Abstract: Without a doubt, in todays competitive world, the condition of survival in any organization is improving labor productivity. Labor (human resource) plays a key role in this area and is of great importance as a valuable source for organizations. The purpose of the present study is to study labor productivity and present the conceptual model of effective factors. The statistical population of this study included all staffs in Irans sport federations (n = 1394). According to Morgans table, 302 subjects were selected as samples by stratified random sampling method. The content validity and construct validity of the research instrument were respectively confirmed by Expert Panel method and exploratory confirmatory factor analysis. Cronbachs alpha test was used to measure the reliability. The (α = 0/98) labor productivity was obtained by using the productivity scores of each federation and putting them in the formula of labor productivity. The (PL ) = (PT ÷ Tw )×Pw . Then, the factors affecting productivity were identified by a questionnaire and the effectiveness rate of each one on sport federations labor productivity was studied according to structural equations by Amos Software. The results of statistical analyses showed that the rate of labor productivity in federations is at an optimal and favorable level. Using this instrument and the results of the proposed conceptual model can improve the effectiveness and efficiency of staffs employees.
