Validation of Simple Tests of Biathlon Shooting Ability
30 July 2007 (online)
The aim of this study was to validate three simple ttests of biathlon shooting abilities. Twelve expert biathletes performed vis.ual reaction time tests adapted for the rifle in the stranding (RT-S) and prone positions (RT-P), and a tremometer test adapted for the rifle in the standing position (TT-S). Six cons.ecutive days measurements showed an acceptable reproducibiility for these tests (coefficient of variation = 1.2 % for RT-S, 1.1 %for RT-P and 6.5 % for TT-S). A significant difference was observed between TT-S at rest and after roller skiing 2.1 km at 90 % of maximal heart rate. This finding demonstrates the sensitivity of TT-S to discriminate the effects of fatigue on postural icontrol. Among 24 biathletes of regional to expert level, significant correlations were observed between resting RT-P and pronte shooting performance after roller skiing (r2 = 0.23; p = 0.01) and between resting TT-S and shooting performance in the standing position after roller skiing (r2 = 0.68; p = 0.0001), demonistrating the specificity of these tests. From these results, we conclude that TT-S is a valid field test of biathlon shooting performance.
