Resumo Objetivo: Verificar a relação da capacidade de sprints repetidos e salto vertical intermitente em atletas de basquetebol. Métodos: Foram avaliados 20 atletas adultos do sexo masculino (21,4 + 2,18 anos). Os atletas fizeram um teste de sprints repetidos (6x30metros) e de salto vertical intermitente (4x15 segundos). Resultados: Verificaram-se correlações negativas moderadas a forte entre o desempenho dos sprints com a altura do salto vertical (r= 0,459 a 0,612; p< 0,05), com exceção da fase de aceleração do sprint, que não apresentou correlação significativa com o salto vertical. Forte coeficiente de correlação intraclasse foi observado para o decréscimo de sprint e salto vertical (CCI = 0,814; p < 0,001). Conclusão: O desempenho do salto vertical apresentou maiores coeficientes de correlação com os sprints feitos em distâncias mais longas (> 20 metros), sugeriu que a aceleração no sprint pode ser considerada uma variável física com características específicas em relação à velocidade máxima de sprint e salto vertical.

Abstract Objective: To verify the relationship of repeated sprint ability and intermittent vertical jump in basketball athletes. Methods: Twenty male adult athletes were evaluated (21.4 + 2.18 years). All athletes performed a repeated sprint test (6x30 meters) and intermittent vertical jump (4x15 seconds). Results: There was a moderate to strong negative correlation between sprint performance and vertical jump height (r= 0.459 to 0.612; p< 0.05), with exception of the sprint acceleration phase that did not present significative correlation with the vertical jump. Strength intraclass correlation was observed for sprint decreases and intermittent vertical jump (ICC= 0.814; p<0.001). Conclusion: Vertical jump performance presented higher correlations coefficients with sprints performed in great distances (>20 meters), suggesting that sprint acceleration can be considered a physical variable with specifics characteristics in relation to maximum sprint speed and vertical jump.

Resumen Objetivo: Comprobar la relación entre la capacidad de sprints repetidos y salto vertical intermitente en jugadores de baloncesto. Métodos: Se evaluó a 20 jugadores adultos de sexo masculino (21,4 + 2,18 años). Todos los jugadores realizaron una prueba de sprints repetidos (6 × 30 m) y de salto vertical intermitente (4 × 15 s). Resultados: Se comprobó la existencia de correlaciones negativas de moderadas a fuertes entre el desempeño de los sprints y la altura del salto vertical (r = 0,459-0,612; p <0,05), con excepción de la fase de aceleración del sprint, que no presentó ninguna correlación considerable con el mismo salto vertical. Se observó un fuerte coeficiente de correlación intraclase en el descenso del sprint y el salto vertical intermitente (CCI = 0,814; p <0,001). Conclusión: El desempeño del salto vertical presentó mayores coeficientes de correlación con los sprints realizados en distancias más largas (>20 m), lo que sugiere que la aceleración en el sprint puede considerarse una variable física con características específicas en relación con la velocidad máxima de sprint y salto vertical.

The purpose of this paper was to validate the ability of automated devices to measure the velocity of the upper limbs. Thus, 144 students, from 8 to 17 years old, both sexes, participated in the study in a social project in the city of Natal/RN. The Automated Tapping Test (AATT) was developed following the dimensions of the original EUROFIT test, but built out of metal parts, so that the calibration was more accurate and could be read as an electronic signal by the integrated circuit. The upper limb velocity test was applied in three steps: before performing the original test, all participants underwent a laterality check and then motor practice similar to the original test. After 30 minutes, the first step in the pattern established by the EUROFIT test battery was performed and 30 minutes later, the third stage, with the AATT. The measurement reliability of the automated apparatus was tested through intraclass correlations and a strong intraclass interaction coefficient of r = 0.901 was found. In conclusion, the AATT was found to be accurate and efficient as to what it is proposed to evaluate, being able to minimize the intra-evaluator error and to assist professionals in the sports.

Resumo A capacidade de sprints repetidos (CSR) é considerada um importante atributo para o basquetebol, sendo a aptidão aeróbica apontada como fator limitante para a repetição dos sprints. O objetivo do estudo foi verificar se a mudança no VO2PICO se relaciona com a melhoria da CSR após seis semanas de treinamento durante o período preparatório. 12 atletas de basquetebol universitário do sexo masculino com idade entre 18-24 anos participaram do estudo. Os atletas foram submetidos a uma avaliação da composição corporal, teste incremental máximo em esteira e teste de CSR (6x30-m) antes e após seis semanas de treinamento. Para efeito do estudo recorreu-se ao cálculo do delta percentual de mudança. Teste t pareado foi utilizado para verificar as diferenças após o treinamento e a correlação de Pearson e regressão linear simples foram utilizadas para verificar a relação entre o ∆%VO2PICO e ∆%CSR. Observou-se melhorias nos índices CSRPICO (t(1,11)= 2,7; p=0,023); CSRMÉDIA (t(1,11)= 2,8; p=0,019); CSRTOTAL (t(1,11)= 2,6; p=0,028); CSRDEC (t(1,11)= 2,9; p=0,015); e sprints 4 (t(1,11)= 2,4; p=0,037); 5 (t(1,11)= 3,14; p=0,010); e 6 (t(1,11)= 3,65; p=0,004) e VO2PICO (t(1,11)= -5,4; p<0,001); O ∆%VO2PICO se relacionou com o ∆%CSRMÉDIA (r=-0,667; r2= 0,383), ∆%CSRTOTAL (r= -0,673; r2= 0,393), ∆%Sprint 3 (r=-0,669; r2=0,387), ∆%Sprint 4 (r=-0,659; r2=0,371), ∆%Sprint 5 (r=-0,689; r2=0,413), ∆%Sprint 6 (r=-0,678; r2=0,400). É possível concluir que ~39% da melhoria das variáveis associadas com a manutenção de sprints repetidos (CSRMÉDIA; CSRTOTAL; sprints 3,4,5 e 6) dos atletas de basquetebol foi compartilhada pelo aumento de ~7,5% no VO2PICO.

Abstract The repeated sprints ability (RSA) is considered an important attribute for basketball, being aerobic fitness pointed out as limiting factor for repetition of sprints. The aim of the study was to verify if the change in VO2PEAK is related to the improvement of RSA after six weeks of training during preseason. Twelve male college basketball players aged 18-24 participated in the study. Players were submitted to body composition evaluation, maximum incremental treadmill test and RSA test (6x30-m) before and after six weeks of training. For the purpose of the study, the calculation of the change percentage delta was used. Paired t-test was used to verify differences after training and Pearson’s correlation and simple linear regression were used to verify the relationship between ∆%VO2PEAK and ∆%RSA. There were improvements in RSAPEAK (t (1.11) = 2.7, p = 0.023); RSAMEAN (t (1.11)= 2.8, p= 0.019); RSATOTAL (t (1.11)= 2.6, p= 0.028); RSADEC (t (1.11)= 2.9, p= 0.015); and sprints 4 (t (1.11)= 2.4, p= 0.037); 5 (t (1.11)= 3.14, p= 0.010); and 6 (t (1.11)= 3.65,p= 0.004) and VO2PEAK (t (1.11)= -5.4, p <0.001); ∆%VO2PEAK was related to ∆%RSAMEAN (r= -0.667; r2= 0.383), ∆%RSATOTAL (r= -0.673; r2= 0.393), ∆%Sprint 3 (r= -0.669; r2= 0.387), ∆%Sprint 4 (r= -0.659 ; r2 = 0.371), ∆%Sprint 5 (r= -0.689; r2 = 0.413), ∆%Sprint 6 (r= -0.678; r2 = 0.400). It is possible to conclude that ~ 39% of the improvement in variables associated with the maintenance of repeated sprints (RSAMEAN, RSATOTAL, Sprints 3,4,5 and 6) of basketball players was accompanied by an increase of ~ 7.5% in VO2PEAK.
