Note Associations are presented below the diagonal as Spearman rank order correlations. Corresponding sample sizes are presented above the diagonal. MD-FS, the factor score of motor development before age 2; GM5, gross motor development at age 5; MET7, MET10, MET12, and MET14 represent the exercise behavior at each age (7, 10, 12, and 14 years).
