Assess students' understanding of aerobic and anaerobic exercise by testing knowledge of the primary energy systems (ATP-PCr, glycolytic, oxidative), key physiological responses (heart rate, VO2, lactate production/clearance, oxygen deficit/recovery, muscle fiber recruitment), and typical short-term training adaptations (changes in mitochondrial density, capillarization, lactate threshold, phosphocreatine stores, strength/power). Include application to common activity examples and interpretation of simple heart rate or lactate trends.
