The aim of this study was to investigate the effects of different swimming race constraints on the evolution of turn parameters. One hundred and fifty-eight national and regional level 200-m (meters) male swimming performances were video-analyzed using the individualized-distance model in the Open Comunidad de Madrid tournament. Turn (p<.001, ES=0.36) and underwater distances (p<.001, ES=0.38) ...

THE PREVALENCE OF INJURY PREVENTION PROGRAMS CONTINUES TO INCREASE, BUT THE INJURY RATES REMAIN CONSTANT. THESE PROGRAMS USE A BLOCK PRACTICE SCHEDULE AND CLOSED-SKILL EXERCISES, BUT GAMES ARE RANDOM AND INVOLVE OPEN SKILLS. TO IMPROVE THE EFFICACY OF THE NEUROMUSCULAR TRAINING PROGRAMS AND TREND THE INJURY RATE DOWNWARD, THESE PROGRAMS SHOULD INCORPORATE MOTOR LEARNING THEORY. BY INCORPORATING...

Deficits in emotion regulation have been identified as an important risk and maintaining factor for depression. The aim of this study was to examine the long-term effects of emotion regulation on symptoms of depression. Moreover, we investigated which specific emotion regulation skills were associated with subsequent symptoms of depression. Participants were 116 individuals (78% women, average ...

Observable structure of variability presents a window into the underlying processes of skill acquisition, especially when the task affords a manifold of solutions to the desired task result. This study examined skill acquisition by analyzing variability in both its distributional and temporal structure. Using a virtual throwing task, data distributions were analyzed by the Tolerance, Noise, Cov...

BACKGROUND Studies demonstrate that both doctors and patients may use adrenaline auto-injector improperly and the usage skills are improved by training. In this study, we aimed to determine the appropriate frequency of training to maintain skills for adrenaline auto-injector use. METHODS We invited all interns of 2011-2012 training period. At baseline, all participants were given theoretical ...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

During the last two decades, the labour demand structure in Germany and other OECD countries has experienced a decrease in the demand for low skilled and a rise in the demand for highly skilled employees. The adoption of modern technologies in the production process as well as the growth of international trade are often regarded as the main driving factors behind this change. On the other hand,...

We introduce skill chaining, a skill discovery method for reinforcement learning agents in continuous domains. Skill chaining produces chains of skills leading to an end-of-task reward. We demonstrate experimentally that skill chaining is able to create appropriate skills in a challenging continuous domain and that doing so results in performance gains.
