ABSTRACT
With interval training, short to moderate periods of exercise are alternated with short to moderate periods of recovery. Research has demonstrated that athletes can undertake considerably more total work in a session if they alternate the short intense active bouts followed by recovery. The use of long slow distance (LSD) runs, cycles or swims involves performing exercise at a low intensity for durations longer than the competition event. One of the beliefs for this type of training is that improvements in endurance are proportional to the volume of training. In circuit training a series of different activities is performed in a given sequence. A circuit normally has at least six stations wherein the individual will exercise for a given period before resting and moving on. Improvements can be seen when the time taken to complete each station or the whole circuit is reduced.
