1. The Skeletal System | 骨骼系统
The human skeleton gives the body its shape, supports soft tissues and protects vital organs. In sport, the skeleton acts as a system of levers that muscles pull on to create movement. The main bones you need to know include the cranium, clavicle, scapula, humerus, radius, ulna, vertebrae, pelvis, femur, patella, tibia and fibula. Learning the names and locations of these bones is the first step towards analysing movement in activities like throwing, kicking and sprinting.
人体骨骼不仅支撑起身体轮廓，保护内脏，更是运动的杠杆系统。你需要熟记的关键骨块包括颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、脊椎、骨盆、股骨、髌骨、胫骨和腓骨。掌握这些骨骼的名称与位置，就能在分析投掷、踢球、冲刺等动作时有据可依。
2. Functions of the Skeleton | 骨骼的功能
Beyond providing shape, the skeleton has five key functions: support, protection, movement, mineral storage and blood cell production. Long bones such as the femur store calcium and phosphorus, while the marrow inside some bones is where red and white blood cells are made. During a tackle in rugby or a fall in gymnastics, the ribcage and skull shield the heart, lungs and brain. Recognising these roles helps you understand why strong, healthy bones matter for both performance and long-term wellbeing.
除了塑形，骨骼还承担着支撑、保护、运动、矿物质储存与造血五大功能。长骨如股骨储存钙和磷，骨髓则负责制造红血球与白血球。橄榄球中的擒抱或体操落地时，胸腔和颅骨会保护心脏、肺部与大脑。弄清楚这些功能，你就会明白健康的骨骼对运动表现和长期健康同等重要。
3. Types of Bones | 骨骼的类型
Bones are classified by shape into four groups: long bones (e.g. femur, humerus), short bones (e.g. carpals, tarsals), flat bones (e.g. cranium, sternum) and irregular bones (e.g. vertebrae). Long bones act as levers for large movements; flat bones provide broad surfaces for muscle attachment and protection; short bones give stability and shock absorption; irregular bones have specialised shapes for specific jobs, like supporting the spinal cord. Matching bone type to function is a common exam skill.
骨骼按形状分为四类：长骨（如股骨、肱骨）用于大幅度杠杆运动；短骨（如腕骨、跗骨）提供稳定性并吸收冲击；扁骨（如颅骨、胸骨）有大面积供肌肉附着并保护脏器；不规则骨（如脊椎）形状专用于支撑脊髓等特殊任务。把骨类型与其功能配对，是考试中常见的分析思路。
4. The Muscular System | 肌肉系统
Muscles produce force by contracting and pulling on bones, creating movement at joints. The main voluntary muscles to learn are the deltoid, biceps, triceps, pectorals, abdominals, quadriceps, hamstrings, gastrocnemius, latissimus dorsi and gluteals. When a footballer strikes the ball, the quadriceps extend the knee while the hamstrings control the follow-through. Understanding agonist and antagonist pairs will help you analyse any sporting technique.
肌肉收缩产生拉力，牵引骨骼绕关节运动。你需要记住的主要随意肌包括三角肌、肱二头肌、肱三头肌、胸大肌、腹肌、股四头肌、腘绳肌、腓肠肌、背阔肌和臀大肌。足球运动员射门时，股四头肌伸膝，腘绳肌控制随球动作。掌握主动肌与拮抗肌配对，就能分析各种运动技术。
5. Types of Muscles and Their Roles | 肌肉类型及其作用
The body contains three muscle types: cardiac muscle found only in the heart, smooth muscle in the walls of blood vessels and organs, and skeletal muscle attached to bones. Skeletal muscle is under voluntary control and is responsible for all sporting movements. Within a movement, the agonist (prime mover) contracts while the antagonist relaxes. For example, during a bicep curl the biceps is agonist and the triceps is antagonist. Fixator muscles stabilise the origin of the agonist, allowing efficient force transfer.
人体有三种肌肉：仅在心脏的心肌、分布于血管和内脏壁的平滑肌、以及附着在骨骼上的骨骼肌。骨骼肌受意识支配，是体育运动中所有动作的来源。在同一个动作里，主动肌收缩，拮抗肌放松。如弯举哑铃时，肱二头肌为主，肱三头肌为拮抗；固定肌则稳定主动肌起点，使力量传递更高效。
6. The Cardiovascular System | 心血管系统
The cardiovascular system consists of the heart, blood and blood vessels. Its job is to transport oxygen, nutrients and hormones to working muscles, and to remove waste products such as carbon dioxide. The heart is a double pump: the right side sends blood to the lungs, the left side pumps oxygenated blood to the body. During a cross-country run, your heart rate rises to increase cardiac output, ensuring that active leg muscles receive enough oxygen to sustain effort.
心血管系统由心脏、血液和血管组成，负责把氧气、营养和激素送到工作的肌肉，同时带走二氧化碳等代谢废物。心脏是双泵结构——右侧将血送往肺部，左侧将充氧血输往全身。越野跑时，心率上升以增加心输出量，确保腿部肌肉获得足够氧气维持运动。
7. Components of Blood | 血液成分
Blood is made up of four main components: red blood cells, white blood cells, platelets and plasma. Red blood cells contain haemoglobin, which binds oxygen and carries it to tissues. White blood cells fight infection, platelets help clotting after injury, and plasma is the liquid medium that transports dissolved substances and heat. In sport, a richer red blood cell count improves aerobic endurance, a fact that explains why athletes living at altitude can gain a training advantage.
血液主要由红细胞、白细胞、血小板和血浆四种成分组成。红细胞含血红蛋白，负责携带氧气；白细胞参与免疫防御；血小板在损伤后促进凝血；血浆则运输溶解的养分与热量。运动中，红细胞数量丰富意味着更好的有氧耐力，这也是高原训练能带来竞技优势的原因之一。
8. The Respiratory System | 呼吸系统
The respiratory system brings air into the body and exchanges oxygen and carbon dioxide between the lungs and the blood. Air travels through the trachea, bronchi and bronchioles before reaching tiny air sacs called alveoli. Here, oxygen diffuses into capillaries while carbon dioxide moves out to be exhaled. The diaphragm and intercostal muscles work together to change the volume of the chest cavity, pulling air in and pushing it out. Efficient breathing technique is vital in swimming, rowing and distance running.
呼吸系统将空气导入体内，在肺部与血液间完成氧气和二氧化碳的交换。空气经气管、支气管、细支气管进入微小的肺泡。氧气由此弥散入毛细血管，二氧化碳则被呼出。膈肌和肋间肌协同改变胸腔容积，实现吸气和呼气。高效的呼吸技巧对游泳、划船和长跑等项目至关重要。
9. Aerobic and Anaerobic Exercise | 有氧与无氧运动
Aerobic exercise uses oxygen to break down glucose and fat, producing energy slowly but sustainably. Examples include jogging, cycling and dancing. Anaerobic exercise works without oxygen and provides quick bursts of energy for high-intensity activities like sprinting or weightlifting, but produces lactic acid, which leads to muscle fatigue. Knowing the energy pathway you rely on in different sports helps you pace yourself and choose appropriate recovery strategies.
有氧运动利用氧气分解葡萄糖和脂肪，产能量慢但持久，如慢跑、骑行和舞蹈。无氧运动无需氧气，能为短跑、举重等高强度活动提供快速能量，但会产生乳酸，导致肌肉疲劳。看懂不同项目依赖的供能路径，你就能更好地分配体力，并选择合理的恢复手段。
10. Components of Fitness | 体适能要素
Fitness is broken down into health-related and skill-related 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. A gymnast needs great flexibility, balance and power, while a marathon runner relies on cardiovascular endurance and muscular endurance. Being able to link the correct components to specific sports is a fundamental GCSE PE skill.
体适能分为健康相关要素和技能相关要素。健康类包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。技能类则包括敏捷性、平衡、协调性、爆发力、反应时间和速度。体操选手需要出色的柔韧性、平衡和爆发力，马拉松跑者依赖心血管耐力和肌肉耐力。能将正确的体适能要素与运动项目匹配，是GCSE体育的基本功。
11. Principles of Training | 训练原则
To improve fitness safely and effectively, athletes apply the SPOR training principles: Specificity, Progression, Overload, Reversibility and Tedium. Overload can be achieved by manipulating FITT variables—Frequency, Intensity, Time and Type. For instance, a swimmer building endurance might gradually increase the number of laps (time) or reduce rest intervals (intensity). These principles prevent plateaus and injury while maximising adaptation.
运动员运用 SPOR 训练原则来安全高效地提升体适能：针对性、渐进性、超负荷、可逆性和避免单调。超负荷可通过调控 FITT 变量——频率、强度、时间和类型来实现。例如，游泳者增强耐力时可逐步增加圈数（时间）或缩短组间休息（强度）。这些原则可规避瓶颈和伤病，让训练效果最大化。
12. Nutrition and Hydration | 营养与水分补充
A balanced diet supplies the macro- and micronutrients needed for energy, growth and repair. Carbohydrates are the main fuel for exercise; proteins aid muscle repair; fats provide long-term energy and insulation. Vitamins and minerals support everything from bone health (calcium) to oxygen transport (iron). Hydration is equally critical—losing just 2% of body weight through sweat can impair performance. Timing meals and fluids around training sessions is a practical skill that underpins athletic success.
均衡膳食提供运动所需的宏量和微量元素。碳水化合物是运动主燃料，蛋白质修复肌肉，脂肪供给长期能量并保温。维生素和矿物质则从骨健康（钙）到氧气运输（铁）全面支持身体。水分补充同样关键——汗液流失仅体重的2%就足以影响运动表现。根据训练安排合理进餐和补水，是支撑竞技状态的实用能力。
