This walkthrough breaks down a WJEC IGCSE Physical Education unit test into the most commonly examined areas. For each section, you will find a typical question format, key marking points, and advice on how to turn a good answer into a full-mark answer. The aim is to help you understand exactly what the examiner is looking for when command words such as 'describe', 'explain', 'evaluate' or 'justify' appear.

本解析将 WJEC IGCSE 体育单元测试拆分为最高频的考查领域。每个小节都包含典型题型、关键得分点，以及如何把普通答案提升为满分答案的建议。目的是帮助你准确理解当试卷中出现 'describe'、'explain'、'evaluate' 或 'justify' 等指令词时，考官真正想要看到什么。

1. Exam Structure and Command Words | 试卷结构与指令词

A typical WJEC IGCSE Physical Education unit test mixes short-response questions, data interpretation, and one or two extended-writing questions. Marks are allocated for knowledge, application, and evaluation. Reading the command word carefully is the first step to avoiding lost marks: 'state' requires a brief fact, 'describe' needs a developed account, and 'explain' must link cause and effect.

典型的 WJEC IGCSE 体育单元测试混合了简答题、数据解释题，以及一至两道扩展写作题。分值按照知识、应用和评价三个层级分配。仔细阅读指令词是避免丢分的第一步：'state' 要求简洁的事实，'describe' 需要展开说明，而 'explain' 必须建立因果关系。

Question style: 'Explain how the FITT principle can be used to improve cardiovascular endurance.'

题型示例： '解释如何运用 FITT 原则提高心血管耐力。'

A full-mark answer must name frequency, intensity, time and type, then apply each element to aerobic training. For example, training three to five times per week at 60-80% of maximum heart rate for 20-40 minutes using running or cycling will increase stroke volume and capillary density.

满分答案必须说出频率、强度、时间和类型，然后将每个要素应用到有氧训练中。例如，每周训练三至五次，以最大心率的 60-80% 持续 20-40 分钟，采用跑步或骑行，会提高每搏输出量和毛细血管密度。

2. Health-Related Fitness Components | 健康相关体适能要素

WJEC papers frequently ask you to identify the health-related components of fitness: cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. You must be able to link each component to a sporting example and to a health benefit, not just give a definition.

WJEC 试卷经常要求你识别健康相关体适能要素：心血管耐力、肌肉力量、肌肉耐力、柔韧性和身体成分。你必须能够将每个要素与运动实例和健康益处联系起来，而不仅仅是给出定义。

Question: 'A gymnast needs flexibility. Describe one test used to measure flexibility and explain why this component is important for performance.'

题目： '体操运动员需要柔韧性。描述一种测量柔韧性的测试，并解释该要素为何对运动表现重要。'

The sit and reach test is valid: the performer sits with legs extended, reaches forward slowly, and the distance reached is recorded. Flexibility allows a gymnast to achieve a full range of motion in splits and bridge positions, which improves technical quality and reduces the risk of muscle strain.

坐位体前屈测试是有效的：受试者坐姿，双腿伸直，缓慢前伸，记录指尖到达的距离。柔韧性使体操运动员能够在劈叉和桥式动作中达到完整的关节活动范围，从而提高技术质量并降低肌肉拉伤风险。

3. Skill-Related Fitness Components | 技能相关体适能要素

Skill-related components include agility, balance, coordination, power, reaction time, and speed. These are more closely linked to successful movement in sport. In the mock paper, a common task is to match a component to a scenario and justify the choice using a clear link between the component and the action.

技能相关体适能要素包括灵敏性、平衡、协调、爆发力、反应时间和速度。这些要素与体育运动中的成功动作联系更紧密。在模拟卷中，常见任务是将某个要素与情境匹配，并通过要素与动作之间的清晰联系来证明选择合理。

Question: 'Identify the main skill-related fitness component used by a sprinter reacting to the starting gun. Justify your answer.'

题目： '指出短跑运动员对发令枪做出反应时使用的主要技能相关体适能要素。证明你的答案。'

The main component is reaction time, because the time between the stimulus and the start of movement must be minimised. A sprinter with faster reaction time can leave the blocks earlier, which can decide a race where margins are measured in hundredths of a second.

主要要素是反应时间，因为必须尽可能缩短从刺激到动作开始之间的时间。反应时间更短的短跑运动员能够更早地离开起跑器，在百分之一秒决胜负的比赛中，这可能决定最终名次。

4. Principles of Training: SPORT and FITT | 训练原则：SPORT 与 FITT

Examiners expect you to use the SPORT principles of specificity, progression, overload, reversibility, and tedium, together with FITT variables. A high-scoring answer applies these principles to a named athlete and explains how they prevent plateau or injury.

考官希望你能运用 SPORT 原则，即专项性、渐进性、超负荷、可逆性和枯燥性，以及 FITT 变量。高分答案会将这些原则应用到指定运动员身上，并解释它们如何防止平台期或损伤。

Question: 'A football player wants to improve muscular strength. Explain how progressive overload can be applied safely to resistance training.'

题目： '一名足球运动员想提高肌肉力量。解释如何安全地将渐进超负荷应用到抗阻训练中。'

Progressive overload means gradually increasing the resistance, repetitions, or sets as the body adapts. For example, the player might increase the squat load by 2.5-5 kg per week while maintaining correct technique. This encourages further strength gains without overtraining or joint injury.

渐进超负荷指随着身体适应，逐步增加阻力、重复次数或组数。例如，运动员可以在保持正确技术的同时，每周将深蹲负荷增加 2.5-5 公斤。这能促进进一步的力量增长，同时避免过度训练或关节损伤。

5. Training Methods in Practice | 训练方法实践

You need to know the characteristics of continuous training, interval training, fartlek training, circuit training, weight training, and plyometrics. The best answers select one method for a specific athlete, describe a session, and justify why the method matches the demands of the sport.

你需要了解持续训练、间歇训练、法特莱克训练、循环训练、重量训练和增强式训练的特点。最佳答案会为特定运动员选择一种方法，描述一次训练课，并论证该方法为何符合该运动项目的需求。

Question: 'Which training method is most suitable for a 1500 m runner during the pre-season? Describe a session and give two reasons for your choice.'

题目： '哪种训练方法最适合赛季前期的 1500 米跑运动员？描述一次训练课，并给出两个选择的理由。'

Continuous training is suitable because 1500 m is predominantly aerobic. A session could be a 40-minute steady run at 70% of maximum heart rate. It develops aerobic capacity and allows the athlete to build a base safely, which supports later speed work on the track.

持续训练是合适的，因为 1500 米跑以有氧供能为主。一次训练课可以是以最大心率的 70% 进行 40 分钟匀速跑。它能发展有氧能力，让运动员安全地打好基础，为之后在跑道上的速度训练提供支持。

6. Aerobic and Anaerobic Energy Systems | 有氧与无氧能量系统

WJEC questions often ask you to explain how energy is provided during different intensities and durations of exercise. You must be able to distinguish between aerobic respiration using oxygen and anaerobic processes that produce energy quickly but cause lactic acid accumulation.

WJEC 试题经常要求你解释不同强度和持续时间的运动中能量如何供应。你必须能够区分使用氧气的有氧呼吸，以及快速产生能量但会导致乳酸积累的无氧过程。

Question: 'Compare the main energy systems used by a 100 m sprinter and a marathon runner. Explain the consequences for performance and recovery.'

题目： '比较 100 米短跑运动员和马拉松运动员使用的主要能量系统。解释对运动表现和恢复的影响。'

The sprinter relies mainly on the anaerobic ATP-PC and lactic acid systems. Energy is released very quickly without oxygen, but the supply is limited and fatigue occurs rapidly. The marathon runner relies mainly on the aerobic system, which releases energy more slowly but can be sustained for hours. Recovery from anaerobic work takes longer because lactic acid must be removed.

短跑运动员主要依赖无氧的 ATP-PC 和乳酸系统。能量在无氧条件下极快地释放，但供应有限，疲劳迅速发生。马拉松运动员主要依赖有氧系统，该系统释放能量较慢，但可以持续数小时。无氧运动后的恢复时间更长，因为必须清除乳酸。

7. Cardiovascular Responses to Exercise | 运动时心血管系统反应

Short-term responses to exercise include increased heart rate, increased stroke volume, and increased cardiac output. Long-term adaptations include cardiac hypertrophy, lower resting heart rate, increased capillarisation, and faster recovery rate. You should be able to explain each using physiological terms.

运动时的短期反应包括心率升高、每搏输出量增加和心输出量增加。长期适应包括心肌肥厚、安静心率降低、毛细血管密度增加和恢复速度加快。你应该能够使用生理学术语解释每一项变化。

Cardiac output = stroke volume × heart rate

心输出量 = 每搏输出量 × 心率

Question: 'Explain how regular aerobic training lowers resting heart rate and why this is beneficial for an endurance athlete.'

题目： '解释规律的有氧训练如何降低安静心率，以及这对耐力运动员为何有益。'

Regular aerobic training increases stroke volume because the heart muscle becomes larger and stronger. Since cardiac output at rest stays roughly the same, a higher stroke volume allows the heart to pump the required blood with fewer beats per minute. A lower resting heart rate indicates greater cardiac efficiency and allows the athlete to work at a higher intensity before reaching maximum heart rate.

规律的有氧训练通过使心肌变得更大更强来提高每搏输出量。由于安静时的心输出量基本不变，较高的每搏输出量使心脏能够以每分钟更少的搏动次数泵出所需血量。较低的安静心率表明心脏效率更高，使运动员能够在达到最大心率之前以更高强度运动。

8. Respiratory System and Gaseous Exchange | 呼吸系统与气体交换

You need to describe the pathway of air, the mechanics of breathing, and the process of gaseous exchange at the alveoli and muscles. Marks are often lost when students describe oxygen entering the blood but do not mention carbon dioxide moving in the opposite direction.

你需要描述空气的通路、呼吸机制，以及肺泡和肌肉处气体交换的过程。当学生只描述氧气进入血液，而没有提到二氧化碳沿相反方向移动时，往往会丢分。

Question: 'Describe how gaseous exchange takes place at the alveoli. Explain why this process is more efficient in trained athletes.'

题目： '描述肺泡处气体交换的过程。解释为何训练有素的运动员这一过程更高效。'

At the alveoli, oxygen diffuses from a high concentration in the alveolar air into the blood capillaries, where oxygen concentration is lower. Carbon dioxide diffuses from the blood into the alveoli to be exhaled. Trained athletes have greater alveolar surface area and capillary density, so diffusion occurs faster and more oxygen can be delivered to working muscles.

在肺泡处，氧气从肺泡气中的高浓度扩散到氧气浓度较低的毛细血管血液中。二氧化碳从血液扩散进入肺泡被呼出。训练有素的运动员拥有更大的肺泡表面积和毛细血管密度，因此扩散速度更快，更多氧气可以输送到工作肌肉。

9. Musculoskeletal System and Levers | 骨骼肌肉系统与杠杆

Questions on movement analysis often require you to name the agonist and antagonist at a joint, describe the type of contraction, or classify a lever system. Use precise language: the agonist is the muscle that contracts to create movement; the antagonist relaxes or lengthens to allow movement.

运动分析类题目常常要求你指出关节处的主动肌和拮抗肌，描述收缩类型，或划分杠杆系统。使用精确的语言：主动肌是收缩产生动作的肌肉，拮抗肌则放松或拉长以允许动作发生。

Question: 'A basketball player jumps upward to shoot. Identify the main agonist at the ankle during take-off and state the type of contraction occurring in the calf muscles.'

题目： '一名篮球运动员向上跳起投篮。指出起跳时踝关节的主要主动肌，并说明小腿肌肉发生的收缩类型。'

The main agonist at the ankle is the gastrocnemius, assisted by the soleus. During take-off the calf muscles shorten under tension to produce plantar flexion, so this is an isotonic concentric contraction. The antagonist tibialis anterior lengthens at the same time.

踝关节的主要主动肌是腓肠肌，比目鱼肌起辅助作用。起跳时小腿肌肉在张力下缩短产生跖屈，因此这是等张向心收缩。同时拮抗肌胫骨前肌拉长。

10. Nutrition, Hydration and Performance | 营养、水分与运动表现

You should be able to explain the roles of carbohydrates, fats, proteins, vitamins, minerals, fibre, and water in a balanced diet. For performance questions, link carbohydrate loading to endurance events, protein to repair and recovery, and hydration to thermoregulation and prevention of fatigue.

你应该能够解释碳水化合物、脂肪、蛋白质、维生素、矿物质、纤维和水在均衡饮食中的作用。对于运动表现类题目，要将糖原负荷法与耐力项目联系起来，将蛋白质与修复和恢复联系起来，将补水与体温调节和预防疲劳联系起来。

Question: 'Evaluate the use of carbohydrate loading for a marathon runner. Include one advantage and one risk.'

题目： '评价马拉松运动员使用糖原负荷法。包括一个优点和一个风险。'

Carbohydrate loading can increase muscle glycogen stores, which delays fatigue and allows the runner to maintain a high pace for longer. However, if not managed carefully, it may cause water retention, digestive discomfort, or weight gain. The benefit is greatest for events lasting over 90 minutes.

糖原负荷法可以增加肌糖原储备，延缓疲劳，使跑步者能够更长时间保持较高配速。然而，如果管理不当，可能导致水潴留、消化不适或体重增加。对于持续超过 90 分钟的项目，其益处最大。

11. Injury Prevention and Risk Assessment | 损伤预防与风险评估

Injury prevention questions assess your understanding of warm-up, cool-down, protective equipment, rules, and the principle of gradual progression. A strong answer identifies a specific risk in a named activity and explains how a prevention method reduces that risk, rather than simply listing generic advice.

损伤预防类题目考查你对热身、放松、护具、规则和渐进原则的理解。优秀答案会指出某项指定活动中的具体风险，并解释某种预防方法如何降低该风险，而不是简单罗列一般性建议。

Question: 'A rugby player has returned from an ankle sprain. Explain two strategies the coach could use to reduce the risk of re-injury during the first two weeks back.'

题目： '一名橄榄球运动员踝关节扭伤后复出。解释教练在复出后前两周可以采取的两种降低再次受伤风险的策略。'

First, the coach could apply the principle of gradual progression by limiting training load and total contact time, allowing the ankle ligaments to adapt. Second, the player could wear an ankle support or tape during training and matches to provide mechanical stability and limit excessive inversion movement that caused the original sprain.

首先，教练可以运用渐进原则，限制训练负荷和总对抗时间，让踝关节韧带逐步适应。其次，运动员可以在训练和比赛中佩戴踝关节护具或贴布，提供机械稳定性，并限制导致最初扭伤的过度内翻动作。

12. Sample Mark Scheme and Model Answers | 评分标准与参考答案示例

The final part of a walkthrough should show how marking points translate into full-mark answers. WJEC mark schemes often reward three elements: identification of the correct concept, application to the scenario, and a developed explanation. If you include each of these, you protect yourself against losing marks for underdevelopment.

解析的最后一部分应展示得分点如何转化为满分答案。WJEC 评分标准通常奖励三个要素：正确概念的识别、对情境的应用，以及展开的解释。如果你包含这三点，就能避免因答案不够充分而丢分。

Question: 'Analyse the importance of cardiovascular endurance for a hockey midfielder during a 70-minute match.'

题目： '分析心血管耐力对曲棍球中场球员在 70 分钟比赛中的重要性。'

Cardiovascular endurance allows the midfielder to maintain repeated high-intensity runs throughout the match without fatiguing quickly. A high aerobic capacity increases oxygen delivery to working muscles, delays the accumulation of lactic acid, and supports faster recovery between sprints. This helps the player maintain defensive positioning, make attacking runs late in the game, and make better decisions under pressure, especially in the final ten minutes when opponents tire.

心血管耐力使中场球员能够在整场比赛中保持反复的高强度跑动而不迅速疲劳。较高的有氧能力增加向工作肌肉输送的氧气，延缓乳酸积累，并支持冲刺之间的更快恢复。这有助于球员保持防守站位，在比赛后段完成进攻跑动，并在压力下做出更好的决策，尤其是在对手疲劳的最后十分钟。
