Each section is designed to reinforce essential vocabulary and concepts that will support both practical performance and written assessments.
Year 8 体育课程为学生理解运动与锻炼中身体的运作方式奠定基础。本复习指南涵盖 CIE 框架的核心主题，包括体能要素、骨骼与肌肉系统、能量途径、训练原则以及健康生活方式的重要性。每个部分旨在巩固关键术语和概念，帮助学生提升实操表现与书面考试能力。
1. Components of Fitness | 体能要素
Fitness is not a single quality but a combination of different components. Health-related fitness includes cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Skill-related fitness covers agility, balance, coordination, power, reaction time, and speed. Understanding each component helps athletes identify personal strengths and areas for improvement in their chosen sports.
体能不是单一素质，而是多种要素的组合。健康相关体能包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。技能相关体能涵盖敏捷性、平衡能力、协调性、爆发力、反应时间和速度。理解每项要素有助于运动员在所选运动中识别个人优势与改进方向。
- Cardiovascular endurance – the ability of the heart and lungs to supply oxygen during sustained activity.
- 心血管耐力 – 心脏和肺部在持续活动中供应氧气的能力。
- Agility – the capacity to change direction quickly while maintaining control.
- 敏捷性 – 在保持控制的同时快速改变方向的能力。
2. The Skeletal System | 骨骼系统
The human skeleton provides structure, protection, and movement. Bones act as levers, and joints allow different types of motion. Key bones in the CIE syllabus include the cranium, clavicle, sternum, ribs, humerus, radius, ulna, pelvis, femur, patella, tibia, and fibula. Learning the names and locations of these bones is fundamental for analysing movement and preventing injury.
人体骨骼提供结构支撑、保护与运动功能。骨骼充当杠杆，关节允许多种类型的运动。CIE 教学大纲中的关键骨骼包括颅骨、锁骨、胸骨、肋骨、肱骨、桡骨、尺骨、骨盆、股骨、髌骨、胫骨和腓骨。学习这些骨骼的名称与位置是分析运动与预防受伤的基础。
| Bone 骨骼 | Function 功能 |
|---|---|
| Femur 股骨 | Longest bone, supports body weight 最长骨，支撑体重 |
| Ribs 肋骨 | Protect heart and lungs 保护心脏与肺 |
3. Joints and Movement | 关节与运动
Joints are where two or more bones meet. Synovial joints, such as hinge and ball-and-socket joints, are freely movable and essential for sporting actions. Hinge joints (e.g., knee, elbow) allow flexion and extension. Ball-and-socket joints (e.g., shoulder, hip) permit flexion, extension, abduction, adduction, rotation, and circumduction. Recognising these movements helps in describing techniques like a basketball free throw or a sprinterʼs leg drive.
关节是两块或多块骨骼的连接处。滑膜关节（如铰链关节和球窝关节）可自由活动，对运动动作至关重要。铰链关节（如膝关节、肘关节）允许屈曲和伸展。球窝关节（如肩关节、髋关节）允许屈曲、伸展、外展、内收、旋转和环转。识别这些运动有助于描述篮球罚球或短跑运动员腿部发力等技术动作。
- Flexion – decreasing the angle at a joint, e.g., bending the elbow.
- 屈曲 – 减小关节角度，例如弯曲肘部。
- Abduction – moving a limb away from the body midline.
- 外展 – 将肢体移离身体中线。
4. The Muscular System | 肌肉系统
Muscles work by contracting and pulling on bones to create movement. Voluntary skeletal muscles operate in pairs: the agonist (prime mover) contracts while the antagonist relaxes. Key muscles include the deltoid, biceps, triceps, pectorals, abdominals, quadriceps, hamstrings, and gastrocnemius. Understanding muscle actions during specific exercises deepens awareness of technique and training effectiveness.
肌肉通过收缩并牵拉骨骼来产生运动。随意骨骼肌成对工作：主动肌（原动肌）收缩时，拮抗肌放松。主要肌肉包括三角肌、肱二头肌、肱三头肌、胸肌、腹肌、股四头肌、腘绳肌和腓肠肌。理解特定练习中的肌肉动作能加深对技术与训练效果的认识。
For a bicep curl: the biceps brachii acts as the agonist (shortens); the triceps brachii acts as the antagonist (lengthens). 在肱二头肌弯举中：肱二头肌为主动肌（缩短）；肱三头肌为拮抗肌（伸长）。
5. Energy Systems | 能量系统
Movement requires energy, which the body produces through different systems depending on intensity and duration. The aerobic system uses oxygen to break down carbohydrates and fats for sustained, moderate-intensity activity like jogging. The anaerobic system provides quick energy without oxygen for short, high-intensity bursts like sprinting. Year 8 students should grasp the basic difference between aerobic and anaerobic respiration and recognise examples from different sports.
运动需要能量，身体根据强度与持续时间通过不同系统产生能量。有氧系统利用氧气分解碳水化合物和脂肪，为慢跑等持续中等强度活动供能。无氧系统在无氧条件下快速供能，用于短跑等高强度爆发性运动。Year 8 学生应掌握有氧与无氧呼吸的基本区别，并能识别不同运动中的实例。
Aerobic equation (简单表达): Glucose + O₂ → Energy + CO₂ + H₂O
有氧供能 (简单表达): 葡萄糖 + 氧气 → 能量 + 二氧化碳 + 水
6. Principles of Training | 训练原则
Effective training follows the FITT principle: Frequency, Intensity, Time, and Type. Frequency is how often you train; intensity refers to how hard; time is the duration of each session; type is the specific exercise chosen. Additionally, the principles of overload, progression, and specificity ensure that the body continues to adapt and improve. Overload must be applied gradually – increasing weight, reps, or distance in small increments to avoid injury.
有效训练遵循 FITT 原则：频率（Frequency）、强度（Intensity）、时间（Time）和类型（Type）。频率指训练次数；强度指训练难度；时间指每次训练的时长；类型指所选的特定练习。此外，超负荷、渐进性与专项性原则确保身体持续适应与提升。超负荷应逐步施加——小幅度增加重量、次数或距离，避免受伤。
- Specificity – training must be relevant to the sport or goal.
- 专项性 – 训练必须与运动项目或目标相关。
- Progression – gradually increasing the challenge as fitness improves.
- 渐进性 – 随体能提升逐步增加挑战。
7. Health, Wellbeing, and Lifestyle | 健康、幸福感与生活方式
Health encompasses physical, mental, and social wellbeing, not merely the absence of disease. Regular exercise improves cardiovascular efficiency, strengthens muscles and bones, reduces stress, enhances mood, and promotes better sleep. A balanced lifestyle also requires adequate rest, proper nutrition, and positive social connections. Students are encouraged to reflect on their own activity levels and make small, sustainable changes toward a healthier routine.
健康涵盖身体、心理与社会幸福感，而不仅仅是没有疾病。规律锻炼能提高心血管效率、强健肌肉与骨骼、减轻压力、改善情绪并促进更佳睡眠。均衡的生活方式还需要充足的休息、合理的营养以及积极的社会联系。鼓励学生反思自身活动水平，并做出小而可持续的改变，迈向更健康的日常节奏。
8. Nutrition and Hydration | 营养与水分补充
Nutrition provides the fuel for physical performance. Macronutrients – carbohydrates, proteins, and fats – serve different roles: carbohydrates are the primary energy source; proteins aid muscle repair and growth; fats supply long-duration energy and support cell function. Micronutrients (vitamins and minerals) and water are equally vital. Dehydration impairs concentration, increases fatigue, and raises the risk of heat-related illness, so drinking water before, during, and after exercise is essential.
营养为身体表现提供燃料。宏量营养素——碳水化合物、蛋白质和脂肪——各司其职：碳水化合物是主要能量来源；蛋白质帮助肌肉修复与生长；脂肪提供长时间供能并支持细胞功能。微量营养素（维生素与矿物质）以及水分同样至关重要。脱水会损害专注力、加剧疲劳并升高热相关疾病的风险，因此运动前、中、后饮水不可或缺。
| Nutrient 营养素 | Role in Sport 在运动中的作用 |
|---|---|
| Carbohydrates 碳水化合物 | Immediate energy for working muscles 为工作肌肉即时供能 |
| Protein 蛋白质 | Repairs muscle tissue after exercise 修复运动后肌肉组织 |
9. Warm-up and Cool-down | 热身与整理活动
A thorough warm-up prepares the body for exercise and reduces injury risk. It should include pulse-raising activities, dynamic stretching, and sport-specific drills. Warming up increases heart rate, blood flow to muscles, joint mobility, and mental readiness. A cool-down gradually returns the body to its resting state; it typically involves light jogging followed by static stretching to aid recovery and reduce muscle stiffness.
充分的热身让身体为运动做好准备并降低受伤风险。热身应包括提升心率的活动、动态拉伸以及与运动专项相关的练习。热身能增加心率、肌肉血流、关节活动度和心理准备度。整理活动使身体逐步恢复至静息状态；通常包括轻微慢跑后接静态拉伸，以助恢复并减少肌肉僵硬。
10. Safety and Injury Prevention | 安全与伤害预防
Preventing injury is a shared responsibility between athletes, coaches, and officials. Common causes of injury include poor technique, inadequate warm-up, overtraining, and unsuitable equipment. Protective gear – helmets, shin pads, mouthguards – must be worn where required. Rules and fair play exist not only to uphold the spirit of sport but also to protect participants from harm. Recognising early signs of injury, such as persistent pain or swelling, and seeking prompt treatment prevents minor issues from becoming serious.
预防伤病是运动员、教练和裁判员的共同责任。受伤的常见原因包括技术不当、热身不足、过度训练以及装备不合适。防护装备——头盔、护胫、护齿——在需要时务必佩戴。规则与公平竞赛不仅为维护体育精神，也旨在保护参与者免受伤害。识别受伤早期迹象，如持续疼痛或肿胀，并及时寻求治疗，可避免小问题演变成严重伤病。
11. Skill Acquisition and Feedback | 技能习得与反馈
Learning a new skill – whether a tennis serve or a gymnastic sequence – progresses through distinct stages. Beginners often start in the cognitive stage, making frequent errors and needing clear demonstrations. With practice, they enter the associative stage, where errors reduce and movements become more consistent. In the autonomous stage, the skill becomes automatic and performed with little conscious thought. Feedback from teachers, peers, or video analysis accelerates this learning process.
学习新技能——无论是网球发球还是体操成套——都经历明确的阶段。初学者通常从认知阶段开始，错误频发并需要清晰的示范。随着练习深入，进入联结阶段，错误减少、动作更连贯。在自主阶段，技能变得自动化，几乎无需意识控制即可完成。来自教师、同伴或视频分析的反馈能加速这一学习过程。
- Cognitive stage – slow, clumsy performance; lots of thinking involved.
- 认知阶段 – 动作缓慢笨拙；需大量思考。
- Autonomous stage – fluent, automatic execution; can focus on tactics.
- 自主阶段 – 动作流畅自动；可专注于战术。
12. Personal Fitness Planning | 个人健身计划
Setting personal fitness goals is a valuable skill for lifelong health. Goals should be SMART: Specific, Measurable, Achievable, Relevant, and Time-bound. A simple fitness plan might include a weekly schedule combining cardiovascular training, strength exercises, and flexibility work. Monitoring progress through a training diary fosters motivation and highlights what works. Year 8 students are encouraged to design a basic plan tailored to their own interests, whether improving speed for football or building endurance for cross-country running.
设定个人健身目标是终身健康的宝贵技能。目标应符合 SMART 原则：具体（Specific）、可衡量（Measurable）、可实现（Achievable）、相关（Relevant）、有时限（Time-bound）。一份简单的健身计划可包括每周安排，结合心血管训练、力量练习与柔韧性练习。通过训练日志监控进度能激发动力并凸显有效方法。鼓励 Year 8 学生根据自身兴趣设计一份基本计划，无论是为足球提高速度，还是为越野跑增强耐力。
