    The influence of initial selection age, relative age effect and country long-term performance on the re-selection process in European basketball youth national teams2021Ingår i: Journal of Sports Sciences, ISSN 0264-0414, E-ISSN 1466-447X, Vol. 39, nr 4, s. 388-394Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aims of the study were to: (a) analyse the re-selection patterns in European youth basketball national teams, and (b) investigate how the chance of re-selection is influenced by the initial selection age and relative age of the players, as well as the long-term performance of the country at the youth level. The sample consisted of 8362 basketball players (5038 men, 3324 women) born 1988–1997 who have participated in at least one U16, U18 or U20 European youth basketball championship between 2004 and 2017. The results from the survival analysis showed that around 75% of male and 80% of female players participating in a championship were re-selected the following year. Also, initial selection age, relative age effect, and the country long-term performance influenced the re-selection rates, with relationships being different between men and women. To conclude, the results of the present study show that the re-selection process by which players progress in European youth national basketball teams is complex and influenced by several different factors. © 2020 The Author(s).

    The temporal relations across burnout dimensions in athletes2018Ingår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 28, nr 3, s. 1215-1226Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Burnout is a construct that has garnered considerable attention in sport psychology within recent years. Several hypothesized models regarding how the three dimen-sions (exhaustion, devaluation, and reduced sense of accomplishment) temporally relate to each other have been advanced. One proposal outlined by Maslach and Leiter suggests that exhaustion predicts devaluation which predicts reduced sense of accomplishment. However, there is no consensus among researchers as it has been argued that exhaustion predicts devaluation and reduced accomplishment separately. The aim of this study was to test multiple alternative hypotheses regarding the rela-tionships of the burnout dimensions in athletes. Two samples of Swedish youth elite athletes with differing time spans between measurements were used. Specifically, one sample involved time- intensive measures collected every week over an eight- week period, and the other sample included four measurement points across an 18- month period. Results showed that none of the previously proposed models outlining the temporal relations of burnout dimensions were supported. Statistical analysis of the models including the cross- lagged predictions of dimensions did not have any statistically significant impact except when exhaustion negatively predicted devalu-ation between time 1 (month 0) and time 2 (month 6) in the 18- month sample; this relation faded in the following time points. Further, issues regarding the stability of devaluation and reduced sense of accomplishment emerged as their autocorrelation were very weak in the time- intensive sample. These findings raise a number of points for further theoretical and practical discussions about the athlete burnout construct. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
