Personality Traits and Vitamin D3 Supplementation Affect Mood State 12 h Before 100 km Ultramarathon Run Participation in extreme endurance sports enjoys increasing popularity, making more people involved. Participation in a 100 km run is associated with a large physiological and mental stress that can influence the reflux. The aim of this study was therefore to find out whether personality, experience and motives for participation associated with the mood and the runner’s changes and whether the supplementation with vitamin D3 influences the mood 12 hours before and 12 hours after the barrel. The subject group consisted of 20 experienced marathon and ultramarathon runners participating in a 100 km run. All participants were men between 31 and 50 (M = 40.75, SD = 7.15). The group was divided into two equal subgroups: the placebo group and the group with vitamin D3 supplements. The personality traits were assessed with the Polish version of Eysicks EPQ-R 106, and the mood states were measured twice (12 hours before and after the barrel), using the Polish version of Mathews, Chamberlain and Jones’s umacl. Motives for participating in ultramarathons were measured with the IPAO of Lipowski and Zaleski. The vitamin D3 mirrors correlated very strongly with the energetic excitement (EA) and strong hedonian tone (HT) for 12 hours before the barrel. There were no significant correlations between vitamin D3 mirrors and reflections after the barrel. In addition, extraversion correlated with tempus excitation (TA) and EA, while neurotizism moderately with Ta and Ht.
Both the personality and vitamin D3 supplementation are referred to the mood of the runners before the barrel. The whole work can be found under https://www.frontiersin.org/articles/10.3389/fpsyg.2018.00980/full
