Running for Freedom: The Politics of Long-Distance Running in Modern Fiction

This essay analyses the uses of running in contemporary fiction. It addresses the question of the literariness of running, and the ways in which literature enables us to articulate aspects of the sport such as its heroism or its relationship to the nation. It looks at a number of fictional texts, and focuses largely on two important works, ‘The Loneliness of the Long-Distance Runner’, Sillitoe's celebrated novella of 1958, and Jean Echenoz's novel, Running, published 50 years later. This essay examines the quality of running defined in literature, then looks at its traditional function of celebration of heroes, before closing on the freedom associated with running in such works.     

The (Re)Emergence of a Religio-Spiritual Self-Cultivation Focus in Asian Martial Arts Monographs Published in Spain (1906–2009)

This article presents one analytical theme emerging from a bibliometric and content analysis of an annotated bibliography, compiled by the first author, comprising 1564 Asian martial arts monographs published in Spain between 1906 and 2009. The analysis reveals that the use of Asian martial arts and religio-spiritual self-cultivation practices, while very old in their indigenous South East Asian context, only appeared in published texts in Spain from the 1960s and this theme has been increasingly written about in the last two decades. In our analytical discussion, we contextualise this shift from a socio-historical perspective, focusing on three aspects: first and second, how this shift in focus in Asian Martial Art publishing fits with the patterns of societal secularisation in Spain, the rise of the New Age movement and counter-cultural spiritualities across Western culture; third, we comment on how, from this broader socio-historical context, Asian martial arts were well placed to fill ‘cultural spaces’ created by these changes.     

Effect of target change during the simple attack in fencing

Abstract

The aim of this study was to test the effect that changing targets during a simple long lunge attack in fencing exerts on the temporal parameters of the reaction response, the execution speed, and the precision and the coordination of the movement pattern. Thirty fencers with more than 10 years of experience participated in this study. Two force platforms were used to record the horizontal components of the reaction forces and thereby to determine the beginning of the movement. A three-dimensional (3D) system recorded the spatial positions of the 9 markers situated on the fencer plus the epee, while a moving target was projected on a screen, enabling the control of the target change. The results indicated that when a target change is provoked the reaction time (RT), movement time (MT), and the time used in the acceleration phase of the centre of mass (CM) increases significantly with respect to the attack executed with a straight thrust. The speed and horizontal distance reached by the CM at the end of the acceleration phase (V_X(CM) and S_X(CM), respectively) significantly decreased, while the errors increased. However, the temporal sequence of the movement pattern did not appreciably change.     

Girls' and boys' perceptions of physical education teachers' feedback: Effects on performance and psychological responses

Abstract

In this study, we examined the perceptions of physical education (PE) teachers' feedback patterns with female and male high school students (n = 325). Eight physical education teachers (4 females and 4 males) were involved. We examined (a) whether teachers' feedback was perceived differently by boys and girls, and how the sex of the teacher influenced these perceptions, and (b) the effects of types of feedback (praise, no response-successful, encouragement, technical information, criticism, no response-unsuccessful, and teacher's invested time) on students' perceived competence, effort, enjoyment, and their PE performance. A multivariate analysis revealed an interaction between teacher and student gender on perceptions of teacher feedback. Hierarchical regression analyses highlighted that the perceived feedback significantly predicted students' perceptions of competence (ΔR ² = 0.088), effort (ΔR ² = 0.119), enjoyment (ΔR ² = 0.085), and their PE performance (ΔR ² = 0.039) after accounting for the gender of the students and teachers and the students' initial PE performance. The perceptions of praise and teachers' invested time were positively linked with the dependent variables, whereas encouragement and technical information and criticism were negatively linked. The findings are discussed in terms of teaching effectiveness and gender equity.     

Parallel assessment of nutrition and activity in athletes: Validation against doubly labelled water, 24-h urea excretion,and indirect calorimetry

Abstract

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal · day^?1). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g · kg^?1 · day^?1). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal · day^?1) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal · min^?1; cycling: r = 0.95, SEE = 1.4 kcal · min^?1). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.     

Exploring the relationship between hope and burnout in competitive sport

Abstract

Researchers have postulated that hope may be an important factor associated with burnout. Consistent with hope theory contentions, low-hope individuals may be susceptible to burnout because they are prone to experience goal blockage, frustration, and negative affect, all of which likely increase the risk of burnout. We examined the relationship between hope and athlete burnout among 178 competitive athletes (63 females and 115 males) aged 15–20 years. Hope was significantly and negatively correlated with all three burnout subscales: emotional/physical exhaustion, a reduced sense of accomplishment, and sport devaluation. Moreover, results of a multivariate analysis of variance showed that low-hope athletes scored significantly higher than medium- and high-hope athletes on all three burnout dimensions. Finally, results revealed that agency thinking was a significant predictor of all burnout dimensions. Frustration over unmet goals and a perceived lack of agency, a characteristic of low-hope athletes, might pose a risk factor in athlete burnout, whereas being able to maintain hope appears to be associated with health and well-being.     

Development and Validation of a Method for Determining Tridimensional Angular Displacements with Special Applications to Ice Hockey Motions

Abstract

Tridimensional angular displacements of the skates were determined with a single cinecamera used in conjunction with two orthogonal rods attached to the rear part of the skater's boots. The method was based on the commutative law with the imposed restrictions that two of the angles were small in relation to the other one, and that a sequence of angular displacements was defined. This approach required the sole determinations of the planar coordinates of the three points delimiting the orthogonal rods. An experimental setup was designed to validate the method: the criterion angles were approximated with less than 2 degrees of error. Subsequently, the method was applied to a practical situation: the two-legged stop in ice hockey. The combination of this tridimensional method with instrumented strain gauge skates for the measurement of forces provides a new and powerful tool for performing kinetic analyses in tridimensional skating activities.     

Situational Indexes of Achievement Motivation,Help-Seeking,and Performance: Influences of the Learning Context and Gender Differences

Abstract

Sixteen college athletes and non-athletes were given 10 30-sec. practice trials to learn how to balance on a stabilometer. The next day they were allowed three more trials alone and three trials before a group of spectators. The non-athletes were significantly better on two of the three trials performed in front of the spectators. They also performed better than the athletes throughout the ten practice trials, although the tenth and last trial approached but did not yield a significant difference at the .05 level.     

Stabilization and passification of distributed-order fractional linear systems using methods of preservation

This paper studies the stabilization and passification of a class of distributed-order linear time-invariant systems, by using methods of preservation in the frequency domain. Results about preservation of stability and passivity of classical linear time-invariant systems are extended to one more general family of matrix functions. Based on these results, a new approach to the problems of stabilization and passification of distributed-order linear time-invariant systems is presented. Also a result that extends the known techniques for pole placement of classical linear time-invariant systems to the new class of distributed-order linear time-invariant systems is given. Examples are given to show the validity of theoretical results.
