1. Exam Overview and Mark Allocation | 考试概览与评分分配
The CCEA IGCSE Physical Education unit test is usually divided into Section A with short-response and multiple-choice questions, and Section B with data-response and extended-writing questions. The total mark is often 80, with roughly 60% covering applied physiology, health and fitness, and 40% covering skill acquisition and socio-cultural influences.
CCEA IGCSE 体育单元测试通常分为 A 卷（简答与选择题）和 B 卷（数据分析和扩展写作），总分一般为 80 分。其中约 60% 考查应用生理学、健康与体适能，40% 考查技能习得与社会文化影响。
Mark schemes reward accurate use of technical terms such as ‘aerobic capacity’, ‘progressive overload’ and ‘specificity’. Do not write vague phrases like ‘get fitter’ without linking them to a fitness component or training method. Always read the command word, because ‘state’ requires a short answer while ‘evaluate’ requires a judgement supported by reasons.
评分标准奖励准确使用“有氧能力”“渐进超负荷”“专项性”等技术术语。不要只写“变得更强壮”这类模糊表达，而要与体适能成分或训练方法联系起来。务必阅读指令词，因为“陈述”只需简短回答，而“评估”则需要给出有理由支持的判断。
2. Components of Fitness and Testing | 体适能组成与测试
A typical mock question asks: ‘Identify the health-related component of fitness measured by the multi-stage fitness test.’ The answer is cardiovascular endurance, also called aerobic capacity. The test involves running shuttles between two points in time with increasing speed.
一道典型的模拟题会问：“多阶段体能测试测量的是哪种健康相关体适能成分？”答案是心血管耐力，也称为有氧能力。该测试要求在两标志点之间进行折返跑，速度逐渐加快。
Another question may ask about the sit and reach test. This measures flexibility, specifically of the hamstrings and lower back. A valid test requires a standardised warm-up and a ruler or sit-and-reach box with the feet flat against the box. Record the best of three attempts in centimetres.
另一题可能考查坐位体前屈测试。它测量柔韧性，尤其是腘绳肌和下背部的柔韧性。有效测试要求标准化热身，并使用带刻度的坐位体前屈箱，双脚平贴箱面。记录三次尝试中的最佳成绩，单位为厘米。
Skill-related components include agility, balance, coordination, power, reaction time and speed. For example, the Illinois agility test measures agility, while the 30 m sprint test measures speed. In a table question, do not confuse power with strength: power is the ability to exert force quickly, such as in a shot put.
技能相关体适能包括敏捷性、平衡、协调、爆发力、反应时和速度。例如，伊利诺伊敏捷性测试测量敏捷性，30 米冲刺测试测量速度。在表格题中，不要把爆发力与力量混淆：爆发力是快速发力的能力，例如推铅球。
3. Musculoskeletal System Basics | 运动系统基础
Questions often require labelling a diagram of a synovial joint, such as the knee or elbow. Key structures are cartilage, synovial membrane, synovial fluid, ligament and tendon. Cartilage reduces friction and acts as a shock absorber, while synovial fluid lubricates the joint.
考题常要求标注滑膜关节示意图，例如膝关节或肘关节。关键结构包括软骨、滑膜、滑液、韧带和肌腱。软骨减少摩擦并起缓冲作用，滑液则润滑关节。
When a muscle contracts, it pulls on a bone via a tendon. For example, during elbow flexion, the biceps brachii is the agonist, or prime mover, and the triceps brachii is the antagonist. Isometric contraction occurs when there is tension but no change in muscle length, such as holding a plank position.
肌肉收缩时通过肌腱牵拉骨骼。例如，肘关节屈曲时，肱二头肌是主动肌，肱三头肌是对抗肌。等长收缩指产生张力但肌肉长度不变，例如保持平板支撑姿势。
A mock question could be: ‘Explain how antagonistic muscle pairs work at the knee during a football kick.’ The quadriceps group extends the knee as the agonist, while the hamstrings act as the antagonist to control the movement and prevent over-extension.
模拟题可能为：“解释足球踢球时膝关节的拮抗肌对如何工作。”股四头肌群作为主动肌伸展膝关节，腘绳肌作为对抗肌控制动作并防止过度伸展。
4. Energy Systems and Exercise Intensity | 能量系统与运动强度
The body uses three energy systems: ATP-PC, lactic acid, also called anaerobic glycolysis, and aerobic. The ATP-PC system provides immediate energy for high-intensity efforts lasting up to 10 seconds, such as a 100 m sprint or a jump shot. It does not require oxygen and produces no lactic acid.
人体使用三个能量系统：ATP-PC 系统、乳酸系统（也称为无氧糖酵解）和有氧系统。ATP-PC 系统为持续时间不超过 10 秒的高强度运动提供即时能量，例如 100 米冲刺或跳投。它不需要氧气，也不产生乳酸。
The lactic acid system dominates in efforts of 30-90 seconds, such as a 400 m run. It produces lactic acid, which can cause fatigue and muscle soreness. The aerobic system supplies energy for longer, lower-intensity activities by using oxygen to break down carbohydrates and fats.
乳酸系统在 30-90 秒的运动中占主导，如 400 米跑。它产生乳酸，可能导致疲劳和肌肉酸痛。有氧系统利用氧气分解碳水化合物和脂肪，为时间较长、强度较低的活动供能。
In a data-response question, students may be given a graph of heart rate during a 20-minute continuous run. At steady state, heart rate plateaus around 150-170 bpm for a trained adolescent, indicating aerobic work. Above the anaerobic threshold, ventilation and lactate rise sharply, so the pace cannot be maintained for long.
在数据分析题中，可能给出 20 分钟持续跑时的心率曲线。在稳定状态下，训练有素的青少年心率平台大约在 150-170 bpm，表明以有氧供能为主。超过无氧阈后，通气量和乳酸会急剧上升，因此配速无法维持很长时间。
5. Training Principles and Periodisation | 训练原则与周期
The FITT principle stands for Frequency, Intensity, Time and Type. To improve cardiovascular endurance, a student should train 3-5 times per week at 60-80% of maximum heart rate for 20-30 minutes using continuous or interval methods. The maximum heart rate can be estimated as 220 minus age.
FITT 原则指频率、强度、时间和类型。要提高心血管耐力，学生应每周训练 3-5 次，强度为最大心率的 60-80%，每次 20-30 分钟，采用持续训练或间歇训练法。最大心率可用 220 减去年龄来估算。
Progressive overload means gradually increasing the training demand beyond what the body is used to. Without overload, fitness gains plateau. Specificity means training should match the demands of the sport or activity, such as a swimmer training in water rather than only running on land.
渐进超负荷指逐渐将训练负荷增加到超过身体已适应的水平。没有超负荷，体适能提升会停滞。专项性指训练应匹配运动项目的需求，例如游泳运动员应在水中训练，而不是只进行陆上跑步。
A periodised plan divides the season into macrocycle, mesocycle and microcycle. Pre-season focuses on general conditioning, competitive season on maintaining fitness and peaking, and transition on recovery. This helps prevent overtraining and ensures the athlete is at peak fitness for major competitions.
周期化训练计划将赛季分为大周期、中周期和小周期。赛季前重点为一般体能储备，竞赛期重点为保持体能和达到最佳状态，过渡期则以恢复为主。这有助于防止过度训练，并确保运动员在重大比赛时处于最佳体能状态。
6. Skill Acquisition and Feedback | 技能习得与反馈
Skills are classified as open or closed, gross or fine, discrete, serial or continuous. A basketball free throw is a closed, discrete skill because the environment is stable and the action has a clear beginning and end. A 50 m sprint is a gross, closed skill, while a tennis rally is an open skill because the player must react to a changing environment.
技能可分为开放/闭锁、粗大/精细、分立/序列/连续。篮球罚球属于闭锁、分立技能，因为环境稳定且动作有明确的开始和结束。50 米短跑属于粗大、闭锁技能，而网球对打属于开放技能，因为运动员必须对变化的环境作出反应。
Feedback can be intrinsic, from within the performer, or extrinsic, from a coach or video. Knowledge of results tells the performer the outcome, such as ‘the ball landed 2 metres from the target’. Knowledge of performance gives information about technique, such as ‘your elbow dropped during release’.
反馈可以是内在的（来自练习者自身）或外在的（来自教练或录像）。结果反馈告知练习者结果，如“球落在距目标 2 米处”。表现反馈提供技术信息，如“球出手时你的肘部下垂了”。
A common mock question asks students to explain guidance types: visual by demonstration, verbal by instruction, manual by physical support, and mechanical by using equipment such as buoyancy aids in swimming. For a beginner, visual and manual guidance are often most effective because they help build a correct movement pattern.
模拟题常要求解释指导类型：视觉指导通过示范，语言指导通过讲解，手法指导通过身体扶持，器械指导通过使用设备如游泳中的浮力辅助工具。对初学者来说，视觉和手法指导通常最有效，因为它们有助于建立正确的动作模式。
7. Nutrition, Hydration and Performance | 营养、水分与运动表现
A balanced diet for an adolescent athlete should include about 55-60% carbohydrate, 15-20% protein and 25-30% fat. Carbohydrate is the main fuel for high-intensity exercise, while protein supports muscle repair and growth. Fat is used for low-intensity, long-duration activity and insulation.
青少年运动员的均衡膳食应包含约 55-60% 的碳水化合物、15-20% 的蛋白质和 25-30% 的脂肪。碳水化合物是高强度运动的主要燃料，蛋白质则支持肌肉修复和生长。脂肪用于低强度、长时间活动以及保温。
Hydration is critical because a fluid loss of only 2% of body mass can reduce aerobic performance and cognitive function. Athletes should drink small amounts regularly before, during and after exercise, rather than waiting until they feel thirsty. Water is sufficient for sessions under 60 minutes.
水分补充至关重要，因为仅失去体重 2% 的水分就可能导致有氧表现和认知功能下降。运动员应在运动前、中、后少量多次补水，而不是等到口渴才喝。60 分钟以内的运动喝水就足够了。
A data-response question may provide a table of two athletes’ diets and ask which one is more suitable for a marathon runner. Look for high carbohydrate intake, adequate fluid and a pre-event meal 3-4 hours before competition. Avoid high-fat, high-protein meals immediately before racing because they slow gastric emptying.
数据分析题可能给出两名运动员的饮食表，要求判断哪一份更适合马拉松选手。答题时应关注高碳水化合物摄入、充足水分以及赛前 3-4 小时的赛前餐。临赛前避免高脂肪、高蛋白饮食，因为它们会减慢胃排空。
8. Injury Prevention and First Aid | 伤病预防与急救
Injury prevention includes a thorough warm-up, cool-down, appropriate footwear, progressive overload and correct technique. A warm-up should include pulse-raising activities, dynamic stretching and sport-specific drills. The cool-down should include light jogging and static stretching to remove waste products.
伤病预防包括充分热身、整理放松、合适的鞋具、渐进超负荷和正确技术。热身应包括提升心率的运动、动态拉伸和专项练习。整理放松应包括慢跑和静态拉伸，以清除代谢废物。
Common acute injuries are sprains, which are ligament damage, strains, which are muscle or tendon damage, and fractures. RICER is the first aid protocol: Rest, Ice, Compression, Elevation, Referral. Ice should be applied for 20 minutes every 2 hours, but never directly onto skin, as this can cause ice burns.
常见急性损伤包括扭伤（韧带损伤）、拉伤（肌肉或肌腱损伤）和骨折。RICER 是急救处理原则：休息、冰敷、加压、抬高、转诊。冰敷应每次 20 分钟、每 2 小时一次，但不可直接接触皮肤，以免造成冻伤。
In a mock scenario, a hockey player twists her ankle and cannot bear weight. The correct response is to stop play, apply RICER, and refer to a medical professional. Do not massage or apply heat in the first 48 hours because this can increase swelling and bleeding.
在模拟情景中，一名曲棍球运动员扭伤脚踝且无法承重。正确的处理是停止运动、实施 RICER 并转诊给医疗专业人员。最初 48 小时内不要按摩或热敷，因为这会加重肿胀和出血。
9. Socio-Cultural Influences and Ethics | 社会文化影响与伦理
Participation in physical activity is influenced by age, gender, disability, socioeconomic status, culture and access to facilities. CCEA questions may ask students to explain how a local council could increase participation among teenage girls. A good answer names specific barriers and offers practical solutions.
体育活动的参与受年龄、性别、残障、社会经济地位、文化和设施可达性等因素影响。CCEA 的题目可能要求学生解释地方议会如何提高少女的参与率。好的答案会指出具体障碍并提供可行的解决方案。
Strategies include providing female-only sessions, affordable pricing, safe transport, positive role models and a wider range of activities such as dance, martial arts and netball. Removing barriers is more effective than simply telling people to exercise, because many groups face practical and cultural constraints.
策略包括设立女性专属时段、合理收费、安全交通、积极的榜样以及提供舞蹈、武术和无板篮球等更丰富的活动。消除障碍比单纯要求人们锻炼更有效，因为许多群体面临实际和文化上的限制。
Ethics in sport covers sportsmanship, gamesmanship and deviance. Sportsmanship means respecting rules and opponents, while gamesmanship involves bending rules without breaking them, such as time-wasting. Deviance includes doping and deliberate foul play. A question may ask you to evaluate the impact of deviance on the integrity of sport.
体育伦理涵盖体育精神、投机取巧和违规行为。体育精神指尊重规则和对手，而投机取巧指不违反规则但钻规则空子，例如拖延时间。违规行为包括使用兴奋剂和故意犯规。题目可能要求你评估违规行为对体育诚信的影响。
