Dr. Jacob Goodin is a professor of kinesiology at Point Loma Nazarene University (PLNU), and holds a PhD in Sport Physiology and Performance from East Tennessee State University. He has over a decade of experience as a strength and conditioning coach and sport scientist from the high school to NCAA Division I levels. In addition to his role as a professor and research mentor, Dr. Goodin directs the Athlete Monitoring Initiative at PLNU, which provides testing and monitoring services to over 200 athletes yearly as well as research opportunities for kinesiology students.

Thanks for providing easy-to-understand videos of complex topics.

[lilyhodgins]

I really like the interaction in the slides, it ends up being much more helpful to me than just a voiceover

[mikestatz]

the images really help to visualize the concepts from the slides

[Henrik-umbe]

You explained the basis of biomechanics WAY better than what my university was supposed to deliver, excellent! I don't know if you deliver biomechanics on specifics movements, but considering the growing interest of handstand in fitness, wellness in general. That could be something worth talking about! ;)

I loved how you drew the axis of rotations right after explaining them. It helped make it clearer and easier to learn! I was a bit confused on how elbow flexion moves through a sagittal plane? I would assume it to be moving through frontal plane. Thanks! -Zaina Daniel

[dimitricarrion]

I liked the free body diagrams that you showed along with you drawing the joints connecting to each other!

[cassandraalviz]

this was a super helpful breakdown! I was getting lost reading about it, but this was great!

[oliviadyck]

Thanks for the review about anatomical terms and planes and position etc. It was a helpful refresher before getting into the tougher content in this course!

[anthonydumas]

Never get tired of seeing that intro lol you got some impressive lifts in there. Also, Loved the examples you gave to help us better understand the concept of Closed Skills and Open Skills. Examples are always the key for things to make sense to me.

[doudouzhang]

Thank you so much, this series help me a lot to learn Biomechanics.

[lisamcabee]

Your videos are super helpful! Thanks for putting them out for all of us to keep learning! :)

[peytonyoshida]

I really appreciated the diagrams and drawings, I have never heard of the different axises of rotation and seeing them on the same diagram as the planes made it way easier to comprehend!

This is great, love the discussion of relative coordinate systems. I would be interested in you discussing some of the more common/important body subsystems relevant to different activities and also sedentary life. For example, I was running and injured my knee. My PT is talking and thinking about the whole system, and maybe nested subsystems? of my body that led to that led to me injuring myself. For example she talked about my posterior chain, and opening my hips up. Other than the posterior chain, what are other interesting and useful subsystems? How can understanding of these sybsystems help one live a healthier sedentary life and exercise holistically at different levels of intensity?

[Yasmin-qewf]

thank you for the clear refresher on the body positions and pov's. I find it more helpful being able to see both 2-D and 3-D cartesian coordinate system.

[alexcarr]

The free-body diagram though simple, can help with a broad understanding of the joints.

Good morning sir very useful video Biomacnics please Gaied all Subjects 1.Sports psychology 2 Health and physical education. 3. History of physical education Video making.

Hi, Dr. JACOB GOODIN, please I can I have some PDF for Biomechanics, Physiology and Anatomy for sport ? I will be very grateful DR.❤❤❤🎉🎉🎉🎉

[eyessee]

Why cant we just say front back side and middle? 😂
