Empirical evidence shows that the elderly perceive distances as farther compared with younger adults and that the harder the ground surface to walk, the farther the perceived distance. Such results suggest a general perceptual readaptation promoted by the aging process that is fine-tuned with the decline of the motor resources. However, it is still unknown whether the elderly space perception is affected by interindividual differences in their functional autonomy (FA) and whether the decline of motor resources affects spatial categorization only when distances are judged with reference to the observer's own body or also when they are judged with reference to the body of another agent present in the scene. To this aim, a sample of elderly adults with preserved cognitive functions but different levels of FA, measured through the Instrumental Activity of Daily Living (IADL) scale, were enrolled and tested on the extrapersonal space categorization task. This task requires judging the position of a target as \"Near\" or \"Far\" with respect to different reference frames (RFs): centered on the observer's body (Self RF) or centered on external elements, like another body (Other RF) or an object (Object RF). Results indicated that the higher the level of FA, the wider the space categorized as \"Near\" when adopting as reference frame our own body or the body of another agent in the scene, but not a static object. In conclusion, the individual functional autonomy of elderly individuals, which is strongly influenced by motor resources and efficiency, modulates how the surrounding space is represented, but only when the distance judgment implies an agent body, thus providing new relevant data for recent embodied cognition models of aging.</p>","PeriodicalId":14933,"journal":{"name":"Journal of Aging Research","volume":"2020 ","pages":"5694790"},"PeriodicalIF":4.7,"publicationDate":"2020-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2020/5694790","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37717470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another relevant factor in aging is chronic subliminal inflammation, with increased levels of circulating inflammatory cytokines such as interleukin-6 (IL-6), tumor necrosis factor <i>α</i> (TNF-<i>α</i>), and soluble tumor necrosis factor receptor 1 (sTNFR-1), commonly seen in the elderly. High levels of these inflammatory mediators could impair the functional capacity. In this respect, the aim of this cross-sectional study was to compare plasma levels of inflammatory mediators and functional capacity of older women living in three Brazilian counties with different Human Development Index. We evaluated 154 women aged ≥65 years, regardless of race and/or social status. IL-6 and sTNFR-1 plasma levels were measured by ELISA and the functional capacity by the Short Physical Performance Battery (SPPB) test. Comparison among groups was performed using one-way ANOVA with Bonferroni post hoc correction, Kruskal-Wallis, and Mann-Whitney <i>U</i> tests. Women that lived in one of the counties with high HDI had lower functional capacity (<i>p</i> < 0.001). The population from the county with the highest HDI had lower plasma levels of sTNFR-1 (<i>p</i> < 0.05). There was no significant difference in plasma levels of IL-6 (<i>p</i> > 0.05). Besides this, women from the counties with lower HDI had a higher number of self-reported diseases and higher income (<i>p</i> < 0.05). Women that lived in the county with the highest HDI had a higher average education level (<i>p</i> < 0.05). The results showed differences in functional capacity and plasma levels of sTNFR-1 between the counties.

The march was taking place 3 times a week for 30-40 minutes over a period of 8 weeks. In the time of training, the subjects did not practise any other physical activity for 8 weeks. The measurement of skin microcirculation was done by using the laser Doppler flowmeter estimating the values of regular flow and the reactions provoked in response to occlusion and temperature.

Community-dwelling older adults (20 males and 27 females) aged 65-87 years (<i>M</i> = 71.8 years, SD = 6.04 years) were randomized into supplement (<i>N</i> = 33) and placebo groups (<i>N</i> = 14) using simple randomization.
