1. Weekly Schedule for Winter Break | 寒假每周复习计划
Aim for four focused sessions per week, each lasting 45–60 minutes. Monday can be Anatomy & Physiology, Wednesday Physical Training, Friday Movement Analysis, and Sunday a light recap quiz. Keep a revision log to track topics you have mastered and those needing more work.
建议每周安排四次专注的复习时段，每次45–60分钟。周一安排解剖与生理，周三体能训练，周五运动分析，周日进行轻松的回顾测验。制作一份复习日志，标记已掌握的主题以及仍需加强的部分。
Supplement desk study with active recovery: a 20‑minute jog, stretching or a skills circuit. This links theory to practice and keeps your body moving during the holidays.
在书面学习之外，加入积极恢复活动：20分钟慢跑、拉伸或技能循环训练。这既能将理论与运动实践相结合，也能让身体在假期保持活力。
2. Skeletal System Revision | 骨骼系统复习
The skeleton provides support, protection, movement, mineral storage and blood cell production. Bones are classified into long (femur), short (carpals), flat (cranium) and irregular (vertebrae). Joints such as ball‑and‑socket, hinge and pivot allow different ranges of motion with the help of ligaments, tendons and cartilage.
骨骼具有支撑、保护、运动、矿物质储存和造血功能。骨骼分为长骨（股骨）、短骨（腕骨）、扁骨（颅骨）和不规则骨（椎骨）。球窝关节、铰链关节和枢轴关节等在韧带、肌腱和软骨的辅助下实现不同的运动幅度。
| Joint Type 关节类型 | Example 示例 | Movement 运动 |
|---|---|---|
| Ball‑and‑socket 球窝 | Shoulder / hip | Flexion, extension, rotation, abduction |
| Hinge 铰链 | Elbow / knee | Flexion and extension only |
| Pivot 枢轴 | Neck (atlas/axis) | Rotation |
Learn to label major bones on a diagram: cranium, clavicle, scapula, humerus, radius, ulna, ribs, sternum, vertebral column, pelvis, femur, patella, tibia and fibula. For joints, be ready to describe how synovial fluid reduces friction and how cartilage prevents bone‑on‑bone contact.
学会在示意图上标注主要骨骼：颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、肋骨、胸骨、脊柱、骨盆、股骨、髌骨、胫骨和腓骨。针对关节，要能描述滑液如何减少摩擦，以及软骨如何避免骨与骨直接接触。
3. Muscular System and Movement | 肌肉系统与运动
Voluntary muscles produce movement by pulling on bones. Antagonistic pairs work opposite each other: the agonist contracts while the antagonist relaxes. For a bicep curl, the bicep is the agonist and the tricep is the antagonist; for the downward phase, the tricep becomes the agonist.
随意肌通过牵拉骨骼产生运动。拮抗肌对相互配合：主动肌收缩时，拮抗肌放松。以肱二头肌弯举为例，肱二头肌是主动肌，肱三头肌是拮抗肌；在下放阶段，肱三头肌则成为主动肌。
Key muscles to name and locate: deltoid, pectorals, latissimus dorsi, abdominals, quadriceps, hamstrings, gastrocnemius, gluteals, hip flexors and tibialis anterior. Describe the type of contraction: isotonic (concentric shortens, eccentric lengthens) and isometric (length stays the same, e.g. wall sit).
需要命名并定位的关键肌肉：三角肌、胸肌、背阔肌、腹肌、股四头肌、腘绳肌、腓肠肌、臀肌、髋屈肌和胫骨前肌。描述收缩类型：等张收缩（向心收缩时肌肉缩短，离心收缩时拉长）和等长收缩（肌肉长度不变，如靠墙静蹲）。
4. Cardiovascular Fitness | 心血管健康
The cardiovascular system comprises the heart, blood vessels and blood. Oxygenated blood leaves the heart via the aorta and travels through arteries to working muscles. Deoxygenated blood returns through veins, helped by valves. The heart’s chambers—atria and ventricles—contract in a double‑circuit pump (systemic and pulmonary).
心血管系统由心脏、血管和血液组成。含氧血液经由主动脉离开心脏，通过动脉输送到工作肌肉。去氧血液则通过静脉回流，静脉瓣膜起到辅助作用。心脏的腔室——心房和心室——以双循环方式（体循环和肺循环）搏动泵血。
stroke volume (SV). Exercise increases HR and SV, boosting Q to deliver more oxygen. Long‑ daptations include lower resting HR, larger ventricular volume and improved recovery rate.
掌握心率、每搏输出量和心输出量的定义：心输出量（Q）= 心率（HR）× 每搏输出量（SV）。运动使心率和每搏量上升，从而增加心输出量以运输更多氧气。长期适应包括安静心率降低、心室容积增大和恢复速率加快。
5. Respiratory System in Exercise | 运动中的呼吸系统
Air enters through the nose/mouth, passes the pharynx, larynx, trachea, bronchi and bronchioles, and reaches the alveoli where gaseous exchange occurs. Oxygen diffuses into the blood; carbon dioxide diffuses out. The diaphragm and intercostal muscles drive inhalation (contract) and exhalation (relax).
空气通过鼻或口进入，经过咽、喉、气管、支气管和细支气管，抵达发生气体交换的肺泡。氧气扩散进入血液，二氧化碳则扩散排出。膈肌和肋间肌通过收缩（吸气）和放松（呼气）来驱动呼吸。
Tidal volume, minute ventilation and vital capacity describe lung performance. During exercise, breathing rate and depth increase to supply more oxygen and remove excess CO₂. Use spirometer traces to identify these volumes and explain immediate responses versus long‑term adaptations, such as stronger respiratory muscles.
潮气量、每分通气量和肺活量是衡量肺部机能的重要指标。运动时呼吸频率和深度增加，以供应更多氧气并排出多余的二氧化碳。学会通过肺活量计曲线图识别这些容量，并解释即时反应与长期适应，例如呼吸肌变得更强壮。
6. Components of Fitness | 体能要素
Health‑related components include cardiovascular endurance, muscular endurance, strength, flexibility and body composition. Skill‑related components include agility, balance, coordination, power, reaction time and speed. Be ready to match each component to specific sports—e.g. agility for netball, balance for gymnastics, power for long jump.
健康相关体能要素包括心肺耐力、肌耐力、力量、柔韧性和身体成分。技能相关体能要素包括敏捷性、平衡、协调性、爆发力、反应时间和速度。要能将这些要素与具体运动项目联系起来——例如篮网球需要敏捷性，体操需要平衡，跳远需要爆发力。
Fitness tests: the multi‑stage fitness test estimates VO₂max; the sit‑and‑reach test measures flexibility; the handgrip dynamometer measures strength; the 30‑metre sprint tests speed. Know the protocols, advantages and limitations of each test so you can suggest improvements.
体能测试方法：多阶段往返跑测试可估算最大摄氧量；坐位体前屈测试柔韧性；握力计测量力量；30米冲刺测速度。熟记每项测试的操作流程、优点和局限性，以便提出合理的改进建议。
7. Principles of Training | 训练原则
Apply SPORTI: Specificity, Progression, Overload, Reversibility, Tedium, and Individual needs. To achieve overload, manipulate FITT: Frequency, Intensity, Time and Type. For example, to improve muscular endurance use low weight and high reps; for strength, high weight and low reps.
运用 “SPORTI” 原则：专项性、渐进性、超负荷、可逆性、趣味性和个体差异。实现超负荷需调整 FITT 变量：频率、强度、时间和类型。例如，提升肌耐力可采用小重量、多次数；提升最大力量则用大重量、少次数。
Training methods: continuous training develops aerobic endurance; interval training alternates work and rest; circuit training targets multiple fitness components; plyometrics builds explosive power; and weight training develops strength and muscular endurance. Link each method to the relevant component of fitness and athlete profiles.
训练方法：持续训练发展有氧耐力；间歇训练交替进行高强度与休息；循环训练可同时训练多种体能要素；增强式训练培养爆发力；重量训练则提高力量和肌耐力。将每种方法与其对应的体能要素和运动员类型结合起来。
8. Nutrition for Performance | 运动营养
Macronutrients: carbohydrates as the main energy source (stored as glycogen), proteins for growth and repair, and fats for low‑intensity energy and insulation. Micronutrients (vitamins and minerals) support bone health, energy release and muscle function. Hydration is critical; even a 2% loss of body fluid can impair performance.
宏量营养素：碳水化合物是主要能量来源（以糖原形式储存），蛋白质用于生长与组织修复，脂肪提供低强度运动时的能量并起保温作用。微量营养素（维生素和矿物质）则支持骨骼健康、能量释放和肌肉功能。补水也至关重要，体液丢失仅2%就可能削弱运动表现。
Design a meal plan for a competition day: high‑carbohydrate breakfast 3‑4 hours before, a light snack (banana) 1‑2 hours before, and fluids throughout. Post‑exercise, combine protein and carbohydrates to refuel and rebuild. Use the Eatwell Guide to balance food groups for general health.
为比赛日设计膳食方案：赛前3‑4小时高碳水化合物早餐，赛前1‑2小时清淡加餐（香蕉），全天持续补水。运动后，搭配蛋白质与碳水化合物以补充能量和修复组织。参照《平衡膳食指南》均衡搭配食物以维持整体健康。
9. Skill Acquisition and Feedback | 技能习得与反馈
Skills are classified along continua: open–closed (environmental predictability), gross–fine (muscle groups used), self‑paced–externally paced, and discrete–serial–continuous (clear beginning and end). A tennis serve is a closed, gross, self‑paced, discrete skill; dribbling in hockey is open, gross, externally paced and serial.
技能可按不同连续谱分类：开放型‑闭合型（环境可预测性）、粗大型‑精细型（动用肌群）、自定节奏‑外部节奏，以及分立‑序列‑连续型（起止清晰度）。网球发球属于闭合‑粗大‑自定节奏‑分立技能；曲棍球运球则属于开放‑粗大‑外部节奏‑序列技能。
Feedback guides improvement: intrinsic (kinaesthetic feel), extrinsic (coach’s comment), knowledge of performance (technique) and knowledge of results (outcome). Beginners benefit from positive and extrinsic feedback; advanced performers can interpret intrinsic and more detailed feedback. Set SMART goals to stay motivated.
反馈能引导动作改进：内在反馈（本体感觉）、外在反馈（教练点评）、表现知晓（技术评价）和结果知晓（成果信息）。初学者多受益于积极的外在反馈；高水平运动员则能理解内在反馈和更精细的指导。制定SMART目标以保持动力。
10. Health, Fitness and Well‑being | 健康、体能与幸福
Physical activity reduces stress, improves mood, strengthens bones and lowers the risk of obesity, type‑2 diabetes and cardiovascular disease. Social benefits include making friends, developing teamwork and building self‑esteem. Explain how regular sport participation can enhance longevity and quality of life.
体育活动能够缓解压力、改善情绪、强健骨骼，并降低肥胖、2型糖尿病和心血管疾病的风险。社交方面的益处包括结交朋友、培养团队协作能力和建立自尊。能够阐述规律参与运动如何延长寿命、提升生活质量。
Sedentary lifestyles are linked to poor posture and increased health risks. Use the concepts of hypo‑kinetic disease to explain why inactivity leads to conditions like coronary heart disease. Suggest realistic strategies: active travel, screen‑time limits, and joining a lunch‑time club.
久坐不动的生活方式与不良体态以及更高的健康风险息息相关。运用“运动不足病”这一概念解释为什么缺乏运动会导致冠心病等疾病。提出切实可行的策略：主动出行、限制屏幕时间、参加午间运动俱乐部。
11. Injury Prevention and Safety | 伤害预防与安全
Prevent injuries through a thorough warm‑up (pulse‑raiser, dynamic stretches, sport‑specific drills) and cool‑down (gentle jogging, static stretches). Use the R.I.C.E. method for minor injuries: Rest, Ice, Compression, Elevation. Recognise fractures, dislocations, sprains and strains by their signs and symptoms.
通过充分的热身（提高心率、动态拉伸、专项练习）和整理活动（缓和慢跑、静态拉伸）预防损伤。轻微损伤应采用 R.I.C.E. 原则处理：休息、冰敷、加压、抬高。要能根据症状和体征分辨骨折、脱臼、扭伤和拉伤。
Understand the importance of correct clothing, PPE, playing within the rules, and checking equipment. For school practical sessions, always remove jewellery, tie back long hair, and follow the teacher’s safety instructions. Risk assessments help identify potential hazards beforehand.
了解正确着装、使用个人防护装备、遵守规则以及检查器材的重要性。在学校实践课中，务必取下首饰、束起长发并听从教师的安全指导。风险评估有助于提前识别潜在危险。
12. Mock Test and Reflection | 模拟测试与反思
At the end of each week, complete a short mixed‑topic quiz covering the areas revised. Use WJEC‑style questions: short‑answer, data response and extended writing. For example, “Explain how the cardiovascular and respiratory systems work together to deliver oxygen to the quadriceps during a 1500 m run.”
每周结束时，完成一套涵盖本周复习内容的综合性小测验。试题采用 WJEC 风格，包括简答题、数据分析题和拓展写作题。例如：“解释在1500米跑中，心血管系统和呼吸系统如何协同工作，将氧气输送至股四头肌。”
After marking, record your score and write two specific targets for the following week. Focus on command words: “describe”, “explain”, “evaluate”. Evaluate answers have a conclusion plus two supported reasons. Share your progress with a study partner or family member to stay accountable.
批改后，记录得分并写下两个具体的下周目标。关注指令词：“描述”、“解释”、“评价”。评价类答案需要包含结论和两个有依据的理由。与学习伙伴或家人分享进度，互相监督，保持备考责任感。
