What type of training involves a work period followed by a rest or recovery period?

Interval training is characterized by alternating periods of intense effort with periods of rest or lower intensity. This method is designed to improve both aerobic and anaerobic fitness, making it an effective way to enhance endurance and speed. The work periods can vary in duration and intensity, followed by recovery periods that allow the body to recuperate before the next burst of effort.

Continuous training, in contrast, involves sustained effort without rest periods, focusing on maintaining a steady heart rate for a longer duration. Static training typically involves holding a position, targeting flexibility or strength without the element of rest between efforts. Lastly, plyometric training focuses on explosive movements and does not follow a clear work-recovery pattern. Thus, interval training is distinct in its structure of alternating work and rest, making it particularly beneficial for improving performance in various sports and fitness activities.
