Migratory Birds & Endurance Training…

Migratory birds are extraordinary endurance athletes – and their feats require some serious preparation. In the weeks before take-off, many undergo extreme physiological changes (Vernimmen, 2017). Most obviously, they load up on fats. In many cases, that means temporarily supersizing their digestive organs to ingest as much food as possible. Then, immediately before departure, they shrink their digestive organs to… Read More

US Army Soldiers: Sickle Cell Trait & the Risk of Exertional Rhabdomyolysis

Research Paper Title Sickle Cell Trait and Rhabdomyolysis among U.S. Army Soldiers. Background Studies have suggested that sickle cell trait elevates the risks of exertional rhabdomyolysis and death. We conducted a study of sickle cell trait in relation to these outcomes, controlling for known risk factors for exertional rhabdomyolysis, in a large population of active… Read More

What are the Haematological Adaptations to High Intensity Interval Training (HIIT) in Temperate & Hot Environments?

Research Paper Title Haematological Adaptations to High Intensity Interval Training (HIIT) in Temperate and Hot Environments. Introduction Blood volume is one determinant of cardiorespiratory power and capacity, and is believed to play a role in health and disease. Blood volume, and its components – plasma volume (PV) and red cell volume (RCV) – increase modestly… Read More
