1. Joint Analysis: The Knee in a Soccer Kick | 关节分析：足球踢球时的膝关节
Mock Question: Describe the joint action at the knee during the leg swing of a soccer instep kick. Name the joint type, the movement, the agonist muscle, and the contraction type. (4 marks)
模拟题： 描述足球脚背踢球时摆腿阶段的膝关节动作。指出关节类型、运动方式、主动肌及收缩类型。（4分）
The knee is a synovial hinge joint, permitting flexion and extension. As the leg swings forward to strike the ball, the knee rapidly extends. The agonist producing this extension is the quadriceps group, specifically the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The contraction is concentric isotonic, because the muscle shortens while generating tension.
膝关节是滑膜铰链关节，只允许屈和伸。摆腿向前击球时，膝关节快速伸展。产生伸展动作的主动肌是股四头肌群，包括股直肌、股外侧肌、股内侧肌和股中间肌。收缩类型为向心等张收缩，因为肌肉在产生张力时缩短。
Many students lose a mark by naming only ‘quadriceps’ without specifying the individual muscles, or by confusing the contraction type with an eccentric action that would occur if the leg were decelerating. Always check the phase of the movement: the knee flexes eccentrically to store energy in the backswing, then extends concentrically in the forward swing.
不少学生因只写’股四头肌’而未点名具体肌肉，或将收缩类型误答为离心收缩而丢分——离心收缩多出现在减速阶段。务必核对动作阶段：后摆时膝关节离心屈曲蓄能，前摆时向心伸展释放。
2. Muscle Contraction Types: Jumping and Landing | 肌肉收缩类型：跳跃与落地
Mock Question: A basketball player jumps for a rebound and then lands. Compare the types of muscle contraction occurring in the quadriceps during the take-off and the landing. (3 marks)
模拟题： 篮球运动员跳起抢篮板并落地。比较起跳和落地两个阶段股四头肌发生的收缩类型。（3分）
During the take-off, the knee extends from a flexed position. The quadriceps shorten under tension, producing a concentric isotonic contraction that drives the body upwards. In the landing phase, the quadriceps lengthen while still generating force to control the downward movement. This is an eccentric isotonic contraction, which acts as a braking mechanism to absorb impact and prevent injury.
起跳时，膝关节由屈到伸，股四头肌在张力下缩短，产生向心等张收缩，将身体向上推起。落地阶段，股四头肌在持续用力的同时被拉长，完成离心等张收缩，起到缓冲减速、吸收冲击力并预防受伤的作用。
A frequent error is to label both phases as concentric. Remember that whenever a muscle lengthens under tension, it is eccentric. Landing requires eccentric control; without it, the athlete would collapse. Also note that an isometric contraction – where the muscle length stays constant – might occur if the player holds a stable crouched position momentarily.
常见错误是把两个阶段都说成向心收缩。记住，肌肉在张力下被拉长即离心收缩。落地必须有离心控制，否则运动员会直接扑倒。还需留意，等长收缩（肌肉长度不变）可能出现在球员短暂保持下蹲姿态时。
3. Cardiovascular Responses to Exercise | 心血管系统对运动的反应
Mock Question: Explain how heart rate and stroke volume change as a cyclist moves from rest to high-intensity cycling, and use these to calculate cardiac output. (5 marks)
模拟题： 解释自行车运动员从安静状态进入高强度骑行时，心率和每搏输出量如何变化，并据此计算心输出量。（5分）
At rest, heart rate (HR) is around 70 bpm and stroke volume (SV) is approximately 70 ml. As exercise intensity increases, HR rises linearly up to a maximum dictated by age. Stroke volume also increases due to enhanced venous return and more forceful ventricular contraction, but it plateaus at about 40–60% of VO₂ max. Cardiac output (Q) is the product of HR and SV. The formula is:
安静时心率约 70 bpm，每搏输出量约 70 ml。随运动强度增加，心率呈线性上升，直至年龄决定的最大值。每搏输出量因静脉回流量增加和心室收缩更有力而升高，但会在达到 VO₂ max 的 40–60% 时趋于平台。心输出量 (Q) 是心率与每搏输出量的乘积，公式为：
Q = HR × SV
Therefore, at moderate intensity HR might be 150 bpm and SV 120 ml, giving a Q of 18,000 ml/min (18 L/min). A well-trained athlete can increase SV further, giving a higher cardiac output for the same heart rate. Students often forget to convert millilitres to litres or confuse the plateau of stroke volume with a decline.
因此，在中等强度下心率可达 150 bpm，每搏输出量为 120 ml，心输出量即为 18,000 ml/min（18 L/min）。训练有素的运动员能进一步提高每搏输出量，使同等心率时心输出量更大。学生常忘记毫升与升的换算，或将每搏输出量的平台现象误认为下降。
4. Respiratory System Mechanics: Intercostals and the Diaphragm | 呼吸系统机制：肋间肌与膈肌
Mock Question: Outline the role of the external intercostal muscles and the diaphragm during inspiration at the start of a 1500 m race. (4 marks)
模拟题： 简述 1500 米赛跑起跑前的吸气过程中，肋间外肌和膈肌的作用。（4分）
At the start of exercise, deeper and faster inspiration is required. The diaphragm contracts and flattens, moving downwards to increase the vertical volume of the thoracic cavity. Simultaneously, the external intercostal muscles contract, pulling the rib cage upwards and outwards, which increases the lateral and anterior-posterior dimensions of the chest. This expansion reduces the intra-thoracic pressure below atmospheric pressure, causing air to rush into the lungs.
运动开始时，需要更深更快的吸气。膈肌收缩变平并下移，增加胸腔的垂直容积。同时，肋间外肌收缩，将胸廓向上向外提拉，增加胸腔的侧向和前后径。这种扩张使胸内压低于大气压，空气迅速进入肺部。
During forced expiration later in the race, the internal intercostal muscles and abdominal muscles become more active, but inspiration at the start relies on the primary inspiratory muscles. A mark-losing mistake is to refer to the ‘intercostals’ without specifying external or internal; they perform opposite roles.
比赛中后期用力呼气时，肋间内肌和腹肌会更活跃，但起跑前的吸气主要依赖吸气主肌。扣分点是只写’肋间肌’而不区分肋间外肌和肋间内肌，二者作用恰好相反。
5. Classification of Movement Skills | 运动技能分类
Mock Question: Classify a tennis serve according to the continua of open–closed, gross–fine, and discrete–serial–continuous. Justify each choice. (3 marks)
模拟题： 根据开放—闭锁、粗大—精细以及分立—序列—连续三个连续体对网球发球进行分类，并逐项说明理由。（3分）
A tennis serve is predominantly a closed skill because it is performed in a stable, predictable environment where the performer initiates the action. It is a gross motor skill, as it involves large muscle groups and whole-body coordination. In terms of patterning, the serve is a discrete skill with a clear beginning (the toss) and end (ball contact). However, in a match it could be seen as part of a serial routine (ball bounce, toss, strike).
网球发球主要属于闭锁技能，因为它在一个稳定、可预测的环境中完成，由运动员自己启动动作。它属于粗大动作技能，因为需要大肌肉群和全身协调。从动作模式看，发球是分立技能，有明确的开始（抛球）和结束（击球）。但在比赛中也可视为序列动作的一部分（拍球、抛球、击球）。
Students often misclassify the serve as open because the opponent’s position might influence placement, but the environment remains stable, and the server controls the timing. Clarifying the continuum definitions is key: open skills are adapted to a changing environment, while closed skills are self-paced.
学生常因对方站位可能影响落点而误将发球归为开放技能，但发球环境稳定，且由发球方控制节奏。厘清连续体定义是关键：开放技能需适应变化的环境，闭锁技能则是自定节奏的。
6. Information Processing: Whiting’s Model Applied | 信息加工：应用 Whiting 模型
Mock Question: Use Whiting’s information processing model to explain how a goalkeeper encodes the ball’s flight in a penalty kick. (6 marks)
模拟题： 运用 Whiting 的信息加工模型，解释足球守门员在点球时如何编码球的飞行路线。（6分）
Whiting’s model describes the sequence from input to output. First, the goalkeeper receives exteroceptive cues from the display, such as the ball’s trajectory, the kicker’s body language and run-up angle. These are detected by the visual and auditory receptor systems. Perceptual mechanisms filter and interpret this information, assessing speed and direction. The translatory mechanisms then use this perception to formulate a motor programme, selecting the appropriate dive. The effector mechanism sends impulses via the motor nerves to the muscles, producing the diving save. Feedback, both intrinsic (proprioception) and extrinsic (coach’s comments), evaluates the outcome.
Whiting 模型描述了从输入到输出的序列。首先，守门员从展示环境中接收外部感受线索，如球的飞行轨迹、罚球队员的身体语言和助跑角度。这些信息由视觉和听觉感受器系统探测。知觉机制筛选并解读信息，评估球速和方向。随后，转换机制利用知觉形成运动程序，选择合适的扑救方案。效应器机制通过运动神经将冲动传至肌肉，完成扑救动作。反馈包括内在反馈（本体感觉）和外在反馈（教练评价），用于评估结果。
A common exam slip is to omit the translatory stage or to confuse it with the effector mechanism. Marks are also awarded for naming specific cues; generic answers miss the application. Always relate the model to the sporting context.
考试中常见失误是遗漏转换阶段或将其与效应器机制混淆。说出具体的线索信息也能得分；泛泛而谈就脱离了情境。务必将模型与运动场景联系起来。
7. Reaction Time, Movement Time and Hick’s Law | 反应时、运动时与希克定律
Mock Question: A fencer responds to an opponent’s lunge by parrying. Define reaction time and movement time, and explain how Hick’s Law can affect the response. (4 marks)
模拟题： 击剑运动员对对手的弓步进攻做出格挡。定义反应时和运动时，并解释希克定律如何影响该反应。（4分）
Reaction time is the interval between the onset of a stimulus (the opponent’s forward movement) and the initiation of the performer’s response (start of the parry). Movement time is the duration from the beginning of the response to its completion (the blade completing the parry). Response time = reaction time + movement time. Hick’s Law states that reaction time increases linearly as the number of stimulus–response alternatives grows. If the opponent can lunge to multiple targets, the fencer’s choice reaction time lengthens, potentially delaying the parry.
反应时是指从刺激出现（对手前移）到应答动作启动（开始格挡）之间的时间间隔。运动时则是从应答开始到完成（剑身完成格挡）所耗费的时间。反应时与运动时之和为响应时。希克定律指出，随着刺激—反应选项数量的增加，反应时呈对数线性增长。若对手可能攻击多个部位，击剑者的选择反应时就会延长，可能导致格挡延迟。
To counter this, coaches reduce uncertainty through false starts or pattern training, making the response more like a simple reaction. Students often mistake reaction time for movement time or forget to calculate response time. Remember, a broad range of attack options increases decision time.
为应对这种情况，教练会通过假动作或套路训练来减少不确定性，使反应更接近简单反应。学生常混淆反应时与运动时，或忘记计算响应时。请记住，攻击选项越多，决策时间越长。
8. Principles of Training: FITT Applied to Sprinters | 训练原则：FITT 应用于短跑运动员
Mock Question: Design a one-week training schedule for a 100 m sprinter using the FITT principle. Specify frequency, intensity, time, and type for a power-based session. (4 marks)
模拟题： 利用 FITT 原则为一名 100 米短跑运动员设计一周训练计划，针对爆发力训练课说明频率、强度、时间和类型。（4分）
Frequency: 3 sessions per week dedicated to power development, allowing 48 hours between sessions for recovery. Intensity: 85–95% of one-repetition maximum (1RM) in plyometric and weight training, or maximal effort in sprint drills. Time: 30–45 seconds of work with full recovery (120 seconds) for true alactic power; a session may last 45–60 minutes. Type: explosive exercises such as bounding, depth jumps, and Olympic lifts like power cleans, combined with short sprint starts.
频率：每周 3 次爆发力训练课，课间间隔 48 小时以利恢复。强度：采用 1RM 的 85–95% 进行增强式训练和负重训练，或在短跑专项练习中用最大努力。时间：每次练习持续 30–45 秒，组间充分恢复（120 秒），属于典型的非乳酸功率训练；一堂课总共 45–60 分钟。类型：爆发性练习如跨步跳、跳深和奥林匹克举重（高翻），配合短距离冲刺起跑。
A major error is to prescribe too little rest or too high a volume, turning a power session into an endurance session. Also, the FITT principle must show progression and overload across weeks; a single week is a snapshot, but students should mention how intensity would gradually increase. Never confuse time (duration of effort) with total session time.
常见错误是安排的休息不足或训练量过大，导致爆发力课变成耐力课。此外，FITT 原则需体现渐进超负荷；学生虽只需呈现一周计划，但应说明强度会逐步提升。切勿将练习时间（努力时长）与整堂课的总时间混淆。
9. Sport and Society: Barriers to Participation | 运动与社会：参与障碍
Mock Question: Identify three socio-economic barriers to participation in golf and suggest a practical solution for each. (6 marks)
模拟题： 指出高尔夫运动参与的三项社会经济障碍，并为每项障碍提出一个可行的解决方案。（6分）
Barrier 1: High cost – green fees, equipment, and membership fees make golf inaccessible for lower-income groups. Solution: local councils could offer subsidised driving-range sessions or equipment hire schemes to reduce the financial burden.
障碍一：高费用——果岭费、装备和会籍费使低收入群体难以参与高尔夫。解决方案：地方政府可以提供补贴的练习场时段或器材租赁计划，减轻经济负担。
Barrier 2: Time constraints – an 18-hole round takes 4–5 hours, which conflicts with shift work or family responsibilities. Solution: promote shorter formats like 9-hole or par-3 courses that fit busy schedules.
障碍二：时间限制——打一场 18 洞需 4–5 小时，与轮班工作或家庭责任冲突。解决方案：推广更短的形式，如 9 洞或三杆洞球场，适应紧凑的日程。
Barrier 3: Social exclusion – golf is often perceived as a middle-class, male-dominated sport, deterring ethnic minorities and women. Solution: run targeted outreach programmes, women-only coaching sessions, and use role models from diverse backgrounds to widen appeal.
障碍三：社会排斥——高尔夫常被视为中产阶级、男性主导的运动，令少数族裔和女性望而却步。解决方案：开展定向推广项目、专设女性教练课程，并借助多元背景的榜样扩大吸引力。
10. Ethics and Performance-Enhancing Drugs | 伦理与兴奋剂
Mock Question: Discuss the ethical and physiological reasons why anabolic steroids are banned in sport. (4 marks)
模拟题： 论述禁止在体育中使用合成代谢类固醇的伦理和生理原因。（4分）
Anabolic steroids mimic testosterone, increasing protein synthesis and muscle mass beyond natural training limits. Physiologically, they lead to severe side effects such as liver damage, cardiovascular disease, and endocrine disruption – for example, reduced natural testosterone production and testicular atrophy. Ethically, their use violates the spirit of fair play by giving an artificial advantage and undermining the principle of equal opportunity. Drug use also sets a dangerous example for young athletes, normalising cheating as a shortcut to success.
合成代谢类固醇可模拟睾酮，提升蛋白质合成，使肌肉增长超越自然训练极限。生理上，它会导致肝损伤、心血管疾病和内分泌紊乱等严重副作用，例如天然睾酮分泌减少和睾丸萎缩。伦理上，使用兴奋剂违背公平竞争精神，人为制造优势，破坏机会均等原则。用药还会给青少年运动员树立危险榜样，使作弊被视为成功的捷径。
Students often list only the physiological harms and forget the ethical dimension. For top marks, link the physical risks to the concept of athlete welfare, which is central to anti-doping policies. The World Anti-Doping Code bans substances that pose health risks and contradict the ‘spirit of sport’.
学生常仅罗列生理危害而遗漏伦理维度。想要拿到高分，必须将身体风险与运动员福祉理念挂钩，这是反兴奋剂政策的核心。世界反兴奋剂条例禁止那些危害健康且违背’体育精神’的物质。
