This study aimed to evaluate the effect of simulated training strategies on performance potential in elite short-track speed skaters. Training load and field-based criterion performances from fifteen athletes (10 males, 5 females) were collected over a 3-month training period and the relationship between training loads and performance was computed with a variable dose-response model using a genetic algorithm. Individual simulations of tapers preceded or not preceded by an overload training (OT) were assessed. We obtained a significant correlation between actual and modelled performances (R2 = 0.76 ± 0.07). Regarding model parameters, no significant difference was found between males and females but the time to recover performance tended to be lower in females. Simulations in which the taper parameters were free highlighted that an exponential or a step taper were the most effective for increasing performance compared to a linear taper (p < 0.05). Optimal exponential taper duration after OT was 10.7 ± 2.4d and the optimal load reduction was 75.9 ± 3.7%. OT intensity had the greatest influence on the predicted performance, followed by OT duration, taper decay, and to a lesser extent load reduction during taper and taper duration. Thus, a variable dose-response systems model allows the evaluation of different taper strategies and their potential effect on performance changes. 相似文献

It has long been recognized in the nonverbal communication literature that individual differences in extraversion are expected to be most clearly evident in expressive forms of nonverbal behavior. Although several studies designed to examine the correlation between extraversion and nonverbal behavior have been conducted, most attempts to summarize these studies reflect the inconsistent nature of the research findings. Indeed, correlations range from ?.36 to .73. The extant literature summaries are limited to narrative reviews, however, which tend to be highly selective. The purpose of this study was to meta‐analyze the relevant studies. Results indicated that the mean correlation coefficient weighted for sample size was .13 for the entire sample of studies. Although 63% of the variance was attributable to sampling error, the distribution of correlations was heterogeneous. The remaining variance was due to two methodological artifacts: sample size and the number of nonverbal behaviors coded. For example, hierarchical breakdowns by moderator indicated that the mean correlation was .50 for highly focused studies—those in which researchers concentrated on a few behaviors and limited coding to 40 or fewer subjects. A cognitive‐overload model for these findings is offered and corroborated by findings from other research domains. Implications for communication research and theory are discussed. In addition to clarifying the empirical relationship between extraversion and nonverbal behavior, the contributions of this study reside, in part, in its implications for large samples and large numbers of nonverbal behaviors coded in research and for meta‐analyses of such research literatures. 相似文献

This study investigates the relationship between communication overload and uses of diverse communication channels in terms of their level of synchronicity. Emphasis on the synchronicity of any given channel reveals how temporal elements (i.e., rate and processing time) play an important role in perceptions of communication load. Additionally, this study examines the association between communication overload, organizational identification and job satisfaction. Findings reveal: (a) both high and low synchronous channels are associated with increased reports of communication overload; (b) a mediating effect of organizational identification on the relationship between communication overload and job satisfaction; and (c) a moderating effect of communication overload on the relationship between low synchronous channels and organizational identification. 相似文献

Drawing on the stressor-strain-outcome framework, this study investigates how information irrelevance and overload induce social network fatigue, and the relationship of these variables to users’ information avoidance behavior. It also examines the conditions under which social network fatigue is more likely to be translated into information avoidance behavior. The analysis of data collected from 341 users of WeChat Moments suggests that information irrelevance directly leads to information avoidance behavior, and social media fatigue as a mediator partially mediates the impact of information overload on information avoidance behavior and fully mediates the impact of social overload on information avoidance behavior. Furthermore, time pressure strengthens the effect of social network fatigue on information avoidance behavior. This study fulfills the identified need for an in-depth investigation of actual discontinuous behavior in social network services (SNSs) by investigating information avoidance behavior and its antecedents. The findings provide SNSs providers with guidelines on how to manage users’ behavior so that they remain active users of the SNSs. 相似文献

The management of email remains a major challenge for organisations. In this article, we explore the extent of the perceptions of email as a business critical tool within an organisation and how the level of such perceptions may moderate the level of email overload experienced by individuals within the organisation. Data from a sample of 1100 employees of a multinational technology firm are analysed using multivariate techniques. The results suggest that without a clearly stated code of email practice within an organisation, there are likely to be large variations in what is perceived as ‘business-critical’ email and, as a result, a substantial amount of email generated within the organisation may not be ‘business-critical’, potentially increasing the level of ‘email-overload’ experienced by individuals within the organisation. 相似文献
