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

Should we easily wail about the embarrassment and the unfairness of life?Or should we accept obstacles as challenges?With a choice of stance we can allow ourselves to be oppressed victims.When anything happens to us,we can take it as a sign that we should not expect anything good out of our lives.These are times when we need to determine whether it is wisdom or fear that motivates us in our choices.…… 相似文献

This paper is concerned with the reconstruction, at the departmental level, of a university assessment policy that required a shift from norm-referenced assessment to criterion-referenced assessment (CRA). As such, it provides an account of a change process driven by a centralised policy imperative and yet implemented and driven also from a bottom-up process. A wide range of data was gathered using action research methods. Individual and focus group interviews were conducted with staff and students, participant journals were kept and successive drafts of criteria and standards, and samples of students' responses were collected. The data suggested that a top-down policy can be successfully combined with a departmental-driven process, if financial and time considerations are addressed and a collaborative process amongst staff is sustained. The use of action learning, as a tool for change, appeared to assist participants to begin to own a top-down policy. 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
