2. Applied Anatomy and Physiology | 应用解剖学与生理学

Muscle Fibre Types: Learners must classify type I, type IIa, and type IIx fibres by structural and functional characteristics. Type I fibres are slow-twitch, rich in mitochondria and myoglobin, support aerobic endurance, and fatigue slowly. Type IIx fibres are fast-twitch glycolytic, have high phosphocreatine stores, generate rapid force but fatigue quickly. Type IIa are intermediate fibres, adaptable with training, displaying characteristics of both type I and IIx.

肌纤维类型：学生需要根据结构和功能特征对 I 型、IIa 型和 IIx 型纤维进行分类。I 型纤维是慢肌，富含线粒体和肌红蛋白，支持有氧耐力，疲劳缓慢。IIx 型纤维是快肌糖酵解型，拥有高磷酸肌酸储存量，能产生快速力量但易疲劳。IIa 型是中间型纤维，通过训练可适应，兼有 I 型和 IIx 型特性。

Neural Control and Contraction: The motor unit consists of a motor neurone and the muscle fibres it innervates. The ‘all-or-none’ law states that a motor unit either fires completely or not at all. Wave summation and tetanus allow for graded force production. The sliding filament theory explains contraction: calcium ions released from the sarcoplasmic reticulum bind to troponin, causing tropomyosin to move and expose binding sites on actin, allowing myosin heads to pull the actin filament using ATP hydrolysis.

神经控制与收缩：运动单位由一个运动神经元及其所支配的肌纤维组成。“全或无”定律指出运动单位要么完全兴奋，要么完全不兴奋。波叠加和强直收缩允许分级产生力量。滑动丝理论解释了收缩过程：从肌浆网释放的钙离子与肌钙蛋白结合，导致原肌球蛋白移动并暴露肌动蛋白上的结合位点，使肌球蛋白头利用 ATP 水解释放的能量拉动肌动蛋白丝。

Cardiovascular System: Understanding the cardiac cycle (atrial systole, ventricular systole, diastole) and the conduction system (SA node, AV node, bundle of His, Purkinje fibres) is fundamental. Cardiac output (Q = HR × SV) is regulated by neural, hormonal, and intrinsic factors. Venous return mechanisms and Starling’s law—increased venous return stretches ventricular walls, leading to a stronger contraction and elevated stroke volume—must be explained. Cardiovascular drift describes the gradual rise in heart rate during prolonged steady-state exercise due to decreased stroke volume from fluid loss and thermoregulation demands.

心血管系统：理解心动周期（心房收缩、心室收缩、舒张）和传导系统（窦房结、房室结、希氏束、浦肯野纤维）是基础。心输出量（Q = HR × SV）受神经、激素和内在因素调节。静脉回流机制和斯塔林定律——静脉回流量增加会拉伸心室壁，导致收缩更强、每搏输出量增加——必须予以解释。心血管漂移描述了在长时间稳态运动中，由于体液流失和体温调节需求导致每搏输出量下降，心率逐渐升高的现象。

Respiratory System: Breathing is controlled by neural centres in the medulla oblongata and modulated by chemoreceptors sensitive to CO₂, pH, and O₂. Gaseous exchange occurs at the alveoli and muscle tissues, driven by partial pressure gradients. The oxyhaemoglobin dissociation curve shows how haemoglobin’s affinity for oxygen changes; the Bohr shift explains that increased CO₂ and acidity (lower pH) during exercise reduce affinity, releasing more O₂ to working muscles.

呼吸系统：呼吸由延髓的神经中枢控制，并由对 CO₂、pH 和 O₂ 敏感的化学感受器调节。气体交换在肺泡和肌肉组织处发生，由分压梯度驱动。氧合血红蛋白解离曲线显示了血红蛋白对氧的亲和力如何变化；波尔效应解释了运动时 CO₂ 和酸度增加（pH 降低）会降低亲和力，从而向工作肌肉释放更多 O₂。

Energy Systems: The ATP-PC system provides immediate energy for maximal intensity efforts lasting up to 10 seconds, using phosphocreatine to rapidly resynthesise ATP. The anaerobic glycolytic system produces energy for high-intensity activities up to 60–90 seconds without oxygen, yielding lactate and hydrogen ions. The aerobic system fuels prolonged exercise through carbohydrate and fat oxidation via the Krebs cycle and electron transport chain. The energy continuum concept illustrates how all three systems contribute simultaneously, with dominance shifting according to intensity and duration. Recovery involves restoration of ATP-PC stores, removal of lactate, and replenishment of glycogen and oxygen (EPOC).

能量系统：ATP-PC 系统通过磷酸肌酸快速再合成 ATP，为持续不超过 10 秒的最大强度运动提供即刻能量。无氧糖酵解系统在无氧条件下为持续 60 至 90 秒的高强度活动提供能量，产生乳酸和氢离子。有氧系统通过三羧酸循环和电子传递链氧化碳水化合物和脂肪，为长时间运动供能。能量连续体概念说明三个系统同时贡献能量，其主导地位随强度和时长而转移。恢复涉及 ATP-PC 储备补充、乳酸清除以及糖原和氧气的补充（运动后过量氧耗 EPOC）。

3. Exercise Physiology | 运动生理学

Training Adaptations: Chronic responses to aerobic training include increased stroke volume, decreased resting heart rate, cardiac hypertrophy, increased capillarisation and mitochondrial density, and improved lactate threshold. Anaerobic training leads to enhanced phosphocreatine stores, increased glycolytic enzymes, and improved buffering capacity. Learners should explain these adaptations using detailed physiological mechanisms and apply them to performance.

训练适应：对有氧训练的长期适应包括每搏输出量增加、静息心率下降、心脏肥大、毛细血管密度和线粒体密度增加以及乳酸阈提高。无氧训练导致磷酸肌酸储存增加、糖酵解酶活性增强以及缓冲能力提高。学生应运用详细的生理机制解释这些适应，并将其应用于运动表现。

Nutrition and Ergogenic Aids: A balanced intake of carbohydrates, proteins, and fats is essential, with timing strategies such as pre-event, during-event, and post-event nutrition to optimise performance and recovery. Common ergogenic aids include creatine (enhances ATP-PC system), caffeine (reduces perceived exertion and enhances fat metabolism), and sodium bicarbonate (buffers lactic acid). Students must assess the benefits, risks, and ethical considerations of each aid.

营养与运动补剂：均衡摄入碳水化合物、蛋白质和脂肪至关重要，配合赛前、赛中及赛后的营养策略以优化表现和恢复。常见的运动补剂包括肌酸（增强 ATP-PC 系统）、咖啡因（降低自觉疲劳并促进脂肪代谢）和碳酸氢钠（缓冲乳酸）。学生必须评估每种补剂的益处、风险和道德考量。

Injury Prevention and Rehabilitation: Principles include appropriate warm-up and cool-down, flexibility training, strength conditioning, and the use of protective equipment. Rehabilitation protocols often follow the stages of acute management (e.g., PRICE—Protection, Rest, Ice, Compression, Elevation), followed by progressive loading, mobility exercises, and sport-specific drills before return to play.

损伤预防与康复：原则包括适当的热身和放松、柔韧性训练、力量调节以及防护装备的使用。康复方案通常遵循急性管理阶段（例如 PRICE——保护、休息、冰敷、加压、抬高），随后进行渐进性负荷、活动度练习和专项训练，然后再重返赛场。

4. Biomechanics | 生物力学

Newton’s Laws of Motion: The first law (inertia) states a body remains at rest or in uniform motion unless acted upon by an external force. The second law describes the relationship: Force = mass × acceleration. The third law explains action–reaction pairs. These laws underpin the analysis of sport movements, such as a sprinter driving out of blocks or a footballer kicking a ball.

Force = mass × acceleration

牛顿运动定律：第一定律（惯性）指出物体保持静止或匀速直线运动状态，除非受到外力作用。第二定律描述关系：力 = 质量 × 加速度。第三定律说明作用力与反作用力对。这些定律是分析运动动作的基础，例如短跑运动员蹬离起跑器或足球运动员踢球。

Linear and Angular Motion: Displacement, velocity, and acceleration are linear kinematic descriptors. Momentum = mass × velocity is conserved in collisions. For angular motion, moment of inertia and angular velocity are key; a body’s moment of inertia depends on mass distribution relative to the axis of rotation. An ice skater spinning faster by pulling arms in demonstrates conservation of angular momentum.

Momentum = mass × velocity

线性与角运动：位移、速度和加速度是线性运动学描述量。动量 = 质量 × 速度，在碰撞中守恒。对于角运动，转动惯量和角速度是关键；物体的转动惯量取决于质量相对于转轴的分布。溜冰者通过将手臂收拢而旋转得更快，展示了角动量守恒。

Projectile Motion and Fluid Mechanics: The trajectory of a projectile is determined by release velocity, angle, and height. The Magnus force explains the curved flight of a spinning ball due to pressure differences. Bernoulli’s principle relates faster airflow to lower pressure, fundamental to understanding lift in discus throws and drag in cycling. Levers in the body are classified as first, second, or third class, with most sporting movements involving third-class levers for speed and range of motion.

抛射体运动与流体力学：抛射体的轨迹由出手速度、角度和高度决定。马格努斯效应解释了由于压力差异导致旋转球弧线飞行的原理。伯努利原理将较快的气流与较低的压力联系起来，是理解铁饼飞行中的升力和自行车运动中阻力的基础。人体中的杠杆分为第一、第二或第三类，大多数运动动作涉及第三类杠杆，以获得速度和运动范围。

5. Skill Acquisition | 技能习得

Information Processing Models: Welford’s and Whiting’s models illustrate how we detect environmental stimuli, process decisions, and execute movements. Reaction time, movement time, and response time are distinguished. Hick’s law explains that reaction time increases as the number of stimulus–response choices grows. Memory involves a three-stage model: short-term sensory store, short-term memory (limited capacity, 7±2 items), and long-term memory, with encoding, storage, and retrieval processes.

信息处理模型：韦尔福德和怀廷的模型说明了我们如何检测环境刺激、处理决策并执行动作。反应时、动作时间和响应时间需加以区分。希克定律解释了随着刺激–反应选择数量的增加，反应时随之增长。记忆涉及三阶段模型：短期感觉存储、短期记忆（容量有限，7 ± 2 个项目）和长期记忆，包括编码、存储和提取过程。

Schema Theory and Stages of Learning: Schmidt’s schema theory proposes that we develop generalised motor programmes and adjust them through recall schema (initial conditions and movement parameters) and recognition schema (sensory feedback). Learners progress through cognitive, associative, and autonomous stages. During the cognitive stage, performance is erratic and requires conscious thought; in the autonomous stage, actions become fluent and automatic.

图式理论与学习阶段：施密特的图式理论提出，我们发展了一般运动程序，并通过回忆图式（初始条件和运动参数）与识别图式（感觉反馈）进行调整。学习者经历认知、联结和自主阶段。在认知阶段，表现不稳定且需要意识控制；在自主阶段，动作变得流畅和自动化。

Feedback and Guidance: Feedback can be intrinsic (internal sensory) or extrinsic (external), knowledge of results (KR) or knowledge of performance (KP), concurrent or terminal. Effective guidance includes visual (demonstrations), verbal (instructions), manual (physical manipulation), and mechanical (use of aids). The type and timing of feedback and guidance must be tailored to the learner’s stage to optimise skill acquisition.

反馈与指导：反馈可以是内在的（内部感觉）或外在的（外部），结果知晓（KR）或表现知晓（KP），同步或终末。有效的指导包括视觉（示范）、言语（指导）、手动（身体操纵）和机械（使用辅助工具）。反馈和指导的类型与时机必须根据学习者的所处阶段进行调整，以优化技能习得。

6. Sport Psychology | 运动心理学

Personality and Attitudes: The trait, situational, and interactionist perspectives explain behaviour in sport. The interactionist approach—combining personality traits and environmental factors—is widely accepted. Attitudes are formed through socialisation and can be changed using persuasive communication and cognitive dissonance. The triadic model outlines the cognitive, affective, and behavioural components of attitudes.

人格与态度：特质论、情境论和互动论视角解释了运动中的行为。结合人格特质与环境因素的互动论被广泛接受。态度通过社会化形成，并可通过说服性沟通和认知失调来
