1. Skeletal System: Structure and Functions | 骨骼系统：结构与功能
The human skeleton provides shape, support, protection, movement, mineral storage and blood cell production. Key bones include the cranium, clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges, ribs, sternum, vertebral column, pelvis, femur, patella, tibia, fibula, tarsals and metatarsals. Long bones act as levers, flat bones protect vital organs, and irregular bones provide stability.
人体骨骼具有支撑、保护、运动、矿物质储存和造血等功能。关键骨骼有颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、腕骨、掌骨、指骨、肋骨、胸骨、脊柱、骨盆、股骨、髌骨、胫骨、腓骨、跗骨和跖骨。长骨作为杠杆，扁平骨保护器官，不规则骨提供稳定支撑。
2. Joints and Movement Types | 关节与运动类型
Synovial joints enable a wide range of motion. Ball‑and‑socket joints (shoulder, hip) allow flexion, extension, abduction, adduction, rotation and circumduction. Hinge joints (elbow, knee) permit flexion and extension. Pivot joints enable rotation, while gliding joints slide over each other. Movements such as plantar flexion and dorsiflexion occur at the ankle.
滑膜关节产生大幅运动。球窝关节（肩、髋）可做屈、伸、外展、内收、旋转和环转；铰链关节（肘、膝）只做屈伸；枢轴关节允许旋转；滑动关节相对滑移。踝部的跖屈和背屈也是重要动作类型。
3. Muscular System and Antagonistic Pairs | 肌肉系统与拮抗肌对
Major skeletal muscles include the deltoid, biceps, triceps, pectorals, latissimus dorsi, abdominals, hip flexors, gluteals, quadriceps, hamstrings and gastrocnemius. Muscles often work in antagonistic pairs: the agonist contracts while the antagonist relaxes. For example, during elbow flexion the biceps is the agonist and the triceps is the antagonist. Fixators stabilise the origin to aid movement.
主要骨骼肌有三角肌、肱二头肌、肱三头肌、胸肌、背阔肌、腹肌、髋屈肌、臀肌、股四头肌、腘绳肌和腓肠肌。肌肉常成对拮抗工作：主动肌收缩时拮抗肌放松。例如屈肘时肱二头肌为主动肌，肱三头肌为拮抗肌。固定肌稳定起点以协助完成动作。
4. Cardiovascular System during Exercise | 运动时的心血管系统
The cardiovascular system consists of the heart, blood and blood vessels. During exercise, heart rate, stroke volume and cardiac output increase to deliver more oxygen to working muscles. The double circulatory system (systemic and pulmonary) ensures efficient gas exchange. Long‑term adaptations include a lower resting heart rate, increased stroke volume and faster recovery.
心血管系统由心脏、血液和血管组成。运动时心率、每搏输出量和心输出量增加，向肌肉供氧。双循环（体循环与肺循环）确保高效气体交换。长期适应包括安静心率降低、每搏输出量增加和恢复速度加快。
5. Respiratory System and Gas Exchange | 呼吸系统与气体交换
Air travels through the nose, pharynx, larynx, trachea, bronchi and bronchioles to reach the alveoli, where gaseous exchange occurs. During exercise, tidal volume, breathing frequency and minute ventilation rise. Oxygen diffuses into the capillaries, and carbon dioxide is removed. Vital capacity is the maximum volume of air that can be exhaled after a maximal inhalation.
空气经鼻、咽、喉、气管、支气管和细支气管到达肺泡，于此完成气体交换。运动时潮气量、呼吸频率和每分通气量增加。氧气弥散入毛细血管，二氧化碳被排出。肺活量是最大吸气后所能呼出的最大气量。
6. Components of Fitness: Health‑related | 体适能组成：健康相关
Cardiovascular endurance is the ability of the heart and lungs to supply oxygen over a sustained period; it is tested by the Cooper Run or Multi‑stage Fitness Test. Muscular endurance is the repeated contraction of a muscle group without fatigue (e.g. sit‑up test). Strength is maximal force exerted (handgrip dynamometer). Flexibility is the range of motion around a joint (sit and reach test). Body composition refers to the percentage of fat, muscle and bone (skinfold callipers).
心血管耐力是心肺长时间供氧的能力，可用库珀跑或多级折返跑测试；肌肉耐力是肌群反复收缩而无疲劳的能力（如仰卧起坐测试）；力量指最大力（握力计测试）；柔韧性是关节活动范围（坐位体前屈测试）；身体成分指脂肪、肌肉与骨质的百分比（皮褶卡尺测量）。
7. Components of Fitness: Skill‑related | 体适能组成：技能相关
Agility is the ability to change direction at speed (Illinois Agility Test). Balance is maintaining equilibrium while stationary or moving (stork stand). Coordination is using two or more body parts smoothly (wall toss test). Power combines strength and speed (vertical jump test). Reaction time is the time taken to respond to a stimulus (ruler drop test). Speed is the rate of covering distance (30 m sprint test).
灵敏是快速改变方向的能力（伊利诺伊敏捷测试）；平衡是静止或移动中保持稳定的能力（鹤立测试）；协调是顺畅运用两个以上身体部位（墙壁投掷球测试）；爆发力是速度与力量的结合（垂直纵跳测试）；反应时是对刺激做出应答的时间（落尺测试）；速度是位移速率（30 米冲刺测试）。
8. Principles of Training (SPORT / FITT) | 训练原则
Training must follow key principles: Specificity (matching training to the activity), Progression (gradually increasing workload), Overload (working beyond normal levels using the FITT formula), Reversibility (fitness declines when training stops) and Tedium (avoiding boredom through variety). Overload is achieved by manipulating Frequency, Intensity, Time and Type of exercise.
训练须遵循原则：针对性（训练与专项匹配）、渐进性（逐步增加负荷）、超负荷（运用 FITT 公式超越常态训练）、可逆性（停训后体能消退）和趣味性（以多样方式避免枯燥）。超负荷可通过调节频率、强度、时间和运动类型实现。
9. Methods of Training | 训练方法
Continuous training develops cardiovascular endurance with steady, moderate‑intensity effort (e.g. long‑distance running). Interval training alternates high‑intensity work with recovery periods, improving speed and anaerobic capacity. Circuit training uses different exercise stations to build muscular endurance and strength. Weight training increases strength and power. Plyometrics uses explosive movements to develop power; HIIT delivers intense bursts followed by short rests for cardiovascular and metabolic gains.
持续训练以稳定中低强度提高心血管耐力（如长跑）；间歇训练在高强度与恢复期之间交替，改善速度与无氧能力；循环训练利用不同站点增强肌肉耐力与力量；负重训练提升力量与爆发力；增强式训练通过爆发动作发展爆发力；高强度间歇训练（HIIT）以爆发式运动加短暂休息获得心血管与代谢收益。
10. Injury Prevention, Warm‑up and Cool‑down | 伤病预防与热身整理
A structured warm‑up raises heart rate, mobilises joints and stretches muscles, reducing injury risk. The cool‑down gradually lowers heart rate and disperses lactic acid. Injury prevention strategies include using correct equipment, following rules, applying proper technique and balancing competition with rest. The RICE method (Rest, Ice, Compression, Elevation) is used for immediate soft tissue injury management.
合理热身可提升心率、活动关节与拉伸肌肉，降低受伤风险。整理活动可平缓心率、促进乳酸清除。伤病预防措施包括使用恰当器材、遵守规则、应用正确技术与合理休息。RICE 原则（休息、冰敷、加压、抬高）用于软组织损伤的即时处理。
11. Sport Psychology: Skill Classification and Feedback | 运动心理学：技能分类与反馈
Skills are classified on continua: open–closed (affected by the environment), self‑paced–externally paced (control over timing), gross–fine (large or small muscle groups), basic–complex (difficulty). Feedback can be intrinsic (from within the performer) or extrinsic (from coach/video). Knowledge of results focuses on outcome, while knowledge of performance concerns the process. Effective feedback is specific, immediate and constructive.
技能可按连续体分类：开放–闭锁（受环境影响）、自定节奏–外部定节奏（对时机的控制）、粗大–精细（大小肌群参与）、基础–复杂（难度）。反馈可分为内在反馈（自身感觉）与外在反馈（教练/视频）。结果反馈重结果，绩效反馈重过程。有效反馈应当具体、及时且具有建设性。
12. Socio‑cultural Influences on Participation | 社会文化对参与度的影响
Participation in physical activity is influenced by factors such as gender, age, socio‑economic status, ethnicity, disability, access to facilities, media representation and role models. Organisations promote inclusion through targeted campaigns, modified equipment and community programmes. Understanding these barriers helps devise strategies to increase lifelong involvement in sport and exercise.
参与体育活动受性别、年龄、社会经济地位、种族、残疾、设施可达性、媒体呈现与榜样等因素影响。各机构通过定向宣传、改良器材和社区计划促进包容性。认识这些障碍有助于制定促进终身参与体育运动的策略。
