Background:There is mounting evidence that regular physical activity is an important prerequisite for healthy cognitive ***,the finding that almost one-third of the adult population does not reach the recommended level of regular physical activity calls for further public health *** this context,digital and home-based physical training interventions might be a promising alternative to center-based intervention ***,this systematic review aimed to summarize the current state of the literature on the effects of digital and home-based physical training interventions on adult cognitive ***:In this pre-registered systematic review(PROsPERO;ID:CRD42022320031),5 electronic databases(PubMed,Web of science,Psyclnfo,sPORTDiscus,and Cochrane Library)were searched by 2 independent researchers(FH and PT)to identify eligible studies investigating the effects of digital and home-based physical training interventions on cognitive performance in *** systematic literature search yielded 8258 records(extra17 records from other sources),of which 27 controlled trials were considered *** reviewers(FH and PT)independently extracted data and assessed the risk of bias using a modified version of the Tool for the assEssment of study qualiTy and reporting in EXercise(TEsTEX scale).Results:Of the 27 reviewed studies,15 reported positive effects on cognitive and motor-cognitive outcomes(i.e.,performance improvements in measures of executive functions,working memory,and choice stepping reaction test),and a considerable heterogeneity concerning study-related,population-related,and intervention-related characteristics was noticed.A more detailed analysis suggests that,in particular,interventions using online classes and technology-based exercise devices(i.e.,step-based exergames)can improve cognitive performance in healthy older *** one-half of the reviewed studies were rated as having a high risk of bias with respect
