Assess learners' understanding of how aerobic and anaerobic exercise differentially engage the body's energy systems (ATP-PC, glycolytic, oxidative), alter acute and chronic heart rate responses and adaptations, and influence short- and long-term recovery strategies (active vs passive, metabolic replenishment, and training recovery principles). Include identification of exercise examples by intensity/duration, explanation of predominant metabolic pathways during various efforts, expected heart-rate patterns, and evidence-based recovery practices.
