如何优化助推器，以帮助女孩获得足够的中度到剧烈的身体活动后，干预是未知的。本研究的目的是：（a）确定在17周的身体活动干预后，与未收到明信片的女孩和对照组相比，收到明信片的女孩是否会在9个月的随访中进行更多的中度至剧烈的身体活动;（B）评估女孩对增强干预的看法。六至七年级的女孩（n = 117）从两个城市，中西部学校相似的人口统计学特征参加了为期17周的体育活动干预，从第三所学校的女孩作为对照组（n = 64）。两个干预学校之一（n = 54）被随机分配到13个动机，个性化定制的明信片，其中包含的信息，以鼓励他们在干预后达到足够的体力活动。另一所干预学校（n = 63）的女孩没有收到明信片，而对照学校的女孩没有收到任何干预。在干预后和9个月随访时，用加速度计测量中度到剧烈的身体活动。女孩在9个月随访时完成明信片评估调查。从干预后到9个月的随访，中度到剧烈的身体活动显著减少，没有组间差异或组与时间的相互作用。根据调查，27名女孩（64.3%）收到了所有明信片。只有15人（35.7%）阅读了他们收到的所有内容。明信片的评价往往是有利的。邮寄助推明信片，以促进女孩的身体活动干预后没有效果。实现这一目标的战略值得研究。
Ways to optimize boosters to assist girls to attain adequate moderate-to-vigorous physical activity following an intervention are unknown. This study’s purpose was to: (a) determine whether girls receiving mailed motivational, individually tailored postcard boosters following a 17-week physical activity intervention would have greater moderate-to-vigorous physical activity at 9-month follow up, as compared to girls not receiving them and those in a control group; and (b) evaluate girls’ perceptions of the booster intervention. Sixth to 7th grade girls (n = 117) from two urban, Midwest schools with similar demographic characteristics participated in a 17-week physical activity intervention, and girls from a third school served as controls (n = 64). One (n = 54) of the two intervention schools was randomly assigned to receive 13 motivational, individually tailored postcards containing messages to encourage them to attain adequate physical activity during the postintervention period. Girls from the other intervention school (n = 63) did not receive postcards, and those in the control school did not receive any intervention. Moderate-to-vigorous physical activity was measured with accelerometers at postintervention and 9-month follow up. Girls completed a postcard evaluation survey at 9-month follow up. Moderate-to-vigorous physical activity decreased significantly from postintervention to 9-month follow up with no between-group differences or group-by-time interaction effect. Based on the survey, 27 (64.3%) girls received all postcards. Only 15 (35.7%) read all that they had received. Evaluations of postcards tended to be favorable. Mailed booster postcards to promote physical activity among girls postintervention were not effective. Strategies to achieve this objective warrant investigation.
