Year 7 CAIE Physical Education builds the foundation for understanding how the body moves, stays healthy and performs in sport. This article highlights the topics that appear most often in assessments and breaks down the common mistakes students make, so you can focus your revision where it matters most.
Year 7 CAIE 体育为学生理解身体如何运动、保持健康以及提升运动表现打下基础。本文梳理了评估中出现频率最高的考点，并详细分析了学生常犯的错误，帮助你精准复习。
1. Health-Related Components of Fitness | 健康相关的体适能要素
Health-related fitness includes cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition. These components are directly linked to overall health and are tested frequently through definitions and application to sports.
健康相关体适能包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。这些要素与整体健康直接相关，常通过定义和在运动中的应用进行考查。
A very common mistake is to confuse muscular strength (the maximum force a muscle can produce in one effort) with muscular endurance (the ability to repeat a movement for a long time without getting tired). For example, a weightlifter performing a single heavy lift demonstrates strength, while a rower maintaining strokes over 2000 metres relies on endurance. In multiple‑choice questions, students often tick ‘muscular strength’ when the description involves repeated actions over time.
一个非常常见的错误是混淆肌肉力量（肌肉单次收缩产生的最大力量）和肌肉耐力（长时间重复动作而不疲劳的能力）。例如，举重运动员完成一次大重量试举展示的是力量，而赛艇运动员在2000米全程保持划桨依赖的是耐力。在选择题中，当题干描述涉及长时间重复动作时，学生常会错选“肌肉力量”。
Another tricky area is understanding body composition as more than just ‘weight’. Body composition refers to the percentage of fat, muscle and bone in the body. Make sure you can explain why two people with the same height and weight may have very different fitness levels.
另一个容易出错的地方是认为身体成分仅仅就是“体重”。身体成分指的是人体内脂肪、肌肉和骨骼的比例。要能解释为什么身高体重相同的两个人，健康水平可能相差很大。
2. Skill-Related Components of Fitness | 技能相关的体适能要素
Agility, balance, coordination, power, reaction time and speed are the six skill‑related components. These are essential for performing well in specific sports and are often examined by matching the component to a sporting action.
敏捷、平衡、协调、爆发力、反应时间和速度是六项技能相关的体适能要素。它们对在特定运动中表现出色至关重要，常以“将要素与运动动作配对”的形式考查。
The most frequent errors happen between agility and speed, and between power and strength. Agility is the ability to change direction quickly while maintaining control – think of a footballer dribbling past defenders. Speed is simply how fast you can move from A to B. Power is a combination of strength and speed, such as a jump shot in basketball, not pure strength alone. In exams, students often label a sprint start as ‘agility’ because the athlete looks quick, but it’s mainly speed and power.
出错频率最高的是敏捷与速度的混淆，以及爆发力与力量的混淆。敏捷是迅速变向同时保持控制的能力——想象一名足球运动员带球过人的场景。速度仅仅是指从一点到另一点移动的快慢。爆发力是力量与速度的结合，例如篮球中的跳投，而不是单纯的肌肉力量。考试中，学生常因为运动员动作很快就把短跑起跑归为“敏捷”，但实际主要涉及速度和爆发力。
Remember, coordination is the ability to use two or more body parts together smoothly, like eye‑hand coordination in catching a ball. Balance can be static (holding a handstand) or dynamic (maintaining control while moving). A table listing each component with a clear sporting example can be a powerful revision tool.
请记住，协调是同时流畅地使用两个或多个身体部位的能力，比如接球时的手眼协调。平衡可以是静态平衡（如保持手倒立）或动态平衡（在移动中维持控制）。制作一个包含各要素及对应运动示例的表格，会是很有用的复习工具。
3. The Skeletal System: Functions and Types of Bones | 骨骼系统：功能与骨骼类型
The skeleton has five main functions: support, protection, movement, mineral storage and blood cell production. Questions often ask students to explain how a specific function helps during sport – for instance, how the cranium protects the brain in rugby.
骨骼系统有五大主要功能：支撑、保护、运动、矿物质储存和血细胞生成。考题常要求学生解释某一功能在运动中如何发挥作用——例如，在橄榄球运动中颅骨如何保护大脑。
When classifying bones, students confuse long bones and flat bones. Long bones like the femur and humerus are used as levers for movement and produce red blood cells. Flat bones like the cranium, ribs and pelvis provide protection and have a large surface area for muscle attachment. A common mistake is calling the clavicle a long bone; it is actually a flat bone despite its shape. The vertebrae are irregular bones, another frequently tested detail.
在进行骨骼分类时，学生会混淆长骨和扁骨。股骨和肱骨等长骨作为运动杠杆，并产生红细胞。颅骨、肋骨和骨盆等扁骨则提供保护，且有较大的表面积供肌肉附着。常见的错误是把锁骨称为长骨；尽管形状细长，但它实际上是扁骨。椎骨属于不规则骨，这也是经常被考查的细节。
Be ready to label major bones on a diagram: cranium, clavicle, scapula, humerus, ribs, sternum, vertebrae, pelvis, femur, patella, tibia, fibula. Spelling these correctly is often a source of lost marks.
要能在示意图上标注主要骨骼：颅骨、锁骨、肩胛骨、肱骨、肋骨、胸骨、椎骨、骨盆、股骨、髌骨、胫骨和腓骨。拼写正确往往是失分点。
4. Joint Types and Movements | 关节类型与运动
Freely movable (synovial) joints dominate the Year 7 syllabus. The three types you must know are hinge joints (e.g. knee, elbow), ball‑and‑socket joints (e.g. shoulder, hip) and pivot joints (e.g. neck, between radius and ulna). Each allows specific movements.
可动关节（滑膜关节）是 Year 7 课程的重点。必须掌握的三种类型是：铰链关节（如膝关节、肘关节）、球窝关节（如肩关节、髋关节）和枢轴关节（如颈部、桡尺关节）。每一种关节允许特定的运动。
A classic exam error is mixing up the movements allowed at hinge and ball‑and‑socket joints. Hinge joints only allow flexion and extension – like opening and closing a door. Ball‑and‑socket joints allow flexion, extension, abduction, adduction, rotation and circumduction. Students often write that the knee can perform rotation, which is incorrect and can lead to a significant mark deduction. The neck’s pivot joint allows rotation (shaking your head ‘no’).
一个典型的考试错误是混淆铰链关节和球窝关节允许的运动。铰链关节只允许屈伸——就像开门和关门。球窝关节则允许屈、伸、外展、内收、旋转和环转。学生常写膝关节能做旋转运动，这是错误的，会导致严重扣分。颈部的枢轴关节允许旋转（表示 “不”的摇头动作）。
Be careful with the terms ‘abduction’ (moving a limb away from the midline of the body) and ‘adduction’ (bringing it back toward the midline). Think of ‘abduction’ as taking away, and ‘adduction’ as adding to the body. Tables linking joint type, location, movement and sporting action are highly exam‑relevant.
注意区别“外展”（肢体远离身体中线）和“内收”（肢体回到中线）。可以想象 “abduction” 带有“带走”的意思，“adduction” 则是“加入”身体。将关节类型、位置、运动形式和运动动作联系起来制作的表格，与考试高度相关。
5. Major Muscles and Antagonistic Pairs | 主要肌肉与拮抗肌对
Key muscles to learn are the biceps, triceps, quadriceps, hamstrings, gastrocnemius, gluteals, latissimus dorsi and abdominals. Muscles can only pull; they work in pairs to create movement at a joint – these are called antagonistic pairs.
需要掌握的主要肌肉有：二头肌、三头肌、四头肌、腘绳肌、腓肠肌、臀肌、背阔肌和腹肌。肌肉只能收缩拉，无法主动推。它们成对工作以在关节处产生运动，这就是拮抗肌对。
The most frequent error is misidentifying the agonist (prime mover) and antagonist during a movement. When you flex your elbow to curl a weight, the biceps contracts and is the agonist; the triceps relaxes and is the antagonist. When you extend the elbow to lower the weight, the roles swap: triceps becomes the agonist. Students often label the triceps as the agonist during both phases, or they forget to state clearly which muscle is contracting.
最常见的错误是在某一运动中错误识别主动肌（原动肌）和拮抗肌。做弯举动作屈肘时，二头肌收缩，是主动肌；三头肌放松，是拮抗肌。当伸展肘部下放重量时，角色互换：三头肌成为主动肌。学生经常在两个阶段都标注三头肌为主动肌，或者没有清楚说明哪块肌肉在收缩。
When analysing kicking a football, the quadriceps act as agonist to straighten the knee, and the hamstrings are antagonist. A well‑labelled diagram of the upper arm and upper leg with antagonistic muscles clearly indicated is invaluable for revision.
分析踢足球动作时，四头肌是主动肌，伸直膝关节，腘绳肌是拮抗肌。一幅清晰标注上臂和大腿拮抗肌的示意图，对复习极有帮助。
6. Phases and Benefits of a Warm‑Up | 热身的阶段与益处
A proper warm‑up has three stages: pulse raiser, stretching and sport‑specific drills. Knowing the correct order and the reason for each stage is a high‑frequency assessment target.
一次完整的热身包含三个阶段：心率提升、拉伸和专项运动练习。清楚每个阶段的正确顺序及其原因，是一个高频考点。
Many students make mistakes with the order. Some think static stretching should come first, but intense static stretching on cold muscles can cause injury. The correct sequence is: (1) light jogging or skipping to gradually raise heart rate and increase blood flow to muscles, (2) dynamic stretches that move joints through their range, and (3) skills practice, such as short passes in football or lay‑up lines in basketball, which primes the neuromuscular system for the main activity.
很多学生在顺序上出错。有人认为应先做静态拉伸，但在肌肉没有充分活动时进行强烈的静态拉伸可能导致受伤。正确顺序是：（1）通过慢跑或跳跃逐渐提升心率，增加肌肉血流量；（2）进行动态拉伸，使关节在全幅度内活动；（3）进行技能练习，如足球中的短传或篮球中的上篮练习，这能让神经肌肉系统为主体活动做好准备。
Other common errors include forgetting to explain benefits in physiological terms, such as increased oxygen delivery, reduced risk of injury, and improved mental readiness. Simply writing “it makes you warm” will not gain full marks.
其他常见错误包括没有从生理角度解释益处，比如增加氧气输送、降低受伤风险以及提高心理准备。仅仅写 “让身体变暖” 无法得到满分。
7. Heart Rate and Measuring Exercise Intensity | 心率与运动强度测量
Understanding resting heart rate, maximum heart rate (MHR) and recovery rate is vital. The simple formula used at Year 7 level is:
MHR ≈ 220 – age
and working heart rate during exercise is often given as a percentage of MHR.
理解静息心率、最大心率（MHR）和恢复心率至关重要。Year 7 阶段使用的简单公式是：
最大心率 ≈ 220 – 年龄
运动时的目标心率通常表示为最大心率的百分比。
A very common mistake is thinking a lower heart rate during exercise is always better. Students may assume that if their friend has a lower exercising heart rate, the friend is fitter. While a lower resting heart rate generally indicates better cardiovascular fitness, during exercise the intensity dictates the heart rate. At the same workload, a fitter person will often have a lower heart rate, but this is relative. Confusing resting and exercising heart rate is a trap. Also, forgetting that recovery rate – how fast the heart rate drops after exercise – is a strong indicator of fitness often costs marks.
一个极常见的错误是认为运动中较低的心率总是更好。学生可能会断言，如果朋友的运动心率更低，就说明朋友更健康。虽然较低的静息心率通常代表更好的心血管健康，但在运动中心率是由强度决定的。在相同负荷下，体能更好的人心率通常较低，但这是相对的。混淆静息心率和运动心率是一个陷阱。此外，忘记恢复心率——运动后心率下降的速度——是衡量体能的重要指标，经常导致失分。
When calculating MHR for a 12‑year‑old, 220 – 12 = 208 bpm. If asked to find 60% of MHR, students sometimes miscalculate or forget the units. Always show the steps and label ‘bpm’ (beats per minute).
计算一名12岁儿童的最大心率时，220 – 12 = 208 bpm。如果要求计算最大心率的60%，学生有时会算错或漏写单位。务必展示计算步骤并标注“bpm”（次/分钟）。
8. Safety Principles and Injury Prevention | 安全原则与损伤预防
Safety in PE is tested through risk assessment, correct use of equipment, rules of activities and appropriate clothing. Questions often give a scenario and ask how to prevent injury.
体育课中的安全通过风险评估、正确使用器械、活动规则及合适的着装来考查。题目通常给出一个情景，要求回答如何预防受伤。
A frequent error is giving vague answers like “be careful” or “play safely”. Examiners expect specific precautions. For a gymnastics lesson, you should mention: mats must be placed under apparatus, jewellery must be removed, long hair tied back, a spotter should support the performer, and a warm‑up must be completed. Generic statements do not demonstrate understanding. Also, students sometimes confuse ‘prevention’ and ‘treatment’. If asked how to avoid blisters, the correct answer is “wear correctly fitting footwear and keep feet dry”, not “apply a plaster”.
一个常见的错误是给出“要小心”或“安全运动”这样含糊的答案。考官期望看到具体的预防措施。比如在一堂体操课上，你应提到：必须在器械下方铺设垫子、摘除首饰、扎起长发、安排保护者辅助完成动作、完成热身等。笼统的说法不能展现理解。此外，学生有时会混淆“预防”和“治疗”。如果问如何避免起水泡，正确答案是“穿合脚的鞋并保持足部干燥”，而不是“贴创可贴”。
The acronym rules: Rules, Understand, Listen, Equipment, Safety – can help, but knowing the practical application for specific sports is what scores marks.
可以借助一些记忆规则，但针对具体运动的实际应用才是得分关键。
9. Nutrition and Hydration for Young Athletes | 青少年运动员的营养与水分
The focus is on macronutrients (carbohydrates, proteins, fats) and their roles, plus the importance of hydration. Carbohydrates provide energy, protein aids muscle repair and growth, and fats supply long‑term energy and insulation.
重点是宏量营养素（碳水化合物、蛋白质、脂肪）及其作用，以及补水的重要性。碳水化合物提供能量，蛋白质有助于肌肉修复和生长，脂肪则提供长期能量和保温。
Students often underestimate the significance of timing and proportion. They might think a large protein meal right before running is ideal, but protein is slow to digest and can cause stomach discomfort. Carbohydrates should be the main fuel before exercise. Another error is confusing dehydration and its effects. A water loss of just 2% of body weight can impair performance, causing slower reactions, poor concentration and cramps. Many students only link dehydration to thirst, forgetting cognitive and physical impacts.
学生常低估摄入时机和比例的重要性。他们可能认为跑步前吃一顿高蛋白大餐是最佳选择，但蛋白质消化较慢，可能引起胃部不适。运动前应以碳水化合物为主要燃料。另一个错误是混淆脱水的概念及其影响。仅仅减轻体重2%的水分流失就会损害运动表现，导致反应变慢、注意力下降和抽筋。许多学生只把脱水和口渴联系起来，忘记了对认知和身体的影响。
Be able to give simple examples of healthy meals for a competition day, such as a pasta‑based lunch several hours before, and a banana 30 minutes before for quick energy. Avoid junk food classifications!
需要能够为比赛日给出简单的健康膳食建议，例如赛前几小时吃意大利面为主的午餐，赛前30分钟吃一根香蕉快速供能。避免把垃圾食品归类为运动营养！
10. Basic Motor Skills Classification | 基本运动技能分类
Motor skills are classified into discrete, serial and continuous skills on a continuum. A discrete skill has a clear beginning and end (e.g. a penalty kick). A serial skill links several discrete skills together (e.g. a gymnastics floor routine). A continuous skill has no obvious start or finish (e.g. swimming).
运动技能在连续体上被分为分立技能、序列技能和连续技能。分立技能有明确的开始和结束（例如点球）。序列技能将多个分立技能串联在一起（例如体操自由操）。连续技能没有明显的起点和终点（例如游泳）。
The biggest misconception is that a sequence of movements automatically makes something a serial skill. Students often label a sprint start as serial because runners use a set, ‘bang’ and drive phase. However, a sprint race is primarily a continuous skill once the race begins; the set start itself is a discrete skill. Also, classifying a skill can depend on the context: a single pass in netball is discrete, but a keep‑‑up drill could be seen as serial or continuous. Exam questions usually pick clear scenarios, so focus on the definitions.
最大的误解是，只要有一系列动作就一定属于序列技能。学生常将短跑起跑归类为序列技能，因为运动员要经过“各就位”、“枪响”和驱动阶段。但短跑比赛一旦开始，主要是一项连续技能；而预备起跑本身是分立技能。另外，技能分类有时取决于情境：无板篮球中的单独一次传球是分立技能，而颠球练习可被视作序列或连续技能。考题通常选取清晰的情境，所以要专注于定义。
Use the table approach to compare skill types against environmental stability (open/closed skills) if covered. For Year 7, discrete‑serial‑continuous is the high‑frequency demand.
如果课程涵盖了开放/闭锁技能，可以用表格来对比不同的技能类型与环境稳定性。对 Year 7 而言，分立‑序列‑连续是高频要求。
11. Introduction to the FITT Principle | FITT 原则入门
FITT stands for Frequency, Intensity, Time and Type – the key variables used to design a safe and effective exercise programme. Year 7 students must be able to define each and apply them to improve a specific fitness component.
FITT 代表频率、强度、时间和类型——这是设计安全有效锻炼计划的四个关键变量。Year 7 学生需要能够定义每一变量，并将其应用到提升特定体适能要素的计划中。
Common mistakes include applying generic numbers without linking to the goal. For improving cardiovascular endurance, frequency might be 3–5 times per week, intensity 60–80% of MHR, time 20–30 minutes, type jogging or cycling. But for muscular strength, intensity is heavy resistance and low repetitions. Students often copy the same FITT values for all components. Also, they confuse frequency (how often) with time (how long per session). A question might ask “Give an example of how you would increase time in your training plan” – simply writing “run longer” without linking to FITT definitions can lose clarity.
常见的错误包括套用通用数字，却没有与目标联系起来。若要改善心血管耐力，频率可以是每周3‑5次，强度为最大心率的60–80%，时间20‑30分钟，类型为慢跑或骑车。但对于肌肉力量，强度应该是大阻力、低重复次数。学生往往给所有要素套用相同的 FITT 数值。此外，他们会混淆频率（多久一次）和时间（每次多长）。题目可能问“举例说明你将如何在训练计划中增加时间”，只写“跑得更久”而不结合 FITT 的定义，会显得不够清晰。
Progression and overload are linked ideas. If the body adapts, you must increase the FITT variables to keep improving. A simple answer “lift a heavier weight” demonstrates type, but also intensity. Being precise wins marks.
渐进和超负荷是相关联的概念。如果身体适应了，就需要加大 FITT 变量才能继续进步。一个简单的回答“举起更重的重量”既体现出类型，也体现了强度。回答越精确，得分越高。
