Technique in this sport has a great importance, since it reduces the risk of committing penalties and allows more efficient execution of the gesture. To improve technique, the motion analysis allows to study the gesture both qualitatively and quantitatively. In this work video analysis was used to study the side hop from rear wheel technique. Two different executions of this technique were analyzed. The primary purpose is the identification of the phases that make up the technical gesture. It was given an explanation to the movement strategies adopted in the execution of the jump in the two different situations.展开更多

Both in the clinical field and in rehabilitation, gait analysis is useful to evaluate the parameters that are modified following the administration of a protocol of adapted physical activity （APA）. Gait parameters could be measured using traditional rating scales, such as the Short Physical Performance Battery （SPPB） and technologies as a support to provide an assessment of gait quality. The aim of this study is to increase the objectivity of gait data obtained before and after a targeted APA program for a group of elderly people by integrating the traditional SPPB rating scale with the G Walk digital system. The former is an assessment tool to evaluate the functioning of lower extremity, in terms of chair stand, walk, and standing balance; whereas the latter can objectively evaluate the parameters of the gait. The sample was composed of I 1 adults aged between 67 and 94 years. The participants were chosen on the basis of a number of tests carried out to analyze their levels of autonomy, intellectual capacities and motor functioning. It has planned a six months APA protocol： before and after it, SPPB and G-Walk were administered. The results showed that space-time characteristics generally improve after APA intervention; therefore, the use of technology is a useful support for the evaluation scales.展开更多
