Factors such as training intensity, volume, frequency, and density must be carefully managed to promote positive adaptations in athletes (2). The concept of training load is not merely a measure of the amount of work performed, it is a complex interplay of factors that can significantly influence an athlete’s performance trajectory (3). Understanding how to optimize training load is essential to maximizing athletic performance while minimizing the risks of excessive fatigue, injury, and overtraining, which can negatively impact an athlete’s performance and ability to compete and train effectively, as well as overall health (1).engTraining loadAthletic performanceInjury preventionStrength and powerDevelopmentRecovery strategieseditorial10.3389/fspor.2025.1574500
