Meet Dr. Michael Roberts, a trailblazer in the world of muscle growth research. This episode promises to be an intriguing journey through the world of scientific research.
Timeline
2:35 – The evolution of how Mike Roberts’ lab did the squat vs. hip thrust study.
5:17 – There is a crazy amount of work involved in a training study.
6:15 – It took about 2 years to pull it off.
8:17 – Animal models – applies to humans? Yes or no?
9:10 – Animal work in nutrition – should we dismiss it?
9:40 – Mike’s take on the value of animal models – specifically skeletal muscle
10:52 – Mike likes the animal models of skeletal muscle hypertrophy
15:05 – CLA works in rodents; doesn’t do shit in humans
16:02 – Do humans undergo skeletal muscle fiber hyperplasia vis a vis weight training?
24:05 – Primary drivers of skeletal muscle hypertrophy in humans
28:45 – Sarcoplasmic hypertrophy – real or fake?
34:34 – The concept of a critical cell size
35:29 – Satellite cell proliferation fuse with existing fibers – so fiber number should go down?
38:00 – Direct fiber counts with splitting – see this paper - https://journals.lww.com/acsm-msse/Abstract/1994/08000/Muscle_fiber_splitting_in_stretch_enlarged_avian.7.aspx
39:52 - Fiber number differs in the same muscle; that is, proximal, middle, and distal.
40:18 – Biopsy data doesn’t reconcile with whole-muscle measures of muscle growth.
44:44 – Do you need to damage muscle fibers or be sore to produce muscle fiber hypertrophy?
48:49 – Responders vs. Non-Responders vis a vis hypertrophy
