1. Skeletal System Functions and Bones | 骨骼系统的功能与骨骼
The skeletal system provides support, protection, movement, mineral storage and blood cell production. The four main types of bone – long, short, flat and irregular – each serve different purposes. Key bones to remember include the cranium, clavicle, scapula, humerus, radius, ulna, vertebrae, pelvis, femur, patella, tibia and fibula. Joint classification features fibrous (immovable), cartilaginous (slightly movable) and synovial (freely movable) joints, with synovial joints being the most relevant in sport.
骨骼系统提供支撑、保护、运动、矿物质储存和血细胞生成等功能。骨骼主要分为长骨、短骨、扁骨和不规则骨四类，各具用途。需要记住的关键骨骼包括颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、椎骨、骨盆、股骨、髌骨、胫骨和腓骨。关节分类包括纤维关节（不动）、软骨关节（微动）和滑膜关节（自由活动），其中滑膜关节在运动中最重要。
- Protection: skull shields the brain; ribcage safeguards the heart and lungs.
- 保护作用：颅骨保护大脑；肋骨保护心脏和肺。
- Movement: bones serve as levers, with muscles pulling on them to create motion.
- 运动作用：骨骼充当杠杆，肌肉牵拉骨骼产生动作。
- Synovial joint features: synovial fluid lubricates, articular cartilage reduces friction, ligaments connect bone to bone.
- 滑膜关节特点：滑液起润滑作用，关节软骨减少摩擦，韧带连接骨与骨。
2. Muscular System Structure and Function | 肌肉系统的结构与功能
Muscles are made of fibres that contract to produce movement. Skeletal muscles work in antagonistic pairs: while the agonist (prime mover) contracts, the antagonist relaxes. For example, during elbow flexion the biceps is the agonist and the triceps is the antagonist. Muscle types include voluntary (skeletal), involuntary (smooth) and cardiac muscle. Major muscles to know are the deltoid, pectorals, latissimus dorsi, abdominals, quadriceps, hamstrings, gastrocnemius, gluteals and tibialis anterior.
肌肉由能收缩产生运动的纤维构成。骨骼肌以拮抗肌对的形式工作：当主动肌（原动肌）收缩时，拮抗肌放松。例如，肘关节屈曲时，肱二头肌是主动肌，肱三头肌是拮抗肌。肌肉类型包括随意肌（骨骼肌）、不随意肌（平滑肌）和心肌。需要掌握的主要肌肉有三角肌、胸肌、背阔肌、腹肌、股四头肌、腘绳肌、腓肠肌、臀肌和胫骨前肌。
- Antagonistic pairs: quadriceps and hamstrings at the knee; biceps and triceps at the elbow.
- 拮抗肌对：膝关节的股四头肌与腘绳肌；肘关节的肱二头肌与肱三头肌。
- Muscle contractions: isotonic (concentric – shortening, eccentric – lengthening) and isometric (length stays same).
- 肌肉收缩类型：等张收缩（向心收缩 – 缩短，离心收缩 – 伸长）和等长收缩（长度不变）。
- Role of tendons: attach muscle to bone, transmitting force for movement.
- 肌腱的作用：将肌肉连接到骨骼，传递力量以实现运动。
3. Cardiovascular System and Responses to Exercise | 心血管系统及其对运动的反应
The cardiovascular system consists of the heart, blood and blood vessels. Its main functions are oxygen delivery (via red blood cells), carbon dioxide removal, nutrient transport, temperature regulation and protection against disease. During exercise, heart rate, stroke volume and cardiac output increase. Blood is redistributed, with more blood directed to working muscles and less to organs such as the stomach. Long-term adaptations include a lower resting heart rate, increased stroke volume and cardiac hypertrophy.
心血管系统由心脏、血液和血管组成。其主要功能包括氧气输送（通过红细胞）、二氧化碳清除、营养运输、体温调节和疾病防护。运动时，心率、每搏输出量和心输出量均增加。血液重新分配，更多血液流向工作肌肉，较少流向胃等器官。长期适应包括静息心率降低、每搏输出量增加和心肌肥大。
| Component | Function |
| Arteries | Carry blood away from the heart under high pressure |
| Veins | Return blood to the heart, contain valves to prevent backflow |
| Capillaries | Site of gas and nutrient exchange with tissues |
Cardiac Output (Q) = Heart Rate × Stroke Volume
心输出量 = 心率 × 每搏输出量
4. Respiratory System and Gas Exchange | 呼吸系统与气体交换
The respiratory system brings oxygen into the body and removes carbon dioxide. Air travels through the nose/mouth, trachea, bronchi and bronchioles before reaching the alveoli. Gas exchange occurs at the alveoli, where oxygen diffuses into the blood and carbon dioxide diffuses out. Key measurements include tidal volume (air per breath), vital capacity (maximum air expelled after maximum inhalation) and breathing frequency. During exercise, tidal volume and breathing rate increase to meet higher oxygen demand. The diaphragm and intercostal muscles are the main breathing muscles.
呼吸系统将氧气带入体内并排出二氧化碳。空气经过鼻/口、气管、支气管和细支气管，最终到达肺泡。气体交换在肺泡进行，氧气扩散入血，二氧化碳扩散出。关键指标包括潮气量（每次呼吸的气量）、肺活量（最大吸气后最大呼出的气量）和呼吸频率。运动时，潮气量和呼吸频率增加以满足更高的氧气需求。膈肌和肋间肌是主要呼吸肌。
- Alveoli features: large surface area, thin walls, rich blood supply – ideal for diffusion.
- 肺泡特征：表面积大、壁薄、血供丰富 – 非常适合扩散。
- Mechanics of breathing: inspiration – diaphragm contracts and flattens, external intercostals lift ribs; expiration – passive at rest, aided by muscle relaxation.
- 呼吸机制：吸气 – 膈肌收缩下降，外肋间肌上提肋骨；呼气 – 静息时被动，由肌肉放松辅助。
- Oxygen debt: temporary oxygen shortage after intense exercise, repaid by heavy breathing.
- 氧债：剧烈运动后暂时的氧缺乏，通过大口呼吸偿还。
5. Movement Analysis: Levers and Planes | 动作分析：杠杆与运动轴面
Understanding levers helps explain how the human body generates force. There are three classes of levers. First-class levers have the fulcrum between effort and load (e.g., neck extension). Second-class levers have the load between fulcrum and effort (e.g., tip-toe standing). Third-class levers have the effort between fulcrum and load – most common in the body, such as a bicep curl. Performance can be analysed in terms of planes (sagittal, frontal, transverse) and axes (frontal, sagittal, longitudinal). Most sporting movements involve a combination of planes and axes.
理解杠杆有助于解释人体如何产生力量。杠杆分为三类。第一类杠杆支点在力与负荷之间（如颈部后伸）。第二类杠杆负荷在支点与力之间（如踮脚站立）。第三类杠杆力在支点与负荷之间 – 在人体中最常见，如肱二头肌弯举。可以通过运动平面（矢状面、额状面、水平面）和轴（额状轴、矢状轴、垂直轴）来分析动作。大多数体育动作涉及平面和轴的组合。
3rd class lever: Fulcrum – Effort – Load (e.g., elbow)
第三类杠杆：支点 – 力 – 负荷（如肘关节）
6. Components of Health-Related Fitness | 健康相关体能要素
Health-related fitness components underpin overall wellbeing and are essential for everyday life. They include cardiovascular endurance (stamina), muscular strength, muscular endurance, flexibility and body composition. Each component can be tested using specific fitness tests: Cooper run or Multi-stage fitness test for cardiovascular endurance; hand grip dynamometer for strength; sit-and-reach test for flexibility; skinfold callipers for body fat percentage. Different sports place different demands on these components.
健康相关体能要素是整体健康的基础，对日常生活至关重要。它们包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。每个要素都可以通过专门的体能测试来测量：库珀跑或多阶段体能测试测心血管耐力；握力计测力量；坐位体前屈测柔韧性；皮褶卡尺测体脂百分比。不同运动对这些要素有不同要求。
| Component | Definition | Typical Test |
| Cardiovascular Endurance | Ability of heart and lungs to deliver oxygen over time | 12-minute Cooper run |
| Muscular Strength | Max force a muscle can exert in one contraction | Hand grip dynamometer |
| Muscular Endurance | Ability to repeat contractions without fatigue | Press-up / sit-up test |
| Flexibility | Range of movement around a joint | Sit-and-reach test |
7. Components of Skill-Related Fitness | 技能相关体能要素
Skill-related fitness components enhance athletic performance and are more sport-specific. They include agility, balance, coordination, power, reaction time and speed. Agility is the ability to change direction quickly; balance is maintaining equilibrium (static or dynamic); coordination is using senses together with body parts smoothly; power is combining strength and speed; reaction time is the time taken to respond to a stimulus; speed is the rate of covering distance. Practitioners use tests like the Illinois agility run, vertical jump test, stick drop test and 30-metre sprint.
技能相关体能要素提升运动表现，更具专项性。它们包括灵敏性、平衡、协调性、爆发力、反应时间和速度。灵敏性是快速改变方向的能力；平衡是保持稳定（静态或动态）；协调性是感觉与身体部位的流畅配合；爆发力是力量与速度的结合；反应时间是对刺激作出反应所需的时间；速度是覆盖距离的速率。常用的测试有伊利诺伊灵敏跑、纵跳测试、直尺坠落测试和30米冲刺。
- Power = Strength × Speed; essential for jumping, throwing, sprint starts.
- 爆发力 = 力量 × 速度；对跳跃、投掷、起跑至关重要。
- Reaction time can be improved with practice but has a genetic component.
- 反应时间可通过练习改善，但有遗传因素。
- Balance is important in gymnastics, dance and martial arts.
- 平衡在体操、舞蹈和武术中很重要。
8. Principles of Training and Goal Setting | 训练原则与目标设定
Effective training programmes follow the SPORRT principles: Specificity, Progression, Overload, Reversibility, Rest and Recovery, and Tedium (variation). Overload can be manipulated using the FITT formula: Frequency, Intensity, Time and Type. Setting SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound) helps athletes maintain motivation and monitor progress. Understanding these principles allows Year 10 students to design their own personal exercise programmes (PEP) for the coursework component.
有效的训练计划遵循SPORRT原则：专项性、渐进性、超负荷、可逆性、休息与恢复以及趣味性（变化）。超负荷可以通过FITT公式来操作：频率、强度、时间和类型。设定SMART目标（具体的、可衡量的、可实现的、相关的、有时限的）有助于运动员保持动力和监控进展。理解这些原则能让10年级学生为课程作业设计个人运动计划（PEP）。
FITT: Frequency, Intensity, Time, Type
FITT：频率、强度、时间、类型
| Principle | Meaning |
| Specificity | Training matches sport/energy system demands |
| Progression | Gradually increasing difficulty to keep improving |
| Reversibility | Fitness gains are lost when training stops |
9. Methods of Training | 训练方法
There is a variety of training methods, each suited to developing specific fitness components. Continuous training targets cardiovascular endurance with steady, prolonged exercise (e.g., jogging). Fartlek training mixes intensity with speed play. Interval training alternates work and rest periods to develop speed or anaerobic capacity. Circuit training uses stations to combine different exercises, often for muscular endurance. Weight training builds strength and power; plyometric training develops explosive power; and flexibility training (static, ballistic, PNF) improves range of motion. Students must know how to link the method to the component of fitness and sport.
训练方法多种多样，每种适合发展特定的体能要素。持续训练通过稳定、长时间的运动（如慢跑）提高心血管耐力。法特莱克训练将不同强度与速度游戏结合。间歇训练交替工作和休息时段，发展速度或无氧能力。循环训练利用站点组合不同练习，常用于肌肉耐力。重量训练增强力量和爆发力；增强式训练发展爆发力；柔韧性训练（静态、弹震、PNF）改善活动范围。学生必须知道如何将方法与体能要素及运动项目联系起来。
- Interval training: short bursts at high intensity with recovery, e.g., sprint 30s, rest 60s.
- 间歇训练：短时间高强度爆发配合恢复，例如冲刺30秒，休息60秒。
- Plyometrics: bounding, hopping, depth jumps – ideal for basketball and volleyball.
- 增强式训练：缓冲跳、单足跳、深跳 – 适合篮球和排球。
- Weight training: high reps low weight for muscular endurance; low reps high weight for strength.
- 重量训练：高次数低重量增强肌肉耐力；低次数高重量增强力量。
10. Nutrition and Hydration for Performance | 运动营养与水分补充
Proper nutrition provides energy, repairs tissue and supports overall health. Macronutrients are carbohydrates (main fuel for high intensity), fats (fuel for low intensity and insulation) and proteins (growth and repair). Micronutrients – vitamins and minerals – are needed in smaller amounts. Hydration is critical; water regulates temperature and transports nutrients. Dehydration can cause fatigue, cramp and impaired concentration. Athletes should plan meals around training, with pre-exercise snacks rich in slow-release carbs and post-exercise meals including protein for recovery.
合理的营养提供能量、修复组织并支持整体健康。宏量营养素包括碳水化合物（高强度运动的主要燃料）、脂肪（低强度运动和保暖）和蛋白质（生长与修复）。微量营养素 – 维生素和矿物质 – 需要量较小。水分补充至关重要；水调节体温并运输营养。脱水会导致疲劳、抽筋和注意力下降。运动员应围绕训练安排饮食，训练前吃富含慢释碳水化合物的零食，训练后补充含蛋白质的餐食以促进恢复。
- Carbohydrate loading: used by endurance athletes to maximise glycogen stores.
- 糖原负荷法：耐力运动员用来最大化糖原储备。
- Sports drinks: isotonic for rapid rehydration, hypotonic for quick water uptake, hypertonic for energy refuelling.
- 运动饮料：等渗饮料快速补水，低渗饮料迅速吸收水分，高渗饮料补充能量。
- Timing: meal 2–3 hours before competition; light snack 30–60 min before.
- 时间安排：赛前2-3小时进餐；赛前30-60分钟吃易消化零食。
11. Injury Prevention and Safety in Sport | 运动损伤预防与安全
Injury prevention starts with proper warm-up (pulse-raising, stretching, skill rehearsal) and cool-down (gentle exercise, stretching). Using correct technique, appropriate clothing, protective equipment and maintaining safety rules reduce injury risk. Common soft tissue injuries include strains (muscle/tendon) and sprains (ligament), treated with RICE (Rest, Ice, Compression, Elevation). Understand the causes of fractures, dislocations and concussion. Training programmes that balance intensity and rest help avoid overuse injuries such as shin splints and tennis elbow.
损伤预防从正确的热身（提升心率、拉伸、技能演练）和放松活动（轻度运动、拉伸）开始。使用正确技术、合适服装、保护装备并遵守安全规则可降低受伤风险。常见的软组织损伤包括肌肉/肌腱拉伤和韧带扭伤，处理遵循RICE原则（休息、冰敷、加压、抬高）。了解骨折、脱臼和脑震荡的成因。平衡强度与休息的训练计划有助于避免胫骨疲劳性骨膜炎和网球肘等过度使用损伤。
- Warm-up stages: pulse raiser, mobility/stretching, dynamic movements, skill rehearsal.
- 热身阶段：提升心率、活动度/拉伸、动态活动、技能演练。
- Protective equipment: shin pads in football, gum shields in rugby, helmets in cycling.
- 保护装备：足球中的护腿板、橄榄球中的护齿、自行车运动中的头盔。
- RICE: essential immediate response; reduces swelling and pain.
- RICE原则：关键的即时处理；减少肿胀和疼痛。
12. Sport Psychology: Classification of Skills and Feedback | 运动心理学：技能分类与反馈
Skills can be classified along continua: open-closed, basic-complex, self-paced-externally paced, gross-fine. Open skills are affected by the environment (e.g., a pass in football), while closed skills are stable and predictable (e.g., a golf swing). Information processing involves input, decision making, output and feedback. Feedback types include intrinsic (from within the performer), extrinsic (from coach/video), knowledge of results, knowledge of performance, terminal and concurrent. Effective coaches use appropriate feedback to guide learning and motivate athletes.
技能可以按连续体分类：开放式-闭合式、基础-复杂、自主节奏-外部节奏、粗大-精细。开放式技能受环境影响（如足球传球），闭合式技能环境稳定可预测（如高尔夫挥杆）。信息加工包括输入、决策、输出和反馈。反馈类型有内在反馈（来自运动员自身）、外在反馈（来自教练/视频）、结果知晓、表现知晓、末端反馈和同步反馈。高效的教练运用恰当的反馈来指导学习并激励运动员。
- Open skill: basketball dribbling in a game; closed skill: a free throw with no defender.
- 开放式技能：比赛中的篮球运球；闭合式技能：无防守下的罚球。
- Intrinsic feedback: a gymnast feeling a wobble during a handstand; extrinsic: a coach saying 'straighten your legs'.
- 内在反馈：体操运动员倒立时感到晃动；外在反馈：教练说‘把腿伸直’。
- Concurrent feedback is given during performance; terminal feedback is given after.
- 同步反馈在表现过程中给出；末端反馈在表现结束后给出。
