The purpose of this study was to: 1) provide comparative isometric mid-thigh pull (IMTP) force-time characteristics for elite youth soccer players and 2) determine the effect of age and maturation on IMTP force-time characteristics. Elite male youth soccer players (U12 n = 51; U13 n = 54; U14 n = 56; U15 n = 45; U16 n = 39; U18 n = 48) across 3 maturity offset groups (Pre n = 117; circa n = 84; Post-PHV n = 92) performed two maximal IMTP trials on a portable force platform (1,000 Hz). Absolute and relative values for peak force (PF) and impulse over 100 ms and 300 ms, were analyzed. A full Bayesian regression model was used to provide probable differences similar to that of a frequentist p value. Advanced age and maturation resulted in superior IMTP force-time characteristics. Peak force demonstrated high probabilities of a difference between all consecutive age groups (p>0.95). For absolute and relative impulse (100, 300 ms) only two consecutive age groups (U14-15’s; U16-18’s) demonstrated high probabilities of a difference (p>0.95) with large effects (d =0.59 to 0.93). There were high probable differences between all maturity offset groups for PF and impulse with medium to large effects (d = 0.56 to 3.80). These were also reduced when expressed relative to body mass (relative PF, relative impulse). This study provides comparative IMTP force-time characteristics of elite male youth soccer players. Practitioners should consider individual maturation status when comparing players given the impact this has on force expression.
