剑桥 IGCSE 体育课程要求学生将理论与实践紧密结合。11 年级学生必须掌握解剖学、生理学、心理学和社会文化影响。本文提炼了最高频的考点和典型错误，帮助你精准复习，抓住重点。

1. Skeletal System: Bone Names, Functions and Classification | 骨骼系统：骨骼名称、功能与分类

Students often confuse the functions of the skeleton. Remember, the five key functions are support, protection, movement, mineral storage and blood cell production. A common mistake is stating ‘shape’ instead of ‘support’ – support refers to the framework holding the body upright.

学生常常混淆骨骼的功能。请记住，五大功能是：支撑、保护、运动、矿物质储存和血细胞生成。常见错误是把“塑造体型”说成“支撑”——支撑是指骨架使身体保持直立。

Be precise with bone names: the femur is the thigh bone, not just ‘leg bone’. The tibia is the larger lower leg bone, fibula the thinner one. In the vertebral column, identify cervical (7), thoracic (12), lumbar (5), sacrum and coccyx. Examiners frequently ask to label these on a diagram.

骨骼名称要准确：股骨是大腿骨，不能简单写“腿骨”。胫骨是小腿较粗的骨头，腓骨较细。脊柱的组成要分清：颈椎（7）、胸椎（12）、腰椎（5）、骶骨和尾骨。考官经常要求在图上标注这些结构。

Bone (英文)	中文	Function (功能)
Cranium	颅骨	Protects brain 保护大脑
Ribs & Sternum	肋骨和胸骨	Protect heart/lungs 保护心肺
Vertebrae	椎骨	Protects spinal cord 保护脊髓

Common error: Mixing up axial and appendicular skeleton. The axial skeleton includes skull, ribs, sternum and vertebral column. Appendicular includes limbs and girdles.

常见错误：混淆中轴骨与附肢骨骼。中轴骨包括颅骨、肋骨、胸骨和脊柱；附肢骨骼包括四肢和带骨。

2. Muscular System: Voluntary, Involuntary, Cardiac and Muscle Contractions | 肌肉系统：随意肌、不随意肌、心肌与肌肉收缩

Know the three muscle types: voluntary (skeletal), involuntary (smooth) and cardiac. Voluntary muscles are under conscious control and attach to bones via tendons. Involuntary muscles work automatically, found in walls of blood vessels and intestines. Cardiac muscle is special – it’s involuntary but striated like skeletal muscle.

掌握三种肌肉类型：随意肌（骨骼肌）、不随意肌（平滑肌）和心肌。随意肌受意识支配，通过肌腱附着于骨骼。不随意肌自动工作，见于血管壁和肠道。心肌很特殊——它是不随意的，却像骨骼肌一样有横纹。

Major muscles to label: deltoid, biceps, triceps, pectorals, abdominals, latissimus dorsi, gluteals, quadriceps, hamstrings, gastrocnemius. A frequent error is swapping biceps and triceps location or confusing hamstrings with quadriceps. Note that the biceps is on the anterior upper arm, triceps on the posterior.

需要标注的主要肌肉：三角肌、肱二头肌、肱三头肌、胸肌、腹肌、背阔肌、臀肌、股四头肌、腘绳肌、腓肠肌。常见错误是把肱二头肌和肱三头肌位置互换，或者混淆腘绳肌和股四头肌。注意，肱二头肌在上臂前侧，肱三头肌在后侧。

Muscle contractions: isotonic (concentric – muscle shortens, eccentric – muscle lengthens) and isometric (no change in length). Many learners forget that eccentric contractions also produce tension, just while lengthening. In a bicep curl, lowering the weight is eccentric.

肌肉收缩形式：等张收缩（向心——肌肉缩短，离心——肌肉拉长）和等长收缩（长度不变）。很多学生忘记离心收缩同样产生张力，只是在拉长时。在二头弯举中，下落重量就是离心收缩。

3. Joints: Types, Structure and Range of Movement | 关节：类型、结构与运动范围

Synovial joints are the main focus. Be able to describe the structure: synovial membrane, synovial fluid, articular cartilage, joint capsule, ligaments. The fluid lubricates the joint, cartilage reduces friction, ligaments connect bone to bone. Tendons are often wrongly described as part of the joint – they connect muscle to bone.

滑膜关节是重点。要能描述结构：滑膜、滑液、关节软骨、关节囊、韧带。滑液润滑关节，软骨减少摩擦，韧带连接骨与骨。肌腱常被错误地视为关节的一部分——肌腱连接的是肌肉和骨骼。

Know the six types of synovial joints and their movements: ball and socket (hip/shoulder – flexion, extension, abduction, adduction, rotation, circumduction), hinge (elbow/knee – flexion/extension), pivot (neck – rotation), condyloid (wrist – flexion/extension, abduction/adduction), saddle (thumb – opposition), gliding (carpals – small sliding movements). A classic mistake is calling the knee a ball and socket joint.

了解六种滑膜关节及其运动：球窝关节（髋/肩——屈曲、伸展、外展、内收、旋转、环转），铰链关节（肘/膝——屈曲/伸展），枢轴关节（颈部——旋转），髁状关节（腕——屈曲/伸展、外展/内收），鞍状关节（拇指——对掌），滑动关节（腕骨——小幅度滑动）。典型错误是把膝关节说成球窝关节。

易错点： The term ‘rotation’ in a ball and socket joint refers to turning around the long axis of the bone, not spinning like a wheel. Circumduction is a combination of flexion, extension, abduction and adduction.

易错点：球窝关节的“旋转”是指绕骨长轴转动，不同于车轮般的旋转。环转是屈曲、伸展、外展和内收的组合运动。

4. Respiratory System: Mechanics of Breathing and Lung Volumes | 呼吸系统：呼吸机制与肺容量

Explain inspiration and expiration. During inspiration, the diaphragm contracts and flattens, intercostal muscles contract, rib cage moves up and out, thoracic volume increases, pressure decreases, air rushes in. During expiration at rest, these muscles relax, elastic recoil occurs. During exercise, expiration becomes active using abdominal muscles to force air out quicker.

解释吸气与呼气。吸气时，膈肌收缩变平，肋间肌收缩，肋骨上提外移，胸腔体积增大，压力降低，空气涌入。安静呼气时，这些肌肉放松，发生弹性回缩。运动时，呼气转为主动，利用腹肌快速排出空气。

Common error: confusing the roles of diaphragm and intercostals. Some students say ‘lungs expand then air comes in’, but it’s the chest expansion that creates negative pressure, drawing air into the lungs. Also remember that the lungs themselves contain no muscle tissue.

常见错误：混淆膈肌和肋间肌的作用。有些学生说“肺先扩张，然后空气进入”，实际上胸腔扩张产生负压，从而把空气吸入肺中。还要记住，肺本身不含肌肉组织。

Key volumes: tidal volume (TV), vital capacity (VC), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), residual volume. In a spirometer trace, identify them. A typical mistake is reading the trace incorrectly for minute ventilation. Minute ventilation (VE) = tidal volume × breathing frequency (f). e.g., TV = 0.5 L, f = 12 breaths/min → VE = 6 L/min.

关键容量：潮气量（TV）、肺活量（VC）、吸气储备量（IRV）、呼气储备量（ERV）、残气量。在肺活量计描记图中识别它们。常见错误是错误计算每分通气量。每分通气量 (VE) = 潮气量 × 呼吸频率 (f)。例如，TV = 0.5 L，f = 12 次/分 → VE = 6 L/min。

5. Cardiovascular System: Heart, Cardiac Cycle & Blood Vessels | 心血管系统：心脏、心动周期与血管

The heart is a double pump: right side pumps deoxygenated blood to the lungs (pulmonary circulation), left side pumps oxygenated blood to the body (systemic circulation). Know the chambers, valves (tricuspid, bicuspid/mitral, pulmonary semilunar, aortic semilunar) and the pathway of blood. Many candidates incorrectly draw blood from left ventricle going to the lungs.

心脏是双泵：右侧将缺氧血泵至肺部（肺循环），左侧将富氧血泵至全身（体循环）。掌握心腔、瓣膜（三尖瓣、二尖瓣、肺动脉半月瓣、主动脉半月瓣）和血流路径。许多考生错误地画出左心室血液流向肺部的路线。

Cardiac cycle: diastole (relaxation, atria and ventricles fill), atrial systole (atria contract, forcing blood into ventricles), ventricular systole (ventricles contract, AV valves close, semilunar valves open). Heart rate (HR), stroke volume (SV) and cardiac output (Q) are linked: Q = HR × SV. An error is thinking that SV decreases during exercise; it actually increases due to greater venous return (Starling’s law).

心动周期：舒张期（放松，心房心室充盈），心房收缩期（心房收缩，血液挤入心室），心室收缩期（心室收缩，房室瓣关闭，半月瓣打开）。心率（HR）、每搏输出量（SV）和心输出量（Q）的关系：Q = HR × SV。常见错误是认为运动中每搏输出量下降；实际上它因静脉回流量增加而增加（斯塔林定律）。

Blood vessels: arteries carry blood away from heart (thick muscular, elastic walls, high pressure), veins carry blood toward heart (thinner walls, valves, low pressure), capillaries are one-cell thick for gaseous exchange. Misconception: not all arteries carry oxygenated blood (pulmonary artery carries deoxygenated). Similarly, pulmonary vein carries oxygenated blood.

血管：动脉将血液送离心脏（管壁厚，肌肉弹力强，压力高），静脉将血液送回心脏（管壁较薄，有瓣膜，压力低），毛细血管仅一层细胞厚，便于气体交换。误区：并非所有动脉都运输富氧血（肺动脉运输缺氧血）。同样，肺静脉运输富氧血。

6. Energy Systems: ATP-PC, Lactic Acid and Aerobic | 能量系统：ATP-PC 系统、乳酸系统与有氧系统

Muscles need ATP for contraction. Three systems resynthesize ATP. ATP-PC (phosphocreatine) system is anaerobic, lasts 8–10 seconds, used for explosive activities like sprinting, jumping, throwing. Lactic acid system (anaerobic glycolysis) provides energy from glucose without oxygen, produces lactic acid, lasts about 60–90 seconds, e.g. 400m run. Aerobic system uses oxygen to break down carbohydrates and fats, sustains activity for long durations.

肌肉收缩需要 ATP。有三个系统可以再合成 ATP。ATP-PC（磷酸肌酸）系统是无氧的，持续 8–10 秒，用于爆发性活动，如短跑、跳跃、投掷。乳酸系统（无氧糖酵解）在不使用氧气的情况下从葡萄糖供能，产生乳酸，持续时间约 60–90 秒，如 400 米跑。有氧系统利用氧气分解碳水化合物和脂肪，可长时间供能。

Common mistake: confusing the duration of ATP-PC and lactic acid systems. ATP-PC is immediate but very short; lactic acid kicks in when ATP-PC is depleted, peaking around 30–45 seconds. Another error is not linking the systems to sports – students may say a marathon runner uses the aerobic system, which is correct, but forget to mention that at the final sprint, the lactic acid system is engaged.

常见错误：混淆 ATP-PC 和乳酸系统的持续时间。ATP-PC 是即刻供能但非常短；ATP-PC 耗竭后乳酸系统介入，约在 30-45 秒达到峰值。还有一个错误是不把系统与运动项目关联——学生可能说马拉松运动员使用有氧系统，这是对的，但忘了提最后冲刺时乳酸系统也会参与。

Recovery and oxygen debt (EPOC): excess post-exercise oxygen consumption. The fast component restores ATP/PC stores and reloads myoglobin with oxygen; the slow component removes lactic acid. In exams, candidates often state EPOC is simply to ‘repay oxygen debt’, without explaining the specific recovery processes.

恢复与氧债（EPOC）：运动后过量氧耗。快速阶段用于恢复 ATP/PC 储备和肌红蛋白氧合；慢速阶段清除乳酸。考试中，考生常说 EPOC 就是“偿还氧债”，却不解释具体的恢复过程。

7. Principles of Training: SPORR and FITT | 训练原则：SPORR 与 FITT

SPORR stands for Specificity, Progression, Overload, Reversibility and Rest & Recovery. Overload must be applied using the FITT principle: Frequency, Intensity, Time, Type. Mistake: confusing overload with progression. Overload is the immediate stress beyond normal levels; progression is the gradual increase of that stress over time.

SPORR 代表：特异性、渐进性、超负荷、可逆性和休息恢复。超负荷需通过 FITT 原则实施：频率、强度、时间、类型。常见错误：混淆超负荷与渐进性。超负荷是即时的超常压力；渐进性是随时间逐步增加压力。

Specificity is often misunderstood. It means training must match the energy system, muscle groups and movement patterns of the sport. A shot-putter needs explosive strength training, not long slow distance. Reversibility (detraining) occurs when you stop – gains are lost faster than they were acquired.

特异性常被误解。它意味着训练必须匹配运动项目的能量系统、肌群和动作模式。铅球运动员需要爆发力训练，而不是长距离慢跑。可逆性（停训）在停止训练时发生——体能消退比获得更快。

In exam, a question might present a training programme and ask which principle is missing. A typical error is misidentifying the need for rest days – the programme may lack adequate recovery, leading to overtraining.

考试中，可能会给出一个训练计划，问缺少了哪项原则。典型错误是没认出需要休息日——计划可能缺乏足够的恢复，导致过度训练。

8. Skill Acquisition and Information Processing | 技能习得与信息处理

Skills classification: open/closed, gross/fine, discrete/serial/continuous, self-paced/externally paced. An open skill is affected by the environment (e.g., a football pass), closed is predictable (e.g., a gymnastics routine). A common error is calling a penalty kick in football a closed skill; it is actually open because of the goalkeeper’s unpredictable movements and crowd noise.

技能分类：开放/封闭、粗大/精细、分立/序列/连续、自定节奏/外部节奏。开放技能受环境影响（如足球传球），封闭技能环境稳定可预测（如体操规定动作）。常见错误是把足球点球称为封闭技能；实际上因守门员的不可预测动作和观众噪音，它属于开放技能。

Information processing model: input, decision-making, output, feedback. Whiting’s model adds perceptual mechanisms, translatory mechanisms and effector mechanisms. Many students forget that feedback can be intrinsic (kinaesthesis) or extrinsic (coach, video). For learning, novice athletes benefit more from extrinsic feedback.

信息处理模型：输入、决策、输出、反馈。怀廷模型还包含感知机制、转译机制和效应机制。许多学生忘记反馈可以是内在的（肌肉动觉）或外在的（教练、视频）。对初学者而言，外在反馈更有益。

易错点： Confusing motor programme with schema. A motor programme is a set of pre-planned movements for a specific skill. Schema theory states we adapt generalised motor programmes based on recall schema and recognition schema.

易错点：混淆动作程序与图式。动作程序是一套为特定技能预先计划的动作。图式理论认为我们通过回忆图式和再认图式来调整一般动作程序。

9. Levers in the Human Body | 人体中的杠杆系统

All three lever classes exist in the body. First class: fulcrum between effort and load (e.g., neck extending – head as load, neck muscles effort, fulcrum at atlanto-occipital joint). Second class: load between fulcrum and effort (e.g., standing on tiptoes – ball of foot fulcrum, body weight load, calf muscles effort). Third class: effort between fulcrum and load (most common, e.g., biceps curl – elbow fulcrum, biceps effort, hand weight load).

人体中存在全部三种杠杆类型。第一类：支点在力点与重点之间（如颈部后伸——头为重点，颈肌为力点，寰枕关节为支点）。第二类：重点在支点与力点之间（如提踵站立——前脚掌支点，体重为重点，小腿肌为力点）。第三类：力点在支点与重点之间（最常见，如二头弯举——肘为支点，二头肌为力点，手中重量为重点）。

Error: claiming that the majority of body levers are second class. Actually, third class levers dominate, as they favour speed and range of movement over force production. The mechanical disadvantage of third class levers is compensated by the muscle’s ability to generate force.

错误：认为人体大多数是第二类杠杆。实际上第三类杠杆占主导，因为它们有利于速度和运动幅度，而非力量输出。第三类杠杆的机械劣势由肌肉产生力的能力来弥补。

Remember to draw and label simple lever diagrams. Mechanical advantage = effort arm / load arm. Most body levers have mechanical advantage less than 1, meaning they need a larger effort to move a small load, but they produce a large range and speed at the end of the limb – ideal for throwing or kicking.

记得画出并标注简单的杠杆示意图。机械利益 = 力臂 / 重臂。人体多数杠杆的机械利益小于 1，意味着需要较大的力才能移动较小的负荷，但在肢体末端能产生较大的活动范围和速度——非常适合投掷或踢腿动作。

10. Health, Fitness and Components of Fitness | 健康、体适能与体适能成分

Health is a state of complete physical, mental and social well-being. Fitness is the ability to meet the demands of the environment. Health-related components: cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition. Skill-related components: agility, balance, coordination, power, reaction time, speed.

健康是一种完整的身体、心理和社会福祉状态。体适能是满足环境需求的能力。与健康相关的体适能成分：心肺耐力、肌肉力量、肌肉耐力、柔韧性、身体成分。与技能相关的成分：敏捷性、平衡、协调、爆发力、反应时、速度。

Many candidates confuse muscular strength (maximal force in one contraction) with muscular endurance (ability to sustain repeated contractions). Also, power is often mislabelled as strength. Power = force × velocity; it’s about how quickly force is applied. A vertical jump test measures power, not pure strength.

许多考生混淆肌肉力量（单次收缩的最大力量）和肌肉耐力（持续重复收缩的能力）。此外，爆发力常被标记为力量。爆发力 = 力 × 速度；它与施力速度有关。纵跳测试测量的是爆发力，而非纯力量。

When asked to design a fitness test battery, avoid selecting inappropriate tests. E.g., the 12-minute Cooper run tests cardiovascular endurance, not muscular endurance. The handgrip dynamometer test is for strength, not endurance.

被要求设计体适能测试组合时，避免选择不当测试。例如，12 分钟库珀跑测试的是心肺耐力，而非肌肉耐力。握力计测试的是力量，而非耐力。

11. Sports Injuries and Prevention | 运动损伤与预防

Acute injuries occur suddenly (fractures, dislocations, sprains – ligament damage, strains – muscle/tendon damage). Chronic injuries develop over time (tendonitis, stress fractures, shin splints). A major error is mixing up sprain and strain. Sprain = ligament, strain = muscle/tendon.

急性损伤发生突然（骨折、脱臼、扭伤——韧带损伤、拉伤——肌肉/肌腱损伤）。慢性损伤逐渐形成（肌腱炎、应力性骨折、胫骨骨膜炎）。主要错误是混淆扭伤和拉伤。扭伤=韧带，拉伤=肌肉/肌腱。

Injury prevention: correct warm-up and cool-down, appropriate equipment, safe playing environment, fair play and rule enforcement. The RICE method (Rest, Ice, Compression, Elevation) is for immediate soft tissue injury management. Often, students forget to explain why ice is used: vasoconstriction reduces swelling and pain.

损伤预防：正确热身与整理活动、合适的装备、安全的运动环境、公平竞赛与规则执行。RICE 方法（休息、冰敷、加压、抬高）用于软组织损伤的即时处理。学生经常忘记解释为什么用冰敷：血管收缩可以减少肿胀和疼痛。

Concussion recognition is now heavily emphasised. Signs: headache, dizziness, confusion, memory loss. Any suspected concussion must result in immediate removal from play and medical assessment. ‘If in doubt, sit them out’ is a common exam phrase.

脑震荡的识别现在备受重视。迹象：头痛、眩晕、意识混乱、失忆。任何疑似脑震荡必须立即退场并接受医学评估。“有疑问，就不上场”是考试常用语。

12. Social and Ethical Issues in Sport | 体育中的社会与道德议题

Topics include sportsmanship, gamesmanship, deviance, performance-enhancing drugs (PEDs), blood doping, violence, and commercialisation. Sportsmanship is fair play and respect; gamesmanship is bending the rules without breaking them (e.g., time-wasting). Deviance involves breaking rules (e.g., deliberate foul).

议题包括：体育精神、竞技取巧、越轨行为、兴奋剂、血液回输、暴力、商业化。体育精神是公平竞争和尊重；竞技取巧是钻规则空子但不违规（如拖延时间）。越轨行为涉及违规（如故意犯规）。

Drug categories: stimulants, narcotic analgesics, anabolic agents, peptide hormones, diuretics, beta blockers. Be able to identify the effect and a sporting example. e.g., beta blockers reduce heart rate and anxiety, used in archery/shooting. Error: claiming beta blockers are stimulants.

药物类别：兴奋剂、麻醉性镇痛剂、同化制剂、肽类激素、利尿剂、β-阻断剂。能够识别效果并举例运动项目。例如，β-阻断剂降低心率和焦虑，用于射箭/射击。错误：声称 β-阻断剂是兴奋剂。

Commercialisation: gold triangle of sport, media and sponsorship. Positive effects: increased funding, role models, wider participation. Negative: minority sports overlooked, scheduling for TV, pressure from sponsors, loss of traditional values. Exam questions often ask for balanced arguments.

商业化：体育、媒体和赞助的黄金三角。积极影响：增加资金、树立榜样、扩大参与。消极影响：小众运动被忽视、为电视转播安排赛程、赞助商压力、传统价值观丧失。考题常要求平衡论证。
