Stephen Thom, MD, PhD, and his colleagues from the University of Split School of Medicine in Croatia, published the article titled “Exercise Before and After SCUBA Diving and the Role of Cellular Microparticles in Decompression Stress” in the January issue of Medical Hypotheses. Their observations contribute to the ongoing examination of the role of venous gas emboli in decompression sickness. Elucidation of the effect of pre-dive practices such as exercise, ingestion of antioxidants, and hydration on an individual’s response to dive stresses could lead to applications in the management of diseases that involve endothelial dysfunction and microparticle production.
