“…the fibular muscles lose the ability to generate the eversor torque responsible for protecting the ankle-foot complex of the main mechanism of local injury, inversion associated with flexion planting. (17) In addition, the inversion and eversion movements are combined movements, acting in synergy with other musculatures. For the accomplishment of these movements properly it is necessary familiarization with the instrument and exact coordination of the movement.…”

Introduction:The ankle and foot are responsible for the support base of the whole body and variations in the foot posture influences the function of lower limbs. Objective: To observe whether there is a relationship between the isokinetic peak torque of ankle muscles with different types of foot. Method: The sample consisted of 32 volunteers, divided intentionally into 3 groups (normal, flat and cavus) according to the classification of the type of foot. They were evaluated in an isokinetic dynamometer Biodex 4 Medical Systems  , for analysis of ankle muscles peak torque in flexion and dorsal plantar, inversion and eversion in concentric contraction at 30 and 60°/s speeds. Results: There was positive moderate correlation between cavus group and the inversion peak torque in the dominant lower limb and negative moderate correlation on the not dominant lower limb. The flat foot group presented correlation with peak torque in the plantar flexion movement at a speed of 30°/s in non-dominant leg, which was negative moderate correlation. The normal foot group was correlated with peak torque of dorsiflexion movement in the dominant lower limb on 60 °/s speed and the non-dominant leg on 30°/s, been negative moderate correlations. Conclusion: The foot types were correlated with the ankle muscles, showing that alterations on the position of the feet, the ankle muscle strength changes depending on it.

“…O pé desempenha dupla função na fase de apoio durante a corrida, ele atua absorvendo choques e impactos durante o apoio do calcanhar no solo, e adaptando-se as irregularidades do terreno. Também, funciona como alavanca para gerar força de impulso dos membros inferiores para a corrida 18 .…”

“…As entorses em inversão são mais comuns, comparadas com a em eversão, e frequentemente ocasiona lesões nos ligamentos laterais. O ligamento talofibular anterior, dentre os três ligamentos laterais é o mais fraco, ele possui a função de impedir que aconteça uma subluxação anterior do tálus, e na posição de inversão, flexão plantar e rotação medial, ele é lesionado 18 .…”

RESUMOMuitos indivíduos aderiram a corrida de rua nos últimos tempos, por se tratar de um esporte de fácil adaptação, contudo alguns corredores não realizam o treinamento correto ou estão sujeitos a uma preparação física inadequada. Pela corrida ser um esporte de alta intensidade, o treinamento incorreto pode acarretar sérias lesões desportivas, como por exemplo, a entorse lateral de tornozelo, a mais frequente dentre as lesões, ocasionada na maioria das vezes devido a uma inversão do pé após um movimento repentino. Os exercícios excêntricos podem ser considerados uma alternativa dentro da fisioterapia preventiva capaz de auxiliar na prevenção de entorse de tornozelo durante a corrida, pois proporcionam o aumento de força e potencializam uma maior estabilidade articular do tornozelo. Neste sentido, o objetivo desta revisão foi buscar e verificar na literatura estudos que comprovem os resultados do treinamento excêntrico como forma de prevenção de possíveis entorses de tornozelo em corredores de rua.Palavras-Chave: Entorse de tornozelo.

During fatigued conditions, badminton players may experience adverse effects on their ankle joints during smash landings. In addition, the risk of ankle injury may vary with different landing strategies. This study aimed to investigate the influence of sport-specific fatigue factors and two backhand smash actions on ankle biomechanical indices. Thirteen female badminton players (age: 21.2 ± 1.9 years; height: 167.1 ± 4.1 cm; weight: 57.3 ± 5.1 kg; BMI: 20.54 ± 1.57 kg/m2) participated in this study. An 8-camera Vicon motion capture system and three Kistler force platforms were used to collect kinematic and kinetic data before and after fatigue for backhand rear-court jump smash (BRJS) and backhand lateral jump smash (BLJS). A 2 × 2 repeated measures analysis of variance was employed to analyze the effects of these smash landing actions and fatigue factors on ankle biomechanical parameters. Fatigue significantly affected the ankle-joint plantarflexion and inversion angles at the initial contact (IC) phase (p < 0.05), with both angles increasing substantially post-fatigue. From a kinetic perspective, fatigue considerably influenced the peak plantarflexion and peak inversion moments at the ankle joint, which resulted in a decrease the former and an increase in the latter after fatigue. The two smash landing actions demonstrated different landing strategies, and significant main effects were observed on the ankle plantarflexion angle, inversion angle, peak dorsiflexion/plantarflexion moment, peak inversion/eversion moment, and peak internal rotation moment (p < 0.05). The BLJS landing had a much greater landing inversion angle, peak inversion moment, and peak internal rotation moment compared with BRJS landing. The interaction effects of fatigue and smash actions significantly affected the muscle force of the peroneus longus (PL), with a more pronounced decrease in the force of the PL muscle post-fatigue in the BLJS action(post-hoc < 0.05). This study demonstrated that fatigue and smash actions, specifically BRJS and BLJS, significantly affect ankle biomechanical parameters. After fatigue, both actions showed a notable increase in IC plantarflexion and inversion angles and peak inversion moments, which may elevate the risk of lateral ankle sprains. Compared with BRJS, BLJS poses a higher risk of lateral ankle sprains after fatigue.
