Moreover, there is evidence for a link between the autonomic deficit measurable by reduced HRV and the hypoactivity of the cholinergic system, which is prominently affected in Alzheimer's disease (AD). Despite the positive influence of physical exercise on cognition and its promising association with HRV, previous studies did not explore the effect of long-term physical exercise in older adults with AD. Taking advantage of a longitudinal study we analyzed the effect of a 20-week dual task training regime (3 × 15-min per week) on the vagal mediated HRV index RMSSD (root mean square of successive RR interval differences) during physical exercise and the short-term memory performance in a AD cohort (N = 14). Each training contained physical exercise on a bicycle ergometer while memorizing 30 successively presented pictures as well as the associated post-exercise picture recognition memory test. Linear-mixed modeling revealed that HRV-RMSSD significantly increased over the intervention time. Moreover, the reaction time in the picture recognition task decreased while the accuracy remained stable. Furthermore, a significantly negative relationship between increased fitness measured by HRV-RMSSD and decreased reaction time was observed. This feasibility study points to the positive effects of a dual task regime on physical and cognitive fitness in a sample with impaired cognitive performance. Beyond this, the results show that the responsiveness of parasympathetic system as measured with HRV can be improved in patients with dementia. 000164211 536__ $$0G:(DE-HGF)POF4-353$$a353 - Clinical and Health Care Research (POF4-353)$$cPOF4-353$$fPOF IV$$x0 000164211 588__ $$aDataset connected to CrossRef, Journals: pub.dzne.de 000164211 7001_ $$0P:(DE-2719)9002229$$aBusse, Nancy$$b1$$udzne 000164211 7001_ $$0P:(DE-2719)2814076$$aZiegler, Gabriel$$b2 000164211 7001_ $$0P:(DE-2719)2811614$$aGlanz, Wenzel$$b3 000164211 7001_ $$0P:(DE-2719)2811221$$aBecke, Andreas$$b4 000164211 7001_ $$0P:(DE-2719)2000005$$aDüzel, Emrah$$b5$$eLast author 000164211 773__ $$0PERI:(DE-600)2969725-6$$a10.3389/fspor.2021.684089$$gVol. 3, p. 684089$$p684089$$tFrontiers in sports and active living$$v3$$x2624-9367$$y2021 000164211 8564_ $$uhttps://pub.dzne.de/record/164211/files/DZNE-2022-00867.pdf$$yOpenAccess 000164211 8564_ $$uhttps://pub.dzne.de/record/164211/files/DZNE-2022-00867.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000164211 909CO $$ooai:pub.dzne.de:164211$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)9000379$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b0$$kDZNE 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)9002229$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b1$$kDZNE 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2814076$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b2$$kDZNE 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2811614$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b3$$kDZNE 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2811221$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b4$$kDZNE 000164211 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2000005$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b5$$kDZNE 000164211 9131_ $$0G:(DE-HGF)POF4-353$$1G:(DE-HGF)POF4-350$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lNeurodegenerative Diseases$$vClinical and Health Care Research$$x0 000164211 9141_ $$y2021 000164211 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ$$d2020-08-26 000164211 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000164211 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2020-08-26 000164211 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2020-08-26 000164211 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2022-11-08 000164211 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2022-11-08 000164211 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2021-05-12T13:26:50Z 000164211 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2021-05-12T13:26:50Z 000164211 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review$$d2021-05-12T13:26:50Z 000164211 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2022-11-08 000164211 915__ $$0StatID:(DE-HGF)0112$$2StatID$$aWoS$$bEmerging Sources Citation Index$$d2022-11-08 000164211 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2022-11-08 000164211 9201_ $$0I:(DE-2719)1310003$$kAG Müller$$lNeuroprotection$$x0 000164211 9201_ $$0I:(DE-2719)5000006$$kAG Düzel$$lClinical Neurophysiology and Memory$$x1 000164211 9201_ $$0I:(DE-2719)1340013$$kKAP$$lCooperation Unit for Applied Prevention Research (KAP)$$x2 000164211 980__ $$ajournal 000164211 980__ $$aVDB 000164211 980__ $$aI:(DE-2719)1310003 000164211 980__ $$aI:(DE-2719)5000006 000164211 980__ $$aI:(DE-2719)1340013 000164211 980__ $$aUNRESTRICTED 000164211 9801_ $$aFullTexts
