在竞技短跑项目中，起跑和起跑加速环节占据着重要地位，对比赛的最终结果产生重要影响。问题是反应的开始时间（潜伏时间）在多大程度上对实现冲刺学科的结果有贡献。本研究的目的是确定十个世界锦标赛100 m、200 m、400 m决赛选手的反应时间与成绩表现之间的影响和联系。对参加锦标赛决赛（从 2001 年埃德蒙顿到 2019 年多哈）的总共 456 名决赛入围者（231 名男子）和 225 名（女子）选手的成绩进行了分析。起跑反应时间和冲刺成绩的评价依据的是国际田径联合会（IAAF）正式发布的报告。计算所有变量的中心参数和离散参数。使用皮尔逊相关系数计算反应时间与冲刺结果之间的关系，并通过简单回归分析确定反应时间对结果成功的直接影响，并计算统计显着性水平 p < 0.05 的相关系数。根据获得的结果，男性100 m短跑成绩的平均值与反应时间之间存在正相关但较低的相关性（r = 0.230p<0.044），回归分析也证实了这一点。在其他相关性和回归系数值中，在两类决赛入围者中都没有记录到反应时间对结果成功的影响的显着数值。
In athletic sprint disciplines, the segments of start and start acceleration occupy an important place that significantly generates the final outcome of the race. The question is to what extent the start time of the reaction (latent time) has a contribution to achieving the results of sprint disciplines. The aim of the current research was to determine the influence and connection between the reaction time and the result performance of running in the disciplines of 100 m, 200 m, 400 m finalists of ten world championships. The results of a total of 456 finalists (231 men) and 225 (women) competitors who competed in the final races of the championships (from Edmonton, 2001 to Doha, 2019) were analyzed. The evaluation of the start reaction time and sprint results was based on reports officially published by the International Association of Athletics Federation (IAAF). Central and dispersion parameters were calculated for all variables. The relationship between reaction time and sprint results was calculated using the Pearson correlation coefficient, and simple regression analysis determined the direct influence of reaction time on the result success and calculated the relevant coefficients for the level of statistical significance p < 0.05. Based on the obtained results, a positive but low correlation was recorded between the mean values of the 100 m sprint results and the reaction time in men (r = 0.230p<0.044), which was also confirmed by regression analysis. In other correlations and values of regression coefficients, no significant numerical values of the influence of reaction time on the result success were recorded in both categories of finalists.
