Abstract(s)
The 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.
