The Estimation Of Caloric Expenditure Using Three Triaxial Accelerometers, Tyrone Gene Ceaser

Doctoral Dissertations

Accelerometer-based activity monitors are commonly used to measure physical activity energy expenditure (PAEE). Newly designed wrist and hip-worn triaxial accelerometers claim to accurately predict PAEE across a range of activities. Purpose: To determine if the Nike FuelBand (NFB), Fitbit (FB) and ActiGraph GT3X+ (AG) estimate PAEE in various activities. Methods: 21 healthy, college-aged adults wore a NFB on the right wrist, a FB on the left hip, and AG on the right hip, while performing 17 activities. AG data were analyzed using Freedson’s kcal regression equation. PAEE was measured using the Cosmed K4b² (K4). Repeated measures ANOVAs were used …

Adaptations Of Yoga: Christian Interpretations, Eleanor Freyhan Odenheimer

Doctoral Dissertations

The yogic phenomenon in the West is multi-dimensional and threads through areas of history (DeMichelis, 2008), market trends, fitness and exercise, medicine (Guarracino, Lazo, Savino, & Edelstein, 2006); religion and spirituality (DeMichelis, 2008); and health and wellness (Iyengar, 1989). Coakley (2004) called for “more information about the connections among various religious beliefs around the world, ideas of the body, and participation in physical activities and sports” (p. 543). A dearth of literature exists concerning the connections between how Christian beliefs, the dominant religion in the United States (Pew Research Center, 2008), related to the body and physical activity participation inform …

Helmet Use Among Outdoor Recreational Rock Climbers Across Disciplines: Factors Of Use And Non-Use., Kevin Henri Hogan Soleil

Masters Theses

The use of helmets in outdoor recreational rock climbing is a risk management practice meant to offer some protection to climbers in the event of falls and falling objects. Helmets are used inconsistently across many disciplines of rock climbing including top-rope, sport lead, traditional lead and belay. Though climbing accidents involving head injuries are rare, many tend to be severe. The purpose of this study was to assess the rate at which helmets are being used, discover the most significant personal and environmental factors that influence use and non-use and differences between disciplines. The study surveys (N = 1481) …

Biomechanical Differences Of Two Common Football Movement Tasks In Studded And Non-Studded Shoe Conditions On Infilled Synthetic Turf, Elizabeth Anne Brock

Masters Theses

The purpose of this study was to examine kinematic and kinetic differences in three shoe conditions (traditional football shoes with natural and synthetic turf studs and a neutral running shoe) during two common football movements (a 180° cut and a land-cut movement) on infilled synthetic turf. Fourteen recreational male football players performed five trials in all three shoe conditions for a 180° cut as well as a land-cut maneuver. The kinematic and kinetic variables were analyzed with a 3 x 2 (shoe x movement) repeated measures analysis of variance (ANOVA, p<0.05). Peak free moment was significantly greater for the land-cut trials (p<0.001). Vertical GRFs were significantly greater for the land-cut trials (p<0.001). A cleat x movement interaction was seen for time to vertical impact GRF (p=0.048). A cleat main effect was found for time to vertical impact between natural turf cleat and synthetic turf cleat (p=0.019). Vertical loading rate was significantly greater in land-cut trials. Peak medial GRFs showed a significant cleat x movement interaction (p=0.002). The results from this study suggest that land-cut movement elicit greater vertical GRF and vertical impact loadings rates. The running shoe had significantly less dorsiflexion range of motion (ROM) than the synthetic turf studs. A significant cleat main effect was found for peak eversion velocity (p=0.005). Post hoc comparisons showed that it was significantly smaller in shoe than that natural turf stud (p=0.016) and synthetic turf stud (p=0.002). In general, there was a lack of differences between the shoe conditions for GRFs and kinematic variables. For the 180° cut movement, natural turf studs produced lowest peak medial GRF compared to the synthetic turf studs and the shoe. The results from this study suggest that land-cut movement elicit greater vertical GRF and vertical impact loadings rates. In general, there was a lack of differences of GRFs and kinematic variables between the shoe conditions. For the 180° cut movement, natural turf studs produced lowest peak medial GRF compared to the synthetic turf studs and the shoe. Overall, increased GRFs, especially in combination with rapid change of direction and deceleration may increase the chance of injury.

A Description Of The Movement Of The Canine Pelvic Limb In Three Dimensions Using An Inverse Dynamics Method, And A Comparison Of Two Techniques To Surgically Repair A Cranial Cruciate Ligament Deficient Stifle, Jason Headrick

Doctoral Dissertations

The purposes of the dissertation were: 1) to describe three-dimensional (3D) motion of the canine pelvic limb using an inverse dynamics method, and 2) to compare these motion patterns between normal, healthy dogs and those that have had their stifles stabilized by one of two surgical methods approximately five years earlier.

Twenty-five dogs were allocated to three groups; healthy control dogs, dogs that had received the tibial plateau leveling osteotomy (TPLO), and dogs that had received the lateral fabellar suture (LFS) stabilization technique. Both surgical techniques were performed approximately five years prior on stifles with surgically induced cranial cruciate ligament …

“It Was Fight Or Flight...And Flight Was Not An Option”: An Existential Phenomenological Investigation Of Military Service Members’ Experience Of Hand-To-Hand Combat, Peter Richard Jensen

Doctoral Dissertations

Hand-to-hand combat is one of the more psychologically challenging performance environments for those in the military (Grossman, 1995). Even with the technological advances of modern warfare military leaders still believe hand-to-hand combat is an important and relevant challenge for service members (Blanton, 2007; Clark, 2009; Collins, 2007; Wojdakowski, 2007; Wood & Micaelson, 2000). Despite its importance, the hand-to-hand combat experience has, to date, attracted very little research attention. Therefore, the purpose of this study was to explore military service members’ experiences of hand-to-hand combat. To accomplish this objective, phenomenological interviews were conducted with 17 male military service members. Each participant …
