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

Trials, a specialty of mountain biking, differ a lot from other cycling specialties, because in addition to pedaling, they require jumping techniques to overcome obstacles that involve the whole body. In this sport, more than in others, the evaluation of technical movements using optoelectronic systems goes far beyond simply assessing the biomechanics of pedaling or the correct positioning on the bike. Starting from a previous study conducted with video analysis technique applied to the lateral jumping technique, two versions of this technique were compared, considering the kinematics of the act, taking into account both the data relating the subject and the bicycle. The joint angles of the lower limbs and the angles described by the bicycle on the three space plane were considered. The major differences have been found in the ＂leap over＂ phase, about the bending of the lower limbs and the angles described by the bicycle.展开更多

The specific training required from early years may cause some changes compared to the normal human anatomy and physiology. The aim of this study was to investigate the potential of motion analysis technologies for the evaluation of frequent changes in biomechanics of posture and dance. This paper presents an overview of the literature on the main postural compensation employed by the dancer; more specifically on the training effect of the fundamental basic techniques in ballet. It then focuses on the characteristics and potential of motion analysis technologies for the biomechanical evaluation of the dancer. The technologies investigated in this study are the optoelectronic system of gait analysis, which is one of the most advanced technologies for multifactorial motion analysis, integrated with the use of the force platform and the electromyography. These technologies enable a quantitative three-dimensional integrated multifactorial motion analysis in relation to kinematics and dynamics. Through specific systems of motion analysis, the instrumental analysis can describe objectively and with reasonable accuracy the biomechanics, the postural compensation, and the gait of the dancer.展开更多
