📚 IGCSE CAIE PE: Case Study Practical Drill | IGCSE CAIE 体育：案例分析实战演练

In CAIE IGCSE Physical Education, case study questions test more than recall: they ask you to apply anatomy, physiology, psychology and socio-cultural knowledge to realistic sporting situations. This article provides a structured practical drill with worked examples, examiner-style prompts and self-check tools to help you move from describing concepts to evaluating real athlete scenarios.

在 CAIE IGCSE 体育中，案例分析题考查的不仅是记忆：它要求你将解剖学、生理学、心理学和社会文化知识应用到真实的运动情境中。本文提供结构化的实战演练，包含范例、考官风格题目和自检工具，帮助你从描述概念提升到评价真实运动员场景。

1. Why Case Studies Matter in CAIE PE | 为什么案例分析在 CAIE 体育中重要

Case study questions in CAIE IGCSE Physical Education are designed to assess how well you can transfer textbook knowledge to real-world sporting examples. Instead of asking you to define ‘aerobic endurance’, the examiner may describe a 1500 m runner and ask why her performance drops in the final lap. This requires you to select relevant physiology, training or psychology concepts and explain them in context.

CAIE IGCSE 体育的案例分析题旨在考查你将课本知识迁移到真实运动场景的能力。考官不会直接要求你定义 ‘有氧耐力’，而是可能描述一名 1500 米跑运动员，并问为什么她在最后一圈表现下降。这需要你选择相关的生理学、训练学或心理学概念，并在具体情境中加以解释。

The mark scheme rewards three key skills: knowledge (AO1), application (AO2) and evaluation (AO3). A strong answer does not just list facts; it connects each fact to the athlete, the sport and the scenario. For example, stating ‘fast-twitch fibres contract quickly’ is knowledge, but explaining that a 100 m sprinter relies on Type IIx fibres to generate explosive force is application.

评分方案奖励三项关键技能：知识（AO1）、应用（AO2）和评价（AO3）。高分答案不只是罗列事实；它将每个事实与运动员、运动项目和情境联系起来。例如，说出 ‘快肌纤维收缩快’ 是知识，但解释 100 米短跑运动员依赖 IIx 型肌纤维产生爆发力则是应用。

This practical drill takes you through common case study themes, showing how to build answers that meet the assessment objectives. Use the model paragraphs and self-check tools to test your ability before the exam.

本实战演练将带你梳理常见案例分析主题，展示如何构建满足评估目标的答案。考前使用范例段落和自检工具检验自己的能力。

2. Anatomy and Physiology: The 100 m Sprinter | 解剖与生理：100 米短跑运动员

Case prompt: A 100 m sprinter says her legs ‘burn’ during the last 20 metres and she slows down. Explain the energy system used and why fatigue occurs. (8 marks)

案例题干：一名 100 米短跑运动员说她在最后 20 米时双腿 ‘灼烧’ 并减速。解释她使用的能量系统以及疲劳发生的原因。（8 分）

The dominant energy system in a 100 m sprint is the ATP-PC system, which provides immediate energy without oxygen. Because the event lasts around 10-15 seconds, the athlete initially resynthesizes ATP from phosphocreatine stores. However, PC stores de
