In football, which energy systems predominate for these actions: a short 10 m sprint, a longer break, and jogging to maintain position?

In football, which energy systems predominate for these actions: a short 10 m sprint, a longer break, and jogging to maintain position?

• A. Short sprint = aerobic; break = anaerobic glycolytic; jogging = ATP/PC
• B. Short sprint = ATP/PC; break = anaerobic glycolytic; jogging = aerobic
• C. Short sprint = anaerobic glycolytic; break = ATP/PC; jogging = aerobic
• D. Short sprint = aerobic; break = ATP/PC; jogging = anaerobic glycolytic

Answer: (B)

In football, the energy system that supplies the work matches how hard and how long you’re going. For a very short, all-out sprint, the body uses the ATP–PC (phosphocreatine) system. It provides quick energy without needing oxygen, but it gets used up in just a few seconds, so it’s the dominant source for that 10 m burst. If there’s a longer break between sprints, you’re still trading high-intensity effort with a period when you’re not fully at rest but not sprinting hard either. In that middle ground, the body relies more on anaerobic glycolysis to generate ATP quickly, which is why lactate can accumulate during these breaks. This is why the break is linked to anaerobic glycolysis rather than the ATP–PC system or the aerobic system. Jogging to maintain position is a steady, lower-intensity activity, where aerobic metabolism can supply the needed ATP efficiently using oxygen. This makes the aerobic system the predominant source during jogging. So the sprint pulls from ATP–PC, the break relies on anaerobic glycolysis, and jogging relies on the aerobic system.
