Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff
Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff
Theses and Dissertations
Preliminary testing of health behavior interventions (e.g., pilot, feasibility studies) are used to evaluate intervention viability prior to additional testing and resource investment (e.g., larger trials). This initial testing provides valuable information, but promising estimates of effectiveness produced during early testing are rarely reproduced in larger studies, stalling the development of effective, scalable health interventions. In the obesity intervention literature, external validity biases, features of the intervention that are not (or cannot) transfer to the larger study, are associated with these diminished effects. These study features, such who delivers the intervention, the characteristics of the population receiving the intervention or …
Kinematic Changes During A Marathon For Fast And Slow Runners, Maggie Man-Yee Chan-Roper
Kinematic Changes During A Marathon For Fast And Slow Runners, Maggie Man-Yee Chan-Roper
Theses and Dissertations
The purpose of this study was to describe kinematic changes that occur during an actual marathon. We hypothesized that (1) certain running kinematic measures would change between miles 5 and 25 of a marathon and (2) fast runners would demonstrate smaller changes than slow runners. Subjects (n = 179) were selected according to finish time (Range = 2:20:47 to 5:30:10). Two high-speed cameras were used to measure sagittal-plane kinematics at miles 5 and 25 of the marathon. The dependent variables were stride length, ground time, peak knee flexion during support and swing, and peak hip flexion and extension during swing. …
