Although physical activity (PA), sedentary behavior (SB), and sleep duration (SD) have been shown to be associated with MDD, the causal relationship is unclear. Methods: This study analyzed data from 22,474 participants in NHANES from 2007 to 2018. PA, SB, and SD were assessed by questionnaire, and MDD was defined by the PHQ-9 questionnaire. Associations were assessed using logistic regression modeling and controlling for demographic and health-related covariates. Also, two-sample Mendelian randomization (MR) analyses were performed using GWAS pooled data to explore potential causal relationships. Results: Low levels of PA (OR = 2.02, 95 % CI = 1.35–3.01, P < 0.001) and severe SB (OR = 1.54, 95 % CI = 1.03–2.31, P < 0.05) were associated with increased risk of MDD, while moderate PA (OR = 0.55, 95 % CI = 0.35–0.86, P < 0.01) and mild SB (OR = 0.65, 95 % CI = 0.43–0.97, P < 0.05) were protective. Recommended sleep duration (7–9 h) was associated with the lowest MDD risk (OR = 0.48, 95 % CI = 0.34–0.68, P < 0.001), whereas excessive sleep (>9 h) significantly increased the risk (OR = 3.40, 95 % CI = 1.93–5.99, P < 0.001). MR analysis showed a significant causal effect of aerobic exercise on reducing MDD risk (OR = 0.16, 95 % CI = 0.06–0.41, P = 0.0001), and no significant SB and SD were found causal relationship. Conclusions: Findings suggest that modifiable lifestyle behaviors significantly influence MDD risk, with aerobic exercise potentially having a causal protective effect. Improving mental health by promoting physical activity, reducing sedentary behaviors, and optimizing sleep duration is recommended.

This review provides a comprehensive methodological roadmap to overcome these barriers. METHODS: We conducted a structured literature search in PubMed, Web of Science, and Scopus for records published between 1998 and 2025 using predefined combinations of exercise and gut-microbiome terms. After deduplication, titles/abstracts and full texts were screened according to prespecified criteria, yielding 99 eligible studies on aerobic and resistance/anaerobic exercise and gut microbiota. Evidence is critically appraised across standard short-read 16S rRNA protocols, shotgun metagenomics, and emerging long-read sequencing, as well as metatranscriptomics, metabolomics, and associated bioinformatics pipelines. A PRISMA-style flow diagram summarizes the study-selection process. RESULTS: Exercise across diverse modalities reshapes gut microbial diversity and community structure, frequently enriching taxa such as Akkermansia muciniphila and Veillonella and enhancing production of short-chain fatty acids (SCFAs). SCFAs strengthen the intestinal barrier, activate anti-inflammatory pathways, and supply energy substrates for colonocytes and exercising muscle. Long-read sequencing now enables species-and strain-level resolution beyond short V-region amplicons, while inclusion of the gut mycobiome and virome expands ecological scope. Multi-omics designs integrating metagenomics, metatranscriptomics, and metabolomics connect microbial composition with functional outputs and host metabolic adaptations. CONCLUSIONS: The future of exercise–microbiome science lies not in enlarging static catalogs of responsive microorganisms but in constructing individual-level predictive models. Integrating long-read sequencing and multi-omics with standardized training metadata will enable precision exercise prescriptions and microbiome-targeted interventions, including tailored probiotics, synbiotics, and nutrition strategies. Adoption of these advanced methodologies can accelerate mechanistic insight and promote translation of exercise– microbiome research into athletic performance optimization and clinical practice. © 2025 Korean Society of Exercise Physiology.
