Junior Athletes' Goal Orientation, Motivation, and Emotional and Physical Exhaustion
Frode Moen,Roger A. Federici,Einar M. Skaalvik 한국코칭능력개발원 2014 International Journal of Coaching Science Vol.8 No.2
Despite the considerable concern regarding burnout in sports, there has been a paucity of research investigating burnout’s relation to goal orientation and motivation. The purpose of the present study was therefore to explore a theoretical model of correlations between goal orientation, motivation, and emotional and physical exhaustion (a dimension of burnout) among junior athletes in elite sports gymnasiums in Norway. The theoretical model proposed that mastery goal orientation was positively and directly related to intrinsic motivation and negatively related to extrinsic motivation and exhaustion. Performance goal orientation was expected to be inversely related. Additionally, extrinsic motivation was expected to be positively related to exhaustion, whereas intrinsic motivation was expected to be negatively related. The results in this study partially confirm the proposed theoretical model. Mastery orientation was positively related to intrinsic motivation and negatively related to extrinsic motivation. However, mastery orientation was only indirectly related to exhaustion, mediated by intrinsic and extrinsic motivation. The analyses revealed identical but inverse patterns for performance orientation.

This article investigates the impact of mindfulness on stress, perceived performance in school and sports, and on athlete burnout. In the present investigation 483 Norwegian junior athletes from seven different schools for elite sports were invited to partake in an online survey of which 382 athletes responded (79%). The athletes were from different sports such as cross country skiing, Nordic combined, ski jumping, volleyball, handball, track and field, ice hockey, biathlon, cycling and orienteering. We tested whether mindfulness affected stress, perceived performance in school and sports, and athlete burnout utilizing structural equation modeling. As hypothesized, mindfulness was negatively related with stress and burnout, whereas stress was positively related with burnout and negatively related with perceived performances in school and sports. Mindfulness was positive related with perceived performances in sports and in school, whereas perceived performances in sports where negatively related with burnout. Hence, for this investigation it seemed that mindfulness was an important stress buffer and may help elite youth athletes to avoid burnout and perform better. The results are discussed in regard of applied implications and possible future research.

Junior athletes often work hard to become elite athletes. In their career they will meet a range of potential loads that they must overcome in order to reach their fully potential. Sometimes the total load becomes too much to cope with and burnout could be one consequence. In the present investigation 483 junior athletes from seven different schools for elite sports were invited to partake in an online survey of which 382 athletes responded (79%). We tested whether need satisfaction was a predictor for burnout utilizing structural equation modeling, and as hypothesized, basic needs were negatively related with burnout. Hence, for this investigation it seemed that environments that satisfy the need for autonomy, competence and relatedness might help elite youth athletes to avoid burnout. The results are discussed in regard of applied implications and possible future research.

Neutron-Induced Activation Cross Sections on Hafnium Isotopes from the Threshold to 20 MeV
V. Semkova,N. Janeva,N. Koyumdjieva,R. Jaime Tornin,A. Moens,A. J. M. Plompen,K. Volev 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
Results of new cross section measurements are presented for the following neutron-induced reactions: ^(178)Hf(n,α)^(175)Yb, ^(180)Hf(n,α)^(177)Yb, ^(177)Hf(n,p)^(177)Lu^g, ^(178)Hf(n,x)^(177)Lu^g, ^(180)Hf(n,p)^(180)Lu, ^(180)Hf(n,n'α)^(180)Hf^m, ^(174)Hf(n,2n) ^(173)Hf, ^(176)Hf(n,2n)^(175)Hf, and ^(177)Hf(n,3n)^(175)Hf obtained with the activation technique. The irradiations were carried out at the 7-MV Van de Graaff accelerator at IRMM, Geel. Quasi monoenergetic neutrons with energies between 14.8 and 20.5 MeV were produced via the ^3H(d,n)^4He reaction at E_d = 1, 1.4, 2, 3, and 4 MeV. The ^3H(p,n)^3He reaction was employed for the production of neutrons in the 2 - 3 MeV energy range. Both natural and enriched samples were used to facilitate correction for interference between reactions leading to the same product. The radioactivity of the samples was determined by standard γ-ray spectrometry using HPGe detector. The current measurements are compared with the data from other authors and Evaluated Nuclear Data Files. Cross sections for three of the studied reactions are reported for the first time.
