Treze jogadores profissionais de futebol participantes da segunda divisão do campeonato paulista, foram avaliados no início da pré temporada (T1) e após 07 semanas (T2) de treinamento. Os jogadores realizaram testes de saltos verticais: squat jump (SJ) e countermovement jump (CMJ), índice de força reativa (IFR=CMJ-SJ) e TW, potência pico (PP), média (PM) e índice de fadiga (IF). Após o TW, foram coletados 25 μl de sangue do lóbulo da orelha no 7º, 9º e 11º minuto para determinação da concentração pico de lactato ([Lac]). A comparação entre as variáveis foi realizada pelo teste t de Student para amostras dependentes, sendo adotado o nível de significância de 5% (p<0,05). Foram observadas melhoras significantes no SJ (T1= 32,76 ± 3,88; T2= 38,03 ± 5,49), CMJ (T1= 37,76 ± 4,88; T2= 40,86 ± 5,62), PP (T1= 10,97 ± 0,90; T2= 12,32 ± 1,12) e PM (T1= 8,34 ± 0,82; T2= 9,78 ± 0,99), respectivamente. No entanto, alterações no IF e [Lac] não foram... / The present study investigated vertical jump and wingate test (TW) performance of soccer players in the beginning of season and after 7 weeks of training. Thirteen professional second division soccer players from the Paulista championship were tested on the beginning of the pre-season (T1) and after seven weeks (T2) of training. The players were submitted to vertical jump tests: squat jump (SJ) and countermovement jump (CMJ), reactive force index (IFR=CMJ-SJ) and TW, peak power (PP), mean power (PM) and fatigue index (IF). After TW, 25 μl blood was collected from the earlobe on the 7º, 9º and 11º minute to determine the highest blood lactate concentration ([Lac]). Comparison between variables was performed by Students’ t test for dependent sample, with a significance level of 5%. Were found significant improvements on SJ (T1= 32,76 ± 3,88; T2= 38,03 ± 5,49), CMJ (T1= 37,76 ± 4,88; T2= 40,86 ± 5,62), PP (T1= 10,97 ± 0,90; T2= 12,32 ± 1,12) e PM (T1= 8,34 ± 0,82; T2= 9,78 ± 0,99), respectively. Nevertheless, IF and [Lac] changes were ... (Complete abstract click electronic access below)
