The problem is the lactic acid may be low in the blood but not necessarily low in the muscle tissue. Just because the blood is low or slow twitch muscle cells pulled it out of the blood, does not mean most it can't still remain in the fast twitch muscles cells. Think of high blood sugar for example, glucose can clear out of the blood by going into muscle cells, but it does not mean the sugar is "gone" simply because the blood level is low. Remember you are saying "it's probably not the cause" but that is really not a way to prove a myth is incorrect. The soreness is not in the "bloodstream" but in the exact muscles that were worked out. Lactic acid "removal" is again a reference to the blood stream not the muscle tissue itself (the sore ones). Muscle with a high proportion of fast twitch muscle does not have the blood flow slow twitch muscles do. I am starting to believe DOMS is a slow twitch muscle phenomena. I can actually set a clock to my muscle soreness to 48 hours and it occurs each and every time of a muscle building workout. I don't believe routine muscle soreness from rebuilding muscle tissue is DOMS. DOMS can occur in a muscle was not not targeted at all and was not sore or tight in any way after the work out. It's like a total surprise.

Hello Evan great content, just what i was looking for one question I wanted to ask when we correlate this to %'s, you said anything over 1.020 would be considered dehydrated. where would we say an individual is 100% hydrated 90%, 80%. 70% and so on. hank you again for your time
@VivoPhys
@VivoPhys 9 күн бұрын
It would be difficult to determine hydration percentage in this way, and people would likely draw thresholds at different levels. The following sentence is from one of my published papers. "It should be noted that some have recommended different urine specific gravity thresholds for euhydration (1.013-1.029g∙mL-1 (Armstrong et al. 1994))."

Wow thank you so much, this was very helpful as a review on endocrine exercise physiology. Endocrinology has always been a tough subject to wrap my head around because of all of the different hormones that are secreted makes it so very overwhelming. This video helped me better grasp the understanding of hormone physiology as well as the main hormones I'm concerned with for my major instead of writing every hormone out on a list and picking which ones are used during exercise.... Anyways, Thank you Evan, you do great work and this video could not have been formatted better! Hopefully one day I will find the time to master the endocrine system and memorize every hormone and it's physiology. This will have to do for now though! 😅

CORRECTION: In the video I used the following formula to calculate p values (=TDIST(ABS(([rValue]*SQRT([nSize]-2)/SQRT(1-([rValue]*[rValue])))), [nSize], 2)). The last [nSize] is the portion of the excel function where the degrees of freedom is entered. This should have been [nSize]-2. I accidentally left out the -2. Fortunately, it makes minimal difference with typical sample sizes. My quick testing suggests that it only matters at the 3rd decimal place with sample sizes of at least 10. Once over 20 participants it is a small enough difference that it would not impact reported data as the difference would be rounded away. Regardless, the formula given below has been corrected. CORRECTED Pearson Correlation p Value Formula for Excel: =TDIST(ABS(([rValue]*SQRT([nSize]-2)/SQRT(1-([rValue]*[rValue])))), [nSize]-2, 2)

Hi, I'm quite confused at the claim that PaCO2 increases during exercise and therefore VE (and the graphs that accompanied it). From all the literature I have read, it states PaCO2 is relatively steady/constant in sub maximal steady state exercise, and even decreases in 'heavy' exercise above the lactate threshold.

I'm guessing you are talking about the graph with CO2 on the x axis and ventilation on the y axis. I did say CO2 increases with increases in exercise intensity. I could have been clearer in this statement. CO2 production does go up with exercise intensity. However, as was the purpose of the slide. CO2 is a powerful stimulus for ventilation. So almost as soon as CO2 is produced it is sensed and ventilation increases. So it does not build up in the blood. Prior to steady state being reached blood CO2 level may increase slightly but much of it is likely buffered by the bicarbonate system of the blood.

@ionabethx6107 2 ай бұрын
@@VivoPhys I understand CO2 increases with ventilation, in metabolic demand matching. The part I am confused about is arterial partial pressure of co2, as your graph says PaCO2. All I have read states this doesn't deviate much in steady state exercise, in order to maintain homeostasis.

@ionabethx6107 the graph is not depicting an exercise session. It is showing what would occur if blood CO2 increased. As in an artificial laboratory research protocol.

​@@VivoPhys Yeah, it's a minimal difference in MOST situations, but on the day I found this video, I was trying to calculate the p value for a correlation with only 4 data points! In that case, the difference between using df vs. n in the formula was p=.025 vs. p=0.003. (If anyone's curious, the data points were body temperature vs. hours of REM sleep in various mammals; it's a very strong inverse relationship.)

@adam97202 thanks for responding with your own finding. It's interesting to see that even with a tiny sample size the interpretation ended up being the same (assuming a threshold of p<0.05). That difference could matter though with a weaker correlation.
