Individual differences and similarities in the stability, timing consistency, and natural frequency of rhythmic coordinated actions.

摘要: Under preferred speed conditions, 15 adults undertook bimanual in-phase and antiphase tapping, clapping, galloping, galloping while crawling on their hands feet. We measured stability of interlimb coordination (standard deviation mean relative phasing), single limb timing consistency (coefficient variation cycle durations), natural frequency. Pearson product-moment correlations among tasks established that only the frequencies were significantly correlated (specifically gross motor actions in which larger contributions inertial loads contribute to frequencies). Intraclass high for tasks, meaning within each task, all participants performed similarly. Thus, frequency has a tendency show common time-based process participant, but processes exist between participants.
