International travel is an essential part of the life of elite athletes, both for competition and training. It is also becoming increasingly common among recreational sportspersons. Long-distance travel is associated with a group of transient negative effects, collectively referred to as 'travel fatigue', which result from anxiety about the journey, the change to an individual's daily routine, and dehydration due to time spent in the dry air of the aircraft cabin. Travel fatigue lasts for only a day or so, but for those who fly across several time zones, there are also the longer-lasting difficulties associated with 'jet lag'. The problems of jet lag can last for over a week if the flight crosses 10 time zones or more, and they can reduce performance and the motivation to train effectively. Knowledge of the properties of the body clock enables the cause of the difficulties to be understood (an unadjusted body clock), and forms the basis of using light in the new time zone to promote adjustment of the body clock. Sleep loss and its effects are important components of jet lag, and attempts to promote sleep by the use of melatonin and other hypnotics are also relevant. Sleep loss is also found in those who undertake challenges that involve long periods where the normal consolidated sleep of 8 h length is not possible. Advice on sleep regimens in such circumstances is given. 相似文献

The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., 1999) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n = 584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index = 0.92, Tucker-Lewis index = 0.88, root mean square error of approximation = 0.05) but minimal support for the training items (robust comparative fit index = 0.86, Tucker-Lewis index = 0.81, root mean square error of approximation = 0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required. 相似文献

This study examined the motivational profiles of elite youth athletes to determine whether individual differences in goal orientation corresponded with differential levels of imagery use. Two hundred ninety male (n = 88) and female (n = 202) young athletes (M = 16.6 years, SD = 1.48) completed the Perceptions of Success Questionnaire (POSQ, Roberts, Treasure, & Balague, 1998) to assess dispositional goal orientations and the Sport Imagery Questionnaire (Hall, Mack, Paivio, & Hausenblas, 1998) to assess frequency and function of imagery use. A two-stage cluster analysis on the POSQ scores revealed a three-cluster solution with a multivariate analysis of variance indicating significant differences among cluster groups in imagery use. Athletes in Cluster 3 (higher task/higher ego) used significantly more imagery, regardless of the function than athletes in Cluster 1 (lower task/moderate ego) or Cluster 2 (moderate task/lower ego). These findings are discussed with reference to the role of achievement motivation in influencing young athletes' behavioral investments in mental strategies. 相似文献

Although Curriculum 2000 includes some welcome changes, such as the inclusion of drama, it is essentially a missed opportunity. I argue that it fails to address the complexity of modern life. In many academic areas, including literature, issues of identity are central to fundamental debates. Such debates have been precipitated by increasing economic globalisation and the consequent increase in interdependence between people from diverse cultural heritages. Although this situation is not new, the social and technological changes of recent decades have altered the pace of such developments. In most cities school populations reflect such changes. In this paper I argue that there are substantial gaps in the curriculum which derive mainly from government policy being premised on crude and obsolete notions of English identity. Such notions lead to a confusion of the concepts of culture and citizenship as modes of belonging. In my view both of these factors severely constrain our ability to construct a critical curriculum which adequately addresses contemporary interests and dilemmas. 相似文献

Although research has established the long-term damaging effects of incest, these efforts have suffered from the lack of valid, standardized assessment instruments. The present study reports on the construction and factor validation of the Response to Childhood Incest Questionnaire (RCIQ), a self-report instrument that assesses a range of commonly reported symptoms experienced by adult survivors of incest. A clinical population of 104 adult women who had experienced childhood or adolescent incest completed the RCIQ. A factor analysis of the RCIQ items revealed seven factors which corresponded to hypothesized stress response themes experienced by survivors of traumatic events. These factors include vulnerability and isolation, fear and anxiety, anger and betrayal, reaction to the abuser, sadness and loss, and powerlessness. In addition, four factors corresponded to the diagnostic criteria for post-traumatic stress disorder: intrusive thoughts, avoidance and intrusive emotions, detachment, and emotional control and numbness. The usefulness of the RCIQ as a pre- and post-treatment measure and the need for further research is discussed. 相似文献
