The purpose of this study was to investigate the role of passion in predicting job and life satisfaction in fitness leaders and examine the sex and job experience differences in these variables. Two hundred (Mage=29.52+-4.38) fitness leaders participated in this study. “Passion Scale” (Vallerand et al., 2003), “Satisfaction with Life Scale” (Diener et al., 1985), and “Minnesota Job Satisfaction Questionnaire” (Weiss et al., 1967) were administered to participants. Stepwise Multiple Regression Analysis was used to determine whether fitness leaders’ levels of passion predict their job and life satisfaction. 2x2 (sex x year of job experience) Multivariate Analysis of Variance (MANOVA) was used to test the sex and year of job experience differences in passion and job satisfaction. Furthermore, 2x2 ANOVA was conducted to test sex and year of job experiences differences in life satisfaction. Results of Regression Analysis indicated that obsessive passion was a significant predictor of extrinsic job satisfaction; both harmonious and obsessive passion were a significant predictor of intrinsic job satisfaction, general job satisfaction and life satisfaction of fitness leaders (p<.01). The MANOVA results showed that participants’ passion scores differed with regard to year of job experiences (p<.05), but there were table Oxygen Analyzer (Cosmed K4b2, Italy) for each minute, and [La] was measured for every 3 minutes by taking arterialized blood from earlobe (YSI 1500, USA). RV, VO2 and HR corresponding to the fixed [La] were predicted from RV-[La], RV-HR and RV-VO2 , which were measured from VO2max and LT tests, by using polynomial curves and equations. As a result of multivariate of variance analysis, although VO2max and RV of midfielders corresponding to fixed [LA] were higher than the others, no significant differences were found on RV, percentage of VO2max and HR at the fixed [La] among the playing positions. As a result of the study, examined aerobic endurance characteristics of young soccer players showed similar physiological responses among the playing positions.
