Description
The benefits of exercise have been recommended in typical and other special populations. However, the evidence for persons with Down syndrome (DS) is still limited. This study was aimed at investigating the impact of an acute bout of aerobic exercise intervention on motor performance, executive function and intrinsic motivation in adolescents and young adults with DS. Ten participants with DS were assigned to an exercise group, who walked on a incremental treadmill protocol for 20 minutes. The exercise intensity was achieved at 66% of their predicted maximum heart rate. Another ten participants with DS were assigned to an attentional control group, who watched a video for 20 minutes. Measures of fine manual dexterity (e.g., Purdue Pegboard test), manual force production (e.g., grip strength test), processing speed (e.g., visual choice reaction time test), verbal processing (e.g., verbal fluency test), attention shifting ability (e.g., The Dimensional Card sorting test), and inhibitory control (e.g., Knock and Tap test) were tested pre and post intervention. An intrinsic motivation scale (e.g., enjoyment and effort) was conducted after the intervention. First, results showed participants significantly improved their performance in manual force production and Knock and Tap Test after the exercise intervention. While it has been proposed that exercise increases arousal status, neurotransmitters, or cerebral vasculature, the exact mechanisms in persons with DS are still unknown. However, our results showed that after treadmill walking, motor and cognitive improvements can be found in individuals with DS, even in a single exercise session. In addition, participants reported higher scores in enjoyment after video viewing than exercise, which may a result from musical effect or too much emphasis on external rewards in their early participation in exercise. These may imply that participants had low intrinsic motivation to an active lifestyle. Further, scores in effort were significantly higher after exercise than video viewing, which indicated their capabilities to perceive their physical exertion. However, other motivational regulations (e.g., introjected and identified regulations) have shown the relationship with exercise behavior in this population. Thus, further study should consider divergent motivational factors in order to implement an effective exercise program.

Description
Incentive travel continues to grow as a form of motivation in the work place. However, there is little research that has examined future potential incentive travelers' wants and needs from an incentive travel trip. The purpose of this study was to understand how and in what way various potential incentive travelers' beliefs, including attitudes, subjective norm, perceived behavioral control and motivation, influence their future inclusion of a significant other on an incentive travel trip using a modified theory of planned behavior. Moreover, the potential moderating effect of past inclusion of a significant other experience was examined as well. The study collected 129 usable responses from potential incentive travelers from companies based in Iowa and Arizona. The research for this project was conducted through online questionnaires that included quantitative and qualitative questions. The study used exploratory factor analysis (EFA), Pearson's correlation and multiple regression to test study hypotheses. The results of the multiple regression indicated three constructs, attitudes, subjective norm and motivation appeared to be statistically significant, while perceived behavioral control was not statistically significant in predicting potential incentive travelers' intended inclusion of a significant other. Perceived behavioral control was not significant because the control of including a significant other is dependent on the participant's employer. Pearson's correlation found a moderating effect of past inclusion of a significant other on subjective norm and perceived behavioral control. In conclusion, the results validated the theory of planned behavior in the context of incentive travelers' inclusion of a significant other.
