目的：我们研究了舞蹈革命（DDR）的可行性，舞蹈视频游戏，在参与者的家中，以增加体力活动（PA）和减少久坐屏幕时间（SST）。方法和程序：60名儿童（7.5 +/- 0.5岁）被随机分为2：1的比例DDR或等待列表控制（10周延迟）。记录DDR使用情况，通过加速度计客观测量PA。在第0周和第10周自我报告SST。在第28周，两组都获得DDR后，加速度和SST repeated.Results：DDR的平均使用是89 +/- 82（范围0-660分钟）分钟每周（MPW）。DDR组表现出增加的剧烈PA和减少的轻PA;对照组表现出没有增加的中度和/或剧烈PA（MVPA），虽然他们也有减少的轻PA。未观察到组间差异。DDR组还报告SST每周减少-1.2 +/- 3.7 h（hpw）（P < 0.05），而对照组报告增加+3.0 +/- 7.7 hpw（无显著性）。两组间SST差异显著，DDR组SST较低。在第10周至第28周之间，两组均报告SST数值降低。在DDR组中，第28周的SST（8.8 +/- 6.0 hpw）低于基线（10.5 +/- 5.5 hpw; P < 0.03）。需要进一步研究，以更好地描述儿童的特点和复员方案可能促进健康生活方式的背景。
Objective: We examined the feasibility of Dance Dance Revolution (DDR), a dance video game, in participants' homes, to increase physical activity (PA) and to decrease sedentary screen time (SST).Methods and Procedures: Sixty children (7.5 +/- 0.5 years) were randomized in a 2:1 ratio to DDR or to wait-list control (10-week delay). DDR use was logged, PA was measured objectively by accelerometry. SST was self-reported at weeks 0 and 10. At week 28, after both groups had access to DDR, accelerometry and SST were repeated.Results: Mean use of DDR was 89 +/- 82 (range 0-660 min) min per week (mpw). The DDR group showed increased vigorous PA and a reduction in light PA; the control group showed no increase in moderate and/or vigorous PA (MVPA) although they also had a reduction in light PA. Differences between the groups were not observed. The DDR group also reported a decrease in SST of -1.2 +/- 3.7 h per week (hpw) (P < 0.05), whereas the controls reported an increase of +3.0 +/- 7.7 hpw (nonsignificant). The difference in SST between the groups was significant, with less SST in the DDR group. Between weeks 10 and 28, numeric reductions in SST were reported in both groups. In the DDR group, SST at week 28 (8.8 +/- 6.0 hpw) was lower than baseline (10.5 +/- 5.5 hpw; P < 0.03).Discussion: This pilot study suggests that DDR reduces SST and may facilitate slight increases in vigorous PA. Further study is needed to better characterize children and contexts in which DDR may promote a healthy lifestyle.
