Spontaneous activity of lower limbs in a vertical position in the aquatic environment

Title: Spontaneous activity of lower limbs in a vertical position in the aquatic environment Objectives: The aim of this study was to determinate whether spontaneous activity of lower limb in the aquatic environment enable to determinate preferred swimming stroke of an individual. Also, whether identified asymmetry of the lower limbs during treading water depend on passive range of hip joints. Methods: Spontaneous activity of lower limbs in a vertical position with a hands and head out of water was recorded on video. Passive intra/extrarotion, flexion, extension, abduction in hip joints were measured using mechanical two-arm goniometer. Qualitative analysis of spontaneous activity of lower limbs recorded on video was conducted using Kinovea 0.8.15. Results: According to the results of our work, it can not be said that the preferred swimming stroke can be determined on the basis of the spontaneous activity of the lower limbs in a vertical position in the aquatic environment. We can assume that the individual chose the pattern of treading water according to an energetically economical way while minimizing resistive forces and not in pursuance of preferred swimming stroke. Bilateral asymmetry (left-right) during the water treading movement was detected in the whole group. The most significant..
