The Limitation Within Meta Analyses Is the Statistical Power

In this episode we are excited to revisit an ever-controversial topic in bodybuilding, training to failure! Yes, we’ve discussed this before on Iron Culture, and yes, people have surprisingly (but maybe not so much when you dissect it…) strong feelings about training to failure. You may remember that one of the biggest limitations in the literature we previously discussed in our last episode was that there are different ways of defining failure. Should we be lumping together studies that use “momentary muscular failure” with studies that used “repetition maximums” or “voluntary failure”? Probably not. But great news, Martin Refalo a Ph.D. candidate at Deakin University specifically studying the effect of failure on hypertrophy joins us in this episode. Martin recently published a scoping review and a subsequent meta-analysis that specifically identified these differences in failure types and analyzed the literature based on these distinctions, as well as looking at velocity loss thresholds to provide new and important insights on this topic!
