Both functionalist and conflict theories of sports suggest that partic
ipation in sports may have a positive influence on achievement in scie
nce, especially for young women. The research presented here found Mat
young women's involvement in high school sports often has a strong an
d positive association with their success in science in their sophomor
e and senior years of high school, but that participation in cheerlead
ing is usually negatively associated with success in science. It also
found that involvement in sports is a factor in young African American
women's success in science, but riot always a positive factor. Compar
able analyses for young men showed that sports activities are much les
s important in predicting their science experiences and that when thes
e activities are significant, they have a negative influence.
