Hormone-Muscle Interactions | CSCS Chapter 4

[@mollytucker567]

I never really thought about exactly how hormones are active during exercise before watching this video. This video was really interesting!

[@abartsch0022]

that is so cool how there is so much going into exercise that is traditionally ignored. I love how you bring in examples like how testosterone interacts with the body to show us that point.

[@Moniiiqueee824]

I often heard about the lock and key theory, but this video really deepened my understanding and made the concept much clearer. It broke down the details in a way that was easy to grasp! Thanks Dr.Goodin!

[@MatthewDuPrey325]

I really found that learning about all of the different categories of hormones was very interesting and very helpful to me as well.

[@AnujThePhysicalEducator]

I feel so blessed to find a channel like this.. I am studying for CSCS and your videos helping me a lot in preparation. Thanks a tons!!

[@miadenava585]

The different categories of hormones are fascinating to learn about. Thank you for explaining in detail how hormones play an important role in response to resistance training.

[@NoelleDarquea]

I loved learning about all the different categories of hormones an how they come together and are intertwined with one another

[@moirabryson5042]

It's really cool to know that our hormones work like a lock and key system with the receptors and the hormones themselves. Thank you!

[@kelli-lynroche8446]

I had not really thought about how great of an effect hormones have on exercise! This video was super insightful and helpful!

[@ameliabrock]

I really liked the emphasis on practical applications for future strength coaches and trainers. Its far easier to develop interest in things when we can see that they're relevant to the real world!

[@laurenwahl9715]

I appreciated how you explained the lock and key theory. It is not as simple as a one to one correspondence, which sometimes would confuse me previously.

[@ClaireStone-jq4wg]

I had no idea how training affects the release of hormones before, during, and after exercise. This was really interesting to learn about and see what contributes to the changes in blood concentrations.

[@everoche3754]

I love learning about how these hormones are active during exercise and what they can inhibit or contribute to.

[@theroadvikings4727]

Just wonderful content. I'm a DPT just now getting my CSCS and love the organization and clarity of the material presented on this channel. Keep up the great work!

[@DrJacobGoodin]

Wow thank you so much for the kind feedback! It definitely means a lot to me that I'm able to impact in-the-trench coaches and clinicians like yourself in some small way. Keep doing your good work helping folks to move well!

[@ryanharris8481]

I found this video very helpful in explaining the different categories of hormones. Understanding the categories helps me understand the hormones

[@rozalynnlarson8835]

I liked learning about the lock and key theory, this was a new concept to me. It's crazy to think that there's always so much going on in our bodies to keep us functioning.

[@jupshaw]

Love learning about how the training stimuli we impose as strength coaches truly affect the human body, great info!

[@morganrolleri9198]

This video was so helpful in explaining how hormones interact with muscles and exercise!

[@dereklinck2672]

really good overview of the hormonal responses based on different resistance-based exercises. and the mechanisms of release were really helpful in understanding.

[@dannicazambrano]

The lock-and-key theory was described really well in terms of hormones being a key and having the ability to have an effect on the cell as long as it fits into the receptor (the lock).

[@kylesands9693]

Had no idea that training would effect hormones so much! Great video as usual.

[@charmenatchison854]

This was really good to explain how the differences in each person affect the productivity of hormonal activity. How you can have the same amount of a particular hormone as someone else but have different outcomes. For instance, dehydration can cause differences.

[@macynunez4455]

I really liked your explanation of the lock-and-key theory because it totally makes sense and it provides a clear way to understand how hormones and receptors interact with each other! I'm eager to learn about how we can program our workouts to leverage our hormonal response to exercise!

[@willhopkins4197]

This was a super helpful summary and introduction video to hormones. It didn't feel super overwhelming and I got a great general idea.

[@lexireynish5892]

I had no idea that our hormones are so linked to our muscle growth. It's such an interesting thing to consider when putting together a workout.

[@kieranmccarty4050]

It is interesting to see how resistance training can have such an effect on how much hormone is produced. Thank you Dr. Goodin!

[@madelinehernandez8838]

There are so many different hormones! It is so interesting to learn how they work in our bodies, especially during exercise.

[@karatemplin]

Thank you for always beginning with definitions!

[@zoiezantua7002]

thank you for sharing the correlation between the intensity of training & hormonal behavior

[@AylethLizarraga]

I think that while there is a lot to consider while being physically active, hormones don't get enough time of the day to be talked about and its clearly a very important topic. This video was a great introduction to some important hormones

[@DevanneyBoyd]

This was a helpful overview of how hormones can interact with muscle cells. The lock and key system is interesting, too.

[@KristinaGreenwood]

Thank you so much for all your CSCS related videos. As a Nutritional Therapy Practitoner who has personally struggled with hormone issues I've spent a lot of time trying to understand the endocrine system. You are an excellent, thoughtful teacher. Your explanation of the ES and hormones is clear and concise. Following the CSCS I plan to work predominantly with women and I hope to make understanding female hormones and fitness digestible for my future clients. Thank you for your videos!

[@emilywalker9462]

Thank you for the refresher! This was helpful especially with the various categories. I find this area to be so fascinating, thank you!

[@wyntonbrown9439]

Really loved that you touched on the circadian pattern. I learned a little about this from one of my previous strength coaches and was really fascinated on how the body functions this way.

[@__luciavaldez]

This video was super helpful tool to go over how hormones can interact with various muscles within our body. I also thought it was super interesting how important it is to consider our hormones when planning a workout.

[@myawilliams8357]

I like how you compared it to a lock and key mechanism. Makes it easier to remember what it is and does.

[@madelinejewelnebril2871]

The lock-and-key theory and how it explains the interaction between receptors and hormones was an interesting part of this video.

[@bensonmutuvi8429]

The fact that by having a good healthy lifestyle that your hormones can be and will be better is awesome.

[@emilydonahue8216]

It’s so cool how interconnected hormones are to exercise! It’s wild how many levels and connections the body has

[@Chasebowen23]

Great explanation of how we use hormones for exercise

[@ellieconiaris9073]

This was super helpful hormones are kind of a daunting concept for me so this video was super helpful!

[@matthewwadley4348]

The hormonal changes in peripheral blood and how the mechanisms that contribute to those changes were fascinating

[@jadenrea1109]

It is so interesting to think that all these mechanism are happening in the body based upon what activities we put out bodies through. I think the Circadian Rhythm is super interesting, and the different theories about when to workout based on the Circadian Rhythm.

[@aliciahernandez00233]

Hormones play such a big role in the body. They can have adverse effects if they are too high or low. It always intrigues me how hormones interact with muscle tissues.

[@jakegonzales1367]

Learnign about Steroid Hormones interactions found to be really interesting. The diagram made it easier to understand.

[@vanessaviramontesPLNU]

Dr. Goodin, the most interesting thing I learned in this video was that hormones have an interaction with the protein synthesis or degradation of muscle adaptations to resistance training. I learned that there are three different kinds of hormones: amine hormone interactions, polypeptide hormone interactions, and steroid hormone interactions. I learned that testosterone can be categorized as testosterone for skeletal muscle and dihydrotestosterone for sex-linked tissues.

[@cameransherwood5157]

Super cool to learn how depending on the force produced in active muscle fibers, we get different amounts of hormones stimulated to release causing muscle growth and inc in strength!

[@emmasanchez5975]

I didn't realize how complex hormones were! It's also interesting that there are peak times with testosterone and one being in the morning is actually really interesting.

[@joyshang5670]

Hello! I really liked hwo you explained the lock and key system in the body because I did not know about that before!

[@sarahcox-barden]

it's interesting to learn about how the hormones are linked to what happens during exercise. it would be interesting to learn about this outside of resistance training

[@VirAquinoPLNU]

This is such a great refresher to the endocrine system but with response to training. Im curious to see what kind of programs of exercises can promote the increase/decrease of these hormones

[@isabellecousineau302]

I think the lock and key theory explains a lot how receptors/hormones work in correlation with exercise which is very interesting to learn about.

[@wyattcarlson7504]

It was very interesting for me to learn about how the resistance training affected the hormones that are present in our bodies. For example, when you talked about how heavy resistance exercise sessions can increase the number of androgen receptors in the body.

[@ChynnaKifer]

Hi! I think it was very interesting when you said that testosterone can peak more if one works out in the morning than in the evening! Thank you!

[@nishajaisingh2745]

Your videos are really helpful Sir. Thank you for doing this

[@DrJacobGoodin]

It's my pleasure Nisha. Thanks for watching!

[@thelmasepulveda4481]

It was interesting to know that hormones are secreted before, during and after exercise because of the stress of resistance exercise!

[@clairemasterson6031]

The changes in concentrations was really interesting to me.

[@torilucht5871]

I am always surprised by how many hormones there are in the body and it is cool to see the role of each one. it is also cool to know that the way we train can determine the type of hormones that are involved. Very interesting!

[@alexdavidson294]

i liked the input about how testosterone is present like in the mornings so you can utilize that time to train better !!

[@joshcombs123]

I find it so interesting how just one or two training sessions can have the ability to up regulate receptors.

[@saeternj]

Amazing how hormones can go through adaptation and can be adjusted via training regimen!

[@jackmalone5800]

The idea of a lock and key with hormones is really interesting that certain hormones just can’t bind with certain cells, but it does make sense.

[@caleighgarcia7792]

I think it is super interesting that even though we could have more of a hormone concentration, this does not mean that we necessarily have more effect of the hormone, only higher potential.

[@tianguyen3897]

It was interesting to learn about the different categories of hormones and see how each of them varies based on its characteristics and mechanisms!

[@braedenmoore3743]

I had no idea about the complexity of hormone-muscle interactions. I thought it was interesting how the way that our bodies respond hormonally to exercise is directly linked to the way we program that specific exercise.

[@JonathanKozasky]

The idea of testosterone reaching its peak in the morning and the potential benefits of training during this time is something I never thought of and is very interesting.

[@BrianaReynoso]

I never knew how important it was to consider our hormones when planning a workout.

[@julianasum8481]

It was interesting to see how impactful hormone responses are, based off of the specifications of a resistance training protocol.

[@cutetwinkie47]

Hormones are an interesting topic to learn about! I didn't realize that it only took about 2 resistance training sessions to increase the number of androgen receptors in the muscle.

[@coreycollier973]

It is interesting to hear the idea of testosterone peaking in the morning and how that might be an advantageous time to train.

[@evaozimec]

I found it interesting that the specific force produced in activated fibers during resistance training can stimulate receptors for anabolic changes.

[@alannabergherm8046]

I thought it was interesting to see how peripheral blood can effect so much when the concentrations of hormones changes!

[@dimitricarrion6145]

I found it interesting that having more testosterone doesn't mean it is all being used up when you mentioned that it needs to bind to a receptor to actually be used.

[@avajgallo]

I never knew that your hormones get more diluted when you drink water. Very interesting!!

[@celinegriffin3244]

It was interesting to learn about how our hormones get more diluted when we drink more water!

[@cjbuenviaje]

I think it’s interesting how even if you aren’t a completely trained athlete, a small workout session can lead you to upregulate your hormone levels 10:41.

[@thomaskinzler]

It is a completely new idea to me to consider how hormones are affected by training. I had heard about testosterone spiking in the morning but I didn't know if that was true or not. I wonder if there has been any research in the last few years that looks at training right after waking up versus later in the day.

[@hannahb872]

I didn't know for guys that they have peak levels of testosterone during the day, but the makes sense since the morning is when the body is waking up and prepping for the day.

[@brysonhashimoto2878]

I find it very interesting that in guys, testosterone has a high conentration in morning and can be a reason why one should workout in the morning. I like to workout in the morning because I feel like I have more energy, which relates to how testosterone peaks in the morning.

[@makennakaczmarczyk7563]

I think it's really interesting how the number of androgen receptors can increase with just a few heavy resistance trainings!

[@Adam.gates_]

Since polypeptide hormones require a secondary messenger, does it take longer for their effects to take place compared to fat soluble steroids?

[@chrismangram8463]

It is that heavy resistance exercise can increase the amount of receptors on muscles.

[@bojak76]

How crippling is the stress caused by an upcoming meet or competition on the athletes hormones and training? If stress induces sorts of hormones that can cause fatigue without training, how do we help an athlete that has problems with high stress in competition?

[@DrJacobGoodin]

Super good question Amanda. It depends entirely on how the athlete is equipped to deal with stress and anxiety and a host of other psychological factors. One of my grad students is actually investigating how athletes handle stress and anxiety right now, and one of the best ways to do this as a coach is to engage in an ongoing athlete monitoring program that tracks such things. The DASS 21 questionnaire is a good place to start. Also, head to chapter 8 in the textbook if you're interested in sport psych

[@oliviadyck510]

Is tryptophan that one hormone that everyone complains about on Thanksgiving? Is that just a wives tale or is it actually in turkey and does it actually make you tired?

[@DrJacobGoodin]

Tryptophan is the real deal, no wives tales! See here: www.ncbi.nlm.nih.gov/pmc/articles/PMC7325545/

[@aribhalla9820]

It's crazy how just 1-2 lifting sessions a week can increase the up-regulation of testosterone.

[@melanieweirich8482]

I always knew hormones were important for reproductive health. I never realized that extended to exercise health.

[@joshuawada8783]

SCIENCE! I had to quickly look it up for myself, but serotonin, as mentioned at 9:24, is usually for temporary moments of anxiety or fight-or-flight-like responses. increased levels of serotonin can lead to excessive nerve cell activation. Which can result in the body beginning to ignore these signals (akin to ringing in your ears becoming tuned out as your brain adapts to the sound) or too much stress being put on the target tissue or muscle and causing lasting damage.

[@DrJacobGoodin]

Nice! Great explanation Josh.

[@lucamarin8565]

I feel like you always hear about steroids and their effects but never the science behind it. Its good to dive in behind the scenes and learn the physiology

[@mikestatz5098]

I did not know there may be a benefit to working out in the morning because there is a boost in testosterone.

[@shubhamrahangdale7713]

Pls elaborate Tissue clearance Rate

[@SuperTroyAustin]

how bad would it be for the body to receive more hormones in a very illegal way?

[@DrJacobGoodin]

Depends, if this someone was under the guidance of a qualified physician, getting bloodwork done every few months, and getting their gear from reputable and 3rd-party tested sources then it would be within the realm of what I considered "safe". But it's tough to have all three of those caveats met if the use is still illegal... Not condoning it, but I think it can be done in a safe (albeit illegal and therefore unethical) manner.

[@jakegellatly8261]

It was shocking to learn that as little as one or two heavy resistance exercise sessions can increase the number of androgen receptors in the muscle!

[@austiniturbe4495]

All of a sudden I wanna play basketball early in the morning 🤔
