Randomized Controlled TrialBurn and earn: a randomized controlled trial incentivizing exercise during fall semester for college first-year students.
To examine the viability of monetary incentives to increase fitness-center use and maintain/improve the Body Mass Indexes (BMIs) of first-year students over the fall semester. ⋯ Weekly monetary incentives resulted in significantly more first-year students meeting weekly fitness-center use goals. However, the increased fitness-center use by the incentive condition did not prevent an increase in BMI during fall semester.

Review Meta AnalysisA systematic review and meta-analysis of interventions designed to increase moderate-to-vigorous physical activity in school physical education lessons.
Physical education (PE) that allows students to engage in moderate-to-vigorous physical activity (MVPA) can play an important role in health promotion. Unfortunately, MVPA levels in PE lessons are often very low. In this review, we aimed to determine the effectiveness of interventions designed to increase the proportion of PE lesson time that students spend in MVPA. ⋯ Given the small number of studies, moderate-to-high risk of bias, and the heterogeneity of results, caution is warranted regarding the strength of available evidence. However, this review indicates that interventions can increase the proportion of time students spend in MVPA during PE lessons. As most children and adolescents participate in PE, these interventions could lead to substantial public health benefits.
