Iron Culture Podcast's video: Ep 229- Is Failure More Important Than Volume For Hypertrophy ft Dr Zourdos Zac Robinson

For more MASS science-based content check out https://massresearchreview.com (en español https://revistamass.com/) In this MASScast episode we’re joined not only by MASScast fellow host Dr. Mike Zourdos, but also PhD candidate Zac Robinson of Data Driven Strength, both of whom are coauthors on a pre-print that is making a lot of waves in the evidence based community. Their series of meta regressions has shown that perhaps the impact of failure is more substantial than previously believed, at least for hypertrophy. But is it that simple? Also, is this paper a “game changer” when it comes to the understanding of how volume and effort relate to hypertrophy? Tune in to find out the details that almost everyone talking about this paper, besides the authors themselves, are getting wrong. 00:00 A breakdown of what you are going to learn… in exactly one minute (and reintroducing the Dr Mike Zourdos and Zac Robinson) 4:38 Introducing the paper and how the data was analysed Robinson 2023 Exploring the Dose-Response Relationship Between Estimated Resistance Training Proximity to Failure, Strength Gain, and Muscle Hypertrophy https://sportrxiv.org/index.php/server/preprint/view/295 Refalo 2023 Influence of Resistance Training Proximity-to-Failure on Skeletal Muscle Hypertrophy: A Systematic Review with Meta-analysis https://pubmed.ncbi.nlm.nih.gov/36334240/ 19:35 Estimating RIR from alternative set structures (cluster and rest redistribution sets) and velocity-based training Carroll 2019 Skeletal Muscle Fiber Adaptations Following Resistance Training Using Repetition Maximums or Relative Intensity https://pubmed.ncbi.nlm.nih.gov/31373325/ Lasevicius 2022 Muscle failure promotes greater muscle hypertrophy in low-load but not in high-load resistance training. https://pubmed.ncbi.nlm.nih.gov/31895290/ 30:05 What surprised Mike about the findings? 39:00 Going in-depth on the meta regression models and how resistance training variables interact with each other Schoenfeld 2017 Dose-response relationship between weekly resistance training volume and increases in muscle mass: A systematic review and meta-analysis https://pubmed.ncbi.nlm.nih.gov/27433992/ Baz-Valle 2022 A Systematic Review of The Effects of Different Resistance Training Volumes on Muscle Hypertrophy https://pubmed.ncbi.nlm.nih.gov/35291645/ 1:00:57 The relationship between volume and hypertrophy 1:15:33 The broader issues with resistance training research 1:34:34 Concluding summary of the paper and where to find our guests Zac Robinson Instagram @zac.datadrivenstrength and @datadrivenstrength Data Driven Strength Podcast https://podcasters.spotify.com/pod/show/datadrivenstrength ResearchGate https://www.researchgate.net/profile/Zac-Robinson-2 Dr Mike Zourdos ResearchGate https://www.researchgate.net/profile/Michael-Zourdos-2
