92: Make Dr. Loren Fishman Make Sense

In this episode of the Movement Logic podcast, Laurel and Sarah dissect a recent email they received from Dr. Loren Fishman, in which he expressed frustration over their critique of his study on yoga and bone density.  In this episode, they address Fishman's email and take another look at his study, Twelve-Minute Daily Yoga Regimen Reverses Osteoporotic Bone Loss.  Laurel and Sarah's conversation explores claims made in the email, as well as Fishman's study’s methodology and findings. They compare his claims against established evidence on bone adaptation and emphasize the importance of high-load and high-impact exercise for building bone. They also highlight the need for exercise recommendations to be grounded in solid, evidence-based research—especially for women looking to prevent or reverse osteoporosis and osteopenia.Get on the wait list for our Bone Density Course: Lift for LongevityFollow Movement Logic on Instagram00:00 Introduction00:47 Personal Updates & Course Insights14:25 Critique of Dr. Fishman's Yoga Study52:45 Critique of Yoga's Efficacy in Bone Building53:03 Mechanostat Theory and Bone Adaptation55:18 Challenges in Measuring Yoga's Impact on Bones01:06:17 Dynamic vs. Isometric Contractions in Exercise01:10:20 Unfalsifiable Claims and Scientific Inquiry01:15:16 Turkey Studies and Sustained vs. Intermittent Loading01:18:14 Dynamic Strength Training vs. Impact Training01:18:28 Cellular Accommodation and Running01:19:00 The Importance of Rate of Loading01:21:21 Critique of Yoga for Osteoporosis Claims01:26:24 Red Herrings and False Comparisons01:51:41 Concluding ThoughtsREFERENCESFishman’s StudyThe poses in Fishman’s studyTables of P values and more P values from Fishman’s studyEpisode 79: Make Yoga U Make SenseEpisodes on the Movement Logic podcast 5, 38, 51, 53, 84, and 88 that referenced Fishman’s paper.Episode 56 of the Yoga Research & Beyond podcast that looks at Fishman's paper.LIFTMOR trialLIFTMOR-M trialMedex OP Randomized Controlled TrialMeta-analysis on High-Load Resistance Training (HLRT)Systematic Review on Pilates and YogaBone "mass" and the "mechanostat": a proposal (Frost, 1987)Molecular pathways mediating mechanical signaling in boneEpisode 82: Weird Science1984 and 1985 Turkey Study
