The relationship between breathing laterality and motor coordination symmetry as a function of the symmetry of medial rotator muscle force in the shoulders was investigated. The principal objective was to distinguish swimmer profiles. Thirteen expert male swimmers performed the front crawl and were assessed for: (i) inter-arm coordination with the IdC and arm coordination symmetry with the Symmetry Index, (ii) breathing laterality, and (iii) the symmetry of the isokinetic force in the shoulder medial rotators. The results indicated that the relative duration of catch+pull was greater for the dominant arm (51.7%) than for the non-dominant arm (48.4%) for the swimmers with force asymmetry (p<0.05) and occurred on the side with the higher force (dominant arm). Two profiles were revealed: (i) swimmers for whom breathing laterality was related to force symmetry and stroke phase duration and (ii) swimmers for whom the impact of breathing laterality on force symmetry and stroke duration was low. The first profile corresponded to sprint specialists and the second profile corresponded more to middle-distance specialists.
研究了作为肩部内旋肌力量对称性函数的呼吸偏侧性与运动协调对称性之间的关系。主要目的是区分游泳运动员的类型。13名男性专业游泳运动员进行了自由泳，并接受了以下评估：(i) 使用IdC评估双臂间协调性以及使用对称指数评估手臂协调对称性，(ii) 呼吸偏侧性，以及(iii) 肩部内旋肌等速力量的对称性。结果表明，对于力量不对称的游泳运动员，优势臂的抓水+划水相对持续时间（51.7%）长于非优势臂（48.4%）（p<0.05），且发生在力量较大的一侧（优势臂）。揭示了两种类型：(i) 呼吸偏侧性与力量对称性及划水阶段持续时间相关的游泳运动员，以及(ii) 呼吸偏侧性对力量对称性和划水持续时间影响较小的游泳运动员。第一种类型对应短跑专家，第二种类型更对应中距离专家。
