Why Does Iron Nutrition Matter?

Introduction While the role of iron in forming haemoglobin in red blood cells (required to transport oxygen around the body to produce energy) is widely understood, many people struggle to meet their iron requirements. This is something that can seriously dent performance during activity. This article attempts to answer two important questions: Why is iron… Read More

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

Type 1 Diabetes: Sensor, Pump, Action!

Research Paper Title Home Use of an Artificial Beta Cell in Type 1 Diabetes. Background The feasibility, safety, and efficacy of prolonged use of an artificial beta cell (closed-loop insulin-delivery system) in the home setting have not been established. Methods In two multi-centre, crossover, randomised, controlled studies conducted under free-living home conditions, the researchers compared… Read More
