1. The Skeletal System | 骨骼系统
The skeletal system provides structural support, protects vital organs, enables movement by serving as levers, stores minerals and produces blood cells. The human skeleton is divided into the axial skeleton (skull, vertebral column, rib cage) and the appendicular skeleton (limbs, pectoral and pelvic girdles). Bones are classified by shape into long bones (femur), short bones (carpals), flat bones (sternum), irregular bones (vertebrae) and sesamoid bones (patella).
骨骼系统提供结构支撑，保护重要器官，作为杠杆实现运动，储存矿物质并生成血细胞。人体骨骼分为中轴骨（颅骨、脊柱、胸廓）和附肢骨（四肢、肩带和骨盆带）。骨骼按形状分为长骨（股骨）、短骨（腕骨）、扁骨（胸骨）、不规则骨（椎骨）和籽骨（髌骨）。
Joints are the meeting points of two or more bones. Synovial joints, such as the ball-and-socket (hip), hinge (knee), pivot (neck) and gliding (wrist) joints, allow a range of movements including flexion, extension, abduction, adduction, rotation and circumduction. The structure of a synovial joint includes articular cartilage, synovial membrane, synovial fluid, ligaments and tendons to ensure smooth and stable movement.
关节是两块或多块骨骼的连接处。滑膜关节如球窝关节（髋）、屈戌关节（膝）、车轴关节（颈）和滑动关节（腕），允许屈曲、伸展、外展、内收、旋转和环转等运动。滑膜关节的结构包括关节软骨、滑膜、滑液、韧带和肌腱，以保证运动平稳且稳定。
| Joint Type 关节类型 | Movement 运动 | Example 例子 |
|---|---|---|
| Ball-and-socket 球窝 | Flexion, extension, abduction, adduction, rotation, circumduction | Hip, shoulder |
| Hinge 屈戌 | Flexion, extension only | Knee, elbow |
| Pivot 车轴 | Rotation | Neck (atlas-axis) |
| Gliding 滑动 | Slight gliding movements | Carpals, tarsals |
2. The Muscular System | 肌肉系统
There are three types of muscle tissue: skeletal (voluntary, attached to bones), smooth (involuntary, walls of internal organs) and cardiac (involuntary, heart). Skeletal muscles work in antagonistic pairs such as biceps and triceps; when one contracts (agonist), the other relaxes (antagonist) to produce coordinated movement.
肌肉组织分为三类：骨骼肌（随意肌，附着于骨）、平滑肌（不随意肌，内脏壁）和心肌（不随意肌，心脏）。骨骼肌以拮抗对的形式工作，例如肱二头肌和肱三头肌；当一块收缩（主动肌），另一块放松（拮抗肌），从而产生协调运动。
Muscle contraction is explained by the sliding filament theory: myosin heads bind to actin filaments, pull them inward and shorten the sarcomere. Contraction types include isotonic (concentric – muscle shortens, eccentric – muscle lengthens under tension) and isometric (length remains constant). Fast-twitch (type II) fibres are suited for explosive, anaerobic activities, while slow-twitch (type I) fibres are endurance-oriented and aerobic.
肌肉收缩可通过肌丝滑动学说解释：肌球蛋白头与肌动蛋白丝结合，将其向内拉，导致肌节缩短。收缩类型包括等张收缩（向心——肌肉缩短，离心——肌肉在张力下拉长）和等长收缩（长度不变）。快肌纤维（II型）适合爆发性无氧运动，慢肌纤维（I型）偏向耐力有氧活动。
3. The Respiratory System | 呼吸系统
During exercise, the respiratory system increases oxygen intake and carbon dioxide removal. Air travels through the nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles to reach the alveoli, where gaseous exchange occurs by diffusion. The diaphragm and intercostal muscles change thoracic volume to drive inspiration and expiration.
运动时，呼吸系统增加摄氧量并排出二氧化碳。空气经鼻腔、咽、喉、气管、支气管和细支气管进入肺泡，在此处通过扩散进行气体交换。膈肌和肋间肌改变胸腔容积，驱动吸气和呼气。
Key lung volumes measured on a spirometer trace include tidal volume (air per breath at rest), inspiratory reserve volume, expiratory reserve volume, residual volume and vital capacity. During exercise, tidal volume and breathing rate increase to meet oxygen demand. VO₂ max, the maximum volume of oxygen used per minute per kilogram of body mass, is a key indicator of aerobic endurance.
肺活量计曲线测量的关键肺容积包括潮气量（安静时每次呼吸的气量）、补吸气量、补呼气量、残气量和肺活量。运动时潮气量和呼吸频率增加以满足需氧量。VO₂ ₘₐₓ 即每分钟每千克体重最大摄氧量，是有氧耐力的重要指标。
Minute Ventilation (VE) = Tidal Volume (TV) × Breathing Rate (f)
每分钟通气量 = 潮气量 × 呼吸频率
4. The Circulatory System | 循环系统
The circulatory system consists of the heart, blood vessels and blood. The heart has four chambers: right atrium, right ventricle, left atrium and left ventricle. Deoxygenated blood flows to the lungs via the pulmonary artery; oxygenated blood returns to the left atrium and is pumped to the body via the aorta.
循环系统由心脏、血管和血液组成。心脏有四个腔室：右心房、右心室、左心房和左心室。缺氧血经肺动脉流向肺部；富氧血返回左心房并通过主动脉泵往全身。
Cardiac output, the amount of blood pumped by the heart per minute, is determined by heart rate and stroke volume. During exercise, both increase to deliver more oxygen to working muscles. Blood pressure is expressed as systolic over diastolic pressure (e.g. 120/80 mmHg). Vasodilation and vasoconstriction redistribute blood flow to active areas.
心输出量即心脏每分钟泵出的血量，由心率和每搏输出量决定。运动时二者均增加，为工作肌肉输送更多氧气。血压表示为收缩压/舒张压（例如120/80 mmHg）。血管舒张和收缩可重新分配血流至活跃区域。
Cardiac Output (Q) = Heart Rate (HR) × Stroke Volume (SV)
心输出量 = 心率 × 每搏输出量
5. Health, Fitness and Training | 健康、体能和训练
Health is a state of complete physical, mental and social well-being; fitness is the ability to meet the demands of the environment. Health-related fitness components include cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition. Skill-related components are agility, balance, coordination, power, reaction time and speed.
健康是身体、心理和社会适应方面的完好状态；体适能是满足环境需求的能力。健康相关体适能包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。技能相关体适能包括敏捷性、平衡、协调、爆发力、反应时间和速度。
Training principles are summarised by SPOR: Specificity, Progression, Overload, Reversibility. The FITT principle (Frequency, Intensity, Time, Type) helps design training programmes. Common training methods include continuous, interval, fartlek, circuit, weight, plyometric and flexibility training. Fitness testing with tests such as the multi-stage fitness test, Cooper 12-minute run, handgrip dynamometer and sit-and-reach provides baseline data and tracks progress.
训练原则可用SPOR概括：专项性、渐进性、超负荷和可逆性。FITT原则（频率、强度、时间、类型）有助于设计训练计划。常见训练方法包括持续训练、间歇训练、法特莱克、循环训练、负重训练、超等长训练和柔韧训练。通过多阶段体能测试、库珀12分钟跑、握力计和坐位体前屈等测试进行体适能测评，可获取基线数据并跟踪进步。
6. Skill Acquisition and Psychology | 技能习得与心理学
Skills can be classified on continua: open–closed (environmental stability), gross–fine (muscular involvement), discrete–serial–continuous (beginning and end), self-paced–externally paced (timing control). A beginner typically progresses through the cognitive, associative and autonomous stages of learning. Feedback types include intrinsic, extrinsic, knowledge of results and knowledge of performance.
技能可按连续统一体分类：开放–闭合（环境稳定性）、粗大–精细（肌肉参与）、离散–序列–连续（起点和终点）、自定节奏–外部节奏（时机控制）。初学者通常经历认知、联结和自动化学习阶段。反馈类型包括内在反馈、外在反馈、结果认知和表现认知。
In sport psychology, arousal and anxiety influence performance. The inverted-U theory suggests that optimal performance occurs at a moderate level of arousal. Drive theory predicts a linear relationship, but only for well-learned tasks or highly skilled performers. Intrinsic motivation comes from within, while extrinsic motivation relies on external rewards; both can affect persistence and performance.
在运动心理学中，唤醒和焦虑影响运动表现。倒U型理论认为，适中的唤醒水平下表现最佳。驱力理论预测线性关系，但仅适用于熟练任务或高水平运动员。内在动机源于自身，外在动机依赖外部奖励；二者均可影响坚持度和运动表现。
7. Social and Cultural Influences | 社会文化影响
Participation in physical activity is influenced by factors such as age, gender, ethnicity, socio-economic status, family and peer support, media coverage and access to facilities. Gender stereotyping can discourage participation in certain sports, while positive role models and inclusive policies can boost engagement. The media plays a dual role by promoting sport and shaping public perception, but can also reinforce inequality.
参与体育活动受年龄、性别、种族、社会经济地位、家庭和同伴支持、媒体报道以及设施可及性等因素影响。性别刻板印象可能抑制某些运动的参与，而正面榜样和包容性政策可提升参与度。媒体通过推广运动并塑造公众认知发挥双重作用，但也可能强化不平等。
Sponsorship and commercialisation bring financial benefits and increase exposure, yet they may place excessive pressure on performers and shift focus from participation to profit. Ethics in sport covers sportsmanship, gamesmanship, deviance (e.g. doping, violence) and the importance of fair play. Organisations such as WADA work to combat drug misuse and protect the integrity of sport.
赞助和商业化带来经济收益并增加曝光度，但也可能给运动员带来过大压力，并将重心从参与转向盈利。体育伦理涵盖运动员精神、投机取巧行为、越轨行为（如兴奋剂、暴力）以及公平竞争的重要性。世界反兴奋剂机构等组织致力于打击药物滥用，维护体育诚信。
8. Nutrition and Energy Systems | 营养与能量系统
A balanced diet includes macronutrients (carbohydrates, fats, proteins) and micronutrients (vitamins, minerals). Carbohydrates are the primary fuel for high-intensity exercise; fats provide energy during low-intensity, prolonged activity; protein is essential for muscle repair and growth. Hydration is critical, as even mild dehydration impairs performance.
均衡饮食包括宏量营养素（碳水化合物、脂肪、蛋白质）和微量营养素（维生素、矿物质）。碳水化合物是高强度运动的主要燃料；脂肪在低强度长时间活动中供能；蛋白质对肌肉修复和生长至关重要。水合作用非常关键，即使轻度脱水也会损害运动表现。
The body uses three energy systems to resynthesise ATP: the ATP-PC system (anaerobic, 8–10 seconds of maximal work), the anaerobic glycolytic system (lactic acid system, up to about 60–90 seconds) and the aerobic system (with oxygen, for prolonged activity). The type, intensity and duration of exercise dictate which system predominates. The concept of the lactate threshold marks the point at which lactate accumulates faster than it can be removed.
人体使用三种能量系统再合成ATP：ATP-CP系统（无氧，供8–10秒最大强度运动）、无氧糖酵解系统（乳酸系统，约60–90秒）和有氧系统（有氧，长时间运动）。运动的类型、强度和时长决定了哪种系统占主导。乳酸阈指乳酸积累速度超过清除速度的临界点。
9. Prevention of Injury | 运动损伤预防
A proper warm-up increases muscle temperature, blood flow and joint mobility, reducing the risk of injury. A cool-down aids removal of metabolic by-products and prevents blood pooling. Common sports injuries include strains (muscle/tendon), sprains (ligaments), fractures, dislocations, and overuse injuries such as shin splints and tennis elbow.
适当的热身能提高肌肉温度、血流和关节灵活性，降低受伤风险。整理活动有助于清除代谢副产物，防止血液淤积。常见运动损伤包括拉伤（肌肉/肌腱）、扭伤（韧带）、骨折、脱位以及过劳性损伤，如外胫夹和网球肘。
Immediate care for soft-tissue injuries follows the RICE protocol: Rest, Ice, Compression, Elevation. Injury prevention strategies involve risk assessment, use of protective equipment, appropriate training load and technique correction. Understanding intrinsic (age, previous injury) and extrinsic (surface, weather) risk factors helps tailor prevention measures.
软组织损伤的即时处理遵循RICE原则：休息、冰敷、加压包扎和抬高患肢。损伤预防策略包括风险评估、使用防护装备、合理安排训练负荷和纠正技术。了解内在风险因素（年龄、旧伤）和外在风险因素（场地、天气）有助于制定针对性预防措施。
10. Technology in Sport | 体育科技
Technological advances have transformed sport through improved equipment, performance analysis and injury management. Examples include carbon-fibre running blades, heart-rate monitors, GPS tracking, video replay systems and wearable sensors. Motion capture software provides detailed biomechanical feedback, while data analytics informs tactical decisions.
技术进步通过改良装备、运动表现分析和损伤管理改变了体育运动。例如碳纤维跑步义肢、心率监测器、GPS追踪、视频回放系统和可穿戴传感器。动作捕捉软件提供详细的生物力学反馈，数据分析则为战术决策提供依据。
Technology can also raise ethical questions about fairness, such as the use of full-body swimsuits or prosthetic limbs that may give an advantage. Drug testing technology continues to evolve to detect banned substances. The balance between innovation and maintaining a level playing field remains a key discussion point in modern sport.
科技也会引发关于公平性的伦理问题，例如可能带来优势的全身泳衣或义肢的使用。药物检测技术不断进步以检测违禁物质。创新与维持公平竞赛环境之间的平衡仍是现代体育中的关键议题。
