Existe diferença nos testes de força da dinamometria isocinética entre jogadores profissionais de futebol de campo e de futebol de salão?

Abstract

Objective: The objective of this study was to conduct a comparative analysis on isokinetic strength assessments between field and indoor male professional soccer players and correlate the findings with the higher levels of injury risk described in the literature. Methods: We analyzed 16 field soccer players and 15 indoor soccer players. All these professionals were male. Isokinetic muscle strength assessments were made on their knees. Results: The mean weight was 81.81 kg for field soccer and 80.33 kg for indoor soccer. The right and left peak extensor torque left and right for field soccer and indoor soccer were, respectively, 302.50 and 313.31 Nm and 265.20 and 279.80 Nm, and for flexors, 178 and 184.88 Nm and 158.27 and 154 Nm. The peak torque rates according to body weight for the left and right extensors for field soccer and indoor soccer were, respectively, 3.84 and 3.7 Nm/kg

Correlation between strength and flexibility of knee flexors and extensors muscles in youth soccer players

“…Our results are similar to those obtained by Pinto and Arruda (13) in which the mean of H:Q ratio was 57.7% and Leonardi et al (21) who obtained H:Q ratios to the right and left leg respectively 59.81 and 59.44% for soccer field players and 60.47% and 54.80% for indoor soccer players; But this study was conducted with professional soccer players, older, with more workload and consequently greater physical development.…”

“…The literature suggests that in most studies, the values of the H:Q ratio are obtained from isokinetic assessments (12,15,21) and difficultly are found studies that used this assessment to obtain the values of H:Q ratio. (19) Despite the lack of studies using the isometric contractions as evaluation method, high relations between isometric and isokinetic strength in both quadriceps and its antagonist have been observed.…”

“…Values below 60% have been associated with distension of the hamstring. (21) When there are significant imbalances between reciprocal musculature, there is a predisposition to injuries in joint or musculatures. (23,25) In the case of the adequacy of the H:Q ratio closer to normal, a period of training involving strengthening of hamstrings is extremely important.…”

Análise de indicadores de aptidão física em atletas de futebol de diferentes funções táticas

“…Neste contexto, a exposição crônica à prática do futebol tem se revelado uma estratégia eficaz na otimização desses processos adaptativos, promovendo ajustes benéficos na aptidão física, observados na força, velocidade, agilidade, composição corporal e alguns marcadores metabólicos como potência anaeróbia e aeróbia em diferentes faixas etárias (12)(13)(14)(15)(16), destacando-se também alguns fatores de risco associados e os efeitos profiláticos e terapêuticos desse modelo de intervenção (17)(18). Entretanto, em razão das diferentes funções táticas realizadas pelos futebolistas, diversos estudos tem analisado a especificidade dos processos adaptativos dessas posições, na perspectiva de produzir conhecimentos que possam contribuir no planejamento dos métodos de treinamento de forma a atender as respectivas características funcionais desses atletas, considerando também os aspectos relacionados às fases do crescimento e desenvolvimento (19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29). Neste contexto, o presente estudo teve como objetivo verificar o perfil de aptidão física de atletas de futebol de campo, nas diferentes funções táticas, analisando marcadores antropométricos e neuromusculares.…”
