Assess students' understanding of acute cardiorespiratory responses (heart rate, stroke volume, cardiac output, ventilation, blood pressure, VO2 kinetics) and chronic adaptations (VO2max, resting/submaximal HR, stroke volume, blood/plasma volume, capillary and mitochondrial density, oxidative enzymes) to moderate‑intensity endurance training in college‑aged adults, including central vs peripheral mechanisms, typical time course, common assessment methods (GXT, HR zones, lactate threshold), and implications for training prescription and performance.
