​A recent study titled "Exploring Dynamics of Perceived Exertion Rating in Successive Football Training Sessions: Insights into Training Load Sensitivity to Exercise Duration and Physiological Variables in Youth Players" delves into how perceived exertion (RPE) evolves across consecutive football training sessions, particularly among youth athletes. The research highlights that RPE is not solely influenced by external load but is also significantly affected by factors such as session duration, physiological markers, and individual player responses.

Key findings from the study indicate that longer or more intense sessions can lead to elevated RPE scores, even when external workloads remain consistent. This underscores the importance of monitoring both internal and external load metrics to prevent overtraining and ensure optimal performance. The study also emphasizes the variability in individual responses, suggesting that personalized training adjustments are crucial for effective load management.​
