Research advances in physical activity and insomnia: a bibliometric and thematic evolution analysis.
Synthesis in Frontiers in psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Insomnia affects approximately 16.2% of the global population, constituting a substantial public health burden associated with diverse adverse health outcomes. Although physical activity (PA) represents a modifiable health behavior with demonstrated potential for sleep improvement, a systematic mapping of research hotspots and evolutionary trajectories in this domain remains lacking. Methods: We systematically retrieved English-language publications from the Web of Science Core Collection (WoSCC) from inception through May 20, 2026. A comprehensive search strategy combining subject headings with free-text keywords yielded 2,224 included records. We utilized the Bibliometrix package in R and VOSviewer software to visualize publication patterns across countries, institutions, journals, and authors; constructed thematic evolution maps; and identified research hotspots and emerging trends through strategic diagram analysis. We retrieved a supplementary Scopus dataset for cross-database validation. Web of Science served as the primary data source for analyses and visualizations, while Scopus verified trend consistency. Results: The annual growth rate of publications reached 15.12%. The United States (n = 397) and China (n = 462) emerged as the predominant contributing nations. High-impact institutions included Harvard University and the University of California system. Among journals, Sleep Medicine exhibited the highest h-index. Thematic evolution revealed four distinct phases: 2010-2018 focused on metabolic associations and measurement instruments; 2019-2021 shifted toward pandemic-related stress and sleep-emotion comorbidities; 2022-2023 established a "monitoring-intervention-evaluation" closed-loop paradigm; and 2024-2025 entered a "genetic causality-digital intervention" era. Mendelian randomization(MR) and wearable devices have emerged as cutting-edge frontiers. Cross-database validation with Scopus corroborated a high degree of concordance in publication trends and core thematic foci. Conclusion: The PA-insomnia research field has completed a paradigm shift from metabolic association validation to genetic causal precision, currently positioned at a critical juncture of multidisciplinary integration and digital transformation. Future research priorities might include, developing artificial intelligence-enabled wearable systems for real-time sleep-emotion-metabolism digital twin modeling, and advocating for the integration of multi-component "sleep hygiene plus exercise" interventions into clinical practice guidelines to address escalating sleep health challenges amid global population aging. Cross-database validation with Scopus corroborated a high degree of concordance in publication trends and core thematic foci.
