Summary: This study aimed to analyze whether auto-regulating horizontal jump (HJ) performance using minimal individual difference (MID) could be used to regulate training load in young soccer players. Nineteen Brazilian young players were divided into a regulated group (RG) and a control group (CG). After a familiarization period, the HJ reliability was quantified to determine the MID. he study determined the MID after a familiarization period to regulate the RG's neuromuscular training over six weeks, contrasting with the CG's pre-planned training. Performance metrics included countermovement jump (CMJ), HJ, sprint test (10–30 m), and maximal running speed in the 30–15 Intermittent Fitness Test (V-IFT). These were assessed at the beginning of training (T0), in the middle of training (T1) and post-intervention (T2). The internal load was measured using rating of perceived exertion (sRPE) and variables like acute-sRPE, monotony-sRPE, and strain-sRPE. At the outset, both groups had comparable performance levels. The RG showed a significant improvement in HJ at T2 (T2 > T0; p = 0.042, ES = moderate), while both groups improved in V-IFT at T1 (p < 0.001, ES = moderate-large) and T2 (p < 0.001, ES = moderate). The RG presented more total jumps during training than the CG (p = 0.007, ES = large). In conclusion, auto-regulating training based on HJ performance led to better improvements in HJ distance for the RG compared to traditional training. The findings suggest that coaches and researchers should consider HJ performance-based auto-regulation to adapt and individualize training loads and enhance young soccer players' physical capabilities.
