For example, an athlete who has a poor change of direction capacity may not perform as well “aerobically” on the test in comparison to an athlete who has a good change of direction capacity (3). Variations of the test: Basketball (4), Wheelchair Basketball (5) and Ice Hockey (6)Īs expressed in the name, the 30-15 IFT is an ‘intermittent’ test, this means athletes are required to perform intense exercise followed by a recovery and repeat this until volitional exhaustion.Being used for training prescription (3).Identifying an athlete’s anaerobic velocity reserve (ARV) (3).Identifying an athlete’s repeated change of direction capacity (3).Identifying an athlete’s maximal aerobic speed (3).Since its original development, it has been diversified to do many different things. The ’30-15’ simply refers to the work-to-rest ratio/time – meaning the test requires athletes to run for 30-seconds and then recover (i.e. The 30-15 IFT consists of 30-second shuttle runs interspersed with 15-second walking recovery periods. first 30-second shuttle run), and this speed increases by 0.5 km/h for every 30-second stage thereafter. So, the running speed at stage 1 is 8km/h, stage 2 is 8.5km/h, stage 3 at 9km/h and so on.Īthletes are required to run back and forth between the two lines set 40-metres apart (Figure 1) at a speed governed by an audio “beep”. As the individual progresses through the levels, the time between the beeps decreases giving the individual less time to complete each shuttle, thus increasing the speed/intensity of the test. The two 3-metre zones in the middle of the testing area (6-metres in total) exist so that the athletes can gauge the required running speed, and therefore adjust their speed accordingly (i.e. The two 3-metre end zones/turning lines also help guide the athlete to adjust/maintain their speed. During the 15-second recovery period, athletes are required to walk in a forward direction towards the closest 3-metre zone this zone is where they will start the next running stage from.Īthletes must reach the next 3-metre zone – either the middle one or the end zones – on a consistent basis. Participants begin the test from the ‘start-line’ (Zone A).Failure to reach the next 3-metre zone on three consecutive occasions results in elimination from the test.
