Abstract

This study compares polyrhythmic production ability between water polo players (WPs), artistic swimmers (ASs) and drummers (Ds), to assess how their differing experiences in coordinating complex inter-limb activity with music affected this ability. Eight ASs, eight WPs and eight Ds participated. They were asked to perform finger and foot taps in a single-rhythm task (every 750 ms) and two polyrhythmic tasks (finger and foot taps at 750 and 500 ms, respectively, and vice versa). The percentage of correct response cycles (PCRC), subjective difficulty scores were collected and analysed using a two-way mixed analysis of variance (ANOVA) and coefficients of variation of the inter-tap interval (CV_ITI) were collected and analysed using a three-way mixed analysis of variance (ANOVA). The three groups showed no statistically significant differences in the single-rhythm task. However, on polyrhythmic tasks, the WPs were significantly outperformed by the other two groups in PCRC and CV_ITI. These results suggest that the experience of coordinating limbs with music has positive impacts on polyrhythmic production ability. They also imply that ASs and Ds have similar polyrhythmic production ability despite the apparent differences in task complexity in their daily training and performances.

摘要

这项研究比较了水球运动员（WPs），艺术游泳者（ASs）和鼓手（Ds）之间的多节奏生产能力，以评估他们在协调复杂肢体活动与音乐方面的不同经历如何影响这种能力。八个AS，八个WP和八个D参加了会议。他们被要求在单节奏任务（每750毫秒）和两次多节奏任务（分别在750和500毫秒的手指和脚敲击，反之亦然）上执行手指和脚的敲击。收集并使用双向混合方差分析（ANOVA）和两次抽签间隔的变异系数（CV _ITI）收集并分析正确​​的反应周期（PCRC）的百分比，主观难度评分）并使用三方混合方差分析（ANOVA）进行分析。三组在单节律任务中无统计学差异。但是，在多节奏的任务中，PCRC和CV _ITI的WP明显优于其他两组。这些结果表明，使肢体与音乐协调的经验对多节奏生产能力具有积极影响。他们还暗示，尽管日常训练和表演的任务复杂性存在明显差异，但自治区和自治区具有类似的多节奏生产能力。
