Níveis de potência muscular em atletas de futebol e futsal em diferentes categorias e posições

Abstract

RESUMOEste estudo objetivou identificar a potência de membros inferiores em jogadores de futebol e futsal, comparando o counter movement jump (CMJ) entre modalidades, posições adotadas e categorias. Participaram 61 atletas de futebol das categorias Sub17, Sub20 e profissional e 28 de futsal das categorias Sub20 e profissional. Utilizou-se uma plataforma de força Quattro Jump do tipo piezoelétrica. Foi utilizada estatística descritiva, teste t de Student e análise de variância a p < .05. Não foi reportada diferença significativa no CMJ entre os atletas de futebol e futsal (p = .85). Entre as posições adotadas pelos jogadores de futebol encontrou-se diferença significativa (p = .02) apenas entre os centrais e os médios. Nos atletas de futsal não foi verificada diferença significativa entre as posições (p = .69). Quando comparadas as categorias também não foram constatadas diferenças significativas, tanto no futebol (p = .12), quanto no futsal (p = .47). Pode-se concluir que os atletas de futebol e futsal parecem apresentar níveis semelhantes de potência muscular. Os centrais apresentaram maiores níveis de potência quando comparados aos médios, porém no futsal os atletas apresentaram níveis similares de potência. Independente da categoria, tanto os atletas de futebol quanto de futsal, apresentaram níveis semelhantes de potência muscular.

Adaptações nas capacidades físicas de atletas de futsal da categoria sub 18 no decorrer de uma temporada competitiva

“…The power of the lower limbs is of fundamental importance for futsal players, as is required in the decisive moments of the match, whether in situations of counterattack, recovery of ball possession or even in trying to prevent a goal. In this study, it was measured by applying the jumping tests, which were also applied in other studies, thus enabling the comparison with values reported by Gorostiaga et al 21 and Silva et al 22 for CMJ, which presented the following values: 38.1 ± 4.1 cm and 43.8 ± 6.8 cm during the preparatory period, respectively. In addition, Silva et al 22 reported that U-20 athletes jumped on average 43.7 ± 4.1 cm, values, very close to those of the current study, indicating that the evaluated subjects had values similar those of above studies, demonstrating a performance level compatible for futsal players.…”

“…The power of the lower limbs enables athletes to perform quick and explosive movements in a short time, which is a quite requested feature in futsal. This capacity, when trained in a specific way, has a high degree of transfer to motor actions performed in court such as making jumps and sprints, enabling an improved performance of athletes during a match 21,22 .…”

Physiological Profile of Brazilian Elite Soccer Players: Comparison between U-17, U-20 and professionals

“…Th us, our results point to the need of specifi c training approaches for diff erent age categories and playing positions. Silva et al (2012) reported the level of muscle power in soccer athletes, and examined diff erent categories and positions using the vertical jump test. No signifi cant diff erences were reported among the U-17, U-20 and adult professional categories, although it was noted there were diff erences between midfi elders and defenders.…”

“…Participants were also directed to abstain from any nutritional or ergogenic supplements. Th e Faulkner protocol was used for body fat analysis (Faulkner, 1968), the counter-movement jump test (with arms) was used for vertical jump height (Silva et al, 2012) and the yo-yo intermittent recovery test was used to estimate the maximum oxygen consumption (VO 2max ) (Castagna, Impellizzeri, Chamari, Carlomagno, & Rampinini, 2006). All subjects were instructed to refrain from participating in any physical training during the study period, except those prescribed as part of the investigation.…”

“…Knowledge of strength levels in players is therefore important for a proper training prescription in order to gain optimal performance (Hamzeh & Head, 2004). Th e strength of soccer players has been previously studied by measuring squats and vertical jumps (Dauty, Bryand, & Potiron-Josse, 2002;Silva et al, 2012;Wisløff , Helgerud, & Hoff , 1998), as well as by specifi c strength tests using isokinetic dynamometry (Agre & Baxter, 1987;Gioft sidou et al, 2008;Hamzeh & Head, 2004;Hom, Steen, & Olstad, 2005). Studies have demonstrated muscle strength increases as young athletes grow and develop (Le Gall, Laurent, & Rochcongar, 1999), and that muscle balance is fundamental for young players in order to advance to levels of excellence using specifi c training (Hom, Steen, & Olstad, 2005).…”
