BiaBrain Vol. 1 Issue 9 | Muscle Growth, Caloric Surplus, Training Load, Measure Muscle Size

Welcome to Issue 9 of Bia-Brain, co-authored by Holly T. Baxter and Samuel L. Buckner.

In this issue, we break down a recent 2024 intervention examining muscle growth outcomes in the bicep muscles in response to training at different muscle lengths. Do we really need to include different bicep curl variations in order to maximize muscle growth? Check out what the authors found in this month’s issue!

We also discuss a fascinating 2023 paper that examines the muscle growth responses between groups resistance training and consuming different amounts of calories. How crucial is a caloric surplus for maximizing muscle growth—is it as essential as it's often claimed to be? Gain greater insight in this month’s issue!

We also review the literature used for the suggestion that more fatigue accumulates with low load training compared to high load training. We answer the question– “Should we avoid low load training due to the higher amounts of fatigue produced?”

Finally, how good is DEXA at measuring increases in muscle size? If your muscles have grown over an 8-12 week period, will this be reflected accurately in a DEXA scan? In this month’s issue we break down a paper examining comparing changes between DEXA with the gold standard, MRI. 

Dive into this issue for a comprehensive understanding of these pivotal topics in the fitness and nutrition realm.
