I thought I knew everything about muscle fiber types and training...maybe not!

I am a huge fan of Dr. Andy Gaplin.  He has his PhD in muscle bioenergetics and runs the "Biochemistry and Molecular Exercise Physiology Laboratory" at CSU Fullerton. He is an unbelievable resource and my "go to guy" for a deeper level of understanding of skeletal muscle, energy systems and how they are affected by training. This video's below cover the most current research on muscle fiber types and how they are affected by training, including the history behind why there is confusion about fiber type changes after training.
