掌握 AS 体育学科的专门术语是考试成功的关键。本指南将解剖学、生理学、生物力学、技能习得、运动心理学和社会文化研究中的关键术语分解成易于记忆的片段。每个部分都将英文定义与中文对应配对，帮助你建立双语基础，并在考试压力下迅速回忆术语。
1. Fundamental Anatomical Terms | 基础解剖学术语
The anatomical position is the universal reference point: the body stands upright, facing forward, with arms at the sides and palms facing forward. From this position, all directional terms are defined.
解剖学姿势是通用的参考点：身体直立，面向前方，手臂置于身体两侧，掌心向前。所有方向术语都基于这一姿势定义。
Directional terms include anterior (front), posterior (back), medial (toward the midline), lateral (away from the midline), proximal (closer to the trunk), distal (further from the trunk), superior (above), and inferior (below). These describe the location of structures relative to each other.
方向术语包括 anterior（前）、posterior（后）、medial（靠近中线）、lateral（远离中线）、proximal（近躯干端）、distal（远躯干端）、superior（上方）和 inferior（下方）。它们描述结构之间的相对位置。
The body can be divided into three planes of motion: the sagittal plane (divides left and right, allowing flexion and extension), the frontal plane (divides front and back, allowing abduction and adduction), and the transverse plane (divides top and bottom, allowing rotation and horizontal movement).
身体可分为三个运动平面：矢状面（分为左右，允许屈曲和伸展）、冠状面（分为前后，允许外展和内收）以及水平面（分为上下，允许旋转和水平运动）。
2. Joint Movements and Muscle Actions | 关节运动与肌肉动作
Flexion decreases the angle at a joint (e.g., bending the elbow), while extension increases it (e.g., straightening the knee). Abduction moves a limb away from the midline, and adduction brings it back toward the body.
屈曲减小关节角度（例如弯肘），而伸展增加角度（例如伸直膝盖）。外展将肢体移离中线，内收将其拉回身体。
Specific ankle movements are plantar flexion (pointing toes down) and dorsiflexion (pulling toes up). Rotation occurs around the longitudinal axis of a bone, and circumduction is a cone-shaped movement combining flexion, extension, abduction, and adduction.
脚踝特有的运动是跖屈（脚尖下压）和背屈（脚尖上抬）。旋转绕骨的长轴进行，而环转是结合屈、伸、外展和内收的锥形运动。
The agonist (prime mover) is the muscle responsible for producing movement; the antagonist opposes the agonist and helps control the motion. Contractions can be isotonic (concentric: muscle shortens under tension; eccentric: muscle lengthens under tension) or isometric (muscle contracts without changing length).
主动肌（原动肌）是产生运动的主要肌肉；拮抗肌与主动肌作用相反并帮助控制动作。收缩可分为等张收缩（向心收缩：肌肉在紧张下缩短；离心收缩：肌肉在紧张下伸长）或等长收缩（肌肉收缩但长度不变）。
3. Cardiovascular and Respiratory System Terms | 心血管与呼吸系统术语
Heart rate (HR) is the number of beats per minute. Stroke volume (SV) is the amount of blood ejected by the left ventricle per beat. Cardiac output (Q) = HR x SV and represents the total blood flow per minute.
心率 (HR) 是每分钟心跳次数。每搏输出量 (SV) 是左心室每次搏动泵出的血液量。心输出量 (Q) = 心率 x 每搏输出量，代表每分钟总血流量。
In the respiratory system, tidal volume (TV) is the air inhaled or exhaled per normal breath. Vital capacity is the maximum air exhaled after a maximum inhalation. Minute ventilation (VE) = tidal volume x breathing rate.
在呼吸系统中，潮气量 (TV) 是每次正常呼吸吸入或呼出的气量。肺活量 是最大吸气后能呼出的最大气量。每分通气量 (VE) = 潮气量 x 呼吸频率。
VO₂ max is the maximum volume of oxygen the body can utilise per minute per kilogram of body weight; it is the gold standard measure of aerobic capacity. EPOC (Excess Post-exercise Oxygen Consumption), formerly called oxygen debt, refers to the elevated oxygen intake after exercise to restore the body to its resting state.
最大摄氧量 (VO₂ max) 是身体每分钟每千克体重能利用的最大氧气量，是有氧能力的黄金标准测量值。运动后过量氧耗 (EPOC)（以前称为氧债）指运动后为恢复身体至静息状态而增加的摄氧量。
4. Biomechanics Essentials | 生物力学要点术语
Force is any push or pull that changes the state of motion of an object (measured in newtons, N). Mass is the quantity of matter (kg), while weight is the force due to gravity on that mass. Inertia is the resistance of an object to changes in its motion; Newton’s First Law states that an object remains at rest or in uniform motion unless acted upon by an external force.
力是任何改变物体运动状态的推拉作用（以牛顿 N 为单位）。质量是物质的量 (kg)，而重量是重力作用于该质量的力。惯性是物体抵抗运动状态变化的性质；牛顿第一定律指出物体将保持静止或匀速直线运动，除非受到外力作用。
Newton’s Second Law: Force = mass x acceleration (F = ma). Newton’s Third Law: For every action there is an equal and opposite reaction. Momentum = mass x velocity. The summation of forces principle explains how sequential body segment action generates maximum force, as in a tennis serve or javelin throw.
牛顿第二定律：力 = 质量 x 加速度 (F=ma)。牛顿第三定律：每个作用力都有一个大小相等、方向相反的反作用力。动量 = 质量 x 速度。力的总和原理说明身体各环节依次发力可以产生最大力量，如网球发球或标枪投掷。
Levers are classified into three classes. A first-class lever has the fulcrum between effort and load (e.g., neck joint). A second-class lever has the load between fulcrum and effort (e.g., ankle during plantar flexion – rare in body). A third-class lever has effort between fulcrum and load (e.g., elbow joint). Most body levers are third class, favouring speed and range of motion over force.
杠杆分为三类。一类杠杆支点在力点和阻力点之间（如颈关节）。二类杠杆阻力点在支点和力点之间（如跖屈时的踝关节—身体中少见）。三类杠杆力点在支点和阻力点之间（如肘关节）。身体中大多数杠杆为三类杠杆，以速度和运动范围换取力量优势。
Centre of mass is the point where all body mass is concentrated; stability depends on a low centre of mass, wide base of support, and position of the line of gravity within the base.
重心是所有身体质量集中的点；稳定性取决于较低的重心、宽阔的支撑面以及重力线落在支撑面内。
5. Motor Skills and Classification | 动作技能与分类
A skill is the learned ability to bring about a predetermined result with maximum certainty and minimum outlay of time and energy. An ability is an inherited, stable trait that underpins skill performance, such as hand–eye coordination. Technique is the method used to perform a particular skill.
技能是经过学习而获得的、能在最大确定性和最少时间与能量消耗下达成预定结果的能力。能力是遗传的、稳定的支撑技能表现的特性，如手眼协调。技术是执行某一特定技能所用的方法。
Skills can be classified on several continua: gross–fine (large-muscle vs. small-muscle), open–closed (affected by environment vs. predictable), discrete–serial–continuous (clear beginning and end, a series of discrete skills, or no distinct start/stop), self-paced–externally-paced (performer controls timing vs. environment dictates), and simple–complex (few sub-routines and little decision-making vs. many sub-routines and high cognitive demand).
技能可在多个连续体上分类：粗大—精细（大肌肉参与 vs 小肌肉参与）、开放—闭锁（受环境影响 vs 可预测）、分立—序列—连续（有明确起点和终点、一系列分立技能、或无清晰始终）、自我节奏—外部节奏（执行者控制时机 vs 环境决定）、以及简单—复杂（子程序少且决策少 vs 子程序多且认知要求高）。
6. Learning and Performance Terminology | 学习与表现术语
The three stages of learning are: cognitive (beginner tries to understand the task; many errors, needs demonstrations), associative (performer practices and refines; fewer errors, longer duration), and autonomous (skill is automatic; can focus on tactics and environment).
学习的三个阶段是：认知阶段（初学者尝试理解任务；错误多，需要示范）、联结阶段（执行者练习并细化；错误减少，持续时间长）和自主阶段（技能自动化；可专注于战术和环境）。
Guidance types include visual (watching demonstrations), verbal (instruction and cues), manual (physical support, e.g., a coach holding a limb), and mechanical (using apparatus). Each is more effective at different learning stages.
指导类型包括视觉指导（观看示范）、语言指导（指令和提示）、手法指导（身体支持，如教练扶住肢体）和器械指导（使用器械）。不同学习阶段各自的有效性不同。
Feedback can be intrinsic (from the performer’s own sensory systems) or extrinsic/augmented (from an outside source). It can also be knowledge of results (outcome of the movement, e.g., goal scored) or knowledge of performance (quality of the movement, e.g., technique analysis).
反馈可分为内部反馈（来自执行者自身的感觉系统）或外部/增强反馈（来自外部来源）。也可以是结果知识（运动的结果，如进球）或表现知识（动作质量，如技术分析）。
Transfer of learning describes how previous learning affects new learning: positive transfer helps, negative transfer hinders, proactive transfer influences a future skill, retroactive transfer affects a previously learned skill. Bilateral transfer refers to skill transfer from one limb to the other.
学习迁移指先前学习如何影响新学习：正迁移有帮助，负迁移有阻碍，前摄迁移影响未来技能，倒摄迁移影响先前已学技能。双侧迁移指技能从一侧肢体转移到另一侧。
7. Sports Psychology Key Concepts | 运动心理学核心概念
Arousal is the physiological and psychological state of readiness. The Drive Theory (Hull) proposes a linear relationship between arousal and performance; more arousal means better performance of well-learned skills. The Inverted-U Hypothesis (Yerkes & Dodson) suggests that performance improves as arousal increases up to an optimal point, then declines. Catastrophe Theory (Fazey & Hardy) adds that when cognitive anxiety is high, performance may plummet suddenly rather than gradually.
唤醒是生理和心理的准备状态。驱力理论（赫尔）提出唤醒与表现呈线性关系；对熟练技能而言，唤醒越高表现越好。倒U型假说（耶克斯-道森）认为随唤醒增加，表现提升至最佳点后下降。突变理论（法齐与哈代）补充道，当认知焦虑高时，表现可能骤然崩溃而非逐渐下降。
Anxiety can be cognitive (worry, negative thoughts) or somatic (physiological symptoms like increased heart rate or sweating). Self-efficacy (Bandura) is the belief in one’s ability to succeed in specific situations; it influences effort and persistence. Motivation may be intrinsic (inner drive) or extrinsic (external rewards).
焦虑可为认知焦虑（担忧、消极想法）或躯体焦虑（生理症状如心率加快、出汗）。自我效能（班杜拉）是对自己在特定情境下成功能力的信念；影响努力和坚持度。动机可以是内部的（内在驱动力）或外部的（外部奖励）。
Social facilitation occurs when the presence of others improves performance on simple or well-learned tasks, but can cause inhibition on complex tasks due to evaluation apprehension. Group cohesion refers to the forces that bind a group together; task cohesion (commitment to shared goals) is crucial for team success.
社会促进指他人在场能提高简单或熟练任务的表现，但对复杂任务可能因评价恐惧而导致抑制。群体凝聚力指维系群体的力量；任务凝聚力（对共同目标的承诺）对团队成功至关重要。
8. Training Methods and Fitness Components | 训练方法与体能要素
Health-related fitness components include aerobic capacity (cardiorespiratory endurance), muscular endurance, muscular strength, flexibility, and body composition. Skill-related fitness components include agility, balance, coordination, power, reaction time, and speed.
健康相关体适能要素包括有氧能力（心肺耐力）、肌肉耐力、肌肉力量、柔韧性和身体成分。技能相关体适能要素包括灵敏性、平衡、协调性、爆发力、反应时间和速度。
Common training methods: Continuous training (steady-state aerobic exercise), Fartlek training (speed play, varying pace), Interval training (periods of work and recovery), Circuit training (stations of different exercises), Weight training (resistance), and Plyometrics (explosive bounding and jumping).
常见训练方法：持续训练（稳态有氧运动）、法特莱克训练（速度游戏，变换速度）、间歇训练（工作与恢复交替）、循环训练（不同练习站的轮转）、负重训练（抗阻训练）和增强式训练（爆发性跳跃和跨跳）。
The FITT principle guides overload: Frequency, Intensity, Time, Type. The training principles SPORT (Specificity, Progression, Overload, Reversibility, Tedium) must be applied to ensure adaptations and avoid plateaus or reversibility.
FITT 原则指导超负荷：频度、强度、时间和类型。训练原则 SPORT（专项性、渐进性、超负荷、可逆性、枯燥性）必须应用以保证适应并避免平台期或退步。
9. Nutrition and Energy Systems | 营养与能量系统
Macronutrients – carbohydrates (primary fuel for high-intensity exercise), fats (fuel
