Hormone-Muscle Interactions | CSCS Chapter 4

In this video I will provide you with an overview of the different ways that hormones can interact with muscle cells. We'll also look at different categories of hormones and discuss their responses to exercise. This information comes from chapter 4 of Essentials of Strength Training and Conditioning, published by the NSCA.

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

[Moniiiqueee]

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!

[miadenava]

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.

[mollytucker]

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

[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!!

[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!

[moirabryson]

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!

[NoelleDarquea]

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

[kelli-lynroche]

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

[ryanharris]

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

[macynunez]

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!

[jupshaw]

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

[theroadvikings]

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!

[abartsch]

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.

[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!

[willhopkins]

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

[kylesands]

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

[emilywalker]

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

[morganrolleri]

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

[charmenatchison]

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.
