Acute and Chronic Training Load Effects on Elite Volleyball Players

This study investigated the acute and chronic effects of training load on vertical jump height, agility, and recovery status in elite male volleyball players. Eleven athletes' internal load was monitored over two 3-week periods, with external load quantification and recovery status assessed in weeks 3 and 7. Countermovement jump and agility tests were conducted pre- and post-training sessions. Results showed higher training load in the first period compared to the second, influencing motor performance, with better outcomes observed in the second period. No negative acute effects on motor performance were found; two sessions showed post-session CMJ improvement, potentially influenced by jump frequency and quantity within those sessions. Periods of high or reduced TL impacted motor performance, specifically vertical jump height and agility. Vertical jump results proved sensitive to TL fluctuations, providing insights into training status, recovery, and motor performance. Reducing TL strategically during the season facilitated physical recovery and positive motor performance adaptations. This suggests managing training load strategically can optimize performance and recovery in elite volleyball players.
