Mining the training load metrics in basketball: a systematic review

This systematic review aimed to analyze the internal and external training load metrics used in basketball training and competition. A systematic search following PRISMA guidelines was conducted in the PubMed database from the earliest record to May 2022, and methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. A systematic search of the PubMed database identified 95 records, from which seven studies met the inclusion criteria. Internal load was primarily quantified using peak heart rate (HR) during 3×3 matches (%HRmax, n = 1), HR monitoring ( n = 3), training momentum ( n = 1), and rating of perceived exertion (RPE, n = 4). External load metrics included changes of direction and peripheral fatigue ( n = 1), vertical jumps ( n = 2), motion analysis, and GPS tracking ( n = 1). The most commonly applied training load measures were RPE, HR-based monitoring, and time-motion analysis. These findings provide valuable insights for optimizing workload management in basketball. Coaches can use individualized training approaches considering positional demands, integrate small-sided games to manipulate load, and apply wearable technology for real-time monitoring. Additionally, injury prevention strategies should incorporate acute-to-chronic workload ratios. However, it must be acknowledged that the restricted use of PubMed as the sole database severely limited the comprehensiveness of the review, and therefore the conclusion that only seven studies exist should be interpreted with caution. Further research is needed on female and youth players to enhance evidence-based monitoring strategies across different populations.
