Abstract

We investigated the molecular mechanisms of exercise adaptations in human muscle by integrating genome, methylome, transcriptome, and proteome data from over 1,000 participants (2,340 muscle samples). We identified distinctive signatures associated with maximal oxygen consumption (VO 2max ), and multi-omics integration uncovered five key genes as robust exercise markers across layers, with transcription factors functioning as activators, synergizing with DNA methylation to regulate gene expression. Minimal sex differences were observed, while modality-specific analysis highlighted distinct pathways for aerobic and resistance exercise, contrasting with muscle disuse patterns. Finally, we created a webtool, OMAx, featuring our individual omics and integration analysis. These findings provide a comprehensive multi-omics framework for understanding exercise-induced molecular adaptations, offering insights into muscle health, cardiorespiratory fitness, and their roles in aging and disease prevention.

  • While acute exercise initiates immediate metabolic adjustments, chronic activity reinforces and expands these effects, driving lasting improvements in muscle oxidative capacity and energy homeostasis.

    “Therefore, while acute exercise initiates immediate metabolic adjustments, chronic activity reinforces and expands these effects, driving lasting improvements in muscle oxidative capacity and energy homeostasis [34].”

    From Exercise-Induced Muscle–Fat Crosstalk: Molecular Mediators and Their Pharmacological Modulation for the Maintenance of Metabolic Flexibility in Aging (2025) · cites this paper as [34]

    The Discussion (page not specified in our copy) says exercise-related DNA methylation changes recur after each bout and may stabilize with training, potentially contributing to long-term muscle adaptation. It also links exercise-associated molecular pathways to mitochondrial metabolism and energy homeostasis, but does not establish that chronic activity drives lasting improvements in oxidative capacity or energy homeostasis.

  • Multi-omics analyses and human cohort studies show that trained individuals, regardless of age, presented increased levels of mitochondrial markers and more efficient myokine responses following exercise.

    “Multi-omics analyses and human cohort studies further show that trained individuals, regardless of age, presented increased levels of mitochondrial markers and more efficient myokine responses following exercise.”

    From Exercise-Induced Muscle–Fat Crosstalk: Molecular Mediators and Their Pharmacological Modulation for the Maintenance of Metabolic Flexibility in Aging (2025) · cites this paper as [34]

    The proteome results (page unavailable) link higher VO₂max with higher expression of some proteins and enrichment of mitochondrial-function pathways; the multi-omics results also report greater abundance of mitochondrial-pathway mRNA and proteins. These findings partly support the mitochondrial-marker claim, but the paper does not establish that this holds regardless of age or report more efficient myokine responses in trained individuals after exercise.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
