Assess students' understanding of the three primary bioenergetic systems (ATP‑PC, anaerobic glycolysis, oxidative phosphorylation), including their ATP production rate versus capacity, predominant substrates, typical time–intensity domains and transitions, metabolic byproducts (e.g., lactate), and implications for performance and recovery. Questions will ask learners to compare relative contributions across exercise durations and intensities (e.g., 0–10 s, 10–90 s, ~2–5 min, prolonged endurance), identify dominant system(s) for given activity profiles, and interpret simple scenarios or graphs of power output and metabolic responses.
