Position-specific associations between physical demands and match performance in professional basketball

Introduction Understanding how physical demands relate to match performance is essential for optimizing load management and position-specific preparation in professional basketball, as high-intensity competitive calendars require precise control over players' physical efforts. This study examined the relationship between external load and competitive performance, assessing the moderating role of playing position and pre-competition workload (MD-1). Methods Data from 12 professional male players across 18 official matches and 14 training sessions were analyzed, tracking physical demands (Player Load [PL], Dynamic Stress Load [DSL], landings and impacts) and game statistics. Linear mixed-effects models assessed performance outcomes while accounting for playing position, locality, and match outcome. Results Landings·min −1 was positively associated with Points·min −1 ( p = 0.004, β = 0.27, η 2 p = 0.05), indicating that a higher landing frequency is associated with an increased scoring output in our confirmatory models. In exploratory analyses, a significant interaction effect was found between PL·min −1 and PTS·min −1 ( p = 0.046, β = 0.15, η 2 p = 0.02), highlighting that these roles' physical demands are more directly linked to their efficiency and scoring output. However, the vast majority of analyzed physical demands metrics and all of the pre-competition loads showed no significant relationships with performance variables across the conducted analyses. Discussion Overall, the findings indicate that physical loads interact with performance in a way that depends on playing position, particularly highlighting stronger relationships between workloads and scoring outputs; therefore, these findings suggest that position-specific monitoring of selected external-load metrics may provide complementary information when interpreting competitive performance in professional basketball, though these secondary exploratory observations warrant cautious interpretation and future confirmation.
