Poor balance is responsible for a significant proportion of falls and injuries in older persons, and interventions to reduce falls and injuries are limited by our current understanding of balance. The proposed research plan will investigate the importance of ankle strength and ankle torque in the maintenance of balance function in older persons, specifically focusing on understanding postural responses to backward falls. The long range goal of the applicant is to develop kinetic models of dynamic balance. The applicant will perform two experiments to test the importance of ankle torque in dynamic balance. The first experiment is a cross-sectional study of persons over 75. In the second experiment, the applicant will work closely with Gail Dalsky, Ph.D., on an intervention study testing the effects of brisk walking and stair climbing on femoral bone density. The applicant will test if the exercise program will improve dynamic balance, and will measure the change in response kinetics which may explain the improvement.

差的差是造成很大比例的跌倒和 老年人的伤害以及减少跌倒和伤害的干预措施 受到我们当前对平衡的理解的限制。拟议的研究 计划将调查脚踝强度和踝关节扭矩的重要性 尤其是老年人的平衡功能的维护 专注于理解对向后跌倒的姿势反应。长 申请人的范围目标是开发动态动力学模型 平衡。 申请人将执行两个实验以测试踝关节的重要性 动态平衡中的扭矩。第一个实验是一项横断面研究 在75岁以上的人中。在第二个实验中，申请人将工作 与盖尔·达尔斯基（Gail Dalsky，Ph.D. 轻快步行和爬楼梯对股骨密度的影响。这 申请人将测试练习计划是否会提高动态平衡， 并将衡量反应动力学的变化，这可以解释 改进。
