Is simply training in which an athlete alternates between two or more activities, typically requiring different rates of speed and degrees of effort. Like high-intensity exercise workouts interspersed with rest or relief periods. For example a sprinter who sprints 100 yds. Then walks back to his/her’s starting point (a rest period) then begins the sprints again.
