#37 - Exercise in the heat, dehydration, fluid ingestion and circulation with Dr José González-Alonso

Dr Glenn McConell chats with Professor José González-Alonso from Brunel Univesity London. We discussed exercise in the heat, dehydration, fluid ingestion, blood flow, metabolism and human circulation. He has a very strong research track record having researched these areas for around 35 years. We discuss how he began his career doing research with some very big names.

16:35. Why cardiovascular drift during prolonged exercise?

19:23. Effect of dehydration on ex performance

23:50. Effects of fluid ingestion during exercise

31:00. Fluid ingestion, adrenaline and muscle glycogen use

33:30. Blood particles (osmolality), dehydration and exercise

36:28. Blood volume, cardiac output and VO2 max

41:30. Exercise in hot and humid conditions

44:24. Central (brain) causes of fatigue during exercise?

52:35. Generalizing results from non elite participants

53:40. Drinking during running vs cycling

56:37. Starting race euhydrated vs hypohydrated

57:50. Only drink a lot if sweating a lot /osmolality and urine

1:00:00. Sweat sodium concentration during exercise

1:02:25. What is still unknown in the area?

Inside Exercise brings to you the who's who of research in exercise metabolism, exercise physiology and exercise’s effects on health. With scientific rigor, these researchers discuss popular exercise topics while providing practical strategies for all.

The interviewer, Emeritus Professor Glenn McConell, has an international research profile following 30 years of Exercise Metabolism research experience while at The University of Melbourne, Ball State University, Monash University, the University of Copenhagen and Victoria University.

He has published over 120 peer reviewed journal articles and recently edited an Exercise Metabolism eBook written by world experts on 17 different topics (https://link.springer.com/book/10.1007/978-3-030-94305-9).
