Injuries to the foot and ankle are common in elite athletes and may be responsible for prolonged periods of absence from competitive activity. The osseous, articular, ligamentous and tendinous structures of the foot and ankle may be injured in isolation or, more commonly, in combination. Various impingement syndromes of the ankle are described, many of which have characteristic features on imaging...
It is not easy to master reversal motion by himself / herself, because reversal motion uses different muscles that were not used in the dominant motion, and the reversal motion tend to be awkward. Dominant motion means the motion that a learner can play sports naturally with. In this background, we propose reversal motion skill self-learning environment that shows advice based on learner's dominant...
In this paper, we propose two methods to quantitatively analyze the motor skill in sports. The first method is the dimensionality reduction using the principal component analysis (PCA). The motion data, e.g. the joint angles (143-dimensional vector) or the muscle tensions (989-dimensional vector), are projected to a lower dimensional space that well represents the characteristics of original data...
The methods presented in this paper aim at detecting and recognizing players on a sport-field, based on a distributed set of loosely synchronized cameras. Detection assumes player verticality, and sums the cumulative projection of the multiple views' foreground activity masks on a set of planes that are parallel to the ground plane. After summation, large projection values indicate the position of...
The injuries in the lower limbs are common at the sports, and one of the most common injuries is ankle sprain. Kinesio taping is one of the useful treatments of ankle sprain. The objective of this study is to investigate the biomechanical effects of ankle Kinesio taping on ground impacts during the landing of vertical jump, and the effect of ankle Kinesio taping on vertical jump in functional instability...
