Introduction. This sports-science-related article heavily relies on studies that have reported an increase in beta-endorphin (â-EP) concentration in plasma in response to physical activity. It examines the psychological and physiological effects of physical activity and exercise and reports on a research-experiment-based, endorphin-hypotheses-related pilot study aimed at exploring mood-related â-EP effects occurring in physically active male and female individuals aged 45-55 in response to physical load. Material and methods. Six 45 to 55-year-old individuals (3 males and 3 females) rated as exhibiting moderate and high levels of physical activity in sport's laboratory. International Physical Activity Questionnaire (IPAQ) was used to establish physical activity level. For facial expression analysis a short interview was applied, using software “FaceReader 3.0” (FR). As a load test a veloergometer exercise test was used, and Beta-endorphin (â-EP) levels were measured from venous blood. Results. The findings demonstrated an increase in â-EP levels in 50% of the subjects. No positive relation between â-EP increase and happiness has been observed. In four subjects an increase in disgust was observed due to the laboratory conditions. Five minutes after the load test FR data recorded the reduction or disappearance of negative emotions for all research subjects. Conclusions. Further investigation into the relationship of plasma levels of â-EP and the emotional state of the individual involved in physical activities is needed. This necessitates a further insight into how exercise-elevated endorphins (â-EP) affect mood state outside laboratory conditions. Therefore, a further investigation of people involved in physical recreation activities outdoors is envisaged.

Introduction. The aim of this study was to assess selected psychological, physiological and technical factors related to ski hiking in order to offer some recommendations for ski hikers and ski hike organisers. Material and methods. The hike lasted 8 hours and the hikers covered a distance of 24 kilometres. The ski hikers' emotional state was assessed three times: before the ski hike, 1 hour after the hike and 16 hours after the hike. Their skiing technique was evaluated during the first part of the hike and at the end of the hike. The heart rate of the skiers was recorded over the course of the hike. The data were then processed and analysed statistically. Results. When comparing the data collected for the selected factors during the ski hike, some significant correlations were found. A significant correlation was observed between the level of fear experienced before the ski hike and cycle length for the diagonal stride (r=−0.791, p<0.05), which meant that the hikers with poorer ski technique felt more afraid before the hike. However, these hikers also showed lower levels of sadness 16 hours after the hike (r=0.804, p<0.05). A significant negative correlation (r=−0.849, p<0.05) was found when comparing the average heart rate frequency and the level of anger experienced after the hike, that is the hikers who had a lower heart rate were angrier after the hike. The results helped to develop some important recommendations for ski hikers and ski hike organisers.
