1. Health-Related Components of Fitness | 健康相关体适能要素
Health-related fitness focuses on the physiological factors that contribute to overall health and the ability to perform everyday activities. The five key components are cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. These elements reduce the risk of chronic diseases and improve quality of life.
健康相关体适能关注的是有助于整体健康及完成日常活动的生理因素，其五个关键要素为心肺耐力、肌肉力量、肌肉耐力、柔韧性与身体成分。这些要素可降低慢性病风险并提升生活质量。
Cardiovascular endurance is the ability of the heart, lungs, and blood vessels to deliver oxygen to working muscles during sustained physical activity. It is tested by the multi-stage fitness test (bleep test) or the 12-minute Cooper run. Good cardiovascular endurance allows you to run, swim, or cycle for longer without fatigue.
心肺耐力指心脏、肺部和血管在持续身体活动时向工作肌肉输送氧气的能力，可通过多阶段体能测试（蜂鸣测试）或 12 分钟库珀跑进行评估。良好的心肺耐力使你能更长时间地跑步、游泳或骑行而不易疲劳。
Muscular strength is the maximum force a muscle or muscle group can exert in a single contraction. It is measured by a grip dynamometer test or a one-rep max (1RM) in the weights room. Sports such as weightlifting and rugby scrummaging rely heavily on strength.
肌肉力量是肌肉或肌群在单次收缩中所能产生的最大力量，常用握力计或健身房一次最大重复次数 (1RM) 来测量。举重和橄榄球争球等运动高度依赖力量。
Muscular endurance is the ability of a muscle to sustain repeated contractions or hold a static position over time. The sit-up or press-up bleep test is a common assessment. It is vital for rowing, cycling, and extended bodyweight exercises.
肌肉耐力指肌肉在一段时间内维持重复收缩或保持静态姿势的能力，常采用仰卧起坐或俯卧撑蜂鸣测试评估，对于划船、骑行和长时间自体重训练至关重要。
Flexibility is the range of movement available at a joint. The sit and reach test measures hamstring and lower back flexibility. Good flexibility helps prevent injury, improves posture, and aids performance in gymnastics, dance, and hurdles.
柔韧性是关节可达到的活动范围，通过坐位体前屈测试衡量腘绳肌与下背部的柔韧性。良好的柔韧性有助于预防损伤、改善姿态，并提升体操、舞蹈和跨栏等项目的表现。
Body composition refers to the proportion of body fat, muscle, bone, and other tissues. A healthy body composition usually means a lower percentage of body fat. It is often monitored using body mass index (BMI) or skinfold calipers, though BMI does not distinguish between muscle and fat.
身体成分指体脂、肌肉、骨骼及其他组织的比例。健康的身体成分通常意味着较低的体脂百分比，常用身体质量指数 (BMI) 或皮褶卡尺监测，但 BMI 无法区分肌肉与脂肪。
2. Skill-Related Components of Fitness | 技能相关体适能要素
Skill-related fitness components influence your ability to perform motor tasks and sports skills efficiently. The six recognised components are agility, balance, coordination, power, reaction time, and speed. These are more specific to sporting performance than to general health.
技能相关体适能要素影响你高效完成动作任务和运动技能的能力，公认的六个要素包括灵敏性、平衡、协调性、爆发力、反应时与速度，较之比一般健康更直接地与运动表现相关。
Agility is the ability to change direction quickly while maintaining control. The Illinois agility test is widely used. Games like netball, football, and badminton require rapid changes of direction to evade opponents or reach the shuttle.
灵敏性指快速改变方向同时保持控制的能力，伊利诺伊灵敏性测试被广泛采用。篮网球、足球和羽毛球等比赛都需要快速变向来摆脱对手或接球。
Balance can be static (holding a position still) or dynamic (staying balanced while moving). The standing stork test assesses static balance. Gymnasts, surfers, and ballet dancers need excellent balance.
平衡可分为静态平衡（保持姿势不动）和动态平衡（在移动中维持稳定），立姿白鹤测试用于评估静态平衡。体操运动员、冲浪者和芭蕾舞演员需要极佳的平衡能力。
Coordination is the smooth integration of senses with body parts to produce controlled movement. A hand-eye coordination test like the alternate hand wall toss tests this ability. Catching, hitting, and dribbling all depend on coordination.
协调性是感官与身体部位顺畅配合以产生受控动作的能力，交替手对墙抛接球等测试可评估手眼协调。接球、击球和运球都依赖于协调性。
Power is the product of strength and speed – the ability to exert maximum force in the shortest time. The vertical jump test or standing long jump measures power. Power is essential for a high jump take-off, a fast throw, or a sprint start.
爆发力是力量与速度的乘积，即在最短时间内产生最大力量的能力，可通过纵跳或立定跳远测试衡量。爆发力对跳高踏跳、快速投掷或短跑起跑至关重要。
Reaction time is the time taken to respond to a stimulus, such as a starting gun or a moving ball. The ruler drop test gives a simple measure. Sprint starts and goalkeeper saves demand extremely fast reactions.
反应时是对刺激（如发令枪或移动的球）作出反应所需的时间，直尺下落测试提供了一种简易测量。短跑起跑和守门员扑救需要极快的反应。
Speed is the rate at which a person can move their body or a body part over a distance. It is often measured with a 30-metre sprint time. Speed is vital for a winger in rugby, a 100-metre sprinter, or a fast break in basketball.
速度是个体在单距离上移动身体或身体部位的能力，通常以 30 米冲刺时间衡量。速度对橄榄球边锋、100 米短跑选手或篮球快攻都至关重要。
3. The Skeletal System: Bones and Functions | 骨骼系统：骨骼与功能
The skeleton is the framework of the body, made up of over 200 bones. It serves several crucial functions that support both movement and protection. Year 8 learners must know the names of major bones and the functions of the skeleton.
骨骼是由 200 多块骨头构成的人体框架，具有数项支撑运动和保护的关键功能。Year 8 学生需掌握主要骨骼的名称及骨骼的功能。
The key functions of the skeleton are: support – holding our body upright; protection – shielding vital organs like the brain (skull) and heart/lungs (rib cage); movement – providing attachment points for muscles and acting as levers; mineral storage – storing calcium and phosphorus; and blood cell production – red and white blood cells are made in the bone marrow of long bones.
骨骼的主要功能包括：支持——保持身体直立；保护——保护大脑（颅骨）和心/肺（胸廓）等重要器官；运动——为肌肉提供附着点并充当杠杆；储存矿物质——储存钙和磷；以及血细胞生成——长骨骨髓制造红血细胞和白血细胞。
Important bones to identify and label include: cranium (skull), clavicle (collar bone), scapula (shoulder blade), humerus (upper arm), radius and ulna (forearm), sternum (breastbone), ribs, vertebrae (spine), pelvis, femur (thigh bone), patella (kneecap), tibia and fibula (lower leg), and the tarsals, metatarsals, and phalanges of the foot.
需要识别和标记的重要骨骼包括：颅骨、锁骨、肩胛骨、肱骨、桡骨与尺骨、胸骨、肋骨、椎骨、骨盆、股骨、髌骨、胫骨与腓骨以及足部的跗骨、跖骨和趾骨。
Bones are connected at joints, and many serve as sites where muscles attach via tendons. The skeleton works with the muscular system to enable the body to move effectively. The shape and size of bones influence the types of movement possible at each joint.
骨与骨在关节处连接，许多骨骼部位是肌肉通过肌腱附着的位点。骨骼系统与肌肉系统协同工作，使身体能够有效移动。骨的形状和大小影响着每个关节可实现的活动类型。
4. Muscles and Movement | 肌肉与运动
Muscles produce movement by contracting – they can only pull, never push. They are attached to bones by tendons. Muscles work in pairs across a joint, called antagonist pairs. When one muscle contracts (agonist or prime mover), the opposite muscle relaxes (antagonist) to allow movement.
肌肉通过收缩产生运动——它们只能拉，不能推，通过肌腱附着在骨骼上。肌肉在关节处成对工作，称为拮抗肌对，当一块肌肉收缩（主动肌）时，对侧的肌肉舒张（拮抗肌），从而允许关节活动。
Key voluntary muscles for Year 8 include: deltoid (shoulder), biceps (front of upper arm), triceps (back of upper arm), pectorals (chest), latissimus dorsi (back), abdominals (stomach), quadriceps (front of thigh), hamstrings (back of thigh), gluteals (buttocks), gastrocnemius (calf), and tibialis anterior (shin).
Year 8 需掌握的主要随意肌包括：三角肌、肱二头肌、肱三头肌、胸大肌、背阔肌、腹肌、股四头肌、腘绳肌、臀肌、腓肠肌与胫骨前肌。
For example, when performing a bicep curl, the biceps brachii is the agonist as it contracts concentrically to lift the weight, while the triceps brachii is the antagonist, relaxing to allow the movement. In the lowering phase, the triceps becomes the agonist controlling the descent, and the biceps acts as antagonist.
例如，做肱二头肌弯举时，肱二头肌是主动肌，它通过向心收缩举起重量，而肱三头肌则是拮抗肌，放松以允许动作发生。在放下阶段，肱三头肌成为主动肌控制下放，肱二头肌则充当拮抗肌。
Muscles can also perform other roles: fixator muscles hold a body part steady and provide a stable base for movement. During a bicep curl, the deltoid and trapezius act as fixators to stabilise the shoulder girdle.
肌肉还可扮演其他角色：固定肌保持身体部位稳定，为运动提供稳固的基础。在弯举过程中，三角肌和斜方肌作为固定肌稳定肩带。
5. Joints and Types of Movement | 关节与运动类型
A joint is where two or more bones meet. Joints can be classified by the amount of movement they allow. Synovial joints are freely movable and most relevant in PE. They contain synovial fluid for lubrication, articular cartilage to reduce friction, and ligaments to hold bones together.
关节是两块或多块骨连接的地方，可根据允许的活动范围进行分类。滑膜关节是体育中最重要的活动关节，内含起润滑作用的滑液、减少摩擦的关节软骨以及将骨骼连结起来的韧带。
The main types of synovial joints are: hinge joints (elbow, knee) that allow flexion and extension; ball-and-socket joints (shoulder, hip) that allow flexion, extension, adduction, abduction, rotation, and circumduction; pivot joints (neck/atlas and axis) that allow rotation; and condyloid joints (wrist) that allow flexion, extension, adduction, abduction, and circumduction.
主要的滑膜关节类型有：铰链关节（肘、膝），允许屈和伸；球窝关节（肩、髋），可做屈、伸、内收、外展、旋转与环转；枢轴关节（颈/寰椎与枢椎），允许旋转；以及髁状关节（腕），可做屈、伸、内收、外展和环转。
Movement terminology students should know: flexion – decreasing the angle at a joint (bending the elbow or knee); extension – increasing the angle (straightening a limb); abduction – moving away from the midline of the body (lifting arm sideways); adduction – moving towards the midline; rotation – turning a limb around its long axis (turning head); circumduction – moving the end of a limb in a circle; and plantarflexion and dorsiflexion at the ankle (pointing toes vs. pulling toes up).
学生需掌握的运动术语：屈——减小关节角度（弯曲肘或膝）；伸——增大角度（伸直肢体）；外展——远离身体中线（侧抬手臂）；内收——移向中线；旋转——绕长轴转动（转头）；环转——肢体末端做圆周运动；以及踝关节的跖屈与背屈（绷脚尖 vs. 勾脚尖）。
Linking muscles to movements: the quadriceps extend the knee; the hamstrings flex the knee; the biceps flex the elbow; the triceps extend the elbow; the gluteals extend and rotate the hip; the gastrocnemius plantarflexes the ankle. Understanding these links helps analyse sport movements.
肌肉与运动的关联：股四头肌伸膝，腘绳肌屈膝，肱二头肌屈肘，肱三头肌伸肘，臀肌伸髋与旋髋，腓肠肌跖屈踝关节。理解这些关联有助于分析运动动作。
6. The Cardiovascular System and Exercise | 心血管系统与运动
The cardiovascular system consists of the heart, blood vessels, and blood. It transports oxygen, nutrients, hormones, and waste products around the body. During exercise, the demands on this system increase substantially. Heart rate is the number of times the heart beats per minute (bpm).
心血管系统由心脏、血管和血液组成，负责在全身上下运输氧气、营养物质、激素与废物。运动时，对该系统的需求大大增加。心率指心脏每分钟跳动的次数 (bpm)。
te, calculated as heart rate × stroke volume. Both increase during exercise to deliver more oxygen to the working muscles.
每搏输出量是每次心跳左心室泵出的血液量。心输出量是心脏每分钟泵出的血液总量，计算为心率 × 每搏量。运动时两者均会增加，为工作肌肉输送更多氧气。
Immediate responses to exercise include: increased heart rate (anticipatory rise even before exercise begins), increased stroke volume, increased cardiac output, redistribution of blood flow (vasodilation in active muscles, vasoconstriction in less active areas like the digestive system), and elevated blood pressure.
运动时的即时反应包括：心率升高（甚至运动开始前就有预期性升高）、每搏输出量增加、心输出量增加、血流量重新分配（活动肌肉的血管舒张，消化系统等非活动区域的血管收缩）以及血压升高。
The heart is a double pump: the right side sends deoxygenated blood to the lungs (pulmonary circulation), while the left side sends oxygenated blood to the rest of the body (systemic circulation). The septum divides the two sides. Regular aerobic training makes the heart stronger and more efficient, lowering resting heart rate.
心脏是一个双泵：右侧将缺氧血送到肺部（肺循环），左侧将富氧血送到全身（体循环）。心脏隔膜将两侧分开。定期有氧训练能让心脏变得更强、更有效率，降低静息心率。
7. The Respiratory System and Exercise | 呼吸系统与运动
alveoli. Gas exchange occurs in the alveoli, tiny air sacs surrounded by capillaries, where oxygen diffuses into the blood and carbon dioxide diffuses out.
呼吸系统将氧气带入体内并排出二氧化碳。空气的通路为：鼻/口 → 气管 → 支气管 → 细支气管 → 肺泡。气体交换发生在被毛细血管包围的微小气囊——肺泡中，氧气扩散入血，二氧化碳扩散出。
reath) increase, leading to higher minute ventilation (breathing rate × tidal volume). This ensures more oxygen is taken in and more carbon dioxide is removed.
呼吸频率是每分钟呼吸的次数。运动时，呼吸频率和潮气量（每次呼吸吸入或呼出的空气量）均增加，从而增大了每分钟通气量（呼吸频率 × 潮气量），这确保了更多氧气被摄入、更多二氧化碳被排出。
Key terms include: respiration – (without enough oxygen): glucose → energy + lactic acid. The respiratory and cardiovascular systems work closely together to deliver oxygen and remove waste products.
关键术语包括：呼吸——细胞中从葡萄糖释放能量的过程；有氧呼吸（有氧条件下）：葡萄糖 + O₂ → 能量 + CO₂ + H₂O；无氧呼吸（无足够氧气时）：葡萄糖 → 能量 + 乳酸。呼吸系统与心血管系统密切配合，输送氧气并清除废物。
Diaphragm and intercostal muscles change the volume of the thoracic cavity to cause inspiration (breathing in) and expiration (breathing out). During inspiration, the diaphragm contracts and flattens, and the intercostals lift the ribs, increasing volume and decreasing pressure to draw air in. Expiration is largely passive at rest but becomes active during exercise.
膈肌与肋间肌改变胸腔容积，引起吸气和呼气。吸气时，膈肌收缩变平，肋间肌提肋，增大容积、降低压力，将空气吸入。平静呼气多是被动的，但在运动时变为主动。
8. Principles of Training: FITT | 训练原则：FITT
Planning an effective training programme requires applying the principles of training. The FITT principle helps you design and adjust workouts for specific goals. FITT stands for Frequency, Intensity, Time, and Type.
设计有效的训练计划需要运用训练原则。FITT 原则有助于你根据具体目标设计和调整锻炼方案，其缩写含义为频率、强度、时间与类型。
Frequency refers to how often you train. For general fitness, 3–5 sessions per week are recommended, while for sport-specific skill development, the frequency may be higher. Rest days are essential to allow the body to recover and adapt.
频率指训练的次数。对于一般体适能，建议每周进行 3–5 次练习；而对于运动专项技能发展，频率可能更高。休息日对于身体恢复与适应至关重要。
using heart rate training zones. A simple calculation for maximum heart rate (MHR) is 220 – age. Moderate aerobic exercise should be at 60–80% MHR. For Year 8 students (approx. age 13), MHR ≈ 207 bpm, so a target zone is roughly 124–166 bpm.
强度描述运动的费力程度，可通过心率训练区间来衡量。最大心率 (MHR) 的简易计算公式为 220 – 年龄。中等有氧运动的强度应为最大心率的 60%–80%。对于 Year 8 学生（约 13 岁），MHR ≈ 207 bpm，因此目标区间大约在 124–166 bpm。
Time is the duration of each training session. For cardiovascular improvement, a continuous aerobic session should last at least 20–30 minutes. Shorter, high-intensity interval sessions can be effective for anaerobic fitness.
时间指每次训练的持续时间。为改善心血管功能，连续有氧训练每次应至少持续 20–30 分钟。较短的高强度间歇训练能有效发展无氧能力。
Type is the kind of exercise chosen, which should match the aims and the fitness component being targeted. Examples include continuous running for cardiovascular endurance, circuit training for muscular endurance and strength, interval training for speed, and plyometrics for power.
类型指所选择的运动种类，应与训练目标及所针对的体适能要素相匹配。例如，持续跑针对性心肺耐力，循环训练针对性肌肉耐力与力量，间歇训练针对速度，而增强式训练针对爆发力。
Other important training principles include specificity (training must be relevant to your sport or goal), progressive overload (gradually increasing the demands on the body to cause adaptation), and reversibility (use it or lose it – fitness levels drop when you stop training). Rest and recovery are also vital to prevent overtraining and injury.
其他重要训练原则包括专项性（训练须与运动或目标相关）、渐进超负荷（逐步增大对身体的负荷以引发适应），以及可逆性（用进废退——停止训练后体适能水平下降）。休息与恢复对防止过度训练和损伤同样关键。
9. Warm-Up and Cool-Down | 热身与放松
Every training session or competition should begin with a warm-up and end with a cool-down. A well-structured warm-up prepares the body and mind for exercise, reduces injury risk, and enhances performance. The warm-up typically has three phases: pulse raiser, mobility/dynamic stretching, and skill rehearsal.
每次训练或比赛都应以热身开始、以放松结束。结构合理的热身能使身心为运动做好准备、降低受伤风险并提高表现。热身一般包含三个阶段：提升脉搏、关节活动/动态拉伸与技能预演。
The pulse raiser gradually increases heart rate, breathing rate, and blood flow to muscles. This is often done with light jogging, skipping, or cycling. It literally warms the muscles, making them more pliable. Mobility exercises move joints through their full range of motion, preparing ankles, hips, shoulders, and spine.
脉搏提升阶段逐步提高心率、呼吸频率及肌肉血流量，通常通过轻慢跑、跳跃或骑自行车完成。它切实地使肌肉升温，令其更具柔韧性。关节活动练习使脚踝、髋部、肩部和脊柱等关节在全活动范围内活动，做好预热准备。
Dynamic stretching uses controlled, sport-specific movements, such as leg swings, lunges with a twist, or high knees. Static stretching (holding a stretch) should be avoided during warm-ups as it can temporarily reduce power, but it is well suited for the cool-down.
动态拉伸采用受控的、与运动相关的动作，例如摆腿、转体弓步或高抬腿。热身时应避免静态拉伸（保持拉伸姿势），因为它可能暂时降低爆发力；而静态拉伸则非常适合用在放松环节。
The cool-down helps the body return to its resting state gradually. It typically involves light aerobic activity (a gentle jog or walk) to remove waste products such as lactic acid and to prevent blood pooling. This is followed by static stretching, holding each stretch for about 20–30 seconds, to improve flexibility and reduce muscle soreness.
放松环节帮助身体逐渐恢复到静息状态，通常包含轻有氧活动（慢跑或步行），以清除乳酸等废物并防止血液淤积。随后进行静态拉伸，每个拉伸姿势保持 20–30 秒，以改善柔韧性并减轻肌肉酸痛。
10. Nutrition and Hydration | 营养与补水
A balanced diet provides the energy and nutrients required for growth, daily activity, and sport performance. The Eatwell Guide groups foods into categories: fruit and vegetables; starchy carbohydrates (potatoes, bread, rice, pasta); proteins (meat, fish, eggs, beans); dairy and alternatives; and oils and spreads. Good nutrition aids recovery and concentration.
均衡饮食为生长、日常活动和运动表现提供所需的能量与营养素。《饮食健康指南》将食物分为几类：水果蔬菜；淀粉类碳水化合物（土豆、面包、大米、意面）；蛋白质（肉、鱼、蛋、豆类）；奶制品及替代品；以及油脂和涂抹酱。良好营养有助于恢复和专注。
Carbohydrates are the body's main fuel source, especially during high-intensity exercise. They are stored in muscles and the liver as glycogen. Eating complex carbohydrates like whole grains provides sustained energy release. Fats provide a slower, long-lasting energy source for low to moderate intensity activity and protect organs.
碳水化合物是身体的主要燃料来源，尤其在高强度运动中。它们以糖原形式储存在肌肉和肝脏中。摄入全谷物等复合碳水化合物能提供持续的能量释放。脂肪则可提供缓慢持久的能量，适用于中低强度活动，并有保护器官的作用。
Protein is essential for muscle growth and repair. After exercise, consuming protein helps rebuild muscle fibres that have been stressed during training. Good sources include lean meat, poultry, fish, eggs, milk, yogurt, and plant-based options like lentils and tofu.
蛋白质对于肌肉生长与修复至关重要。运动后摄入蛋白质有助于重建在训练中受压的肌纤维。优质来源包括瘦肉、禽肉、鱼、蛋、奶、酸奶，以及小扁豆和豆腐等植物性选择。
Hydration is critical before, during, and after exercise. Water helps regulate body temperature through sweating and transports nutrients. Dehydration leads to a drop in performance, poor coordination, fatigue, and even heat stroke. Isotonic sports drinks can help replace fluids, electrolytes, and carbohydrates during prolonged intense activity, but water is usually sufficient for most sessions.
补水在运动前、中、后都至关重要。水通过出汗帮助调节体温并运输营养物质。脱水会导致表现下降、协调性变差、疲劳甚至中暑。等渗运动饮料可在长时间高强度运动中帮助补充液体、电解质和碳水化合物，但大多数训练中饮用水便已足够。
11. Goal Setting and Feedback | 目标设定与反馈
Sport psychology introduces mental strategies that improve performance and motivation. Goal setting is a powerful tool to direct effort and track progress. Goals should be SMARTER: Specific, Measurable, Achievable, Realistic/Relevant, Time-bound, Evaluated, and Re-evaluated.
运动心理学提供了提升表现和动力的心理策略。目标设定是一种引导努力方向、追踪进步的有力工具。目标应遵循 SMARTER 原则：具体、可衡量、可达成、现实/相关、有时限、可评估和可再评估。
For example, instead of 'get better at football', a SMARTER goal could be: 'Increase my instep passing accuracy to 80% over 20 attempts in practice by the end of this half term.' This makes it clear and trackable. Setting short-term goals acts as stepping stones towards bigger long-term ambitions.
例如，与其设定“提高足球水平”，一个 SMARTER 目标可以是：“在本半学期结束前，将我的脚内侧传球准确率提升至 20 次练习中达到 80%。” 这样目标既清晰又可追踪。设定短期目标是实现更大长期愿望的垫脚石。
Feedback is information received about the outcome of a performance. It can be intrinsic (from within, how the movement felt – kinaesthetic) or extrinsic (from an outside source, such as a coach, teacher, or video analysis). Knowledge of results (KR) tells you the outcome, like if the ball went in the net, while knowledge of performance (KP) tells you about the quality of the movement, such as 'your follow-through was short'.
反馈是关于表现结果的信息。它可以是内在的（来自自身，即动作感觉——动觉感受），也可以是外在的（来自外部，如教练、老师或视频分析）。结果反馈 (KR) 告知结果，如球是否入网；而表现反馈 (KP) 告知动作质量，如“你的跟随动作太短”。
Effective feedback is constructive, specific, and gives clear guidance on how to improve. Beginners often benefit more from extrinsic KP feedback, while experienced performers can use intrinsic feedback for fine-tuning. Regularly reviewing goals and feedback helps athletes stay motivated and make continuous improvements.
有效的反馈应具有建设性、具体，并就如何改进给出清晰指导。初学者往往从外在的表现反馈中获益更多，而有经验的选手则可利用内在反馈进行微调。定期回顾目标和反馈有助于运动员保持动力并持续进步。
