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

The skeleton provides structural support, protects vital organs, and serves as attachment points for muscles.
骨骼提供结构支撑，保护重要器官，并作为肌肉的附着点。
Long bones act as levers to facilitate movement, while flat bones offer protection and a large surface area for muscle attachment.
长骨充当杠杆以促进运动，而扁骨则提供保护并具有较大的肌肉附着面积。
Synovial joints such as ball-and-socket and hinge joints allow a wide range of movements; ligaments connect bone to bone and tendons connect muscle to bone.
滑膜关节（如球窝关节和铰链关节）允许多种运动；韧带连接骨与骨，肌腱连接肌肉与骨。
Muscles work in antagonistic pairs — when the agonist contracts, the antagonist relaxes. Isotonic contractions involve movement, while isometric contractions generate force without changing muscle length.
肌肉以拮抗肌对的形式工作——当主动肌收缩时，拮抗肌放松。等张收缩涉及关节运动，而等长收缩产生力量但肌肉长度不变。

2. Energy Systems | 能量系统

The body resynthesises ATP using three energy systems that operate according to the intensity and duration of activity. The ATP-PC system provides immediate energy for up to 10 seconds of maximal effort. Anaerobic glycolysis (lactic acid system) supplies energy for high-intensity efforts lasting up to about 90 seconds, producing lactic acid as a by-product. The aerobic system yields the most ATP and fuels prolonged, low-to-moderate intensity exercise.

身体根据运动强度和持续时间通过三种能量系统重新合成 ATP。ATP-PC 系统为最多 10 秒的最大强度活动提供即时能量。无氧糖酵解（乳酸系统）为持续约 90 秒的高强度运动供能，并产生乳酸副产物。有氧系统产生最多的 ATP，为长时间、中低强度的运动提供能量。

ATP-PC System: ATP → ADP + Pi + energy; PC → Pi + C + energy to re-synthesise ATP.
ATP-PC 系统：ATP → ADP + Pi + 能量；PC → Pi + C + 能量，用于重新合成 ATP。
Lactic acid system: glucose → energy + lactic acid; predominant in 400 m sprint or repeated high intensity efforts.
乳酸系统：葡萄糖 → 能量 + 乳酸；在 400 米冲刺或重复高强度运动中占主导。
Aerobic system: glucose / fatty acids + O₂ → CO₂ + H₂O + large amount of ATP; used in marathon running.
有氧系统：葡萄糖 / 脂肪酸 + O₂ → CO₂ + H₂O + 大量 ATP；在马拉松跑步中使用。

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

Cardiac output (Q) is the volume of blood pumped by the heart per minute and is determined by heart rate × stroke volume. During exercise, heart rate increases, stroke volume rises, and blood is redistributed to working muscles via vasodilation and vasoconstriction (vascular shunt mechanism).

每分心输出量 (Q) 是心脏每分钟泵出的血量，由心率 × 每搏输出量决定。运动时，心率加快，每搏输出量增大，并通过血管舒张和血管收缩（血管分流机制）将血液重新分配到工作肌肉。

Respiratory adaptations include increased tidal volume and breathing frequency, leading to higher minute ventilation. Oxygen debt (EPOC) refers to the extra oxygen consumed after exercise to remove lactic acid and restore the body to its resting state.

呼吸系统的适应包括潮气量和呼吸频率增加，从而提高每分通气量。氧债 (EPOC) 指运动后额外消耗的氧气，用于清除乳酸并使身体恢复至静息状态。

VO₂ max = Cardiac Output × a-vO₂ difference

最大摄氧量 = 心输出量 × 动静脉氧差

4. Skill Acquisition | 运动技能习得

Skills may be classified on continua: open-closed, gross-fine, discrete-serial-continuous, and self-paced–externally paced.

Types of feedback: intrinsic (kinaesthetic), extrinsic (augmented), knowledge of results, knowledge of performance, concurrent, and terminal.
反馈类型：内在（动觉）、外在（增强）、结果反馈、表现反馈、同时反馈和终末反馈。
Practice structures — massed, distributed, fixed, variable — influence skill retention and transfer.
练习结构——集中练习、分散练习、固定练习、变化练习——影响技能保持与迁移。

5. Sports Psychology | 运动心理学

Intrinsic motivation comes from internal satisfaction; extrinsic motivation involves external rewards. Both influence persistence.
内在动机源于内部满足感；外在动机涉及外部奖励。二者均影响坚持性。
Anxiety can be somatic (physical symptoms) or cognitive (mental worry). Optimal arousal follows the inverted-U theory, varying by skill type and personality.
焦虑分为躯体焦虑（身体症状）和认知焦虑（心理担忧）。最佳唤醒水平遵循倒 U 型理论，并因技能类型和个性而异。
Aggression in sport may be hostile or instrumental; it can be managed through calming techniques and strict officiating.
体育运动中的攻击行为可能属于敌意性攻击或工具性攻击；可通过冷静技巧和严格执法加以控制。
Goal setting using the SMART principle (Specific, Measurable, Achievable, Realistic, Time-bound) helps focus effort and monitor progress.
运用 SMART 原则（具体的、可衡量的、可实现的、现实的、有时限的）设定目标有助于集中精力和监测进展。
Mental preparation techniques include imagery, self-talk, relaxation, and pre-performance routines.
心理准备技术包括表象、自我对话、放松和赛前例行程序。

6. Principles and Methods of Training | 训练原则与方法

8. Nutrition and Hydration | 营养与水分

A balanced diet for athletes includes carbohydrates (main energy source), fats (energy and insulation), proteins (growth and repair), along with vitamins, minerals, fibre, and water. Specific nutrient timing can enhance performance: a pre-exercise meal rich in complex carbohydrates, and post-exercise protein for recovery.

运动员的均衡饮食包括碳水化合物（主要能量来源）、脂肪（能量和保暖）、蛋白质（生长和修复），以及维生素、矿物质、纤维和水。特定的营养时机可提升运动表现：运动前餐富含复合碳水化合物，运动后补充蛋白质以促进恢复。

Hydration is critical because water regulates body temperature and transports nutrients; dehydration impairs performance and increases injury risk.
水分摄入至关重要，因为水能调节体温并运输营养物质；脱水会削弱运动表现并增加受伤风险。
Carbohydrate loading can delay fatigue in endurance events lasting more than 90 minutes.
糖原负荷法可在超过 90 分钟的耐力项目中推迟疲劳出现。
Sports drinks containing electrolytes and glucose aid rehydration and maintain energy levels during prolonged exercise.
