An Investigation Of Humeral Stress Fractures In Racing Thoroughbreds Using A 3d Finite Element Model In Conjunction With A Bone Remodeling Algorithm, Ryan James Moore

Master's Theses

The humerus of a racing horse Thoroughbred is highly susceptible to stress fractures at a characteristic location as a result of cyclic loading. The propensity of a Thoroughbred to exhibit humeral fracture has made equines useful models in the epidemiology of stress fractures. In this study, a racing Thoroughbred humerus was simulated during training using a 3D finite element model in conjunction with a bone remodeling algorithm. Nine muscle forces and two contact forces were applied to the 3-dimensional finite element model, which contains four separate load cases representing fore-stance, mid-stance, aft-stance, and standing. Four different training programs were incorporated …

A Qualitative Study Of The Motivations Of Runners In A Cause-Based Marathon-Training Program, Karin Ann Jeffery

Master's Theses

In the late 1980s, the nonprofit sector within the United States introduced a new philanthropic paradigm, the cause-based fundraising endurance-training program. Participants in such programs raise funds for a charitable cause and, in return, are coached to complete a marathon or other endurance event.

Cause-based training programs frequently use recruitment messages implying that the cause provides a guaranteed motivation to exercise. However, little research has examined this assumption. Therefore, the purpose of this study was to qualitatively research the motivations of runners in a charitable cause-based marathon-training program, particularly the relationship between the cause and the participants' motivations to train …
