Exercise
Form 11: Biological Energy Systems
In this exercise, students will explore the different biological energy systems that power the human body, examining how aerobic and anaerobic processes produce energy during various physical activities. Through interactive diagrams and real-life examples, learners will deepen their understanding of how these systems interact to support endurance and strength training.
