“…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 .…”

“…Na entorse grau II, ocorre o rompimento com separação das fibras do ligamento, promovendo a instabilidade da articulação de forma moderada, levando a dor moderada ou forte, edema e rigidez. A entorse de grau III, provoca o rompimento ligamentar completo, seguido de instabilidade articular, incapacidade de sustentação do peso, dor intensa e perda da função 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.

Background: Paralympic powerlifting (PP) is one of the sports modalities that uses strength training with high loads, causing various physiological responses resulting from hemodynamic adaptations. Objective: To evaluate hemodynamic responses after traditional (TT) and eccentric (ET) training sessions in PP athletes. Methods: Twelve national-level PP athletes, aged: (Mean ± SD) 30.8 ± 10.05 years; 70.0 ± 16.1 kg. In the intervention, five sets of five repetitions (5 × 5) of the bench press at 80% of 1 repetition maximum (1RM) were used; in the TT and in the ET, 5 × 5 of the bench press with a load in the eccentric phase of 110% and that in the concentric phase of 80% of 1RM were used. Results: Compared to baseline, heart rate was significantly elevated at various times in the ET, between before and 20 min after (p = 0.023), and 40 min after (p = 0.035), but decreased to baseline in 24 h (p = 0.043, η2p = 0.395). In addition, the product pressure rate in the ET had a decrease between the moments before and 60 min after (p = 0.042), and before and 24 h after (p = 0.043). A high effect on myocardial oxygen volume in ET at 24 h was found (p = 0.018; η2p = 0.393). Conclusions: One session of traditional and eccentric training methods can be effective in causing significant changes in the cardiovascular system in PP athletes.
