在 Year 8 CIE 体育课程中，掌握特定词汇与掌握运动技能本身同样关键。许多学生觉得术语有难度，因为它融合了科学语言与实际的运动情境。本指南分解了你将遇到的核心术语，提供清晰的定义和记忆辅助，帮助你在课堂、作业和评估中快速回忆。把这看作是你通往体育理论成功的个人词典。
1. Bones and Skeletal Functions | 骨骼及其功能
The human skeleton provides more than just a framework. It has four primary functions: support, protection, movement, and blood cell production. Key bones to remember include the cranium, clavicle, scapula, humerus, radius, ulna, pelvis, femur, tibia, and fibula.
人体骨骼提供的不仅仅是一个框架。它有四个主要功能：支撑、保护、运动和血细胞生成。需要记住的关键骨骼包括颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、骨盆、股骨、胫骨和腓骨。
A popular mnemonic for the vertebral column from top to bottom is 'Canned Tuna Lamb Sausages Can't Compare': Cervical, Thoracic, Lumbar, Sacrum, Coccyx. The femur is the longest bone, while the stapes in the ear is the smallest.
从上到下记忆脊柱的一个流行助记法是"颈椎、胸椎、腰椎、骶骨、尾骨"取其首字。股骨是最长的骨骼，而耳朵中的镫骨是最小的。
2. Muscles and Movement Pairs | 肌肉与运动配对
Muscles work in antagonistic pairs, meaning one contracts while the other relaxes. The muscle contracting is the agonist (prime mover), and the relaxing muscle is the antagonist. For example, during a bicep curl, the biceps brachii is the agonist and the triceps brachii is the antagonist.
肌肉以拮抗对的形式工作，即一块肌肉收缩时，另一块放松。收缩的肌肉是主动肌（原动肌），放松的肌肉是指抗肌。例如，在肱二头肌弯举中，肱二头肌是主动肌，肱三头肌是指抗肌。
- Flexion: decreasing the angle at a joint (bending the elbow). | 屈曲：减小关节角度（弯曲肘部）。
- Extension: increasing the angle at a joint (straightening the knee). | 伸展：增大关节角度（伸直膝盖）。
- Abduction: moving a limb away from the body's midline. | 外展：将肢体远离身体中线。
- Adduction: moving a limb toward the body's midline. | 内收：将肢体靠向身体中线。
- Rotation: movement around a central axis (turning the head). | 旋转：围绕中心轴的运动（转动头部）。
To remember the hamstrings group, think 'Semi-s': semimembranosus, semitendinosus, and biceps femoris. These muscles flex the knee and extend the hip.
要记住腘绳肌群，想想"半"字开头的肌肉：半膜肌、半腱肌和股二头肌。这些肌肉负责屈膝和伸髋。
3. Lever Systems in Action | 杠杆系统在运动中的应用
A lever system consists of a rigid bar (bone), a pivot (joint), a load (weight/resistance), and an effort (muscle force). In PE, we classify levers as first, second, or third class depending on the position of the fulcrum (F), load (L), and effort (E).
杠杆系统由刚性杆（骨骼）、支点（关节）、负荷（重量/阻力）和力（肌肉力量）组成。在体育中，我们根据支点(F)、负荷(L)和力(E)的位置将杠杆分为一级、二级或三级。
| Lever Class | 杠杆类别 | Arrangement | 排列顺序 | Sporting Example | 运动实例 |
|---|---|---|
| First Class | 一级 | F, L, E or F, E, L | Nodding the head (neck extension) | 点头（颈部伸展） |
| Second Class | 二级 | F, L, E | Standing on tiptoes (calf raise) | 踮脚站立（提踵） |
| Third Class | 三级 | F, E, L | Bicep curl | 肱二头肌弯举 |
Most movements in the human body use third-class levers because they allow a wide range of motion and speed, even though they require more effort. Remember: 'FLE' for second class means the load is in the middle.
人体内大多数运动使用三级杠杆，因为它们允许较大的活动范围和速度，尽管需要更多的力。记住：二级杠杆的'FLE'意思是负荷在中间。
4. Planes of Movement and Axes | 运动平面与轴
To describe how a body moves through space, we use three planes (imaginary flat surfaces) and three axes (imaginary lines). The plane is the surface through which movement occurs, and the axis is the line around which the body rotates.
为了描述身体如何在空间中移动，我们使用三个平面（假想的平面）和三个轴（假想的线）。平面是运动发生的表面，轴是身体围绕其旋转的线。
- Sagittal plane divides the body into left and right. Movements: flexion, extension. Axis: frontal. | 矢状面将身体分为左右。动作：屈曲、伸展。轴：额状轴。
- Frontal plane divides the body into front and back. Movements: abduction, adduction. Axis: sagittal. | 额状面将身体分为前后。动作：外展、内收。轴：矢状轴。
- Transverse plane divides the body into top and bottom. Movements: rotation. Axis: vertical. | 横断面将身体分为上下。动作：旋转。轴：垂直轴。
A somersault happens in the sagittal plane around the frontal axis. A cartwheel happens in the frontal plane around the sagittal axis. A pirouette in dance happens in the transverse plane around the vertical axis.
前空翻是在矢状面内围绕额状轴发生的。侧手翻是在额状面内围绕矢状轴发生的。舞蹈中的单脚尖旋转是在横断面内围绕垂直轴发生的。
5. The Circulatory and Respiratory Systems | 循环系统与呼吸系统
The circulatory system includes the heart, blood vessels (arteries, veins, capillaries), and blood. Its main role is transporting oxygen, nutrients, and hormones while removing waste products like carbon dioxide. Key term: Heart Rate (HR) is the number of times the heart beats per minute (bpm).
循环系统包括心脏、血管（动脉、静脉、毛细血管）和血液。其主要作用是将氧气、营养物质和激素输送到全身，同时清除二氧化碳等废物。关键术语：心率(HR)是心脏每分钟跳动的次数(bpm)。
The respiratory system brings oxygen into the body and expels carbon dioxide. Tidal volume is the amount of air inhaled or exhaled in one normal breath. Vital capacity is the maximum amount of air you can forcibly exhale after a maximum inhalation.
呼吸系统将氧气带入体内并排出二氧化碳。潮气量是一次正常呼吸中吸入或呼出的空气量。肺活量是最大吸气后能强行呼出的最大空气量。
During exercise, breathing rate increases to take in more oxygen for the working muscles. This exchange of gases happens at the alveoli, tiny air sacs in the lungs surrounded by capillaries.
运动期间，呼吸频率加快，以便为工作的肌肉吸入更多氧气。这种气体交换发生在肺泡中，肺泡是肺部被毛细血管包围的微小气囊。
6. Components of Fitness: Health-Related | 健康相关体能要素
Health-related fitness components directly affect your overall well-being and ability to perform daily tasks without undue fatigue. There are five main areas, often remembered by the acronym 'BCFMS'.
健康相关体能要素直接影响你的整体健康和在不过度疲劳的情况下执行日常任务的能力。主要有五个方面，常用缩略词'BCFMS'来记忆。
- Body Composition: the ratio of fat mass to lean mass (muscle, bone, organs) in the body. | 身体成分：体内脂肪重量与去脂体重（肌肉、骨骼、器官）的比率。
- Cardiovascular Endurance: the ability of the heart and lungs to supply oxygen to working muscles over a sustained period. | 心血管耐力：心脏和肺部在持续时间内为工作肌肉供氧的能力。
- Flexibility: the range of motion around a joint. | 柔韧性：关节的活动范围。
- Muscular Endurance: the ability of a muscle or muscle group to perform repeated contractions without fatigue. | 肌耐力：一束肌肉或肌群在无疲劳状态下反复收缩的能力。
- Muscular Strength: the maximum force a muscle can exert in a single contraction. | 肌力：肌肉在单次收缩中能施加的最大力量。
Cardiovascular endurance is tested by the multi-stage fitness test (bleep test), while strength is often measured by the handgrip dynamometer test.
心血管耐力通过多阶段体能测试（哔哔声测试）来测量，而力量通常通过握力计测试来测量。
7. Components of Fitness: Skill-Related | 技能相关体能要素
Skill-related fitness components are more about performance in sports and specific activities. They help an athlete learn and execute complex skills. The six components, remembered by 'CAP RAB', are crucial for game play.
技能相关体能要素更侧重于运动表现和特定活动。它们帮助运动员学习和执行复杂技能。六大要素，用'CAP RAB'来记，对比赛至关重要。
- Coordination: the ability to use two or more body parts together smoothly and efficiently. | 协调性：流畅高效地同时运用两个或多个身体部位的能力。
- Agility: the ability to change direction quickly and control the body's position. | 敏捷性：快速改变方向并控制身体位置的能力。
- Power: the combination of strength and speed (strength x speed). | 爆发力：力量与速度的结合（力 × 速度）。
- Reaction Time: the time taken to respond to a stimulus. | 反应时间：对刺激做出反应所需的时间。
- Agility (again): some models use 'Speed' here to complete the acronym properly, but Agility is often covered. | 敏捷性（再次）：有些模型用"速度"来完整拼读缩略词，但敏捷性常被涵盖。
- Balance: the ability to maintain the body's centre of mass over its base of support. | 平衡：将身体重心保持在支撑面内的能力。
A gymnast on a beam needs exceptional balance; a sprinter leaving the blocks relies on reaction time and power.
平衡木上的体操运动员需要极佳的平衡能力；起跑器上的短跑运动员依赖反应时间和爆发力。
8. Principles of Training (SPORT & FITT) | 训练原则 (SPORT 与 FITT)
To improve fitness safely and effectively, training must follow specific principles. The SPORT principles are Specificity, Progression, Overload, Reversibility, and Tedium. Overload itself is governed by the FITT principle: Frequency, Intensity, Time, and Type.
为了安全有效地提升体能，训练必须遵循特定原则。SPORT原则包括针对性(Specificity)、渐进性(Progression)、超负荷(Overload)、可逆性(Reversibility)和枯燥性(Tedium)。超负荷本身又由FITT原则控制：频率(Frequency)、强度(Intensity)、时间(Time)和类型(Type)。
Specificity means training must be relevant to the sport or goal. A marathon runner focuses on cardiovascular endurance, not weightlifting. Progression means gradually increasing the difficulty to avoid injury and plateauing.
针对性指训练必须与运动项目或目标相关。马拉松跑者注重心血管耐力，而非举重。渐进性指逐步增加难度以避免受伤和平台期。
Reversibility is often summarised as 'use it or lose it.' Fitness gains are lost when you stop training. Tedium means variety is needed to prevent boredom and maintain motivation.
可逆性常被概括为"用进废退"。停止训练时，已获得的体能水平会下降。枯燥性指需要多样化训练以防止厌烦并保持动力。
9. Methods of Training | 训练方法
Different training methods target different fitness components. Continuous training involves aerobic activity at a steady pace for at least 20 minutes without rest, good for cardiovascular endurance. Interval training alternates between high-intensity work periods and rest or low-intensity recovery periods.
不同的训练方法针对不同的体能要素。持续训练法指以稳定配速进行至少20分钟的有氧活动并无休息，有利于心血管耐力。间歇训练法在高强度工作时段与休息或低强度恢复时段之间交替进行。
- Fartlek training: 'speed play' where the athlete varies pace and terrain spontaneously during a continuous run. | 法特莱克训练法：在连续跑步过程中运动员自发改变速度和地形的"速度游戏"。
- Circuit training: a series of exercises (stations) completed in order, targeting different muscle groups or fitness components. | 循环训练法：按顺序完成一系列练习（站点），针对不同肌群或体能要素。
- Plyometric training: explosive movements like bounding, hopping, and jumping to develop power. | 增强式训练法：如跨步、单脚跳和跳跃等爆发性动作，旨在提升爆发力。
- Weight/resistance training: using free weights, machines, or body weight to improve muscular strength and endurance. | 重量/抗阻训练法：通过自由重量、器械或自身体重来提升肌力和肌耐力。
Interval training can be adjusted for intensity using work-to-relief ratios, for example, a 1:2 ratio means the rest period is twice as long as the work period.
间歇训练可以通过运动-休息比率来调整强度，例如，1:2的比率意味着休息时间是运动时间的两倍。
10. Energy Systems Basics | 能量系统基础
Your muscles need energy in the form of Adenosine Triphosphate (ATP) to contract. There are two main ways to produce ATP without oxygen (anaerobic) and one with oxygen (aerobic).
你的肌肉需要三磷酸腺苷(ATP)形式的能量来收缩。主要有两种无需氧气产生ATP的方式（无氧）和一种需要氧气的方式（有氧）。
- Anaerobic (ATP-PC system): provides immediate energy for up to 10 seconds of maximal effort (e.g., 100m sprint, power clean). Uses phosphocreatine stores. | 无氧（ATP-PC系统）：为最高强度运动提供最多10秒的即时能量（如百米冲刺、高翻）。利用磷酸肌酸储备。
- Anaerobic (Lactic acid system): provides energy for high-intensity activity lasting 60-90 seconds (e.g., 400m run). Produces lactic acid as a by-product. | 无氧（乳酸系统）：为持续60-90秒的高强度活动提供能量（如400米跑）。产生乳酸作为副产品。
- Aerobic system: provides energy for low to moderate intensity activity lasting longer than 2 minutes. Uses oxygen to break down carbohydrates and fats. | 有氧系统：为持续2分钟以上的中低强度活动提供能量。利用氧气分解碳水化合物和脂肪。
A simple tip: 'P for Power, L for Longer efforts, A for Anything over two minutes'. The onset of blood lactate accumulation (OBLA) occurs around 4 mmol/L and causes fatigue.
一个简单的提示："P代表爆发力，L代表较长时间的努力，A代表任何超过两分钟的活动"。血乳酸积累起点约为4毫摩尔/升并导致疲劳。
11. Skill Classification and Information Processing | 技能分类与信息处理
Skills are classified along different continua (endless scales) to help coaches design effective practice. The main continua are open-closed, gross-fine, simple-complex, and self-paced-externally paced.
技能沿不同的连续体（无界尺度）进行分类，以帮助教练设计有效的训练。主要连续体是开放-闭锁、粗大-精细、简单-复杂和自定节奏-外部节奏。
An open skill is performed in an unpredictable environment where the performer must adapt (e.g., a tackle in rugby). A closed skill is performed in a stable, predictable environment (e.g., a free throw in basketball).
开放型技能是在不可预测的环境中执行的，执行者必须适应（如橄榄球中的擒抱）。闭锁型技能是在稳定、可预测的环境中执行的（如篮球中的罚球）。
aking (brain processes options) → Output (muscles produce movement) → Feedback (information about the result).
信息处理解释了我们如何做出决策。基本模型为：输入（感官接收环境信息）→ 决策（大脑处理选项）→ 输出（肌肉产生运动）→ 反馈（关于结果的信息）。
12. Nutrition, Hydration, and Goal Setting | 营养、水合作用与目标设定
A balanced diet provides the fuel for performance and recovery. Macronutrients: Carbohydrates are the body's preferred energy source (pasta, rice). Proteins are for muscle repair and growth (chicken, beans). Fats provide slow-release energy and insulation. Micronutrients are vitamins and minerals needed in small amounts.
均衡的饮食为运动表现和恢复提供燃料。常量营养素：碳水化合物是身体首选的能量来源（意面、米饭）。蛋白质用于肌肉修复和生长（鸡肉、豆类）。脂肪提供缓慢释放的能量和绝缘。微量营养素是少量需要的维生素和矿物质。
Hydration is critical because even small fluid losses (2% of body weight) can impair performance. Water regulates body temperature and transports nutrients. Isotonic sports drinks typically contain 6-8% carbohydrate and replace fluids and electrolytes quickly.
水合作用至关重要，因为即使是少量体液流失（体重的2%）也会损害运动表现。水分参与调节体温并运输营养物质。等渗运动饮料通常含有6-8%的碳水化合物，能快速补充液体和电解质。
SMART goal setting gives direction to training: Specific, Measurable, Achievable, Realistic, Time-bound. Instead of 'get fitter,' a SMART goal is 'reduce my 1500m time by 30 seconds within 8 weeks.'
SMART目标设定为训练提供方向：S具体的、M可衡量的、A可实现的、R现实的、T有时间限制的。与其说"变得更强健"，一个SMART目标是"在8周内将1500米成绩提高30秒"。
