This study aimed to explore the strength of the force–velocity (F–V) relationship of lower limb muscles and the reliability of its parameters (maximum force [F0], slope [a], maximum velocity [V0], and maximum power [P0]). Twenty-three men were tested in two different jump types (squat and countermovement jump: SJ and CMJ), performed under two different loading conditions (free weight and Smith machine: Free and Smith) with 0, 17, 30, 45, 60, and 75?kg loads. The maximum and averaged values of F and V were obtained for the F–V relationship modelling. All F–V relationships were strong and linear independently whether observed from the averaged across the participants (r?≥?0.98) or individual data (r?=?0.94–0.98), while their parameters were generally highly reliable (F0 [CV: 4.85%, ICC: 0.87], V0 [CV: 6.10%, ICC: 0.82], a [CV: 10.5%, ICC: 0.81], and P0 [CV: 3.5%, ICC: 0.93]). Both the strength of the F–V relationships and the reliability of their parameters were significantly higher for (1) the CMJ over the SJ, (2) the Free over the Smith loading type, and (3) the maximum over the averaged F and V variables. In conclusion, although the F–V relationships obtained from all the jumps tested were linear and generally highly reliable, the less appropriate choice for testing the F–V relationship could be through the averaged F and V data obtained from the SJ performed either in a Free weight or in a Smith machine. Insubstantial differences exist among the other combinations tested. 相似文献

The aim of the study was twofold, namely (i) to determine the prevalence of symptoms of common mental disorders (CMDs) among current and retired professional football and handball players and (ii) to explore the relationship of psychosocial stressors with the outcome measures under study. A total of 1155 players were enrolled in an observational study based on a cross-sectional design. Questionnaires based on validated scales were set up and distributed among current and retired professional football and handball players by the Danish football and handball players’ union. In professional football, the highest prevalence (4 weeks) of symptoms of CMDs was 18% and 19% for anxiety/depression among current and retired players, respectively. In professional handball, the highest prevalence (4 weeks) of symptoms of CMDs was 26% and 16% for anxiety/depression among current and retired players, respectively. For both the current and retired professional football and handball players, a higher number of severe injuries and recent adverse life events (LE) were related to the presence of symptoms of CMD. Players exposed to severe injuries and/or recent adverse LE were 20–50% times more likely to report symptoms of CMD. The results suggest that it is possible to recognize the population of professional athletes that are more likely to develop symptoms of CMD. This could create the opportunity to intervene preventively on athletes that suffered from severe injury and/or recent adverse LE that could lead to a faster and safer recovery and psychological readiness to return to play. 相似文献

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point. 相似文献

This is the second of two articles by the same author arguing against the thesis that there was a conspiracy between the Byzantine emperors and Saladin, sultan of Egypt and Syria, against the crusader states and the Third Crusade in the 1180s. While the focus of the first article was primarily on the Latin sources, the present study shifts the focus to the Arabic primary material, hitherto largely neglected or inadequately treated by modern historians. Through a critical re-examination and re-interpretation of the Arabic sources, backed by the introduction and discussion of new Latin material when necessary, this article presents expanded arguments on the relations between the Byzantine Empire, the Sultanate of Konya and Saladin in the 1180s. The conclusions lend further support to the view that the Byzantine rulers and Saladin never concluded an alliance against the Latin settlers of Outremer and the Third Crusade. 相似文献

This paper examines ideas surrounding the presentation of the Muslim “other” in Latin writings of the early period of the Crusades. Using a case-study approach of the views of one chronicler, Walter the Chancellor, in his work Bella Antiochena, on one individual Muslim, Najm al-Dīn Il-Ghāzī, the paper studies aspects of the image of Il-Ghāzī, the reasons for them, how and why they develop throughout the chronicle, and whether, from the other information given in the chronicle, it would be possible to interpret the information in other ways. The conclusions reached demonstrate that the reason for the vitriol in Walter's presentation was his wish to justify the Crusades and suggest that the writers of Outremer started to develop their own cross-cultural responses to Islam, independent of mainstream European thought, because of their situation. 相似文献

The nurture approach is a form of educational intervention for children with social, emotional and behavioural difficulties (SEBD). Utilising a unique example of a state‐run, special ‘nurturing’ primary school, Corinne Syrnyk, of St Mary's University College, Calgary, presents a case study of the experience of being a ‘nurture teacher’ in this distinctive environment. Findings suggest that nurture teachers value their role and are fulfilled by the challenge it presents. Nurture teachers tended to define their role according to personal qualities and described experiential learning as tantamount to the training process. This study illustrates the holistic approach adopted by nurture teachers and sheds light on the distinguishing features and experiences of nurture teachers. Implications for best practice concerning the support and training of existing and potential nurture teachers are discussed. 相似文献

Schools are required to develop policies and practices in line with the principles of both partnership with parents and pupil participation. However, there is increasing recognition of the potential tensions that may exist between these two principles. This paper reports on a study that aimed to explore the question of how schools might develop their home–school relationships in ways that enhance rather than constrain pupil participation. It focuses on the perspectives of children aged 6 to 16 years (with and without special educational needs), parents and teachers concerning children's involvement in decision-making at home and at school, and their participation within the home–school relationship. The findings highlight the need for schools to develop a coherent view of what active participation means for children and a vocabulary to communicate about this not only with pupils and staff across the whole school, but also with parents. They demonstrate that there is scope for two-way support between parents and teachers in relation to the promotion of children's involvement in decision-making both at home and at school. Further, they illustrate the complex and evolving three-way partnership between parent–child–teacher that is central to the home–school relationship. While it is acknowledged that children may rightly wish to keep a distance between aspects of home and school life, it is argued that there is a need for schools to give explicit consideration to the place of pupil participation within the home–school relationship. 相似文献

Elementary and special education teachers and school counsellors currently provide support to children presenting learning disabilities and behavioural problems symptomatic of the more hidden diagnosis of complex trauma resulting from abuse or severe attachment disruption. Specific disorders such as attention deficit/hyperactivity disorder (AD/HD) may be diagnosed in such children, but not the aetiology of complex trauma, resulting in missing information in the development of remedial and behavioural interventions. The evolving field of trauma counselling provides important information to special education teachers and school counsellors who work with children who have experienced trauma. In this review article authors Linda O'Neill of the University of Northern British Columbia (UNBC), Francis Guenette who is a doctoral student at the University of Victoria and Andrew Kitchenham of the University of Northern British Columbia summarise attachment, neurobiological, and complex trauma research that can be used in school settings to understand better the needs of these children. They conclude by suggesting that teachers and school counsellors would benefit from training on the consequences of childhood trauma and attachment disruption to develop interventions that will be effective and to identify what types of behaviours children can control and those they cannot. 相似文献
