The 20m Shuttle Run Test is one of the best methods for testing aerobic fitness and is suitable for athletes in active training, coaches with large groups to teach and people exercising to improve general well-being. It contains scores which have been obtained by a wide range of groups of children and adults. All you require is a CD player and two markers placed 20 metres apart. On the CD it is possible to repeat individual tracks quickly and with great precision. It also contains additional tracks for performing constant paced interval training and a sub-maximal aerobic test. 1997 | CD
