Abstract

In the present bed rest (BR) study, 23 volunteers were randomized into 3 subgroups: 60 d BR control (Ctr); BR with resistive exercise (RE; lower‐limb load); and resistive vibration exercise (RVE; RE with superimposed vibration). The aim was to analyze by confocal and electron microscopy the effects of vibration on myofibril and filament integrity in soleus (Sol) and vastus lateralis (VL) muscle; differential proteomics of contractile, cytoskeletal, and costameric proteins (TN‐C, ROCK1, and FAK); and expression of PGC1a and atrophy‐related master genes MuRF1 and MuRF2. RVE (but not RE) preserved myofiber size and phenotype in Sol and VL by overexpressing MYBPC1 (42%, P ≤0.01), WDR1 (39%, P ≤0.01), sarcosin (84%, P ≤0.01), and CKM (20%, P ≤0.01) and prevented myofibrillar ultrastructural damage as detectable by MuRF1 expression. In Sol, cytoskeletal and contractile proteins were normalized by RVE, and TN‐C increased (59%, P ≤0.01); the latter also with RE (108%, P ≤0.01). In VL, the outcomes of both RVE (acting on sarcosin and desmin) and RE (by way of troponinT‐slow and MYL2) were similar. RVE appears to be a highly efficient countermeasure protocol against muscle atrophy and ultra‐structural and molecular dysregulation induced by chronic disuse.—Salanova, M., Gelfi, C., Moriggi, M., Vasso, M., Viganò, A., Minafra, L., Bonifacio, G., Schiffl, G., Gutsmann, M., Felsenberg, D., Cerretelli, P., Blottner, D., Disuse deterioration of human skeletal muscle challenged by resistive exercise superimposed with vibration: evidence from structural and proteomic analysis.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In studies on molecular mechanisms of simulated μG, the majority of regulated genes and proteins were related to insulin resistance, metabolism, and reduced protein synthesis.

    “Careful studies on the molecular mechanisms revealed that the majority of regulated genes and proteins were related to insulin resistance, metabolism, and reduced protein synthesis [170,171,172].”

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.
