1. Overview of the Mock Test | 模拟测试卷概览
The mock test consists of 25 marks in total, divided into three sections: multiple‑choice, short‑answer, and data‑interpretation questions. It covers the human body's response to exercise, factors affecting performance, and the application of training theory. The time allowed is 40 minutes.
模拟卷总分 25 分，分为三个部分：选择题、简答题和数据解读题。内容覆盖人体对运动的反应、影响运动表现的因素以及训练理论的应用。考试时间为 40 分钟。
2. Question 1: Heart Rate and Exercise Intensity | 第 1 题：心率与运动强度
Question: A 15‑year‑old performer has a maximum heart rate (MHR) of 205 bpm. Calculate the target heart rate zone for 60–80% intensity.
题目：一名 15 岁的运动员最大心率 (MHR) 为 205 bpm。计算 60–80% 强度下的目标心率区间。
Answer: Lower limit = 205 × 0.60 = 123 bpm; Upper limit = 205 × 0.80 = 164 bpm. The target zone is 123–164 bpm. This range ensures cardiovascular improvement while minimising overtraining risk.
答案：下限 = 205 × 0.60 = 123 bpm；上限 = 205 × 0.80 = 164 bpm。目标区间为 123–164 bpm。该范围在确保心血管改善的同时可降低过度训练风险。
3. Question 2: Types of Muscle Contractions | 第 2 题：肌肉收缩类型
Question: Describe an isometric contraction and give a sporting example.
题目：描述等长收缩并给出一个运动实例。
Answer: An isometric contraction occurs when the muscle generates force without changing length, so no visible movement happens at the joint. Example: holding a plank position during core training. The rectus abdominis contracts statically to stabilise the spine.
答案：等长收缩指肌肉产生力量但长度不变，关节处不发生可见运动。例如：核心训练中保持平板支撑姿势，腹直肌静态收缩以稳定脊柱。
4. Question 3: Anaerobic and Aerobic Respiration | 第 3 题：无氧呼吸与有氧呼吸
The question required learners to compare the two energy pathways. Key comparisons are shown in the table below.
题目要求比较两种能量通路。下表列出关键比较点。
| Feature / 特征 | Aerobic / 有氧 | Anaerobic / 无氧 |
|---|---|---|
| O₂ required / 需氧 | Yes / 是 | No / 否 |
| Fuel / 燃料 | Carbohydrates, fats / 糖、脂肪 | Carbohydrates only / 仅糖 |
| Duration / 持续时间 | Long ( > 2 min) / 长（> 2 分钟） | Short ( ≤ 90 s) / 短（≤ 90 秒） |
| By‑product / 副产物 | CO₂, H₂O / CO₂、水 | Lactic acid / 乳酸 |
Anaerobic respiration provides rapid ATP for high‑intensity bursts, while aerobic respiration sustains prolonged activities.
无氧呼吸为高强度爆发提供快速 ATP，而有氧呼吸则维持长时间活动。
5. Question 4: Principles of Training | 第 4 题：训练原则
Question: Explain how a coach can apply the principle of progressive overload to a 400‑m runner.
题目：解释教练如何对 400 米跑运动员运用渐进超负荷原则。
Answer: Progressive overload requires gradually increasing the training stimulus to continue improving fitness. For a 400‑m runner, the coach might increase the distance at race pace by 10% every two weeks, or reduce recovery intervals between repetitions. This forces the anaerobic system to adapt without causing injury.
答案：渐进超负荷要求逐步增加训练刺激以持续提升体能。对 400 米跑运动员，教练可每两周增加 10% 的比赛配速距离，或缩短重复跑之间的恢复间隔。这会迫使无氧系统适应，同时避免受伤。
6. Question 5: Flexibility Testing – Sit and Reach | 第 5 题：柔韧性测试——坐位体前屈
Question: Outline the standard protocol for the sit‑and‑reach test and identify one limitation.
题目：简述坐位体前屈测试的标准流程并指出一个局限性。
Answer: The performer sits with legs straight against a box, reaches forward with hands overlapped, and pushes the slider as far as possible without jerking. The best of three attempts is recorded. Limitation: the test mainly measures hamstring and lower‑back flexibility and does not reflect whole‑body flexibility.
答案：受试者坐姿，双腿伸直抵住测试箱，双手重叠前伸，平稳推动滑块至最远。取三次尝试中的最佳值。局限性：该测试主要测量腘绳肌和下背部柔韧性，不能反映全身柔韧性。
7. Question 6: Skeletal System and Joint Movements | 第 6 题：骨骼系统与关节动作
Question: Name the joint action occurring at the knee when kicking a ball, and identify the agonist muscle group.
题目：指出踢球时膝关节发生的关节动作，并确定主动肌群。
Answer: The action is knee extension. The quadriceps group acts as the agonist, contracting concentrically to straighten the leg. The hamstrings act as the antagonist, relaxing to allow the movement.
答案：动作为膝关节伸展。股四头肌群作为主动肌进行向心收缩以伸直腿部。腘绳肌作为拮抗肌放松，以允许该运动。
8. Question 7: Nutrition and Hydration | 第 7 题：营养与水分补充
Question: Suggest a pre‑event meal for a gymnast competing at 10 a.m. and justify your choice.
题目：为上午 10 点比赛的体操运动员推荐一份赛前餐，并说明理由。
Answer: A suitable meal could be porridge with a banana and water, consumed 2–3 hours before the event. The porridge provides slow‑release carbohydrates to maintain blood glucose, the banana supplies potassium for nerve function, and water ensures hydration. The meal is low in fat and fibre to avoid digestive discomfort during performance.
答案：合适的餐食为燕麦粥配香蕉和水，赛前 2–3 小时食用。燕麦粥提供缓慢释放的碳水化合物以维持血糖，香蕉提供钾支持神经功能，水确保水分。该餐脂肪和纤维含量低，避免比赛时消化不适。
9. Question 8: Interpreting a Training‑Session Heart‑Rate Graph | 第 8 题：解读训练课心率图
Question: The graph shows a performer's heart rate during a 30‑minute session: warm‑up (0–5 min, rise to 120 bpm), main activity (5–20 min, fluctuating 155–175 bpm), cool‑down (20–30 min, gradual decline to 100 bpm). Explain what the heart‑rate changes indicate about exercise intensity and recovery.
题目：图表显示一名运动者 30 分钟训练课的心率：热身（0–5 分钟，升至 120 bpm），主体活动（5–20 分钟，在 155–175 bpm 间波动），整理（20–30 分钟，逐渐降至 100 bpm）。解释心率变化反映了怎样的运动强度和恢复情况。
Answer: The warm‑up gradually raises heart rate, preparing the cardiovascular system. The main activity heart rate of 155–175 bpm indicates work within 75–85% of estimated MHR, confirming vigorous aerobic intensity. The cool‑down decline shows effective recovery, though a resting value of 100 bpm suggests the performer has not fully returned to baseline, emphasising the need to extend the recovery phase.
答案：热身阶段心率逐步升高，为心血管系统做准备。主体活动心率 155–175 bpm 表明运动强度在估计最大心率的 75–85%，确认为高强度有氧负荷。整理阶段心率下降显示有效恢复，但最终 100 bpm 的静息值表明运动员尚未完全回到基础水平，提示需要延长恢复阶段。
10. Summary and Final Tips | 总结与最终建议
To succeed in the SQA Physical Education unit test, you must command factual recall, understand 'Explain' and 'Describe' command words, and practise reading graphs. Always link physiological principles to sporting examples. Review your mock test answers, identify gaps, and use active revision techniques.
要在 SQA 体育单元测试中取得成功，你需要掌握事实记忆、理解“解释”和“描述”等指令词，并练习解读图表。始终将生理学原理与运动实例联系起来。回顾你的模拟卷答案，找出薄弱环节，并采用主动复习技巧。
