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.
A new imaging study of professional boxers and mixed martial arts fighters finds that repeated head trauma appears to push the brain’s glymphatic “cleanup” system into overdrive at first, before its function declines with increasing knockouts. The MRI-detected changes, to be presented at the Radiological Society of North America’s annual meeting, could offer early warning signs of future neurodegenerative risk.
