Intra and inter variation in training load, recovery state and technical–tactical performance across a standard microcycle in Sub-elite youth football players

These findings demonstrate that the microcycle followed a structured pattern, with matches concentrating objective intensity and training sessions eliciting greater perceived effort. Practically, training for U11 should emphasize motor efficiency and load regulation, while U13 programs should target high-intensity capacity and tactical coordination. Over time, integrating multidimensional monitoring (GPS, sRPE, TQR, FUT-SAT) may guide coaches in aligning training stimuli with long-term development goals, bridging physical, perceptual, and tactical competencies in sub-elite youth football.
