RESULTS: Males ran faster than females at every age in the 100, 200, 400 and 800 m (P<0.001). When combining all running events, the sex difference (%) was 4.0 ± 1.7% between 7-12 years and increased to 6.3 ± 1.1% at 13 years, and 12.6 ± 1.8% at 18 years (P<0.001). Similarly, males jumped higher and further than females at every age (P<0.001). For long jump, the sex difference was 6.8 ± 2.8% between 7-12 years, increasing to 8.5 ± 1.7% at 13 years, and 22.7 ± 1.4% at 18 years (P<0.001). For high jump, the sex difference was 5.3 ± 5.2% between 7-12 years, increasing to 10.3 ± 2.4% at 14 years, and 18.4 ± 2.04% at 18 years (P<0.001).
CONCLUSION:Prior to puberty in elite youth track and field athletes, there is a small but consistent sex difference, such that males run faster and jump higher and further than females. The sex difference in performance was event dependent and increased significantly from ~12 years for running and 13-14 years in jumping events.
But, hey, it is preprint ...
Of course, if many papers found results that support the very same conclusions of acceptable papers, that also reflect the established knowledge for decades, and the established and published records of children from different countries and international records too, does that mean that maybe, just maybe, the findings are conclusive?
