Assessing test-retest reliability of the Newtest 2000® running speed measuring system
The aim of the present study is to measure the reliability of Newtest 2000 timing system. The Reliability of the Newtest 2000 timing system assessed by testing 52 Physical Education students.
Students aged (± SD) 21.4 (± 8.9). All participants were tested on 30 m sprint. Sprint performance and repeated sprint ability have been extensively described within male and female elite and non-elite athletes in different sports, as well as other healthy groups of people.
A number of measurement methods and equipment have been introduced, such as shuttle runs, straight forward acceleration and sprinting and treadmill testing.
In the literature, the majority used photocells, or light beams. Such applicable system for assessing sprint times is the Newtest 2000 Sprint timing system. However, the reliability of the system has yet to be verified.
The results from this investigation showed that the Newtest 2000 timing system is reliable testing instruments for testing Physical Education students and untrained subjects but not reliable enough to monitor the small changes in running speed that result from increasing the training of an already elite athlete. The system did not show any marked systematic bias (P < 0.05).
Furthermore, the testing system was found to useful instruments in measuring running speed. However, if comparison of overall values of running speed is intended, it is important to use the same testing system, because different systems give different results. It is also advisable to use this equipment only if no other gold standard equipment is available.
