BACKGROUND: Data obtained on an isokinetic dynamometer are useful to characterize muscle status and have been reported in muscle imbalance studies in different types of sport. However, few studies have assessed elite handball players to establish reference values. OBJECTIVE: The purpose of this study was to compare, for the dominant (D) and non-dominant (ND) side, the isokinetic profile of shoulder rotator muscle strength between male handball players (H) and asymptomatic non-athletes (NA). METHOD: Isokinetic concentric and eccentric strength tests for D upper limbs were performed by the H group (n=20) and the NA group (n=12). Internal and external rotator muscle peak torque in concentric action was assessed at 60°/s and 300°/s and in eccentric action at 300°/s. We also calculated conventional balance (the ratio of external rotator peak torque to internal rotator peak torque in concentric action) and functional balance (the ratio of external rotator peak torque in eccentric action to internal rotator peak torque in concentric action). RESULTS: In the H group, dominant limbs were stronger in concentric action for external rotation at 60 and 300°/s. The conventional balance ratio for the D side was significantly lower at 60 and 300°/s for H compared to NA. The functional ratio for the D side was significantly lower at 300º/s for H compared to NA. CONCLUSIONS: Compared to asymptomatic non-athletes, handball players presented significant muscular imbalance resulting from daily sports practice, a known risk factor for shoulder injuries.

INTRODUÇÃO: Pessoas com epilepsia tem sido constantemente desaconselhadas a participarem de atividades físicas ou esportivas por receio do exercício provocar crises epilépticas. Apesar da atitude médica atual recomendando a participação em atividades esportivas, o estigma ainda persiste e as pessoas com epilepsia continuam menos ativas que a população em geral. OBJETIVOS: Neste sentido, vários estudos clínicos e experimentais têm demonstrado um efeito benéfico do exercício físico na epilepsia. O judô é um esporte tradicional e popular e pessoas com epilepsia freqüentemente perguntam aos médicos se podem participar deste tipo de esporte. CONCLUSÃO: Baseado nestas questões, este artigo de revisão propõe avaliar os riscos e benefícios da atividade física em pessoas com epilepsia e discutir o papel do judô neste contexto.

INTRODUCTION: Persons with epilepsy have previously been discouraged from participation in physical activity and sports for fear of inducing seizures or increasing seizure frequency. Despite a shift in medical recommendations toward encouraging rather than restricting participation, the stigma remains and persons with epilepsy continue to be less active than the general population. OBJECTIVES: In these lines, several clinical and experimental studies have demonstrated a positive effect of physical exercise on epilepsy. Judo is a traditional and popular sport and people with epilepsy often ask physicians whether they may engage in this sport. CONCLUSIONS: Based on this, our review article is designed to show the risks and benefits of physical activity in patients with epilepsy and discusses the role of judo in this context.
