Partial ROM Training for Strength, and Protein Requirements for Muscle Growth
The Stronger By Science Podcast
Do I Need Full Range of Motion Training for Knee Extensions?
The padrosa study was looking at knee extensions. I don't think anyone gets like that Oh shit feeling you get for a one ret max squat when you Feel a really heavy load against your ankle for knee extensions, he says. "It's interesting but uh I'm not like 100 percent sold on it yet" But board press pin press and rack pulls might make a ton of sense to add in Independent of just the general the generalized effects of combining range as a motion.
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.
