Story summary

Disrupting the muscle's internal clock, a frequent issue for shift workers, hastens muscle aging and diminishes strength, according to research from King’s College London. The study, conducted on zebrafish, reveals that a malfunctioning clock hampers protein turnover, resulting in symptoms akin to sarcopenia. This underscores the vital role of circadian rhythms in maintaining muscle health and suggests new treatment avenues for shift workers.
