The Mediating Effect Of Physical Fitness Between Depression And Fall Risk In Regional Elderly

In order to reduce the fall risk of elderly,we try to clarify the role of physical fitness in depression and fall risk,furthermore this study assess the rate of three variables of physical fitness based on individual subjects.The subjects were 833 aged people in Shenyang,the study used the method of questionnaire investigation,measurement and mathematical statistics.The knowledge of related disciplines was used to analysis and explain the relationship of depression,exercise capacity(balance quality,speed quality and sensitive quality)and fall risk.and further analysis of the impact of depression next,the individual exercise capacity three evaluation indicators of the interactive relationship between the risk of falling,summarizes the trend and related emotions,exercise ability of depression among the elderly in Shenyang city and the basic characteristics of the risk of falling.Research shows:1.The degree of depression of elderly in Shenyang is in the normal range,and the median score was 8 points;the male standing protrusive averaged 30.43 cm,timed up and go for an average of 9.31 seconds,10 meters maximum walking speed is 1.73 seconds on average,women stand in the forward extension average is 30.28 cm,timed up and go for an average of 9.35 seconds.10 meters maximum walking speed of 1.70 seconds on average;and the risk of falling median score was 2 points,most people is in low risk of falls.2.Structure model of path coefficients,there is a significant correlation between depression mood,fall risk and exercise ability the elderly in Shenyang,furthermore verify the fall risk and the movement ability and depression was negatively related to depression,tend to fall risk was positively correlated;fitting indicators showed that the model has better adaptability,the movement ability of intermediary effect on the relationship between depression and the risk of falling in.There was no significant difference between the model and the gender as a variable,indicating that sex had no significant influence on the result.3.According to the triangular coordinate graph,it is found that the elderly with the lower ratio of 10 meters and the higher ratio of standing walk time are higher than those of other elderly people.Combined with the mediating effect analysis model and the trigonometric coordinate map,it is clearly that the emergence of depression can lead to the overall decline of athletic ability.When the ability of 10-meter maximum walking and the standing time is declined,the elderly with depression will have higher risk of falling.Therefore,when formulating precise exercise prescription,we should focus on improving walking quality and sensitive quality,improving the quality of life of the elderly and achieving the goal of healthy aging.
