“…Volleyball involves low-to-high-velocity collisions between the ball and a player, the volleyball behaviour is unique for each different type and the interaction between the player and the ball depend on the ball type and the incident velocity. In collision injuries, the varying combinations of kinetic energy lost and peak impact force may be useful to understand the role of each of these variables [20]. In general, little is known about how the collision in itself is harmful and the question becomes more complicated about the athletes.…”

Volleyball players are exposed to the possibility of several well recognized injuries, among which microvascular abnormalities are the less described and studied, although they could diminish their ability and performance. Capillaroscopy is a simple, non-invasive method to diagnose vascular abnormalities in athletes suffering for the consequences of repeated application of pressure by local trauma on the fingertips. The detected capillaroscopic picture will be the base for the follow-up and will indicate the possible need for further investigations aimed at excluding other occulted conditions. At our knowledge, this is the first report describing and documenting the related microvascular abnormalities in a volleyball player. This case emphasizes the fact that volleyball players among other athletes, whose hands are exposed to repeated fingertips trauma may suffer from microcirculation damage, for which reason they should be able to access an effective health surveillance program able to detect the first signs and offer the most appropriate clinical support.

“…When a volleyball hits an athlete's body, forces and energies had transferred to anatomical structures, including skin, muscles, tendons, ligaments, and bones. These may lead to sports injury, so the mechanical properties of volleyballs, especially the stiffness of the ball to reduce the forces on the limbs of athletes, can play a role in causing injury [1,2]. Therefore, this study aimed to compare the impetus of new beta volleyball designed with other volleyballs available to reduce the rate of sports injuries in volleyball athletes.…”

Background and aim The sport of volleyball requires constant contact of sports balls with the hands of athletes, Therefore, the sports balls used in volleyball can play an important role in the performance of athletes. therefore, the aim of the present study is to compare the impulse of the new BETA volleyball designed with other samples volleyballs using the Bertak model force plate made in the United States. Material and Methods Examples of Mikasa volleyballs, model V200W, made in Japan, Fox volleyball, model Spain, made in France and Old and new BETA volleyballs made in Iran with a weight range of 260 to 270 grams with a circumference of 66 cm were used in the present study, Finally, the impulses of volleyballs were compared using a Bertek model force plate machine. Results In line with the findings of the present study, there is a significant difference between the impulse of the sample of the new BETA volleyball ball designed at compared to the volleyball sample of the old beta design in the direction of the vertical axis (P = 0.014). in this regard, the post hoc test showed that there is no statistically significant difference between the sample of the new BETA volleyball at compared to the sample of Fox volleyball (P = 0.102) and Mikasa volleyball that is used in official competitions (P = 0.662). Conclusion Therefore, the use of a new BETA volleyball designed to reduce the rate of sports injuries is recommended to all coaches, referees, athletes and officials in the field of volleyball.
