The aim of this study was examine the variation of individual performance profiles in basketball, between national and international leagues and examine if the magnitude of this variation is affected by age and playing position. The players’ profiles, including age and playing position were collected from official league websites. A total of 1627 official boxscores from national and international leagues, from 2014-2015 and 2015-2016 seasons, were considered for this study. Besides the traditional notational analysis, we also computed the distance traveled and days of rest between national and international matches. Firstly, was realized a two-step cluster analysis to group the players into different groups. Posteriorly, one-way independent measure ANOVA was used to explore the difference of the within and between the obtained clusters; and finally, a descriptive discriminant analysis was conducted to identify which variables best discriminate the obtained clusters. The results showed that the number of clusters is different between both competitions, revealing a variation in the individual performance profiles. Factors such as distance traveled, time played and players' age, affected the performances in the international competition, however in the national competitions, distance traveled, match break and time played were the variables with a great discriminatory influence. This information can help in the development and optimization of performance specific profiles according with competitions, and can facilitate the detailed planning for specific groups of players and teams, contemplating the performance on the training session and on the game.
