Influence of upright versus time trial cycling position on determination of critical power and W′ in trained cyclists

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP.  相似文献

Contextual Barriers to School Reform in Spain     

Arco-Tirado  José L.  Fernández-Balboa  Juan-Miguel 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2003,49(6):585-600

Over the past two decades, the Spanish educational system has undergone various legal reforms. However, judging by the low educational performance of Spanish students as reported by the OECD for the year 2001, it seems that additional reforms are necessary. Several factors may account for the failure of previous reforms to attain the desired results. These include: (a) educators' low expectations that further reforms will succeed, (b) lack of financial resources, (c) institutional lack of commitment to implement the structural and administrative changes called for and (d) the adoption of questionable theoretical models for making appropriate structural, curricular and educational decisions. This essay presents some suggestions for implementing a reform program that would bring about substantial changes in these areas.  相似文献   

Blind spot detection using vision for automotive applications     

José BARRIGA 《浙江大学学报(A卷英文版)》2008,9(10):1369-1372

This paper describes a vision-based system for blind spot detection （BSD） in intelligent vehicle applications. A camera is mounted in the lateral mirror of a car with the intention of visually detecting cars that are located in the so-called blind spot and cannot be perceived by the vehicle driver. The detection of cars in the blind spot is carried out using computer vision techniques, based on optical flow and a double-stage data clustering technique for robust vehicle detection.  相似文献   

Key values of a Dutch cooperation school and the practice of religious education     

Erik Renkema  André Mulder  Marcel Barnard 《British Journal of Religious Education》2019,41(3):337-351

This article presents the results of a single case study from a cooperation school in the Netherlands. A cooperation school is the result of a merger between a public and a denominational school. Pupils from secular and religious backgrounds meet in the classroom. This religious diversity in this school is explored by an empirical research study. The research question was how key values of the school and of its teachers are exerted in religious education. Content analysis of interviews and videos of the ‘moment of contemplation’ show that there is a discrepancy between the school values and the practice of this moment. Conclusions concerning a social and a substantive perspective are drawn in the light of theoretical insight concerning diversity in religious education.  相似文献
