Análise da relação entre flexibilidade e rigidez passiva dos isquiotibiais

Abstract: Introduction:The terms stiffness and flexibility, which refer to muscle properties, are frequently used as synonymous in the literature. However, these two muscle properties have distinct definitions. Objective: To investigate the contribution of the measure of flexibility to the passive stiffness of the hamstrings. Methods: Stiffness and flexibility were measured in 33 healthy individuals. An isokinetic dynamometer registered the resistance torque offered by the hamstrings during knee passive extension at 5 o

“…Several tests and scales are proposed for evaluating the flexibility 37,38 and spasticity 39 of the ankle plantar flexors and often these tests are used in clinical practice to infer about ankle passive stiffness 40 . However, in contrast to the passive stiffness, flexibility measurement is not only determined by mechanical properties, since it is influenced by individual levels of tolerance to stretching 41 .…”

“…However, in contrast to the passive stiffness, flexibility measurement is not only determined by mechanical properties, since it is influenced by individual levels of tolerance to stretching 41 . Some studies have shown that less than 30% of the variability found in stiffness measurement may be explained by flexibility 40,42 . The spasticity involves reflex muscle activation during the performance of a passive movement 43 , while the measurement of the passive stiffness requires the electromyographic silence of the muscles 1 .…”

“…A flexibilidade muscular é definida como a habilidade de um músculo alongar-se, permitindo que a articulação se movimente através de toda a amplitude de movimento (ADM), irrestrita e sem dor. A perda da flexibilidade e consequente redução da ADM ocorre, entre diversas condições, pela diminuição da capacidade de um músculo deformar-se, relacionada à perda de força muscular e à presença de encurtamentos [1][2][3][4][5] . A redução da flexibilidade, principalmente em isquiotibiais, pode gerar desequilíbrio postural, déficit da ADM do joelho, do quadril e da coluna lombar e dificuldade em realizar movimentos amplos 3,5 .…”

“…A redução da flexibilidade, principalmente em isquiotibiais, pode gerar desequilíbrio postural, déficit da ADM do joelho, do quadril e da coluna lombar e dificuldade em realizar movimentos amplos 3,5 . Essas alterações contribuem para lesões e disfunções musculoesqueléticas 2,6 . Diversas condições articulares e periarticulares levam à perda ou à redução da força muscular.…”
