Thank you Dr. Matthews for this playlist, I am a sport science student and your vids really helped me a lot. It would be really awesome if you were to write your own book about ex phys.
Hey Dr. Evan, your channel has been super helpful for my upcoming exam on Exercise Physiology. So topics that I struggle in are 1. Blood Flow and Blood Pressure, and 2. Transport and Utilization of Oxygen. Do you have any recommendations on videos to watch to study for those two? Any help is appreciated.
Dr. Matthews, why would the body want to increase urine production during acute altitude exposure when it is dehydrated? Does this mean Hg and HCT regulation takes precedence over HR and blood pressure control? After discovering your channel I feel like I would love to study under you one day.
Yes a decrease in plasma volume has the benefit of concentrating hemoglobin. I'm not familiar with the intricacies of this area of physiological research. So I'm not able to say for sure if this has a direct negative impact on BP or HR. I'm glad to hear these videos are helping you.
Hi Bernard Zjakić. I intend to update this lecture in the coming months. In my updated lecture material I took out the information on the lactate paradox. I've been reading a bit about this recently, but if you have any good academic resources on this topic you could provide via link I would be appreciative. George Brooks seems to suggest that lower blood lactate during maximal exercise is due to the lower achieved workload at maximal exercise. Submaximally, the lower blood lactate during exercise after acclimation to altitude is because "the sympathetic response to altitude is blunted with acclimation such that blood epinephrine, [lactate], and lactate Ra (i.e., rate of appearance in the blood) are reduced compared to acute exposure, but not compared to sea-level normoxic exposure."

Dr. Matthews your methods of presentation is so great. i would like to say go ahead(from Ethiopia-Africa)
Thank you!

Thank you. I'm glad they are helping. Unfortunately a textbook is not in my immediate future, but thanks for the encouragement.
Brother your work really is amazing..
You made it look easy ..
This will definitely help me in my research..
Thank you again brother 🍻🍻
I'm happy to hear it helped. Good luck!
Hi Dr. Matthews. Thank you for uploading these videos which are well made and very informative.And your teaching is very clear and comprehensive.
Thank you!
This is very useful for my upcoming exams on Intermediate Exercise Physiology! Thank you Dr Evan!
I'm glad it helped.
Hi! Dr Evan i'm actually studying hypoxia, so your explanation helps me a lot! Thanks for sharing :D
I'm glad it was helpful!
You are the man. Thanks for that explanation.
You are welcome.

Really informative 👌

U r great

Why we are able to increase RBC during high altitude training
The lower blood oxygen stimulates the release of EPO causing the creation of new red blood cells.
@@VivoPhys thank u
There is no paradox but Crebs Cycles o2 and pyruvates reStores ATP by aerobic mechanism..
