📚 Year 10 CAIE Physical Education: Key Points for Experimental/Practical Assessment | Year 10 CAIE 体育：实验/实践考核要点
For Year 10 students following the CAIE IGCSE Physical Education (0413) syllabus, the practical component is just as vital as the theory paper. It accounts for 50% of the final grade and demands that you not only demonstrate physical competence but also collect data from fitness tests and physiological experiments, and carry out an analysis of performance. This article breaks down the key points you must master for experimental and practical assessments, guiding you through each area with essential revision tips.
对于学习 CAIE IGCSE 体育 (0413) 课程的 Year 10 学生来说，实践部分与理论试卷同等重要。它占总成绩的 50%，除了要求你展现身体能力外，还需要从体能测试和生理实验中采集数据，并完成表现分析。本文梳理了实验与实践考核必须掌握的要点，引导你逐一攻克关键内容并提供备考建议。
1. Understanding the Practical Assessment Structure | 理解实践考核结构
The practical assessment (Component 2) requires you to offer four activities from at least two different categories, such as games, swimming, dance or gymnastics. Each activity is marked out of 20, focusing on execution, decision‑making and tactical awareness. You also need to complete an Analysis of Performance (AoP) task worth 20 marks. In Year 10, you will build the skills to observe, record and evaluate performance using fitness components, movement principles and training methods.
实践考核（Component 2）要求你提供至少两个不同类别（如球类、游泳、舞蹈或体操）的四项活动。每项活动满分 20 分，重点关注技术执行、决策能力和战术意识。此外，你还需要完成一项表现分析 (AoP) 任务，占 20 分。在 Year 10 阶段，你将逐步培养运用体能要素、动作原理和训练方法来观察、记录和评价表现的能力。
2. Fitness Testing: Cardiovascular Endurance | 体能测试：心肺耐力
Cardiovascular endurance tests estimate the body's ability to deliver oxygen to working muscles. The most common protocols are the Multi‑Stage Fitness Test (beep test) and the Cooper 12‑minute run. You need to follow the test instructions precisely, record the final level/shuttle or distance, and use standardised tables to predict VO₂max. Understand that bleep test results are influenced by pacing, motivation and practice.
心肺耐力测试可估算身体向工作肌群输送氧气的能力。最常见的方案是多阶段体能测试（哔声测试）和库珀 12 分钟跑。你需要严格遵循测试流程，记录最终级别/折返次数或距离，并使用标准表格推测最大摄氧量（VO₂max）。要理解哔声测试的成绩会受到节奏控制、积极性和练习效果的影响。
| Test | 测试 | Key Metric | 关键指标 |
|---|---|---|---|
| Multi‑Stage Fitness Test | 多阶段体能测试 | Level and shuttle | 级别与折返次数 |
| Cooper 12‑minute run | 库珀 12 分钟跑 | Distance covered (metres) | 跑进距离（米） |
When writing up the experiment, always state the test purpose, describe the procedure, present raw data in a table, calculate the predicted VO₂max and analyse reliability. For example, the Cooper run can be less reliable on a windy day or with an undulating course, so note any limitations.
在撰写实验报告时，务必说明测试目的、描述步骤、用表格呈现原始数据、计算推测的 VO₂max 并分析可靠性。例如，库珀跑在刮风天气或起伏路线上可靠性会降低，因此要注明局限性。
3. Fitness Testing: Strength, Power and Muscular Endurance | 体能测试：力量、爆发力和肌肉耐力
Different tests target specific fitness components. Use the handgrip dynamometer for static strength, the vertical jump or standing broad jump for explosive power, and the one‑minute sit‑up or press‑up test for muscular endurance. Always calibrate equipment, explain the test to the participant, and complete a standardised warm‑up.
不同的测试针对特定的体能要素。使用握力计测量静态力量，垂直跳或立定跳远测量爆发力，一分钟仰卧起坐或俯卧撑测量肌肉耐力。始终要校准设备、向受试者说明测试流程，并完成标准化的热身活动。
| Fitness Component | 体能要素 | Example Test | 示例测试 |
|---|---|---|---|
| Muscular Strength | 肌肉力量 | Handgrip dynamometer | 握力计 |
| Power | 爆发力 | Vertical jump test | 垂直跳测试 |
| Muscular Endurance | 肌肉耐力 | 60‑second sit‑up test | 60 秒仰卧起坐测试 |
In your practical file, record the exact score, the number of trials (usually best of three) and any factors that might affect performance, such as fatigue from previous tests. Compare results with normative tables and suggest how the participant could improve the fitness component.
在实践中，要记录精确分值、测试次数（通常取三次中的最佳值）以及可能影响表现的因素，如先前测试带来的疲劳。将结果与常模表对照，并针对如何改善该体能要素提出建议。
4. Fitness Testing: Flexibility and Body Composition | 体能测试：柔韧性和身体成分
Flexibility is commonly assessed with the sit‑and‑reach test. Ensure the participant removes shoes, sits with straight legs and pushes the slider slowly. Body composition can be estimated using skinfold callipers (e.g., triceps, suprailiac) or Body Mass Index (BMI). Remember that BMI does not distinguish between muscle and fat mass, so for athletes skinfold measurements are often more valid.
柔韧性通常用坐位体前屈测试评估。确保受试者脱鞋、直腿坐好，缓慢推动游标。身体成分可通过皮褶卡钳（如肱三头肌、髂嵴上缘）或身体质量指数 (BMI) 估算。请记住，BMI 无法区分肌肉和脂肪，因此对于运动员而言，皮褶测量通常更有效。
Calculate BMI with the formula: BMI = weight (kg) ÷ height² (m). For skinfold tests, take measurements on the right side of the body, use the average of three readings and then apply a prediction equation to estimate body fat percentage. Discuss ethical considerations, such as privacy and body image sensitivity.
计算 BMI 的公式：BMI = 体重 (kg) ÷ 身高² (m)。对于皮褶测试，应在身体右侧测量，取三次读数的平均值，然后代入推测方程估算体脂百分比。还要讨论隐私和身体意象敏感性等伦理考量。
5. Skill Performance Assessment | 技能表现评估
In each activity you must demonstrate a range of core and advanced skills under conditioned or competitive situations. For example, in badminton, you might be assessed on serving, overhead clears, net play and tactical positioning. Practice structured drills that isolate individual skills and then progress to full gameplay. Your teacher will mark your control, fluency and decision‑making using the CAIE activity‑specific criteria.
在每个活动中，你需要在条件限制或比赛情境下展示一系列核心和高级技能。例如在羽毛球中，可能会评估发球、高远球、网前技术和战术跑位。练习单技能分解的专项训练，再进阶到完整的比赛情境。教师会根据 CAIE 各项活动的评分标准，对你的控制力、流畅度和决策能力进行打分。
Film yourself performing skills so that you can analyse technique later. In the Analysis of Performance task, you will need to describe strengths, weaknesses and suggest drills for improvement. Keep a logbook detailing the skills you have practised, the feedback received and how you have attempted to correct errors.
给自己拍摄技能表现视频，以便后期分析技术。在表现分析任务中，你需要描述优点和弱点，并给出改进的练习建议。记录练习日志，写明练习过的技能、收到的反馈以及你如何尝试纠错。
6. Physiological Experiment: Heart Rate Monitoring | 生理实验：心率监测
e morning, then record exercise HR manually (radial/carotid pulse for 15 seconds × 4) or with a heart‑ate monitor. Plot the data on a graph showing the rise during work and the recovery curve.
在运动前、运动中和运动后监测心率 (HR)，可帮助你研究心血管的反应。早晨醒后即测量安静心率，随后在运动中手动测量脉搏（桡动脉/颈动脉 15 秒 × 4）或使用心率监测器记录运动心率。将数据绘图，显示运动期间心率的上升曲线和恢复曲线。
Calculate HRmax using: HRmax = 220 − age. For a 15‑year‑old, HRmax is approximately 205 bpm. The target training zone for moderate aerobic work is 60–80% of HRmax. Use the Karvonen formula to incorporate resting HR: Target HR = HRrest + (Intensity × (HRmax − HRrest)). In your write‑up, discuss anticipatory rise, steady‑state HR and how cardiovascular fitness affects recovery rate.
用公式计算最大心率：HRmax = 220 − 年龄。15 岁学生的 HRmax 约为 205 bpm。有氧耐力训练的目标区间为 HRmax 的 60‑80%。用卡沃南公式可纳入安静心率：目标心率 = HRrest + (强度 × (HRmax − HRrest))。在实验报告中，讨论预期性心率升高、稳态心率以及心血管适能如何影响恢复速率。
7. Physiological Experiment: Respiratory Measurements | 生理实验：呼吸测量
Spirometry and peak flow meters are used to measure lung volumes and airflow. Tidal volume and vital capacity can be estimated with a spirometer. Peak expiratory flow rate (PEFR) is a quick measure of how fast air can be blown out of the lungs. For Year 10 practical experiments, you are likely to use a peak flow meter and to count breathing rate before and after exercise.
肺活量计和峰流速仪用于测量肺容量和气流。潮气量和肺活量可用肺活量计粗略估计。呼气峰流速 (PEFR) 可以快速衡量呼气速度。在 Year 10 实践实验中，你可能会使用峰流速仪，并在运动前后计数呼吸频率。
Record breathing rate by counting chest rises for 30 seconds and multiplying by 2. After exercise, the rate should increase to meet oxygen demand. Compare values at rest, immediately after a step‑test, and after two minutes of recovery. Present the results in a table and graph, and discuss how tidal volume and breathing rate combine to increase minute ventilation.
通过计数 30 秒胸廓起伏次数再乘以 2 来记录呼吸频率。运动后，呼吸频率会升高以满足氧需。对比安静时、阶跃测试后即刻以及恢复 2 分钟后的数值。用表格和图表呈现结果，并讨论潮气量和呼吸频率如何共同提高每分通气量。
8. Analysis of Movement: Planes and Axes | 动作分析：平面与轴
Movement can be described in three planes: sagittal (forward/backward), frontal (side‑to‑side) and transverse (rotation). Each plane is paired with a corresponding axis. A forward somersault occurs in the sagittal plane about the transverse axis, while a cartwheel occurs in the frontal plane about the sagittal axis. Identifying the correct plane and axis is essential for the AoP task.
动作可在三个平面中描述：矢状面（前后）、额状面（左右）和水平面（旋转）。每个平面都与相应的轴配对。前空翻发生在矢状面绕横轴旋转，而侧手翻发生在额状面绕矢状轴旋转。正确识别平面与轴对表现分析任务至关重要。
When analysing a sporting action, describe the joint movement (e.g., flexion at the hip) and then assign the plane and axis. For instance, a bicep curl at the elbow is flexion/extension in the sagittal plane about the transverse axis. Practice this vocabulary using video clips of your own performances.
在分析运动动作时，先描述关节运动（如髋关节屈曲），再确定平面和轴。例如，哑铃弯举时的肘关节屈/伸发生在矢状面绕横轴。用你自己的动作视频练习这些术语。
9. Analysis of Movement: Levers in the Body | 动作分析：身体中的杠杆
The human body operates as a system of levers, where bones are the levers, joints are the fulcra, muscles provide effort and body weight or external objects are the load. A first‑class lever (e.g., neck extending) has the fulcrum between effort and load. A second‑class lever (e.g., standing on tiptoe) has the load between fulcrum and effort; it offers mechanical advantage. Most movements are third‑class levers (e.g., bicep curl) where the effort lies between fulcrum and load, favouring speed and range over strength.
人体可以看作一个杠杆系统，骨骼是杠杆，关节是支点，肌肉提供动力，体重或外界物体则是阻力。第一类杠杆（如伸颈动作）的支点位于动力与阻力之间。第二类杠杆（如提踵站立）的阻力位于支点和动力之间，可获得省力效果。大多数动作属于第三类杠杆（如哑铃弯举），动力位于支点和阻力之间，牺牲力量以换取速度和运动幅度。
In your analysis, draw simple stick‑figure diagrams, label the effort, fulcrum and load, and state the lever class. Relate the lever type to the movement outcome – for example, third‑class levers enable rapid kicks in football, whereas a second‑class lever in the ankle aids powerful push‑off in sprinting.
在分析时，画出简化的线条图，标注动力、支点和阻力，并说明杠杆类别。将杠杆类型与动作效果联系起来——例如，第三类杠杆使足球射门时快速摆腿成为可能，而脚踝处的第二类杠杆则有助于短跑时的有力蹬伸。
10. Observation of Performance and Feedback | 表现观察与反馈
Effective observation forms the backbone of the Analysis of Performance task. You must be able to identify strengths and areas for improvement using a structured approach. Create an observation checklist that breaks the skill into preparation, execution and recovery phases. Watch a peer or video, and mark each phase.
有效的观察是表现分析任务的基石。你必须能够运用结构化方法识别优势和改进点。制作一份观察清单，将技能拆分为准备、执行和恢复阶段。观看同伴或视频，标记每个阶段。
After observing, deliver feedback using the ‘’ method: positive comment → instruction for improvement → positive comment. For instance, ' nsfer your weight from back to front foot during the smash. Your wrist snap was excellent.' This makes feedback constructive and motivating.
观察后，使用“三明治”法给予反馈：正面评价 → 改进指导 → 正面评价。例如，“你的球拍握法正确，但在扣杀时需要把重心从后脚转移到前脚。你的手腕鞭打很出色。”这样的反馈既具有建设性又鼓舞人心。
11. Safety and Ethical Considerations in Practical Work | 实践中的安全与伦理考量
All practical activities must follow strict safety protocols. Always begin with a dynamic warm‑up and end with a cool‑down to reduce injury risk. When conducting fitness tests, obtain informed consent from participants, explain the right to withdraw, and keep data confidential. Check equipment like treadmills, bikes and weights for wear and tear before use.
所有实践活动都必须遵循严格的安全规范。始终以动态热身开始、以整理活动结束，以降低损伤风险。进行体能测试时，要获得受试者的知情同意，说明可随时退出的权利，并对数据保密。使用跑步机、自行车、力量器械前，检查其磨损情况
