Abstract

Purpose: This study examined the physical determinants of 60-m sprint and long jump (LJ) performance and differences between maturity groups in physical characteristics in young male track-and-field athletes. Methods: Competition results, countermovement jump, isometric leg press, 10-5 repeated jump test, and 50-m sprint were collected over 3 seasons for 54 male athletes (age 13 [1] y; stature 160.0 [8.9] cm; body mass, 48.0 [9.8] kg; percentage predicted adult height 92.2% [5.5%]) grouped by maturity status: approaching- (n = 16), circa- (n = 19), and post-peak height velocity (PHV) (n = 19). Results: There were significant between-group differences in 60 m, LJ, and all physical testing variables (P < .001, g = 0.88–5.44) when comparing the approaching- and circa-PHV groups with the post-PHV group. Significant differences were identified between the approaching- and circa-PHV groups in 40-m (P = .033, g = 0.89), 50-m (P = .024, g = 1.64), and 60-m (P < .001, g = 0.89) sprint times. Countermovement jump and 50-m sprint variables were consistently important for projection of 60 m and LJ performance across the valid multivariate models. Conclusions: Large differences in performance across maturity groups highlight the importance of understanding athletes’ maturity status to accurately interpret performance. Several physical performance variables were important for projecting competition 60 m and LJ performance.
