Description
This study examines the effectiveness of two modes of exercise on depression in adolescents with Down syndrome (DS). Thirty nine participants were randomly divided into a voluntary cycling group (VC) (i.e., self-selected cadence), an assisted cycling group (AC) (i.e., at least 30% faster than self-selected cadence accomplished by a motor), or a no exercise group (NC). In each cycling intervention the participant completed 30 minute cycling sessions, three times per week for a total of eight weeks. The Children's Depression Inventory II was administered prior to cycling (i.e., pretest) and after the eight week intervention (i.e., posttest). Although the data did not reach conventional levels of statistical significance, the results of the study demonstrated partial support for our hypothesis that adolescents with DS showed improvements in depression as measured by the Children's Depression Inventory II following assisted cycling, but not following eight weeks of voluntary cycling. In other words, eight weeks of moderate AC exercise demonstrated a trend for improved depression in adolescents with DS.

Description
Dietary supplement (DS) use among adults is on the rise. This growing trend in DS use mirrors the quick and exponential growth of the fitness industry. The fitness industry focuses on the “appearance of health”, although some individuals focus on their appearance over and above their health. As a result of this focus on appearance, certain aspects of this unregulated industry promote unhealthy standards of beauty and an increase in negative body image, and influences at-risk youth to engage in dangerous practices such as extreme diet and exercise routines, or the misuse of dietary supplements. All of these factors have been linked to appearance and performance enhancing drug use, which is associated with substance use in athletes and non-athletes. This study sought to explore the role of gender as it pertained to dietary supplement use, specifically how gender differences amongst predictors of DS use (including BMI, physical activity, and body image) were associated with overall substance use in college students. The relationship between current DS use and other substance use was also examined. Students recruited from ASU fitness centers completed a survey which included questions on demographics, height and weight to calculate BMI, and several published, standardized questionnaires used to measure drug use, physical activity, body image, steroid and ephedrine use and attitudes, and dietary supplement use. There were significant gender differences in DS use as well as predictors or DS use. Controlling for demographic information, energy enhancing DS use and knowing someone who used steroids increased the likelihood an individual intended on using steroids in the future. Body image was not related to substance use in males, and physical activity mediated the relationship between DS use and substance use in males. While body image was associated with substance use in females, neither physical activity nor body image mediated the relationship between DS use and substance use in females.
