PURPOSE: To characterize total player load (TPL) for 1 collegiate basketball (NCAA Division1) team’s entire season.

METHODS: We compiled routinely collected wearable sensor data in 11 male varsity basketball players (20.5 ± 1.7y; 200.7 ± 11.1 cm; 97.1 ± 10.7 kg) for 1 season. Independent variables were Player Position: Centers, Forwards, Guards; Player Status: Rotation (>15 min average playing time per game), Non-Rotation; Event Type: games, practices; and Season Phase: pre-season (PS = start of academic year to start of official team practices), in-season1 (IS1 = official team practices prior to the start of game events), in-season2 (IS2 = earlier season, primarily non-conference games and practices), in-season3 (IS3 = later season, primarily conference and post-season games and practices). The dependent variable was TPL, reported as an Arbitrary Unit (AU), and calculated from tri-axial accelerations during all movements from the start to finish of each event. Separate 1x3 ANOVAs were used to compare TPL among the 3 position types for practices and games at each season segment. Post hoc contrasts were used where appropriate. T-tests were used to compare TPL between player status’. Alpha level was 0.05.

RESULTS: We observed no differences in TPL among position groups during PS (p = .71, Table 1). However, Centers had significantly lower TPL compared to other position groups in IS1 & IS3 practices and during games (p < .05). No differences were observed among the positions during IS2. Centers exhibited lower TPL during game events than the other positions (p < .001). There were no differences between TPL in rotation and non-rotation players across all season phases in practice exposures, however rotation players had significantly higher TPL during game events than non-rotation players (p < .05).

CONCLUSION: Rotation players TPL was higher during games only. Centers exhibited the lowest TPL during IS1&3 practices and games suggesting workload demands are less.
