A amostra selecionada de forma voluntaria nao probabilistica foi constituida por 29 atletas de tenis da Categoria 12 Anos Masculino, participantes do Ranking Brasileiro. Para a coleta de dados utilizou-se um Questionario de Anamnese, o Ranking Brasileiro, a Ficha Tecnica da Confederacao Brasileira de Tenis e a Escala de Percepcao de Competencia (EPC). Para a analise dos dados foi utilizado o teste de regressao linear simples, adotando-se como intervalo de confianca p.0.05. Os resultados revelaram uma correlacao positiva entre o Ranking e a PC Atletica, embora nao tenham permitido determinar a relacao entre a Percepcao de Competencia Pessoal dos tenistas com as posicoes por eles ocupadas no Ranking Brasileiro. Altas correlacoes foram encontradas entre o Ranking e o Aproveitamento Esportivo (p<0,01 e r=0,88) e entre o Ranking e a Experiencia Geral (p<0,01 e r=0,82). Com o presente estudo, pode-se concluir que os tenistas da Categoria 12M, independentemente das posicoes ocupadas no Ranking Brasileiro, apresentam uma alta PC Atletica e que a relacao entre o ranking, o aproveitamento esportivo e a experiencia geral dos atletas parece estar associada as regras estabelecidas pela CBT, que atribui pontos proporcionais as rodadas alcancadas pelos atletas, alem de premiar com pontos os jogadores que participam de torneios oficiais mesmo perdendo na primeira rodada. / Abstract: The purpose of this correlacional descriptive design research was to investigate the association of perceived competence of male tennis players; aged under 12 years old with their Brazilian fs ranking positions, their general experience and their success sport rate. The study fs sample was composed of 29 boys under 12 years old from national Brazilian Ranking. Were used as instruments the Perceived Competence Scale (Harter, 1985, adapted to Portuguese by Fiorese, 1993), the Brazilian Ranking, the player fs technical sheet of Brazilian Tennis Confederation (CBT) and a questionnaire made by author. All the variables were tested with normality test Kolmogorov-Smirnov and the variable general experience was also tested through bivariate normality test with all the others variables. Multiple regression and Linear regression was conduct with all variables and the adopted interval confidence was p.0,05. The results showed that athletic perceive competence and Ranking was significant but weak (p=0,44 and r=0,38) therefore the H1 could be partially accept. It was not possible to confirm that the players on the best positions of the Brazilian Ranking has better perceived competence than the players on the lower positions of the Brazilian ranking. The results showed also that tennis players under 12 has high perceived competence (3,17 }0,44). The high correlations between Ranking, success sport rate (p<0,01 e r=0,88), and their General Experience (p<0,01 e r=0,84), allowed to accept that these results are due the rules of Brazilian ranking imposed by CBT that give points not only for player who wins but also for the ones who loses in the first round of the officials tournaments.
