This study investigates the external and internal loads experienced by male high-performance athletes during indoor and beach volleyball matches. Twelve national-level players participated in three simulated beach volleyball matches and one simulated indoor volleyball match. Game activities were analyzed using the VXSport tracking system to evaluate various indicators of movement and physical exertion. Statistical analyses were conducted to compare the two volleyball formats, focusing on objective measures of external and internal load. Results revealed no significant differences in most external load indicators, with the exception of a higher number of jumps under 20 cm in beach volleyball. However, beach volleyball was associated with significantly greater internal load, including higher mean and peak heart rates, increased time spent in the 90-100% maximum heart rate zone, and greater overall energy expenditure. These findings highlight the influence of environmental factors - particularly sand surface - on internal physiological stress. The results underscore the importance of individualized training programs tailored to the specific demands of each volleyball format. This study provides practical insights and real-world load indicators to inform training strategies for athletes and coaches in both beach and indoor volleyball contexts.
