Perfectionism and training distress in junior athletes: The mediating role of coping tendencies

Training distress occurs when athletes fail to cope with physiological and psychological stress and can be an early sign of overtraining syndrome. Recent research has found that perfectionism predicts increases in training distress in junior athletes over time. The current study provides the first empirical test of the possibility that coping tendencies mediate the perfectionism-training distress relationship. Adopting a cross-sectional design, 171 junior athletes (mean age?=?18.1 years) completed self-report measures of perfectionistic strivings, perfectionistic concerns, problem-focused coping, avoidant coping, and training distress. Structural equation modelling revealed that avoidant coping mediated the positive relationship between perfectionistic concerns and training distress, and mediated the negative relationship between perfectionistic strivings and training distress. Problem-focused coping did not mediate any relationships between dimensions of perfectionism and training distress. The findings suggest that the tendency to use coping strategies aimed at avoiding stress may partly explain the relationship between perfectionism and training distress but the tendency to use, or not use, problem-focussed coping does not.     

Adapting,correcting and sequencing movements: does working-memory capacity play a role?

Interest in the role of working-memory capacity in everyday abilities has recently extended to the acquisition of motor skills. This review article examines the role of working-memory capacity in two areas of motor skill acquisition: (1) adapting and correcting movements in response to errors, and (2) sequencing movement patterns. Across a number of studies it was evident that individuals with low or underdeveloped working-memory capacity experienced diminished learning when the practice contexts placed high demands on working memory. Verbal working-memory capacity was associated with the ability to correct movement errors, while several studies revealed the importance of spatial abilities, including spatial working-memory capacity, when learning movement adaptations. Visuo-spatial working-memory capacity correlated with movement sequence learning, either explicitly or implicitly, but old age affected this relationship. Despite these correlations, however, our understanding of the relationship between working-memory capacity and motor skill acquisition is clouded by inconsistent results and a reliance on correlational analyses. To extend understanding of the role of working-memory capacity in motor skill acquisition, researchers should seek to explore novel experimental paradigms that bear closer resemblance to everyday tasks.     

Education and Multimedia: the actions of the European Union

This paper sets out the findings and recommendations of a task force which was set up by the European Commission which investigated the “Educational Multimedia”. It illustrates some of the strategic planning which has taken place across EU member states to co‐ordinate work on new education technologies to enhance teaching and learning.     

The effects of prior incremental cycle exercise on the physiological responses during incremental running to exhaustion: relevance for sprint triathlon performance

It is common for the physiological working capacity of a triathlete when cycling and running to be assessed on two separate days. The aim of this study was to establish whether an incremental running test to exhaustion has a negative effect after a 5 h recovery from an incremental cycling test. Eight moderately trained triathletes (age, 26.2 +/- 3.4 years; body mass, 67.3 +/- 9.1 kg; VO2max when cycling, 59 +/- 13 ml x kg x min(-1); mean +/- s) completed an incremental running test 5 h after an incremental cycling test (fatigue) as well as an incremental running test without previous activity (control). Maximum running speed, maximal oxygen uptake (VO2max) and the lactate threshold were determined for each incremental running test and correlated with the average speed during a 5 km run, which was performed immediately after a 20 km cycling time-trial, as in a sprint triathlon. There were no significant differences in maximum running speed, VO2max or the lactate threshold in either incremental running test (control or fatigue). Furthermore, good agreement was found for each physiological variable in both the control and fatigue tests. For the fatigue test, there were significant correlations between the average speed during a 5 km run and both VO2max expressed in absolute terms (r = 0.83) and the lactate threshold (r = 0.88). However, maximum running speed correlated most strongly with the average speed during a 5 km run (r = 0.96). The results of this study indicate that, under controlled conditions, an incremental running test can be performed successfully 5 h after an incremental cycling test to exhaustion. Also, the maximum running speed achieved during an incremental running test is the variable that correlates most strongly with the average running speed during a 5 km run after a 20 km cycling time-trial in well-trained triathletes.

Dystopia on the Health Superhighway

The emerging Information Superhighway is starting to induce visions of dystopia within the medical profession. In several countries, doctors have opposed plans for the establishment of national health data networks. In the most recent example, the Council of the British Medical Association threatened to boycott the government's national data strategy. This action followed the lead of Australian doctors, many of whom have consistently opposed a national wide-area network for health data. In common is the fear that this data linkage will erode medical independence, increase the power of government health authorities, and eliminate the confidentiality of medical information. Doctors have a duty of care to patients to protect confidentiality, and they say the emerging national networks compromise this responsibility. Here, I argue that the emerging health superhighways should either conform to strict privacy standards or they should be demolished.
