This study aimed to examine the effect of a 9-week SPARK program on physical activity (PA), cardiorespiratory endurance (Progressive Aerobic Cardiovascular Endurance Run; PACER), and motivation in middle-school students.
174 students attended baseline and posttests and change scores computed for each outcome. A MANOVA was employed to examine change score differences using follow-up ANOVA and Bonferroni post hoc tests.
MANOVA yielded a significant interaction for Grade × Gender × Group (Wilks's Λ = 0.89, P < .001). ANOVA for PA revealed significant differences between SPARK grades 6 and 7 (Mean Δ = 8.11, P < .01) and Traditional grades 6 and 8 (Mean Δ = -6.96, P < .01). ANOVA also revealed greater PACER change for Traditional boys in grade 8 (P < .01) and SPARK girls in grade 8 (P < .01). There were significant interactions with perceived competence differences between SPARK grades 6 and 8 (Mean Δ = 0.38, P < .05), Enjoyment differences between SPARK grades 6 and 7 (Mean Δ = 0.67, P < .001), and SPARK grades 6 and 8 (Mean Δ = 0.81, P < .001).
Following the intervention, SPARK displayed greater increases on PA and motivation measures in younger students compared with the Traditional program.
本研究旨在探讨为期9周的SPARK项目对中学生身体活动(PA)、心肺耐力(渐进性有氧心血管耐力跑;PACER)和动机的影响。
174名学生参加了基线测试和后测,并计算了每个结果的变化分数。采用多变量方差分析(MANOVA),通过后续的方差分析(ANOVA)和Bonferroni事后检验来检验变化分数的差异。
多变量方差分析得出年级×性别×组别的显著交互作用(威尔克斯Λ = 0.89,P <.001)。对身体活动的方差分析显示,SPARK项目的6年级和7年级之间存在显著差异(平均变化量 = 8.11,P <.01),传统项目的6年级和8年级之间也存在显著差异(平均变化量 = -6.96,P <.01)。方差分析还显示,传统项目的8年级男生(P <.01)和SPARK项目的8年级女生(P <.01)的PACER变化更大。在SPARK项目的6年级和8年级之间,感知能力差异存在显著交互作用(平均变化量 = 0.38,P <.05);在SPARK项目的6年级和7年级之间,享受程度差异存在显著交互作用(平均变化量 = 0.67,P <.001);在SPARK项目的6年级和8年级之间,享受程度差异也存在显著交互作用(平均变化量 = 0.81,P <.001)。
干预后,与传统项目相比,SPARK项目在较年轻学生的身体活动和动机测量指标上有更大的提升。
