The effect of prohibiting the use of a preshot routine on free-throw shooting in competitive situations was investigated. 25 male high school basketball players were instructed to attempt 50 free throws alternating in blocks of 10 between the use of their preshot routine and shooting without it. To make the situation competitive, subjects were run in groups of five and their performance was recorded on a large easel placed to the side of the free-throw line. A significantly larger number of baskets were made in the preshot routine condition than without the routine. A competitive situation led to a greater decrement in baskets than had been reported in 1986 by Lobmeyer and Wassermen during noncompetitive free-throw shooting.
研究了在比赛情境中禁止使用罚球前常规动作对罚球投篮的影响。25名男性高中篮球运动员被要求进行50次罚球，在使用罚球前常规动作和不使用罚球前常规动作之间交替进行，每次10次罚球为一组。为了营造比赛氛围，将受试者分成五人一组进行测试，并将他们的表现记录在罚球线一侧放置的大画架上。与不使用常规动作相比，使用罚球前常规动作时命中的篮筐数量显著更多。与1986年洛布迈尔和沃瑟曼在非比赛罚球投篮中所报告的情况相比，比赛情境导致命中篮筐数量的下降幅度更大。
