Objective adherence was defined as compliance with the prescribed exercise volume and quantified using cumulative metabolic equivalent minutes (MET-mins) derived from heart rate data reflecting session intensity and duration across the programme, as opposed to behavioural self-report measures.

Controlled motivation was similar between groups. Profiles did not differ in demographic or physiological characteristics at baseline. Adherence was high and comparable across the two profiles for all indices (e.g., cumulative MET-mins: 129 ± 66% vs. 116 ± 38%).

The programme incorporated consistent objective monitoring of exercise behaviour, along with regular guidance and feedback from the research team delivered through scheduled participant contact. This level of structured behavioural support may have reduced the influence of psychological profile membership on exercise adherence and fitness outcomes, resulting in comparable positive outcomes across participants.

In recent years, physical exercise interventions have attracted considerable attention as a potential approach to modify cognitive decline, which is a major shared symptom of these disorders. In this systematic review and meta-analysis, we focused on studies investigating the effectiveness of physical exercise interventions for various cognitive domains in patients with Alzheimer’s disease (AD), Parkinson’s disease (PD) or mild cognitive impairment (MCI), who presented with initial cognitive deficits. METHODS: We performed a systematic literature search in PubMed, Embase and CENTRAL for randomized controlled trials (RCTs) published in English until October 2025. We considered them eligible when they investigated the effects of physical exercise on cognitive functioning in AD, PD or MCI patients who all already had cognitive deficits before the start of the study. A random-effects model was applied to explore the effects of physical exercise on four main cognitive domains: global cognition, executive function, memory and attention. RESULTS: In total, 28 RCTs were eligible for inclusion in this review (AD n = 8; MCI n = 16; PD n = 4). Patient subgroup analyses revealed that physical exercise significantly improved global cognition, executive function, memory and attention in both the MCI and AD patient groups, whereas no significant effects were observed in PD patients. CONCLUSIONS: These findings indicate that exercise-related benefits extend across multiple cognitive domains in AD and MCI patients and support its potential as a non-pharmacological strategy for individuals with neurodegenerative disorders. In PD, evidence remains limited and inconclusive. Despite substantial variability in exercise interventions, consistent effects were observed, suggesting that cognitive benefits may be broadly applicable across different modalities. However, the limited number of studies including patients with objectively verified cognitive impairment, particularly in PD, as well as the focus on global cognition in many AD studies, highlight important gaps in the current literature. Future research should specifically target cognitively impaired populations and include sufficiently large and well-characterized samples to improve the precision and clinical applicability of the evidence. </p>","PeriodicalId":50477,"journal":{"name":"European Review of Aging and Physical Activity","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13274241/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147787993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing literature has predominately examined total PA volume or sedentary time in relation to cognitive health, with limited attention to the distributional features of the movement activity bouts. Variability in the duration of daily movement activity bouts may influence cognitive function beyond total exposure to PA or sedentary time. This study investigates whether daily PA and sedentary bout distributions are associated with daily cognitive function in older adults, and further explores whether these associations differ across the days of the week. METHODS: Older adults (n = 87, age = 68.5 ± 7.0 years, 38% male, 21% non-White) with elevated dementia risk completed 14 days of ecological momentary assessment (EMA). Participants wore an accelerometer (activPAL) and completed smartphone-based cognitive assessments of processing speed four times each day. The number and duration of sedentary, light (LPA), or moderate-to-vigorous physical activity (MVPA) bouts (≥ 1 min) were calculated from the activPAL data. Median response time (RT) and number of correct trials from the symbol search task were aggregated at the day level. Two distributional indicators (alpha and Gini) were each calculated for daily sedentary, LPA, and MVPA bouts to investigate their associations with the symbol search outcomes. Functional regression models examined the associations between the distributional indicators and cognitive outcomes by each day of the week (Sunday-Saturday). RESULTS: On most weekdays, higher Gini (greater variations) in daily MVPA bout length was associated with faster RT (p<.001, R2=0.138); higher Gini of daily LPA bout length was also associated with more accurate trials (p<.05, R2=0.022). Conversely, higher Gini in daily sedentary bout length was associated with slower RT (p<.05, R2=0.164). CONCLUSIONS: This study provides proof-of-concept that the distribution of daily movement behavior bouts is associated with variations in daily cognition. It also illustrates how integrating accelerometry with repeated ambulatory cognitive measures can capture within-person dynamics. The findings can support future research to examine whether specific daily movement patterns may represent appropriate targets for interventions aimed at promoting cognitive health in older adults. </p>","PeriodicalId":50477,"journal":{"name":"European Review of Aging and Physical Activity","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13227851/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147730595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
