Hello and thank you for showing interest in this new software, which assesses the aerobic fitness of children and adolescents based on age- and gender specific international norms.

I am Dr Stefan Kolimechkov and together with my colleagues Dr Petrov and Dr Alexandrova, and a computer engineer, we developed BeepShuttle Junior.

The software was presented at the 12th FIEP European Congress in Luxembourg in September 2017, and it can be applied for health and fitness screening, profiling, monitoring and surveillance in schools and sports clubs. A functional demo of the © BeepShuttle Junior is available for download here.

This is BeepShuttle Junior software, version 3.0, which was especially created to administer the 20m Shuttle Run Test in order to assess the cardiorespiratory fitness of children and adolescents by applying up-to-date international norms. This software implements the original 1-minute protocol described by Leger et al. [2], which starts at a speed of 8.5 km/h, and increases by 0.5 km/h each minute. BeepShuttle Junior calculates the predicted VO2max in individuals between the ages of 6 and 18, using the Leger et al.’s equation [3], and classifies them in accordance with a comprehensive and up-to-date set of gender-specific and age-specific international norms for children [4] and adolescents [5].


About the 20m Shuttle Run Test

The 20m Shuttle Run Test (20mSRT) was created by Luc Léger in 1982 and has been the most widely used test to assess aerobic fitness. The test is part of the most widely implemented health-related physical fitness test batteries [8], and can sometimes be found under different names, such as 20mSRT, multi-stage fitness test, PACER test, beep test, bleep test, etc. Nowadays, there are a few slightly modified protocols of the test, which are described in the literature, but the Leger et al.’s original 1-minute protocol is recommended [1].

During the test, children run between two lines, which are 20 metres apart, in time with an audio signal, and the test finishes when a child fails to reach the end lines simultaneously with the audio signals from the software on two consecutive occasions; otherwise, the test ends when a child stops due to fatigue [7].
