Partial ROM Training for Strength, and Protein Requirements for Muscle Growth
The Stronger By Science Podcast
Is Peer Review a Wrong Process?
The peer-reviewed literature suggests that peer review is pretty not great. It does not live up to the kind of agreed-upon expectations in terms of quality and rigor. And it doesn't really provide the level of Quality control that a lot of people are indicating in this conversation. But there was basically an article called Scientific autonomy public accountability and the rise of peer review in the Cold War United States by Melinda Baldwin.
Today’s episode begins with a discussion about an ambitious experiment in the world of academic publishing, and the real-world costs of striving for bench press excellence. After that, Greg presents a segment about partial range-of-motion (ROM) training for strength outcomes. Greg digs into the available research about whether or not partial reps can be used to facilitate greater strength gains, and provides practical recommendations about when and how to incorporate this style of training. That’s followed by Eric’s segment that tackles a fairly widespread misconception about protein requirements for muscle growth. Many people believe that 1.6 g/kg/day is a very clear minimum requirement for supporting hypertrophy, and that falling a little bit short of this target severely limits muscle growth. However, the data suggest otherwise. He explores the available research and discusses some protein target recommendations for people who are prioritizing muscle growth or retention.
