1. Skeletal System & Joint Actions | 骨骼系统与关节动作
Q: Which bone protects the spinal cord?
问：哪块骨骼保护脊髓？
A: The vertebral column (vertebrae).
答：脊柱（椎骨）。
Q: During a press-up, what joint action occurs at the elbow as you push away from the floor?
问：在俯卧撑推离地面时，肘部发生了什么关节动作？
A: Extension.
答：伸。
Q: Identify the type of synovial joint at the hip and explain how its structure allows kicking.
问：说出髋关节所属的滑膜关节类型，并解释其结构如何实现踢球动作。
A: Ball and socket joint. The ball-shaped head of the femur fits into the cup-shaped acetabulum of the pelvis, allowing movement in all directions – flexion, extension, abduction, adduction and rotation – essential for a footballer generating power in a kick.
答：球窝关节。股骨的球状头部嵌入骨盆杯状的髋臼内，允许全方位运动——屈、伸、外展、内收和旋转——这对于足球运动员踢球发力至关重要。
In Eduqas exams, you are expected to link bones and joint actions to sporting movements. Remember that hinge joints (knee, elbow) only permit flexion and extension, while ball-and-socket joints enable the greatest range. When asked for specific bones, be precise: the cranium protects the brain, the ribs and sternum shield the heart and lungs.
在Eduqas考试中你需要将骨骼和关节动作与运动实例联系起来。记住铰链关节（膝、肘）只允许屈伸，而球窝关节活动范围最大。当被问到特定骨骼时要准确：颅骨保护大脑，肋骨和胸骨保护心肺。
2. Muscular System & Movement Analysis | 肌肉系统与动作分析
Q: In a biceps curl, which muscle acts as the antagonist?
问：二头弯举时，哪块肌肉是拮抗肌？
A: The triceps brachii. While the biceps contracts as the agonist to flex the elbow, the triceps relaxes and lengthens to allow the movement.
答：肱三头肌。肱二头肌作为主动肌收缩屈肘时，肱三头肌放松并被拉长以允许动作完成。
Q: What prime mover causes plantar flexion at the ankle when a ballet dancer points her toes?
问：芭蕾舞者绷脚尖时，哪块原动肌产生踝关节的跖屈？
A: The gastrocnemius, assisted by the soleus.
答：腓肠肌，并得到比目鱼肌的辅助。
Q: During a hamstring curl, describe the roles of the hamstrings and quadriceps.
问：在腿弯举中，描述腘绳肌和股四头肌的作用。
A: The hamstrings (agonist) contract to flex the knee, while the quadriceps (antagonist) relax. Reciprocal inhibition ensures smooth motion and prevents injury.
答：腘绳肌（主动肌）收缩使膝屈，股四头肌（拮抗肌）放松。交互抑制确保动作流畅并防止损伤。
Exam tip: always name the muscle and state its role – agonist, antagonist, synergist or fixator. Be ready to analyse movements at the shoulder, elbow, hip and knee using these terms.
应试技巧：始终点明肌肉名称及其角色——主动肌、拮抗肌、协同肌或固定肌。做好用这些术语分析肩、肘、髋、膝运动的准备。
3. Cardiovascular System & Exercise | 心血管系统与运动
Q: A cyclist has a heart rate of 150 bpm and a stroke volume of 80 ml. Calculate cardiac output and show your working.
问：一名自行车运动员心率为150次/分，每搏输出量为80毫升。计算心输出量，写出计算过程。
Cardiac output = heart rate × stroke volume = 150 bpm × 80 ml = 12 000 ml/min = 12 L/min.
答：心输出量 = 心率 × 每搏输出量 = 150 次/分 × 80 毫升 = 12 000 毫升/分 = 12 升/分。
Q: Explain why heart rate increases during a 1500m race.
问：解释1500米赛跑中心率为何上升。
A: The working muscles demand more oxygen and must remove carbon dioxide faster. The sympathetic nervous system releases adrenaline, stimulating the sinoatrial node to increase heart rate. This boosts cardiac output and speeds up oxygen delivery.
答：工作肌肉需要更多的氧气，并必须更快清除二氧化碳。交感神经系统释放肾上腺素，刺激窦房结加快心率。这提高了心输出量，加速氧气输送到肌肉。
Q: What is vascular shunt and how does it benefit a sprinter?
问：什么是血管分流，它对短跑运动员有何益处？
A: Vascular shunt is the redistribution of blood flow away from inactive areas (e.g. digestive organs) towards active skeletal muscles. For a sprinter, this ensures that oxygen and glucose reach the leg muscles rapidly, maximising performance.
答：血管分流是指血液从非活跃区（如消化器官）重新分配到活跃骨骼肌的过程。对短跑运动员而言，这确保氧气和葡萄糖快速抵达腿部肌肉，最大化运动表现。
4. Respiratory System & Gaseous Exchange | 呼吸系统与气体交换
Q: Name the two muscles that contract during quiet inspiration.
问：说出安静吸气时收缩的两块肌肉。
A: The diaphragm and external intercostal muscles.
答：膈肌和肋间外肌。
Q: Define tidal volume and explain what happens to it during intensive exercise.
问：定义潮气量，并说明高强度运动中潮气量如何变化。
A: Tidal volume is the volume of air breathed in or out per breath. During exercise it increases significantly to bring more oxygen into the lungs and expel more carbon dioxide.
答：潮气量是指每次呼吸吸入或呼出的空气量。运动时潮气量显著增加，以便吸入更多氧气、呼出更多二氧化碳。
Q: Describe the pathway of an oxygen molecule from the atmosphere to a working muscle cell.
问：描述一个氧分子从大气进入工作肌肉细胞的路径。
n the alveoli: oxygen diffuses into the blood, binds to haemoglobin in red blood cells, and is transported via the circulatory system to the muscle, where it diffuses into the cells for aerobic respiration.
答：氧气经鼻/口吸入→气管→支气管→细支气管→肺泡。气体交换发生在肺泡：氧气弥散入血液，与红细胞中的血红蛋白结合，通过循环系统运输到肌肉，再弥散进入细胞进行有氧呼吸。
5. Aerobic & Anaerobic Exercise | 有氧与无氧运动
glucose + oxygen → carbon dioxide + water + energy (ATP)
葡萄糖 + 氧气 → 二氧化碳 + 水 + 能量 (ATP)
glucose → energy + lactic acid
葡萄糖 → 能量 + 乳酸
Q: A 400m hurdler relies mainly on which energy system, and why?
问：400米跨栏运动员主要依赖哪种能量系统，为什么？
A: The anaerobic lactic acid system. The event lasts about 45-60 seconds of high-intensity effort, exceeding the capacity of the ATP-CP system but too short for full aerobic dominance. This leads to lactic acid accumulation.
答：无氧乳酸系统。该项目的剧烈运动持续约45-60秒，超出ATP-CP系统的供能极限，但又太短不足以让有氧系统主导，因此导致乳酸堆积。
| Feature / 特征 | Aerobic / 有氧 | Anaerobic / 无氧 |
|---|---|---|
| Oxygen required / 是否需要氧气 | Yes / 是 | No / 否 |
| By-products / 副产物 | CO₂, H₂O / 二氧化碳、水 | Lactic acid / 乳酸 |
| Intensity / 强度 | Low-moderate / 低-中 | High / 高 |
| Duration / 持续时间 | Long (>3 min) / 长（>3分钟） | Short (<90 sec) / 短（<90秒） |
6. Components of Fitness & Testing | 体能要素与测试
Q: A netball centre needs to change direction rapidly to outmanoeuvre opponents. Identify and define the component of fitness most relevant.
问：蓝网球中锋需要快速变向以甩开对手。指出并定义最相关的体能要素。
A: Agility – the ability to change the position of the body quickly and with control.
答：敏捷性——迅速且受控地改变身体位置的能力。
Q: Which fitness test is most suitable for a marathon runner, and what does it measure?
问：哪项体能测试最适合马拉松运动员？它测量什么？
A: The multi-stage fitness test (bleep test) measures cardiovascular endurance / aerobic capacity.
答：多阶段体能测试（哔哔测试）测量心血管耐力/有氧能力。
Q: A gymnast needs to hold a handstand without falling. Name the test for this component and state the unit of measurement.
问：体操运动员需要稳稳倒立。说出针对这一要素的测试名称及其测量单位。
A: The stork stand test measures balance; it is recorded in seconds.
答：鹤立测试测量平衡能力，以秒为单位记录。
Common Eduqas tests also include: handgrip dynamometer for strength (kg), sit-and-reach for flexibility (cm), 30m sprint for speed (s), and the vertical jump for power (cm). Always justify why a specific test is chosen for a given sport.
Eduqas常见测试还包括：握力计测力量（千克）、坐位体前屈测柔韧性（厘米）、30米冲刺测速度（秒）、纵跳测爆发力（厘米）。始终要说明为何选择某个特定测试。
7. Principles of Training & Methods | 训练原则与方法
Q: Explain the principle of overload and give a practical example using the FITT formula.
问：解释超负荷原则，并用FITT公式给出一个实践例子。
A: Overload means working the body harder than normal to bring about physiological adaptations. Using FITT: Frequency (increase from 3 to 4 sessions/week), Intensity (raise from 60% to 70% max heart rate), Time (extend from 20 to 30 minutes), Type (change from jogging to interval running).
答：超负荷是指让身体的负荷超出正常水平以引发生理适应。以FITT为例：频率（从每周3次增加到4次），强度（从最大心率的60%提高到70%），时间（从20分钟延长到30分钟），类型（从慢跑变为间歇跑）。
Q: Which training method is best for developing explosive power for a basketball jump shot?
问：哪种训练方法最适合发展篮球跳投所需的爆发力？
A: Plyometric training (e.g. box jumps, depth jumps) develops power by rapidly stretching and contracting muscles.
答：增强式
