The age-related changes for controlling grip force in adults who practice regular and supervised physical activity have not been investigated. Fifty-five physically active adults ages 50 years and older and a group of 20 young adults (18-30 years old) performed a task of grasping and lifting an object. The grip force and the object's acceleration were recorded and used to calculate the parameters of grip force control. The levels of daily physical activities were also examined in all age groups. There were no differences in grip force control between the age groups. Conversely, the group over 76 years old used stronger grip force and increased latency (the time from grip force application to the time the object is lifted off the table) to manipulate the object. The results of this study suggest that middle-aged and older adults who exercise regularly can reduce or delay the possible grip force control deficits associated with aging.
针对有规律且受监督进行体育活动的成年人，与控制握力相关的年龄变化尚未得到研究。五十五名年龄在50岁及以上的体育活动参与者和一组20名年轻人（18 - 30岁）进行了一项抓取和举起物体的任务。记录握力和物体加速度，并用于计算握力控制参数。所有年龄组的日常体育活动水平也进行了检查。各年龄组之间在握力控制方面没有差异。相反，76岁以上的组使用更强的握力，并增加了延迟（从施加握力到物体从桌子上被举起的时间）来操作物体。这项研究的结果表明，经常锻炼的中老年人可以减少或延迟与衰老相关的可能的握力控制缺陷。
