Body Composition, Cardiovascular Fitness, and Muscular Fitness Were Not Related in Minority Female College Freshmen: 3067 Board #8 May 29, 3

RESULTS: Girls ranged in age from 11 to 14 years (M=12.0, SD =0.66). Most were Black (n=82, 70.1%) and in the free or reduced-price lunch program (n=111, 90.1%). There was only a significant main effect of time (F1, 59=51.42, p<.001, partial η2=.47) on MVPA. MVPA did not change significantly from T0 to T1, but decreased significantly from T1 to T2. No betweengroup differences occurred. According to the survey, 64.3% (n=27) of girls reported receiving 13 postcards, and 40.7% of those girls (n=11) read all 13. About half of the girls (n = 21) reported that receiving the postcards helped them to stay active, and less than half (n = 18) talked with others about the ideas listed on the postcards for increasing PA. CONCLUSIONS: The findings demonstrate no effect of using mailed postcards as boosters to help girls sustain MVPA. One possible explanation is that girls did not read or apply the ideas on the postcards even though they received them. Innovative and effective strategies to help maintain PA post-intervention warrant further investigation. Supported by NIH grant (R01HL109101-02S1; LBR, PI)
