The purpose of this study was to measure the precompetitive anxiety and affective states of climbers, particularly with regard to sex and types of competition. 37 men (M = 25.9, SD = 3.8 yr.) and 10 women (M = 25.9, SD = 4.2 yr.), climbers who enrolled in Indoor Sport Climbing Competition, voluntarily participated in two different types of competition-speed and difficulty indoor climbing. The Competitive State Anxiety Inventory-2 and the Positive and Negative Affect Schedule were administered to all climbers just before the competition. The Sport Competition Anxiety Test was also administered to control competitive trait anxiety. Multivariate analysis of covariance yielded a significant interaction of sex and type of competition for affective state (Hotelling T-2 = 0.21; F-2,F-33 = 3.43, p < .05). Follow-up univariate analysis indicated that the mean Negative Affect score of women climbers before the difficulty competition was higher than mean Negative Affect scores of men before both speed and difficulty competitions and also the mean for women climbers before the speed competition (F-1,F-34 = 6.15, p < .05). The results partially supported the hypothesis of differences in negative affect by sex and types of competition.
