Altitude alters the effects of a power-oriented resistance training on the force-velocity relationship of elite judokas De Sousa Fernandes Alcobia de Almeida, Filipa Bonitch Góngora, Juan Germán Feriche Fernández-Castanys, María Belén Schoenfeld, Brad J. de la Fuente, Blanca Padial Puche, Paulino Judo Hypoxia This study investigated the effects of a 3-week power-oriented resistance training program performed at moderate altitude on the lower-limb maximal theoretical power and force-velocity (F-V) imbalance of elite judokas. Twenty-two elite male judokas were randomly assigned to either a hypobaric hypoxia or normoxia group. Mechanical outputs from an incremental loaded countermovement jump test were assessed at sea level, before and after training, and 1 week later. Results indicated an increase in the maximal theoretical force and a reduction in the F-V imbalance both at moderate altitude and sea level. Altitude training induced additional benefits when compared to sea level for F-V imbalance (8.4%; CI: 0.3, 17.3%), maximal theoretical power (2.09 W·kg-1; CI: 0.13, 4.52 W·kg-1) and force (1.32 N·kg-1; CI: -0.12, 2.96 N·kg-1), jump height (3.24 cm; CI: 2.02, 4.80 cm) and optimal maximal theoretical force (1.61 N·kg-1; CI: 0.06, 3.60 N·kg-1) and velocity (0.08 m·s-1; CI: 0.00, 0.17 m·s-1) after the training period. The hypoxia group achieved their best results immediately after the training period, while the normoxia group achieved them one week later. These results suggest that a power-oriented resistance training program carried out at moderate altitude accelerates and improves the gains in leg push capacity while minimizing lower-limb imbalances. Therefore, it seems appropriate to compete immediately after the return to sea level and/or use altitude training as a tool to improve muscle power levels of athletes without tapering goals, especially in highly trained power athletes, since their window of adaptation for further power enhancement is smaller. 2022-07-13T07:06:16Z 2022-07-13T07:06:16Z 2022-07-05 preprint This is an original manuscript of an article published by Taylor & Francis in European Journal of Sport Science on the 5th of July of 2022, available at: http://www.tandfonline.com/10.1080/17461391.2022.2089055. http://hdl.handle.net/10481/75965 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional
