Träning och ekonomiskt beteende
? Effekterna av konditionsträning på överkonfidens, riskbenägenhet och välbefinnande
It is well proven that physical exercise has an impact on our bodies as well as our minds. The aim of this study is to examine if this impact also affects economic behaviour. Three hypotheses regarding the impact of acute exercise on overconfidence, risk enhancement and well-being have been tested by collecting questionnaires from 364 participants at Friskis & Svettis, Kungsholmen who all were asked to answer the questions either before or after exercising. The differences between the before and after group were analysed, indicating small increases in all three test areas after exercising. These increases were, however, not large enough to reject any of the null-hypotheses of zero effect on the given five per cent significance level. When increasing the level of significance to the ten per cent level, a significant effect was found among male participants in the field of risk enhancement and in one of the questions measuring overconfidence. Finally, methodological issues are discussed and suggestions for future studies, where these issues have been corrected, are proposed.
