Abstract
Introdução: Os jogos com campo reduzido (JCR), tem sido indicados como forma de treinamento atendendo o princípio da especificidade com intensidade potencial para proporcionar estímulos suficientes para causar adaptações no sistema cardiorrespiratório. O monitoramento da Frequência Cardíaca (FC) pode fornecer avaliações mais confiáveis da intensidade do treino que a FC. Objetivo: Verificar a interferência do ‘’coringa’’ no comportamento da FC em diferentes mini-jogos de futebol 4 x 4. Metodologia: A amostra deste estudo foi composta por 16 atletas homens (14 ± 0,18 anos; 56,2 ± 9,05 kgs; 1,76 ± 6,7 cm), da categoria Sub-15 de um clube de formação de futebol de Minas Gerais. Foram realizados dois mini jogos em 4x4 com goleiros e 4x4 + coringa com goleiros. A FC de todos os jogadores foi monitorada pelo sistema Polar, continuamente durante cada mini jogo. A FC foi registrada na condição de repouso, ao final de cada estímulo de mini jogo, e ao final da recuperação. Posteriormente os valores em bpm foram transformados em percentual para caracterização da intensidade, empregando as seguintes fórmulas: FC Obtida = FC Repouso + % (FCMcal – FC Repouso). A estimar a FCM foi utilizada a fórmula FCMcal = 208 – (0,7 x idade em anos) (TANAKA et al., 2018). Cada mini jogo teve uma duração de três minutos com três minutos de intervalo, realizado em três séries. A área de mini jogo foi igual nas duas situações, sendo de 42 x 27 m². O número de toques na bola era ilimitado. Cada grupo e quatro jogadores era composto por atletas de diferentes funções táticas (zagueiro, lateral, meio campista, atacante). O consumo de líquidos foi de forma ad libitum. O tratamento estatístico foi para a comparação da FC tanto em bpm quanto em % entre as séries com e sem coringa, foi utilizado o Teste T não pareado de Student. Também foi utilizado o mesmo teste estatístico para comparar a intensidade entre as séries de cada forma de treino de maneira isolada. Em ambos os casos foi considerado o nível de significância de p<0,05 Resultados: Considerando os valores percentuais ao final de cada uma das séries dos mini jogos, foram para a situação sem coringa (88,1± 6,59% S1; 88,4± 5,11% S2; 90,5 ± 5,77% S3), enquanto que com a presença de coringa foi de (87,0 ± 4,44% S1; 89,4 ± 6,51% S2; 88,7 ± 5,60% S3). Não houve diferença significativa entre as duas formas de mini jogo. Conclusão: A presença do coringa no mini jogo 4 x 4 em jovens da Sub-15, não interfere na resposta da FC ao longo das séries de treino.
Introduction: Small-field games (SFG) has been indicated as a form of training in compliance with the principle of specificity with potential intensity to provide sufficient stimuli to cause adaptations in the cardiorespiratory system. Heart Rate (HR) monitoring can provide more reliable assessments of training intensity than HR. Objective: To verify the interference of the '' joker '' in the behavior of the FC in different mini soccer games 4 x 4. Methodology: The sample of this study was composed of 16 male athletes (14 ±0.18 years, 56.2 ± 9.05 kgs, 1.76 ± 6.7 cm), from the Sub-15 category of a soccer training club in Minas Gerais General. There were two mini-games in 4x4 with goalkeepers and 4x4 + joker with goalkeepers. The FC of all players was monitored by the Polar system, continuously during each mini-game. HR was recorded in the resting condition, at the end of each mini-game stimulus, and at the end of recovery. Subsequently, the values in bpm were transformed into percentage for intensity characterization, using the following formulas: MHRObtained = HR Rest +% (MRH cal - HR Rest). The estimated MRH was the formula MRHcal = 208 - (0.7 x age in years) (TANAKA et al., 2018). Each mini-game had duration of three minutes with three minutes of interval, carried out in three series. The mini- game area was the same in both situations being 42 x 27 m². The number of rings on the ball was unlimited. Each group and four players were composed of athletes of different tactical functions (defender, side, midfielder, striker). The consumption of liquids was ad libitum. The statistical treatment was used to compare the HR in both bpm and% between the series with and without wildcard, the Student's unpaired T test was used. We also used the same statistical test to compare the intensity between the series of each form of training in an isolated way. In both cases, a significance level of p <0.05 was considered. Results: Considering the percentage values at the end of each of the mini-games series, they were for the situation with no joker (88.1 ± 6.59% S1, 88.4 ± 5.11% S2,90.5 ± 5.77 % S3), whereas the presence of wildcard was 87.0 ± 4.44% S1, 89.4 ± 6.51% S2, 88.7 ± 5.60% S3). There was no significant difference between the two forms of minigame. Conclusion: The presence of the wildcard in the mini-game 4 x 4 in Youth of the Sub-15, does not interfere in the response of the HR throughout the training series.
