1. Functions of the Skeleton | 骨骼系统的功能
Question: Identify and explain four main functions of the human skeleton. (4 marks)
题目：指出并解释人体骨骼的四项主要功能。（4分）
The skeleton provides support, acting as a rigid framework that maintains the shape of the body and holds vital organs in place.
骨骼提供支撑，作为刚性框架维持身体形状并将重要器官固定在适当位置。
It offers protection by surrounding delicate organs; for instance, the cranium shields the brain and the ribcage guards the heart and lungs.
它通过包裹脆弱器官提供保护；例如，颅骨保护大脑，胸廓保护心脏和肺。
Bones facilitate movement by serving as levers to which muscles attach. When muscles contract, they pull on bones to produce joint actions.
骨骼通过充当杠杆并附着肌肉来促进运动。肌肉收缩时牵拉骨骼产生关节动作。
Bone marrow carries out blood cell production (haematopoiesis), manufacturing red blood cells, white blood cells and platelets.
骨髓执行血细胞生成（造血功能），制造红细胞、白细胞和血小板。
The skeleton stores minerals such as calcium and phosphorus, which can be released into the bloodstream when needed.
骨骼储存矿物质，如钙和磷，需要时可释放到血液中。
2. Types of Muscle Contraction | 肌肉收缩类型
Question: Define the three types of muscle contraction and give a sporting example for each. (3 marks)
题目：定义三种肌肉收缩类型，并各举一个运动实例。（3分）
Isotonic contraction involves a change in muscle length while tension remains relatively constant. It can be concentric, where the muscle shortens (e.g., the biceps during the upward phase of a bicep curl), or eccentric, where the muscle lengthens under tension (e.g., the biceps as the arm extends downward with control).
等张收缩涉及肌肉长度变化而张力相对恒定。它可以是向心收缩（肌肉缩短，例如二头肌弯举的上举阶段），也可以是离心收缩（肌肉在张力下被拉长，例如手臂有控制地下放时二头肌的伸展）。
Isometric contraction occurs when the muscle generates tension but there is no visible change in muscle length. An example is holding the 'crucifix' position on the rings in gymnastics or maintaining a wall sit.
等长收缩发生时肌肉产生张力，但肌肉长度无明显变化。例如体操吊环中保持十字支撑或维持靠墙静蹲。
Isokinetic contraction takes place when the muscle contracts at a constant speed throughout the full range of motion, usually with the aid of specialised machines. An example is swimming arm strokes against controlled resistance or using an isokinetic dynamometer in rehabilitation.
等速收缩发生在整个关节活动范围内肌肉以恒定速度收缩，通常借助专用器械。例如对抗受控阻力的游泳划臂或在康复中使用等速测力仪。
3. Immediate Effects of Exercise on the Cardiovascular System | 运动对心血管系统的即时影响
Question: Describe the immediate responses of the cardiovascular system to a bout of intense exercise. (5 marks)
题目：描述一次剧烈运动过程中心血管系统的即时反应。（5分）
Heart rate increases rapidly to deliver more oxygen-rich blood to working muscles. This is caused by signals from the sympathetic nervous system and the release of adrenaline.
心率迅速上升，向工作肌肉输送更多富氧血液。这是由交感神经系统的信号和肾上腺素的释放引起的。
Stroke volume, the amount of blood ejected per beat, rises due to stronger ventricular contractions and greater venous return.
每搏输出量（心脏每搏动泵出的血量）因心室收缩更有力和静脉回流血量增加而上升。
Cardiac output, the product of heart rate and stroke volume, increases substantially to meet the elevated demand for oxygen.
心输出量（心率与每搏输出量的乘积）显著增加，以满足对氧气的更高需求。
Blood pressure (systolic) rises as arteries expand to accommodate faster blood flow; diastolic pressure stays relatively stable or increases only slightly.
血压（收缩压）随着动脉扩张以容纳更快的血流而升高；舒张压保持相对稳定或仅轻微上升。
Blood is redistributed through vasodilation of arterioles in active muscles and vasoconstriction in non-essential areas such as the digestive system, a process known as shunting.
通过工作肌肉内小动脉的血管舒张以及消化系统等非必需区域的血管收缩，血液被重新分配，这一过程称为血液分流。
4. Principles of Training – FITT | 训练原则 – FITT
Question: A performer wants to improve aerobic endurance. Explain how the FITT principle can be applied to design their training programme. (4 marks)
题目：一名运动员希望提升有氧耐力。解释如何运用FITT原则来设计其训练计划。（4分）
Frequency refers to how often training takes place. For aerobic improvement, a performer should aim for 3-5 sessions per week to allow adequate recovery while building endurance.
频率指训练进行的次数。为提升有氧能力，训练者应每周安排3至5次训练课，既确保充足的恢复，又能增强耐力。
Intensity describes how hard the exercise is. Aerobic endurance is best developed by working within the target heart rate zone, typically 60-80% of maximum heart rate, monitored through heart rate checks or the talk test.
强度描述运动的费力程度。有氧耐力最好在目标心率区间内进行训练，通常为最大心率的60-80%，可通过心率监测或说话测试来把控。
Time is the duration of each session. To stimulate aerobic adaptations, continuous training sessions should last at least 20-30 minutes, gradually extending to 45-60 minutes as fitness improves.
时间指每次训练的持续时间。为刺激有氧适应，持续训练每次至少应进行20-30分钟，随体能提升逐步延长至45-60分钟。
Type is the mode of exercise chosen. Effective aerobic activities include running, cycling, swimming and rowing. The FITT principle helps ensure progressive overload and avoid plateaus.
类型指选择的运动方式。有效的有氧活动包括跑步、骑行、游泳和划船。FITT原则有助于确保渐进式超负荷并避免平台期。
5. Macronutrients and Their Roles | 宏量营养素及其作用
Question: Name the three macronutrients and explain their main functions for a sportsperson. (3 marks)
题目：说出三种宏量营养素，并解释它们对运动员的主要功能。（3分）
Carbohydrates are the body's primary energy source, especially during high-intensity exercise. They are stored as glycogen in muscles and the liver, and a carbohydrate-rich diet supports training endurance and recovery.
碳水化合物是身体的主要能量来源，特别是在高强度运动中。它们以糖原形式储存在肌肉和肝脏中，富含碳水化合物的饮食有助于训练耐力和恢复。
Proteins are essential for growth, repair and maintenance of body tissues, including muscle. Athletes need sufficient protein to rebuild muscle fibres damaged during training and to support strength gains.
蛋白质对于身体组织（包括肌肉）的生长、修复和维持至关重要。运动员需要充足的蛋白质来重建训练中受损的肌纤维，并支持力量增长。
Fats supply a concentrated energy source and are vital for prolonged, moderate-intensity exercise. They also help transport fat-soluble vitamins, protect organs and provide insulation. Healthy unsaturated fats should be prioritised.
脂肪提供浓缩的能量来源，对长时间中等强度运动至关重要。它们还有助于运输脂溶性维生素、保护器官并提供隔热作用。应优先选择健康的不饱和脂肪。
6. Classification of Skills | 技能分类
Question: A basketball free throw and a 100-metre sprint start are two different skills. Classify each using the continua for 'open/closed' and 'discrete/serial/continuous', giving reasons for your answers. (4 marks)
题目：篮球罚球和100米短跑起跑是两种不同的技能。运用'开放/闭合'和'分立/序列/连续'连续体对每一项进行分类，并说明理由。（4分）
A basketball free throw is a closed skill because it is performed in a stable, predictable environment where the performer has complete control over timing and execution; there are no external opponents interfering.
篮球罚球是一项闭合技能，因为它在稳定、可预测的环境中进行，执行者完全控制时机和完成方式；没有外部对手干扰。
The free throw is also a discrete skill because it has a clear beginning and end, lasting a short duration with a single, focused action.
罚球同时也是一项分立技能，因为它有明确的开始和结束，持续时间短，由单一而专注的动作组成。
A 100-metre sprint start is relatively open as it is influenced by external factors such as the starter's gun, weather conditions, and the reaction of other competitors, requiring the athlete to adapt.
100米短跑起跑相对开放，因为它受外部因素影响，如发令枪声、天气状况和其他选手的反应，要求运动员加以适应。
However, the sprint start is primarily a discrete skill because the explosive drive from the blocks is a brief, single movement. The overall sprint could be considered serial, but the start itself is discrete.
然而，短跑起跑主要是一项分立技能，因为从起跑器上的爆发式蹬出是一个短暂、单一的动作。总体短跑可视为序列技能，但起跑本身是分立的。
7. Arousal and the Inverted U Theory | 唤醒与倒U理论
Question: Using the Inverted U Theory, explain how a footballer's performance might be affected by under-arousal, optimum arousal, and over-arousal before a cup final. (3 marks)
题目：运用倒U理论，解释足球运动员在杯赛决赛前，唤醒不足、最佳唤醒和过度唤醒会如何影响其表现。（3分）
Under-arousal occurs when the player feels flat or disinterested. Reaction times slow and the player may lack focus, leading to poor decision-making and sluggish movement on the pitch.
唤醒不足发生时球员感到低迷或漠不关心。反应时间变慢，球员可能注意力涣散，导致决策欠佳和在场上行动迟缓。
At the point of optimum arousal, the footballer is alert, motivated, and fully focused on the task. Performance peaks as concentration and physical readiness are ideally balanced.
在最佳唤醒点，足球运动员机敏、积极并全神贯注于任务。随着注意力和身体准备达到理想平衡，表现达到顶峰。
Over-arousal leads to anxiety, tunnel vision and a decline in performance. The player may rush decisions, experience tight muscles and lose the ability to read the game effectively.
过度唤醒导致焦虑、视野狭窄和表现下降。球员可能会仓促决策、肌肉紧张，并丧失有效解读比赛的能力。
8. Components of Health-Related Fitness | 健康相关体适能成分
Question: List four components of health-related fitness and suggest a suitable fitness test for each. (4 marks)
题目：列出健康相关体适能的四种成分，并为每一种建议一个合适的体适能测试。（4分）
