Description
This study examines the effect of exercise therapy on a stationary bike on cognitive function, specifically inhibition and set-switching, in adolescents with Down syndrome. 44 participants were randomly divided between the voluntary cycling therapy group (VCT) (i.e., self-selected cadence), assisted cycling therapy group (ACT) (i.e., 30% faster than self-selected cadence accomplished by a motor), and a control group (NC) in which the participants did not undergo any exercise therapy. Both cycling groups rode a stationary bicycle, for 30 minutes, three times a week, for eight-weeks. At the beginning (i.e., pretest) and end (i.e., posttest) of the eight-week session the participants completed tasks to evaluate their cognitive function. They completed three trials of the card sort test (i.e., set-switching) and three trials of the knock-tap test (i.e, inhibition) before and after eight-weeks of cycling therapy. The scores of these tests were analyzed using one-way ANOVA between groups and paired samples t-tests. The results showed that after eight-weeks of cycling therapy the participants in the VCT group performed worse in the knock-tap test, but improved in two trials of the card sort test. The results also showed that the participants in the ACT group performed worse after eight-weeks of exercise therapy in one trial of the card sort test. No significant changes were seen for the control group. Due to the fact that on average the participants in the VCT group cycled with a higher heart rate, our results suggest exercise that significantly elevates heart rate can improve cognitive function, specifically set-switching, in adolescents with Down syndrome.

Description
Winning records are critical to a team's morale, success, and future. As such, players need to perform their best when they are called into a game to ensure the best possible chance of contributing to the team's success. During the 2013 fall season of Arizona State's NCAA soccer team, twenty-five females had quantities measured, such as heart rate workload, weight loss and playing time, that were analyzed using a least squares regression line and other mathematical relationships with mathematical software. Equations and box plots were produced for each player in the hopes that the coaches could tailor practices to the athletes' bodies needs to increase performance and results for the upcoming fall 2014 season. The playing time and heart rate workload model suggests that increased playing time increases heart rate workload in a linear fashion, though the increase varies by player. The model for the team proposes that the heart rate workload changes in response to playing time according to the equation y=2.67x+127.41 throughout the season. The weight loss and heart rate workload model suggest that establishing a relationship between the two variables is complex since the linear and power regression models did not fit the data. Future studies can focus on the Rate of Perceived Exertion scale, which can supplement the heart rate workload and provide valuable information on players' fatigue levels.
