I´m spanish future PhD student and I wanna congratulate you for this work. These playlists are awesome. I can review, learn, and improve my english at the same time. Thank your for this videos.
Your channel has been absolutely priceless. I'm a cyclist trying to improve my performance and trying to understand my metrics and the underlying physiology. Your comprehensive youtube channel answers most of my needs. Instead of having to scrape around jumping from video to video, trying to get a full picture, your channel reliably gives me everything I need to know. For that, I say thank you!
7:21 it's said that, urine production decreases through sympathetic activity but during fight or flight situations you generally see that the sensation or urge to urinate actually increases. Can you kindly throw some light on it...
Hi Chinmoy Deka. Good question. I do not have an answer for you, but I wonder if the type or degree of sympathetic activity may impact this. The urge to urinate likely increases leading up to something like a scheduled public speaking event, but when suddenly force to run for your life it probably does not increase. So an anticipatory behavioral response may be involved. This is well outside of my area of expertise though. Hopefully someone else will provide a better answer here.
First of all, thank you for the video, very helpful. Also, are there any resources on how to actually apply these physiology concepts into exercise, I mean applied physiology??
Good question. I am not aware of a good exercise prescription textbook that attempts to link prescription and physiology in the same book. It might be out there. I just haven't looked. I typically use ACSM textbooks which tend to be just a list of best practices with minimal physiology.
Hello Dr. Matthews, first of all, thank you for these wonderful videos. At the onset of depolarization; is sodium the only ion that is going to be activated, or does the potassium also get activated in terms of diffusing out of the cell? Continuing from the previous question; is the sodium-potassium pump responsible for the repolarization of the cell? Thank you!
Sodium enters the cell causing depolarization at the beginning of an action potential. Potassium then leaves the cell to cause repolarization. The sodium potassium pump is constantly working attempting to create and maintain the resting membrane potential, but is overwhelmed by the ion movements during the action potential.
Subscribe is sure thing for everyone after this video ,then finish all of your video is next step , thank you for these helpful teaching series and conscientious explaination
When the cell is in the later phrase of repolarization, only the suprathreshold stimuli can make another AP. BUT in the hyperpolarization the subthreshold stimuli is enough for the AP.

You are very welcome.
Thank you very much, amazing to have people like you
Your welcome.
Sir can you tell me the reference book and which edition?
I use a blend of the exercise physiology text books of Larry Kenny and Scott Powers, but I also incorporate other resources.
@@VivoPhys ok thanku sir
Thanks for this video series. Do you happen to have the powerpoint printouts uploaded somewhere?
Sorry. At the moment I have not uploaded the notes anywhere.

I know a few for muscle and strength building, if that's what you are looking for?

You are very welcome.
Can you share pdf notes of these classes, like transcripts?
Sorry. To maintain value for my universities students I have decided not to share my PowerPoint files and notes online.
@@VivoPhys ok sir, I understand. Thank you.

I f**** LOVE YOU! Thank you for saving me time from spending hours trying to teach myself!
I'm glad it helped.
Thank you so muchhh doc evans.. ☺️☺️☺️
:)
Thank you amazing explaining ♥️♥️
You are welcome.
sir can u give us the slides ?
Sorry. I reserve my slides for my university students.
thank you doc!
I hope it helped.
@@VivoPhys absolutely!! im not a student or anything and i was able to follow along with little effort, i love it!
Thanks for helping
I'm from iran
You are very welcome.
Thanks Dr
I'm glad it helped.
