Step 1
Identify the dominant energy systems for different events
Answer
In athletics, various events rely on different energy systems. The 100-metre sprint primarily uses the anaerobic energy system due to its short duration. The 400-metre run also uses anaerobic pathways but to a lesser extent due to its longer duration.
High-jumpers primarily rely on explosive strength and speed, using both anaerobic and aerobic systems. However, the 1500-metre swimming event, which is longer and demands sustained effort, predominantly utilizes the aerobic energy system.
