The purposes of this study were (1) to determine if three selected aerobic dance related conditions would result in chronic alterations of flexibility of college women and (2) to compare flexibility measures of college age females during a semester of aerobic dance instruction. Subjects were sixty-three college women enrolled in aerobic dance, bowling, and archery classes. Eight flexibility measures were obtained during the third and eleventh weeks of the experimental period. Data were analyzed by a factor analysis the Pearson Product Moment Correlation, and eight oneway analyses of covariance. Conclusions of the investigation were (1) a program of aerobic dance alone is not sufficient to promote flexibility, and (2) supplemental flexibility activities of ten minutes duration used with aerobic dance training are beneficial in increasing hip flexion.
