1. Anatomical Position, Planes and Axes | 解剖学姿势、平面与轴
Anatomical Position: The standard frame of reference: body upright, facing forward, feet parallel, arms at the sides with palms facing anteriorly. Every directional term assumes this stance. Tip: Imagine a proud statue; palms forward like holding a bowl.
解剖学姿势：标准的参考框架：身体直立、面向前、双脚平行、手臂垂于体侧且掌心朝前。一切方位术语都以此为基础。记忆技巧：想象一尊骄傲的雕像，掌心向前仿佛托着一只碗。
Sagittal Plane: A vertical plane dividing the body into left and right portions. Flexion and extension happen here. Tip: 'Sagittal' sounds like 'sag', which you see from the side – the plane itself slices sideways but produces left-right halves; picture an archer's arrow shooting straight forward along the sagittal plane.
矢状面：将身体分为左右两部分的垂直平面。屈、伸动作发生在此平面上。记忆技巧：'Sagittal' 音近 'sag'（下垂），矢状缝把颅骨分成左右，想象一支箭从前向后直射，代表矢状面的走向。
Frontal (Coronal) Plane: Divides the body into anterior and posterior sections. Abduction and adduction occur here. Tip: A crown (corona) sits on the forehead; the frontal plane passes through the crown, splitting front from back.
额状面（冠状面）：将身体分为前后两部分的垂直平面。外展和内收动作在此平面进行。记忆技巧：'Coronal' 音近 'crown'（皇冠），皇冠戴在额部前方，额状面沿冠切面切开，分出前与后。
Transverse (Horizontal) Plane: Splits the body into superior and inferior segments. Rotation movements like a golf swing happen transversely. Tip: 'Transverse' shares the root with 'transatlantic' – crossing the body horizontally.
水平面（横切面）：将身体分为上下两部分的水平平面。旋转类动作如高尔夫挥杆在水平面上发生。记忆技巧：'Transverse' 词根意为'横跨'，像横渡大西洋一样横穿身体。
2. Joint Actions and Movement Terminology | 关节动作与运动术语
Flexion: Decreasing the angle at a joint, e.g. bending the elbow. Tip: Think of 'flexing' a muscle and making the angle smaller – a flexed bicep closes the elbow joint.
屈：减小关节角度，例如弯肘。记忆技巧：'Flex' 让你想到弯起手臂秀肌肉，肘关节角度随之变小。
Extension: Increasing the angle, returning to anatomical position or beyond. Tip: 'Ex-tension' means expanding the angle; a dancer extending a leg opens the hip joint.
伸：增大关节角度，回到解剖学姿势甚至超过。记忆技巧：'Ex-tension' 中的 'ex' 指向外伸展，舞者后伸腿时髋角增大。
Abduction: Moving a limb away from the midline. Tip: 'Ab-duction' – to abduct is to take away, just like the alien abduction takes you away from home; the limb is taken away from the body's midline.
外展：肢体远离身体中线的动作。记忆技巧：'Ab-duction' 中的 'ab' 表示远离，如同外星人将你绑架(abduct)带走，肢体也被带离中线。
Adduction: Bringing the limb back towards the midline. Tip: 'Ad-duction' – to add back to the body; hug yourself to adduct the arms.
内收：肢体回归中线的动作。记忆技巧：'Ad-duction' 中的 'ad' 表示添加、朝向，给自己一个拥抱就是手臂内收。

主动肌（原动肌）：直接负责产生某一动作的肌肉。例如肘屈时，肱二头肌是主动肌。记忆技巧：'Agonist' 音似 'agony'（痛苦），它承担主要收缩工作，承受张力。
Antagonist: to : The muscle that opposes the agonist, relaxing and lengthening to permit movement. During elbow flexion, the triceps brachii acts as the antagonist. Tip: 'Antagonist' = anti-agonist; it opposes the action.
拮抗肌：与主动肌作用相反的肌肉，通过放松和拉长来允许动作发生。肘屈时，肱三头肌即为拮抗肌。记忆技巧：'Antagonist' = 反主动肌，对抗作用。
Isotonic Contraction (Concentric): Muscle shortens under tension, e.g. upward phase of a bicep curl. Tip: 'Concentric' – central area gets closer, muscle bellies come together.
等张收缩（向心收缩）：肌肉在张力下缩短，例如肱二头弯举上举阶段。记忆技巧：'Concentric' 联想到中心靠拢，肌腹相互靠近。
Eccentric Contraction: Muscle lengthens while under tension, controlling the downward phase. Tip: 'Eccentric' ded length; the muscle gets longer despite tension, like letting down a heavy book slowly.
离心收缩：肌肉在张力下被拉长，控制动作的放下阶段。记忆技巧：'Eccentric' 里藏着 'extend'，肌肉虽用力却在拉长，如同缓慢放下重物。
Isometric Contraction: Muscle tension develops but length remains unchanged, e.g. holding a plank. Tip: 'Iso-' = equal, 'metric' = length; equal length throughout.
等长收缩：肌肉产生张力但长度恒定，如平板支撑。记忆技巧：'Iso-' 意为相同，'metric' 指长度，全程长度相等。
4. Cardiovascular and Respiratory Vocabulary | 心血管与呼吸术语
Heart Rate (HR): Number of cardiac cycles per minute (bpm). Resting HR for a trained athlete may drop below 50 bpm. Tip: HR is the beat clock; lower resting HR often indicates greater cardiac efficiency.

Stroke Volume (SV): Volume of blood ejected by the left ventricle per beat. Increases during exercise due to greater venous return and myocardial contractility. Tip: 'Stroke' means one pump; bigger stroke volume means more blood moved per heartbeat.
每搏输出量 (SV):左心室每次搏动泵出的血量。运动时因静脉回流量和心肌收缩力增强而增大。记忆技巧：'Stroke' 是一泵，每搏输出量越大，每次心跳输出的血液越多。
Cardiac Output (Q): rcise, Q can rise from 5 to over 20 L·min⁻¹. Tip: Remember Q = heart rate × stroke volume; 'Q' for quantity pumped.
心输出量 (Q):心率×每搏输出量，代表每分钟泵出的血量(升/分钟)。剧烈运动时，Q可从5升至20升/分钟以上。公式记忆：Q = HR × SV，Q就是泵出的总量。

Moment of Inertia: Resistance of a body to change its rotational motion, depending on mass distribution about the axis. Tucked diving position reduces moment of inertia, allowing faster somersaults. Tip: Inertia resists change; mass far from axis gives high resistance; bring mass close to axis to spin faster.
转动惯量：物体抵抗旋转状态变化的性质，取决于质量对轴的分布。抱膝姿势降低转动惯量，使翻腾更快。记忆技巧：转动惯量抗拒改变，质量离轴越远阻力越大；靠近轴心就转得更快。
Bernoulli's Principle: r : Faster fluid flow creates lower pressure. Applied to lift in discus and spin on footballs. Tip: 'Bernoulli = blow faster, pressure drops' – think of an aeroplane wing.
