The animation and editing must've taken effort, thank you for taking out the time, this video was very informative

[@HEATHERFIT]

This video did take a very long time to make and it was worth every minute of work! Thank you so much for your comment and I am so glad this video helped you!

[@kelseydaniels2807]

This video helped so much, I had been struggling to get this into my head and this video saved me. Thank you.

[@HEATHERFIT]

Thanks for your comment Kelsey! Before I broke it down like this I always had trouble with it too. I am SO happy this video helped you :) Best of luck to you! If there are other physiology-related videos you'd like to see let me know!

[@manelkapeiris]

Me too
Thank you so much ❤️

This video rocked Heather. I appreciate the lengthy explanation and details you gave on the theory.

[@HEATHERFIT]

Thanks so much Ryan! I am so glad you liked it and I am glad it was helpful :)

[@ymkzyk]

Thank you for simplifying a complex theory. The animations and narration are brilliant.

[@BigFellah]

Great explanation! Very easy to comprehend, thank you!

[@aisham.7406]

Amazing, never been done before, super helpful, love it, appreciate it, like it

[@pamellacampos6777]

This video helped me a lot! Thank you very much, I loved your explanation

[@laurenmyatt105]

I have watched numerous videos trying to understand this and thanks to your video I finally get it! Thank you!!

[@HEATHERFIT]

This makes me so happy to hear! I'm SO glad this video helped you :)

[@nicholasyork2396]

Thank yo uso much for this! These short type videos are the best. I just need to understand some basics for MCAT at times and don't need a 30 minute lecture on it. This was perfect!

[@HEATHERFIT]

I'm so happy this helped you! I found the same thing back when I was studying and this way of learning the Sliding Filament Theory helped me so much. Good luck on the MCAT, you got this!

[@mariageorgiou9410]

Thank you so much Heather for making this video! I have a midterm exam on physiology tomorrow and i was struggling to understand the muscle contraction cycle with my professor's notes. And in only 3 minutes i understood everything! You just got a new subscriber

[@HEATHERFIT]

Aww thank you so much for your kind comment and GOOD LUCK on your exam tomorrow :) Let me know if you want to see other types of videos! I'm a kinesiology graduate so I'm trying to make more videos related to health, wellness and other educational videos. I know the struggle of these types of exams, and love teaching, so let me know if any other videos would be helpful for you :) Thank you for subscribing :)

[@MeilinofTrades]

Thank you very much for this easy explanation! I'm in a PT course and we needed to find a simplified way to explain this BUT I couldn't even understand the process. So after reading my chapter and watching this video it finally made sense. Short and to the point! Thank you! May God Bless you!

[@HEATHERFIT]

I feel you! I did kinesiology for school and had the same problem! Breaking it down this way really helped me understand it. I'm so glad you found this video helpful. Good luck in your PT course :)

[@potatofries549]

I’ve watched too many videos but this one had me understand it more clearly and easily memorize it. Thank you.

[@HEATHERFIT]

yay! I'm so happy this video helped you! :)

[@AboveThaTop]

I agree. Starting with ATP attached actually makes this process much more easier to understand. Thank you

[@Sak__shi]

It was helpful I have shared it with my friends and they find it easy to understand thankyou ❤️❤️

[@Section8dc]

@@HEATHERFIT it went ok, I worked my ass off but I still got about a C+ lol, he still hasn't graded some question so thats about what I think it will be. It was brutal though, like half of it was written questions and I was not prepared for that lol, I had to pull out my creative writing skills to make it sound like I knew what the hell I was talking about lol.

[@HEATHERFIT]

@@Section8dc I can relate to hard tests! That's good you're already at a C+ so far and there are still some other sections to be marked. Best of luck to you!!!!

this one was ideed impressive but i have few questions! 1:45 you said "which causes myosin to forcefully change back to its relaxed shape!" ,Which one is relaxed shape? The one where it lies down on attaching with ATP or this one ,after power stroke? Secondly, can we say energy is expended during power stroke? Which one amongst power stroke and cross bridge formation is passive?
