Purpose: The influence of various factors on training-load (TL) responses in basketball has received limited attention. This study aimed to examine the temporal changes and influence of cumulative training dose on TL responses and interrelationships during basketball activity. Methods: Ten state-level Australian male junior basketball players completed 4 × 10-min standardized bouts of simulated basketball activity using a circuit-based protocol. Internal TL was quantifed using the session rating of perceived exertion (sRPE), summated heart-rate zones (SHRZ), Banister training impulse (TRIMP), and Lucia TRIMP models. External TL was assessed via measurement of mean sprint and circuit speeds. Temporal TL comparisons were performed between 10-min bouts, while Pearson correlation analyses were conducted across cumulative training doses (0-10, 0-20, 0-30, and 0-40 min). Results: sRPE TL increased (P < .05) after the frst 10-min bout of basketball activity. sRPE TL was only signifcantly related to Lucia TRIMP (r =.66-.69; P < .05) across 0-10 and 0-20 min. Similarly, mean sprint and circuit speed were signifcantly correlated across 0-20 min (r =.67; P < .05). In contrast, SHRZ and Banister TRIMP were signifcantly related across all training doses (r =.84-.89; P < .05). Conclusions: Limited convergence exists between common TL approaches across basketball training doses lasting beyond 20 min. Thus, the interchangeability of commonly used internal and external TL approaches appears dose-dependent during basketball activity, with various psychophysiological mediators likely underpinning temporal changes. © 2017 Human Kinetics, Inc.
