Relação entre o ângulo quadriciptal (ÂQ) e a distribuição da pressão plantar em jogadores de futebol

Abstract

Objectives: To determine whether there is an association between the Q-angle (Q) and the distribution of plantar pressure in football players, and to compare the characteristics of these athletes with non-practitioners of this sport. Methods: 121 male participants were selected: 50 football practitioners (FP) and 71 non-practitioners (NP). We concurrently evaluated the Q-angle and the plantar pressure through the software of postural assessment (SPA) and the F-Mat System, respectively. To verify the correlation between the Q-angle and peak pressure values in four segments of the foot (medial and lateral forefoot, medium-foot and hind-foot), the Pearson coefficient (r) for parametric analysis was used. The independent t-test was used to compare these variables between the groups. Key words: football; Q-angle; plantar pressure; baropodometry; photogrammetry. ResumoObjetivos: Verificar possível associação entre ângulo quadriciptal (ÂQ) e distribuição de pressão plantar em jogadores de futebol, Palavras-chave: futebol; ângulo Q; pressão plantar; baropodometria; fotogrametria.

Protocols of balance assessment using baropodometry in healthy individuals - systematic review

“…Braz and Carvalho 20 and Lins et al 23 used acquisition times of 10 seconds and did not fi nd signifi cant diff erences in stabilometric variables between the initial and fi nal evaluations. Lopes et al 12 and Machado et al 24 used acquisition time of 30 seconds.…”

“…A method of standardization of the feet has been shown by Braz and Carvalho 20 , where the responsible evaluator positioned the second fi nger, which is considered the middle line of the foot and axis of the tibiotarsal joint, towards the ipsilateral calcaneus, without losing contact with the platform, in order not to change the pressure exerted by the volunteer. This methodology was applied for possible changes in position during collection could generate limitations in the study.…”

“…According to the number of collections, some studies conducted three for each position 14,15,17,24,25 and just two 7,20,23 , with some studies having the absence of such information. According to literature data, to obtain a good data reliability it is required from three to fi ve collections in each position 1 .…”

Síndrome de Leigh e implicações para prática fisioterapêutica: relato de caso

“…Esse resultado pode ser atribuido pela flexão apresentada pelo joelho esquerdo da paciente no momento da avaliação, já que não houve diferença significante em relação ao comprimento dos membros inferiores. Na análise do ângulo Q (A9 e A10) a adolescente encontra-se com geno valgo a esquerda 13 .…”

Sport practice and plantar pressure in children aged 10–18 years: evaluation using Namrol® Podoprint ®

“…Therefore, special attention to the distribution of plantar pressure is necessary [ 2 ]. Baropodometry consists of the quantification of anteroposterior and lateral oscillations of the sole of the foot, while the individual remains under a pressure platform [ 3 ]. The goal of this investigation is to verify if there is an association between students' sports practice and their distribution of plantar pressure and to analyse whether there are differences regarding plantar pressure distribution between students who practice and those who do not practice a specific modality (volleyball, swimming or soccer).…”
