摘要：This article describes the temporal characteristics of silent counting as used during a competition by the Russian youth team of synchronized swimmers. The athletes listened to the music that accompanied their performance at the competition. Diff erent indices of silent counting were defi ned, such as the beginning and cessation of diff erent periods of counting, counting frequency, the stability of the temporal structure of silent counting, the degree of synchronization of silent counting at diff erent moments during the sports program. We studied the relationship of these characteristics of counting with expert estimates of the athletes’ sense of tempo, coordination of movements, and choreographic abilities
