Acute Responses to Aerobic Training | CSCS Chapter 6

[@willhopkins4197]

It's so interesting to see how much changes so quickly in your body. I also had never thought about the fact that we need to breathe more comes less from needing more oxygen, and more from needing to get rid of CO2.

[@melanieweirich8482]

Local circulation was something from the reading I didn't understand completely. So this was super helpful.

[@evaozimec]

It's so cool how our body knows how to control the circulation of blood in response to exercise by dilating arterioles to send more blood to working muscles and constricting arterioles to reduce blood flow to other organ systems.

[@julianasum8481]

This video helped me to understand all the different physiological changes that happen when undergoing aerobic training.

[@charmenatchison854]

More clear than reading the chapter. Glad I now know what systolic and diastolic means and also why it's important!

[@emilywalker9462]

This video was super helpful, and the clear path made it simple to follow and understand. I have heard about cross country skiers having a high VO2 max before but it still amazes me, because it is not a common sport/athlete in the US.

[@jupshaw]

This video allowed me to summarize and expand on what I already learned about aerobic exercise. Great info!

[@dimitricarrion6145]

I liked that you went over the difference between systolic and diastolic blood pressure. That was good review for me because I always mix them up.

[@morganrolleri9198]

This video was a great reminder of calculating max heart rate and cardiovascular responses!

[@jamarmack9626]

I really enjoyed learning about why cross country skiers have higher VO2 maxes because I would've never thought that this would be a sport related to having high VO2 maxes.

[@chrismangram8463]

thank you for walking us through the steps with every formula

[@coachoscini1315]

Dr. Jacob, you are the single coolest guy. Ever. Thank you so much, man.

[@kelli-lynroche8446]

This video was very helpful in understanding all the acute physiological responses during aerobic training. I did not know that systolic blood pressure increases, while diastolic BP decreases.

[@dereklinck2672]

Great material on the acute responses to cardiac output and the systolic and diastolic changes in the body as a response to aerobic exercise.

[@ameliabrock]

I had no idea what tidal volume was before this, thanks for the rundown :)

[@jakegellatly8261]

I really liked learning about how the systolic and diastolic portions of the heart are affected differently by intense aerobic exercise

[@lexireynish5892]

This video was so helpful in understanding the benefits and physiological changes that occur during aerobic training!

[@DevanneyBoyd]

I remember learning about these cardiovascular components in A&P. This was a good review!

[@user-sd3sv7uq7f]

This videos is so helpful for undertanding how important the physiological changes are during aerobic training! Not many take this into consideration

[@celinegriffin3244]

This video was a great recap going through stroke volume and cardiac output. As well as showing how to calculate max heart rate!

[@madelinehernandez8838]

Learning about respiratory responses to aerobic exercise was interesting! For those who are healthy, we increase breathes from 12-15 breaths per minute to 35 to 45 breaths per minute. Great knowledge.

[@joyshang5670]

Thank you for explaining the unoxygenated and oxygenated blood cycle! I got a little confused but now understand it much better.

[@drewamato5467]

The pressure gradient overview in this is very helpful, especially for ex phys.

[@macynunez4455]

This was such a great recap and review of what we learned in ex phys! So cool how our body responds so quickly to enable us to exercise!

[@matthewwadley4348]

The cardiovascular responses were fun to learn about and read. Specially how they control local circulation with how it redirects blood flow from organs to active muscles

[@moirabryson5042]

I didn't realize how much aerobic exercise affected our bodies acutely especially how our tidal volume can really increase from the resting rate of 0.4-1 L to as much as 3 L or greater. Thank you!

[@wyattcarlson7504]

It's always interesting to see the fold increases when it comes to physiological aspects like ventilation. For example going from 12-15 bpm to 35-45 bpm.

[@braedenmoore3743]

I enjoyed learning about the two different ways to calculate maximum heart rate. I have been using the 220-age formula in my classes but forgot about the 208 - 0.7 * age method.

[@clairemasterson6031]

This has been a great review of many of things from other Kines classes!

[@lucamarin8565]

This video goes hand in hand in what were learning about in exercise physiology. It helped build on my understanding.

[@madelinejewelnebril2871]

I recently reviewed these concepts in exphys and it's interesting to see the connection and affects to acute aerobic exercise.

[@juanrossi3]

Thanks a lot dr Jacob for such a high level lecture and for your tremendous generosity in sharing it with us.

[@jadenrea1109]

Each section of this video was super helpful in reviewing and explaining the key terms and principles that are a part of acute responses to aerobic training. Thank you for being clear and concise!

[@torilucht5871]

This video was very informative and I appreciated the information! I was surprised at how many factors in the body are increased with aerobic exercise.

[@TRamos-pl6oo]

It was really interesting to me how the more muscle mass you are using increases the oxygen demand in the body. This really makes since when choosing different exercises such as rowing machines and wind bikes can be much more beneficial than something like a stationary bike.

[@jakegonzales1367]

I really enjoyed the section in which the cardiovascular systems works in regards to shunting blood to the muscles rather than the organs. Our body’s are so interesting!

[@devynpryor8228]

We're also reviewing this in exercise physiology! So nice to double down on information about acute response to exercise.

[@cameransherwood5157]

This video was great because its connecting with a lot of what we are talking about in Exercise Physiology and the different changes in BP and SV when we endure working out!

[@BrianaReynoso]

this video was a great refresher and really helped answer my questions after reading the text

[@avajgallo]

You explained the material really well - it makes me want to learn more thanks!!

[@hannahb872]

I appreciated you reviewing what the results from acute aerobic exercise caused within the heart! The amount of times I've had to review what SV, CO, preload, and afterload do within the heart because of nursing school. But it is refreshing to hear how exercise affects these readings!

[@audreyoates3242]

I really appreciate the breakdown of the acute responses to aerobic training. We're learning about this in ex phys so this is a very helpful video!

[@bensonmutuvi8429]

Great recap and clarification of what I’ve learned from past classes. Love the beard look too.

[@emmasanchez5975]

It was really cool to hear about the cardiac output and VO2max because we just talked about that in nutrition! I really enjoy making the connections between the classes.

[@coreycollier973]

This was a great recap of things we've learned about cardiovascular and respiratory mechanisms in the past.

[@MatthewDuPrey325]

I found this video to be very interesting and was such a great recap of the sections also I really find it interesting how things are able to increase by so much such as the Minute ventilation

[@alannabergherm8046]

thankfully, I'm already subscribed so my type IIx fibers are staying type IIx, thank you very much

[@emilydonahue8216]

This was such a helpful recap of cardiovascular terms and concepts that can be confusing!

[@isabellecousineau302]

A throwback to Ex Phys material!

[@fabianschindler1019]

Okay now I definitely have to subscribe. Who wants all the Typ I fibers 😂

[@tianguyen3897]

I was very interested in all the math covered in this section! I never knew calculating the maximum heart rate could be as easy as subtracting age from 220.

[@Adam.gates_]

It's crazy to put into picture all of the acute responses that go into exercise. It is much more than just increase heart rate and respiratory rate.

[@oliviadyck510]

Thank goodness I am subscribed so that all my Type IIx fibers don't randomly spontaneously convert to Type I fibers!

[@joshcombs123]

I have always been curious about the difference between respiratory differences between aerobic and anaerobic activity

[@aribhalla9820]

This was a great review of exercise physiology!

[@myawilliams8357]

I haven't thought about making sure you are using every musculature as possible so you get more oxygen pumping through the body. Such as doing an exercise that both uses your arms and legs like you rowing instead of a stationary bike.

[@hayleesaurette1798]

i think it is crazy to realize that the heart just has to put up with whatever we decide to put our bodies through. It is the one that constantly has to meet our demands.

[@thelmasepulveda4481]

It was interesting to know that cross country skiers will have a higher VO2 max than other athletes!

[@ryanharris8481]

I found it interesting that with vigorous exercise, 90% of our cardiac output can be distributed to the skeletal muscle vs 15-20% at rest

[@redarachi3621]

Big thanks

[@caleighgarcia7792]

I was not expecting to hear the words "super woke" when you were talking about meditating and the number of breaths. This caught me off guard and I even had to show my roommate because of how funny it was to me!

[@brysonhashimoto2878]

I find it very interesting how systolic pressure will increase and diastolic pressure stays the same during aerobic exercise.

[@joshuawada8783]

It said all my type IIx fibers will convert to type I's. I gotta subscribe again just to make sure.

[@clarisamarin7284]

Interesting how the control of local circulation percentages are so polar.

[@NAKMUAYACADEMY]

Another great video!!!!! Some questions if possible to point me in the right direction: Is slow steady cardio 2-4 times a week better for overall health or maybe better do 1 slow and steady and 1 hit style cardio for general population ( 40-60 years old) As well would you do slow and steady cardio on recovery days ? Or better full rest ?

[@DrJacobGoodin]

Great questions Coach! It depends on specific circumstances and goals, but in general 1x/week low intensity cardio is enough to maintain cardiovascular health but not to substantially build it. I'd say that 2-3x/week is a sweet spot. But if the individual is also engaging in rigorous team sport activities, then they may not need to do additional low-intensity cardio. If the individual is currently doing nothing, then 3-4x/week of steady low intensity cardio, and 1-2x/week of HIIT style training would be recommended.

[@NAKMUAYACADEMY]

@@DrJacobGoodin thank you for reply Coach ! I forgot to ask what is specific heart adaptation in regards to slow steady cardio ( is it bigger heart and more blood out put - lower pressure) and hitt style ( thicker walls of the heart and faster blood output but higher pressure? Is that correct ? Last but not least what's best formula to establish max heart rate and slow steady heart rate ? I was using 220-age for max and 180 - age for slow ? Curious your thoughts

[@zoiezantua7002]

it's crazy that cardiac output can reach up to 90% during crazy high intense exercise

[@keonihughes4242]

Interesting to see that cross country skiers have the highest VO2max. I wii on Ike have thought it be ultra marathon runners but it makes sense.

[@makennakaczmarczyk7563]

I thought it was interesting how 15%-20% of cardiac output is distributed to skeletal muscle at rest, but up to 90% of cardiac output can be distributed during vigorous exercise.

[@rozalynnlarson8835]

I was surprised to learn that the cardiac output to skeletal muscle during vigorous exercise increases to about 90%

[@laurenomalley2778]

I thought it was really interesting to learn why cross country skiers have a higher VO2 max than runners usually.

[@kennyvogan5673]

I can definetly feel that o2 and HR increase right away, even before a start. Is my body getting ready for exercise through compensation, or is it just adreneline?

[@mikestatz5098]

I never understood what the implement was measuring on the Tidal Volume slide when my grandma would use it.

[@_ayeshakhan09]

Plzz answer my question??..........What are the Normal and abnormal response to acute aerobic exercise ??

[@SuperTroyAustin]

How is it that diastolic BP can remain relatively constant?

[@DrJacobGoodin]

Because the only change is that the heart pumps harder (due to catecholamines, increased SV, and the Frank-Starling mechanism), but in between pumps, BP stays roughly the same.

[@jcruz6453]

Hey doctor Goodin this is Jon-Cruz Castro. I'm coaching a few sports and strength and conditioning at my old High School. Would it be okay if I put some of your videos up on my online class for the students to use as another source of information. Such as your at home workouts? Having been taught by you, I can think of no one better for my students to learn form and other techniques from. Thank you, and I hope you and the family are doing well!

[@DrJacobGoodin]

I would love that Jon-Cruz! That's so rad that you're coaching now. Congrats man I know that was a goal of yours. Please don't hesitate to shoot me an email if you'd like to connect or bounce any ideas off me for your athletes. Proud of you dude.

[@jcruz6453]

@@DrJacobGoodin Thank you so much for your teachings, they really help personally and professionally. I'm coaching cross country, track and field, assistant basketball coach, and strength and conditioning.

[@Neveragain188]

❤

[@bojak76]

I be feeling like my breathing frequency is more like 50 breaths per minute when I am doing aerobic exercise.

[@DrJacobGoodin]

Samesies. And it's even worse knowing how it used to feel when I was in tip-top aerobic shape

[@austiniturbe4495]

That's a drastic increase in breaths per minute

[@ChynnaKifer]

I liked the part where you said that one could increase their depth of breathing if they "meditate all the time and super woke". That was really funny thank you!

[@jasonpena3556]

acute aerobic exercise will result in an increased HR

[@kylesands9693]

So cool that we can quantify the work done by the heart, is there any real world application to this? P.S. so woke made me laugh, love the jokes Dr. Goodin

[@Kjay888]

My breath per minute must be around 6 then 🚶‍♂️😆

[@Kjay888]

“If your super woke” 🤣🔮
