ABSTRACT

The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists.  相似文献

Starting the data conversation: informing data services at an academic health sciences library     

Kevin B. Read  Alisa Surkis  Catherine Larson  Aileen McCrillis  Alice Graff  Joey Nicholson  Juanchan Xu 《Journal of the Medical Library Association》2015,103(3):131-135

Objective

The research obtained information to plan data-related products and services.

Methods

Biomedical researchers in an academic medical center were selected using purposive sampling and interviewed using open-ended questions based on a literature review. Interviews were conducted until saturation was achieved.

Results

Interview responses informed library planners about researchers’ key data issues.

Conclusions

This approach proved valuable for planning data management products and services and raising library visibility among clients in the research data realm.  相似文献

Sense of Place in Child Care Environments     

Marilyn A. Read 《Early Childhood Education Journal》2007,34(6):387-392

The exterior design of existing preschool environments is evaluated in the context of contemporary writings by architects focusing on creating designs that nurture children’s emotions. Sense of place research is discussed in relation to young children’s experiences. Findings reveal that the majority of sites included in the study incorporated many physical design elements that create a sense of place for children in preschool environments, including small-scale structures, windows, landscaping, natural wall materials, and thresholds. Recommendations for administrators and directors planning and designing a new or remodeled preschool environment include incorporating features that reflect home-like environments with windows, thresholds, and landscaping.  相似文献

Injury prevention in male youth soccer: Current practices and perceptions of practitioners working at elite English academies     

Paul J. Read  Pablo Jimenez  Jon L. Oliver  Rhodri S. Lloyd 《Journal of sports sciences》2018,36(12):1423-1431

Forty-one practitioners inclusive of physiotherapists, sports scientists and strength and conditioning coaches from the academies of elite soccer clubs in the United Kingdom completed an on-line questionnaire which examined their: (1) background information; (2) perceptions of injury occurrence and risk factors; (3) screening and return to play; and (4) approach to designing and delivering injury prevention programmes with a response rate of 55% (41/75). Contact injuries were the most common mechanism reported and players between 13–16 years of age were perceived to be at the greatest risk. Pertinent risk factors included: reduced lower limb and eccentric hamstring strength, proprioception, muscle imbalances, and under developed foundational movement skills. Joint range of motion, jump tests, the functional movement screen, overhead and single leg squats were the most utilised screening methods. Training modalities rated in order of importance included: resistance training, flexibility development, agility, plyometrics and balance training. Training frequency was most commonly once or twice per week, during warm-ups, independent sessions or a combination of both. Injury prevention strategies in this cohort appear to be logical; however, the classification of injury occurrence and application of screening tools to identify “at risk” players do not align with existing research. The frequency and type of training used may also be insufficient to elicit an appropriate stimulus to address pertinent risk factors based on current recommendations.  相似文献   

The submergence and re-emergence of gender in undergraduate accounts of university experience     

Becky Francis  Penny Burke  Barbara Read 《Gender and education》2014,26(1):1-17

Gender distinction has been shown to characterise both undergraduate experiences and outcomes. Yet research recounted in this article supports work that shows that young people are often unaware of such trends, subscribing instead to individualist perspectives that foreground equality of opportunity and agency. This article examines the gender continuities and divergences in 64 undergraduate students' accounts of their experiences, and constructions of peers and lecturers, in higher education. Concepts of heteroglossia and monoglossia are applied to gender to explain how students submerged ‘structure’ and inequality in their accounts, but how discourses that presented the genders as distinct (and in which the masculine is elevated over the feminine) nevertheless ‘bubbled up’ in their articulations. The students tended to reject the notion that gender and other structural differences impact their experiences and outcomes; yet their broader discussions frequently reflected (often stereotypical) monoglossic constructions of gender difference. The article concludes with a discussion of the implications of these findings for the sociology of education and for higher-education pedagogy.  相似文献   

Mates or Married? Implications of Gender Composition and Physical Intimacy on Evaluation of Images Tested for Advertising     

Glenna L. Read  Isaiah J. Innis  Irene I. van Driel  Robert F. Potter 《Communication Research Reports》2013,30(3):220-230

Drawing upon the theoretical framework of social identity theory and literature on physical intimacy, consumer neuroscience, and social cognitive and affective neuroscience, responses to images featuring same-gender and other-gender pairs are explored through examination of self-reported attitudes and neural activity associated with attention, memory, and emotion. Under the pretense of pretesting the effectiveness of images to be used in a national advertising campaign, participants viewed still images while neuroelectric brain responses were recorded. Each image featured two women, two men, or a man and a woman presented in positions of physical intimacy. Results indicated that event-related brain potentials (ERPs) associated with attention did not differ overall based on couple composition. However, ERPs associated with working memory and emotion were enhanced when processing images with two men. Preference for these images was reflected in self-reported attitudes.  相似文献
