KNOWLEDGE SQUAD! 💪
Thank you, doctor G! Who’s the MVP in the science-based fitness community? DOCTOR G IS THE MVP IN THE FITNESS COMMUNITY! 🔥😎
🙄
This was AWESOME. Love the "test yourself" set up at the end. Really helps for some intelligent and effective programming. Thanks so much!
These videos are gold. Thanks Dr. G!
Great and informative video
Such a knowledgeable guy!
Hey Andy thank you so much for your videos! You're an amazing teacher and I really appreciate them. They're helping me a lot with my studies. I don't have enough money to donate right now, but when I do, I will! Thanks again!
Best one yet! Great work!
Listened to you with Huberman. Love your no bs and science based approach!
I m really happy to watch your videos... Man thank you a lot
Dope as video Andy. Cheers man. Some of these elements were a bit of review for me as I'm an ex-Ex Phys student from a couple of years ago. I wanted to refresh this knowledge but without having to dig through all my textbooks as I'm back in training. Great stuff, keep at it.
i can listen to you all day :)
u the man Dr G. Thank u for all u do
Good talk man! Thanks a billion!!
awesome video as always. Would love to see that video on getting your body back to a parasympathetic state.
Thank you sir
Thanks Andy. Would be great to also consider the impact of air temperature & humidity on endurance failure.
LOVE FROM PORTUGAL!!!
Andy, I love your videos man. Would you be willing to share the answers to your quiz at the end?
I'd pay (donate) for a video on the pros and cons of different breathing methods, or however you think is best to present active breathing. I've been interested in the Wim Hof breathing method recently
damn 🙏🏼 THANK U SOOO SOOO MUCH
💪🏼💪🏼💪🏼 endless thankful to u brother
much love 🙏🏼💧☯️🔥
Great video, thank you so much! So I have a few questions:
1) You discuss that the same amount of O2 is in the air regardless of elevation, and what actually changes is pressure. So what are your thoughts on Altitude Training Systems, such as those found at hypoxico.com/ - specifically the 'at rest' systems that utilize "live high, train low” and achieve the benefits associated with exposure to hypoxia during sleep?
2) Around the 53:33 mark you discuss the need to warmup and even train the intercostal and diaphragm muscles - so what are your thoughts on training (Steady State or Inteval) using a high altitude training mask? That would make it harder to breath period, which should help train the intercostals and diaphragm, correct?
I love this channel! Would you be able to recommend some ex. Physiology books to read?
love your podcost
Hi Dr. Galpin,
I had a question about cramping. i play basketball and I am on Paul Fabritz PJF Program, while also losing fat and weight to lean out and improve my athleticism. i have a recurring theme lately where i know longer cramp in my thighs or glutes, but my calves predictably give out and begin to cramp up whether during my workout or a game I don't tire out just cramp up, and i last around 2-3 hours and then i'm done. i just wanted to know what can i do to get rid of this issue. Plus have a good diet
So much fun to learn from you lectures. Love your analogies! Just why would you use a house for a fuel? :D 48:54
Thanks for this- easy to follow. It's perhaps outside the scope of this lecture, but I'm curious as to how heat management plays into this. I know that particularly with distance runners and cyclists, there have been studies done showing that both precooling and cooling during exercise to significantly increase performance and some discussion of overheating being one of the main performance limitations for highly trained endurance athletes. I assume it comes down to the limits on our ability to remove what is technically a waste product, but it's not clear to me what the points of failure are.
eta: oh, wait. we mostly cool through sweat. excessive sweating leads to increase in blood viscosity, reduced stroke volume, maybe increase in bp leading to less efficient gas transfer in capillary beds? As all this happens the body prioritizes blood volume over cooling and then everything starts to heat up. And I'm sure there's a mechanism whereby under normal circumstances we get nowhere near the failure point. I dunno. Guess I should've opted for this in undergrad
I've been programming for muscular endurance butI. Switching to high intensity and I was wondering if I should increase reps or sets, and how much volume I can increase at a time
I'm hoping one of Professor Galpin's students can answer this for me, if I am a long distance runner mainly racing half marathons and below, and never race the full marathon, I'm fairly diligent about intaking enough carbohydrates and suspect I'm never running too low on muscle or liver glycogen. What are the main bottlenecks that i should aim to improve with training? From my own understanding its muscle metabolic speed (mitochodria), blood capillary density, heart stroke volume. These systems for the most part are trained with slightly below threshold runs and longer slow runs. Am I missing anything major?
What exactly is the difference between an increase in mitochondrial respiration capacity and increase in mitochondrial desity? To me it seems that both adaptations achieve the same goal of increasing the aerobic capacity of a muscle, one by making the existing mitochondria more capable and the other by adding more units, but since both adaptations seem to be associated with different types of endurance, how do they differ?
Thank you for the great content
Dr Galpin I had a question regarding cardiac output, sv and HR. I have been doing HIIT & tempo cardio training for the past 5 months. I recently did a beep test and have adhd, and take adhd medication. I feel as if the adhd medication gives me more mental endurance and decreses my physical endurance, but the mental endurance allows me to go for longer. Why is it that adhd meds, like amphetamine, results in this. Could you explain physiology. I'm guessing it's because the adhd meds, increase heart rate, for the same vo2, meaning your working harder than normal, undermining actual performance or efficiency. I got level 5 or stage 5 on the beep test, but feel I would have gotten more, if I didn't take the adhd meds. I felt dehydrated and done after stage 3.
Could you provide a link with all of the answers to the homework assignment you gave us at the end of the video? I worked through it but want to check my answers! Thanks Dr. G!
did you do the BJJ belt system on purpose 57:12
Do you analyze Vo2 max for a fee? Im a nose only breather & was told my results was A typical. Never seen a results like mine. 51 year old with 51 Vo2max. Since the have improved every aspect of my exercise Nose Only breathing. Great videos :). Accidentally found them.
Question: saw your Vid and also research paper on fat leaving the body in form of co2 and water. Does it mean we always lose fat? its just the volume depends on intensity of breath(I.e oxygen uptake)?
Not exactly, because you have to consider the other end of the spectrum...i.e....how much you consume
@@drandygalpin so, when does fat actually start to oxidize? Any way to know that?
Considering daily life, don't we oxidize both fatty acids and glucose throughout the day at similar rates? Also, regarding fatty acids, which one oxidaize first, the ones t hat we just ate or adipose tissue fat?
@@shermirsaliev5227 Fat gets movilized (lipolysis) and burn (beta oxidation) preferentially at low levels of intensity of physical activity. If you conduct yourself an ergospirometry, it´s gonna give you the volume of O2 you´re consuming and the volume of CO2 you´re expiring; If you divide your CO2 volume by your O2 volume you get your RER (respiratory exchange ratio), a number between 0.7 to 1 (or above), the closer you´re to 0.7 the more fat for fuel you´re using and when you get to 1.0 you´re on carbohydrates almost 100%. As Andy said, fat balance is another issue, because one thing is to use a certain amount of fat as fuel, and another is whether you´re gonna lose body fat, because that depends on your everyday energy balance. As for which fats we oxidize preferentially, it would depend on several factors like gender, level of trainin, etc, but mostly in exercise, in trained athletes, it´s gonna be intramuscular triglycerides, with some amount of adipose tissue TAG. Hope this is not confusing at all, Andy please feel free to correct if I´m mistaken.
If you've not already made the video on breathing, I would 100% be interested in what you have to say on the subject.
would "Metabolic speed" have anything to do with having to warm up? feeling real stiff until nutrients get into muscle?
Not really.
Breathing videooo!!!! Please!!
why exercise increase in later part of exercise with little effect
Can't get I to Stanford no problem Stanford will come to you ♥️💪🏾
I'm going to come back and do the homework. Promise.
More more

All in All, it's S O D I U M at the G R I N D...
dude, you look blazed AF here
My HR is 125 just by watching this video
how about the brain? i fail alot sooner if im not motivated
How do we heighten pH if it becomes acidic after workout?
is enough to stop the activity or slow down to produce less H+ and it heightens by itself. Tha body has it's system to maintain the equilibrium. The H+ is buffered by the bicarbonate in the blood to form carbonic acid which gets dissociated to form Co2 and H2O
Limitations of long duration excersize
1. Nerves -running out of carbs
2. Muscle - running out of glycogen, pH drop especially if running above threshold pace
3. Blood - maintaining glucose, transport of waste products at higher pace. Minimal limitations at below threshold pace
4. Liver - converting glycerol & lactate to glucose. Minimal if any limitations
5. Heart - maintain low heart rate to minimize limitations.
6. Lungs - minimal limitations at a lower pace.
I am from dr humberman
Why do we breathe? Oxygen is the most important molecule that sustains the human body, you can survive without water for 2-4 days, without food (that you need to produce ATP) for weeks but after 2 minutes without Oxygen you will die. So I'm not very convicted with your explanation that we want 02 to produce ATP. Yes, we need 02 to produce ATP, but we need oxygen to stay alive.
No, no no! What you tell us at 37:00 is wrong. It has nothing to do with pressure of the blood, just about more volume, making the ventricle to expand more - nothing else. At 46:00 minutes you tell us that the blood, is coming from the right artery and into the left ventricle. That is actually wrong, oxygenated blood are coming from both, right and left side arteries (usually 4 arteries) and into the left atrium and then to the left ventricle. At 49:00 minutes you are really out of your mind, talking about oxygen... Oxygen not being energy! Ever heard about the phosphate in the end of the ATP process? Heard about the eletronchain or carboxyl and carbonyl... Man, Y have a lot of work to do, but by all means - keep up the good work!
Why do we breath? REALLY??? How old is the audience for this channel?
