(2020). Inter-limb symmetry at simultaneous and alternated arms flexion by the elbow during water fitness sessions. Symmetry. ISSN 2073-8994. 12:11, p. 1-72073-8994http://hdl.handle.net/10198/23023The aim was to compare the inter-limb symmetry between alternated and simultaneous arms flexion during water fitness sessions. Twenty-three elderly women were recruited to perform flexion by the elbow with di erent mechanical strategies: (a) simultaneous and (b) alternated. An incremental protocol was used, with four music cadences, starting at 105 beats per minute up to 150. The peak force of dominant and non-dominant upper-limbs was retrieved. A symmetry index (SI, %) was also used to quantify coordination. There were significant variations in force produced by the dominant and non-dominant limbs in most of the cadences in the alternated or simultaneous actions. Differences with a medium e ect between upper-limbs were shown when moving simultaneously indicating that an alternated movement can be a more proper strategy to work with. Despite that, both strategies seemed to be characterized by an asymmetric pattern (SI from 20 to 30%), requiring full attention from water fitness practitioners.engWater-based exerciseSegmental actionCoordinationAsymmetriesOlder adultsjournal article10.3390/sym12111776
