CONCLUSION On the basis of systematic review of relevant literature , it appears that muscle fatigue induces clear deteriorations in reactive postural control .
BACKGROUND Falls are the leading cause of traumatic brain injury and fractures and the No. 1 cause of emergency department visits by older adults .
Although declines in muscle strength and sensory function contribute to increased falls in older adults , skeletal muscle fatigue is often overlooked as an additional contributor to fall risk .
In an effort to increase awareness of the detrimental effects of skeletal muscle fatigue on postural control , we sought to systematic ally review research studies examining this issue .
PURPOSE The specific purpose of this review was to provide a detailed assessment of how anticipatory and reactive postural control tasks are influenced by  acute muscle fatigue in healthy older individuals .
Effectiveness of aquatic and non-aquatic lower limb muscle endurance training in the static and dynamic balance of elderly people.
BACKGROUND Aging compromises the ability of the central nervous system to maintain body balance and reduces the capacity for adaptive reactions . To prevent falls , the reception conditions for sensory information need to be improved . OBJECTIVES To evaluate the impact of a structured aquatic and a non-aquatic exercise program for lower-limb muscle endurance on the static and dynamic balance of elderly people . METHODS This was a prospect i ve r and omized clinical study in which the variables were assessed before and after the training program . Thirty-six elderly people were evaluated using four tests : the Berg Balance Scale , Dynamic Gait Index , gait speed and t and em gait . The participants were r and omized into three groups : aquatic exercise group , non-aquatic exercise group and control group . The exercise groups underwent a program for lower-limb muscle endurance that consisted of 40-minute sessions twice a week for six weeks . The participants were reevaluated after six weeks . The data were analyzed statistically using the univariate ANOVA test for comparisons between the groups before and after the intervention . RESULTS The program for lower-limb muscle endurance significantly increased balance ( p<0.05 ) in the evaluation tests after the training program . CONCLUSION The muscle endurance program provided a significant improvement in static and dynamic balance among community-dwelling elderly people . It was also possible to infer that this improvement occurred regardless of the environment , i.e. aquatic or non-aquatic .
