Prevention of exercise-induced muscle membrane damage by oestradiol

Bär, P.R., Amelink, G.J., Oldenburg, B., Blankenstein, M.A.·1988·Life Sciences

Abstract

Exercise can damage the muscle membrane, followed by leakage of certain muscle proteins into the bloodstream. This postexercise response differs for males and females; as an explanation for this difference it has been suggested that oestrogens have a protective effect on the female muscle membrane. We recently developed an animal exercise model in which postexercise damage can be studied in laboratory animals in vivo. A postexercise dimorphism, similar to that in humans, exists in rats and indirect evidence for the involvement of oestradiol (E2) was found. We report here 1) that ovariectomized females show postexercise damage like males, 2) that this response can be prevented by E2-replacement before exercise, and 3) that males, after E2-treatment, no longer show postexercise muscle damage. We therefore conclude that oestradiol indeed plays an important role in protecting skeletal muscle, both in females and in males.

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

  • Studies on muscle repair following exercise-induced injury highlight a sex-based difference in which higher levels of muscle creatine kinase (indicative of injury) are observed in male than in female rats following injury. Following OVX, levels of muscle creatine kinase in females are similar to levels in injured males.

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.
