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.
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!
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!
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!
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!
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.
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!
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!
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.
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.
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.
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.
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!
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.
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 :)
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
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.
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.
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!
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.
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!
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!
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.
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.
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.
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.
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.
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.
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.
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.
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.
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!
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.
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!
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
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!
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.
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!
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
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?
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!
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!! 👏👏

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.
Thank you for making energy systems easier to understand! It was a great reminder of the 3 energy systems!
taking sports nutrition with Dr lynch has helped me learn the basics of this concept.
Thank you Dr. Jacob, your videos have helped me to get back to the field after a few years out. God bless you.
Its very nice to get a semi-short explination on the energy systems after receiving so much information from ex phis!
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.
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.
Thanks for the little reminder of these systems. I've learned them more indepth in other classes, but this refresher brought it back!
This is a super helpful video to understand the energy systems and how they perform in the body!

Bloopers for the win🙌🏽
Great overview video. Short and informative! 😊
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.
Thank you, Dr. Goodin! It was a great refresher from exercise physiology. Can’t wait to watch more videos!
I learned about this in biology and it is very interesting to connect it to strength training!
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.

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!
It is impressive to know our bodies know when, where , and how to regulate theses energy systems. Everything comes down to ATP production!
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.
It is so cray how our body works and most of us don't even know it. Thanks for explaining that so well.

Having the diagrams that showed the entire process of each energy system was really helpful in being able to see where everything was happening.
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.
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.
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.
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.
This guy is a legend.
Fascinating to learn that the by-products of the CP-system turn on the fast glycolytic system!
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!
Thanks so so much for this video, extremely grateful!
This really helped me understand the three basic energy systems better! I was able to see how during exercise it all switches pretty easily.
Reviewing the roles of atp and each systems unique roles was very helpful!
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!
Your videos are incredibly helpful and easy to understand. Thank you!
It is so interesting to me to learn how the body adapts to exercise utilizing the different energy systems. Pretty powerful!
Great video! It was a good review of the 3 main energy systems and when they are used.
It's pretty cool to see how the body changes between systems while working out
Appreciate all the work you put into these. They've been super helpful!
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.
I liked how you mentioned creatine as a supplement and why it is so effective.
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.

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

Yet anthor quality video🙌🏽🙌🏽
These are amazing! Thank you!
Something super interesting to me in the fact that there is two different types of glycolysis, depending on what type of energy is needed.
really well explained. thank you!

Thank you for making the video
Very helpful, thanks
I find it very interesting how all 3 energy systems are used at any given time even though one may be doing more work than the others.
It was interesting when you pointed out how our diet can contribute to our oxidative system
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!

thanks and congrats again for the video!! 👏👏
The energy systems are always something that's been a little hard for me to understand but this was a great explanation
Thank you sir
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.
