The emergence of physical adaptations through the confinement of the environment and homework has been widely used as a training method in the study of sports performance. Task and environment constraints are very important in cognitive, perceptual, decision-making, and tactical behaviors. Therefore, the present study intends to investigate the effect of task restraint manipulation on kinetic indicators and excellence associated with the risk of falling in the elderly. For this purpose, 45 elderly people were randomly divided into three groups according to the inclusion and exclusion criteria of the study: homework restraint manipulation, non-homework restraint manipulation and control group. The experimental groups then performed homework restraint exercises and non-restraint exercises for eight weeks. The control group also continued their normal activities during the investigation. Static balance meter was used to evaluate the kinetic index and leaf test was used to evaluate the dynamic balance. The results of analysis of covariance by removing the effect of pretest showed that the group obtained significantly higher scores than the group without manipulation and control by manipulating the task constraints in the kinetic index and Burke scale with (P = 0.000) high reliability. The results of this study supported the use of various manipulations of homework constraints as a kind of teaching strategy for the elderly. It also confirms the effect of exercises by manipulating the restrictions of the task, which improves balance in the elderly, and by improving this ability, the risk of falling in this segment of society is reduced.
