However, not all athletes benefit as performance changes vary from a 10% drawback to a 14% improvement. The main beneficiaries from such technologies, world-class athletes, have only been analyzed using race times. Objective The aim of this study was to measure running economy on a laboratory treadmill in advanced footwear technology compared to a traditional racing flat in world-class Kenyan (mean half-marathon time: 59:30 min:s) versus European amateur runners. Methods Seven world-class Kenyan and seven amateur European male runners completed a maximal oxygen uptake assessment and submaximal steady-state running economy trials in three different models of advanced footwear technology and a racing flat. To confirm our results and better understand the overall effect of new technology in running shoes, we conducted a systematic search and meta-analysis. Results Laboratory results revealed large variability in both world-class Kenyan road runners, which ranged from a 11.3% drawback to a 11.4% benefit, and amateur Europeans, which ranged from a 9.7% benefit to a 1.1% drawback in running economy of advanced footwear technology compared to a flat. The post-hoc meta-analysis revealed an overall significant medium benefit of advanced footwear technology on running economy compared with traditional flats. Conclusions Variability of advanced footwear technology performance appears in both world-class and amateur runners, suggesting further testing should examine such variability to ensure validity of results and explain the cause as a more personalized approach to shoe selection might be necessary for optimal benefit. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 9.3 2023 SPORT SCIENCES 3 / 127 = 0.024 2023 Q1 T1 3.492 2023 Medicine (miscellaneous) 2023 Q1 Sports Science 2023 Q1 Physical Therapy, Sports Therapy and Rehabilitation 2023 Q1 Orthopedics and Sports Medicine 2023 Q1 18.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Muñiz-Pardos, Borja Universidad de Zaragoza (orcid)0000-0002-9191-9033 Wackerhage, Henning Schönfelder, Martin Guppy, Fergus Pitsiladis, Yannis Ruiz, Daniel 1006 245 Universidad de Zaragoza Dpto.
