1. Cardiovascular System Essentials | 心血管系统核心术语
The cardiovascular system is the engine of performance. Knowing how heart rate, stroke volume, and cardiac output interrelate is fundamental to interpreting exercise physiology data.
心血管系统是运动表现的“引擎”。理解心率、每搏输出量和心输出量三者之间的相互关系是解读运动生理数据的基础。
- Heart Rate (HR): The number of ventricular contractions per minute, typically measured in beats per minute (bpm).
心率（HR）：每分钟心室收缩的次数，通常以次/分（bpm）为单位。 - Stroke Volume (SV): The volume of blood ejected by the left ventricle per beat. It increases with training due to cardiac hypertrophy.
每搏输出量（SV）：左心室每次搏动泵出的血量，训练后因心肌肥大而上升。 - Cardiac Output (Q̇): The total blood volume pumped by the heart per minute, calculated as HR × SV.
心输出量（Q̇）：心脏每分钟泵出的总血量，计算公式为 心率 × 每搏输出量。 - Bradycardia: A resting heart rate below 60 bpm, often seen in endurance athletes as a sign of efficient heart function.
心动过缓：静息心率低于60次/分，常见于耐力运动员，是心脏功能高效的表现。 - Venous Return: The flow of blood back to the heart; enhanced by the muscle pump and respiratory pump during exercise.
静脉回流：血液流回心脏的过程，运动中通过肌肉泵和呼吸泵的协同作用得到加强。
2. Respiratory System & Gaseous Exchange | 呼吸系统与气体交换
Efficient breathing mechanics and O₂/CO₂ exchange at the alveolar–capillary membrane determine an athlete's aerobic capacity. Terminology here links directly to VO₂ max and lung function tests.

潮气量（TV）：每次正常呼吸吸入或呼出的气体量，运动时显著增大。 - Minute Ventilation (V̇E): total volume of air moved into and out of the lungs per minute (TV × breathing frequency).
每分通气量（V̇E）：每分钟进出肺部的气体总量，等于潮气量×呼吸频率。 - VO₂ Max: The maximum volume of oxygen the body can utilise per minute per kilogram of body weight; the gold standard measure of aerobic fitness.
最大摄氧量（VO₂ Max）：每千克体重每分钟所能利用的最大氧量，是衡量有氧适能的黄金标准。 - Arteriovenous Oxygen Difference (a-vO₂ diff): The difference in oxygen content between arterial and venous blood, reflecting O₂ extraction by muscles.
