(Universidade Federal do Pará, 2021-12-21) LOPES JÚNIOR, Doriedson Barbosa; SILVA, Marília Passos Magno e; http://lattes.cnpq.br/9123524811984821; https://orcid.org/0000-0002-7322-6364
Sitting volleyball is a paralympic sport that has shown significant growth in competitive terms in recent years, increasing the need for methods of evaluating technical-tactical aspects and physical fitness that help in monitoring the level of performance and increase in sports performance in the modality. The present systematic review was conducted in accordance with the guidelines of the Main Items for Reporting Systematic Reviews and Meta-Analyses (PRISMA) and aimed to identify and analyze indicators of performance and physical fitness in sitting volleyball players. The searche was carried out in four databases (Scopus, Pubmed, Web of Science and Scielo) and studies that quantitatively evaluated performance indicators or physical fitness components in sitting volleyball athletes of any gender, age or competitive level were included. The methodological quality of the articles included was evaluated by the Critical Review Form for Quantitative Studies (LAW et al., 1998) and the results presented through narrative synthesis. In total, 37 studies were included, with an average quality score of 72.25%. The findings showed that attacking and blocking were the main terminal actions in sitting volleyball. Significant correlations between physical fitness measures (power, speed, agility, endurance, flexibility, reaction speed and body composition) with specific technical skills were identified. While limited evidence indicates that: male athletes perform better than female athletes; that elite athletes are physically and technically superior to sub-elite ones. In addition, the studies did not point out significant differences in the effectiveness in game actions between athletes of different functional classes.

The relative age effect on brazilian elite volleyball
(Universidade Federal do Pará, 2018-10) PARMA, Juliana Otoni; PENNA, Eduardo Macedo
The relative age effect (RAE) refers to the advantage of the athletes born on the first months of the sport selection period compared to those born months later during such a selection process, which tends to favor athletes who are in a more developed maturational stage or those who have more advanced physical development compared to their younger counterparts born in the same year. This advantage occurs mainly in sport whose physical characteristics are determinant for obtaining success, such as volleyball, which leads to the premature exclusion or dropout of potential talents from sport. This study aims at assessing the RAE presence in Brazilian men’s and women’s elite volleyball by analysing the number of athletes who were born in each trimester of the year and had been ranked to the main national Super Leagues. The results showed no effect related to the RAE in Brazilian women’s elite volleyball, whereas there was a higher representation of male athletes born in the first trimester compared to the ones born on the 3rd and 4th trimesters. These results point to a need for better understanding the causes and consequences of RAE in Brazilian men’s volleyball in order to avoid premature exclusion or dropout of potential talents, thus, enabling an even greater development of this sport in the country.
