2. Recalling Year 7: The Skeletal System | 回顾 Year 7：骨骼系统
The human skeleton provides support, protection, movement, blood cell production and mineral storage. In Year 7 you learned the names of major bones such as the femur, tibia, humerus, radius, pelvis, sternum and cranium.
人体骨骼提供支撑、保护、运动、造血和储存矿物质等功能。在 Year 7 你学习了主要骨骼的名称，例如股骨、胫骨、肱骨、桡骨、骨盆、胸骨和颅骨。
In Year 8 we classify bones by shape: long bones (e.g. femur) act as levers for movement; short bones (e.g. carpals) provide stability; flat bones (e.g. sternum) protect organs; and irregular bones (e.g. vertebrae) have special shapes for protection and support.
在 Year 8 我们将骨骼按形状分类：长骨（如股骨）作为运动的杠杆；短骨（如腕骨）提供稳定性；扁骨（如胸骨）保护器官；不规则骨（如椎骨）具有特殊的形状以实现保护与支撑。
Joints are where two or more bones meet. You will revise synovial joints such as the hinge (elbow, knee) and ball-and-socket (shoulder, hip). Each joint type allows specific ranges of motion that influence sporting actions like throwing or kicking.
关节是两块或以上骨骼连接的地方。你将复习滑膜关节，如枢纽关节（肘、膝）和球窝关节（肩、髋）。每种关节类型允许特定的运动范围，影响着投掷或踢球等运动动作。
3. Muscular System and Movement | 肌肉系统与运动
Muscles work by contracting and pulling on bones to create movement. Year 7 introduced key muscles: biceps, triceps, quadriceps, hamstrings, abdominals and deltoid. In Year 8 we explore how these muscles act in pairs called antagonistic pairs.
肌肉通过收缩并牵拉骨骼来产生运动。Year 7 介绍了主要肌肉：肱二头肌、肱三头肌、股四头肌、腘绳肌、腹肌和三角肌。在 Year 8 我们将探究这些肌肉如何成对工作，称为拮抗肌对。
When the biceps contracts to bend the elbow, it is the agonist; the triceps relaxes and acts as the antagonist. Understanding these roles helps you analyse movements in sports like tennis, swimming or cycling.
当肱二头肌收缩弯曲肘关节时，它是主动肌；肱三头肌放松并作为拮抗肌。理解这些角色有助于你分析网球、游泳或自行车等运动中的动作。
There are three muscle types: skeletal (voluntary) muscles for movement, smooth (involuntary) muscles in organs, and cardiac muscle in the heart. Our focus is on skeletal muscle and how it adapts to training.
肌肉有三种类型：骨骼肌（随意肌）负责运动、平滑肌（不随意肌）在内脏中、以及心肌在心脏。我们的重点是骨骼肌以及它如何对训练产生适应性变化。
4. The Cardiovascular System: Heart and Circulation | 心血管系统：心脏与循环
The cardiovascular system consists of the heart, blood and blood vessels (arteries, veins, capillaries). It transports oxygen, nutrients and hormones, and removes waste products like carbon dioxide.
心血管系统由心脏、血液和血管（动脉、静脉、毛细血管）组成。它输送氧气、营养物质和激素，并清除二氧化碳等代谢废物。
In Year 7 you learned that the heart has four chambers: right atrium, right ventricle, left atrium and left ventricle. Year 8 adds the sequence of blood flow around the double circulatory system: the pulmonary circuit to the lungs and the systemic circuit to the body.
在 Year 7 你学习了心脏有四个腔室：右心房、右心室、左心房和左心室。Year 8 增加双循环系统中血液流动的顺序：去往肺部的肺循环和去往全身的体循环。
During exercise, heart rate increases to deliver more oxygen. You will learn to measure heart rate and calculate a simple target zone.
运动中，心率增加以输送更多氧气。你将学会测量心率并计算简单的目标心率区间。
Maximum Heart Rate = 220 – age
最大心率 = 220 – 年龄
5. The Respiratory System: Breathing and Gas Exchange | 呼吸系统：呼吸与气体交换
Breathing brings oxygen into the lungs and removes carbon dioxide. The main structures are the trachea, bronchi, bronchioles and alveoli. In Year 8 we focus on the process of gas exchange at the alveoli.
呼吸将氧气带入肺部并排出二氧化碳。主要结构有气管、支气管、细支气管和肺泡。在 Year 8 我们重点关注肺泡处的气体交换过程。
Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. A large surface area and thin walls of the alveoli make this exchange efficient.
氧气从肺泡扩散进入血液，同时二氧化碳从血液扩散进入肺泡被呼出。大表面积和肺泡薄壁使得这一交换高效进行。
During exercise, breathing rate and depth increase to meet the higher demand for oxygen. You will interpret data from spirometer traces and understand terms such as tidal volume and vital capacity.
运动时，呼吸频率和深度增加以满足更高的氧气需求。你将解读肺活量计曲线的数据，并理解潮气量、肺活量等术语。
6. Health-Related Fitness Components | 健康相关体适能要素
Health-related fitness is important for maintaining a healthy body and reducing disease risk. The five key components are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition.
健康相关体适能对于保持身体健康和降低疾病风险很重要。五个关键要素是：心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。
Cardiovascular endurance is the ability of the heart and lungs to supply oxygen during sustained activity; muscular strength is the maximum force a muscle can exert; muscular endurance is the ability to repeat contractions without fatigue.
心血管耐力指心脏和肺部在持续活动中供氧的能力；肌肉力量指肌肉能施加的最大力量；肌肉耐力指重复收缩而不会疲劳的能力。
Flexibility refers to the range of motion around a joint, and body composition describes the relative percentage of muscle, fat and bone. You will assess these components using simple tests such as the bleep test, grip dynamometer and sit-and-reach.
柔韧性指关节周围的活动范围，身体成分描述肌肉、脂肪和骨骼的相对百分比。你将使用简单的测试评估这些要素，例如蜂鸣测试、握力计和坐位体前屈。
7. Skill-Related Fitness Components | 技能相关体适能要素
Skill-related fitness helps you perform well in sports and games. The six components are agility, balance, coordination, power, reaction time and speed. In Year 8 you will link each component to specific sporting examples.
技能相关体适能帮助你在运动和比赛中表现出色。六个要素是：敏捷性、平衡、协调、爆发力、反应时和速度。在 Year 8 你将把每个要素与具体的运动实例联系起来。
Agility is the ability to change direction quickly – essential for rugby or netball. Balance helps gymnasts hold a handstand; coordination integrates senses and body parts, as in a tennis serve. Power combines strength and speed, needed for a basketball jump shot.
敏捷性是快速改变方向的能力，对橄榄球或无挡板篮球至关重要。平衡帮助体操运动员保持倒立；协调性将感官与身体部位整合，比如网球发球。爆发力结合力量与速度，是篮球跳投所需要的。
Reaction time is the time taken to respond to a stimulus, crucial for a sprint start; speed is the ability to move body parts quickly. Practicing drills that target these components can improve your overall sports performance.
反应时是对刺激作出反应所需的时间，对短跑起跑至关重要；速度是快速移动身体部位的能力。针对这些要素的练习可以提高你的整体运动表现。
8. Principles of Training and Exercise | 训练与锻炼原则
To improve fitness, training must follow key principles. The SPORT acronym helps you remember: Specificity, Progression, Overload, Reversibility and Tedium (variety). Year 8 introduces these principles and how to apply them.
要提高体适能，训练必须遵循关键原则。SPORT 首字母缩写可以帮助记忆：专项性、渐进性、超负荷、可逆性和趣味性（多样性）。Year 8 介绍这些原则及如何应用。
Specificity means training should match the sport and energy systems used. Progression requires gradually increasing difficulty. Overload can be achieved by manipulating Frequency, Intensity, Time and Type – the FITT principle.
专项性意味着训练应匹配运动项目和所使用的能量系统。渐进性需要逐步增加难度。超负荷可以通过改变频率、强度、时间和类型——即 FITT 原则—来实现。
If you stop training, reversibility occurs, causing fitness to decline. Including variety prevents tedium and maintains motivation. You will design a simple personal exercise plan applying SPORT and FITT.
如果你停止训练，可逆性就会发生，导致体适能下降。包含多样性可以防止枯燥并保持动力。你将应用 SPORT 和 FITT 原则设计一个简单的个人锻炼计划。
9. Nutrition and Hydration for Performance | 运动营养与补水
A balanced diet fuels exercise and aids recovery. The main nutrients are carbohydrates, proteins, fats, vitamins, minerals, fibre and water. Each has a specific role in the body.
均衡饮食为运动提供能量并促进恢复。主要营养素包括碳水化合物、蛋白质、脂肪、维生素、矿物质、纤维和水。每种在体内都有特定的作用。
| Nutrient | Primary Function | Examples |
|---|---|---|
| Carbohydrates | Main energy source | Pasta, rice, bread |
| Protein | Growth and repair of muscle | Chicken, beans, eggs |
| Fats | Slow-release energy, insulation | Avocados, nuts, oils |
Carbohydrates are the body’s preferred fuel during high-intensity exercise. Protein repairs damaged muscle fibres after training. Fats provide energy for long-duration, low-intensity activities. Vitamins and minerals support immune function and bone health.
碳水化合物是高强度运动时身体的首选燃料。蛋白质在训练后修复受损肌纤维。脂肪为长时间、低强度的活动提供能量。维生素和矿物质支持免疫功能和骨骼健康。
Hydration is equally vital. Even a small fluid loss can impair performance. Water regulates body temperature and transports nutrients. You will learn to plan pre-event meals and monitor urine colour as a hydration indicator.
补水同样至关重要。即使少量液体流失也会损害运动表现。水调节体温并输送营养。你将学习规划赛前饮食，以及通过观察尿液颜色来判断水合状态。
10. Injury Prevention and Safe Practice | 损伤预防与安全实践
Understanding how to prevent injuries is a core part of Year 8 PE. Common sports injuries include sprains, strains, fractures, cuts and bruises. Prevention starts with a proper warm-up and cool-down.
了解如何预防损伤是 Year 8 体育的核心内容之一。常见的运动损伤包括扭伤、拉伤、骨折、割伤和挫伤。预防始于适当的热身和整理活动。
A warm-up gradually increases heart rate, warms muscles and improves joint mobility. It often includes pulse-raising activities, dynamic stretches and sport-specific drills. A cool-down gradually lowers heart rate and includes static stretches to aid recovery and flexibility.
热身逐步提高心率，温暖肌肉并改善关节活动度。通常包括提高心率的运动、动态拉伸和专项运动练习。整理活动逐步降低心率，并包含静态拉伸以促进恢复和柔韧性。
Using correct equipment, playing by the rules and understanding safe techniques also reduce injury risk. You will study the RICE method (Rest, Ice, Compression, Elevation) for treating minor soft tissue injuries.
使用正确的装备、遵守规则和掌握安全的技术也能降低受伤风险。你将学习用于处理轻度软组织损伤的 RICE 方法（休息、冰敷、加压、抬高）。
11. Introduction to Sports Psychology | 运动心理学入门
Mental factors influence physical performance. In Year 8 you are introduced to basic sports psychology concepts such as motivation, arousal, anxiety and feedback.
心理因素影响着身体表现。在 Year 8 你会接触到基本的运动心理学概念，如动机、唤醒、焦虑和反馈。
Intrinsic motivation comes from internal satisfaction, while extrinsic motivation involves external rewards like trophies. Optimal arousal levels vary between sports – a gymnast needs calm concentration, while a rugby player benefits from higher arousal.
内在动机来自于内心的满足感，而外在动机涉及奖杯等外部奖励。最佳唤醒水平因运动而异——体操运动员需要冷静专注，而橄榄球运动员可从较高的唤醒水平中获益。
Anxiety can negatively affect performance if not managed. Simple techniques such as deep breathing and positive self-talk can help. External feedback from a coach and internal feedback from your own senses are both important for improving skills.
焦虑如果得不到控制，会对运动表现产生负面影响。深呼吸和积极的自我对话等简单技巧可提供帮助。来自教练的外部反馈和来自自身感觉的内部反馈，对于技能提升都很重要。
12. Self-Evaluation and Setting Goals | 自我评估与设定目标
To make progress in PE, you need to reflect on your strengths and weaknesses. Year 8 encourages you to set SMART goals: Specific, Measurable, Achievable, Relevant and Time-bound.
要在体育中取得进步，你需要反思自己的优势与不足。Year 8 鼓励你设定 SMART 目标：具体的、可衡量的、可实现的、相关的、有时限的。
For example, instead of saying ‘I want to run faster’, a SMART goal would be ‘I will reduce my 800m time by 8 seconds over the next six weeks by attending two interval training sessions per week.’
例如，与其说“我想跑得更快”，一个 SMART 目标可以是“我将在接下来的六周内，通过每周参加两次间歇训练，将 800 米成绩提高 8 秒。”
You will learn to conduct simple fitness tests, record your results and adjust your training programme based on evidence. This approach builds independence and long-term health habits.
你将学习进行简单的体适能测试，记录结果并根据数据调整训练计划。这种方法能培养独立性和长期的健康习惯。
