1. Articular System Foundations | 关节系统基础
The articular system is the scaffolding of human movement. A synovial joint, such as the knee or shoulder, features a joint capsule, synovial membrane secreting lubricating fluid, and articular cartilage that reduces friction. Memorise the six types: ball-and-socket (multi-axial, e.g., hip), hinge (uniaxial, e.g., elbow), pivot (rotation, e.g., atlas-axis), condyloid (biaxial, e.g., wrist), saddle (thumb), and gliding (carpals). Relate each type to its degrees of freedom — the number of planes in which it permits movement — to avoid confusion. Think ‘ball-and-socket = largest ROM’, ‘hinge = door analogy’.
关节系统是人体运动的骨架。滑膜关节（如膝关节或肩关节）由关节囊、分泌滑液的滑膜和减少摩擦的关节软骨构成。记住六种类型：球窝关节（多轴，如髋）、屈戌关节（单轴，如肘）、车轴关节（旋转，如寰枢关节）、髁状关节（双轴，如腕）、鞍状关节（拇指）和平面关节（腕骨间关节）。将每种类型与其自由度（允许运动的平面数）联系起来，可避免混淆。记住：“球窝 = 最大活动度”，“屈戌 = 门轴类比”。
2. Muscular Contraction Types | 肌肉收缩类型
Muscle actions are not all about shortening. Isotonic contraction involves a change in muscle length against a constant load: concentric (shortening, e.g., upward phase of bicep curl) and eccentric (lengthening under tension, e.g., lowering phase). Isometric contraction generates force without length change, such as holding a plank. An isokinetic contraction, often tested in rehabilitation, maintains constant angular velocity using specialised dynamometers. Link each term to its Greek roots: ‘iso-‘ (same), ‘tonic’ (tension), ‘metric’ (length), ‘kinetic’ (motion). In exams, always specify the type of contraction when analysing a movement phase — this shows precise knowledge.
肌肉活动并非总是缩短。等张收缩指在恒定负荷下肌肉长度改变：向心收缩（缩短，如哑铃弯举上举阶段）和离心收缩（张力下延长，如下放阶段）。等长收缩产生力量但长度不变，例如平板支撑。等速收缩通常用于康复测试，利用专用测力设备维持恒定角速度。将术语与希腊词根联系起来：“iso-”（相同）、“tonic”（张力）、“metric”（长度）、“kinetic”（运动）。在考试中分析动作阶段时务必指明收缩类型，这能体现知识的准确性。
3. Planes and Axes of Motion | 运动平面与轴
Every joint action can be described by a plane and its corresponding axis of rotation. The sagittal plane divides the body into left and right; movements here (flexion, extension) occur around a frontal (mediolateral) axis — think of a somersault. The frontal plane separates anterior and posterior; abduction/adduction happen around a sagittal (anteroposterior) axis — like a cartwheel. The transverse plane splits top from bottom; rotation occurs around a vertical (longitudinal) axis — akin to a pirouette. A powerful memory trick: the axis is always perpendicular to the plane. Draw a stick figure and label the planes with arrows; then cement the relationship: sagittal plane + frontal axis = running stride.
每个关节动作都可以用平面和对应的旋转轴来描述。矢状面将身体分为左右两部分；在此平面上的运动（屈、伸）绕额状轴（冠状轴）发生——想象前空翻。额状面分隔前后；外展、内收绕矢状轴完成——像侧手翻。水平面将身体分为上下两部分；旋转绕垂直轴——类似芭蕾旋转。强力记忆技巧：轴总是垂直于平面。画一个简笔画，用箭头标出平面，然后巩固关系：矢状面 + 额状轴 = 跑步步幅。
4. Levers and Mechanical Advantage | 杠杆与机械利益
The human body operates with three classes of levers. A first-class lever has the fulcrum between effort and load (e.g., neck extension – load: head weight, effort: posterior neck muscles, fulcrum: atlanto-occipital joint). A second-class lever places the load between fulcrum and effort, providing mechanical advantage for force production; the calf raise is a classic example (fulcrum: ball of foot, load: body weight through tibia, effort: gastrocnemius). Third-class levers have effort between fulcrum and load, favouring speed and range of motion, such as a bicep curl. Recall: FLE (1st), LFE (2nd), FEL (3rd) — first letter is the middle component. Most body movements are third-class, so highlight that in essays on speed and agility.
人体以三类杠杆运作。第一类杠杆支点位于动力与阻力之间（如颈后伸——阻力：头部重量，动力：颈后肌群，支点：寰枕关节）。第二类杠杆阻力在支点和动力之间，能产生力学优势利于发力；提踵是经典例子（支点：脚掌前端，阻力：通过胫骨传递的体重，动力：腓肠肌）。第三类杠杆动力介于支点与阻力之间，有利于速度与活动范围，如哑铃弯举。记忆口诀：FLE（第一类）、LFE（第二类）、FEL（第三类）——首字母代表中间部分。人体多数运动是第三类杠杆，在速度与灵敏性的论述题中要特别强调这一点。
5. Energy Systems Integration | 能量系统整合
Understanding how ATP is regenerated is fundamental. The phosphocreatine (PC) system provides immediate energy for up to 10 seconds of maximal effort (e.g., 100 m sprint). It operates anaerobically without oxygen. The anaerobic glycolytic system (or lactate system) dominates from ~10 s to 2 min, breaking down glucose without oxygen, resulting in pyruvate conversion to lactate and increasing acidity. The aerobic system uses oxygen to metabolise carbohydrates and fats for prolonged exercise. Teach yourself the timelines: PC = 0–10 s, glycolytic = 10 s–2 min, aerobic = 2 min+. For definitions, always include substrate, duration, by-products, and sporting example. Cross-link intensity with energy system: high intensity relies on anaerobic; moderate intensity on aerobic.
理解 ATP 如何再生是基础。磷酸肌酸（PC）系统为全力运动提供即刻能量，持续最多 10 秒（如 100 米冲刺）。它在无氧条件下运作。无氧糖酵解系统（乳酸系统）主导约 10 秒至 2 分钟的运动，无氧分解葡萄糖，导致丙酮酸转化为乳酸并增加酸度。有氧系统利用氧气代谢碳水化合物和脂肪，供能持续长时间运动。记住时间线：PC = 0–10 秒，糖酵解 = 10 秒–2 分钟，有氧 = 2 分钟以上。定义时永远包括底物、时长、副产物和运动实例。将强度与能量系统交叉关联：高强度依赖无氧；中等强度依赖有氧。
6. Cardiovascular Dynamics | 心血管动力学
Key cardiovascular terms can be memorised by linking them to the cardiac cycle. Stroke volume (SV) is the volume of blood ejected per beat; heart rate (HR) is beats per minute; cardiac output (Q) = SV × HR. During exercise, Q increases through both variables, but SV plateaus at ~40–60% of maximal intensity in untrained individuals. Venous return — the flow of blood back to the heart — relies on the skeletal muscle pump, respiratory pump, and venoconstriction. Define Starling’s law: increased venous return stretches cardiac muscle, leading to a more forceful contraction. Write the equation on your flashcards: Q = SV × HR. Then add the determinants of SV: preload, contractility, afterload. Use a diagram of the pressure-volume loop to visualise.
关键心血管术语可通过与心动周期的关联来记忆。每搏输出量（SV）是每次心跳射出的血量；心率（HR）是每分钟心跳次数；心输出量（Q）= SV × HR。运动时 Q 通过两个变量增加，但 SV 在未训练者在约 40–60% 最大强度时达到平台期。静脉回流——血液流回心脏——依赖于骨骼肌泵、呼吸泵和静脉收缩。斯达林定律：静脉回流增加会拉伸心肌，使收缩更加强有力。在闪卡上写下方程：Q = SV × HR。然后添加 SV 的决定因素：前负荷、心肌收缩力、后负荷。用压力 – 容积环图来可视化。
7. Respiratory Responses to Exercise | 运动时的呼吸反应
Minute ventilation (VE) = tidal volume (TV) × breathing frequency (f). During incremental exercise, TV increases initially then plateaus; further rises in VE come from increased breathing rate. The term ventilatory threshold refers to the point at which ventilation increases disproportionately to oxygen uptake, linked to lactate accumulation. Gaseous exchange at the alveoli depends on partial pressure gradients (ppO₂ and ppCO₂). Memorise the oxyhaemoglobin dissociation curve shift: during exercise, increased temperature and acidity (Bohr effect) shift the curve right, enhancing oxygen unloading to working muscles. Use the mnemonic ‘CADET, face Right!’ for shift right: CO₂, Acid (H⁺), DPG, Exercise, Temperature — all increase.
每分通气量（VE）= 潮气量（TV）× 呼吸频率（f）。在递增运动时，TV 起初增加然后趋于平稳；VE 的进一步上升来自呼吸频率的提高。术语“通气阈”指通气量不成比例地超过摄氧量的那一点，与乳酸积累有关。肺泡处的气体交换取决于分压梯度（ppO₂ 和 ppCO₂）。记住氧合血红蛋白解离曲线的偏移：运动时，温度升高和酸度增加（波尔效应）使曲线右移，促进氧气向工作肌肉的释放。用口诀“CADET, face Right!”记忆右移因素：CO₂、酸（H⁺）、DPG、运动、温度——全都增加。
8. Neuromuscular Adaptations to Training | 训练引起的神经肌肉适应
Chronic adaptations to training involve both muscular and neural changes. Hypertrophy refers to an increase in cross-sectional area of muscle fibres, primarily type II fibres, via increased protein synthesis and satellite cell activity. Hyperplasia — an increase in fibre number — is still debated in humans but may occur in extreme overload. Neural adaptations include enhanced motor unit recruitment, rate coding, and synchronisation, which explain early strength gains before visible hypertrophy. Define rate of force development (RFD) as the speed at which force is produced, critical for explosive athletes. Use a timeline: first 4–6 weeks of resistance training = neural domination; after 8–12 weeks = hypertrophy noticeable. Emphasise in essays that structural and neural adaptations are concurrent but early gains are neural.
训练引起的慢性适应包括肌肉与神经两方面改变。肥大（hypertrophy）指肌纤维横截面积增加，主要在 II 型纤维，通过提高蛋白质合成和卫星细胞活性实现。增生（hyperplasia）即纤维数量增加，在人类中仍有争议，但可能在极端负荷下发生。神经适应包括运动单位募集增强、放电频率及同步化提高，这解释了肉眼可见肥大之前早期力量的增长。力量发展速率（RFD）定义为产生力量的速度，对爆发力项目运动员至关重要。使用时间线：抗阻训练前 4–6 周 = 神经主导；8–12 周后 = 肥大显现。在论述题中强调，结构性和神经性适应同时发生，但早期收益主要来自神经适应。
9. Sport Psychology: Anxiety and Arousal | 运动心理学：焦虑与唤醒
Arousal is the physiological and psychological state of alertness, on a continuum from deep sleep to extreme excitement. It is not inherently negative. Anxiety is a negative emotional state with feelings of nervousness and worry, often composed of cognitive (thoughts) and somatic (physical) components. The inverted-U hypothesis (Yerkes-Dodson) states that performance improves with increased arousal up to an optimal point, after which it declines. For complex skills, optimal arousal is lower; for simple or gross skills, it is higher. Drive theory suggests a linear relationship for well-learned tasks: performance = habit × drive. Use the Catastrophe model when anxiety is high: once beyond optimal arousal in the presence of cognitive anxiety, performance drops sharply rather than gradually. Match each theory to a specific sporting scenario to ensure you can apply rather than just describe.
唤醒是生理和心理的警觉状态，从深度睡眠到极度兴奋的连续体。它本身并非负面。焦虑是一种负面情绪状态，带有紧张和担忧感，通常由认知性（思维）和躯体性（生理）成分组成。倒 U 型假说（耶克斯 – 多德森）认为，表现随唤醒提高而提升，直至某一最佳点，之后下降。复杂技能最佳唤醒水平较低；简单或大肌肉技能最佳唤醒水平较高。驱力理论认为对于熟练掌握的任务是线性关系：表现 = 习惯 × 驱力。当焦虑水平高时，用突变模型：一旦在认知焦虑存在时超过最佳唤醒，表现会急剧而不是逐渐下降。将每种理论与具体运动情境匹配，确保自己能应用而不仅是描述。
10. Biomechanical Principles: Angular Motion | 生物力学原理：角运动
Angular motion is rotation around an axis. Key analogues to linear quantities exist: angular velocity (ω) is rate of spin; angular acceleration (α) is change in angular velocity per time. Moment of inertia (I) depends on mass and its distribution from the axis. The closer the mass is to the axis, the smaller I, allowing faster rotation — a principle exploited by a tucked somersault. Angular momentum (L) = I × ω and is conserved if no external torque acts. In diving or gymnastics, reducing I by tucking increases ω. Define torque as the turning effect of a force: τ = F × d (force × perpendicular distance from axis). Remember that torque causes angular acceleration. Use formulae on flashcards and practice explaining the spinning skater as the classic exam example.
角运动是绕轴的旋转。存在与直线运动量对应的术语：角速度（ω）是旋转速率；角加速度（α）是角速度的变化率。转动惯量（I）取决于质量及其与轴的距离分布。质量离轴越近，I 越小，能够旋转得更快——这是团身空翻所利用的原理。角动量（L）= I × ω，若无外力矩作用则守恒。在跳水或体操中，通过团身减小 I 来增加 ω。力矩定义为力的转动效应：τ = F × d（力乘以与轴的垂直距离）。记住力矩引起角加速度。在闪卡上使用公式，练习用旋转的滑冰者作为经典考试例子来解释。
11. Training Methods and Periodisation | 训练方法与周期化
Effective training programmes use periodisation to prevent overtraining and peak at the right time. A macrocycle is the long-term plan (e.g., annual plan); mesocycles are monthly or phase-specific blocks (e.g., hypertrophy, strength, power); microcycles are weekly structures. Key terminology: progressive overload — gradually increasing stress to force adaptation; specificity — training must match the energy system, movement pattern, and muscle groups of the target activity; reversibility — gains are lost when training stops (‘use it or lose it’). FITT principle: Frequency, Intensity, Time (duration), Type. For strength, differentiate between maximal strength, hypertrophy, and power training using reps, sets, and % 1RM. For example, power: 3–5 sets of 3–6 reps at 40–60% 1RM with explosive intent. Use these numbers to back up applied answers.
有效的训练计划运用周期化防止过度训练并在恰当时间达到巅峰。大周期是长期计划（如年度计划）；中周期是月度或分阶段板块（如肥大、力量、爆发力）；小周期是周结构。关键术语：渐进超负荷——逐步增加负荷以迫使适应；专项性——训练必须与目标活动的能量系统、动作模式和肌群相符；可逆性——停训后所获能力会丧失（“用进废退”）。FITT 原则：频率（Frequency）、强度（Intensity）、时间（Time）、类型（Type）。在力量训练中，通过次数、组数和 1RM 百分比区分最大力量、肥大和爆发力训练。例如，爆发力：3–5 组 × 3–6 次，40–60% 1RM，意图爆发式发力。用这些数字支撑应用型答案。
12. Skill Acquisition and Feedback | 技能习得与反馈
Motor learning terminology is essential for the coaching sections. Classify skills by characteristics: open vs. closed (environmental stability), gross vs. fine (muscle involvement), discrete, serial, or continuous (clear beginning/end). Feedback types: intrinsic (internal, from proprioceptors) and extrinsic (augmented, from coach/video); knowledge of results (KR) about outcome, knowledge of performance (KP) about movement quality. Fitts and Posner’s stages: cognitive (beginner, lots of trial and error), associative (refining, fewer errors), autonomous (automatic, low attention demand). Schema theory: recall schema (selector program) and recognition schema (evaluates response). Link feedback to learning stage: beginners need KP and immediate positive reinforcement; elite athletes benefit from delayed, precise KR. When defining a motor programme, describe a generalised motor program — the abstract representation of a skill that allows variations (invariant features include order, timing, relative force).
运动学习术语对执教部分至关重要。按特征对技能分类：开放式与封闭式（环境稳定性）、粗大与精细（肌肉参与度）、分立、序列或连续（明确的开始/结束）。反馈类型：内在的（内部，来自本体感受器）和外在的（增强，来自教练/视频）；结果知晓（KR）关于结果，表现知晓（KP）关于动作质量。费茨与波斯纳的阶段：认知阶段（初学者，大量试错）、联结阶段（改进，错误减少）、自动化阶段（自动化，注意需求低）。图式理论：回忆图式（选择程序）和再认图式（评价反应）。将反馈与学习阶段联系：初学者需要 KP 和即时积极强化；精英运动员从延迟的、精确的 KR 中获益。定义运动程序时，描述泛化运动程序——技能的抽象表征，允许变化（不变特征包括顺序、时间和相对力量）。
