The goal of this interventional study is to compare in community dwelling elderly people the effects of two physical activity programs to prevent accident falls : "SILVER XIII EQUILIBRE" program and "VIVIFRAIL" program, on several risks factors such as executive functions and functional capacities.
Participants will perform a 1 hour physical activity session during 10 weeks and effects will be measured using a multidimensional test battery. "SILVER XIII EQUILIBRE" program contains cognitive-motor exercises where participants have to perform two tasks simultaneously such as answering math questions while walking whereas "VIVIFRAIL" program contains multifactorial exercises such as walking, balance training and resistance training in single-task condition.
The main question it aims to answer is :
Falls in the elderly are a problem of increasing importance in our aging societies. Among the multiple intrinsic risk factors, if the age-induced decline of functional and locomotor capacities are recognized risk factors, impaired executive functioning is another equally important one. Thus, Mild Cognitive Impairment (MCI) - characterized by an early deficit in executive functioning but not pathological - turns out to be an independent and significant risk factor. In order to reduce the impact of this problem and thus promote "well aging", it is essential to develop effective preventive approaches on all of these risk factors. Of these, cognitive-motor fall prevention programs - based on simultaneous cognitive and motor tasks - are the most effective in reducing the rate of falls. However, since 2017, the French Rugby League Federation has been proposing such an innovative program called "SILVER XIII - EQUILIBRE" consisting of 10 one-hour sessions per week and including a majority of cognitive-motor exercises. In addition, this program also includes exercises for learning the "play the ball", a specific skill of rugby league that consist of shooting the ball with the heel and making a step forward which is close to the stepping strategy to avoid falling. Initially intended for community dwelling elderly people and non-fallers presenting a usual aging (average age = 67.6 +/- 3 years), it turns out that this program welcomes three different profiles of elderly people that we find in the literature: (1) young-aged, active people with no deficits in functional and cognitive abilities; (2) older people with optimal cognitive aging but less active (3) older people with MCI. As the effects of regular Physical Activity (PA) depend on the initial level of each individual, it could be that the effects of the "SILVER XIII - EQUILIBRE" program on both functional abilities and executive functions depend on the profile of the elderly. In order to answer the main question the effects of the "SILVER XIII EQUILIBRE" program will be compared to an active comparator : the "VIVIFRAIL" program which is a international multifactorial program to prevent falls based on walking, balance and resistance training single task exercises.
