Relationship between twelve mechanic measures and score for national-level pistol shooters

The relationship between shooting mechanic measures and performance was determined by combining data from two pools. Eight national-level air-pistol athletes performed 60 simulated competition shots from each of four stance angles (0, 15, 30, and 45 degrees). A different pool of eight national-level shooters performed 60 simulated competition shots from each of two spine-to-arm angle positions (70 and 90 degrees). NOPTEL optoelectronic system was used to collect data for 12 mechanic measures from both pools.Analyzing data from two different pools by stepwise multiple regression identified the mechanic measures most effective in predicting adjusted score. Combining data from both pools and using a stepwise multiple regression analysis on all fired shots found similar results as that from the individual pools, p < 0.001, R2Adj = 0.41. The independent variables significantly related to performance were the shooting mechanic measures hold (COGf and COGr), hold accuracy (Hitr and Hitf), and time (HitHt and Total Time). NOPTEL mechanic measure, Hitr was the single most important criterion, accounting for 39% of the variation in adjusted score. These measures reflect important information that could be used when training with an optoelectronic system in conjunction with some system to capture score.
