1. Health-Related Components of Fitness | 健康相关体能要素

Health-related fitness refers to the aspects of physical fitness that contribute to overall health and well-being. The five key components are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition.

健康相关体能是指对整体健康和幸福感有贡献的体能方面。五个关键要素是心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。

Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to working muscles during sustained activity. 心血管耐力是心脏、肺和血管在持续活动中向工作肌肉输送氧气的能力。
Muscular strength is the maximum force a muscle or muscle group can exert in a single effort. 肌肉力量是一块肌肉或肌群单次发力所能产生的最大力量。
Muscular endurance is the ability of a muscle or muscle group to perform repeated contractions over time without fatigue. 肌肉耐力是肌肉或肌群在长时间内重复收缩而不疲劳的能力。
Flexibility is the range of motion available at a joint. 柔韧性是关节可活动的范围。
Body composition refers to the proportion of fat mass to fat-free mass (muscle, bone, water) in the body. 身体成分指体内脂肪质量与去脂质量（肌肉、骨骼、水分）的比例。

2. Skill-Related Components of Fitness | 技能相关体能要素

Skill-related fitness components are more closely linked to sports performance. The six components are agility, balance, coordination, power, reaction time and speed.

技能相关体能要素与运动表现的关系更紧密。六个要素分别是灵敏性、平衡、协调、爆发力、反应时间和速度。

Agility – the ability to change direction quickly while maintaining control. 灵敏性 – 快速改变方向同时保持身体控制的能力。
Balance – the ability to keep the body’s centre of mass over a base of support, whether static or dynamic. 平衡 – 在静止或运动中保持身体重心在支撑面内的能力。
Coordination – the smooth and efficient integration of body parts to produce a desired movement. 协调 – 身体各部位顺畅高效地配合完成动作的能力。
Power – the product of strength and speed; the ability to exert maximum force in a short time. 爆发力 – 力量与速度的乘积；在短时间内发挥最大力量的能力。
Reaction time – the time taken to respond to a stimulus. 反应时间 – 对刺激做出反应所需的时间。
Speed – the ability to move all or part of the body quickly. 速度 – 快速移动身体全部或部分的能力。

3. Principles of Training (SPORT/FITT) | 训练原则 (SPORT/FITT)

To improve fitness effectively, training must follow the SPORT and FITT principles. SPORT stands for Specificity, Progression, Overload, Reversibility and Tedium.

要有效提升体能，训练必须遵循 SPORT 和 FITT 原则。SPORT 代表针对性、渐进性、超负荷、可逆性和乏味性。

Specificity – training must be relevant to the sport or goal. 针对性 – 训练必须与运动项目或目标相关。
Progression – gradually increasing the intensity/duration of training as the body adapts. 渐进性 – 随着身体适应，逐步增加训练强度或持续时间。
Overload – working the body harder than normal to cause adaptation. 超负荷 – 让身体承受比平常更大的负荷以产生适应。
Reversibility – fitness gains are lost when training stops or decreases significantly. 可逆性 – 停止或大幅减少训练时，体能提升会丢失。
Tedium – training should be varied to avoid boredom and maintain motivation. 乏味性 – 训练应多样化以避免枯燥、保持积极性。

The FITT principle helps apply overload: Frequency, Intensity, Time and Type.

FITT 原则有助于实施超负荷：频率、强度、时间和类型。

Frequency (how often)	频率（多久一次）
Intensity (how hard)	强度（多费力）
Time (how long)	时间（持续多久）
Type (mode of exercise)	类型（运动方式）

4. Methods of Training | 训练方法

Different training methods develop specific fitness components. Common methods include continuous, interval, circuit, weight, Fartlek and flexibility training.

不同的训练方法发展特定的体能要素。常见方法包括持续训练、间歇训练、循环训练、负重训练、法特莱克训练和柔韧性训练。

Continuous training – steady, moderate-intensity exercise for at least 20 minutes, e.g. jogging, cycling; develops cardiovascular endurance. 持续训练 – 稳定、中等强度的运动至少20分钟，如慢跑、骑行；发展心血管耐力。
Interval training – alternating periods of high-intensity work and rest/low-intensity recovery; improves speed, power and endurance. 间歇训练 – 高强度运动与休息/低强度恢复交替；提高速度、爆发力和耐力。
Circuit training – a series of exercise stations performed with minimal rest; can target both health- and skill-related fitness. 循环训练 – 一系列练习站，中间休息很少；可同时针对健康与技能相关体能。
Weight training – using free weights or machines to develop muscular strength and endurance. 负重训练 – 使用自由重量或器械发展肌肉力量与耐力。
Fartlek training – ‘speed play’; continuous running with random bursts of speed; good for game sports. 法特莱克训练 – ‘变速跑’；持续跑步中随机穿插冲刺；适合球类等游戏性运动。
Flexibility training – static, dynamic or PNF stretching to increase range of motion. 柔韧性训练 – 静态、动态或 PNF 拉伸，增加关节活动范围。

5. Skeletal System Overview | 骨骼系统概述

The skeleton provides support, protection, movement, mineral storage and blood cell production. Key bones and their functions link directly to physical performance.

骨骼提供支撑、保护、运动、矿物质储存和血细胞生成。关键骨骼及其功能与运动表现直接相关。

Major bones students should identify include: cranium, clavicle, scapula, humerus, radius, ulna, vertebral column, pelvis, femur, patella, tibia, fibula, and the bones of the hands and feet.

学生应能识别的主要骨骼包括：颅骨、锁骨、肩胛骨、肱骨、桡骨、尺骨、脊柱、骨盆、股骨、髌骨、胫骨、腓骨以及手部与足部骨骼。

Functions: The skeleton acts as a framework (support), shields vital organs (protection), provides levers and attachment points for muscles (movement), stores calcium and phosphorus, and produces blood cells in bone marrow.

功能： 骨骼作为框架（支撑），保护重要器官（保护），为肌肉提供杠杆和附着点（运动），储存钙和磷，并在骨髓中制造血细胞。

6. Muscular System & Movements | 肌肉系统与运动

Muscles contract to pull on bones, creating movement at joints. Understanding major muscles and their actions is essential for analysing sports movements and preventing injury.

肌肉收缩牵拉骨骼，在关节处产生运动。了解主要肌肉及其作用对于分析运动动作和预防损伤至关重要。

Key muscles: deltoid, pectorals, biceps, triceps, abdominals, quadriceps, hamstrings, gluteals, gastrocnemius and latissimus dorsi.

主要肌肉：三角肌、胸肌、肱二头肌、肱三头肌、腹肌、股四头肌、腘绳肌、臀肌、腓肠肌和背阔肌。

Movement types at joints include flexion, extension, abduction, adduction, rotation, and more. For example, the biceps cause elbow flexion, while the triceps cause elbow extension. Antagonistic pairs work together: when one contracts (agonist), the other relaxes (antagonist).

关节处的运动类型包括屈、伸、外展、内收、旋转等。例如，肱二头肌引起肘关节屈曲，肱三头肌引起肘关节伸展。拮抗肌群协同工作：一块收缩（主动肌）时，另一块放松（拮抗肌）。

7. Cardiorespiratory System Responses to Exercise | 心肺系统对运动的反应

During exercise, the body undergoes immediate and short-term changes to meet increased oxygen and energy demands. The heart rate (HR), stroke volume (SV) and cardiac output (Q) all rise.

运动时，身体会出现即时和短期的变化，以满足增加的氧气和能量需求。心率 (HR)、每搏输出量 (SV) 和心输出量 (Q) 都会升高。

Cardiac Output (Q) = Stroke Volume (SV) × Heart Rate (HR)

心输出量 (Q) = 每搏输出量 (SV) × 心率 (HR)

Breathing rate and tidal volume increase to take in more oxygen and expel carbon dioxide. Over time, regular training leads to long-term adaptations: a lower resting heart rate, increased stroke volume, stronger respiratory muscles and improved efficiency.

呼吸频率和潮气量增加以摄取更多氧气并排出二氧化碳。长期规律训练会带来长期适应：静息心率降低、每搏输出量增加、呼吸肌增强、系统效率提高。

8. Nutrition for Sports Performance | 运动营养

Proper nutrition fuels performance and aids recovery. A balanced diet should provide carbohydrates, proteins, fats, vitamins, minerals, fibre and water.

合理的营养为运动表现提供燃料并帮助恢复。均衡膳食应提供碳水化合物、蛋白质、脂肪、维生素、矿物质、膳食纤维和水。

Carbohydrates: the main energy source, stored as glycogen in muscles. 碳水化合物：主要能量来源，以糖原形式储存于肌肉。
Proteins: essential for muscle repair and growth. 蛋白质：对肌肉修复和生长至关重要。
Fats: provide sustained energy for low-intensity, long-duration activity. 脂肪：为低强度长时间活动提供持续能量。
Hydration is critical; even slight dehydration can impair performance and concentration. 水分补充极其重要；轻微脱水就可能影响表现和专注力。

Timing matters: a pre-exercise meal should be rich in complex carbohydrates; post-exercise recovery includes protein and carbohydrates to replenish stores. 时机很重要：运动前餐应富含复合碳水化合物；运动后恢复需要蛋白质和碳水化合物以补充储备。

9. Safety in Physical Activity | 体育活动安全

Safety is fundamental to all practical sport and exercise. A thorough warm-up and cool-down reduce injury risk and improve performance.

安全是所有体育实践和运动的基础。充分的热身和放松可以降低受伤风险并提高表现。

Warm-up: pulse-raising activities, dynamic stretches and sport-specific drills. 热身：提升心率的运动、动态拉伸和专项练习。
Cool-down: gentle aerobic activity and static stretching to aid recovery and prevent stiffness. 放松：温和的有氧活动和静态拉伸，帮助恢复并防止肌肉僵硬。

Appropriate clothing and footwear, safe equipment and environment, adherence to rules and fair play also form the foundation of safe participation. Knowledge of personal limits and correct technique further minimises risk.

合适的服装和鞋类、安全的器材和环境、遵守规则与公平竞赛也是安全参与的基础。了解个人极限和正确技术进一步降低风险。

10. Planning a Personal Exercise Programme (PEP) | 制定个人锻炼计划

A Personal Exercise Programme (PEP) uses the principles of training to meet individual goals. Students learn how to design, monitor and evaluate their own programme.

个人锻炼计划 (PEP) 运用训练原则来达成个人目标。学生学习如何设计、监控和评估自己的计划。

Key steps: identify fitness components to improve, set SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound), apply FITT, choose appropriate training methods, and record progress. Regular reviews allow adjustments based on improvements or plateaus.

关键步骤：明确要提升的体能要素，设定 SMART 目标（具体、可衡量、可实现、相关、有时限），应用 FITT 原则，选择合适的训练方法，并记录进展。定期回顾可以根据进步或平台期进行调整。

A well-designed PEP also considers safety measures, warm-up/cool-down, and nutritional strategies, making it a holistic approach to fitness development.

精心设计的 PEP 还会考虑安全措施、热身/放松以及营养策略，从而形成一种全面的体能发展方法。
