AbstractThis essay reads two differing conceptions of subjectivity in Frantz Fanon's work as corresponding to a shift in subjective orientation in certain moments of crisis, from what I term a unified individual – the subject of psychoanalysis – to a dispersed subject, the frenzied participant in collective activity. I believe that such a potential duality within the subject is best adopted when analysing Fanon's oeuvre, as well as when examining a subject's behaviour as participant in forms of unstructured collective protest such as rioting. Whereas the unified subject of psychoanalysis best expresses the consciously self-reflective individual in society, the dispersed subject expresses a subjectivity operating in excess of individualism. This dispersed subject acts collectively, as an object moving in tandem with other objects, without individual reflection. I argue that this shift comprises the initial spark of insurrection suggested in Fanon's work, the moment in which he sees the people pitched ‘in a single direction, from which there is no turning back’; and what Jean-Paul Sartre calls the explosive moment of ‘conflagration’. The two subject positions between which the subject shifts exist as two potential sides of every subject and comprise the ‘Manichean’ world in which Fanon's subject is entrenched. 相似文献

Abstract The purpose of the present study was to assess the effectiveness of the triad components (amenorrhoea, disordered eating, and osteoporosis) in identifying physically active women at risk of long-term health problems. Eighty-two females (mean age 31.1 years, s = 6.7; body mass 58.4 kg, s = 6.6; stature 1.65 m, s = 0.06) completed training, menstrual, and dietary questionnaires. Bone mineral density and size-adjusted bone mineral density were assessed at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. Seventy-eight percent of participants were eumenorrhoeic, 20% were oligomenorrhoeic, and 2% were amenorrhoeic. Thirty-six percent and 55% reported disordered eating practices in the present and past respectively. Eighty-one percent, 17%, and 2% were classified as normal, osteopaenic, and osteoporotic at the femoral neck respectively; 92% were normal, 7% osteopaenic, and 1% osteoporotic at the lumbar spine. No significant differences in femoral neck size-adjusted bone mineral density were observed between eumenorrhoeic and oligo/amenorrhoeic participants (F 2,80 = 0.119, P = 0.73); eumenorrhoeic participants had significantly greater lumbar spine size-adjusted bone mineral density (F 2,80 = 9.79, P = 0.003). Disordered eating participants had significantly lower femoral neck size-adjusted bone mineral density than those reporting no disordered eating (F 2,80 = 13.816, P = 0.000). Twenty-two percent of participants fulfilled triad criteria, while 55% were “at risk” of long-term health problems. An accumulation of conditions resulted in lower lumbar spine size-adjusted bone mineral density (F 1,80 = 6.074, P = 0.004). The current triad components do not identify all women “at risk” and more appropriate criteria such as exercise-related menstrual alterations, disordered eating, and osteopaenia are suggested. 相似文献

The purpose of this study was to examine African American toddlers' cortisol response to acute physical play activity within a full-time subsidized day care environment. Saliva samples were taken from participants (N = 22, ages 26–45.5 months) before and after physical play and control play conditions at the same time of day. ActiheartTM monitors were used to estimate the intensity of the play conditions. Although heart rate and other indicators were significantly higher during physical play, no change in cortisol levels was seen pre- to postphysical play. Further research is needed to better understand the cortisol response observed. 相似文献

There is evidence from previous cross-sectional studies that high volumes of certain sports, including running, swimming and cycling, may have a negative impact on bone mineral density. The aim of the present study was to evaluate prospectively the effects of high athletic training in individuals who engage in high volumes of all three of these activities (triathletes). Bone mineral density for the total body, arms and legs was determined by dual-energy X-ray absorptiometry in 21 competitive triathletes (9 men, 12 women) at the beginning of the training season and 24 weeks later. Age, body mass index, calcium intake and training volume were also recorded to examine potential mediators of bone mineral density change. Men had greater bone mineral density at all sites than women. No significant changes were observed over the 24 weeks for either total body or leg bone mineral density. Bone mineral density in both arms increased by approximately 2% in men ( P ? 0.03), but no change was observed for women. Change in bone mineral density at all sites was unrelated to age, body mass index, calcium intake and training volume. The results suggest that adverse changes in bone mineral density do not occur over the course of 6 months of training in competitive triathletes. 相似文献

Physical education teachers and the programs that prepare them find themselves in the early part of the 21st century in a public policy environment that differs significantly from that of the 20th century. This policy environment is grounded in an ideology that postulates that schools and teachers, rather than social forces, should be held responsible for academic outcomes, and in turn, economic success. For the first time, physical education teachers are being held accountable for student learning in the same way as their classroom peers. Improving the effectiveness of teachers is seen as the primary mechanism for improving student learning. In discussing how teaching effectiveness has evolved, I describe a relationship among the process–product paradigm, the ecological paradigm, and a neo-ecological paradigm called the instructional core. The latter paradigm extends our understanding of teaching effectiveness in new ways by describing the dynamic and interdependent relationship among teacher, student, and content in the gymnasium. It has significant implications for the professional development of teachers and the conduct of teaching effectiveness research. I conclude by discussing why content is so critical to conceptions of teaching effectiveness. 相似文献

ABSTRACTAthlete adherence to nutritional guidance is critical for optimal health and performance, yet little is known about the barriers and enablers to athletes’ dietary behaviours within high-performance sport. To advance understanding, we applied a theoretical lens derived from the Capability, Opportunity, Motivation – Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to explore the qualitative accounts of sports nutritionists. Five focus groups comprising sports nutritionists working in Olympic and Paralympic sport (n = 14), professional sport (n = 6), or both (n = 6) were undertaken. Thematic analysis was conducted and the interpretations of the findings were guided by COM-B and the TDF. To achieve nutritional adherence, the behavioural analysis identified the need to intervene across all three COM-B components and at least five associated TDF domains (e.g., decision-making processes, reinforcement, social influences, behavioural regulation and environmental context and resource). For the first time, the findings illustrate the complex interplay of the training setting with the capabilities, opportunities, and motivation of the practitioners, athletes and coaches. By applying established behavioural science theories to sports nutrition, the foundations for the development of targeted and multifaceted behavioural interventions addressing athlete dietary adherence in high-performance sport have been laid. 相似文献

Purpose The purposes of this study were to: (a) examine the effect of experience and goal constraints (speed, accuracy) on kicking patterns; (b) determine if effective striking mass was independent of ankle velocity at impact; and (c) determine the accuracy of kicks relative to independent factors. Method Twenty participants were recruited to kick at 3 different velocities with and without an accuracy requirement. Multivariate analysis of variance determined if relative timing of joint angular velocities changed during the kick. Chi-square analysis determined if calculated effective mass was independent of ankle velocity at impact. Analysis of variance (ANOVA) was used to examine differences in absolute constant error and variable error according to independent factors. Results Results indicated that experience and speed affect absolute timing of joint velocities with no changes in the relative timing of peak joint velocity across independent factors. Chi-square analysis indicated that calculated effective mass is not independent of ankle velocity. ANOVA indicated that experienced performers displayed less variability error than did inexperienced performers. Conclusion It was concluded that: (a) Experience, velocity, and accuracy do not affect the relative timing of kicks; (b) kickers trade ankle velocity at impact for greater effective striking mass and ball velocity; and (c) variability in ball placement is affected by experience. 相似文献

The intention of this contribution is to show that training and doping in competitive sports may be considered as two implementations of economic paradoxes of concurrence. They are based on the interaction of the gladiator principle and a tribune effect. According to this terminology, training is related to the classical paradox whereas doping is related to Marx’s paradox (Stützel, 1979, Paradoxa der Geld- und Konkurrenzwirtschaft. Aalen: Scientia; Grass & Stützel, 1983, Volkswirtschaftslehre. München: Vahlen). In the paper, against this background, training and doping in elite sports are evaluated concerning their efficiency and fairness. As a result highly commercialized elite sports with an extreme win orientation turns out to be problematic. 相似文献

The aim of the study was to examine the effects of three different training models on aerobic power and body composition in recreationally active runners. According to their preferences 54 subjects (female=?27, male?=?27) were assigned to the following groups: (a) weekend group (WE), who performed two sessions of continuous endurance training weekly, (b) after-work group (FE) who carried out four sessions of high intensity training as well as an additional endurance run and (c) STAR group (STAR), who took part in a training with exercise telemetry monitors based on the heart rate variability. Over the 12-week study period the mean training volume was approximately 2 h 15 min per week. Of the participants 47 successfully completed the training study and all 3 groups showed significantly improved aerobic power (p?<0.001); however, the FE group (d?=?1.15) showed increased VO2max superior to WE (d?=?0.48) and STAR (d?=?0.66) groups. Significant improvements in body mass (p?<?0.001), body fat (p?<?0.001) and visceral fat (p?<?0.001) were found in the WE, FE and STAR group. All groups completed the half marathon with no significant differences in performance. Based on a similar training volume, short, intensive endurance training sessions of about 30 min were found to elicit the greatest improvements of VO2max in recreationally active runners. 相似文献
