This clip is from episode 239 ‒ The science of strength, muscle, and training for longevity with Andy Galpin, Ph.D. Andy Galpin is a professor of Kinesiology at California State University at Fullerton, where he studies muscle adaptation and applies his research to work with professional athletes.
In this clip, we discuss:
- Is there a force difference between fast and slow-twitch muscle fibers or just velocity difference?
- Deep dive into what happens during a muscle contraction
- How muscle fibers of animals differ from those of humans
- And more

I love listening to Dr Galpin discuss physiology.

[@acornsucks2111]

Why?

[@MrOrthodox13]

Muscle contraction 101, and then some, love Andy Galpin.

[@zartic4life]

Well this explains my insane reflexes and why I was always naturally stronger than people my size. Super educational thank you.

[@SuperDodoe]

Pete's a fan of senna's if anyone hasnt figured it out

[@Eysc]

I've learned so much from Dr Galpin

[@acornsucks2111]

Like what?

[@ash.toronto31]

I wish professors in medical schools explained concepts like this.
Only if i had seen this video 5-6 years ago, i would have never struggled in high school, bachelors, and in medical school 😂😂

[@jesseshaver2262]

You should have Scott Johnston on from Uphill Athlete! Has some great lectures on zone 2 and endurance

[@justinklenk]

I learned things about contractile function and physiology, in watching this, that I've been wondering about since 1991 - thanks for posting. 👍❤

[@berner]

So basically 2X and 2A are best for Olympic lifting?

[@stretch1807]

So I CAN become as strong as an Asgardian with plenty of the right kind of muscle fiber!

[@shannonschleifer8602]

13 minute phys!

[@jCommon2333]

Im super into my fitness but this type of talk is so amazingly boring. Nobody needs that much detail. Just tell us what workout is best for fast twitch and slow twitch. And why ne need both. These you tube gurus do this all the time.

[@erickmacias5153]

There are a million videos talking about that, the truth: nobody knows, we have informed guesses about training strategies, this kind of conversation is needed to understand the processes in our muscles.
