Optimal Ankle Axis Position For Articulated Footwear, Dustin A. Bruening, James G. Richards

Faculty Publications

An articulated boot design is commonly used in skiing and skating sports because it allows sagittal plane ankle mobility while still providing critical frontal plane stability. Although articulated boots have been in use for several decades, current manufacturers of these boots differ in their articulation placement. In this study we determined an optimal position of the ankle articulation axis. We also calculated the amount of anterior skin movement that a boot tongue must account for during a full range of ankle motion. Three‐dimensional kinematic data were collected and analyzed from 40 participants moving their right foot through a full range …

A Social Cognitive Perspective Of Physical-Activity-Related Behavior In Physical Education, Jeffrey J. Martin, Pamela Hodges Kulinna

Kinesiology, Health and Sport Studies

The purpose of the current study was to examine student and teacher physical-activity-related behavior using the theory of planned behavior and self-efficacy theory. Although teachers reported an overwhelmingly positive attitude toward teaching physical activity lessons to promote fitness development, they only devoted 4% of their class time to actually demonstrating and promoting fitness. Students were quite sedentary during class spending 61% of class time sitting, standing, or lying down. Using hierarchical regression analyses, teachers' attitudes toward teaching physically active physical education classes accounted for 50% of the variance in teachers' intention. Teachers who demonstrated/promoted fitness and who limited their general …

Effects Of Gender And Hypovolemia On Sympathetic Neural Responses To Orthostatic Stress, Qi Fu, Sarah Witkowski, Kazunobu Okazaki, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

We tested the hypothesis that women have blunted sympathetic neural responses to orthostatic stress compared with men, which may be elicited under hypovolemic conditions. Muscle sympathetic nerve activity (MSNA) and hemodynamics were measured in eight healthy young women and seven men in supine position and during 6 min of 60° head-up tilt (HUT) under normovolemic and hypovolemic conditions (randomly), with ∼4-wk interval. Acute hypovolemia was produced by diuretic (furosemide) administration ∼2 h before testing. Orthostatic tolerance was determined by progressive lower body negative pressure to presyncope. We found that furosemide produced an ∼13% reduction in plasma volume, causing a similar …

Lower Extremity Motion Analysis Patterns During Various Foot-Landing Styles, Nelson Cortes

Human Movement Studies & Special Education Theses & Dissertations

Walking, running, and jumping are considered essential human movement activities that occur on a daily basis. In every landing task, the lower extremity needs to dissipate and absorb the energy that is created by the landing height. In addition, more dissipation is normally needed when landing from higher jumps, which increases the work that needs to be done by joints, muscles, and bones in order to prevent injury. Great amounts of load during a landing have the potential to induce injuries, particularly in the ankle and knee complex. In many sports, such as soccer, basketball, football, and volleyball, there is …

The National Weight Control Registry: Is It Useful In Helping Deal With Our Obesity Epidemic?, James O. Hill, Holly Wyatt, Suzanne Phelan, Rena Wing

Kinesiology and Public Health

The National Weight Control Registry (NWCR) consists of over 4800 individuals who have been successful in long-term weight loss maintenance. The purpose of establishing the NWCR was to identify the common characteristics of those who succeed in long-term weight loss maintenance. We found very little similarity in how these individuals lost weight but some common behaviors in how they are keeping their weight off. To maintain their weight loss NWCR participants report eating a relatively low-fat diet, eating breakfast almost every day, weighing themselves regularly, and engaging in high levels (about 1 hour/day) of physical activity. Because this is not …

The Effects Of Choice On Student Motivation And Physical Activity Behavior In Physical Education, Jillian Ward

Theses and Dissertations

Public school physical educators have the opportunity to help students understand the importance of engaging in regular physical activity in order to combat America's obesity problem. However, students are often unmotivated to participate in their physical education classes. Providing students with an autonomy supportive environment increases intrinsic motivation. Self-determination theory states that higher levels of intrinsic motivation should lead to an increase in behavior, or higher activity levels in a physical education class. This study examined (a) the effects of increased autonomy on self-determination, and (b) the effects of increased autonomy on physical activity levels. Seventh and eighth grade girls …
