Background: Much research and practice in the field of physical activity and physical education for girls has been trapped in a reproductive cycle of telling the ‘same old story’ as if it is news over and over again, since at least the 1980s. A thread running through this narrative is that despite all of this research and related interventions, we have yet to find the ‘solution’ to the ‘problem’ of girls and physical education. As a result, little progress appears to have been made in terms of changing things for the better for the majority of girls.Purpose: We offer an activist approach to work with girls in physical education as one possible means of breaking the reproductive cycle of research and media reporting that we suggest has worked against improving the situation for girls. We take a pragmatist stance to ask ‘can we make the situation for girls better than it is currently?’ and ‘how might we go about this task?’ We propose an activist approach not as ‘the solution’ to the ‘problem’ of girls in physical education, but as one worthy of testing in practice.Process: We begin by outlining the broad features of an activist approach to working with girls in physical education. We then overview the findings of a growing body of activist studies in physical education and identify four critical elements that we believe need to be present in order to assist girls to identify, name and negotiate barriers to their engagements with physical education and their participation in physically active lifestyles. We highlight one example of an activist study that shows how the four critical elements interact in their work with girls.Discussion: We argue for the need for a consensus around improving the current situation of girls in physical education, for a scaling up of this activist work as it is tested in practice, and for the coincidental development of a pedagogical model for working with girls in physical education. 相似文献

The purpose of this study was to quantify the inter-session reliability of force–velocity–power profiling and estimated maximal strength in youth. Thirty-six males (11–15 years old) performed a ballistic supine leg press test at five randomized loads (80%, 100%, 120%, 140%, and 160% body mass) on three separate occasions. Peak and mean force, power, velocity, and peak displacement were collected with a linear position transducer attached to the weight stack. Mean values at each load were used to calculate different regression lines and estimate maximal strength, force, velocity, and power. All variables were found reliable (change in the mean [CIM] = ? 1 to 14%; coefficient of variation [CV] = 3–18%; intraclass correlation coefficient [ICC] = 0.74–0.99), but were likely to benefit from a familiarization, apart from the unreliable maximal force/velocity ratio (CIM = 0–3%; CV = 23–25%; ICC = 0.35–0.54) and load at maximal power (CIM = ? 1 to 2%; CV = 10–13%; ICC = 0.26–0.61). Isoinertial force–velocity–power profiling and maximal strength in youth can be assessed after a familiarization session. Such profiling may provide valuable insight into neuromuscular capabilities during growth and maturation and may be used to monitor specific training adaptations. 相似文献
