1. Health, Fitness and Well-being | 健康、体能和幸福

Health is defined as a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity. Fitness refers to the ability to meet the demands of the environment. Well-being is the combination of feeling good and functioning well in everyday life.

健康被定义为身体、心理和社会完全健康的状态，而不仅仅是没有疾病或虚弱。体能是指满足环境需求的能力。幸福感是感觉良好与日常运作良好的结合。

Physical health involves all body systems working efficiently; this can be improved through regular exercise, a balanced diet and adequate rest. Emotional health means being able to manage emotions, cope with stress and maintain a positive self-image. Social health is about building satisfying relationships and feeling a sense of belonging within a community.

身体健康体现在所有身体系统高效运作，可通过定期锻炼、均衡饮食和充足休息来改善。情绪健康指能够管理情绪、应对压力并保持积极的自我形象。社交健康指建立满意的人际关系并在社群中有归属感。

Leading a physically active lifestyle reduces the risk of chronic diseases such as obesity, type 2 diabetes and cardiovascular conditions. It also boosts self-esteem, enhances mood and promotes better sleep, all of which contribute positively to overall well-being.

积极运动的生活方式可降低肥胖、2 型糖尿病和心血管疾病等慢性病风险。它还能提升自尊、改善情绪并促进更好的睡眠，这些都对整体幸福感有积极作用。

2. The Skeletal System | 骨骼系统

The human skeleton has five main functions: support, holding the body upright and giving it shape; protection of vital organs, such as the cranium protecting the brain; movement by providing surfaces for muscle attachment via tendons; mineral storage, particularly calcium and phosphorus; and blood cell production (haematopoiesis) in the bone marrow of long bones and the pelvis.

人体骨骼有五项主要功能：支持，保持身体直立并赋予其形状；保护重要器官，如颅骨保护大脑；运动，通过为肌腱附着提供表面；矿物质储存，尤其是钙和磷；以及在长骨和骨盆的骨髓中制造血细胞（造血）。

Key bones include the cranium, clavicle, scapula, sternum, ribs, humerus, radius, ulna, carpals, metacarpals, phalanges, vertebrae, pelvis, femur, patella, tibia, fibula, tarsals and metatarsals. Joints are classified by their range of movement: synovial (freely movable) joints include ball-and-socket (shoulder and hip), hinge (elbow and knee), pivot (neck), gliding (wrist and ankle) and saddle (thumb).

关键骨骼包括颅骨、锁骨、肩胛骨、胸骨、肋骨、肱骨、桡骨、尺骨、腕骨、掌骨、指骨、椎骨、骨盆、股骨、髌骨、胫骨、腓骨、跗骨和跖骨。关节按其活动范围分类：滑膜（自由活动）关节包括球窝关节（肩和髋）、铰链关节（肘和膝）、枢轴关节（颈）、滑动关节（腕和踝）和鞍状关节（拇指）。

Movement terms describe the action at a joint: flexion (decreasing the angle), extension (increasing the angle), abduction (moving away from the body’s midline), adduction (moving towards the midline), rotation (turning around an axis), circumduction (circular movement), plantar flexion (pointing the toes) and dorsiflexion (lifting the toes upwards).

运动术语描述关节处的动作：屈曲（减小角度）、伸展（增大角度）、外展（远离身体中线）、内收（靠近身体中线）、旋转（绕轴转动）、环转（圆形运动）、跖屈（脚尖下压）和背屈（脚尖上翘）。

3. The Muscular System | 肌肉系统

Major voluntary muscles you must know include the deltoid, trapezius, pectorals, biceps, triceps, abdominals, latissimus dorsi, gluteals, quadriceps, hamstrings and gastrocnemius. These muscles work in antagonistic pairs to produce coordinated movement: while one muscle contracts (the agonist), the opposite muscle relaxes (the antagonist). For example, during elbow flexion, the biceps acts as the agonist and the triceps as the antagonist.

你必须掌握的主要随意肌包括三角肌、斜方肌、胸肌、肱二头肌、肱三头肌、腹肌、背阔肌、臀肌、股四头肌、腘绳肌和腓肠肌。这些肌肉以拮抗肌对的形式协调运动：一块肌肉收缩（主动肌），对侧肌肉放松（拮抗肌）。例如，肘部屈曲时，肱二头肌为主动肌，肱三头肌为拮抗肌。

Muscle contractions are categorised as isotonic (where the muscle changes length) or isometric (where the muscle stays the same length while generating tension). Isotonic contractions are further divided into concentric (muscle shortens under tension) and eccentric (muscle lengthens under tension). A fixator muscle stabilises the origin of the agonist to allow efficient movement.

肌肉收缩分为等张收缩（肌肉长度改变）和等长收缩（肌肉保持长度不变但产生张力）。等张收缩又分为向心收缩（肌肉在张力下缩短）和离心收缩（肌肉在张力下伸长）。固定肌稳定主动肌的起点，以帮助高效运动。

4. The Cardiovascular System | 心血管系统

The cardiovascular system consists of the heart, blood vessels and blood. The heart has four chambers: two atria and two ventricles, separated by valves that prevent backflow. Blood is pumped through arteries (carrying blood away from the heart), capillaries (where gaseous exchange occurs) and veins (returning blood to the heart). Blood is composed of plasma, red blood cells (which carry oxygen), white blood cells and platelets.

心血管系统由心脏、血管和血液组成。心脏有四个腔室：两个心房和两个心室，由防止血液回流的瓣膜分隔。血液流经动脉（将血液带离心脏）、毛细血管（进行气体交换）和静脉（将血液送回心脏）。血液由血浆、红细胞（携带氧气）、白细胞和血小板组成。

Heart rate (HR) × Stroke volume (SV) = Cardiac output (Q)

心率 (HR) × 每搏输出量 (SV) = 心输出量 (Q)

During exercise, heart rate increases to deliver more oxygen to working muscles. Stroke volume also rises due to stronger ventricular contractions. Maximum heart rate can be estimated using the formula HRₘₐₓ ≈ 220 − age. A trained athlete typically has a lower resting heart rate and a higher stroke volume, making the heart more efficient.

运动时，心率增加以满足肌肉对氧气的需求。每搏输出量也因心室收缩更有力而升高。最大心率可用公式 HRₘₐₓ ≈ 220 − 年龄来估算。训练有素的运动员通常静息心率较低，每搏输出量较高，心脏效率更高。

5. The Respiratory System | 呼吸系统

The respiratory system brings oxygen into the body and removes carbon dioxide. Air passes through the nose or mouth, travels down the trachea, into the bronchi and bronchioles, and finally reaches the alveoli, where gaseous exchange takes place. Oxygen diffuses from the alveoli into the capillaries, while carbon dioxide moves in the opposite direction.

呼吸系统将氧气带入体内并排出二氧化碳。空气经鼻腔或口腔进入，沿气管下行，通过支气管和细支气管，最终到达肺泡，在肺泡进行气体交换。氧气从肺泡扩散到毛细血管，二氧化碳则反向移动。

Breathing involves the intercostal muscles and the diaphragm. During inspiration, the diaphragm contracts and flattens, and the external intercostal muscles lift the ribcage up and out, increasing thoracic volume and drawing air into the lungs. During expiration, these muscles relax, the diaphragm domes upwards and the ribcage lowers, pushing air out. At rest, expiration is passive, but during exercise it becomes active, using internal intercostal and abdominal muscles.

呼吸涉及肋间肌和膈肌。吸气时，膈肌收缩变平，外肋间肌将胸廓上提外扩，胸腔容积增大，空气进入肺部。呼气时，这些肌肉放松，膈肌向上拱起，胸廓下降，空气排出。安静时呼气是被动的，但在运动中变为主动，需要内肋间肌和腹肌的参与。

Key lung volumes include tidal volume (the amount of air inhaled and exhaled per breath at rest) and vital capacity (the maximum amount of air that can be exhaled after a maximum inhalation). Both increase during exercise to support the higher demand for oxygen.

关键肺容量包括潮气量（每次安静呼吸吸入和呼出的气体量）和肺活量（最大吸气后能呼出的最大气体量）。运动中两者都会增加，以满足更高的氧气需求。

6. Components of Fitness | 体能组成要素

Fitness components are divided into health-related and skill-related categories. The table below outlines the key components relevant to CCEA GCSE Physical Education.

体能要素分为健康相关和技能相关两大类。下表列出 CCEA GCSE 体育中需掌握的关键要素。

Health-related (English)	健康相关 (中文)	Skill-related (English)	技能相关 (中文)
Cardiovascular endurance	心血管耐力	Agility	敏捷性
Muscular strength	肌肉力量	Balance	平衡
Muscular endurance	肌肉耐力	Coordination	协调性
Flexibility	柔韧性	Power	爆发力
Body composition	身体成分	Reaction time	反应时
		Speed	速度

Health-related components are fundamental to overall health and everyday function. Skill-related components are more specific to performance in sports and activities. For example, a gymnast requires exceptional balance and coordination, while a sprinter relies heavily on speed and power.

健康相关要素对整体健康和日常功能至关重要。技能相关要素则更针对运动表现。例如
