تاثیر تمرینات ایروبیک، ایروبیک در آب و تمرین در آب بر حافظه کاری زنان سالمند مبتلا به آلزایمر

Introduction and purpose: Physical inactivity is an important risk factor for cognitive decline in ageing and for Alzheimer&rsquo;s disease. The aim of this study was to investigate The effect of Aerobic in water and Exercises in water on working memory in elderly women with Alzheimer's disease. Material and Methods: This study was a quasi-experimental study. The statistical community consisted of 30 elderly women with the mean age of 64.6&plusmn;2.9 that were randomly assigned into three groups (10 per groups) water exercise, aerobic & aerobic in water. The training protocol was 18 sessions (6 weeks), and each session 45 minutes. In order to measure memory was used The Wechsler Memory Scale (WMS) and to measure working memory was used the N-Back software. Data were analyzed by ANOVA repeated measures (2&times;3) by spss-22 software. Results: the results show that after the exercise program participant in aerobic in water (P=0.003) and exercise in water (P=0.007) had a significant improvement in working memory (P<0.05). But aerobic group in this period of time hadn't significant improvement (P=0.103). Eta square showed that the aerobic in water (Eta=0.649) was more effective from exercise in water (Eta=0.574) in working memory. Conclusion: Although the research background shows that in general aerobic exercises can improve the cognitive function of elderly patients with Alzheimer's disease, it was found in this research that aerobic exercises in water and even exercise in water is better and faster than aerobic exercises to improve working memory in elderly women with Alzheimer's. Therefore, it is suggested for all people who are affiliated with Alzheimer's elderly to use water practice protocols to improve cognitive processes.
