“…Compared to other sports at angular speed of 180°/s, a few studies have shown average scores of the extensors lower than those of this study, similarly to the studies which analyzed futsal players (Ferreira et al, 2010), and soccer (Zakas, 2006;Fousekis et al, 2010;Silva et al, 2015), whilst other studies analyzing soccer players showed higher average scores (Da Fonseca et al, 2007;Daneshjoo et al, 2013). In the analysis of the knee flexors, studies with futsal players (Ferreira et al, 2010) and soccer (Zakas et al, 2006;Fousekis et al, 2010;Daneshjoo et al, 2013;Silva et al, 2015) also showed lower average scores whilst other studies showed average scores higher than the athletes of this study (soccer (Da Fonseca et al, 2007), rugby (Larrat et al, 2007) and handball (González-Ravé et al, 2014). At angular speed of 240º/s, all fields of sport analyzed (soccer (Zakas, 2006), rugby (González-Ravé et al, 2014), basketball (Schiltz et al, 2009) and volleyball (Shu & Zhou, 2011)), resulted in average scores higher than in this study, for both knee extensors and flexors.…”

“…However, two studies which analyzed professional soccer players showed higher average scores of flexors than the scores of the athletes of this study (Zabka et al, 2011;Daneshjoo et al, 2013). Compared to other sports at angular speed of 180°/s, a few studies have shown average scores of the extensors lower than those of this study, similarly to the studies which analyzed futsal players (Ferreira et al, 2010), and soccer (Zakas, 2006;Fousekis et al, 2010;Silva et al, 2015), whilst other studies analyzing soccer players showed higher average scores (Da Fonseca et al, 2007;Daneshjoo et al, 2013). In the analysis of the knee flexors, studies with futsal players (Ferreira et al, 2010) and soccer (Zakas et al, 2006;Fousekis et al, 2010;Daneshjoo et al, 2013;Silva et al, 2015) also showed lower average scores whilst other studies showed average scores higher than the athletes of this study (soccer (Da Fonseca et al, 2007), rugby (Larrat et al, 2007) and handball (González-Ravé et al, 2014).…”

“…Unlikely other sports such as soccer (Fousekis et al, 2010) and futsal (Ferreira et al, 2010) which have asymmetrical muscle requirements from the extensor and flexor knee muscles, the weightlifting requires bilateral symmetrical muscle functioning from these muscle groups (Preto et al, 2014;Reiser et al, 2014). In the analysis of the average PT scores of the extensor and flexor muscles at angular speed 60º/s, both limbs showed average scores higher than the average scores found in other sports such as soccer (Zakas, 2006;Fousekis et al, 2010;Eniseler et al, 2012;Daneshjoo et al, 2013), futsal (Ferreira et al, 2010), rugby (Brown et al, 2014), basketball (Schiltz et al, 2009;Carvalho et al, 2011), handball (González-Ravé et al, 2014, and volleyball (Markou & Vagenas, 2006;Shu & Zhou, 2011). However, two studies which analyzed professional soccer players showed higher average scores of flexors than the scores of the athletes of this study (Zabka et al, 2011;Daneshjoo et al, 2013).…”

Efeito do FIFA11+ e do treinamento convencional de handebol sobre força isocinética e equilíbrio

“…It is noteworthy that in this study, there was no muscular imbalance greater than 10% between the dominant and non-dominant limbs both in IG and CG, in both evaluated moments (pre-and post-test), indicating that the athletes in this study did not present this risk factor for injuries, since this indicative occurs when there are asymmetries higher than 10% between limbs 25 . However, athletes from both groups, both in the dominant and non-dominant limbs, presented flexors/extensors ratio below 50% before intervention, indicating muscle imbalance in the knee joint 26 , a factor that predisposes athletes to injuries in this joint.…”

Existe relacao entre o tipo de piso da quadra de futsal e respostas adaptativas da musculatura em praticantes de futsal masculino?

“…O desempenho dos atletas em quadra pode estar relacionado diretamente com o nível de preparo da musculatura exigida para a prática do futsal. O quadríceps e os isquiotibiais são os músculos mais exigidos no futsal, pois, destacam-se entre a musculatura mais trabalhada nos tiros curtos, médios e longos, paradas bruscas, chutes, disputas de bolas, saltos e as divididas 8 . Os músculos gastrocnêmios (medial e lateral) auxiliam na flexão plantar da articulação do tornozelo enquanto, A amostra foi constituída por dez acadêmicos praticantes de futsal, com faixa etária de vinte a trinta anos, do sexo masculino, oriundos dos cursos de Engenharias da UNESC.…”
