Researchers have identified indole metabolites from the human blood bacterium Paracoccus sanguinis that showed anti-aging activity in laboratory-grown human skin cells. The compounds reduced oxidative stress, inflammation and collagen-degrading activity in cell experiments, according to findings published in the Journal of Natural Products.
A systematic review led by Edith Cowan University has found that increasing muscle temperature through warm-up routines can significantly enhance performance in rapid, high‑power movements. The study estimates that for every 1°C rise in muscle temperature, speed- and power-related performance improves by around 3.5%, while maximum strength remains largely unchanged.
