TEIXEIRA, Genoveva et al. Angular kinematics of head-out-aquatic exercise “Sailor Jigs” at increasing musical rhythm. Motri. [online]. 2015, vol.11, n.2, pp.143-152. ISSN 1646-107X.  https://doi.org/10.6063/motricidade.3978.

The aim of this study was to analyze the relationships between the angular kinematic pattern of head-out aquatic exercise sailor jigs” at increasing musical rhythm. Six young women with at least one year of experience conducting this type of head-out aquatic programs were evaluated. The exercise was recorded on video, in frontal plane, using two cameras for double projection at five music cadences (120 bpm, 135 bpm, 150 bpm, 165 bpm and 180 bpm). Images were then digitized in specific software (Ariel Performance Analysis Systems). Results have shown that, the cycle period decreased through the incremental protocol. No significant relationship was found between music rhythm and relative angle between thigh and trunk. In contrast, the relative angle between thigh and leg and between arm and forearm decrease with the music rhythm, at least for the left limb. In conclusion, it seems that there is a trend to decrease the angular displacement and unchanged the angular velocity when increasing rhythm at least in certain anatomical landmarks.
