Abstract in Portuguese
Com uma amostra de 12 jogadores de basquetebol, e 13 jogadores de voleibol do sexo masculino com faixa etária entre 18 à 21 anos procurou-se atingir os seguintes objetivos: 1-determinar as características antropométricas e a composição corporal dos jogadores, 2- avaliar a potência muscular máxima (absoluta e relativa) dos músculos extensores do joelho através da dinanometria isocinética, 3-verificar a relação entre o teste de potência isocinética e o teste de salto vertical e 4-comparar os resultados obtidos entre os jogadores das duas modalidades esportivas. Os jogadores foram submetidos a uma avaliação antropométrica e dois testes de potência muscular. A composição corporal foi determinada através da equação proposta por JACKSON 7 POLLOCK (1979). O teste de salto vertical foi realizado sem o auxílio dos membros superiores e a dinamometria isocinética executada para o movimento de extensão dos joelhos às velocidades de 60, 180,240 e 300 graus por segundo. Foi verificado que os jogadores de basquetebol eram mais altos, mais pesados e possuíam maior quantidade de gordura corporal que os voleibolistas. Comparados em termos absolutos os dois grupos de jogadores apresentaram desempenho neuromuscular semelhante. Relativo ao peso corporal os jogadores de voleibol foram superiores no salto vertical e na potência muscular isocinética máxima à 60 graus por segundo, e no teste de salto vertical quando corrigido pela massa corporal magra. No relacionamento entre o teste de potência muscular isocinética máxima e o teste de salto vertical foram encontradas correlações moderadas para altas em termos absolutos nas velocidades de 180 e 300 graus por segundo para os jogadores de basquetebol e 180 e 240 graus por segundo para os de voleibol. Resultados semelhantes ocorreram para os praticantes de basquetebol relativo ao peso corporal e a massa corporal magra, contudo para os voleibolistas as relações foram de baixas para moderadas relativas as variáveis de composição corporal

Abstract in English
The aims of this study were: 1- to determine the anthropometric characteristics and body composition of players; 2- to evaluate the maximal muscle power of the knee extensors muscles with the isokinetics dynamometry; 3- to determine the relationships between the test of isokinetics power and the vertical jump test; 4- to compare the results between sports. A sample of 12 basketball players and 13 volleyball players was evaluate in several anthropometric measurements and in two tests of muscle power. Body composition was determined through the equation proposed by JACKSON and POLLOCK (1978). Vertical jump test was made without the arm movements, and the isokinetic muscle power test of the knee extensores was made in four speeds: 60,180, 240 e 300 degrees per second. The results showed that the basketball players were taller, heavier and fatter than the volleyball players. There were no significant diferences in power output. When power was related to body weight, volleyball players showed higher values in the vertical jump test and the isokinetic power test at 60 degrees per second and in the vertical jump test when corrected by lean body mass. Relationships between maximal power tests showed from moderate to high degree between the isokinetic power test at 180 and 300 degrees per second and the vertical jump test for basketball players. Volleyball players showed similar results at 180 and 240 degrees per second. Similar results were found when tests were corrected for body weight and lean body mass for basketball players, but in volleyball players relationships were from low to moderate when the same procedure was made
