves it. Haemoglobin combines with oxygen to form oxyhaemoglobin.
呼吸系统中，空气经气管进入支气管树，最终到达肺泡。气体交换通过简单扩散完成：氧气进入血液，二氧化碳排出体外。血红蛋白与氧结合形成氧合血红蛋白。
Maximal oxygen uptake, or VO₂ max, reflects the body's ability to absorb, transport and use oxygen. It is limited by cardiac output, blood haemoglobin content and mitochondrial capacity.
最大摄氧量（VO₂ max）反映人体吸入、运输和利用氧气的能力，其大小受心输出量、血红蛋白含量和线粒体能力限制。
4. Bioenergetics: Energy Systems | 4. 生物能量学：供能系统
All muscular contraction requires adenosine triphosphate (ATP). ATP stores energy in high-energy phosphate bonds. When ATP breaks down, it releases energy for movement.
一切肌肉收缩都需要三磷酸腺苷（ATP）。ATP将能量储存在高能磷酸键中，当ATP分解时释放能量以支持运动。
ATP → ADP + Pi + Energy
ATP → ADP + 磷酸 + 能量
There are three energy systems: the ATP-PC system, the anaerobic glycolytic (lactic acid) system and the aerobic system. They operate on a continuum rather than being switched on one at a time.
人体共有三种供能系统：ATP-PC系统、无氧糖酵解（乳酸）系统和有氧系统。它们不是逐一启用的开关，而是在一个连续轴上协同运作。
| System | 系统 | Key feature | 核心特点 |
| ATP-PC | Very fast, limited to ~10 seconds, no oxygen and no lactate | 速度最快，约10秒内，不需氧气也不产生乳酸 |
| Lactic acid | Fast, lasts about 30 seconds to 2 minutes, produces lactate | 较快，约30秒至2分钟，产生乳酸 |
| Aerobic | Slow, high ATP yield, uses oxygen, produces CO₂ and water | 较慢，生成ATP量大，利用氧气，产物为二氧化碳和水 |
After high-intensity exercise, oxygen consumption remains elevated. This is often described as excessive post-exercise oxygen consumption (EPOC), sometimes called oxygen debt. It helps restore phosphocreatine, remove lactate and return body temperature to normal.
高强度运动后，摄氧量仍会维持在高位，这常被称为运动后过量氧耗（EPOC），有时也叫氧债。它有助于恢复磷酸肌酸、清除乳酸并使体温恢复正常。
5. Biomechanics in Movement | 5. 运动中的生物力学
Biomechanics uses the laws of physics to analyse sport technique. Newton's three laws of motion are fundamental to sprinting, throwing and jumping. For example, a sprint start requires the athlete to push back against the blocks; the ground reacts in the opposite direction.
生物力学运用物理学定律分析运动技术。牛顿三大力学定律是短跑、投掷和跳跃的基础。例如，短跑起跑时运动员蹬离起跑器，地面便产生相反方向的反作用力。
Levers allow a force to act over distance. In the human body, most levers are third-class levers, where the effort lies between the fulcrum and the load; this favours speed and range of movement over force.
杠杆可使力作用于一定距离。人体内多数杠杆属于第三类杠杆，即力点在支点和阻力点之间；这类杠杆优先提供速度和运动幅度，而不是力量。
Projectile motion is crucial for throwing and jumping. The optimum angle of release depends on release height and air resistance. When release and landing heights are equal, a projectile launched at 45° obtains maximum horizontal range in a vacuum.
抛射运动对投掷和跳跃至关重要。最佳出手角度取决于出手高度与空气阻力。当出手点与落点高度相同且忽略空气阻力时，以45°角抛出的物体获得最大水平距离。
Range = (v² × sin 2θ) / g
射程 =（初速度² × sin 2θ）/ 重力加速度
Stability increases when the centre of mass is low, the base of support is large, and the line of gravity falls close to the centre of the base. This principle is used in wrestling stances and rugby scrums.
降低重心、增大支撑面、使重力线落在支撑面中心附近，都能提高稳定性。摔跤防守姿势和橄榄球争球就运用了这一原理。
