Monitoring psychophysiological and neuromuscular parameters in beach volleyball high-performance athletes

The aim of the study was to monitor and compare changes in psychophysiological and neuromuscular parameters in the training period (TP), during and after competition between blockers and defenders in high-performance beach volleyball (BV). Eight male high-performance BV players, participated in this study. The study monitored heart rate variability (HRV), countermoviment jump (CMJ), training impulse (TRIMP), monotony, strain, total weekly training load (TWTL) and daily training load (DTL). There was no significant difference in HRV, monotony, and CMJ between TP vs. during and after competition (p> 0.05). However, results observed showed that TRIMP, TWTL, DTL and Strain in the TP was significantly higher than the competition and post-competition (p< 0.05). There was no significant difference in the CMJ and psychophysiological parameters between defenders and blockers players (p< 0.05). We conclude that the changes in psychophysiological and CMJ parameters were similar between blockers and defenders and the training loads were well distributed with increases in the first two weeks before the competition and reduced training loads during and after the competition.
