Dr Glenn McConell chats with Associate Professor Nisha Charkoudian from the US Army Research Institute of Environmental Medicine, Natick, Massachusetts, USA. She is an expert on the effects of extreme environments on exercise capacity. We talked about dehydration, electrolytes, effects of humid vs dry environments etc. We also discussed the importance of considering sex as a biological variable. This included including both sexes in studies even if underpowered to examine both. We then discussed the importance of conducting more studies on thermoregulation and blood pressure with aging. A very interesting chat.
0:00. Introduction
3:45. What is the definition of extreme environments?
5:05. Who gets the hottest/has the most issues with heat?
9:00. Effects of humid vs dry environments and hydration
12:05. Should drink until urine is clear before a race?
16:10. Should people worry about electrolytes?
20:44. Sex as a biological variable. Women not more fragile etc
23:30. Sex differences in heat acclimation
25:20. No difference in risk of heat stroke between the sexes
25:50. If no difference then just study one sex?
27:38. Need to include women even if small sample
32:34. Even if underpowered it’s ok to include both sexes
40:20. Gender vs sex, binary vs non binary etc
42:00. Women and blood flow/blood pressure/heat etc
