According to the literature, persons with intellectual disabilities have poor motor control in tasks in which motor anticipation is needed. Our study aimed to assess their motor behavior during interceptive tasks (a tennis ball interception with external-and-oneself throw conditions). A stick-bar was used as a reference or to support cloth to occlude a ball’s trajectory. Catch performance and interceptive behavior were analyzed (26 persons). The results show that high/low values of the initial approaching movement led to successful/successful catches, respectively. Our results are in line with the literature about the impact of poor motor control on performance in those with intellectual disabilities. We suggest that low anticipation may relate to problems in real-life situations.

根据文献，智障人士在需要运动预期的任务中运动控制较差。我们的研究旨在评估他们在拦截任务（具有外部和自己投掷条件的网球拦截）期间的运动行为。一根棍棒被用作参考或支撑布料以遮挡球的轨迹。对捕获性能和拦截行为进行了分析（26 人）。结果表明，初始接近运动的高/低值分别导致成功/成功的捕获。我们的结果与关于运动控制不佳对智障人士表现的影响的文献一致。我们认为低预期可能与现实生活中的问题有关。
