Muscle Contraction Explained | Concentric, Isometric, & Eccentric

Exclusive strength and sport science content: / drjacobgoodin
Muscle doesn't just "flex", it contracts in three distinct ways! In this video I will explain muscle contraction at the whole muscle and myofibrillar levels. In short, sarcomeres shorten during a concentric contraction, lengthen under tension during eccentric contraction, and maintain tension without changing length during isometric contraction. This lecture is part of a free, 25-video series covering every facet of structural anatomy. Don’t just memorize human anatomy, master it: bit.ly/38MuIHg

Hey there kinesiology friends! Thanks for checking out this video-it’s part of a playlist that covers every major region of the body: including bony landmarks, joint movements, and muscle actions. You can find that here: bit.ly/38MuIHg
Additionally, check out my Kinesiology Concepts playlist where I spend 5-10 minutes simplifying important kinesiology concepts: bit.ly/3mgKy1K
Or stop by my channel for complete teaching series on strength and conditioning, statistics in kinesiology, and sport science: bit.ly/2Rlg5kQ
Have a great day and remember to move well, live well, and teach others to do the same!

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.
