Abstract

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 H-reflex, (5) quadriceps single (T TW ) and double twitch torque (T DB100 ) and contraction time (CT TW ). 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 CT TW as a function of altitude was on the edge of significance ( p = 0.077). CT TW 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 T TW and T DB100 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.
