Which of the following is a method of anaerobic training?

Anaerobic intervals are a method of training that focuses on high-intensity efforts followed by short rest periods. This approach enables the body to work anaerobically, meaning it relies on energy sources that do not require oxygen. This type of training is designed to improve power, speed, and overall anaerobic capacity.

In anaerobic intervals, athletes might perform short bursts of intense activity, such as sprinting or heavy lifting, for a specific duration, followed by recovery periods. This strategy effectively enhances muscle strength and improves the ability to sustain high-intensity efforts.

Other options involve aerobic processes or less intense activities. Continuous running emphasizes endurance through sustained activity, which primarily relies on aerobic metabolism. Aerobic intervals also focus on improving cardiovascular endurance with moderate to high-intensity efforts, still operating mostly in the aerobic zone. Strength endurance circuits, while beneficial for strength-building, often include longer rest periods and moderate intensity, which lean more toward aerobic benefits rather than anaerobic adaptations. Thus, anaerobic intervals distinctly focus on maximizing short bursts of high-energy activity, making it the correct choice for anaerobic training.
