Bioenergetics of Training: 3 Energy Systems | CSCS Chapter 3

[@NathanHanson-gt2kq]

Dr. Goodin does a great job in taking lots of information about energy systems and compacts them into this video. The chart with the different time ranges (exercise intensities) and use of energy systems was helpful.

[@NikoKinesStudies]

I agree Nathan! He is quite the expert and does a wonderful job teaching us

[@trinityhanson3812]

I agree, I thought his explanation was very helpful in understanding these intensities and systems

[@cadentomlin2646]

I liked how you explained the in-between stage of the energy systems between phosphogen and glycolytic systems. I have never heard of that.

[@jakebergherm2786]

yeah that was really interesting

[@joshwillbanks851]

I thought this was really interesting too!

[@KeeganDeBever]

Yeah so true! I thought it was super interesting because I didn't understand it before either.

[@NathanHanson-gt2kq]

Agreed, it is interesting how the body transitions between energy systems

[@Ken-fd7ml]

I completed my bachelor in strength in conditioning in December and am currently studying for my CSCS. I want to say thank you for having these available for free. A lot of study materials are locked behind paywalls. I've been listening to your lectures while walking my dog and driving. They are immensely helpful and highly appreciated.

[@AndrewTheTransformer]

Excellent. Where did you study your S&C degree?

[@oprimecoach1441]

True, thank you Jacob

[@ColtonKetchum]

I always loved looking at the physiology of how our body makes energy, and this video's explanation of anaerobic glycolysis did not disappoint.

[@Jerel_Q]

I agree! Breaking down each energy system was a much needed refresher!

[@JuliaPinnell]

I found it interesting to breakdown the differences between both aerobic and anaerobic glycolysis!

[@RyanDoyle-o4t]

Really like how you take ample time to break down each energy system showing the differences and show which system does for our bodies.

[@JuliaPinnell]

I liked this too, I thought the phosphagen system was fascinating to learn how fast it was!

[@AnnaNovelo]

yes I agree! I like that he broke down each system individually but also how they work together.

[@ZaraHoughton]

This was a very in-depth video, with a lot of information provided about energy systems. I like how you separated the different systems and explained what happens within our bodies during various activities. It was helpful when you split the glycolysis systems into the two sub-divisions, as they are usually taught together. I thought it was interesting learning about the Cori cycle, and the process of lactate getting cleared from our body.

[@jakebergherm2786]

I thought that was also really nice to have it broken down like that and with examples given

[@isabellefernandez-es1ej]

I agree!

[@livingston-b]

I agree! I remember being taught glycolysis and the oxidative system together in high school and not knowing you could go through glycolysis without entering into the Kreb's cycle or the ETC.

[@isabellefernandez-es1ej]

This video provided lots of great information and really went in depth on all of the energy systems. I found it to be super helpful after reading the textbook.

[@livingston-b]

I agree!!

[@AnnaNovelo]

It was fascinating to learn about the three energy systems and how they work in harmony to move and exercise our bodies. The phosphagen system in particular is such a key player and in generating the intial ATP. Also enjoyed finally learning what creatine is, thank you for your breaking it down so clearly.

[@LukeMoore-cx4iz]

I agree, it is crazy to think about how the different energy systems have to know when to activate during different types of exercise.

[@alexiaharlow8565]

This was a great refresher of the energy systems from exercise physiology last semester. It was nice to see it all condensed.

[@unsuidojoneuss]

Thank you so much for having these videos for free. I am in Germany studying for my CSCS and you have saved my behind.

[@cadentomlin2646]

Going global!

[@michaelmapes6500]

So I found your channel just the other day, and it is incredible. I am studying for the TSAC-F certification and these videos are useful for reinforcing studying from the textbook and study guides. The fact that they are free is amazing. And I love the bloopers at the end. I have had to do a lot of recorded presentations during my time in academia, and the struggle is real!

[@DrJacobGoodin]

Well kind sir, this just made my day! I appreciate the kind words and am blessed to know when some of my work has helped a stranger accomplish their goals. Best of luck on the test 💪

[@JA-gt4wc]

Thank you for doing this Video, I'm currently Revising for my Upcoming Exam in January and you cover all the important key topics in Bioenergetics of the Energy Systems

[@AylethLizarraga]

No matter how confident I feel about the energy systems, I will always be making time to find a way to review them and this video was an amazing tool so use!

[@isabellefernandez-es1ej]

This video provided great insight!

[@LukeMoore-cx4iz]

The was a great explanation of the three energy systems. I always get confused with the different paths within the energy systems, so it was good to see some visuals to go along with the word descriptions.

[@trinityhanson3812]

I really enjoyed hearing about the different energy systems and how we can utilize these to improve in our sports and activities

[@danicavenus]

I have been searching for a long time now for a video that explains the energy systems simply and comprehensively and this is the one that's helped all the information come together for me. Thank you. I wish you were my lecturer for Exercise Bioenergetics!

[@DrJacobGoodin]

Wow, thank you Danica!

[@Jerel_Q]

It always amazes me how the body automatically switches from the different metabolic pathways in response to exercise intensity and duration. It really reflects how efficient the body is.

[@LukeMoore-cx4iz]

I agree, it is crazy how complex the human body is.

[@trinityhanson3812]

So fascinating learning about these complex systems which our body to us seems to just do. The efficiency is so cool to learn about!

[@Moniiiqueee824]

This was a great breakdown of the three energy systems! It is interesting how the phosphagen system fuels those explosive lifts and sprints, while the glycolytic system really kicks in during those tough, high-intensity intervals. Your explanation on how the oxidative system helps with endurance, perfect for long runs. Thanks for sharing Dr.Goodin!

[@NoelleDarquea]

This was a great overview of the 3 Energy Systems and how they work together to allow us to perform our daily functions including exercising daily.

[@ameliabrock]

Understanding the phosphagen system, fast glycolysis, and oxidative system seems really important for trainers and coaches to tailor effective training programs! The explanation of catabolism, anabolism, and the role of ATP as the energy currency is easy to follow as you talk :)

[@JuliaPinnell]

I found it interesting that each is dependant on the other and each follows a specific time line . I hadn’t learned about the phosphagen energy system either which was fascinating that it’s only 10-15 seconds but does so much for our body!

[@vanessaviramontesPLNU]

Dr. Goodin, I enjoyed this video as it gave me an even closer look at the 3 energy systems. This has been a repeatedly important topic in all my classes and this video explained it beautifully. This video specifically helped me grasp how the glycolytic energy system works.

[@thomaskinzler]

This video is an awesome refresher for the 3 systems. I think something that is interesting about the videos for me is that they take a concept that I've learned about in my ExPhys class and apply it so well. For example, I had learned about glucose creating two ATP while glycogen produces three, but I never thought about the importance of taking that knowledge and then making sure your athletes are storing up glycogen.

[@ellieconiaris9073]

This was a great overview of the 3 Energy Systems and how they work together to allow us to produce energy

[@jakebergherm2786]

This was a great review from exercise physiology! I like that it was really easy to follow what you were talking about and built upon what you were talking about.

[@joshwillbanks851]

This reminded me a lot of the content from exercise physiology as well! It was very easy to follow, very helpful!

[@luciavaldez2601]

This video was a great reminder of the energy systems. Being able to correlate them to specific training aspects is something that I hope to learn more about this semester.

[@Chasebowen23]

taking sports nutrition with Dr lynch has helped me learn the basics of this concept.

[@IvyBartlett]

Thank you for the brief reminder of these systems. I've studied them in more detail in other classes, but this refresher helped bring it all back!

[@DevanneyBoyd]

It is super helpful to have a video that breaks down all of the dense content from the text. The visuals are also helpful alongside the explanations.

[@miadenava585]

This video super informative about the three primary energy systems that are used during exercise. Thank you Dr. Goodin for explaining in detail how each system contributes to energy production!

[@jupshaw]

Watching these videos certainly allow me to understand the major concepts of our energy systems as it is a major portion of my exercise physiology class. Great video!

[@cadentomlin2646]

I like how the two classes build off one another

[@mollytucker567]

I have learned about energy systems in many of my classes but I still found this video extremely beneficial as they can be harder concepts to understand that you can always use a refresher!

[@macynunez4455]

I have always had a hard time understanding the intricacies of each energy system even though I have learned them so many times, but this video has really done it for me! Thank you for the clear explanations and good applications that connect your examples to what is actually going on!

[@jadenrea1109]

This video was really helpful in breaking these systems down in a more simple manner. These systems can become complex and difficulty to understand but I felt this video helped break them down into stages where I could understand them more easily.

[@moirabryson5042]

Thanks for the little reminder of these systems. I've learned them more indepth in other classes, but this refresher brought it back!

[@jackstraining]

It’s so cool how we were made with energy systems in place for high intensity exercise. It’s interesting how some energy systems lend themselves to the next one with their byproducts like the Krebs Cycle byproducts going to the ETC.

[@torilucht5871]

This was a great video explaining the different energy systems and I did not totally realize that there was a fast and slow glycolysis. I always thought there was one form of glycolysis so this video really help differentiate between the two. These energy systems are ones I will need to remember for the remainder of my academic career so now I have a better grasp of this concept.

[@kennyvogan5673]

Its very nice to get a semi-short explination on the energy systems after receiving so much information from ex phis!

[@arlenemagana8147]

it definitely helps me break down the readings in this class!

[@lexireynish5892]

There is so much that goes into these topics, so I appreciate how this video laid out all of the information and processes.

[@pedrolunaperfomance]

Thank you Dr. Jacob, your videos have helped me to get back to the field after a few years out. God bless you.

[@joshwillbanks851]

This was a great review of all the energy systems, especially when it comes to how they apply to exercise. Thanks!

[@TreyWeedman]

I agree! I like the graph that he gave about the relationship between the max rate and duration of ATP production of the 3 systems. This helped put them into perspective.

[@mattdkuykendall]

Working on my CSCS exam and your videos are a life saver! Definitely more lucid than the text I'm studying from! Thank you for creating and posting.

[@madelinehernandez8838]

Even though I have learned these systems multiple times, the information gets jumbled together and I forget key components. This was a great reminder of how the body switches through these systems during exercise.

[@JonathanKozasky]

Learning about the body's 3 energy systems was very interesting. I liked the chart at the end breaking down the durations compared to intensity.

[@VirAquinoPLNU]

I remember seeing metabolism in my nutrition class and I felt so intimidated. Now, with all the things I learned from nutrition, sports nutrition, physiology and Exphys, seeing all the words associated with metabolism isn't as scary anymore. Also, this video is a great refresher for the 3 energy system!

[@laurenwahl9715]

Thank you for making energy systems easier to understand! It was a great reminder of the 3 energy systems!

[@kayleebyon2492]

agreed

[@sarahcox-barden]

I love the breakdown in this video! I thin reviewing the systems is extremely helpful for learning how the movements in a weight lifting class are doing their jobs.

[@ZaraHoughton]

I completely agree!

[@matthewwadley4348]

The breakdown and explanation of each energy system was a great learning experience. While I had read about them in the book already, this video helped me understand them more

[@ChynnaKifer]

Thank you for breaking down the glycolysis diagrams! Also, thank for showing what types of events use glycolysis.

[@DerekLinck]

Very informative breakdown of the 3 metabolic energy systems. The diagrams helps alot with understanding the cycles.

[@Adam.gates_]

This was a great breakdown of the energy systems. This is such a large topic, and you've made it as simple as possible to understand. Thank you!

[@joyshang5670]

I did not know about the phosphagen system which is how our body manages short periods of high intensity! Thank you for explaining the different energy systems that our body uses.

[@kayleebyon2492]

I enjoyed learning about the different energy systems as I did not know much about it beforehand

[@dannicazambrano]

This is a super helpful video to understand the energy systems and how they perform in the body!

[@ryanharris8481]

It is very interesting learning about all of the energy systems our body has and when they are actually being used throughout our day/workout.

[@julianasum8481]

This video helped me to better understand the physiology of the three metabolic systems, as well as attributing certain types of exercise to the energy systems.

[@willhopkins4197]

I really appreciate the thorough explanation of each of the energy systems. No matter how many times I go over them in classes, it always feels overwhelming, so it is great to keep reviewing them.

[@ZaraHoughton]

This is so true. There is a lot of information provided and it is easy to forget.

[@saeternj]

Loved the breakdown of the different energy systems and also really enjoyed the key point sections emphasizing the significant information!

[@aliciahernandez00233]

Thank you for this video! I have previously learned about the energy systems in other classes but it was nice to focus on them in terms of exercise.

[@jamarmack9626]

Having the diagrams that showed the entire process of each energy system was really helpful in being able to see where everything was happening.

[@wyattcarlson7504]

This idea of the body having three different energy systems and how each is used has always been an area in the body's physiology that has been a little confusing to me. The video helped to clear up some of the questions that I typically have.

[@abartsch0022]

Wow that was alot but I like how you explain it with a lot of pictures. I also loved the lion sound effect for some humor. Also that is cool how all three systems are all at work o matter what the activity is, it just takes turns on which one is the primary system depending on how long the exercise is and how intense it is. I also liked how you showed how glucose and glycogen can make two different ATP yields since glucose needs a couple to get the ball rolling.

[@cameransherwood5157]

I feel like with your video I am starting to feel more confident in my understanindg of the three energy systems and when each one is being the prime doer!

[@emilywalker9462]

This video was a great refresher/reinforcement from learning energy systems in ex phys last semester. It was super interesting to relate them to various events.

[@bmsith0024]

It's amazing to when I consider how many reactions a molecule of glucose goes through to generate ATP. When I first learned of the coupled reaction, I thought that it was a very inefficient process.

[@Jerel_Q]

I agree! What a complex mechanism!

[@AnnaNovelo]

It's truly amazing! I really am in awe of all that our body is doing all at once every single time we move.

[@avajgallo]

It is so cray how our body works and most of us don't even know it. Thanks for explaining that so well.

[@MaryErickson335]

I learned about this in biology and it is very interesting to connect it to strength training!

[@celinegriffin3244]

This was a great video on breaking down all the energy systems and I liked how detailed the information was. Especially using the charts based on the effect of an event duration and the primary energy system used.

[@KeeganDeBever]

It was interesting to review the different systems that are involved with how the body produces energy. Two things stood out. First, I didn't realize that all of the three different energy systems are working together at different moments, not one system works independently at one time. I also thought it was interesting that you mentioned our body will start to break down protein in certain circumstances if it needs to, which is not ideal.

[@NathanHanson-gt2kq]

It's cool how the body can utilize all three systems in an exercise!

[@drewamato5467]

This was very helpful in getting a deeper understanding of the energy systems. This is the third class this semester where we have covered the energy systems. The other classes didn't go this in depth but I'm glad you did. This lecture feels way more beneficial than the others in the other classes.

[@kylesands9693]

Jeez gave me flashbacks to Fliestra's class Dr. Goodin. Video really cleared up the glycolysis system for me. I didn't know the difference between slow and anaerobic glycolysis until today!

[@aribhalla9820]

It makes so much sense why certain types of exercises are explosive from a physiological standpoint, while others are steady-state and apply to building endurance.

[@BrianaReynoso]

Its really interesting that are body can just switch off into these cycles without us having a clue! These are some pretty hefty cycles, ill definitely be going over it a couple times!

[@jakegonzales1367]

This was a nice review from Ex phys, the glycolytic system is something that is ingrianed in my brain, due to A and P and Ex Phys and now this class.

[@madelinejewelnebril2871]

It's interesting to know that protein can be used as a "backup" in extreme situations. It's so cool how our bodies can adapt in these ways!

[@audreyoates3242]

Understanding the different energy systems and the way they function for different activities is so interesting. The way you explained everything was so helpful as these can be very complex, thank you!

[@MatthewDuPrey325]

I found this video to be very interesting especially how you ended up going into the duration and intensity of different energy systems

[@clairemasterson6031]

I really enjoyed going deeper into the energy systems, It definitely helped to better understand how they each work.

[@evakoutelieris9550]

I really enjoyed this video and how descriptive and broken down the systems were!

[@evaozimec]

Fascinating to learn that the by-products of the CP-system turn on the fast glycolytic system!

[@arieh4212]

Bloopers for the win🙌🏽 Great overview video. Short and informative! 😊

[@cutetwinkie47]

Thank you for this recap! I always forget that ATP is not used solely for exercise, but more importantly basic cellular function. I think it is so neat that our body's are so unique in the way that is it has multiple energy systems for such specific events.

[@kieranmccarty4050]

Thank you, Dr. Goodin! It was a great refresher from exercise physiology. Can’t wait to watch more videos!

[@coreycollier973]

What was most interesting to me from this video was the difference between fast and slow glycolysis and how they each have their own advantages.

[@thedarkestcloud]

I am preparing the NSCA certificate and the book on this chapter is very confusing. Thanks for these videos that go straight to the point !

[@bensonmutuvi8429]

Reviewing the roles of atp and each systems unique roles was very helpful!

[@TRamos-pl6oo]

It is really interesting to me how these 3 systems are constantly working together in the body to allow it to function, even for the simplest and smallest tasks

[@rozalynnlarson8835]

It was helpful to see the relationship between maximum rate of ATP produced and the total ATP that each energy system is capable of producing over time. I was surprised to learn that these two components are inversely related

[@caleighgarcia7792]

This video was a great review of exercise physiology. I also love the bloopers at the end! It reminded me of my time in structural kinesiology and our team videos!

[@emmasanchez5975]

This really helped me understand the three basic energy systems better! I was able to see how during exercise it all switches pretty easily.

[@wyntonbrown9439]

It's pretty cool to see how the body changes between systems while working out

[@thelmasepulveda4481]

I enjoyed the breaking down of all energy systems and I found it interesting how they can happen at the same time. My main takeaway is that the extent of which the systems contributes to ATP production depends primarily on the intensity and duration of activity.

[@tianguyen3897]

I found the law of mass to be super interesting. It is amazing how our bodies are able to control systems in such a way.

[@dimitricarrion6145]

I liked how you mentioned creatine as a supplement and why it is so effective.

[@morganrolleri9198]

Great video! It was a good review of the 3 main energy systems and when they are used.

[@livingston-b]

I love that all of these bioenergetic systems work concurrently but just switch which system is the primary source of energy depending on what the body needs to do. It's also crazy that these are happening whether or not we realize it.

[@kayleebyon2492]

Right?!

[@cjbuenviaje]

It was interesting looking at the energy charts! I just saw them in my Nutrition for Sports Performance class with Dr. Lynch! It’s cool to see how these two classes compliment one another, but one is nutrition and one is strength and conditioning! It also reminds me on my exercise physiology class except!

[@joshcombs123]

Something super interesting to me in the fact that there is two different types of glycolysis, depending on what type of energy is needed.

[@lizetteblackwell3031]

Your videos are incredibly helpful and easy to understand. Thank you!

[@michaelroman4042]

Appreciate all the work you put into these. They've been super helpful!
