This study analyzed records of female athletes among the average records of a total of 2,208 male and female elementary, middle and high school track-and-field and swimming athletes who advanced to the finals of their respective sports at the China National Youth Games in 2008, 2012, and 2016 by using the paired-t test. Based on the comparative analysis of the sports and school levels, the following conclusions were drawn from the study:
1) Records of elementary school athletes showed statistical differences in gender for swimming and track-and-field (p<.001).
2) Records of middle school athletes showed statistical differences in gender for swimming and track-and-field(p<..001).
3) Records of high school athletes showed statistical differences in gender for swimming and track-and-field(p<.001).
4) Records of elementary school athletes showed no statistical differences in gender for track and field.
5) Records of middle school athletes showed statistical differences in gender for track and field(p<.001).
6) Records of high school athletes showed statistical differences in gender for track and field(p<..001).
7) Records of elementary school athletes showed no statistical differences in gender for high jump and long jump.
8) Records of middle school athletes showed no statistical differences in gender for high jump and long jump.
9) Records of high school athletes showed no statistical differences in gender for high jump and long jump.
10) There were statistical differences among school levels for swimming (p<.001).
11) There were statistical differences among school levels for track-and-field (p<.001).
The above conclusions are meaningful as they demonstrate record differences in gender among sports and among school levels. If subsequent studies can further shed light on scientific grounds explaining such differences, they would allow for better understanding of growth and development of children and youth.
