A look ahead at the New York City Marathon We’ve wrapped our heatstroke series now, thanks to everyone for questions, comments and stories. The series was quite technical, heavy on the calculations and concepts, but hopefully provided some food for thought, and the realization that heatstroke is not simply the result of exercising in hot […]
Fluid, heat & thermoregulation
Heatstroke continued
Yesterday, in our second post on heatstroke, we introduced the concept that the attainment of a body temperature above 41 degrees Celsius is NOT POSSIBLE due solely to environmental conditions, which is how you’ve probably always been told to think of it. We explained how body temperature is a function of heat loss and heat […]
Heat stroke dissected
Continuing on from our post two days ago, we are looking at heatstroke, a condition where the body temperature rises above 41 degrees celsius (this cut-off is somewhat arbitrary, it has to be said, at least in the exercise literature). In that post, we introduced some of the paradoxes of heatstroke. The classic teaching on […]
Heatstroke: Some interesting observations
Heatstroke: The reality doesn’t fit with the perception One of the more interesting ways in which we can study physiology (especially during exercise), is to observe it when it fails. Take for example the Calvin and Hobbes equivalent of “failure physiology”: Calvin (the young boy, for those who haven’t discovered Calvin and Hobbes) asks his […]
Exercise in the Cold: Part II
While we are all still thinking about the , we thought we would carry on with our series on exercise in the cold. Most of us are still firmly in the depths of the northern-hemisphere winter, and so we hope you found relevant—it was meant to introduce some basics of heat loss and temperature regulation, […]
