Abstract

Consequences of falls in older adults are a serious issue and challenge for healthcare systems. Many of the falls result in serious injuries, including bone fractures, which necessitate long hospital stays; and their consequences often have unfavourable effect on the level of functional independence of older adults. Balance disorders and resulting falls are related to the natural processes of ageing, including weakened muscle strength and gradual decrease of function of all the systems of the body. It seems that a properly planned and conducted intervention programme may be an important factor in preventing falls in this age group. Therefore, the aim of this study was to assess changes in balance and falls risk index in women aged over 50 years following two different types of training. The study involved 36 physically active females (mean age 67.11±5.35). Within the intervention, the studied women participated in a programme of whole-body training (8 weeks) and strength training (8 weeks). Balance assessment, including falls risk index, to determine the changes induced by the training was performed four times (before and after both training programmes) with the use of the Balance System SD platform by Biodex. We observed a significant improvement of balance, particularly in trials with eyes open, for both types of training and for the whole period of intervention. The risk of falls index decreased significantly, too. We found that the different type of exercise in regard to movement structure and to the type of impact influenced individual balance indices (overall stability index, anterior/posterior stability index, medial/lateral stability index) in slightly different ways. This may be a premise for designing intervention programmes targeted at falls prevention in older adults. Moreover, it turned out that the balance levels can be trained even in physically active subjects.
全身和力量训练对50岁以上体力活动妇女平衡和跌倒风险的影响
老年人跌倒的后果是卫生保健系统面临的一个严重问题和挑战。许多摔伤造成严重伤害,包括骨折,需要长期住院;其后果往往对老年人的功能独立水平产生不利影响。平衡失调和由此导致的跌倒与衰老的自然过程有关,包括肌肉力量减弱和身体所有系统功能的逐渐下降。看来,适当计划和实施的干预方案可能是预防这一年龄组跌倒的重要因素。因此,本研究的目的是评估50岁以上女性在两种不同类型的训练后平衡感和跌倒风险指数的变化。研究对象为36名身体活跃的女性(平均年龄67.11±5.35岁)。在干预期间,研究女性参加了全身训练(8周)和力量训练(8周)。使用Biodex的Balance System SD平台进行了四次平衡评估,包括跌倒风险指数,以确定训练引起的变化(在训练计划之前和之后)。我们观察到平衡性的显著改善,特别是在睁着眼睛的试验中,对于两种类型的训练和整个干预期间。跌倒风险指数也显著下降。我们发现,不同类型的运动对运动结构和冲击类型对个人平衡指数(整体稳定性指数、前后稳定性指数、内侧/外侧稳定性指数)的影响略有不同。这可能是设计针对老年人预防跌倒的干预方案的前提。此外,事实证明,即使是在体育活动中,平衡水平也可以得到训练。
