1. Skeletal System Functions and Examples | 骨骼系统的功能与举例

Question: State two functions of long bones and give one example. This topic assesses your understanding of the skeletal system’s role in movement and physiology.

题目：说明长骨的两个功能并举例。该主题考查你对骨骼系统在运动和生理学中作用的理解。

Long bones like the femur act as rigid levers that muscles pull on to create movement at joints. This leverage function is crucial for all sporting actions, from kicking a ball to pushing off the starting block.

长骨（如股骨）充当刚性杠杆，肌肉牵拉长骨使关节产生运动。这种杠杆功能对所有运动动作至关重要，从踢球到起跑蹬地。

Additionally, long bones contain bone marrow, where red blood cells, white blood cells and platelets are produced. This haematopoiesis sustains oxygen delivery during prolonged exercise.

此外，长骨内含有骨髓，红细胞、白细胞和血小板在此生成。这种造血作用在长时间运动中维持氧气输送。

Model answer: 1. Movement (leverage); 2. Blood cell production. Example: femur (or humerus).

参考答案：1. 运动（杠杆作用）；2. 血细胞生成。例子：股骨（或肱骨）。

2. Cardiac Output and Exercise Response | 心输出量与运动反应

Question: Define cardiac output and describe how it changes during a 1500m run. Calculation-based questions appear frequently in Paper 1.

题目：定义心输出量并描述1500米跑时其变化。计算类题目在卷一中经常出现。

Cardiac output (Q) is the volume of blood pumped by the heart per minute, expressed as Q = stroke volume × heart rate. At rest, an untrained individual’s Q is around 5 L/min.

心输出量（Q）是心脏每分钟泵出的血量，表示为 Q = 每搏输出量 × 心率。安静时，未训练者的Q约为5升/分钟。

During a 1500m run, both heart rate and stroke volume increase significantly. Heart rate may rise from 70 bpm to near-maximal levels (around 180-200 bpm), while stroke volume increases due to stronger ventricular contractions and venous return. Consequently, cardiac output can reach 20–25 L/min, delivering more oxygen-rich blood to the working muscles.

在1500米跑中，心率和每搏输出量均显著增加。心率可能从70次/分升至接近最大水平（约180-200次/分），每搏输出量则因心室收缩增强和静脉回流增加而上升。因此，心输出量可达20–25升/分钟，将更多富氧血输送至工作肌肉。

3. Aerobic and Anaerobic Respiration | 有氧呼吸与无氧呼吸

Question: Compare aerobic and anaerobic respiration by giving two clear differences, including location within the cell and energy yield.

题目：比较有氧呼吸与无氧呼吸，给出两个明确区别，包括细胞内位置和能量产出。

Aerobic respiration requires oxygen and occurs in the mitochondria, producing carbon dioxide and water as by‑products. It yields approximately 36–38 ATP per glucose molecule, making it highly efficient for endurance activities.

有氧呼吸需要氧气，发生在线粒体中，副产物为二氧化碳和水。每分子葡萄糖可产生约36–38个ATP，因此对耐力活动非常高效。

In contrast, anaerobic respiration takes place in the cytoplasm without oxygen. It produces lactic acid and only 2 ATP molecules per glucose, leading to rapid fatigue. This system fuels short, high-intensity bursts such as sprinting or heavy weight lifting.

相比之下，无氧呼吸发生在细胞质中，不需氧气。它产生乳酸，每分子葡萄糖仅生成2个ATP，导致快速疲劳。该系统为短时高强度运动供能，如短跑或大重量举重。

4. Overload Principle and FITT | 超负荷原则与FITT

Question: Explain the principle of overload and outline how the FITT formula can be applied to improve aerobic fitness.

题目：解释超负荷原则，并概述如何运用FITT公式提升有氧体能。

The overload principle states that in order to improve, the body must be subjected to a greater than normal stress. Simply maintaining the same workout will lead to a plateau.

超负荷原则指出，为了取得进步，身体必须承受比平常更大的压力。保持相同训练只会导致停滞。

FITT stands for Frequency, Intensity, Time and Type. To improve aerobic fitness, a runner could increase training frequency from 3 to 4 sessions per week, raise intensity by running at 70–80% of maximum heart rate, extend time from 20 to 30 minutes, and choose a type such as continuous running or cycling.

FITT代表频率、强度、时间和类型。为提升有氧体能，跑者可将训练频率从每周3次增加到4次，强度提升至最大心率的70–80%，时间从20分钟延长到30分钟，并选择持续跑步或骑行等类型。

5. Health-Related Fitness Components and Testing | 健康相关体能成分与测试

Question: Identify two health-related fitness components and describe a standard fitness test for each.

题目：确定两个健康相关体能成分，并为每个描述一项标准体能测试。

Cardiovascular endurance, also called aerobic capacity, is the ability of the heart and lungs to supply oxygen to muscles during prolonged exercise. The multi-stage fitness test (bleep test) is a reliable field test where participants run between two lines in time with audio beeps that progressively increase in speed.

心血管耐力，亦称有氧能力，指在长时间运动中，心肺为肌肉供氧的能力。多阶段体能测试（哔哔测试）是可靠的现场测试，参与者根据逐渐加快的音频提示在两线间往返跑。

Flexibility is the range of movement possible around a joint. The sit and reach test, using a standard box, measures the flexibility of the lower back and hamstrings. A score of 30 cm or above is typical for active teenagers.

柔韧性是指关节周围可能的活动幅度。坐位体前屈测试使用标准测试箱，测量下背部和腘绳肌的柔韧性。活跃青少年通常能达30厘米或以上。

6. Nutrition: Carbohydrate Loading | 营养：碳水化合物加载

Question: What is carbohydrate loading and why is it used by marathon runners? Include timing and benefits.

题目：什么是碳水化合物加载？马拉松跑者为何使用它？请包括时机选择和益处。

Carbohydrate loading is a strategy used to maximise muscle glycogen stores before an endurance event. It involves tapering training and increasing carbohydrate intake to about 70–80% of total calories during the 3–4 days leading up to competition.

碳水化合物加载是在耐力赛事前提最大化肌糖原储存的策略。包括减少训练量，并在赛前3–4天将碳水化合物摄入提高到总热量的70–
