The form of 3,684 throws made by 100 players in 7 collegiate baseball games was examined in relation to position, distance, and active and inactive situations. All throws made from the first pitch to the last out for 94 half innings were videotaped from the stands. The results showed that the interrater reliability of task, environment, and performance measures were all acceptable to excellent (percentage of agreement was at least 80%), indicating that qualitative aspects of throwing can be reliably measured in an actual sport context. Alternatives to the most advanced pattern were observed at least half the time for catchers and infielders at most distances in both active and inactive situations andfor pitchers and outfielders only in inactive situations.
研究了100名球员在7场大学棒球比赛中进行的3684次投球的形式，涉及位置、距离以及活跃和不活跃状态。从看台上对94个半局中从第一次投球到最后一次出局的所有投球进行了录像。结果表明，任务、环境和表现测量的评分者间信度均为可接受至优秀（一致率至少为80%），这表明在实际运动情境中可以可靠地测量投球的定性方面。在活跃和不活跃状态下，对于大多数距离的捕手和内场手，以及仅在不活跃状态下的投手和外场手，至少有一半时间观察到了最先进模式的替代模式。
