1. Energy Systems and Exercise Physiology | 能量系统与运动生理学
wn rapidly to resynthesise ATP without oxygen, producing no fatiguing by-products. The reaction can be summarised as: PC + ADP → ATP + C. However, PC stores are depleted within seconds and require 3–5 minutes for full recovery.
ATP-PC 系统为持续时间不超过 10 秒的最大强度运动供能（如 100 米冲刺、高翻）。磷酸肌酸（PC）在无氧条件下快速分解，使 ADP 再合成为 ATP，且不产生致疲劳副产品。反应可概括为：PC + ADP → ATP + 肌酸。但 PC 储量数秒内便会耗竭，需要 3–5 分钟才能完全恢复。
When high-intensity effort extends beyond 10 seconds (e.g. 400 m run), the lactic acid system takes over. Glucose is broken down via anaerobic glycolysis, yielding 2 ATP molecules per glucose and producing lactic acid. Lactic acid accumulation lowers muscle pH, inhibiting enzyme activity and causing the familiar burning sensation and temporary muscle fatigue. This system dominates in events lasting 10–90 seconds.
当高强度运动超过 10 秒（如 400 米跑），乳酸系统开始主导。葡萄糖经无氧酵解分解，每分子葡萄糖净得 2 分子 ATP，同时产生乳酸。乳酸堆积使肌肉 pH 值下降，抑制酶活性，产生熟悉的灼烧感和暂时性肌肉疲劳。该系统在持续 10–90 秒的运动中占据主导。
s in the presence of oxygen. The overall equation for glucose oxidation is: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ~36– ource during endurance activities such as marathon running, distance swimming and cycling.
有氧系统通过在有氧条件下彻底氧化碳水化合物和脂肪，为长时间中低强度运动提供几乎无限的能量。葡萄糖氧化的总反应式为：C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 约 36–38 ATP。脂肪酸产能更多，但需消耗更多氧气。有氧系统是马拉松、长距离游泳和自行车等耐力项目的主要能量来源。
In reality, all three energy systems contribute simultaneously, with the proportion determined by exercise intensity and duration — this is known as the energy continuum. After exercise, excess post-exercise oxygen consumption (EPOC) consists of a fast component restoring ATP/PC stores and a slow component linked to elevated heart rate, temperature and lactate clearance.
实际上，三大供能系统同时参与供能，各自贡献比例取决于运动强度和持续时间，这被称为能量连续统一体。运动后，过量氧耗（EPOC）的快速部分用于恢复 ATP 和 PC 储量，慢速部分则与心率升高、体温偏高及乳酸清除有关。
2. Training Principles and Adaptations | 训练原则与适应
Effective training programmes are built on the principles of specificity, overload, progression, reversibility and tedium. Overload is achieved by manipulating frequency, intensity, time and type — commonly remembered as the FITT principle. Without progressive overload, performance plateaus.
有效的训练计划建立在专项性、超负荷、渐进性、可逆性和防止单调等原则之上。超负荷通过调整频率、强度、时长和类型来实现，即常说的 FITT 原则。若缺乏渐进超负荷，运动表现将停滞不前。
Long-term aerobic training induces significant physiological adaptations. Stroke volume increases due to cardiac hypertrophy, lowering resting heart rate. VO₂ max improves as a result of enhanced cardiac output and greater arteriovenous oxygen difference. At the muscle level, capillary density, mitochondrial numbers and myoglobin content all rise, boosting oxygen extraction and utilisation.
长期有氧训练会引发显著的生理适应。心脏肥大使得每搏输出量增加，安静心率下降。心输出量提高和动静脉氧差增大共同促使最大摄氧量（VO₂ max）提升。在肌肉层面，毛细血管密度、线粒体数目和肌红蛋白含量均增加，从而增强氧气的摄取与利用。
Anaerobic training adaptations include increased resting stores of ATP and PC, greater buffering capacity against lactic acid, and enhanced activity of glycolytic enzymes. This delay fatigue during repeated high-intensity efforts. Periodisation — dividing the training year into macrocycles, mesocycles and microcycles — helps manage workload and peak at the right time.
无氧训练的适应包括静息 ATP 和 PC 储量增加、缓冲乳酸能力增强以及糖酵解酶活性提升。这能延缓高强度反复运动时的疲劳。训练分期——将全年分为大周期、中周期和小周期——有助于合理管理负荷并在恰当时间达到巅峰状态。
3. Sports Nutrition and Ergogenic Aids | 运动营养与能量补充剂
Nutritional strategies directly influence performance and recovery. Carbohydrate loading increases muscle glycogen stores before prolonged endurance events. Protein intake (around 1.2–2.0 g per kg of body mass daily) supports muscle repair and hypertrophy in strength athletes. Adequate hydration is critical; a loss of just 2% body mass as sweat can impair cognitive and physical performance.
营养策略直接影响运动表现和恢复。在长距离耐力赛前进行糖原负荷法可增加肌糖原储量。力量型运动员每日蛋白质摄入约 1.2–2.0 克/千克体重有助于肌肉修复和肥大。充足的水分至关重要；汗水流失仅达体重的 2% 便会损害认知和体能表现。
Ergogenic aids are substances or techniques used to enhance performance. Nutritional aids such as creatine monohydrate increase PC availability, benefiting repeated explosive efforts. Caffeine acts as a central nervous system stimulant, reducing perceived exertion. Pharmacological aids like anabolic steroids and EPO, though effective, are prohibited and carry severe health risks and ethical consequences.
能量补充剂指用于提升表现的物质或方法。营养性补充剂如肌酸一水合物能增加磷酸肌酸供应，有益于反复爆发性运动。咖啡因作为中枢神经兴奋剂可降低主观疲劳感。药物性补充剂例如合成类固醇和促红细胞生成素（EPO），尽管有效，却属于违禁药品，会带来严重的健康风险和伦理后果。
4. Sports Psychology: Confidence and Anxiety | 运动心理学：自信与焦虑
Self-efficacy, a central concept in Bandura's social cognitive theory, refers to an athlete's belief in their ability to succeed in a specific task. It is built through four sources: performance accomplishments (past success), vicarious experience (observing others), verbal persuasion (encouragement from coaches) and emotional arousal (interpretation of physiological states). High self-efficacy improves persistence and performance under pressure.
自我效能是班杜拉社会认知理论的核心概念，指运动员对自己在特定任务中取得成功的能力所持有的信念。它通过四种途径建立：表现成就（过往成功经验）、替代经验（观察他人）、言语劝导（教练的鼓励）和情绪唤醒（对生理状态的理解）。高自我效能有助于提升压力下的坚持性和表现。
Anxiety in sport is often divided into state anxiety (temporary, situation-specific) and trait anxiety (a stable personality disposition). It is further categorised as cognitive anxiety (worry, negative thoughts) and somatic anxiety (physiological responses like increased heart rate). The inverted-U hypothesis suggests optimal arousal for peak performance lies at moderate levels, while the catastrophe model adds that high cognitive anxiety combined with high somatic arousal can trigger a sudden performance drop.
运动焦虑通常分为状态焦虑（临时的、情境性的）和特质焦虑（稳定的人格倾向）。进一步可区分为认知焦虑（忧虑、负面思维）和躯体焦虑（心率加快等生理反应）。倒 U 型假说认为，最佳唤醒水平处于中等程度，表现最佳；而灾难模型进一步指出，高认知焦虑与高躯体唤醒叠加时，可能导致运动表现急剧下滑。
Anxiety management strategies include progressive muscular relaxation, breathing techniques, imagery and goal setting. Imagery, when using all senses, can recreate successful performance scenarios, reducing cognitive anxiety. Goal setting (SMARTER goals) directs attention and builds confidence through achievable stepping stones.
焦虑管理策略包括渐进式肌肉放松、呼吸技巧、意象训练和目标设定。运用多重感官的意象训练能重现成功表现场景，减轻认知焦虑。目标设定（SMARTER 目标）引导注意力，并通过可实现的阶段性目标建立信心。
5. Aggression and Motivation in Sport | 体育中的攻击性与动机
Aggression in sport is defined as behaviour intended to harm another individual. Hostile aggression is driven by anger and aims to cause injury, whereas instrumental aggression is goal-directed (e.g., a hard tackle to regain possession). Theories explaining aggression include the instinct theory (innate drive), frustration-aggression hypothesis (blocked goal leads to aggression), and social learning theory (aggression learned through observation and reinforcement).
体育攻击行为被定义为故意伤害他人的行为。敌意性攻击由愤怒驱动，以造成损伤为目的；工具性攻击则是目标导向的（如为夺回球权而进行凶狠铲断）。解释攻击性的理论包括本能论（先天驱力）、挫折-攻击假说（目标受阻引发攻击）以及社会学习理论（通过观察和强化习得攻击行为）。
Motivation is the direction and intensity of effort. Intrinsic motivation comes from within (enjoyment, mastery), while extrinsic motivation is driven by external rewards (trophies, prize money). Achievement motivation, proposed by Atkinson, combines the need to achieve (Nach) and the need to avoid failure (Naf). High-Nach athletes choose challenging but realistic tasks. Weiner's attribution model explains how causal attributions (ability, effort, luck, task difficulty) affect future motivation and emotion.
动机是努力的方向和强度。内部动机源自内心（乐趣、掌握感），外部动机则由外部奖赏（奖杯、奖金）驱动。阿特金森提出的成就动机综合了追求成功（Nach）和避免失败（Naf）两种需要。高成就动机运动员会选择具有挑战性但现实可行的任务。韦纳的归因模型解释了人们对成败的原因归属（能力、努力、运气、任务难度）如何影响未来动机和情绪。
6. Skill Acquisition: Information Processing | 技能习得：信息加工
Information processing models explain how athletes perceive, interpret and respond to environmental stimuli. Welford's model includes sense organs receiving input, perception translating and making sense of information, a decision-making stage, effector control and feedback. Whiting's model adds a central mechanism and emphasises the role of perception and selective attention in filtering relevant cues from a noisy display.
信息加工模型解释了运动员如何感知、解释和响应环境刺激。韦尔福德模型包括感觉器官接收输入、知觉对信息进行编译和赋予意义、决策阶段、效应器控制和反馈。怀廷模型则增加一个中央机制，并强调知觉与选择性注意在从繁杂的展示背景中筛选相关线索的作用。
Reaction time is the interval between the onset of a stimulus and the start of a response, while response time includes reaction time plus movement time. Hick's Law states that as the number of stimulus–response choices increases, reaction time slows logarithmically. Coaches can reduce reaction time by improving anticipation, simplifying environmental cues and rehearsing motor programmes.
反应时是刺激出现到反应开始之间的时间间隔，而响应时间则包含反应时加上动作时间。希克定律指出，随着刺激-反应选择数的增加，反应时会以对数方式减慢。教练可通过提升预判能力、简化环境线索和反复演练运动程序来缩短反应时。
7. Memory and Feedback in Skill Learning | 技能学习中的记忆与反馈
ers via sense organs and is held briefly in STSS. Selective attention moves relevant information into STM, which has a limited capacity of around 7±2 items and a short duration unless rehearsed. Through chunking and meaningful encoding, skills and knowledge are transferred into LTM, which has unlimited capacity and duration.
记忆系统包括三个储存库：感觉记忆（STSS）、短时记忆（STM）和长时记忆（LTM）。信息经感觉器官进入感觉记忆短暂停留。选择性注意将相关信息转入短时记忆，其容量有限，约为 7±2 个项目，若不加以复述则保留时间很短。通过组块化和有意义编码，技能与知识被转入容量和时间均几乎无限的长时记忆。
Feedback is essential for learning and performance. Intrinsic feedback comes from the body's proprioceptors (e.g., feeling a clean strike in golf), whereas extrinsic feedback is provided by outside sources, such as a coach. Knowledge of results (KR) informs about the outcome, while knowledge of performance (KP) relates to movement technique. Terminal feedback is given after a performance; concurrent feedback is offered during it. For skill acquisition, novices benefit from clear KR and external guidance, but as they become autonomous learners, less feedback promotes self-correction.
反馈对技能学习和表现至关重要。内部反馈来自本体感受器（如高尔夫球手感受到的一次干净击球），外部反馈则由教练等外部来源提供。结果反馈（KR）告知运动结果，表现反馈（KP）则针对动作技术。终末反馈在动作完成后给予，同步反馈则在动作过程中提供。在技能习得阶段，初学者可从明确的结果反馈和外部指导中受益，但随着他们进入自主阶段，减少反馈能促进自我纠错。
8. Sport and Society: Ethics and Deviance | 体育与社会：伦理与越轨行为
Ethical conduct in sport ranges from sportsmanship — fair play, respect for rules and opponents — to gamesmanship, which bends rules without breaking them, and outright deviance, which involves deliberate rule-breaking and anti-social acts. Doping represents a major form of deviance. Athletes may turn to performance-enhancing drugs for reasons including pressure to win, financial gain, national pride or lack of effective testing.
体育中的伦理行为涵盖从体育精神（公平竞争、尊重规则和对手）到竞技诡计（不违反规则却钻空子），直至公然越轨（蓄意违规和反社会行为）。服用兴奋剂是越轨行为的一种主要形式。运动员使用提高成绩的禁药，其动因可能包括获胜压力、经济利益、国家荣誉或检测手段不足。
The World Anti-Doping Agency (WADA) maintains the prohibited list and oversees testing. Sanctions for doping violations include competition bans and loss of medals and records. Broader deviance also includes spectator violence (hooliganism), which can be attributed to factors such as alcohol, group identity and poor social control. Counter-strategies involve stricter laws, stadium design and community engagement programmes.
世界反兴奋剂机构（WADA）负责维护禁药清单并监督检测。兴奋剂违规的处罚包括禁赛、剥夺奖牌和取消纪录。更广泛的越轨行为还包括观众暴力（足球流氓），其原因可归结为酒精、群体认同及社会管控乏力。应对措施包括更严格的法律、体育场设计和社区参与项目。
9. Technology, Media and Commercialisation | 科技、媒体与商业化
The golden triangle of sport, media and sponsorship illustrates how each component supports the others. Media coverage increases sport's visibility, attracting lucrative sponsorship deals; sponsors inject funds that improve facilities and athlete development; sport provides media with compelling content, driving advertising revenue. However, this relationship can also lead to loss of traditional values, scheduling changes to suit broadcasters, and unequal coverage of minority sports.
体育、媒体与赞助的“金三角”反映了三者相互支撑的关系。媒体转播增加了体育的曝光度，吸引丰厚的赞助协议；赞助商注入资金改善设施和运动员发展；体育为媒体提供精彩内容，带动广告收入。然而，这种关系也可能导致传统价值观丧失、赛程迁就转播商以及小众运动报道不足。
Technology influences sport at many levels. Equipment innovations (carbon-fibre bikes, lighter boots) can enhance performance, while decision-review systems (Hawk-Eye, VAR) improve officiating accuracy. Wearable devices and data analytics enable precise monitoring of training load and injury risk. Ethical debates arise over whether technology creates unfair advantages or undermines the human element of sport.
科技在多个层面影响着体育。器材创新（碳纤维自行车、更轻便的足球鞋）可提升运动表现，而决策复审系统（鹰眼、视频助理裁判）提高了裁判准确性。可穿戴设备和数据分析使得训练负荷与伤风险的精准监控成为可能。伦理争议围绕着科技是否制造了不公平优势或削弱了体育的人为因素。
10. Biomechanics: Projectile Motion and Newton’s Laws | 生物力学：抛体运动与牛顿定律
Newton' n) states that force equals mass multiplied by acceleration (F = ma); the greater the force applied to an object, the greater its acceleration. Newton's Third Law (action– athlete exerts force backward against the blocks and the blocks push the athlete forward.
牛顿第一定律（惯性）解释了为何曲棍球在受力前保持静止，以及跳水运动员为何能在空中继续飞行。第二定律（加速度）指出，力等于质量乘以加速度（F = ma）；施加于物体的力越大，其加速度越大。牛顿第三定律（作用力与反作用力）是起跑蹬离的基础——运动员对起跑器施加向后的力，起跑器则向前推动运动员。
Projectile motion describes the flight path of objects after release, determined by velocity, angle and height of release, air resistance and gravity. For a given speed, the optimal angle for maximum horizontal distance is 45° when release and landing heights are equal. However, in sports like shot put, the release height is above the landing height, so the optimal angle is slightly below 45°. In badminton, higher release height and steeper angle create a better drop shot trajectory.
抛体运动描述了物体出手后的飞行轨迹，由出手速度、出手角度和出手高度、空气阻力及重力共同决定。在投掷与落点高度相同的情况下，实现最大水平距离的最优出手角为 45°。但像铅球这样的项目，出手高度高于落点，最优角度略低于 45°。在羽毛球中，较高的击球点和更陡的角度则能打出更佳的小球弧线。
Levers in the human body alter the speed and force of movements. A first-class lever (e.g., neck extension) has the fulcrum between effort and load. Second-class levers (e.g., ankle plantar flexion in a ballet relevé) have the load between fulcrum and effort, offering mechanical advantage. Third-class levers (e.g., bicep curl) place the effort between fulcrum and load, allowing a large range of motion at speed but at a mechanical disadvantage.
人体中的杠杆可改变运动的速度和力。第一类杠杆（如颈部后仰）支点位于力点与阻力点之间。第二类杠杆（如芭蕾立足尖时踝关节跖屈）阻力点位于支点与力点之间，可产生机械利益。第三类杠杆（如肱二头肌屈肘）力点位于支点与阻力点之间，虽处机械劣势，却能获得速度和较大的运动范围。
