ResumoTwenty-one male regular long distance runners participated in two 10 km runs one week apart. Their β-endorphin-like immunoreactivity (β-EIR) was assayed in plasma before and immediately after running. Mood was monitored by an adjective check list (Eigenschaftswörterliste, EWL) pre- and post-run. β-EIR was significantly elevated post-run. Self-reliance and good mood scored higher after running. Both mood elevation and plasma β-EIR increase showed a considerable individual variability but there was a significant correlation in the mean values of the two runs between individual β-EIR increases (Δβ-EIR) and the changes of ratings in feeling of pleasantness (ΔFP). High Δβ-EIR corresponded to positive mood change post-run.
