To test the effectiveness of an intervention to increase motivation for physical activity in racially diverse third- through fifth-grade students.
Natural experiment.
Elementary schools in Minneapolis, Minnesota.
Two hundred ninety-one students in 18 Minne-Loppet Ski Program classes and 210 students in 12 control classrooms from the same schools.
The Minne-Loppet Ski Program, an 8-week curriculum in elementary schools that teaches healthy physical activity behaviors through cross-country skiing.
Pretest and posttest surveys measured self-determination theory outcomes: intrinsic exercise motivation, intrinsic ski motivation, autonomy, competence, and relatedness.
Hierarchical linear regression models tested treatment effects controlled for grade, race, sex, and baseline measures of the outcomes.
Minne-Loppet program students showed significantly greater motivation to ski (β = 0.95, 95% confidence interval [CI]: 0.15-1.75) and significantly greater perceived competence (β = 0.78, 95% CI: 0.06-1.50) than students in control classrooms. Treatment effects for general exercise motivation and perceived competence differed by race. African American students in Minne-Loppet classes showed significantly greater general exercise motivation (β = 1.08, 95% CI: 0.03-2.14) and perceived competence (β = 1.95, 95% CI: 0.91-2.99) than African American students in control classes.
The Minne-Loppet program promoted perceived competence and motivation to ski. Future improvements to the Minne-Loppet and similar interventions should aim to build general motivation and provide support needed to better engage all participants.
测试一项干预措施对提高不同种族三至五年级学生体育活动积极性的有效性。
自然实验。
明尼苏达州明尼阿波利斯的小学。
18个明尼洛佩特滑雪项目班级的291名学生以及来自同一学校12个对照班级的210名学生。
明尼洛佩特滑雪项目,这是一项在小学开展的为期8周的课程,通过越野滑雪教授健康的体育活动行为。
前测和后测调查测量自我决定理论结果:内在运动动机、内在滑雪动机、自主性、能力和关联性。
分层线性回归模型测试了控制年级、种族、性别和结果基线测量值后的治疗效果。
与对照班级的学生相比,明尼洛佩特项目的学生表现出显著更高的滑雪动机(β = 0.95,95%置信区间[CI]:0.15 - 1.75)和显著更高的感知能力(β = 0.78,95% CI:0.06 - 1.50)。一般运动动机和感知能力的治疗效果因种族而异。明尼洛佩特班级中的非裔美国学生比对照班级中的非裔美国学生表现出显著更高的一般运动动机(β = 1.08,95% CI:0.03 - 2.14)和感知能力(β = 1.95,95% CI:0.91 - 2.99)。
明尼洛佩特项目提高了感知能力和滑雪动机。未来对明尼洛佩特项目及类似干预措施的改进应旨在培养一般动机,并提供更好地让所有参与者参与所需的支持。
