Abstract

It is known that changes in body weight affect postural balance in older women. Certain mobility limitations arise during common daily activities and changes take place indicating deterioration of the neurophysiological mechanisms responsible for maintaining vertical posture. Underweight and overweight older women show signs of adaptive rearrangements in the parameters of simple and complex walking. Our study aimed to develop factor models to determine postural indicators and the extent of their influence on the dynamic component of postural balance in women aged 60– 74 years with underweight, normal weight and overweight. The research involved 109 women, who were divided into 3 groups: underweight, normal weight, and overweight. Postural balance was evaluated using the Balance Manager system. The factor analysis of the dynamic component of postural balance showed that underweight and overweight older women, in contrast to those with normal body weight, demonstrate multidirectional shifts in factor distribution and structure. In overweight women, the most significant factor is the Step/Quick Turn test, which largely characterizes movement control, while in underweight women, the most significant factor is the Step Up/Over test, which most vividly describes the actual movement of the body
