Nov 23, 2024 Unusual warm weather opens a discussion on climate change, leading to skepticism about the mTOR pathways in muscle growth, branded a 'nothing burger.' The hosts challenge bulking myths, emphasizing smarter dietary and training strategies. They delve into the deceptive nature of social media in fitness portrayals, illustrating the need for skepticism. Individual physiological responses to exercise are crucial, focusing on custom training and understanding muscle fiber types. Finally, they caution against relying on anecdotal evidence, stressing the importance of scientific principles in fitness.

mTOR Signaling Misinterpretation
- People are misinterpreting mTOR signaling and muscle protein synthesis rate elevations.
- Higher mTOR signaling after eccentric workouts doesn't necessarily mean they're better for hypertrophy.
Muscle Protein Synthesis vs. Myofibrillar Protein Synthesis
- Muscle protein synthesis and myofibrillar protein synthesis are distinct processes.
- They can have different timelines and contribute to different adaptations.
mTOR's Role in Muscle Growth
- The mTOR pathway communicates mechanical signals to muscle protein synthesis processes.
- Elevated mTOR markers indicate signal communication, but don't guarantee muscle growth.
