1. Health, Fitness and Well-being | 健康、体能与幸福感

Health is a holistic state of complete physical, mental and social well-being, not merely the absence of disease. Fitness, on the other hand, refers to the body’s ability to cope with the demands of everyday life and physical activity. While you can be healthy without being highly fit, improving fitness usually supports better overall health. Well-being combines how you feel physically, emotionally and socially, and it can be boosted by regular exercise, good sleep, strong relationships and a positive mindset.

健康是一种身体、心理和社交完全安好的整体状态，而不仅仅是没有疾病。体能则是指身体满足日常生活和身体活动需求的能力。你可以在身体不太强壮的情况下保持健康，但提升体能通常有助于改善整体健康。幸福感结合了你身体、情感和社交上的感受，规律运动、良好睡眠、稳固的人际关系和积极心态都能增强幸福感。

• Physical health: efficient body systems, resistance to illness.
• Mental health: reduced stress, improved mood and self-esteem.
• Social health: teamwork, communication, sense of belonging.

• 身体健康：高效的身体系统，抵抗疾病。
• 心理健康：减压，改善情绪和自尊。
• 社交健康：团队合作，沟通，归属感。

2. The Components of Fitness | 体能的组成部分

Fitness breaks down into two groups: health-related components that underpin general well-being, and skill-related components that enhance sports performance. A balanced training programme targets multiple components rather than focusing on just one, allowing you to perform across a range of activities and reduce injury risk.

体能分为两大类：支撑整体健康的健康相关要素，以及提升运动表现的技能相关要素。一个均衡的训练计划会针对多个要素，而不仅仅是某一个，这让你能够在各种活动中表现出色，并降低受伤风险。

Health-Related | 健康相关	Skill-Related | 技能相关
Cardiovascular endurance | 心血管耐力	Agility | 灵敏性
Muscular strength | 肌肉力量	Balance | 平衡
Muscular endurance | 肌肉耐力	Coordination | 协调性
Flexibility | 柔韧性	Power | 爆发力
Body composition | 身体成分	Reaction time | 反应时
	Speed | 速度

For example, a gymnast needs exceptional balance and flexibility, while a marathon runner relies heavily on cardiovascular endurance and muscular endurance. Most sports demand a combination of several components, which is why cross-training is so valuable.

例如，体操运动员需要出众的平衡和柔韧性，而马拉松选手则高度依赖心血管耐力和肌肉耐力。大多数运动需要多种要素的组合，因此交叉训练非常宝贵。

3. Principles of Training (SPORT & FITT) | 训练原则 (SPORT 与 FITT)

Training principles explain why and how the body adapts to exercise. Applying SPORT and FITT keeps sessions safe, progressive and effective. Without these principles, you risk hitting a plateau, losing motivation, or getting injured.

训练原则解释了身体为何以及如何适应运动。运用 SPORT 和 FITT 原则能够确保训练安全、渐进且有效。如果不遵循这些原则，你可能会遭遇瓶颈期、动力下降或受伤。

The SPORT acronym helps you remember the key rules:

SPORT 助记符帮你记住关键规则：

• Specificity | 专项性 – training must match the demands of your sport or goal. A swimmer trains differently from a weightlifter.
• Progression | 渐进性 – gradually increase workload to keep challenging the body. Doing the same session every week leads to stagnation.
• Overload | 超负荷 – work harder than normal to force adaptation. This is where the FITT principle comes in.
• Reversibility | 可逆性 – fitness gains are lost when you stop training. ‘Use it or lose it’ rings true after as little as two weeks of inactivity.
• Tedium | 枯燥性 – boredom kills motivation; vary your training to stay engaged. Switching between circuit, game-based and continuous sessions works wonders.

The FITT principle defines how to apply overload safely: Frequency (how often), Intensity (how hard), Time (how long), and Type (what kind of exercise). By adjusting one variable at a time, you can progressively overload without excessive fatigue.

FITT 原则定义了如何安全地施加超负荷：频率（多久一次）、强度（多努力）、时间（多长时间）和类型（哪种运动）。每次只调整其中一个变量，你就可以在不造成过度疲劳的情况下渐进式地施加超负荷。

4. Methods of Training | 训练方法

Different training methods target different components of fitness. Selecting the right method is part of applying the specificity principle, and combining methods keeps tedium at bay.

不同的训练方法针对不同的体能要素。选择合适的训练方法是运用专项性原则的一部分，而结合多种方法则可以避免枯燥。

• Continuous training | 持续训练 – aerobic exercise at a steady pace for at least 20 minutes. Improves cardiovascular endurance. Example: jogging, cycling. | 持续进行至少 20 分钟的稳态有氧运动。提升心血管耐力。例如：慢跑、骑行。
• Interval training | 间歇训练 – alternating periods of high-intensity effort and recovery. Develops speed and can improve both aerobic and anaerobic fitness. | 高强度运动和恢复期交替进行。提升速度，可同时改善有氧和无氧体能。
• Fartlek training | 法特莱克训练 – ‘speed play’ that blends continuous running with bursts of faster pace. Mimics the changing intensity of games like football or hockey. | “速度游戏”，在持续跑动中穿插快速冲刺。模拟足球或曲棍球等比赛不断变化的强度。
• Circuit training | 循环训练 – a sequence of stations targeting different muscle groups or fitness components. Builds muscular endurance, strength and cardiovascular fitness depending on how it is designed. | 一系列针对不同肌群或体能要素的站点。根据设计可增强肌肉耐力、力量和心血管体能。
• Weight (resistance) training | 负重（抗阻）训练 – using free weights, machines or body weight to overload muscles. Heavy loads with low reps develop strength; lighter loads with high reps develop endurance. | 利用自由重量、器械或自重对肌肉施加超负荷。大重量低次数发展力量；小重量高次数发展耐力。

5. The Skeletal and Muscular Systems | 骨骼与肌肉系统

A solid grasp of anatomy helps you analyse movement, improve technique and understand injury prevention. The skeleton provides support, protection, movement (as levers), mineral storage and blood cell production. Muscles pull on bones across joints to create movement, working in antagonistic pairs.

扎实的解剖学知识有助于你分析动作、改进技术并理解如何预防受伤。骨骼提供支撑、保护、运动（作为杠杆）、矿物质储存和血细胞生成。肌肉跨过关节牵拉骨骼产生运动，以拮抗对的形式工作。

Key bones to learn: cranium (skull), clavicle (collarbone), scapula (shoulder blade), humerus, radius, ulna, vertebrae, pelvis, femur, patella, tibia, fibula. Key muscles: deltoid, pectorals, biceps, triceps, abdominals, quadriceps, hamstrings, gastrocnemius, gluteals, latissimus dorsi.

需要掌握的关键骨骼：颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、脊椎骨、骨盆、股骨、髌骨、胫骨、腓骨。关键肌肉：三角肌、胸肌、肱二头肌、肱三头肌、腹肌、股四头肌、腘绳肌、腓肠肌、臀肌、背阔肌。

Movement types occur at synovial joints: flexion (decreasing angle, e.g. bicep curl) and extension (increasing angle, e.g. kicking a ball); abduction (moving away from the body midline) and adduction (moving towards the midline); rotation; and plantarflexion/dorsiflexion at the ankle. An antagonist pair example: during a bicep curl, the biceps contracts (agonist) while the triceps relaxes (antagonist).

运动类型发生在滑液关节上：屈曲（角度减小，如肱二头肌弯举）和伸展（角度增大，如踢球）；外展（远离身体正中面）和内收（靠近正中面）；旋转；以及踝关节的跖屈/背屈。拮抗对示例：做肱二头肌弯举时，肱二头肌收缩（主动肌），肱三头肌放松（拮抗肌）。

6. Cardiovascular and Respiratory Systems | 心血管与呼吸系统

The cardiovascular system (heart, blood vessels, blood) transports oxygen, nutrients and waste, while the respiratory system (lungs, diaphragm, airways) handles gas exchange. During exercise, these systems work harder to meet the muscles’ increased demand for oxygen. Understanding their immediate and long-term responses helps you monitor intensity and appreciate the benefits of regular training.

心血管系统（心脏、血管、血液）运输氧气、营养物质和废物，而呼吸系统（肺、横膈膜、气道）负责气体交换。运动中，这两个系统会更努力地工作，以满足肌肉增加的氧气需求。了解它们的即时和长期反应有助于你监控运动强度，并认识到规律训练的好处。

Immediate effects (short-term): heart rate increases (measured in beats per minute, bpm), stroke volume (blood pumped per beat) rises, cardiac output (heart rate × stroke volume) increases, breathing rate quickens and deepens, and tidal volume grows. Long-term adaptations: resting heart rate lowers, stroke volume increases at rest, heart muscle becomes stronger and more efficient, lung capacity can improve, and recovery rate after exercise speeds up.

即时效应（短期）：心率增加（以每分钟心跳数 bpm 衡量），每搏输出量（每次心跳泵出的血量）增加，心输出量（心率 × 每搏输出量）增加，呼吸频率加快加深，潮气量增大。长期适应：静息心率下降，静息每搏输出量增大，心肌变得更强壮高效，肺活量可得到提升，运动后恢复速率加快。

Cardiac output (Q) = Heart rate (HR) × Stroke volume (SV)

最大心率估算 (HRmax) ≈ 220 – age | 最大心率 ≈ 220 – 年龄

7. Movement Analysis and Planes/Axes | 动作分析与平面/轴

Analysing movement through planes and axes adds precision to your understanding of technique and helps coaches design drills that replicate match demands. Every movement can be described in terms of the imaginary flat surface it runs along (plane) and the line it rotates around (axis).

通过平面和轴来分析动作，能让你更精准地理解技术，并帮助教练设计出能模拟比赛要求的训练。每个动作都可以用其运行的假想平面（平面）和旋转的假想线（轴）来描述。

Plane (平面)	Axis (轴)	Example movement (动作示例)
Sagittal (矢状面) – splits body left/right	Frontal (额状轴/横轴) – through the hips side to side	Somersault, sprinting knee drive (前空翻，冲刺提膝)
Frontal (额状面) – splits body front/back	Sagittal (矢状轴) – through the belly button front to back	Cartwheel, lateral raise (侧手翻，侧平举)
Transverse (水平面) – splits body top/bottom	Longitudinal (垂直轴) – through the head to feet vertically	Discus spin, golf swing (铁饼旋转，高尔夫挥杆)

When you perform a bicep curl, the movement happens predominantly in the sagittal plane around the frontal axis. Recognising this helps you isolate the correct muscles and avoid compensatory movements.

当你做肱二头肌弯举时，动作主要在矢状面绕额状轴进行。认识到这一点有助于你孤立正确的肌肉，避免代偿性动作。

8. Skill Acquisition and Feedback | 技能习得与反馈

Physical Education distinguishes between ability (innate, stable traits such as speed or coordination) and skill (learned, goal-directed actions like a basketball set shot). Skills develop through practice, moving from a cognitive stage where you make frequent errors, to an associative stage where you refine technique, and finally to an autonomous stage where the skill feels effortless.

体育区分了能力（与生俱来的稳定特质，如速度或协调性）和技能（后天习得的、有目标指向的动作，如篮球跳投）。技能通过练习逐步发展，从频繁出错的认知阶段，到打磨技术的联结阶段，最后到达动作驾轻就熟的自律阶段。

Feedback is the information you receive about performance and is critical for improvement. Intrinsic feedback comes from your own senses (you feel your foot connect cleanly with the ball). Extrinsic feedback comes from outside sources such as a coach, video analysis, or the scoreboard. Knowledge of results tells you the outcome (goal scored/missed); knowledge of performance describes the quality of the movement (your follow-through was too short). Effective feedback is timely, specific and constructive.

反馈是你收到的关于表现的信息，对改进至关重要。内在反馈来自你自己的感官（你能感觉到脚干净利落地触球）。外在反馈来自外部来源，比如教练、视频分析或记分板。结果知晓告诉你最终结果（得分/失误）；表现知晓描述动作的质量（你的随挥动作太短）。有效的反馈应当及时、具体且有建设性。

• Positive feedback: what you did well – builds confidence. | 积极反馈：你做得好的地方——建立信心。
• Negative feedback: what needs correcting – must be delivered sensitively. | 消极反馈：需要纠正的地方——表达方式需谨慎。
• Terminal feedback: given after performance. | 终末反馈：在表现之后给予。
• Concurrent feedback: given during performance. | 同步反馈：在表现过程中给予。

9. Nutrition and Hydration in Sport | 运动营养与补水

Fueling correctly can be the difference between fading in the final quarter and finishing strong. Macronutrients provide energy and building blocks: carbohydrates are the body’s preferred fuel for moderate-to-high intensity exercise; proteins repair and build muscle tissue; fats supply energy for low-intensity, long-duration activities and support cell function. Micronutrients (vitamins and minerals) don’t provide energy directly but enable countless metabolic processes, from calcium strengthening bones to iron carrying oxygen in the blood.

恰当的能量补充，可能决定了你是在最后一节体力不支，还是强势收尾。宏量营养素提供能量和构建基础：碳水化合物是身体在中高强度运动时的首选燃料；蛋白质修复和构建肌肉组织；脂肪为低强度长时间活动供能，并支持细胞功能。微量营养素（维生素和矿物质）不直接提供能量，但参与无数代谢过程，从钙强化骨骼，到铁在血液中运输氧气。

Hydration is equally important. Losing just 2% of body weight through sweat can impair performance, reaction time and decision-making. Drink water throughout the day, not just during exercise. For intense sessions lasting over 60 minutes, isotonic sports drinks can replenish fluids, electrolytes and carbohydrates simultaneously.

补水同样重要。因出汗流失仅 2% 的体重，就可能影响运动表现、反应时和决策能力。要全天随时喝水，而不只是运动期间。对于持续超过 60 分钟的高强度运动，等渗运动饮料可以同时补充液体、电解质和碳水化合物。

Athlete’s plate model: roughly one-third carbohydrates (pasta, rice, wholegrains), one-third protein (chicken, fish, beans), and one-third vegetables/fruits, with a small amount of healthy fats (avocado, nuts). Timing matters too: a carbohydrate-rich meal 2–3 hours before exercise, and protein plus carbohydrates within 30–60 minutes after exercise to support recovery.

运动员餐盘模型：大约三分之一碳水化合物（意面、米饭、全谷物），三分之一蛋白质（鸡肉、鱼、豆类），三分之一蔬菜/水果，外加少量健康脂肪（牛油果、坚果）。时机也很关键：运动前 2–3 小时摄入富含碳水的餐食，运动后 30–60 分钟内补充蛋白质加碳水化合物以支持恢复。

10. Risk Assessment and Safe Practice | 风险评估与安全实践

Safe practice is not an afterthought—it is the foundation that allows you to train and compete with confidence. A warm-up prepares the body gradually: it raises heart rate, increases blood flow to muscles, improves range of motion and rehearses sport-specific movements, dramatically lowering the chance of strains and sprains. A cool-down helps remove waste products like lactic acid and gradually returns the heart rate to resting levels, reducing dizziness and muscle soreness.

安全实践不是事后考虑的物品——它是让你能够充满信心地训练和比赛的基础。热身让身体逐步做好准备：它提高心率，增加肌肉血流量，改善关节活动度，并演练专项运动动作，极大降低肌肉拉伤和关节扭伤的概率。整理活动帮助清除乳酸等代谢废物，让心率逐渐恢复到静息水平，减少头晕和肌肉酸痛。

A typical warm-up structure: pulse raiser (light jog, skip) → dynamic stretching (lunges, leg swings, arm circles) → sport-specific drills. A cool-down reverses the process: gentle jogging or walking → static stretching held for 20–30 seconds per muscle group.

典型的热身结构：脉搏提升（慢跑、跳跃）→ 动态拉伸（弓步、摆腿、手臂画圈）→ 专项练习。整理活动则反向进行：轻柔慢跑或步行 → 每个肌群保持 20–30 秒的静态拉伸。

Risk assessments in PE involve checking equipment, facilities and environmental conditions. Always follow rules, listen to instructions, use correct techniques, wear appropriate clothing and protective gear, and inform the teacher immediately of any injuries or hazards. A PAR-Q (Physical Activity Readiness Questionnaire) helps identify any health concerns before starting a new programme.

体育中的风险评估包括检查设备、设施和环境条件。始终遵守规则，听从指导，使用正确技术，穿着合适的衣物和护具，并立即向老师报告任何受伤或危险情况。PAR-Q（身体活动准备问卷）有助于在开始新计划之前识别任何健康隐患。

11. Goal Setting and Mental Preparation | 目标设定与心理准备

Physical performance is as much mental as it is physical. Goal setting using SMARTER targets (Specific, Measurable, Achievable, Relevant, Time-bound, Evaluated, Reviewed) gives you a clear roadmap. For instance, ‘improve my 1500 m time by 10 seconds within 6 weeks by attending two extra interval sessions per week’ is far more motivating than ‘get fitter’.

运动表现既取决于身体，也同样取决于心理。使用 SMARTER 目标（具体、可衡量、可实现、相关、有时限、评估、回顾）进行目标设定，能让你获得清晰的路线图。例如，“在 6 周内通过每周增加两次间歇训练，将 1500 米成绩提高 10 秒”，这比’增强体质’更能激励人。

Mental preparation techniques include imagery (visualising yourself performing a skill perfectly—your brain fires similar neural pathways as during actual movement), positive self-talk (replacing ‘I can’t’ with ‘I’ll do my best’), and breathing exercises to manage anxiety. These tools help you stay focused under pressure and bounce back from mistakes during competition.

心理准备技术包括意象训练（在脑海中想象自己完美地执行技能——大脑激发的神经通路与实际运动时相似）、积极自我对话（把“我做不到”换成“我会尽最大努力”），以及管理焦虑的呼吸练习。这些工具帮助你在压力下保持专注，并在比赛中从失误中迅速恢复。

12. Social and Ethical Issues in Sport | 体育中的社会与伦理议题

Sport does not exist in a vacuum. Understanding issues like sportsmanship, gamesmanship and deviance helps you reflect on your own behaviour as a performer and spectator. Sportsmanship is fair, respectful conduct and graciousness whether you win or lose. Gamesmanship bends the rules without technically breaking them—such as time-wasting or deliberately distracting an opponent. Deviance crosses the line into cheating, such as deliberate fouls, doping or match-fixing, and carries serious consequences.

体育并非存在于真空中。理解体育精神、竞赛取巧和越轨行为等问题，能帮助你反思自己作为参与者和观众的行为。体育精神是公平、尊重对手和胜不骄败不馁的风度。竞赛取巧在不直接违规的情况下曲解规则——比如拖延时间或故意干扰对手。越轨行为则跨越界限沦为作弊，例如故意犯规、使用兴奋剂或操纵比赛，并会带来严重后果。

Performance-enhancing drugs (PEDs) are prohibited because they undermine fair play and can cause severe health damage. Common categories include anabolic steroids (increase muscle mass), stimulants (boost alertness, mask fatigue) and beta-blockers (reduce heart rate, used in precision sports). Anti-doping organisations enforce strict testing and sanctions to protect the integrity of sport.

兴奋剂被禁止，因为它们破坏公平竞争，并可能导致严重的健康损害。常见类别包括合成代谢类固醇（增加肌肉质量）、兴奋剂（提升警觉性，掩盖疲劳）和 β-受体阻滞剂（降低心率，用于精准类运动）。反兴奋剂组织执行严格的检测和制裁以保护体育的纯洁性。
