📚 AS WJEC Physical Education: Case Study Practical Drill | AS WJEC 体育：案例分析实战演练

In AS WJEC Physical Education, the ability to apply theoretical knowledge to real-world scenarios is crucial. Case study analysis allows students to demonstrate understanding across physiological, psychological and sociocultural domains. This article presents a practical drill using a fictional athlete to guide you through the process of deconstructing a case and formulating evidence-based recommendations.

在 AS WJEC 体育课程中，将理论知识应用于真实情境的能力至关重要。案例分析使学生能够展示其在生理学、心理学和社会文化等领域的理解。本文将通过一个虚构运动员的实战演练，引导你一步步解构案例并制定基于证据的建议。

1. Understanding the Case Study Approach | 理解案例研究方法

WJEC AS Physical Education exams often present a case study of an athlete or team. The task is to identify strengths and weaknesses and propose interventions. You must consider factors from anatomy and physiology, sports psychology, and the socio-cultural context. A structured response using the PEE (Point, Evidence, Explain) framework is recommended.

WJEC AS 体育考试常常会给出一个运动员或团队的案例。任务是找出其优势与不足，并提出干预措施。你需要从解剖与生理学、运动心理学以及社会文化背景等方面考虑。建议使用 PEE（论点、证据、解释）框架进行条理清晰的回答。

Start by reading the case carefully and highlighting key information such as age, training history, recent performance data and any reported issues. Then categorize your observations into the three theoretical areas. This systematic approach ensures no critical point is missed.

首先要仔细阅读案例，标出年龄、训练史、近期表现数据以及任何报告的问题等关键信息。然后将你的观察归类到三个理论领域中。这种系统性的方法可以确保不会遗漏任何关键点。

2. Introducing Our Athlete: Sarah | 案例运动员介绍：Sarah

Sarah is a 17-year-old female sprinter specializing in the 200 m. Her personal best is 26.2 s, set last season. She trains four times a week but has recently plateaued and complains of fatigue and pre-race anxiety. Her coach reports that her start is powerful but she fades in the final 50 m. Sarah is in her final year of sixth form and aims to achieve a regional qualifying time of 25.5 s.

Sarah 是一名 17 岁的女子短跑运动员，专项 200 米。她的个人最好成绩是上赛季创造的 26.2 秒。她每周训练四次，但近期成绩停滞不前，并且抱怨疲劳和赛前焦虑。她的教练反馈说她的起跑很有力，但在最后 50 米速度下降明显。Sarah 正在读高中最后一年，目标是达到 25.5 秒的地区资格线。

3. Physiological Analysis | 生理学分析

The 200 m sprint predominantly relies on the ATP-PC system for the first 6–8 seconds and anaerobic glycolysis thereafter. Sarah’s fading in the final 50 m suggests insufficient anaerobic endurance or poor lactate clearance. Testing her blood lactate after a 200 m maximal effort would reveal her buffering capacity.

200 米短跑主要在前 6–8 秒依靠 ATP-PC 系统，之后则依赖无氧糖酵解。Sarah 在最后 50 米速度下降表明她的无氧耐力不足或乳酸清除能力较差。进行一次 200 米极限运动后的血乳酸测试可以揭示她的缓冲能力。

A key physiological factor is muscle fibre composition. Sprinters typically have a high percentage of fast-twitch (Type IIx) fibres. However, Type IIa fibres also contribute to sustained speed. Sarah may benefit from training that enhances the oxidative capacity of Type IIa fibres without detriment to speed. Additionally, her maximal heart rate is approximately 220 – 17 = 203 bpm, and rate of recovery should be monitored.

一个关键的生理因素是肌纤维组成。短跑运动员通常拥有高比例的快缩（Type IIx）纤维。然而，Type IIa 纤维也有助于维持速度。Sarah 或许能从增强 Type IIa 纤维氧化能力的训练中受益，同时不影响速度。此外，她的最大心率约为 220 – 17 = 203 bpm，并应监测其恢复速率。

Muscular strength and power are critical for acceleration. Assessing Sarah’s 1RM in back squat and her 30 m sprint time would provide baseline data. Any strength deficit could be linked to her slowing down in the latter part of the race. Core stability and hip extension power are also vital for maintaining sprint mechanics under fatigue.

肌肉力量与爆发力对加速至关重要。评估 Sarah 的后蹲 1RM 和 30 米冲刺时间可以提供基线数据。任何力量不足都可能与她在比赛后半程减速有关。核心稳定性与髋部伸展爆发力对于在疲劳状态下保持冲刺动作也十分关键。

4. Psychological Factors | 心理因素

Sarah’s pre-race anxiety can be examined using the Inverted-U theory. Moderate arousal improves performance, but excessive anxiety may cause her to tense up, impeding movement economy. Teaching her deep breathing and progressive muscle relaxation could help optimize her arousal level before a race.

可以用倒 U 理论来审视 Sarah 的赛前焦虑。适度的兴奋能提升表现，但过度焦虑可能导致她身体僵硬，影响动作经济性。教她进行
