We are excited to host Dr. Andy Galpin this weekend at our Invictus Fitness – Downtown Location. Dr. Galpin is a Kinesiology Professor at Cal State Fullerton, an expert in muscle physiology and its applications to training, frequent guest on several podcasts including Barbell Shrugged, and a researcher of human performance at the cellular and molecular levels.

Join us Saturday, June 24th from 12 PM – 2 PM
“Genetics vs Training: What Determines Your Performance?”
Invictus Fitness – Downtown

This talk is free and open to the public!

AMPK: The Master Metabolic Regulator that’s Activated by Exercise
Written by Invictus member Dr. Irene Tobias

Have you ever wondered what molecules are involved in your body’s metabolic response to exercise? What turns on the processes of breaking down your energy reserves so you can rapidly fuel your high intensity workouts? What primes your muscles to receive nutrients in the post-workout ‘Window of Gainz’? The molecule known as AMPK is one of your body’s key metabolic regulators and is responsible for all of these activities and much more!

Myosin Heavy Chains and Muscle Fiber Type
Written by Invictus member Dr. Irene Tobias

In Part 1 of this post, we learned how myosin drives the molecular processes of muscle contraction. Now to expand on that knowledge to understand the differences between fast and slow twitch muscle fibers at the molecular level!

What are myosin heavy chains?

The myosin protein complex which forms the molecular motor that drives muscle contraction is composed of four component proteins: two heavy chains and two light chains, twisted around each other.

Muscle Contraction and a Really Cool Protein Called Myosin
Written by Invictus Member Dr. Irene Tobias

Have you ever wondered what powers your muscles at the molecular level and is the source of all voluntary movement and force production in your body? A really cool protein known as myosin ultimately drives all of our power – here is a basic description on how it is thought to work!

What is myosin?

Myosin is one of the most fascinating molecules in our bodies. It’s the protein complex that’s principally responsible for muscle contraction.
