Although the standing long jump (SLJ) is a popular physical fitness assessment,
it lacks an updated criterion-reference standard. This study generated the
first normative SLJ test data for Chinese aged 8 - 18. Methods: From September 2005
to December 2011, comprehensive physical fitness assessments were conducted
on 12,712 school students. The SLJ performances were significantly different between boys and girls (all age groups, p < 0.01). Results: The boys performed
better than the girls in each age group. The mean difference increased as the
age increased, depicting a prominent variance in muscular strength between
boys and girls at age 12, and the variances became larger at age 18. Girls in
the 70th percenttile performed similarly to boys performing in the 10th percentile.
The onset of muscle strength for boys found in this study corresponded to the
onset age of testosterone maturation of Chinese boys investigated in previous
studies. Linear regression found age and BMI predicting SLJ significantly for
boys and girls, explaining better SLJ results in older boy and the effect of
their heavy body size. Conclusions: This study indicated a muscular strength
difference between genders during growth and added supporting evidence to
the hormonal influence of muscle growth during puberty.
