Bg. Berger et al., RELATIONSHIP BETWEEN EXPECTANCY OF PSYCHOLOGICAL BENEFITS AND MOOD ALTERATION IN JOGGERS, International journal of sport psychology, 29(1), 1998, pp. 1-16
Two experiments investigated the possible relationship between expecta
ncy of psychological benefits from exercise and acute mood change. In
the first study, participants (N = 71) reported their expectancies ris
ing an open-ended instillment and completed the POMS before and after
jogging. Results of a 2 (pre; post-exercise) x 2 (gender) x 3 (class)
MANOVA indicated that there were significant acute mood benefits for w
omen (p < .0001) and for men (p < .03). Multiple regression analysis i
ndicated that the relationship between expectancy of psychological ben
efits and mood change approached significance (p < .06). In the second
study, participants (N = 68) responded to an objective expectancy que
stionnaire and again completed the POMS before and after jogging. Resu
lts of the 2 x 2 x 3 MANOVA indicated a significant pre-to post-exerci
se mood change (p < .0001). No relationship was found between expectan
cy and mood change. In conclusion, joggers in both studies reported si
gnificant short-term mood benefits, but there was no conclusive eviden
ce that expectancy was related to mood alteration.
