Mechanisms of Estrogen Influence on Skeletal Muscle: Mass, Regeneration, and Mitochondrial Function
AbstractHuman menopause is widely associated with impaired skeletal muscle quality and significant metabolic dysfunction. These observations pose significant challenges to the quality of life and mobility of the aging population, and are of relevance when considering the significantly greater losses in muscle mass and force-generating capacity of muscle from post-menopausal females relative to age-matched males. In this regard, the influence of estrogen on skeletal muscle has become evident across human, animal, and cell-based studies. Beneficial effects of estrogen have become apparent in mitigation of muscle injury and e...

Changes in homocysteine and non-mercaptoalbumin levels after acute exercise: a crossover study
CONCLUSION: These results indicate that the plasma Hcy concentration first increased, and then the non-mercaptoalbumin/mercaptoalbumin ratio increased as the elevated state was maintained. This study revealed that 65% heart rate reserve, 40 min of acute exercise increased plasma Hcy concentration and non-mercaptoalbumin ratio.PMID:37062848 | DOI:10.1186/s13102-023-00656-w

Effects of 6 weeks of betaine or C-phycocyanin supplementation associated or not with wheel running on redox status
Conclusion The diet supplementations alone appear to have stronger effects on redox balance than the exercise training alone. It could be interesting to evaluate whether betaine or C-phycocyanin could modulate the oxidative stress and inflammation, which occurs during pathologies such as cancer.

Effects of exercise training and nebivolol treatment on atherosclerotic plaque development, iNOS expression and antioxidant capacity in apoE −/− mice
Conclusion While aerobic exercise training reduces antioxidant activity in the liver, nebivolol treatment attenuates atherosclerotic plaque development in apoE−/− mice, but the expression of iNOS is not affected. The combination of treatments does not add on benefits.

Effects of exhaustive exercises, with different intensities, on oxidative stress markers in rat plasma and skeletal muscle
Conclusion Incremental exhaustive exercise elevates the plasma PC levels and TAC, but does not change skeletal muscle oxidative stress markers in rats.

Antioxidant Supplementation Protects Elite Athlete Muscle Integrity During Submaximal Training
CONCLUSION: The muscle membrane integrity of elite-level athletes is compromised even during steady-state running of moderate intensity and duration. The AS provided a protective effect, with evidence that a serum α-TOH concentration of around 12 mg·L-1 is required.PMID:35008040 | DOI:10.1123/ijspp.2021-0051

Muscle Fatigue Is Attenuated When Applying Intermittent Compared With Continuous Blood Flow Restriction During Endurance Cycling
CONCLUSIONS: The attenuation in fatigue-induced reductions in maximal force suggests that i-BFR exercise could be preferable to c-BFR in improving exercise capacity, with considerably less biologic stress elicited from HI exercises.PMID:35551112 | DOI:10.1123/ijspp.2021-0523
