In this paper we demonstrate how interpretable temporal patterns can be discovered within raw EMG measurements collected from tests in professional In-Line Speed Skating. This representation of complex muscle coordination opens up new possibilities to optimize, manipulate, or imitate the movements. The discovered knowledge could be used in medicine (e.g. rehabilitation), sports (e.g. movement o...

OBJECTIVE To compare the distribution and observation of helmet use patterns among 4 common childhood leisure activities-bicycle riding, in-line skating, skateboarding, and scooter riding-in a setting with no helmet use legislation. DESIGN A cross-sectional, unobtrusive, direct observation of children engaged in 1 of the 4 activities was conducted during an 8-week period. SETTING Eight comm...

To gain a better understanding of push-off mechanics in speed skating, forward simulations were performed with a model comprising four body segments and six muscles. We started with a simulated maximum height one-legged jump, obtained by optimization of muscle stimulation time histories. The simulated jump was very similar to one-legged jumps produced by a human, indicating that the model was r...

Figure skaters are often young athletes involved in an extremely stressful, structured environment that is focused solely on skating. These athletes are at risk for a multitude of psychologic concerns, including poor communication skills, performance anxiety, stress, and family issues. Helping athletes develop self-awareness, techniques to control stress and anxiety, motivational strategies, ab...

purpose the aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in europe. methods we investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in europe, the ‘inline one-eleven’ over 111 km in switzerland,...
