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...

This paper investigates the impact of an increase in life expectancy on level and distribution income presence skill heterogeneity automation. It shows analytically that induces replacement low-skilled workers by automation capital high-skilled workers. Moreover, it raises premium has ambiguous effect total income. A simulation exercise, based US data, as well inequality We consider redistribut...

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...

This paper tests for the production complementarity between firms’ access to high-quality intermediate inputs and their skill composition joint impact on output quality. Using census data at firm-product level Ecuador 1997–2007, we exploit exogenous tariff changes Ecuador’s entry World Trade Organization show that input cuts allow firms upgrade Next, demonstrate by means of within-firm instrume...
