1. The Skeletal System: Bones You Must Know | 骨骼系统：必须掌握的骨骼
In Year 7 OCR PE, you are expected to name and locate the major bones of the body. The key bones include the skull, clavicle, scapula, humerus, radius, ulna, ribs, sternum, vertebrae, pelvis, femur, patella, tibia and fibula. You may also be asked about the five main functions of the skeleton: support, protection, movement, blood cell production and mineral storage.
在七年级OCR体育中，你需要说出并定位人体的主要骨骼。关键骨骼包括颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、肋骨、胸骨、椎骨、骨盆、股骨、髌骨、胫骨和腓骨。你可能还会被问到骨骼的五大功能：支持、保护、运动、血细胞生成和矿物质储存。
A very common mistake is confusing the bones of the lower arm and lower leg. Students often mix up the radius and ulna, or the tibia and fibula. Remember: the radius is on the thumb side and the ulna is on the little-finger side of the forearm. In the lower leg, the tibia is the larger, weight-bearing bone, while the fibula is thinner and sits on the outside.
一个非常常见的错误是混淆前臂和小腿的骨骼。学生经常搞混桡骨和尺骨，或是胫骨和腓骨。请记住：桡骨位于大拇指侧，尺骨位于小指侧。在小腿中，胫骨是较大且承重的骨骼，而腓骨较细，位于外侧。
Another pitfall occurs when labelling diagrams. Do not simply write ‘bone’ — always provide the specific anatomical name. Also, note the spelling: ‘femur’ not ‘femur’, ‘clavicle’ not ‘clavical’. Marks are often lost for missing a letter.
另一个易错点出现在图示标注中。不要只写“骨头”——务必给出具体的解剖名称。同时要注意拼写：是“femur”而不是“femmer”，是“clavicle”而不是“clavical”。常因漏写字母而丢分。
The functions of the skeleton are frequently tested with examples. For instance, protection: the ribcage protects the heart and lungs. Support: the vertebrae support the head and upper body. Be ready to match each function to a correct bone or set of bones.
骨骼功能常结合例子考查。例如，保护：肋骨保护心脏和肺。支持：椎骨支撑头部和上身。要准备好将每种功能与正确的骨头或骨组匹配起来。
2. The Muscular System: Major Muscles and Movements | 肌肉系统：主要肌肉与动作
The major muscles you must know for Year 7 include biceps, triceps, deltoid, pectorals, abdominals, quadriceps, hamstrings, gastrocnemius and gluteals. You need to understand that muscles work in antagonistic pairs to create movement at joints — when one muscle contracts (agonist), the other relaxes (antagonist).
七年级需要认识的主要肌肉包括肱二头肌、肱三头肌、三角肌、胸大肌、腹肌、股四头肌、腘绳肌、腓肠肌和臀大肌。你需要明白肌肉以拮抗对的形式协同工作，当一块肌肉收缩（主动肌）时，另一块则放松（拮抗肌），从而在关节处产生动作。
The most common error is confusing the quadriceps and hamstrings. The quadriceps are on the front of the thigh and extend the knee; the hamstrings are on the back of the thigh and flex the knee. Many students also wrongly believe that the biceps and triceps are in the leg — they are in the upper arm.
最常见的错误是混淆股四头肌和腘绳肌。股四头肌位于大腿前侧，负责伸膝；腘绳肌位于大腿后侧，负责屈膝。许多学生还错误地认为肱二头肌和肱三头肌在腿部——其实它们在上臂。
When asked to describe the movement, avoid vague terms. Use correct movement vocabulary such as flexion, extension, abduction, adduction where appropriate. For example, during a bicep curl, the biceps brachii contracts and the triceps relaxes to cause flexion at the elbow.
当被要求描述动作时，避免模糊用语。在合适的情况下，使用正确的运动词汇，如屈曲、伸展、外展、内收。例如，做肱二头肌弯举时，肱二头肌收缩、肱三头肌放松，使肘部发生屈曲。
Table 1 gives a quick reference to the major muscles and their primary actions.
表1提供了主要肌肉及其主要动作的快速参考。
| Muscle (English) | 中文名称 | Main Action |
|---|---|---|
| Biceps | 肱二头肌 | Flexes the elbow |
| Triceps | 肱三头肌 | Extends the elbow |
| Quadriceps | 股四头肌 | Extends the knee |
| Hamstrings | 腘绳肌 | Flexes the knee |
| Gastrocnemius | 腓肠肌 | Plantar flexes the ankle (points toes) |
3. Components of Fitness: Health-Related vs. Skill-Related | 体能组成：健康相关与技能相关
You must confidently separate the health-related components (cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition) from the skill-related components (agility, balance, coordination, power, reaction time, speed). Exam questions often ask you to identify which component is most important for a particular sport or to define a term.
你必须能信手区分健康相关的体能组成（心血管耐力、肌肉力量、肌肉耐力、柔韧性、身体成分）和技能相关的体能组成（敏捷性、平衡、协调、功率、反应时间、速度）。试题经常要求你识别哪项体能对特定运动最重要，或定义某个术语。
A classic mistake is classifying power as health-related. In OCR specifications for this age, power is skill-related because it combines strength and speed, and is vital for explosive actions like jumping or throwing. Likewise, many students confuse muscular endurance with cardiovascular endurance. Muscular endurance is the ability of a muscle to keep contracting without fatigue; cardiovascular endurance is the ability of the heart and lungs to supply oxygen to working muscles over time.
一个经典错误是把功率归为健康相关。在OCR此阶段的大纲中，功率属于技能相关体能，因为它结合了力量和速度，对于跳跃或投掷等爆发性动作至关重要。同样，许多学生混淆肌肉耐力与心血管耐力。肌肉耐力是一块肌肉持续收缩而不疲劳的能力；心血管耐力是心脏和肺部长时间为工作肌肉供氧的能力。
When linking components to sports, be specific. For example, a gymnast needs excellent balance and flexibility, while a 1500-metre runner relies on cardiovascular endurance. Do not write ‘fitness’ as a catch-all answer.
在将体能组成与运动相联系时，要具体。比如，体操运动员需要出色的平衡和柔韧性，而1500米跑者则依赖心血管耐力。不要用“fitness”作为笼统答案。
4. Principles of Training: Applying FITT | 训练原则：FITT原则的应用
The FITT acronym — Frequency, Intensity, Time, Type — is a high-frequency topic. You must be able to explain how to apply each element to improve a specific component of fitness. For instance, to improve cardiovascular endurance, a suitable plan could be: Frequency – 3 times per week; Intensity – 60–80% of maximum heart rate; Time – 30 minutes; Type – continuous running or cycling.
FITT首字母缩略词（频率、强度、时间、类型）是高频考点。你必须能够解释如何应用每个要素来提升某一特定的体能组成。例如，为提高心血管耐力，一个合适的计划可以是：频率——每周3次；强度——最大心率的60–80%；时间——30分钟；类型——持续性跑步或骑车。
Common mistakes include mixing up intensity and time, or ignoring the type of exercise. Students sometimes write ‘Intensity: 30 minutes’. Always match the unit correctly. Intensity is often expressed as a percentage of max HR or perceived exertion; time is measured in minutes or hours.
常见错误包括混淆强度和时间的定义，或者忽略了运动类型。学生有时会写“强度：30分钟”。务必正确匹配单位。强度常以最大心率百分比或自觉费力程度表示；时间则用分钟或小时来衡量。
Another pitfall is failing to link the training programme to the intended fitness component. If asked to improve flexibility, your FITT plan must involve stretching exercises as the Type, not running. Think about specificity.
另一个误区是未能将训练计划与目标体能组成联系起来。如果被问到如何提高柔韧性，你的FITT计划中必须包含伸展练习作为类型，而不是跑步。需考虑专项化原则。
5. Heart Rate, Maximum Heart Rate, and Recovery | 心率、最大心率与恢复
You need to know how to estimate maximum heart rate (MHR) and interpret recovery heart rate. The simple formula used in Year 7 is:
你需要知道如何估算最大心率（MHR）并解释恢复心率。七年级使用的简单公式为：
MHR = 220 – age
A typical mistake is subtracting the age from 200 or using the wrong order of operations. Double-check your arithmetic — even a small error loses marks. Also note that heart rate is measured in beats per minute (bpm).
一个典型错误是从200中减去年龄，或者运算顺序出错。仔细检查你的算术——即使是一个小错误也会丢分。还要注意心率以每分钟搏动次数（bpm）来测量。
Recovery heart rate is the speed at which your heart rate returns to normal after exercise. A faster recovery indicates a higher level of cardiovascular fitness. Exam questions often give a set of data and ask you to compare recovery rates or explain what they suggest about fitness levels.
恢复心率是指运动结束后心率恢复到正常水平的速度。恢复越快，表明心血管健康水平越高。考题常给出一组数据，要求你比较恢复心率，或解释这些数据说明了什么样的健康水平。
When calculating target training zones, remember to apply the percentages after finding MHR, not to the raw 220 value. For example, 60% of (220 – 12) is not 60% of 220. Write out the working step by step to avoid errors.
计算目标训练区间时，记住是求得最大心率之后再算百分比，而不是直接对220运用百分比。例如，60%×(220–12) ≠ 60%×220。请逐步写出计算过程以避免错误。
6. Warm-Up and Cool-Down: The Three Phases | 热身与放松：三个阶段
A structured warm-up has three phases: a pulse raiser (e.g. light jogging), stretching (especially dynamic stretches), and a skill-related activity (e.g. short sprints or ball drills). The cool-down typically involves gentle exercise followed by static stretching. Both are crucial for preventing injury and aiding recovery.
一次结构完整的热身包含三个阶段：脉搏提升（如慢跑）、拉伸（尤其是动态拉伸）和与技能相关的活动（如短距离冲刺或球类练习）。放松通常包括轻微运动之后进行静态拉伸。两者对于预防损伤和促进恢复至关重要。
The most frequent mistake is missing out the skill-related phase in the warm-up, or stating that static stretching should be done at the very beginning of a warm-up. Dynamic stretches are now recommended during warm-ups to prepare the muscles for the specific movements they will perform.
最常见的错误是遗漏热身中的技能相关阶段，或者认为热身一开始就应该做静态拉伸。现在推荐在热身中进行动态拉伸，以使肌肉为即将进行的专项动作做好准备。
In the cool-down, students often forget to mention that gradual cooling helps remove waste products like lactic acid and reduces the chance of dizziness or fainting. Always explain why each stage is included — not just what you do.
在放松阶段，学生们常常忘记提到逐渐降温有助于清除乳酸等代谢废物，并减少头晕或昏厥的可能。始终要解释每个阶段为什么存在——而不仅仅是描述你做什么。
7. Nutrition, Energy, and Hydration | 营养、能量与补水
You need to know the main macronutrients and their roles: carbohydrates provide the body’s main energy source, fats provide energy for low-intensity activity and also insulate and protect organs, and protein is essential for growth and repair of tissues. Hydration is just as important — even slight dehydration can impair physical and mental performance.
你需要了解主要宏量营养素及其作用：碳水化合物提供身体的主要能量来源，脂肪为低强度活动提供能量并保温、保护器官，蛋白质对组织生长和修复至关重要。补水同样重要——哪怕轻微脱水也会损害身体和心理表现。
A widespread misconception is that protein is the body’s primary fuel. In reality, carbohydrates are the preferred fuel, especially during high-intensity exercise. Only when carbohydrate stores are depleted does protein significantly contribute to energy needs.
一个普遍的误解是蛋白质是身体的首要燃料。实际上，碳水化合物是首选燃料，尤其是在高强度运动期间。只有当碳水化合物储备耗尽时，蛋白质才会显著贡献能量。
Another error involves oversimplifying. Avoid simply writing ‘carbs give you energy’ — add context, such as ‘complex carbohydrates like pasta release energy slowly and are ideal before a long-distance event.’ Be prepared to suggest appropriate pre- and post-event meals.
另一个错误是过度简化。避免只写“碳水化合物给你能量”——要添加语境，例如“像意大利面这样的复合碳水化合物释放能量较慢，适合长距离比赛前食用”。要准备好建议合适的赛前和赛后膳食。
Use Table 2 to quickly recall the functions and examples of each nutrient.
利用表2快速回顾每种营养素的功能和实例。
| Nutrient | Main Function | Example Foods |
|---|---|---|
| Carbohydrates | Main energy source | Pasta, rice, bread |
| Fats | Long-term energy, insulation | Avocado, cheese, oils |
| Protein | Growth and repair | Chicken, eggs, beans |
8. Skill Acquisition and Practice Types | 技能习得与练习类型
OCR Year 7 will often ask you to match a skill to an appropriate type of practice. Fixed (repetition) practices are best for closed skills performed in a stable environment (e.g. a free throw in basketball), while variable practices are suited to open skills where conditions change (e.g. a pass in a football match).
OCR七年级经常要求你为特定技能匹配合适的练习类型。固定（重复）练习最适合在稳定环境下执行的闭锁性技能（如篮球罚篮），而变化练习则适用于条件多变的开放性技能（如足球比赛中的传球）。
Students frequently confuse massed and distributed practice. Massed practice involves continuous work with little or no rest — good for simple skills or when time is short. Distributed practice includes rest intervals and is more effective for learning complex skills or when fatigue sets in. Always justify your choice.
学生经常混淆集中练习与分散练习。集中练习是连续工作，休息很少或没有——适于简单技能或时间紧张时。分散练习包含休息间隔，对学习复杂技能或疲劳时更有效。始终要说明你的选择理由。
Feedback is another key topic. Intrinsic feedback comes from your own senses (how the movement felt), while extrinsic feedback comes from outside sources (coach, video, stopwatch). Beginners rely more on extrinsic feedback; skilled performers use intrinsic feedback. Do not confuse the two.
反馈是另一个关键主题。内在反馈来自自身感官（动作做起来感觉如何），外在反馈来自外部来源（教练、视频、秒表）。初学者更依赖外在反馈；熟练者则使用内在反馈。不要把两者混淆。
9. Common Exam Mistakes and How to Avoid Them | 常见考试错误与避免方法
Many marks are lost through poor exam technique rather than lack of knowledge. Top mistakes include: not reading the question carefully (e.g. naming a muscle when a bone is asked), missing command words like ‘describe’, ‘explain’, or ‘compare’, and failing to provide sporting examples. Always underline key terms in the question.
许多丢分是由于考试技巧不佳，而非缺乏知识。最严重的错误包括：不仔细读题（比如要求举出骨骼却写了肌肉名称），忽略诸如“描述”“解释”“比较”之类的命令词，以及未能提供运动实例。始终在题目中划出关键词。
Spelling is often penalised in anatomy questions. Practise writing the names of all listed bones and muscles several times. Remember: ‘hamstrings’ has an ‘s’ at the end, and ‘quadriceps’ is already plural — never write ‘quadricep’.
拼写在解剖学问题中常被扣分。多次练习书写
