Abstract

Surface electromyography (sEMG) is a popular research tool in sport and rehabilitation sciences. Common study designs include the comparison of sEMG amplitudes collected from different muscles as participants perform various exercises and techniques under different loads. Based on such comparisons, researchers attempt to draw conclusions concerning the neuro- and electrophysiological underpinning of force production and hypothesize about possible longitudinal adaptations, such as strength and hypertrophy. However, such conclusions are frequently unsubstantiated and unwarranted. Hence, the goal of this review is to discuss what can and cannot be inferred from comparative research designs as it pertains to both the acute and longitudinal outcomes. General methodological recommendations are made, gaps in the literature are identified, and lines for future research to help improve the applicability of sEMG are suggested.

  • The inherent limitations of surface electromyography analysis preclude the ability to draw inferences as to motor unit recruitment.

    “However, the inherent limitations of surface EMG analysis precludes the ability to draw inferences as to motor unit recruitment [68].”

    From Loading recommendations for muscle strength, hypertrophy, and local endurance: a re-examination of the repetition continuum. (2021) · cites this paper as [68]

    In “Acute and mechanistic variables,” the paper says sEMG amplitude alone cannot establish motor unit recruitment. The claim extends that limitation to surface EMG analysis generally, whereas the same section notes that other sEMG methods can investigate recruitment, albeit with questionable validity in some conditions.

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.
