This revision guide highlights the high-frequency topics and analyses the most common mistakes, helping Year 11 learners boost their exam performance.
CIE IGCSE 体育（0413）涵盖从解剖生理学到心理学和训练方法的广泛内容。许多学生在考试中反复出现的特定概念上容易出错。本复习指南聚焦高频考点，分析典型易错题，帮助11年级学生提升考试成绩。
1. Respiratory System: Tidal Volume vs. Vital Capacity | 呼吸系统：潮气量与肺活量
A high-frequency exam question asks students to define tidal volume and distinguish it from vital capacity. Tidal volume is the amount of air inhaled and exhaled during a normal breath at rest, typically around 500 mL. Vital capacity is the maximum amount of air that can be forcibly exhaled after a maximal inhalation.
考试中经常要求学生定义潮气量并将其与肺活量区分开。潮气量是安静状态下每次正常呼吸吸入和呼出的气体量，通常约为500毫升。肺活量则是一次最大吸气后再尽最大能力呼出的气体总量。
The most common mistake is confusing the two. Many candidates write that tidal volume is the maximum air moved in one breath, which is actually vital capacity. Another error is describing tidal volume as the air left in the lungs after exhalation—that is residual volume.
最常见的错误是混淆这两个概念。不少考生把潮气量写成一次呼吸的最大气体量，这其实是肺活量。另一个错误是将潮气量描述为呼气后留在肺内的气体，那属于残气量。
To avoid these pitfalls, always link tidal volume to resting conditions and vital capacity to maximum effort. Exam command words often require comparisons, so be ready to state that tidal volume increases during exercise but vital capacity remains relatively unchanged.
为避免这些陷阱，始终将潮气量与安静状态联系起来，而肺活量则与最大用力相关。考题中常出现比较类指令词，所以要准备好说明运动时潮气量增加而肺活量基本保持不变。
| Common Confusion | Correct Answer |
|---|---|
| Tidal volume = maximum air breathed out | That is vital capacity |
| Vital capacity = air left in lungs | That is residual volume |
2. Cardiovascular System: Cardiac Output and Stroke Volume | 心血管系统：心输出量与每搏输出量
Cardiac output (Q) is the volume of blood pumped by the heart per minute. It is calculated as heart rate (HR) multiplied by stroke volume (SV). Many students memorise the equation but fail to explain the changes during exercise correctly.
心输出量（Q）是心脏每分钟泵出的血液量，用心率（HR）乘以每搏输出量（SV）计算。许多学生记住了公式，但无法正确解释运动时的变化。
A typical mistake is stating that stroke volume continues to rise as exercise intensity increases. In reality, stroke volume reaches a plateau at around 40–60% of maximum intensity, after which any further increase in cardiac output relies almost entirely on heart rate.
一个典型错误是声称每搏输出量会随运动强度持续上升。实际上，每搏输出量在最大强度的40–60%左右就会达到平台期，此后心输出量的进一步增加几乎完全依赖心率的提高。
Cardiac Output = Heart Rate × Stroke Volume
心输出量 = 心率 × 每搏输出量
Another common error involves the effect of training. Students often say resting stroke volume decreases in a trained athlete, when it actually increases. A trained heart pumps more blood per beat, allowing a lower resting heart rate.
另一个常见错误涉及训练的效果。学生常说训练有素的运动员安静时每搏输出量会减少，而实际上它是增加的。训练有素的心脏每搏泵出更多血液，使得安静心率降低。
When answering questions on cardiovascular drift, ensure you explain that during prolonged steady-state exercise, heart rate gradually rises while stroke volume declines due to dehydration and increased body temperature.
在回答关于心血管漂移的问题时，一定要解释：在进行长时间稳态运动时，由于脱水和体温升高，心率逐渐上升而每搏输出量下降。
3. Muscle Contractions: Concentric, Eccentric and Isometric | 肌肉收缩：向心、离心与等长
CIE examiners frequently test the three types of muscle contraction, often asking students to identify the type occurring during a specific movement phase. Concentric contraction involves muscle shortening under tension; eccentric contraction involves muscle lengthening under tension; isometric contraction involves no change in muscle length.
CIE考官经常测试三种肌肉收缩类型，常要求学生识别特定动作阶段发生的收缩类型。向心收缩是肌肉在张力下缩短；离心收缩是肌肉在张力下伸长；等长收缩是肌肉长度不变。
A prevalent error is thinking that eccentric contraction means the muscle relaxes. In reality, the muscle is active and controlling the movement, such as the quadriceps when lowering the body during a squat. Another mistake is confusing the bicep curl: students often say the upward phase is eccentric—it is concentric.
一个普遍错误是认为离心收缩意味着肌肉放松。实际上，肌肉是主动发力并控制动作的，例如深蹲下放时股四头肌的工作。另一个错误是混淆二头弯举：学生常说向上阶段是离心收缩，其实那是向心收缩。
Remember this tip: in the lifting phase of a bicep curl, the bicep shortens (concentric); in the lowering phase, the bicep lengthens but remains under tension (eccentric). Isometric occurs in a plank or wall sit where the muscle stays the same length.
记住这个技巧：二头弯举举起阶段，二头肌缩短（向心）；下放阶段，二头肌伸长但仍保持张力（离心）。平板支撑或靠墙静蹲中肌肉长度不变，发生的是等长收缩。
| Contraction Type | Muscle Length Change | Example |
|---|---|---|
| Concentric | Shortens | Upward phase of bicep curl |
| Eccentric | Lengthens | Downward phase of squat |
| Isometric | No change | Plank hold |
4. Joint Movements and Joint Classification | 关节运动与关节分类
Questions on joints require naming the type of synovial joint and the movements it allows. The shoulder and hip are ball-and-socket joints permitting flexion, extension, abduction, adduction, rotation and circumduction. The elbow and knee are hinge joints, mainly allowing flexion and extension.
关于关节的题目要求说出滑膜关节的类型及其允许的运动。肩关节和髋关节是球窝关节，允许屈、伸、外展、内收、旋转和环转。肘关节和膝关节是铰链关节，主要允许屈和伸。
A frequent mistake is to state that the elbow can perform rotation or abduction. Only the radio-ulnar joint near the elbow allows pronation and supination, not the elbow hinge itself. Another common error is confusing circumduction with rotation—circumduction is a combination of flexion, extension, abduction and adduction, creating a cone-shaped movement.
一个常见错误是声称肘关节可以做旋转或外展。肘关节附近的桡尺关节允许旋前和旋后，但肘关节铰链本身不能。另一个常见错误是将环转与旋转混淆——环转是屈、伸、外展和内收的复合运动，产生圆锥形轨迹。
When describing joint actions in a sporting movement, be precise. For example, in kicking a ball, the hip flexes and the knee extends; in the follow-through, the hip continues to flex. Avoid simply writing 'the leg moves' without naming the joints and actions.
在描述体育运动中的关节动作时要精准。例如踢球时，髋关节屈、膝关节伸；在随球动作中，髋关节继续屈。避免只写“腿移动”而不说出关节和动作名称。
A tip for exams: if a question asks 'Identify the joint action at the ankle during pointing the toes', the answer is plantar flexion, not just 'flexion'. Dorsiflexion brings the toes towards the shin.
考试提示：如果题目问“脚尖下压时踝关节的动作是什么”，答案是跖屈，而非简单的“屈曲”。背屈是将脚尖朝胫骨方向勾起。
5. Lever Systems and Mechanical Advantage | 杠杆系统与机械优势
CIE IGCSE PE requires knowledge of first-, second- and third-class levers. A common high-mark question asks students to draw and label a lever system seen in a specific sport, then state the mechanical advantage or disadvantage.
CIE IGCSE体育要求掌握一级、二级和三级杠杆。一个常见的高分题目是要求学生画出并标注某项运动中见到的杠杆系统，然后说明其机械优势或劣势。
The lever class depends on the relative positions of the fulcrum (F), effort (E) and load (L). A first-class lever has the fulcrum in the middle (e.g. neck nodding). A second-class lever has the load in the middle (e.g. standing on tiptoes – the ankle joint). A third-class lever has the effort in the middle (e.g. bicep curl).
杠杆的类型取决于支点（F）、力点（E）和阻力点（L）的相对位置。一级杠杆支点居中（如点头动作）。二级杠杆阻力点居中（如踮脚尖——踝关节）。三级杠杆力点居中（如二头弯举）。
The most frequent error is misidentifying the components in a sporting example. For the ankle during plantar flexion, many students draw a third-class lever when it is a second-class lever (the load is the body weight acting through the foot, the effort is the calf muscle, and the fulcrum is the ball of the foot). Another mistake is confusing the terms mechanical advantage and mechanical disadvantage. A second-class lever always provides mechanical advantage (effort arm longer), whereas most body levers are third-class and operate at a mechanical disadvantage for speed and range of motion.
最常见错误是在运动实例中错误归类部件。跖屈时的踝关节，许多学生画成三级杠杆，而它实际上是二级杠杆（阻力是通过脚传递的体重，力是小腿肌肉，支点是脚掌）。另一个错误是混淆机械优势和机械劣势。二级杠杆总是提供机械优势（力臂更长），而身体大多数杠杆是三级杠杆，以机械劣势工作以换取速度和运动范围。
Mechanical Advantage = Effort Arm / Load Arm
机械优势 = 力臂 / 阻力臂
In the bicep curl, the effort arm is very short, so a large effort is needed to lift a small load; this third-class lever gives a mechanical disadvantage but allows a large range of movement and fast contraction speed.
在二头弯举中，力臂很短，因此举起小阻力需要大力；这个三级杠杆产生机械劣势，但允许大范围运动和快速收缩。
6. Health-related Fitness Components: Confusing Endurance Types | 健康相关体能成分：混淆不同类型的耐力
Health-related fitness includes cardiovascular endurance, muscular endurance, flexibility, muscular strength and body composition. A very common mistake is mixing up cardiovascular endurance and muscular endurance when applied to sporting examples.
健康相关体能包括心血管耐力、肌肉耐力、柔韧性、肌肉力量和身体成分。一个很常见的错误是在运动实例中混淆心血管耐力和肌肉耐力。
Cardiovascular endurance is the ability of the heart and lungs to supply oxygen to working muscles over a prolonged period, as required by a marathon runner. Muscular endurance is the ability of a muscle or muscle group to perform repeated contractions without fatigue, such as in rowing or repeated leg extensions.
心血管耐力是心脏和肺部长时间为工作肌肉供氧的能力，如马拉松运动员所需。肌肉耐力是某块肌肉或肌肉群重复收缩而不疲劳的能力，如划船或反复伸腿。
Many students incorrectly identify the main fitness component for a 10 km run as muscular endurance. While leg muscles do work repeatedly, the primary demand is cardiovascular endurance because the activity is continuous and rhythmical, relying on the aerobic system. Another typical error is stating that flexibility is the same as suppleness without linking it to the range of motion around a joint.
许多学生错误地将10公里跑的主要体能成分认定为肌肉耐力。虽然腿部肌肉确实反复工作，但主要需求是心血管耐力，因为活动是连续的、有节奏的，依赖有氧系统。另一个典型错误是将柔韧性与柔软等同起来，而未将其与关节的活动范围联系起来。
To answer correctly, always match the component to the predominant physiological demand: if the activity lasts several minutes and uses large muscle groups rhythmically, cardiovascular endurance is key. If it involves repeated localised muscle actions with a resistance, muscular endurance is more relevant.
为了正确作答，始终将体能成分与主要的生理需求相匹配：如果活动持续数分钟并以有节奏的方式使用大肌肉群，则心血管耐力是关键；如果涉及在阻力下重复局部肌肉动作，则肌肉耐力更为相关。
7. Skill-related Fitness Components: Agility vs. Balance | 技能相关体能成分：灵敏与平衡
Agility, balance, coordination, power, reaction time and speed are the six skill-related components. CIE mark schemes often penalise students who use 'agility' when they mean 'balance', and vice versa.
灵敏、平衡、协调、爆发力、反应时间和速度是六项技能相关体能成分。CIE评分标准经常会惩罚那些将“灵敏”和“平衡”混淆的学生。
Agility is the ability to change the position of the body quickly and control the movement of the whole body. Balance is the ability to keep the body's centre of mass over the base of support, whether static (holding a handstand) or dynamic (maintaining control while moving).
灵敏是快速改变身体位置并控制全身运动的能力。平衡是在支撑面之上保持身体重心的能力，可以是静态的（如保持倒立）或动态的（如在移动时保持控制）。
A frequent error: a football dribble past defenders is often explained as needing balance, but the key component is agility because it involves rapid changes of direction. Conversely, a gymnast on a beam primarily needs balance. Another mistake is describing reaction time as simply 'reacting fast' without mentioning that it is the time between a stimulus and the start of movement.
常见错误：足球过人常被解释为需要平衡，但关键成分是灵敏，因为它涉及快速的方向改变。相反，平衡木上的体操运动员主要需要平衡。另一个错误是将反应时间简单描述为“反应快”，而没有提及它是从刺激到运动开始之间的时间。
When linking to training, use the correct test: the Illinois Agility Test measures agility, whereas the Stork Stand Test measures static balance. Do not mix them up in evaluation questions.
在联系训练时，使用正确的测试方法：伊利诺伊灵敏测试测量灵敏，而鹤立测试测量静态平衡。在评价问题中不要混淆。
8. Principles of Training: Specificity and Progressive Overload | 训练原则：专项性与渐进超负荷
Training principles, particularly specificity and progressive overload, are examined almost every session. Specificity means that training should be relevant and appropriate to the sport or activity to produce the desired adaptation. Progressive overload means gradually increasing the amount of exercise to continue making gains without causing injury.
训练原则，尤其是专项性和渐进超负荷，几乎每次考试都会涉及。专项性指训练应与运动或活动相关且适当，以产生所需的适应。渐进超负荷指逐渐增加运动量，以持续获得提升且不导致受伤。
A classic mistake is to define overload simply as 'working harder' without explaining how to apply it via the FITT principle (Frequency, Intensity, Time, Type). Progressive overload requires a planned increase in one or more of these variables over time. Another error is to list overload and progression as separate principles without linking them—progressive overload combines both ideas.
一个典型错误是将超负荷仅仅定义为“更努力地运动”，而没有解释如何通过FITT原则（频率、强度、时间、类型）来应用。渐进超负荷需要有计划地随时间增加这些变量中的一个或多个。另一个错误是将超负荷和渐进作为独立的原则列出而未联系起来——渐进超负荷将这两个概念结合在一起。
In application questions, if a runner wants to improve aerobic endurance, you should state that they might increase the frequency from 3 to 4 sessions per week, then increase the duration, and later add some interval training to increase intensity. Simply saying 'run more' lacks detail and loses marks.
在应用题中，如果一名跑步者想要提高有氧耐力，你应该说明他们可能将频率从每周3次增加到4次，然后增加持续时间，之后再加入间歇训练以提高强度。只说“多跑”缺乏细节，会失分。
Also be careful with specificity: training for a throwing event requires explosive power exercises, not long-distance jogging. Many students mistakenly prescribe jogging for all athletes, which violates the specificity principle.
还要注意专项性：投掷项目的训练需要爆发力练习，而不是长距离慢跑。许多学生错误地为所有运动员开出慢跑处方，这违反了专项性原则。
9. Training Methods: Interval Training and Target Zones | 训练方法：间歇训练与目标区间
Interval training involves periods of high-intensity work interspersed with recovery intervals. A common exam question asks to design an interval session for a specific athlete, or to explain the advantages of interval training over continuous training.
间歇训练包括高强度运动与恢复间歇相穿插。考试中常见的问题是要求为特定运动员设计一堂间歇训练课，或解释间歇训练相较于持续训练的优势。
Students frequently make mistakes when calculating target heart rate zones. The aerobic training zone is typically 60–80% of maximum heart rate (MHR), and the anaerobic zone is 80–90% MHR. Maximum heart rate can be estimated as 220 minus age.
学生在计算目标心率区间时经常出错。有氧训练区通常为最大心率（MHR）的60–80%，无氧区为MHR的80–90%。最大心率可用220减年龄估算。
MHR = 220 - age (years)
最大心率 = 220 - 年龄（岁）
A very common error is to apply the formula without adjusting for fitness level or to mislabel the zones. Some candidates think that the aerobic zone begins at 50% MHR, but CIE typically uses 60% as the lower threshold. Additionally, when applying the Karvonen formula which uses resting heart rate, many confuse the calculations. For IGCSE, the simple %MHR method is usually sufficient unless stated otherwise.
一个非常常见的错误是应用公式时没有根据体能水平进行调整，或错误标注区间。一些考生认为有氧区从50%MHR开始，但CIE通常以60%为下限。此外，在使用包含安静心率的卡沃内公式时，许多人计算错误。对于IGCSE而言，除非另有说明，通常简单的%MHR方法已足够。
In interval training design, students often fail to specify work-to-rest ratios. For anaerobic power, a ratio like 1:3 or 1:4 (e.g. 30 seconds sprint, 90–120 seconds rest) is appropriate. For aerobic interval training, the ratio may be 1:1 or 1:0.5. Generic answers without precise figures will not achieve top bands.
在设计间歇训练时，学生常未能具体说明运动与休息的比例。对于无氧功率，1:3或1:4的比例（如30秒冲刺，90–120秒休息）是合适的。对于有氧间歇训练，比例可以是1:1或1:0.5。没有精确数据的笼统答案无法获得高分档。
10. Sports Injuries: Sprains vs. Strains and R.I.C.E. | 运动损伤：扭伤与拉伤及 R.I.C.E.
Injury knowledge is a staple topic. Sprains and strains are frequently mixed up. A sprain is the stretching or tearing of ligaments (connect bone to bone). A strain is the stretching or tearing of muscles or tendons (connect muscle to bone).
损伤知识是必考主题。扭伤和拉伤经常被混淆。扭伤是韧带（连接骨与骨）的拉伸或撕裂。拉伤是肌肉或肌腱（连接肌肉与骨）的拉伸或撕裂。
The classic exam error: describing an ankle injury as a strain when the ligaments are damaged. Since the ankle injury often involves the ligaments on the outside, it is a sprain. Similarly, a hamstring injury is a strain because muscle fibres are torn.
典型的考试错误：当韧带受损时，将脚踝损伤描述为拉伤。由于脚踝损伤常常涉及外侧韧带，因此是扭伤。同样，腘绳肌损伤是拉伤，因为肌纤维撕裂。
R.I.C.E. treatment (Rest, Ice, Compression, Elevation) is another high-frequency topic. Common mistakes include confusing the order, omitting the purpose of each step, or forgetting to mention that ice should be applied for 20 minutes every 2–3 hours, not continuously. Also, elevation should position the injury above the heart level to reduce swelling through gravity.
R.I.C.E. 处置（休息、冰敷、加压、抬高）是另一个高频话题。常见错误包括顺序混淆、遗漏每一步的目的，或忘记提及冰敷应为每2–3小时敷20分钟，而非持续敷。此外，抬高应使伤处高于心脏水平，以利用重力减轻肿胀。
Students lose marks by writing general statements like 'put ice on it' without explaining that ice causes vasoconstriction, reducing blood flow and swelling, and that it should be wrapped in a cloth to prevent ice burns. Compression limits swelling; elevation aids venous return.
学生因写下“冰敷一下”这样笼统的陈述而失分，没有解释冰敷引起血管收缩，减少血流和肿胀，并应包裹在布中以防冻伤。加压限制肿胀；抬高有助于静脉回流。
11. Nutrition: Carbohydrate Loading and Hydration | 营养：碳水化合物负荷与补水
Nutrition questions often focus on carbohydrate loading for endurance events and the importance of hydration. Carbohydrate loading is a strategy used to maximise glycogen stores before a long-duration event, typically involving a tapering of training while increasing carbohydrate intake in the days before competition.
营养题目经常聚焦于耐力项目的碳水化合物负荷以及补水的重要性。碳水化合物负荷是一种用于在长时间运动前最大化糖原储备的策略，通常包括在比赛前几天逐渐减少训练量同时增加碳水化合物摄入。
A common mistake is explaining carbohydrate loading as simply eating a large pasta meal the night before. The full process involves depletion of glycogen stores 7 days before, followed by a high-carbohydrate diet (about 70–80% of total energy) and reduced training 3–4 days before, then a pre-competition meal. Another error is recommending carbohydrate loading for a 100 m sprinter, where it would provide no benefit and could cause weight gain.
一个常见错误是将碳水化合物负荷解释为只是赛前一晚吃一顿大餐意大利面。完整的过程包括赛前7天耗尽糖原，随后在赛前3–4天进行高碳水化合物饮食（约占总能量的70–80%）并减少训练，再加上赛前餐。另一个错误是为100米短跑运动员推荐碳水化合物负荷，这毫无益处且可能导致体重增加。
Hydration questions demand accuracy on the effects of dehydration: increased heart rate, reduced stroke volume, impaired thermoregulation, and decreased cognitive function. Students often forget that a loss of even 2% body weight via fluid can impair performance. Electrolyte balance is also vital; drinking water alone may not replace lost sodium, potentially causing hyponatremia.
补水问题要求准确说明脱水的影响：心率加快、每搏输出量减少、体温调节受损和认知功能下降。学生经常忘记即使通过流汗失去体重的2%也会损害运动表现。电解质平衡同样重要；单喝水可能无法补充流失的钠，有引起低钠血症的风险。
In exam answers, always link nutritional strategies to the type of activity, intensity and duration. A team sport player may need quick-acting carbohydrates at half-time, not full carbohydrate loading.
在考试答案中，始终将营养策略与活动类型、强度和持续时间联系起来。团体项目运动员可能在中场时需要快速作用的碳水化合物，而不是完全的碳水化合物负荷。
