What type of training is characterized by alternating high-intensity and low-intensity periods?

Interval training is characterized by alternating high-intensity and low-intensity periods. This type of training involves short bursts of intense activity followed by rest or lower intensity, allowing for recovery while still maintaining a workout. The alternating periods can enhance cardiovascular endurance, speed, and overall fitness levels.

Continuous training, in contrast, involves sustained exercise without alternating intensity, focusing on maintaining a steady heart rate over a longer duration. Plyometric training emphasizes explosive movements and is not structured around alternating intensities, while strength training primarily focuses on resistance exercises that build muscle strength and size, rather than managing intensity through variations of activity.

Overall, interval training is unique in its structure and effectiveness for improving both aerobic and anaerobic fitness by incorporating varied intensity levels within a single workout session.
