1. The Skeletal System | 骨骼系统

The skeleton provides five key functions: support for the body, protection of vital organs (e.g. cranium protects the brain, ribs protect the heart and lungs), movement by providing attachment points for muscles, storage of minerals such as calcium and phosphorus, and blood cell production in the bone marrow. Bones are classified by shape: long bones (femur, humerus), short bones (carpals, tarsals), flat bones (cranium, sternum, ribs), irregular bones (vertebrae), and sesamoid bones (patella).

骨骼有五大关键功能：支撑身体、保护重要器官（如颅骨保护大脑，肋骨保护心脏和肺）、通过为肌肉提供附着点来实现运动、储存钙和磷等矿物质，以及在骨髓中生成血细胞。骨骼按形状分类：长骨（股骨、肱骨）、短骨（腕骨、跗骨）、扁骨（颅骨、胸骨、肋骨）、不规则骨（椎骨）和籽骨（髌骨）。

A synovial joint is a freely movable joint. Key structures include the synovial membrane, which secretes synovial fluid to lubricate the joint, articular cartilage to reduce friction and absorb shock, ligaments to connect bone to bone, and tendons to attach muscle to bone. Hinge joints (elbow, knee) allow flexion and extension; ball‑and‑socket joints (shoulder, hip) allow flexion, extension, abduction, adduction, rotation and circumduction.

滑膜关节是可自由活动的关节。关键结构包括分泌滑液以润滑关节的滑膜、减少摩擦和吸收冲击的关节软骨、连接骨与骨的韧带以及将肌肉附着于骨的肌腱。铰链关节（肘、膝）允许屈曲和伸展；球窝关节（肩、髋）允许屈曲、伸展、外展、内收、旋转和环转。

2. The Muscular System | 肌肉系统

There are three types of muscle tissue: cardiac muscle (involuntary, found only in the heart), smooth muscle (involuntary, found in blood vessels and digestive organs), and skeletal muscle (voluntary, attached to bones and responsible for movement). Major skeletal muscles include the biceps, triceps, deltoid, pectorals, latissimus dorsi, abdominals, gluteals, quadriceps, hamstrings, and gastrocnemius. Muscles work in antagonistic pairs; when the biceps contracts (agonist), the triceps relaxes (antagonist), and vice versa to produce controlled movement at a joint.

肌肉组织有三种类型：心肌（不随意肌，仅位于心脏）、平滑肌（不随意肌，分布于血管和消化器官）和骨骼肌（随意肌，附着于骨上并负责运动）。主要的骨骼肌包括肱二头肌、肱三头肌、三角肌、胸大肌、背阔肌、腹肌、臀肌、股四头肌、腘绳肌和腓肠肌。肌肉以拮抗对的形式工作；当肱二头肌收缩（主动肌）时，肱三头肌放松（拮抗肌），反之亦然，从而在关节处产生受控运动。

Muscular contractions are described as isotonic (the muscle changes length while tension remains constant – e.g. lifting a weight), isometric (no change in length, e.g. holding a plank), and isokinetic (rarely tested at GCSE, refers to constant speed using specialist equipment). Muscle fibre types include slow‑twitch (Type I) fibres suited to endurance activities, and fast‑twitch (Type IIa and IIx) fibres for explosive, high‑intensity activities. Athletes can shift fibre characteristics through specific training.

肌肉收缩可分为等张收缩（肌肉长度改变而张力恒定，如举重）、等长收缩（长度不变，如平板支撑）和等速收缩（在 GCSE 中很少测查，指借助专业设备保持恒定速度）。肌纤维类型包括适合耐力活动的慢肌纤维（I 型），以及适合爆发性高强度活动的快肌纤维（IIa 和 IIx 型）。运动员可通过专项训练改变纤维特性。

3. The Cardiovascular System | 心血管系统

The heart has four chambers: right atrium, right ventricle, left atrium, and left ventricle. Deoxygenated blood flows from the body into the right atrium, then to the right ventricle, and is pumped to the lungs via the pulmonary artery. Oxygenated blood returns via the pulmonary vein into the left atrium and is pumped by the left ventricle through the aorta to the rest of the body. Arteries carry blood away from the heart at high pressure; veins return blood at low pressure and contain valves; capillaries are the site of gaseous exchange.

心脏有四个腔室：右心房、右心室、左心房和左心室。缺氧血从身体流入右心房，再到右心室，经肺动脉泵入肺部。富氧血经肺静脉回流至左心房，再由左心室通过主动脉泵送至全身。动脉在高压下将血液运离心脏；静脉在低压下将血液送回心脏并含有瓣膜；毛细血管是气体交换的场所。

Key cardiac values: heart rate (HR) is the number of beats per minute; stroke volume (SV) is the volume of blood pumped per beat; cardiac output (Q) = HR × SV. During exercise, HR and SV increase, raising Q. Recovery rate indicates fitness. The Karvonen formula calculates a target heart rate for training:

Target HR = Resting HR + (Intensity × (HRₘₐₓ – Resting HR))

关键心脏指标：心率（HR）是每分钟心跳次数；每搏输出量（SV）是每次心跳泵出的血量；心输出量（Q）= 心率 × 每搏输出量。运动时心率和每搏输出量均增加，使心输出量升高。心率恢复速度可反映体能水平。卡沃宁公式用于计算训练目标心率：

目标心率 = 静息心率 + (强度 × (最大心率 – 静息心率))

Regular training lowers resting HR and increases SV, making the heart more efficient.

规律训练可降低静息心率并增加每搏输出量，使心脏效率更高。

4. The Respiratory System | 呼吸系统

Air travels through the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles to reach the alveoli, where gas exchange occurs. Oxygen diffuses from the alveoli into the blood in surrounding capillaries, and carbon dioxide diffuses from the blood into the alveoli to be exhaled. The process is driven by differences in partial pressure.

空气依次通过鼻腔、咽、喉、气管、支气管和细支气管到达肺泡，在那里进行气体交换。氧气从肺泡扩散进入周围毛细血管的血液中，二氧化碳则从血液扩散进入肺泡并被呼出。这一过程由分压差驱动。

During inhalation, the diaphragm and intercostal muscles contract, increasing chest volume and reducing pressure so air flows in. During exhalation, these muscles relax, decreasing volume and forcing air out. Tidal volume is the amount of air inhaled or exhaled in a normal breath; vital capacity is the maximum volume of air that can be exhaled after a maximal inhalation. Both increase with regular aerobic training.

吸气时，膈肌和肋间肌收缩，胸腔容积增大，压力降低，空气进入。呼气时，这些肌肉放松，容积减小，将空气压出。潮气量是正常呼吸时吸入或呼出的空气量；肺活量是最大吸气后能呼出的最大空气量。两者在有规律的有氧训练后都会增加。

VO₂ max (maximal oxygen uptake) is the highest rate at which the body can take up and use oxygen during intense exercise. It is a key indicator of aerobic endurance and can be improved by sustained aerobic training.

VO₂ ₘₐₓ（最大摄氧量）是身体在剧烈运动中吸收和利用氧气的最高速率。它是评价有氧耐力的关键指标，可通过持续的有氧训练得以提高。

5. Movement Analysis | 动作分析

Levers help us understand how movements are created. A first‑class lever has the fulcrum between the effort and the load (e.g. a heading movement in football where the neck muscles act on the head). A second‑class lever has the load between the fulcrum and the effort (e.g. standing on tiptoe at the ankle). A third‑class lever has the effort between the fulcrum and the load – the most common in the body (e.g. biceps curl at the elbow). The mechanical advantage differs, with third‑class levers favouring speed and range of motion.

杠杆帮助我们理解运动是如何产生的。第一类杠杆的支点位于力与阻力之间（如足球头球动作，颈部肌肉作用于头部）。第二类杠杆的阻力位于支点和力之间（如用脚尖站立，踝关节处）。第三类杠杆的力位于支点和阻力之间——这是人体中最常见的（如肘部肱二头肌弯举）。不同的杠杆提供的机械优势不同，第三类杠杆有利于速度和运动幅度。

Planes and axes describe movement in three dimensions. The sagittal plane divides the body into left and right, and movements such as flexion and extension occur around a frontal axis (e.g. forward roll). The frontal plane divides the body into front and back; abduction and adduction occur around a sagittal axis (e.g. cartwheel). The transverse plane divides the body into top and bottom; rotational movements occur around a vertical axis (e.g. a pirouette in dance).

平面和轴用于描述三维空间中的运动。矢状面将身体分为左右两部分，屈曲和伸展等运动围绕额状轴进行（如前滚翻）。额状面将身体分为前后两部分，外展和内收围绕矢状轴进行（如侧手翻）。横切面将身体分为上下两部分，旋转运动围绕垂直轴进行（如舞蹈中的回旋动作）。

6. Components of Fitness | 体能组成

Health‑related components include: body composition (ratio of fat mass to lean mass), cardiovascular endurance (ability of heart and lungs to deliver oxygen during sustained activity), muscular strength (maximum force a muscle can exert), muscular endurance (ability to repeat contractions without fatigue), and flexibility (range of motion at a joint).

与健康相关的体能组成包括：身体成分（脂肪与瘦体重的比例）、心肺耐力（持续运动中输送氧气的能力）、肌肉力量（肌肉能产生的最大力量）、肌肉耐力（重复收缩而不疲劳的能力）和柔韧性（关节活动范围）。

Skill‑related components include: agility (ability to change direction quickly while maintaining control), balance (maintaining centre of mass over base of support), coordination (smooth use of senses and body parts), reaction time (time taken to respond to a stimulus), speed (rate of movement or distance per unit time), and power (product of strength and speed – explosive strength). Each sport demands a different blend of these components.

与技能相关的体能组成包括：敏捷性（快速变向并保持控制的能力）、平衡力（保持身体重心在支撑面之上）、协调性（感官与身体部位的协调配合）、反应时（对刺激作出反应的时间）、速度（移动速率或单位时间的距离）和爆发力（力量与速度的乘积——爆发力）。不同的运动对这些体能组成有不同的需求组合。

7. Principles of Training | 训练原则

The SPOR / FITT principles guide effective programme design. Specificity means training must be relevant to the sport or activity. Progression involves gradually increasing the training load as the body adapts. Overload requires the body to work harder than normal to stimulate improvement – achieved by manipulating Frequency, Intensity, Time and Type (FITT). Reversibility warns that fitness gains are lost when training stops or become insufficient. Individual differences recognise that everyone responds differently to training, so programmes must be personalised.

SPOR / FITT 原则指导有效的训练计划设计。针对性指训练必须与运动或活动相关。渐进性指随着身体适应逐渐增加训练负荷。超负荷要求身体比平时更努力地工作以刺激进步——这可通过调整频率、强度、时间和类型（FITT）来实现。可逆性警告，当训练停止或不足时，体能增益会丢失。个体差异性承认每个人对训练的反应不同，因此训练计划必须个性化。

For example, to improve cardiovascular endurance using continuous training, a runner might increase frequency from 2 to 3 sessions per week, increase duration from 20 to 30 minutes, and maintain intensity at a target heart rate of 60‑80% of HRₘₐₓ.

例如，要用持续训练提升心肺耐力，跑者可以将频率从每周 2 次增加到 3 次，持续时间从 20 分钟增加到 30 分钟，并将强度保持在最大心率的 60‑80% 的目标心率。

8. Methods of Training | 训练方法

Continuous training involves steady‑state exercise without rest (e.g. long‑distance running, cycling) and develops aerobic endurance. Interval training alternates periods of high‑intensity work with rest or low‑intensity recovery, improving both aerobic and anaerobic capacity. Fartlek training is a combination of continuous and interval training with varied speeds and terrains, ideal for games players. Circuit training uses a series of different exercises at stations, developing multiple fitness components. Weight training uses resistance to develop muscular strength and endurance; it can be organised by reps, sets and load.

持续训练指无间歇的稳态运动（如长跑、骑行），可发展有氧耐力。间歇训练将高强度运动阶段与休息或低强度恢复交替进行，能同时提升有氧和无氧能力。法特莱克训练结合了持续训练和间歇训练，并变换速度和地形，非常适合球类运动员。循环训练利用多个不同练习的站点发展多种体能素质。重量训练利用阻力来发展肌肉力量和耐力，可通过次数、组数和负重来安排。

Plyometrics involve explosive jumping and bounding exercises to develop power (e.g. box jumps). High‑Intensity Interval Training (HIIT) involves short bursts of maximal effort followed by brief recovery. All methods should be matched to the goals and components of fitness needed for the performer’s sport.

增强式训练（Plyometrics）涉及爆发性的跳跃和弹跳练习，以发展爆发力（如跳箱）。高强度间歇训练（HIIT）包括短时间最大努力运动后接短暂恢复。所有训练方法都应与运动员所在运动项目需要达成的目标和体能组成相匹配。

9. Sports Psychology | 运动心理学

Skills can be classified along several continua: open (environment constantly changes, e.g. a pass in football) versus closed (stable, predictable environment, e.g. a golf putt); complex (many sub‑routines, e.g. a gymnastics routine) versus simple; self‑paced (performer controls timing) versus externally‑paced; and gross (large muscle groups) versus fine (precise movements). Coaches use these classifications to select appropriate practice structures.

技能可以根据多个连续体分类：开放式（环境持续变化，如足球传球）与闭锁式（环境稳定、可预测，如高尔夫推杆）；复杂技能（有许多子程序，如体操成套动作）与简单技能；自我步调（运动员控制时机）与外部步调；粗大技能（动用大肌肉群）与精细技能。教练利用这些分类选择合适的练习结构。

Feedback is essential for skill learning. Intrinsic feedback comes from the performer’s own senses; extrinsic feedback is provided by an external source (coach, video). Knowledge of results (KR) tells the outcome (score, hit or miss); knowledge of
