Movement activity and body stability as a part of life style in different life periods

Introduction. Physical activity is an important factor both composing human ability and influencing health status. Unspecific physical activity, especially in earlier life periods, generates a kind of potential, which can influence functioning of the elderly. Physical fitness, giving not only independence in some extend, but also abilities of coping with unpredicted situations, requiring involvement of coordination, skills, especially balance skills, are recognized as essential in such an age group It is presently one of leading research directions, conducted with priority of fall prevention among the elderly. Nonetheless, the question of posture and balance control applies to individuals of every age. An objective control of balance skills (body stability) seems important, as recognizing any deficits in this respect can be a valuable indication towards establishing specific preventive actions, soothing such deficits or minimizing consequences of a potential fall. The aim of the study was to define the influence of level of previous physical activity on body stability in aged individuals. Material and methods. Over 100 volunteers, aged 20 – 70 years, with some outnumber of females, took part in the study. Data about intensity and characteristics of present and past physical activity was taken from participants. Balance and body stability were measured with AMTI stabilographic platform. Balance regulation skills and stability (stability safety margin) were assessed. The stabilographic data, with subjects’ age and physical activity, were analyzed statistically. Results. The findings indicate interpersonal heterogeneity of body stability regulation ability, stability and reaction time. A tendency towards worse results was seen in subjects over 50 years of age, as compared to younger participants, especially in stability, manifested by increased [so called] safety margin, especially during backward swings. A tendency towards better results was observed in subjects formerly more physically active, regardless the age. The correlation was not thoroughly consistent, however Conclusions. Interpersonal heterogeneity of body stability and tendency for its declining with aging indicate that risk of falls among aged people does appear, but varies interpersonally. Better results, normally achieved by more active persons, suggest it purposeful to treat physical activity as a longdistance prophylaxis. Physical activities engaging coordination and balance control to a greater extend seem more beneficial in this respect.
