Isokinetic profile of Elite Serbian female judoists

Elite judo athletes undergo vigorous training to achieve outstanding results. In pursuit of achieving competitive success, the occurrence of injuries amongst judo athletes is not rare. The study aimed to perform a knee flexors and extensors isokinetic torque analysis in elite female judo athletes. Fifty\u2010eight elite female judo athletes of the Serbian national team (21.02 \ub1 3.11 years; 62.36 \ub1 11.91 kg, 165.04 \ub1 10.24 cm, training experience 12.72 \ub1 2.98 years) volunteered to participate in this study. The range of motion (ROM) was set at 90\u2070. Testing was performed in a concentric\u2013concentric mode for the testing speed of 60 \u2070/s. Five maximal voluntary contractions of knee extensors and knee flexors muscle groups were measured for both legs. The obtained data showed a statistically significant difference in absolute torque values among different categories as heavier athletes demonstrated higher values. Post hoc analysis showed a significant difference between weight categories, as heavier athletes demonstrated higher values, while no significant differences in normalized torque values for different weight categories were observed. The implementation of new elements and training modalities may improve performance and prevent lateral asymmetry, thus reducing the risk of injury

Cardiac response to Nage no Kata in judo

The first world judo Kata competition was held in October 2007 in Tokyo, Japan. The Nage no Kata was developed in 1884 and 1885 at the Kodokan. by Jigoro Kano, the founder of judo, who developed Kata to demonstrate the principles of judo and to provide a type of training which emphasized performing techniques under controlled setting. According to Kano, to fully develop judo skills, it is essential to involve both Randori and Kata techniques [1]. Most highgrade Japanese judo teachers emphasize the importance of Kata performance for judokas’ development, in particular Nage no Kata [2]. Results of the study conducted by Canestri et al. [3] suggested that session-RPE and HR monitoring is a simple and practical tool to quantify training loads in judo in different conditions. To date, no studies have investigated on possible association between HR and RPE related to Nage no Kata in judo athletes. Also, empirical evidence shows no studies that have researched correlation between Tori and Uke in any segment of judo performance. Thus, the aim of this study was to analyse the changes in HR and RPE of male and female judo athletes who performed Nage no Kata in a competitive setting
