5×200

5x200 refers to a specific type of endurance swimming or running event. The "5" typically denotes the number of repetitions, and "200" indicates the distance of each repetition, usually measured in meters or yards. Therefore, a 5x200 event involves completing 200 meters or yards of swimming or running five times. This format is common in training programs and sometimes in competitive aquatic or track and field settings, particularly for middle-distance athletes or swimmers looking to build stamina and pace endurance.

In swimming, a 5x200 workout is often used to improve aerobic capacity and the ability to maintain a consistent pace over longer distances. Coaches might prescribe specific rest intervals between each 200-meter or yard swim, which can vary depending on the athlete's level and the training goal. For instance, longer rest periods might be used for building speed endurance, while shorter rest periods would focus more on cardiovascular conditioning. The stroke used for the 200-meter swims can also vary, with freestyle being the most common, but other strokes like backstroke, breaststroke, or butterfly might also be incorporated into a 5x200 set.

Similarly, in running, a 5x200 workout tests an athlete's ability to maintain a strong pace over a relatively short but repeated distance. This type of interval training is beneficial for developing speed endurance, which is crucial for events ranging from 400 meters to longer distances where maintaining a high speed for an extended period is necessary. The exact pace and rest periods for 5x200 running intervals would be tailored to the individual runner's training objectives, aiming to simulate race conditions or target specific physiological adaptations.
