Background

Continuous relative phase (CRP) has gained popularity to assess movement performances in recent decades.

Research question

The application and interpretation of CRP in common movements such as running and jumping are still unclear.

Methods

This systematic review summarized the current applications, methodology, parameters of interest, and interpretations of CRP variables in running and jumping. Reviewed articles were found in five databases from January 1999 to December 2020, and 1613 records were obtained. After applying selection criteria and analysis of study quality to titles, abstracts, and full texts, 38 articles were identified for subsequent review.

Results

Twenty-eight reviewed articles relating to running were found to compare the coordination among pathological gait, footwear designs, running speed, gender, age, running level, fatigue state, and treadmill effect. In addition, ten reviewed articles relating to jumping were found to compare the coordination among different types of jump (e.g., squat jump coordination, countermovement jump, single leg jump) and insole effect.

Significance

The CRP and its variability (CRPv) are two common variables to describe the changes and differences of coordination patterns, respectively. These reviewed articles suggest that CRP tools are effective to assess the coordination and performances in running and jumping, as these values are related to external (environment/equipment) and internal (self-biological) changes. In the future, studying higher-order analysis of movement patterns using CRP tools can provide meaningful interpretation of movement behavior.

连续相对相位在跑跳研究中的应用现状：系统评价

背景

近几十年来，连续相对相位 (CRP) 在评估运动表现方面越来越受欢迎。

研究问题

CRP在跑、跳等常见动作中的应用和解释尚不清楚。

方法

这篇系统综述总结了当前的应用、方法、感兴趣的参数以及 CRP 变量在跑步和跳跃中的解释。1999 年 1 月至 2020 年 12 月在 5 个数据库中检索到评论文章，获得 1613 条记录。在对标题、摘要和全文应用选择标准和研究质量分析后，确定了 38 篇文章供后续审查。

结果

发现 28 篇与跑步有关的评论文章，比较了病理步态、鞋类设计、跑步速度、性别、年龄、跑步水平、疲劳状态和跑步机效果之间的协调性。此外，还发现了 10 篇与跳跃相关的评论文章，比较了不同类型跳跃之间的协调性（例如，蹲跳协调性、反向运动跳跃、单腿跳跃）和鞋垫效果。

意义

CRP及其变异性（CRPv）是两个共同的变量，分别描述了协调模式的变化和差异。这些评论文章表明，CRP 工具可有效评估跑步和跳跃的协调性和表现，因为这些值与外部（环境/设备）和内部（自身生物）变化有关。未来，使用 CRP 工具研究运动模式的高阶分析可以提供对运动行为的有意义的解释。
