En meta-analyse af 64 studier om kønsforskelle i motorisk præstation blandt børn og unge fandt 702 effektstørrelser baseret på data fra over 31.000 deltagere. Resultaterne viste signifikante kønsforskelle for 12 af 20 opgaver, men nogle opgaver viste små forskelle uafhængigt af alder. Udviklingen af kønsforskelle diskuteredes i forhold til biologiske og miljømæssige faktorer.

Hele abstrakt på originalsprog:
Conducted a meta-analysis of 64 studies that reported gender differences on motor performance during childhood and adolescence. Findings yielded 702 effect sizes based on data from 15,518 female and 15,926 male 3–20 yr olds. Age was regressed on effect size, and the relation was significant for 12 of 20 tasks (e.g., balance, catching, grip strength, shuttle run, throw velocity, tapping). Several types of age-related curves were found; the curve for a throwing task was the most distinctive. Five of the tasks followed a typical curve of gender differences across age. For 8 tasks, gender differences were not related to age, and effect sizes were small. Results are discussed in relation to the development of gender differences to biological and environmental sources. A bibliography of the 64 studies is appended.
