Upon full formation, the movement structure is highly balanced and largely independent of the visual controls that is indicative of the movement control mechanism being dominated by the proprioceptive rather than visual controls.

driving the base spatial structure of the squat sequence. Furthermore, the study found the spatial and temporal structures of the joint angular movement sequence in the knee joint to be dominant for the squat i.e. However, the formation periods of the spatial and temporal structure of the joint angular movement sequence were different for different joints: in the knee joint it is formed by the age of 5-6 and in the ankle and hip joint in later age (1, 6, 7). In 67% of the tested groups, the structure was found formed by the age of 5 years, and in 86% by 6. The spatial and temporal structure of the joint angular movement sequence was found fully formed well before the powerlifting practices. It should be noted that the spatial and temporal structure of the joint angular movement sequence in the upward movement phase was found opposite to that in the downward movement phase and the higher was the motor skill the more expressed was this correlation. It was found that graphically the joint angular movement sequence may be represented as a parabolic curve with its left and right wings characteristic of the downward and upward phases (with the spatial and temporal structure) of the squat. The study data were used to profile the angular movement trajectories in the knee, ankle and hip joints, followed by the profiles being compared with thoseof adult powerlifters and 5-6 year-olds.

Subject to the tests were 60-80+ year-old people, with 60 squats captured by the Biosoft system followed by the video data processing by the VideoMotion_3D software toolkit.

The movement kinematics was registered by a 3D optical video-capturing system Biosoft. Studies of the squat kinematics in senior and declining-age people: 74 year-old LвЂ¦v. Subject to the tests was a sample of senior and declining-age people doing squats at comfortable pace: see Figure 1.ДЇigure 1. The study was performed at the Ergonomic Biomechanics Study Laboratory of Adyghe State University. Objective of the study was to identify and rate the regressive spatial and temporal changes in the joint angular movement structures in squat practices performed by senior and declining-age people. It should be emphasized that it is the natural locomotion control mechanisms that determine the opportunities for physical activation and progress in the senior and declining age.

Notwithstanding the progress of such studies and the common recognition of the active life prolongation effects of physical activity, the issues of aging-related regress of natural locomotion in different physical activities are still underexplored in the modern studies. Findings of such studies are mostly indicative of the physical activity being beneficial for active life prolongation with age. Premature aging prevention related issues and studies are in growing priority in modern medicine, biology, educational science and adaptive physiology.
