Discovering any performance degradation effect of racing swimmers' use of social media smartphone apps might lead to new training and race preparation protocols, including pre-meet smartphone avoidance. This study's objective was to analyze the performance effects of using smartphone social media apps on the 50, 100, and 200-m freestyle among 25 high-level swimmers. Each participant performed the three race distances in two conditions: with smartphone app exposure (50-MF, 100-MF, and 200-MF) and without (50-CON, 100-CON, and 200-CON). We randomized the order of these two conditions across participants. While smartphone app use was not associated with statistically significant performance differences on the shortest race (50CON versus 50MF), a repeated measures ANOVA showed a significant condition × time interaction for the swimmers'100-m freestyle performance ( = 0.01), with a significantly slower performance following smartphone app use evident in the last half of this race ( = 0.02) but not in the first half ( = 0.41). We also found a condition × time interaction in the same direction (slower for swimmers who used the smartphone app) for the 200-m freestyle performance ( = 0.01), with the slower performance occurring in the second ( = 0.01) but not the first ( = 0.91), third ( = 0.07) or fourth ( = 0.06 quarters of this race. Thus, prolonged smartphone social media app use was associated with reduced performance from elite swimmers on the 100- and 200- but not the 50-m freestyle.
研究目的是分析 25 名高水平游泳运动员使用智能手机社交媒体应用程序对 50 米、100 米和 200 米自由泳成绩的影响。每位参与者在两种条件下完成这三个比赛距离：使用智能手机应用程序（50-MF、100-MF 和 200-MF）和不使用（50-CON、100-CON 和 200-CON）。我们随机安排了这两种条件在参与者之间的顺序。虽然智能手机应用程序的使用与最短比赛（50CON 与 50MF）的成绩没有统计学上的显著差异，但重复测量方差分析显示，在 100 米自由泳表现方面，条件与时间存在显著的交互作用（ = 0.01），在使用智能手机应用程序后，游泳者的成绩明显变慢（ = 0.02），但在前半段比赛中没有（ = 0.41）。我们还发现，在 200 米自由泳表现方面，也存在相同方向的条件与时间交互作用（使用智能手机应用程序的游泳者成绩变慢）（ = 0.01），在第二个（ = 0.01）但不是第一个（ = 0.91）、第三个（ = 0.07）或第四个（ = 0.06）四分之一比赛中，成绩变慢。因此，长时间使用智能手机社交媒体应用程序与精英游泳运动员在 100 米和 200 米自由泳比赛中成绩下降有关，但与 50 米自由泳比赛无关。
