ABSTRACT:

Purpose: This study aimed to examine the effect of a six-day basketball tournament on the physical demands, perceptual-physiological responses, well-being, and game statistics of elite U-18 players.

Methods: Physical demands (Player Load [PL], steps, impacts, and jumps, all normalized by playing time), perceptual-physiological responses (heart rate [HR] and rating of perceived exertion [RPE]), well-being (Hooper index), and game statistics of 12 basketball players were monitored during six consecutive games. Linear mixed models and Cohen’s d effect sizes were used to assess differences among games.

Results: Significant changes were found for PL·min^-1, steps·min^-1, impacts·min^-1, HR_peak, and Hooper index over the tournament. Pairwise comparisons showed that PL·min^-1 was higher in game #1 than in games #4 (P=0.011, large), #5 (P<0.001, very large), and #6 (P<0.001, very large). PL·min^-1 recorded during game #5 was also lower than PL·min^-1 in game #2 (P=0.041, large) and #3 (P=0.035, large). The number of steps·min^-1 was higher in game #1 than in all other games (all P<0.05, large-to-very large). Impacts·min^-1 were significantly higher in game #3 than in games #1 (P=0.035, large) and #2 (P=0.004, large). The only physiological variable that varied significantly was HR_peak (higher in game #3 than in game #6; P=0.025, large). The Hooper index gradually increased throughout the tournament, indicating poorer player well-being as the tournament advanced. Game statistics did not significantly change among games.

Conclusions: The average intensities of each game and the players’ well-being gradually decreased throughout the tournament. Conversely, physiological responses were mostly unaffected, and game statistics were unaffected.
