Neuromuscular Adaptations after an Altitude Training Camp in Elite Judo Athletes Tomazin, Katja Štirn, Igor Almeida, Filipa Padial Puche, Paulino Bonitch Góngora, Juan Germán Morales Artacho, Antonio Jesús Strojnik, Vojko Feriche Fernández-Castanys, María Belén Elite athletes Strength training Twitch H-reflex Voluntary activation The aim of this study was to investigate neuromuscular adaptations in elite judo athletes after three weeks of power-oriented strength training at terrestrial altitude (2320 m). Nineteen men were assigned to altitude training (AL) (22.1 ± 2.3 years) and sea level training (SL) (22.6 ± 4.1 years). Neuromuscular assessment consisted of: (1) maximal isometric knee extensor (KE) torque, (2) KE rate of torque development (RTD), (3) quadriceps activity and voluntary activation, (4) soleus Hreflex, (5) quadriceps single (TTW) and double twitch torque (TDB100) and contraction time (CTTW). There were no significant differences between groups at baseline for any of the observed parameters. Significant differences were found between groups in terms of change in RTD (p = 0.04). Cohen’s d showed a positive significant effect (0.43) in the SL group and a negative significant effect (−0.58) in the AL group. The difference between groups in changes in CTTW as a function of altitude was on the edge of significance (p = 0.077). CTTW increased by 8.1 ± 9.0% in the AL group (p = 0.036) and remained statistically unchanged in the SL group. Only the AL group showed a relationship between changes in TTW and TDB100 and changes in RTD at posttest (p = 0.022 and p = 0.016, respectively). Altitude induced differences in muscular adaptations likely due to greater peripheral fatigue. 2021-07-05T08:07:14Z 2021-07-05T08:07:14Z 2021 info:eu-repo/semantics/article Tomazin, K.; Almeida, F.; Stirn, I.; Padial, P.; Bonitch-Góngora, J.; Morales-Artacho, A.J.; Strojnik, V.; Feriche, B.
