1. Question 1: Health vs Fitness | 问题1：健康与体能的区别
The first question on the mock paper asks: "Define health and explain one difference between health and fitness." (2 marks). To secure both marks, you must provide a clear definition and a distinct contrast.
模拟卷第一题问到："定义健康，并解释健康与体能的一个区别。"（2分）。要拿到满分，你需要给出一个清晰的定义，并指出两者之间一个明确的差异。
Health is defined as a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity. Fitness, on the other hand, is the ability to meet the demands of the environment and carry out daily tasks without undue fatigue. A key difference is that health encompasses all-round well-being, whereas fitness refers specifically to the body's capacity to perform physical activity. For example, a person can be physically fit (able to run a marathon) but may be in poor mental health due to stress; conversely, a person in good emotional health might have low cardiovascular fitness.
健康的定义是身体、心理和社交完全安好的状态，而不仅仅是没有疾病或虚弱。而体能则是指满足环境需求、在不感到过度疲劳的情况下完成日常任务的能力。一个关键区别在于，健康涵盖的是全面的福祉，而体能特指身体进行体育活动的能力。比如，一个人可能体能很好（能跑马拉松），但因压力而心理健康欠佳；反之，一个情绪健康的人可能心血管体能偏低。
2. Question 2: Components of Fitness | 问题2：体能构成要素
Question 2 presents a multiple-choice task: "Which of the following is a health-related component of fitness? A) Agility B) Reaction time C) Muscular endurance D) Balance." The correct answer is C.
问题2是一道选择题："以下哪一项是健康相关体能要素？A) 灵敏性 B) 反应时 C) 肌肉耐力 D) 平衡。" 正确答案是C。
Health-related components are linked to overall physiological health and include cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Skill-related components such as agility, balance, coordination, power, reaction time and speed are more connected to sports performance. Muscular endurance, the ability of a muscle or muscle group to sustain repeated contractions over time, directly impacts daily function and health.
健康相关要素与整体生理健康挂钩，包括心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。而灵敏、平衡、协调、爆发力、反应时和速度等技能相关要素更多与运动表现关联。肌肉耐力，即肌肉或肌群持续进行重复收缩的能力，直接影响日常功能和健康。
3. Question 3: Principles of Training | 问题3：训练原则
Here, you were given a scenario: "A football player wants to improve her sprint speed before the season. State the principle of training she should apply and explain how the FITT principle can be used." (4 marks). This targets specificity and the FITT variables.
此题给出一个场景："一位足球运动员希望在赛季前提高短跑速度。说明她应运用的训练原则，并解释如何运用 FITT 原则。"（4分）。本题考察专项性原则和 FITT 变量。
The principle is specificity – training must be relevant to the demands of the sport. For sprint speed, she needs exercises that replicate the movement pattern and energy system of sprinting. FITT stands for Frequency, Intensity, Time, and Type. Frequency: train 3–4 times per week. Intensity: work at high effort (80–90% of maximum heart rate). Time: all-out efforts lasting 5–15 seconds with full recovery. Type: short sprints, resisted runs, plyometrics. Applying FITT ensures progressive overload without burnout.
该原则是专项性——训练必须与运动项目的要求相关。针对短跑速度，她需要能够复制短跑动作模式和能量系统的练习。FITT 指的是频率、强度、时间和类型。频率：每周训练3–4次。强度：以高强度（最大心率的80–90%）进行。时间：全力冲刺5–15秒并充分恢复。类型：短距离冲刺、抗阻跑、爆发力训练。运用 FITT 可确保渐进超负荷且避免过度训练。
4. Question 4: The Skeletal System | 问题4：骨骼系统
Question 4 asks: "Identify three functions of the skeleton and for each function, name one bone or structure that supports it." (6 marks). This tests knowledge of shape, protection, movement, support, mineral storage and blood cell production.
问题4问到："指出骨骼的三种功能，并分别为每项功能写出一个起支撑作用的骨骼或结构。"（6分）。此题考查形状、保护、运动、支撑、矿物质储存和造血等功能。
| Function | Example bone / structure |
|---|---|
| Protection | Cranium protects the brain |
| Movement | Femur and pelvis form a ball-and-socket joint |
| Structural support | Vertebral column holds the body upright |
| Mineral storage | Long bones store calcium and phosphorus |
| Blood cell production | Bone marrow in flat bones such as the sternum |
For three marks, any valid combination is acceptable. E.g., protection – ribs shield the heart and lungs; support – femur bears body weight; movement – humerus acts as a lever. The key is linking the function directly to a named bone or joint feature.
任一有效组合均可得分。例如：保护——肋骨保护心肺；支撑——股骨支撑体重；运动——肱骨作为杠杆。得分的关键是将功能与具体命名的骨骼或关节特征直接联系起来。
5. Question 5: Muscles and Movement | 问题5：肌肉与运动
This question states: "When performing a bicep curl, the biceps brachii contracts to flex the elbow. Name the antagonist muscle and describe the role of the fixator at the shoulder." (3 marks).
该题陈述："做二头弯举时，肱二头肌收缩使肘关节屈。写出拮抗肌的名称，并描述肩部固定肌的作用。"（3分）。
The antagonist is the triceps brachii. As the biceps contracts (agonist), the triceps must relax to allow controlled flexion. A fixator muscle stabilises the origin of the agonist to ensure efficient movement. In a bicep curl, the deltoid and surrounding shoulder muscles act as fixators – they hold the shoulder joint steady so the biceps can pull without wasting energy on shoulder movement. Without the fixator, the arm may swing, reducing force transfer.
拮抗肌是肱三头肌。当肱二头肌（主动肌）收缩时，肱三头肌必须放松以允许有控制的屈肘动作。固定肌的作用是稳定主动肌的起点，确保动作高效。在二头弯举中，三角肌和肩部周围肌肉作为固定肌——它们保持肩关节稳定，使肱二头肌能够发力而不浪费能量在肩部移动上。如果没有固定肌，手臂可能会摇晃，降低力量传递。
6. Question 6: The Cardiovascular System | 问题6：心血管系统
A calculation-based question: "A 14-year-old student performs steady cycling. Using the formula max HR = 220 – ge, calculate her maximum heart rate and identify the target zone for aerobic training (60–80% intensity)." (3 marks).
一道计算题："一名14岁学生进行稳定骑行。利用公式最大心率=220–年龄，计算她的最大心率，并确定有氧训练的目标区间（60–80%强度）。"（3分）。
Max HR = 220 – 14 = 206 bpm
. High end: 206 × 0.8 = 164.8 ≈ 165 bpm. So the aerobic training zone is approximately 124– improves cardiovascular endurance by strengthening the heart and increasing stroke volume.
目标区间下限：206 × 0.6 = 123.6 ≈ 124 bpm。上限：206 × 0.8 = 164.8 ≈ 165 bpm。因此有氧训练区间大约在124–165次/分钟。在这个区间训练能通过增强心脏功能、提高每搏输出量来提升心血管耐力。
7. Question 7: The Respiratory System | 问题7：呼吸系统
A short-answer question: "Describe the process of gaseous exchange that occurs at the alveoli. In your answer, refer to oxygen and carbon dioxide concentrations." (4 marks).
简答题："描述在肺泡发生的气体交换过程。回答中需提及氧气和二氧化碳的浓度。"（4分）。
Gaseous exchange takes place in the alveoli, tiny air sacs surrounded by capillaries. Inhaled air has a high concentration of oxygen and a low concentration of carbon dioxide. Blood arriving in the pulmonary capillaries has a low oxygen concentration and high carbon dioxide concentration. This creates diffusion gradients: oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled. The thin alveolar walls (one cell thick) provide a short diffusion distance and a large surface area, making gas exchange rapid and efficient.
气体交换发生在肺泡——这些微小气囊被毛细血管包围。吸入的空气含有高浓度氧气和低浓度二氧化碳。到达肺部毛细血管的血液则氧气浓度低、二氧化碳浓度高。这就形成了扩散梯度：氧气从肺泡进入血液，而二氧化碳从血液进入肺泡并被呼出。肺泡壁极薄（仅一个细胞厚度），提供了短的扩散距离和巨大的表面积，使气体交换快速且高效。
8. Question 8: Nutrition and Hydration | 问题8：营养与补水
This extended question asks: "Explain why a balanced diet is important for a teenage athlete. In your answer, refer to macronutrients and micronutrients, and the effects of dehydration on performance." (6 marks).
这道拓展题问到："解释均衡饮食对青少年运动员为何重要。回答中需提及宏量营养素、微量营养素，以及脱水对运动表现的影响。"（6分）。
A balanced diet supplies energy for growth, repair and activity. Macronutrients: carbohydrates provide the main energy source for moderate-to-high intensity exercise; proteins repair and build muscle tissue after training; fats supply long-duration, low-intensity energy and help absorb fat-soluble vitamins. Micronutrients: calcium and vitamin D support bone health, reducing injury risk; iron aids oxygen transport, preventing fatigue. Dehydration of as little as 2% body weight can impair concentration, increase heart rate, reduce endurance and lead to early onset fatigue. Maintaining fluid balance therefore directly protects skill execution and decision-making.
均衡饮食为生长、修复和活动提供能量。宏量营养素：碳水化合物是中高强度运动的主要能源；蛋白质在训练后修复并构建肌肉组织；脂肪提供长时间低强度运动的能量，并帮助吸收脂溶性维生素。微量营养素：钙和维生素 D 支持骨骼健康，降低受伤风险；铁帮助氧气运输，预防疲劳。脱水程度达到体重的2%即可损害专注力、加快心率、降低耐力并导致过早疲劳。因此，维持体液平衡直接保护了技能执行和决策能力。
9. Question 9: Skill Classification | 问题9：技能分类
You are shown two pictures: a tennis serve (externally paced, open skill) and a gymnast performing a floor routine (self-paced, closed skill). The question: "Classify each skill using the open–closed and gross–fine continua. Justify your choices." (4 marks).
题中给出两幅图片：网球发球（外部节奏、开放技能）和体操运动员进行自由操（自我节奏、封闭技能）。问题："使用开放–封闭和粗大–精细连续体对每种技能进行分类，并说明理由。"（4分）。
The tennis serve is an open skill because the performer must adapt to changing conditions – the opponent's position, wind, and ball toss variability. It is also a gross skill requiring large muscle groups (legs, core, shoulder). The gymnastic floor routine is largely a closed skill; the environment is predictable, the sequence is pre-planned, and the athlete executes movements without direct interference. It involves both gross skills (somersaults, leaps) and fine control (toe point, hand placement), but the dominant classification is gross due to whole-body involvement.
网球发球是开放技能，因为运动员必须根据变化的条件进行调整——对手位置、风向和抛球的变化。同时，它也是粗大技能，需要调动大肌肉群（腿、核心、肩部）。体操自由操主要是封闭技能；环境可预测，动作套路预先编排，运动员在没有直接干扰的情况下完成动作。虽然它同时包含粗大技能（空翻、跳跃）和精细控制（绷脚尖、手位），但由于全身参与，主要分类为粗大技能。
10. Question 10: Warm-up and Cool-down | 问题10：热身与放松
The final question: "Outline the three phases of an effective warm-up and explain the physiological benefits of including a cool-down. Use examples from a team sport such as netball." (5 marks).
最后一道题："概述有效热身的三个阶段，并解释进行整理放松活动的生理益处。请以无挡板篮球等团队运动为例。"（5分）。
A warm-up consists of: Phase 1 – pulse raiser (e.g., light jogging) to gradually increase heart rate and blood flow to muscles. Phase 2 – dynamic stretching and mobility exercises (e.g., lunges with rotation, leg swings) to improve joint range of motion and reduce stiffness. Phase 3 – sport-specific drills (e.g., quick passes, footwork patterns) that psychologically prepare players and rehearse neural pathways. A cool-down involves low-intensity activity (slow jog, walking) and static stretching. Benefits: it prevents blood pooling, slowly lowers heart rate, aids removal of metabolic wastes like lactic acid, reduces muscle soreness, and promotes flexibility. In netball, after a match, players perform a gentle jog followed by stretches targeting calves, quads and shoulders to enhance recovery.
热身包括：第一阶段——脉搏提升活动（如慢跑），逐步提高心率，增加肌肉血流量。第二阶段——动态拉伸与灵活性练习（如弓步转体、摆腿），改善关节活动范围，减少僵硬。第三阶段——专项性练习（如快速传球、步法训练），让球员做好心理准备并预演神经通路。整理放松活动包括低强度运动（慢跑、走步）和静态拉伸。其益处：防止血液淤积，缓慢降低心率，帮助清除乳酸等代谢废物，减轻肌肉酸痛，并促进柔韧性。在无挡板篮球比赛中，赛后球员先慢跑再拉伸小腿、股四头肌和肩部，以加速恢复。
