📚 Year 12 WJEC Physical Education: Case Study Practical Exercises | Year 12 WJEC 体育：案例分析实战演练
In Year 12 WJEC Physical Education, the case study component challenges you to think like a coach or sports scientist. It requires a holistic understanding of how physiological, psychological, and technical factors interact to influence performance. This article provides a step-by-step guide to tackling case study questions, using the practical example of a 16-year-old 800m runner, Ethan, who has hit a performance plateau.
在 Year 12 WJEC 体育中，案例分析部分要求你像教练或运动科学家一样思考。它需要全面了解生理、心理和技术因素如何相互作用影响表现。本文通过一位16岁800米跑运动员Ethan遇到表现瓶颈的实际案例，提供逐步破解案例问题的方法。
1. Understanding the Case Study Framework | 理解案例分析框架
WJEC case studies typically present a sporting scenario with an athlete struggling to improve. You are expected to identify the underlying issues, justify your analysis with theoretical knowledge, and propose a coherent action plan.
WJEC 的案例分析通常会给出一个运动员难以提高的体育场景。你需要找出潜在问题，用理论知识证明分析的正确性，并提出连贯的行动计划。
Marks are awarded for the application of concepts from anatomy, physiology, psychology, and sociocultural studies, not just for describing them. Always link theory directly to the case.
得分点在于运用解剖学、生理学、心理学和社会文化学中的概念，而不仅仅是描述它们。始终要将理论与案例直接联系起来。
2. Step 1: Performance Assessment & Needs Analysis | 第一步：表现评估与需求分析
Start by breaking down the case information: Ethan’s 800m time of 2:10, his complaints of persistent fatigue during interval sessions, and pre-race anxiety. Record relevant quantitative and qualitative data.
首先拆分案例信息：Ethan 的800米成绩为2分10秒，他在间歇训练中感到持续疲劳，赛前出现焦虑。记录相关的定量和定性数据。
A needs analysis determines the gap between current and desired performance. For an 800m runner, key areas include aerobic capacity, anaerobic power, lactate tolerance, pacing strategy, and mental resilience.
需求分析确定当前表现与目标表现之间的差距。对于800米跑运动员，关键领域包括有氧能力、无氧功率、乳酸耐受性、配速策略和心理韧性。
3. Step 2: Applying Exercise Physiology | 第二步：运用运动生理学
The 800m race depends approximately 60% on aerobic and 40% on anaerobic energy systems. Ethan’s fatigue suggests an underdeveloped aerobic base or poor lactate clearance. Assess his estimated VO₂ max and training heart rate zones using HRmax = 220 – age.
800米比赛约60%依赖有氧供能，40%依赖无氧供能。Ethan的疲劳暗示有氧基础不足或乳酸清除能力差。使用HRmax = 220 – 年龄公式评估他的估计最大摄氧量和训练心率区间。
HRmax = 220 – age
最大心率 = 220 – 年龄
For Ethan, age 16, HRmax ≈ 204 bpm. His aerobic training zone (70–80% HRmax) is 143–163 bpm. If he has not been training within this zone consistently, his aerobic engine will not improve.
对于16岁的Ethan，最大心率约为204 bpm。他的有氧训练区间（70–80% HRmax）是143–163 bpm。如果他未能持续在此区间训练，有氧能力就不会提高。
We can also compare energy system contributions through a simple table:
我们还可以通过一个简单的表格比较能量系统的作用：
| Energy System | Duration | Relevance to 800m |
|---|---|---|
| ATP-PCr (Phosphocreatine) | 0–10 sec | Start and final kick |
| Anaerobic Glycolysis | 10–90 sec | Middle 400–600m when oxygen demand exceeds supply |
| Aerobic System | > 90 sec | Entire race, recovery between surges |
Understanding this helps you explain why Ethan needs a combination of long slow runs and high-intensity intervals to develop both systems.
理解这一点有助于解释为什么Ethan需要长距离慢跑和高强度间歇训练相结合来发展两个系统。
4. Step 3: Psychological Factors & Interventions | 第三步：心理因素与干预
Ethan’s pre-race anxiety can be analysed with the Inverted-U Hypothesis: moderate arousal leads to optimal performance, but too much causes decline. He might lie on the right side of the curve, over-aroused.
Ethan的赛前焦虑可用倒U型假说分析：中等唤醒度带来最佳表现，但过高会导致表现下降。他可能处于曲线的右侧，处于过度唤醒状态。
Practical interventions include deep-breathing techniques, pre-performance routines, and cognitive restructuring to replace negative thoughts with positive self-talk. Setting SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound) also helps channel anxiety into focus.
实际的干预措施包括深呼吸技术、赛前例行程序和认知重构，用积极的自我对话取代消极想法。设定SMART目标（具体的、可衡量的、可实现的、相关的、有时限的）也有助于将焦虑转化为专注。
Explain that a sport psychologist might introduce imagery: Ethan visualises a perfect pacing strategy and a strong finish. This builds confidence and decreases perceived threat.
可以解释运动心理学家可能会引入意象训练：Ethan在脑海中想象完美的配速策略和有力的冲刺。这能建立信心并降低感知到的威胁。
5. Step 4: Technical & Tactical Analysis | 第四步：技术与战术分析
Technically, 800m runners must optimise stride length and frequency. Ethan may waste energy through excessive vertical oscillation or heel striking. Video analysis could highlight these inefficiencies.
在技术方面，800米跑运动员必须优化步幅和步频。Ethan可能因过度的垂直振幅或脚跟着地而浪费能量。视频分析可以揭示这些低效之处。
Tactically, even pacing often yields the best 800m times. If Ethan habitually goes out too fast in the first 200m, he will accumulate lactate prematurely. A negative split strategy (second lap faster) trains both physiological and psychological endurance.
战术上，匀速跑通常能产生最好的800米成绩。如果Ethan习惯在前200米跑得太快，他就会过早积累乳酸。负分段策略（第二圈更快）可同时训练生理和心理耐力。
Relate this to the case: you could suggest using a metronome or pacing lights during track sessions to develop an internal sense of pace.
将此与案例联系起来：你可以建议在跑道训练中使用节拍器或配速灯来培养内在的配速感。
6. Step 5: Designing a Periodised Training Programme | 第五步：设计周期化训练计划
Apply the FITT principle (Frequency, Intensity, Time, Type) within a periodised plan. For example, a macrocycle spanning six months, broken into mesocycles: base endurance, lactate threshold, speed endurance, and competition phases.
在周期化计划内应用FITT原则（频率、强度、时间、类型）。例如，一个为期六个月的大周期可划分为中周期：基础耐力期、乳酸阈值期、速度耐力期和比赛期。
A sample week in the lactate threshold mesocycle might include: 2 easy runs (40 min at 70% HRmax), 1 tempo run (20 min at 85% HRmax), 1 interval session (6 × 800m at goal race pace with 2 min rest), and 1 strength session focusing on plyometrics and core.
乳酸阈值中周期的一个示例周可能包括：2次轻松跑（40分钟，70% HRmax），1次节奏跑（20分钟，85% HRmax），1次间歇训练（6 × 800m，目标比赛配速，间歇2分钟），以及1次以增强式训练和核心力量为重点的力量课。
Justify why each session targets a specific adaptation. Intervals improve lactate buffering; tempo runs raise the lactate turnpoint. Always mention recovery days to prevent overtraining.
解释每节课为何针对特定适应：间歇训练提高乳酸缓冲能力；节奏跑提高乳酸转折点。始终要提及恢复日以防训练过度。
7. Step 6: Nutrition and Recovery Strategies | 第六步：营养与恢复策略
Ethan’s irregular diet likely contributes to fatigue. Recommend a balanced intake: 6–10 g/kg body mass of carbohydrates for endurance training, 1.2–1.7 g/kg of protein for repair, and adequate hydration.
Ethan不规律的饮食很可能是疲劳的原因之一。推荐均衡摄入：耐力训练每日每公斤体重6–10克碳水化合物，1.2–1.7克蛋白质以促进修复，以及充足的水分。
Pre-race meal should be high-carb, low-fat, consumed 3–4 hours before competition. Post-training, a 3:1 carbohydrate-to-protein ratio within 30 minutes accelerates glycogen resynthesis.
赛前餐应高碳水化合物、低脂肪，在比赛前3–4小时摄入。训练后30分钟内摄入3:1的碳水与蛋白质比例可加速糖原再合成。
Recovery strategies such as foam rolling, contrast water therapy, and 8–10 hours of sleep are not optional – they are essential for supercompensation. Link each recommendation back to Ethan’s symptoms.
泡沫轴放松、冷热水交替疗法和8–10小时睡眠等恢复策略不是可选的——它们是超量恢复所必需的。将每项建议都与Ethan的症状联系起来。
8. Step 7: Monitoring and Evaluation | 第七步：监测与评估
To determine if the plan works, use standardised fitness tests: the Cooper 12-minute run for aerobic improvement, the Wingate test for anaerobic power, and a 400m time trial for speed endurance.
为确定计划是否有效，可使用标准化体能测试：12分钟库珀跑测试有氧进步，Wingate测试评估无氧功率，400米计时赛评估速度耐力。
Subjective measures like the Rate of Perceived Exertion (RPE) and a training diary are equally important. They reveal how Ethan copes with load psychologically and physically.
主观测量，如自觉用力系数（RPE）和训练日记，同样重要。它们能揭示Ethan在心理和生理上如何应对负荷。
Propose a review schedule: every four weeks, re-test key metrics and adjust the training variables. This demonstrates a scientific, iterative approach that examiners reward.
提出一个评估时间表：每四周重新测试关键指标并调整训练变量。这体现出一种受到考官青睐的科学、迭代的方法。
9. Step 8: Structuring Your Answer – PEEL Method | 第八步：构建答案 – PEEL 方法
A well-structured answer uses the PEEL framework: Point – state your recommendation; Evidence – cite relevant theory or research; Explanation – explain why it applies to Ethan; Link – connect back to performance outcome.
结构良好的答案使用PEEL框架：Point – 提出建议；Evidence – 引用相关理论或研究；Explanation – 解释为何适用于Ethan；Link – 与表现结果联系。
For instance: ‘Ethan should incorporate tempo runs twice a week (Point). Research by Billat et al. shows that training at 85% HRmax improves lactate threshold (Evidence). This will allow Ethan to maintain a faster pace before significant lactate accumulation occurs, directly improving his 800m time (Explanation and Link).’
例如：“Ethan应每周进行两次节奏跑（Point）。Billat等人的研究表明，以85% HRmax训练可提高乳酸阈值（Evidence）。这将使Ethan在明显乳酸积累之前保持更快配速，直接提高800米成绩（Explanation and Link）。”
Using this method ensures your answer is logical and rooted in sport science, maximising marks.
使用此方法可确保你的答案逻辑严密并扎根于运动科学，从而最大化得分。
10. Common Pitfalls & Final Tips | 常见错误与最后提示
A common mistake is listing theories without linking them to the case. Saying ‘Ethan needs to improve his VO₂ max’ without explaining how, why, and what specific training will achieve it will not earn high marks.
一个常见错误是罗列理论却不与案例联系。只说“Ethan需要提高最大摄氧量”却不解释如何、为何提高以及哪种具体训练能达到目的，是不会得高分的。
Another pitfall is ignoring psychological or sociocultural factors. WJEC expects multi-faceted answers. For Ethan, mention that training with a partner could enhance motivation and reduce anxiety.
另一个陷阱是忽视心理或社会文化因素。WJEC期望多方面的答案。对于Ethan，可以提一下与伙伴一起训练可以提高动力并减少焦虑。
Finally, manage your time. Spend five minutes planning, ten minutes writing the case study response, and five minutes reviewing. A clear plan prevents rambling.
最后，要管理好时间。花五分钟计划，十分钟撰写案例分析回应，五分钟检查。清晰的计划能防止跑题。
