Effects of Weekly Basketball Training Distribution on Executive Function in Adolescents (VMBT-EF)

31. juli 2026 opdateret af: Xiaodong Cheng, Xi'an Medical University

Effects of Volume-Matched Weekday-Distributed Versus Weekend-Concentrated Basketball Training on Executive Function in Adolescents: A Three-Arm Randomized Controlled Trial

his study examined whether different ways of distributing the same weekly amount of basketball training affect executive function in adolescents. A total of 120 adolescents were randomly assigned to one of three groups: weekday-distributed basketball training, weekend-concentrated basketball training, or a control group that continued its usual activities.

Participants in both basketball training groups completed 180 minutes of training per week for 8 weeks. The weekday-distributed group trained for 36 minutes per session, five days per week, whereas the weekend-concentrated group trained for 90 minutes per session, two days per week. Executive function was assessed before and after the intervention.

The study aimed to determine whether basketball training improves executive function compared with usual activities and whether distributing the same weekly training volume across weekdays produces different effects from concentrating the training on weekends.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Weekday-Distributed Basketball Training
Participants completed 180 minutes of basketball training per week for 8 weeks. The training was distributed across five weekday sessions, with each session lasting 36 minutes.
Participants completed basketball training five days per week for 8 weeks. Each session lasted 36 minutes, resulting in a total weekly training volume of 180 minutes.
Eksperimentel: Weekend-Concentrated Basketball Training
Participants completed 180 minutes of basketball training per week for 8 weeks. The training was concentrated into two weekend sessions, with each session lasting 90 minutes.
Participants completed basketball training two days per week for 8 weeks. Each session lasted 90 minutes, resulting in a total weekly training volume of 180 minutes.
Ingen indgriben: Usual Activity Control
Participants maintained their usual daily activities and received no additional structured basketball training during the 8-week study period.

Foranstaltningsbeskrivelse
Tidsramme
Change From Baseline in Flanker Reaction-Time Interference Effect
Tidsramme: Baseline and immediately after the 8-week intervention
Inhibitory control was assessed using a computerized Flanker task at baseline and immediately after the intervention. The reaction-time interference effect was calculated as the mean reaction time for incongruent trials minus the mean reaction time for congruent trials and was expressed in milliseconds. Change from baseline was calculated as the post-intervention value minus the baseline value. Lower interference scores indicate better inhibitory control, and a negative change indicates improvement.
Baseline and immediately after the 8-week intervention
Change From Baseline in 1-Back Task Accuracy
Tidsramme: Baseline and immediately after the 8-week intervention
Working memory was assessed using a computerized 1-back task at baseline and immediately after the intervention. Performance was measured as the percentage of correct responses, ranging from 0% to 100%. Change from baseline was calculated as the post-intervention accuracy minus the baseline accuracy. Higher accuracy scores indicate better working memory performance, and a positive change indicates improvement.
Baseline and immediately after the 8-week intervention
Change From Baseline in More-Odd Shifting Task Switching Cost
Tidsramme: Baseline and immediately after the 8-week intervention
Cognitive flexibility was assessed using a computerized More-Odd Shifting task at baseline and immediately after the intervention. Switching cost was calculated as the mean reaction time for switch trials minus the mean reaction time for repeat trials and was expressed in milliseconds. Change from baseline was calculated as the post-intervention value minus the baseline value. Lower switching-cost values indicate better cognitive flexibility, and a negative change indicates improvement.
