Effects of different interval durations on training load and post-exercise recovery in 3×3 basketball

Abstract

Aim of the study: The aims of this study were (I) to measure external and internal training loads during 1-, 2-, 3-, and 4-min simulated 3x3 basketball games, with 1-min recovery periods following each game and (II) to evaluate the recovery rates of heart rate and the muscle oxygen saturation following 1- , 2-, 3-, and 4-min play. Methods: Twelve (n = 12) elite male 3×3 basketball players (age: 26.6 ± 5.6 years; height: 196.8 ± 5.5 cm; body mass: 92.0 ± 9.5 kg; training experience: 15.4 ± 3.9 years; and 3×3 basketball training experience: 4.8 ± 1.6 years) representing Lithuania national team were recruited and asked to perform two controlled simulated matches. External load volume was quantified by total distance (m), number of sprints and jump count. As for external load intensity, distance rate (m/min), average speed (km/h), maximal speed (km/h), jump rate (jumps/min), average height jump zone total (cm), heart rate (bpm) and muscle oxygen saturation (%) were evaluated. Results: A repeated-measures factorial analysis of variance was used to compare differences in performance between intervals. Overall, the results showed that using different play-time scenarios substantially impacted training load and physiological recovery, with significant differences in the majority of parameters. Conclusions: These findings provide insight into potential interventional implications and advancement of training protocols for 3×3 basketball, highlighting the importance of post-exercise recovery protocols that are tailored to the specific playing duration.
