This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F0), maximal horizontal power (Pmax), maximal ratio of horizontal force (RFpeak), decrease in the ratio of horizontal-to-total force (DRF), total force and maximal sprinting velocity (v0)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2nd-4th, 5th-7th and 8th-10th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v0 (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F0 (ES?=?–0.59). DRF moderately decreased (14%; ES=–0.76–1.11), and RFpeak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load. 相似文献

ABSTRACT We implemented an intergenerational (IG) summer program at a colocated site for 2 consecutive summers to maximize continuity and enhance sustainability. We incorporated multiple methods to represent the views of key program stakeholders, including staff and administrators, parents who attended the program, and facilitators’ reports of the experiences of child and adult participants. We generated a list of themes and subthemes from each source and triangulated the data points. Despite the resources invested and the challenges faced, the program was well received and viewed as beneficial. These findings offer insight into the likelihood of sustainability for IG summer programming. 相似文献

Longitudinal data are often collected in waves in which a participant’s data can be collected at different times within each wave, resulting in sampling-time variation that is unaccounted for when waves are treated as single time points. Little research has been reported on the effects of this temporal imprecision on longitudinal growth-curve modeling. This article describes the results of a simulation study into the effect of sampling-time variation on parameter estimation, model fit, and model comparison with an empirical validation of the model fit and comparison results. 相似文献

The presence of university students in the United States with disabilities is not a new phenomenon. However, little is known about the attitudes of university faculty concerning less visible disabilities such as attention‐deficit hyperactivity disorder (ADHD). Using a sample of faculty at a university in the United States (n = 136), the impact of age on faculty’s acceptance of ADHD was examined. Results indicated a higher percentage of older faculty members, compared with middle‐aged and younger faculty, selected ADHD as a condition worthy of special instructional accommodations. Irrespective of age of the respondents, ADHD had the lowest acceptance as a condition deserving special accommodations. Finally, fewer middle‐aged and older faculty attributed difficulties experienced by a student with ADHD symptoms to “bad” character, a lack of discipline or a lack of motivation. These findings suggest more emphasis should be placed on disability‐related education and training for faculty members during early stages of their careers. 相似文献

Characterising the impact performance of field hockey sticks 总被引:1,自引:1,他引:0
Published research on field hockey equipment is scarce. The aim of this research was to investigate methods for characterising the impact performance of field hockey sticks. Three sticks were used with fundamental frequencies in the range 74?C154?Hz. Striking an initially still ball with a stick was identified as the preferred method for characterising performance. Impacts were simulated at mean velocities of 19?m/s at toe and 16?m/s at the shaft. The mean apparent coefficient of restitution and standard deviation were ?0.32?±?0.05 at the toe and ?0.18?±?0.02 at the shaft. The foundation work presented here provides the foundations for developing a methodology for characterising the impact performance of field hockey sticks. 相似文献
