Weighted vests are a common intervention used by both coaches and athletes, yet the existing research on weighted vests is virtually nonexistent. In this episode we discuss his pioneering study on weighted vests and their potential training applications for running and hiking. Episode highlights:(16:41) Research design: incremental speed and gradient test, 5-10% body weight vests represent in-race loads(21:26) Stride length and stride frequency: both increase with speed, both variables were unchanged with weighted vests, individual preferred stride frequency and stride length(29:08) Weighted vests for running economy: example ways to train leg stiffness, weighted vests training leg stiffness with greater specificity to running, ~5% bw is reasonable, application across a range of running velocitiesAdditional resources:Training Specificity in Trail Running: A Single-Arm Trial on the Influence of Weighted Vest on Power and Kinematics in Trained Trail RunnersSUBSCRIBE to Research Essentials for UltrarunningBuy Training Essentials for Ultrarunning on Amazon or AudibleInformation on coaching-https://www.trainright.comKoop’s Social MediaTwitter/Instagram- @jasonkoop
