摘要

闭合动力链练习已被用于康复和肌肉强化项目,如深蹲。在深蹲动态外翻的运动过程中,影响下肢所有运动学的变化往往会加剧,需要适应以尽量减少生物力学障碍。虽然有研究表明深蹲运动的有效性,但缺乏证据表明,相对而言,不同的适应在减少动态外翻方面的有效性。该研究的目的是评估和确定不同的适应下蹲运动在减少动态外翻的功效。因此,研究志愿者(n = 30)进行了三种类型的深蹲:自由深蹲、带松紧带深蹲和口头命令深蹲。采用深蹲运动时膝关节正面平面投影角度测量动态外翻,通过采集图像,利用Tracker和ImageJ软件进行分析。尽管在女性中有更多的病例,但与其他两种适应方式相比,自由下蹲更容易导致膝关节的医学化。虽然两种深蹲适应都有积极的结果,但只有口头指令下的深蹲能显著减少动态外翻,这表明这是最好的适应。关键词:缬草;运动疗法。运动的活动。简历练习(resume exerciciicis)是一种专业的电影技术训练项目,主要用于肌肉运动,肌肉运动,肌肉运动和肌肉运动。 mico - mico, alteracao que afeta toda cinematica do membro - inferior, tende - torar - exacerbado, sendo -必需品adaptacoes - comto直观地最小化干扰生物- mico - mico。对不同的适应性进行了比较,并对不同的适应性进行了有效的分析,从而使不同的适应性最小化。目的:探讨不同适应条件下不同运动方式对人体运动的影响。Para to, os voluntarios do estudo (n=30),三种形式的agachamentos: agachamento live, agachamento com bananda elastica, agachamento com comando verbal。O valgo dino microsofi mensurado mediante O ngulo de projecto no plano front do joelho durante O imimento de agachamento,图像捕获和图像分析的图像捕获和跟踪软件Tracker e ImageJ。这些主要原因包括:男性、女性、男性、女性、男性、女性、女性、女性、女性、女性、女性、女性、女性、女性、女性、女性和女性。Embora amtacoes de agachamento呈递阳性结果,agachamento呈递阳性结果,apbora amachamento呈递阳性结果,apbora amachamento呈递阳性结果,apbora amachamento呈递阳性结果,apbora amachamento呈递阳性结果,apbora amachamento呈递阳性结果。Palavras-chaves: Geno Valgo。运动障碍。Atividade Motora。

Comparative Analysis of the Effect of the Different Adaptations of the Squat Exercise on the Knee Frontal Plane Projection Angle
Closed kinetic chain exercises have been employed in rehabilitation and muscle strengthening programs, such as squatting. During the movement of the squat dynamic valgus, a change that affects all kinematics of the lower limb, tends to become exacerbated, necessitating adaptations in order to minimize the biomechanical disorder. Although studies have shown the effectiveness of squatting exercises, there is a lack of evidence to demonstrate, comparatively, the effectiveness of different adaptations in the decrease of dynamic valgus. The objective of the study was to evaluate to identify the efficacy of different adaptations in squatting exercise in the reduction of dynamic valgus. Therefore, study volunteers (n = 30) performed three types of squats: free squatting, squatting with elastic band and squatting with verbal command. The dynamic valgus wasmeasured by the knee frontal plane projection angle during the squatting movements, through captured images and analyzed by the software Tracker and ImageJ. Despite more cases in women, in both sexes, free squatting presented greater cases of medicalization of the knee than in comparison to the other two adaptations. Although both squat adaptations presented positive results, only squatting with verbal command showed a significant reduction of the dynamic valgus pointing out that this is the best adaptation treated.   Keywords: Genu Valgum.
