Bioenergetics of Training: 3 Energy Systems | CSCS Chapter 3

[@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!

[@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.

[@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

[@dannicazambrano]

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

[@saeternj]

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

[@ClaireStone-jq4wg]

It is interesting to see how all three energy systems interact and pick up where the other leaves off, yet there is never one system working alone.

[@kieranmccarty4050]

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

[@alannabergherm8046]

I thought it was interesting how the metabolism of fat, protein, and carbs led to all of them being reduced into acetyl Co-A to be able to enter the Kreb's cycle. also, i always love a good blooper moment :)

[@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!

[@mikestatz5098]

Coaches always made me run after pitching to try and get the "lactic acid buildup" out of my arm, buncha fakes!

[@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!

[@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.

[@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.

[@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!

[@bilalshaikh6734]

Thanks so so much for this video, extremely grateful!

[@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.

[@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.

[@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.

[@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!

[@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.

[@jackmalone5800]

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.

[@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!

[@ScottMammel]

This was a very helpful breakdown of the energy systems. The only thing that confused me was how the textbook says a net ATP production of 38 ATP (blood glucose) or 39 ATP (muscle glycogen) is produced from oxidative phosphorylation and in the video you say its a net of 36 ATP. What am I misunderstanding? Thanks in advance for your help.

[@rickycarfan54]

that is a wondreful video!!! you make it so clear. I would have a question then… how can we perform at our best in an anaerobic training (kind of lifting weights) of we are on a low carb diet? it that possible? there’s a way in which the body can utilize fat in an anaerobic pathway?? thanks and congrats again for the video!! 👏👏

[@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!

[@karatemplin]

My question would be would an athlete with diabetes have any of these systems altered or would they function differently?

[@ellieconiaris9073]

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

[@Chasebowen23]

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

[@laurenwahl9715]

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

[@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!

[@makennakaczmarczyk7563]

This video helped me better understand the 3 different energy systems! It will be beneficial to know for this class, my other kin classes, and outside in the real world.

[@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

[@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.

[@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.

[@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.

[@jakegellatly8261]

It was crazy to learn that the body produces 36 ATP molecules from a single glucose molecule!

[@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.

[@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 !

[@MatthewDuPrey325]

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

[@braedenmoore3743]

I thought it was interesting how the creatine phosphate energy system is used with any sudden movement or burst of energy from standing up suddenly to running a hundred meter dash.

[@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.

[@evakoutelieris9550]

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

[@austiniturbe4495]

So I don't need to keep a Glycolysis chart for my next basketball practice?

[@melanieweirich8482]

The energy systems are always something that's been a little hard for me to understand but this was a great explanation

[@zoiezantua7002]

It was interesting when you pointed out how our diet can contribute to our oxidative system

[@morganrolleri9198]

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

[@tejasingh6598]

According to Essentials of Strength Training and Conditioning (4th Edition): The oxidative system, beginning with glycolysis and including the Krebs cycle and ETC, results in the production of approximately 38 ATP from the degradation of one molecule of blood glucose. However, if the initiation of glycolysis is muscle glycogen, the net ATP production is 39.

[@James-zm6zj]

I was looking for this comment so I wasn't going crazy. This is what I remember reading the chapter as well.

[@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.

[@haohao2644]

Thank you for making the video

[@sarathrajendran6716]

Yet anthor quality video🙌🏽🙌🏽

[@campbells20042003]

So is the Cori Cycle only used during fast glycolysis?

[@SportifyTVofficial]

so i have 2 questions: 1) If the fatty acids enter directly the krebs cycle couldn't we say that they are more efficient than carbohydrates in giving us energy more quickly? 2) Sometimes i train superset of pull ups and push ups that takes longer than 3 minutes, thus i use the oxidative system. So that means that i train more towards muscular endurance than hypertrophy?

[@bojak76]

Lol I wish my clean and jerk was under 6 seconds :(

[@lucamarin8565]

To this day I still mix up catabolism and anabolism

[@h.f.p.istrengthcoach8918]

hi sir thank you very much for your great explanation. can you tell me how to find biomechanics for resistance exercise. main exercise. like squat bench press lat pull down etc. want to know how many degree of joint etc

[@DrJacobGoodin]

Lot's of videos out there on KZbin for that if you learn primarily through video (I have a few on my channel as well). However, my biggest recommendation is to purchase a biomechanics textbook, or a resistance training textbook. This will summarize research in an easy to understand way and be comprehensive enough to cover all the topics within that realm

[@RakeshKumar-jv6jk]

Can i know the music which is played at last

[@michaelyoung6837]

I c there is an app supplement is that any good

[@ajaynangalia334]

really well explained. thank you!

[@LauraPatterson-hm4hx]

what kind of ipad do you use for your work?

[@ZacharyAird]

I’m currently studying and just graduated from an NAIA called Ottawa. Needed to say this because your thumbnail shows a “Westmont” jersey which is part of the GSAC conference. Just thought I should point that out!

[@DrJacobGoodin]

Love that! Yes, Westmont is where I competed in XC and the mile, where I met my wonderful wife, and where I discovered my passion for kinesiology. Although the NAIA is dwindling, I'm glad to have competed in it.

[@ZacharyAird]

@@DrJacobGoodin That’s great! When playing away games at Westmont, it was indeed a very nice campus!

[@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.

[@markbisnauth3369]

These are amazing! Thank you!

[@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 :)

[@pedrolunatvz]

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

[@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.

[@sawayp4031]

Very helpful, thanks

[@DerekLinck]

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

[@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!

[@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.

[@hannahb872]

It is impressive to know our bodies know when, where , and how to regulate theses energy systems. Everything comes down to ATP production!

[@pranavsasidharan1252]

11:06 , was that an actual roar? xD

[@SuperTroyAustin]

How does the body know when to switch from phosphagen to glycolysis?

[@DrJacobGoodin]

Good Q Troy. It's regulated at a few different levels by a few different things: concentration of glucose in the blood, relative concentration of critical enzymes, competition for the intermediate products of glycolysis and the levels of certain hormones in the bloodstream. More on that here: education.seattlepi.com/glycolysis-regulated-4682.html

[@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.

[@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.

[@ChynnaKifer]

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

[@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.

[@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!

[@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.

[@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.

[@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.

[@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.

[@milandiklic1080]

just watched the video !

[@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

[@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!

[@moirabryson5042]

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

[@joshuawada8783]

I think it was really interesting that there was an INVERSE relationship between ATP production rate and total amount of ATP it is capable of producing over time.

[@evaozimec]

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

[@oliviadyck510]

The energy systems are the most confusing things I have learned so far in undergrad. I have been avoiding it, but I feel like I should just suck it up and memorize every tiny step of glycolysis at this point along with all the names of all the chemicals within it since glycolysis keeps coming up in all my classes!

[@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!

[@arieh4212]

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

[@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.

[@avajgallo]

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

[@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!

[@keonihughes4242]

One thing that stood out to me that I want to remember is the inverse relationship between production rate of ATP and duration of exercise.

[@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.

[@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

[@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.

[@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!

[@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.
