📚 KS3 CIE Physical Education: Case Study Practical Exercise | KS3 CIE 体育：案例分析实战演练
Welcome to this case study practical exercise in KS3 CIE Physical Education. In this walkthrough, we will follow a systematic approach to analyse a young athlete's performance, set goals, design a training programme, and evaluate progress. By the end of this exercise, you will understand how to break down a real-world scenario and apply key principles from your PE course.
欢迎来到 KS3 CIE 体育的案例分析实战演练。在本演练中，我们将遵循系统的方法，分析一位年轻运动员的表现，设定目标，设计训练计划并评估进展。通过本次练习，你将学会如何分解真实情境并运用体育课程中的关键原则。
1. Introduction to Case Studies in PE | 体育案例分析简介
Case studies in physical education allow you to apply theoretical knowledge to practical situations. They help you develop skills in observation, data analysis, planning, and evaluation. A typical case study involves examining an athlete's current fitness levels, identifying areas for improvement, and creating an action plan using training principles and SMART goals.
体育中的案例分析能让你将理论知识应用于实际情境。它们有助于培养观察、数据分析、计划和评估技能。典型的案例分析包括检查运动员当前的体能水平，确定需要改进的领域，并利用训练原则和 SMART 目标制定行动计划。
In this exercise, we will work with a fictional student named Amar. You will be guided through each step, from initial assessment to final recommendations. Think of yourself as a sports coach or a PE teacher helping Amar reach his potential.
在本练习中，我们将与一个虚构的学生 Amar 合作。你将从初始评估到最终建议逐步接受指导。把自己想象成一名体育教练或体育老师，帮助 Amar 发挥他的潜力。
2. Meet Our Athlete: Amar's Profile | 认识我们的运动员：Amar 的档案
Amar is a 14-year-old boy in Year 9. He enjoys football and sprinting and wants to improve his 100-metre sprint time. He currently runs the 100 m in 13.5 seconds. His goal is to break 12.5 seconds by the end of the school term so he can qualify for the junior athletics team. He trains twice a week during PE lessons and occasionally plays football with friends. He is generally healthy, with no injuries.
Amar 是一名 14 岁的九年级男生。他喜欢足球和短跑，希望提高 100 米短跑成绩。目前他 100 米跑成绩为 13.5 秒。他的目标是在学期末跑进 12.5 秒，以便入选青少年田径队。他每周在体育课上训练两次，偶尔和朋友踢足球。他身体状况良好，没有伤病。
Basic measurements: height 160 cm, weight 50 kg, body fat 15%. His strengths include good general endurance from playing football and excellent flexibility. However, his coach notices he has a slow start off the blocks and loses speed in the last 20 metres. He also lacks core strength, which affects his running posture.
基本数据：身高 160 厘米，体重 50 公斤，体脂率 15%。他的优势包括踢足球带来的良好一般耐力以及出色的柔韧性。然而，教练注意到他起跑慢，并且在最后 20 米掉速明显。他还缺乏核心力量，这影响了他的跑姿。
3. Identifying Strengths and Weaknesses | 识别优势与劣势
Before designing any training plan, we must assess Amar's strengths and areas for improvement. This helps us personalise his programme. We can use a simple SWOT-style analysis limited to performance-related factors.
在设计任何训练计划之前，我们必须评估 Amar 的优势和待改进领域。这有助于我们为他量身定制方案。我们可以使用简单的类 SWOT 分析法，仅关注与表现相关的因素。
Strengths: Good aerobic endurance (useful for recovery between sprints), high flexibility (reduces injury risk), strong motivation and willingness to train hard.
优势：良好的有氧耐力（有助于冲刺间的恢复）、高柔韧性（降低受伤风险）、强烈的动机和努力训练的意愿。
Weaknesses: Slow reaction time at the start, poor acceleration, lack of core stability, weak finishing speed, limited sprint-specific strength.
劣势：起跑反应慢、加速差、核心稳定性不足、终点速度弱、短跑专项力量有限。
Now list these in paired points:
现在以配对要点列出：
- Endurance: can sustain repeated efforts in training.
- 耐力：能在训练中维持反复的努力。
- Flexibility: allows a full range of motion for sprinting.
- 柔韧性：为冲刺提供充分的活动范围。
- Motivation: eager to follow a structured plan.
- 动机：渴望遵循结构化的计划。
- Start speed: takes 0.3 seconds longer to react than average peers.
- 起跑速度：比同龄人平均反应时间慢 0.3 秒。
- Core stability: weak plank hold (only 30 seconds), causing hip drop.
- 核心稳定性：平板支撑仅坚持 30 秒，导致髋部下坠。
- Finish speed: deceleration phase starts too early, around 70 m.
- 终点速度：减速阶段开始过早，在约 70 米处。
4. Applying SMART Goal Setting | 应用 SMART 目标设定
Now we help Amar set a goal using the SMART framework. SMART stands for Specific, Measurable, Achievable, Relevant, and Time-bound. This ensures the goal is clear and realistic.
现在我们帮助 Amar 使用 SMART 框架设定目标。SMART 代表具体、可衡量、可实现、相关和有时限。这确保目标清晰可行。
Specific: Improve 100-metre sprint time from 13.5 s to 12.5 s.
具体的：将 100 米短跑时间从 13.5 秒提高到 12.5 秒。
Measurable: Time trials every two weeks during
