1. Heart Structure & The Pathway of Blood | 心脏结构与血液循环路径

The heart is a four-chambered pump: right atrium, right ventricle, left atrium, left ventricle. Deoxygenated blood returns from the body via the vena cava into the right atrium, passes into the right ventricle, and is pumped through the pulmonary artery to the lungs. In the lungs, gas exchange occurs; oxygenated blood travels back via the pulmonary vein into the left atrium, moves to the left ventricle, and is then ejected through the aorta to the rest of the body. The septum separates the two sides, preventing mixing of oxygenated and deoxygenated blood.

心脏是一个四腔泵：右心房、右心室、左心房、左心室。缺氧血从身体经腔静脉回到右心房，进入右心室，再被泵入肺动脉到达肺部。在肺部进行气体交换后，含氧血经肺静脉返回左心房，进入左心室，然后通过主动脉被输送到全身。室间隔将左右两侧分开，防止含氧血与缺氧血混合。

A classic mistake is to label the left and right sides of the heart incorrectly on a diagram as if looking at it from the front. Students often switch them: the heart’s own left and right are the opposite of the viewer’s left and right. The labels ‘left atrium’ and ‘left ventricle’ appear on the right-hand side of a standard diagram. Another common error is writing that the pulmonary artery carries oxygenated blood – it is the only artery carrying deoxygenated blood. Similarly, the pulmonary vein carries oxygenated blood, which is unique for a vein.

一个经典错误是在心形图上按照观察者的视角标注左右，把心脏自身的左侧和右侧搞反。心脏的“左心房”“左心室”在标准图上位于图的右侧。另一个常见错误是说肺动脉输送含氧血——它是唯一输送缺氧血的动脉。同理，肺静脉输送含氧血，这在静脉中是独一无二的。

Vessel	Blood type	Direction of flow
Vena cava	Deoxygenated	Body → Right atrium
Pulmonary artery	Deoxygenated	Right ventricle → Lungs
Pulmonary vein	Oxygenated	Lungs → Left atrium
Aorta	Oxygenated	Left ventricle → Body

2. Mechanics of Breathing & Lung Volumes | 呼吸机制与肺容量

During inspiration, the diaphragm contracts and flattens, while the external intercostal muscles contract to lift the rib cage up and out. This increases thoracic cavity volume and decreases pressure, drawing air in. At rest, expiration is passive: the diaphragm and intercostals relax, the rib cage drops, and elastic recoil pushes air out. During exercise, internal intercostals and abdominal muscles contract to force a more rapid and deeper expiration.

吸气时，膈肌收缩并变平，外肋间肌收缩将胸廓向上向外提拉。胸腔容积增大，压力降低，空气被吸入。安静状态下呼气是被动的：膈肌和肋间肌舒张，胸廓下降，弹性回缩将空气推出。运动时，内肋间肌和腹肌收缩，迫使呼气更快、更深。

One of the most heavily examined concepts is the difference between tidal volume, vital capacity, expiratory reserve volume, inspiratory reserve volume and residual volume. Students frequently confuse tidal volume with vital capacity. Tidal volume is the amount of air breathed in or out per breath at rest (~0.5 L). Vital capacity is the maximum amount of air that can be exhaled after a maximum inhalation. Another mistake is forgetting that residual volume cannot be expelled and stays in the lungs even after a maximum breath out – this prevents lung collapse.

考查最密集的概念之一是潮气量、肺活量、补呼气量、补吸气量和残气量的区别。学生经常将潮气量与肺活量混淆。潮气量是安静状态下每次吸入或呼出的气体量（约0.5升）。肺活量是最大吸气后尽力呼出的最大气量。另一个错误是忘记残气量无法被呼出，即使用力呼气后仍留在肺中——这可以防止肺泡塌陷。

A spirometer trace interpretation question often asks you to identify these volumes. Misreading the y‑axis (volume) or confusing inspiratory reserve volume with expiratory reserve volume loses easy marks. Reproduce the shape of a spirogram and label tidal volume, vital capacity and breathing rate clearly.

肺活量计图形分析题经常要求识别这些容量。读错纵轴（体积），或者把补吸气量与补呼气量搞混，会丢掉简单的分数。要能够画出呼吸描记图的形状，并清晰标注潮气量、肺活量和呼吸频率。

3. Lever Systems & Mechanical Advantage | 杠杆系统与机械效益

Every lever has three components: fulcrum (pivot), effort (force applied), and load (resistance being moved). In the human body, joints act as fulcrums, muscles provide effort, and the weight of the body part plus any external weight acts as the load. The three classes of lever are defined by the central component in the sequence: first class has the fulcrum in the middle (e.g. nodding the head), second class has the load in the middle (e.g. standing on tiptoes), and third class has the effort in the middle – the most common lever in the body (e.g. elbow flexion in a bicep curl).

每个杠杆有三个要素：支点（转轴）、动力（施加的力）和阻力（被移动的重量）。在人体中，关节是支点，肌肉提供动力，身体环节的重量加上任何外部负重则构成阻力。三类杠杆由中间组分决定：一类杠杆支点在中间（如点头），二类杠杆阻力在中间（如踮脚尖），三类杠杆动力在中间——这是人体中最常见的杠杆（如肱二头肌弯举时的屈肘）。

Students regularly misclassify a standing calf raise. Because you push down through the ball of the foot, many assume the ball is the fulcrum. In reality, the fulcrum is the metatarsophalangeal joints, the load is body weight acting through the ankle, and the effort comes from the gastrocnemius pulling on the heel. The load lies between the fulcrum and the effort – making it a second-class lever. Getting this wrong then leads to an incorrect description of mechanical advantage. A second-class lever always has a mechanical advantage greater than 1, meaning a relatively small effort can move a large load, which explains why you can lift your entire body weight on one foot.

学生经常误判站立提踵这个动作。因为是用前脚掌下压，很多人以为前脚掌是支点。实际上，支点是跖趾关节，阻力是经踝关节作用的体重，动力来自腓肠肌向下牵拉跟骨。阻力位于支点和动力之间——所以这是一个二类杠杆。如果这个判断错了，机械优势的描述也会跟着错。二类杠杆的机械优势总是大于1，意味着较小的动力可以移动较大的负荷，这就解释了为什么单脚就能提起全身重量。

Third-class levers are sometimes incorrectly thought to be inefficient because their mechanical advantage is less than 1. An examiner expects you to point out that they allow a large range of movement and high speed at the end of the lever, which is essential for sporting actions such as throwing or kicking.

有些人错误地认为三类杠杆效率低，因为其机械优势小于1。考官期望你指出，三类杠杆可以让杠杆末端产生大幅度的运动和高速移动，这对投掷、踢球等运动动作至关重要。

4. Planes & Axes of Movement | 平面与运动轴

Planes are imaginary flat surfaces running through the body, and axes are the lines around which rotation occurs. Sagittal plane divides the body into left and right, and flexion/extension movements occur in this plane around a frontal (mediolateral) axis. Frontal plane divides front and back; abduction/adduction occur around a sagittal (anteroposterior) axis. Transverse plane divides upper and lower; rotation occurs around a longitudinal (vertical) axis.

平面是贯穿身体的假想平坦面，轴是旋转发生所围绕的线。矢状面将身体分为左右两部分，屈伸动作发生在这个平面内，绕额状轴（冠状轴）转动。额状面将身体分为前后两部分，外展/内收绕矢状轴（前后轴）转动。水平面将身体分为上下两部分，旋转绕垂直轴（纵轴）转动。

The most frequent error is pairing the wrong axis with a plane. Students confidently state that a somersault (sagittal plane, frontal axis) is correct, but then say a cartwheel uses the frontal plane and sagittal axis – which is correct, but many mix the axis with the transverse plane. Use these three classic examples to lock the pairings: sprinting knee drive → sagittal plane, frontal axis; star jump → frontal plane, sagittal axis; discus spin → transverse plane, longitudinal axis. If you can explain each pairing, you will be able to tackle any sporting example in the exam.

最常见的错误是给平面配错轴。学生能自信地说出前空翻是矢状面、额状轴，但说到侧手翻时——正确的配对是额状面、矢状轴——许多人却把它跟水平面混淆了。用下面这三个经典例子来记牢配对：冲刺抬膝→矢状面、额状轴；开合跳→额状面、矢状轴；铁饼旋转→水平面、垂直轴。如果能解释每一组配对，就能应对考试中任何运动实例。

5. Principles of Training: SPORT & FITT | 训练原则：SPORT 与 FITT

SPORT stands for Specificity, Progression, Overload, Reversibility, and Tedium (boredom). Specificity means training must match the demands of the sport or activity. Progression requires gradually increasing the challenge. Overload is pushing the body beyond its normal limits, described by the FITT variables (Frequency, Intensity, Time, Type). Reversibility warns that fitness gains are lost when training stops. Tedium reminds us to vary training to maintain motivation.

SPORT 代表专项性、渐进性、超负荷、可逆性和无聊。专项性指训练必须匹配运动或活动的需求。渐进性要求逐步增加挑战。超负荷是让身体超出日常负荷极限，可用 FITT 变量（频率、强度、时间、类型）来描述。可逆性警告说训练一旦停止，已获得的身体素质会消退。无聊提醒我们要变换训练内容以保持动力。

In extended writing questions, students often list the principles without applying them to the given scenario. For example, if a question describes a runner trying to improve her 1500 m time, you must explain how specificity applies – she needs to focus on the aerobic energy system and include interval training at race pace, rather than simply doing heavy weightlifting. Similarly, apply overload by stating exactly which FITT variable should change: perhaps increase intensity by running at 80% max heart rate instead of 70%, or increase time from 30 to 45 minutes. A vague statement like ‘she should train harder’ will not score marks.

在写作拓展题时，学生常常只会罗列原则，而不会把它们应用到所给场景中。例如，题目描述一位跑者试图提高1500米成绩，你必须解释专项性如何运用——她需要着重有氧供能系统，在训练中加入比赛配速的间歇跑，而不是简单地做大量举重。同理，运用超负荷时要明确说明改变哪个 FITT 变量：可能是将强度从70%最大心率提高到80%，或者将时间从30分钟延长到45分钟。只说“她应该更努力训练”这样模糊的表述是无法得分的。

6. Training Methods & Calculating Intensity | 训练方法与强度计算

Continuous training involves steady-state exercise without rest, mainly developing aerobic endurance. Interval training alternates periods of high-intensity work with recovery, improving both aerobic and anaerobic fitness. Circuit training uses stations of different exercises to develop multiple components of fitness. Fartlek training blends continuous and interval elements with changes in speed and terrain. Weight training uses resistance to build strength, muscular endurance or power.

持续训练法是无间歇的稳态运动，主要发展有氧耐力。间歇训练法交替进行高强度工作与恢复，同时提升有氧和无氧能力。循环训练法借助不同练习的站点，发展多种体能要素。法特莱克训练法将持续训练与间歇元素融合，伴有速度和地形的变化。重量训练利用阻力来增强力量、肌耐力或爆发力。

Calculating target heart rate zones often causes errors. The basic formula is: Maximum Heart Rate (MHR) = 220 – age. For aerobic training, the target zone is 60–80% of MHR. The Karvonen formula adds resting heart rate for more accuracy: Target HR = Resting HR + (desired intensity % × Heart Rate Reserve), where Heart Rate Reserve = MHR – Resting HR. In exam questions, students sometimes multiply the percentage directly by the resting heart rate instead of heart rate reserve, or forget to add back the resting heart rate. Always show the calculation step by step – the mark scheme rewards working.

计算目标心率区间经常出错。基本公式是：最大心率 (MHR) = 220 – 年龄。有氧训练的目标区间是最大心率的60–80%。卡沃宁公式引入静息心率以提高精度：目标心率 = 静息心率 + (期望强度百分比 × 心率储备)，其中心率储备 = 最大心率 – 静息心率。考试中，学生有时直接把百分比乘以静息心率而不是心率储备，或者忘记加上静息心率。一定要逐步展示计算过程——评分方案会给步骤分。

Another common pitfall is confusing the benefits of altitude training. Training at high altitude stimulates natural EPO production, increasing red blood cell count and oxygen-carrying capacity when back at sea level. However, the potential downsides include altitude sickness, reduced training intensity due to lower oxygen, and the temporary nature of the adaptations. Saying altitude training directly improves performance at altitude is often a red herring; the exam wants the link to sea-level endurance improvements.

另一个常见陷阱是混淆高原训练的好处。在高原训练会刺激体内自然 EPO 的产生，增加红细胞数量，回到平原时提高携氧能力。但潜在的不利因素包括高原病、因氧气稀薄导致的训练强度下降，以及这些适应的暂时性。如果回答成高原训练能直接改善在高原上的表现，往往是陷阱；考试想要的是它与平原地区耐力提升的联系。

7. Skill Classification & Continua | 技能分类与连续体

Skills are not simply ‘open’ or ‘closed’ – they are placed on several continua. The main ones are: open–closed (environmental stability), gross–fine (muscle groups used), self-paced–externally paced (timing control), discrete–serial–continuous (clear beginning and end), high organisation–low organisation (sub-routines separable), and simple–complex (decision-making demand). A set pass in volleyball, for instance, tends towards open, gross, externally paced, serial and low organisation.

技能并不能简单地分为“开放”或“闭合”——它们分布在多个连续体上。主要的连续体有：开放–封闭（环境稳定性）、粗大–精细（参与的肌群）、自定节奏–外部节奏（控时方式）、分立–序列–连续（有无明确起止点）、高组织–低组织（子程序是否可拆分）、简单–复杂（决策需求）。排球中的上手传球，就偏向于开放、粗大、外部节奏、序列和低组织。

Examiners regularly report that students place a skill at the extreme end of a continuum when it realistically sits somewhere between. For example, a tennis serve in a closed environment (practice with a ball machine) is not ‘completely closed’; the server still has to adjust to small variations. Similarly, a chest pass in netball during a game is influenced heavily by opponents’ positions, so it cannot be placed at the extreme closed end. Use the stem ‘Mostly…’ or ‘Towards the … end’ for higher marks. Also, be prepared to justify why you moved a skill along a continuum if the context changes – a penalty kick in football moves from externally paced and open (crowd noise, goalkeeper movement) towards more closed and self-paced if the scenario is an empty training ground.

阅卷官经常指出，学生把技能放在连续体的极端位置，而实际上它只处于中间某一区域。例如，在封闭环境（用发球机练习）下的网球发球并不是“完全封闭”的；发球者仍需适应微小的变化。同样，比赛中的篮网球胸前传球深受对手站位的影响，因此不能放在极端的封闭端。使用“主要偏向……”或“处于……端”这类表述可以拿到更高分数。另外，如果情境发生变化，还要准备好解释为什么技能在连续体上移动了——有观众噪音、守门员变动的足球点球，会从外部节奏、开放端，向更封闭、自定节奏的方向移动，如果情景改为无人训练场的话。

8. Types of Feedback & Goal Setting | 反馈类型与目标设定

Feedback can be intrinsic (through the senses, e.g. kinaesthetic feeling of a golf swing) or extrinsic (from outside sources, e.g. a coach’s comment). It can be concurrent (during performance) or terminal (after performance). Knowledge of results focuses on the outcome (‘you scored 8 out of 10’), while knowledge of performance focuses on technique quality (‘your follow-through was too short’). Beginners benefit more from extrinsic, terminal and knowledge of results; experts use intrinsic and concurrent feedback more effectively.

反馈可以分为内在（通过感官，如高尔夫挥杆的动觉感受）或外在（来自外部，如教练的评语）。它可以是并发（表现过程中）或终末（表现后）的。结果知识与结果相关（“你10次中了8次”），而表现知识与技术质量相关（“你的随挥动作太短了”）。初学者更多受益于外在的、终末的和结果知识反馈；专家则更有效地使用内在和并发反馈。

The SMART goal-setting principle (Specific, Measurable, Achievable/Agreed, Realistic/Relevant, Time-bound) is frequently tested, but students lose marks by writing ‘Achievable’ as ‘accessible’ or forgetting to explain how each element applies. A mark-worthy answer for a swimmer wanting to improve 100 m freestyle time might be: ‘Specific – complete 8 × 50 m intervals at target pace with 30 s rest; Measurable – record split times; Achievable – based on current PB and training data; Relevant – mimics race demands; Time-bound – achieve by the county championships in six weeks.’ Never just write the letters out.

SMART 目标设定原则（具体的、可衡量的、可实现的/协商一致的、现实的/相关的、有时间限制的）经常考，但学生因把“可实现的”写成“可接近的”，或者忘记解释每个要素如何应用而失分。对于一个想提高100米自由泳成绩的游泳运动员来说，能拿分的答案可能是：“具体的——按目标配速完成8×50米间歇，组间休息30秒；可衡量的——记录分段计时；可实现的——基于当前个人最好成绩和训练数据；相关的——模拟比赛需求；有时间限制的——在六周后的郡锦标赛前达到。”千万不要只把字母写出来了事。

9. Components of Health & Fitness | 健康与健身的组成部分

Health-related components include cardiovascular endurance, muscular endurance, muscular strength, flexibility, and body composition. Skill-related (motor fitness) components are agility, balance, coordination, power, reaction time and speed. A short mark-scheme favourite is linking body composition to the ratio of fat mass to lean mass, not simply ‘how much you weigh’. BMI is mentioned in some specifications but note it does not distinguish between muscle and fat.

健康相关要素包括心血管耐力、肌耐力、肌力、柔韧性和身体成分。技能相关（运动素质）要素包括灵敏性、平衡、协调、爆发力、反应时间和速度。评分方案中喜欢的一点是将身体成分定义为脂肪质量与去脂体重的比例，而不是单纯的“你有多重”。部分考纲提及 BMI，但要注意它不能区分肌肉和脂肪。

Students often list agility when the scenario calls for balance, or mix up power with strength. Power is the product of strength and speed (work done per unit time), tested via a vertical jump or Wingate test. Strength is maximal force a muscle can exert, tested via a one-rep max. In a question about a gymnast holding a handstand, balance and static strength are key – agility is not required. Similarly, a sprinter’s start requires power and reaction time, not necessarily flexibility. Context decides which components are relevant.

学生常常在需要平衡的情境中列出灵敏性，或把爆发力与力量混为一谈。爆发力是力量与速度的乘积（单位时间内做功多少），可通过纵跳或 Wingate 测试来测量。力量是肌肉能产生的最大力，用1RM测试来衡量。在关于体操运动员倒立的题目中，平衡和静态力量是关键——灵敏性并不需要。同理，短跑运动员的起跑需要爆发力和反应时间，不一定用到柔韧性。情境决定哪些要素是相关的。

10. Data Presentation & Interpretation | 数据呈现与解读

Data in Physical Education can be quantitative (numerical, e.g. heart rate, times) or qualitative (descriptive, e.g. coach observations, questionnaires). Graphs such as bar charts, line graphs and scattergrams are used to present data. A scattergram with a line of best fit can show a correlation, but many candidates erroneously state that correlation proves causation. ‘There is a positive correlation between reaction time and sprint finish time’ does not mean one causes the other.

体育中的数据可以是定量（数字的，如心率、时间）或定性（描述的，如教练观察、问卷调查）。条形图、折线图和散点图等图表用于呈现数据。带有最佳拟合线的散点图可以显示相关性，但许多考生错误地认为相关性就意味着因果关系。“反应时间与短跑完赛时间呈正相关”并不意味着一方导致另一方。

A common exam question provides a table of results and asks you to calculate mean, median, mode and range. Mean is the average, median is the middle value when data is ordered, mode is the most frequent value, and range is the difference between highest and lowest values. Miscalculations occur when students do not reorder the data set for the median, or forget that the range is a single value (not ’24–36′ but ’12’). Also, when interpreting a graph, always quote specific data points to support your analysis, e.g. ‘The graph shows a decrease in 10 m sprint time from 1.95 s to 1.82 s after the 8‑week training programme.’

常见的考题是给出一组数据表格，要求计算平均数、中位数、众数和极差。平均数是算数平均值，中位数是按顺序排列后位于中间的值，众数是出现频率最高的值，极差是最大值与最小值之差。计算错误通常是因为学生没有为重求中位数而重新排列数据，或者忘记极差是一个单一数值（不是“24–36”，而是“12”）。此外，解读图表时，务必引用具体数据点来支撑分析，例如“图表显示经过8周训练计划后，10米冲刺时间从1.95秒降至1.82秒”。
