Phase Determination During Normal Running Using Kinematic Data, Alan Hreljac, Nikolaos Stergiou

Journal Articles

Algorithms to predict heelstrike and toe-off times during normal running at subject-selected speeds, using only kinematic data, are presented. To assess the accuracy of these algorithms, results are compared with synchronised force platform recordings from ten subjects performing ten trials each. Using a single 180Hz camera, positioned in the sagittal plane, the average RMS error in predicting heelstrike times is 4.5 ms, whereas the average RMS error in predicting toe-off times is 6.9ms. Average true errors (negative for an early prediction) are +2.4 ms for heelstrike and +2.8ms for toe-off, indicating that systematic errors have not occured. The average RMS …

Fine-Tuning The Exercise Formula, David Swain

Rehabilitation Sciences Faculty Publications

(First paragraph) One hundred years ago, our forebears consumed more calories than we do today, yet they were leaner. Labor-saving devices were a rarity, and so in everyday life most people worked very hard physically. Obesity was present, of course, but afflicted only a small fraction of the population. We are not as fortunate today.

Asynchrony Between Subtalar And Knee Joint Function During Running, Nikolaos Stergiou, Barry T. Bates, Stanley L. James

Journal Articles

Purpose: It has been suggested that during running proper coordination between subtalar joint pronation/supination and knee joint flexion/extension via tibial rotation is important to attenuate ground reaction impact forces (GRIF). Lack of coordination may produce over time a wide range of injuries. The goal of this study was to investigate the relationship between subtalar pronation/supination and knee flexion/extension with GRIF increases during distance running.

Methods: Eight subjects ran under different speeds (a self-selected pace, 10% faster, 10% slower, and 20% faster) and over different obstacle heights (5%, 10%, and 15% of their standing height) on their self-selected pace. …

A Pilot Study Of Exercise Training To Reduce Trunk Fat In Adults With Hiv-Associated Fat Redistribution, Ronenn Roubenoff, Lauren Weiss, Ann Mcdermott, Tanya Heflin, Gregory J. Cloutier, Michael Wood, Sherwood Gorbach

Kinesiology and Public Health

Body fat redistribution (‘lipodystrophy’), with gain in abdominal and trunk fat, and decline in facial and limb fat, is a newly recognized problem in patients with HIV infection that has been linked to use of HIV-1 protease inhibitors. Increased abdominal fat may predispose these patients to hypertension, diabetes, and coronary artery disease. At this time no effective treatment is available. We examined whether exercise training could reduce trunk fat in men with fat redistribution.

Creatine Supplementation Differentially Affects Maximal Isometric Strength And Time To Fatigue In Large And Small Muscle Groups, William J. Vincent, Steven F. Loy, Richard L. Urbanski, Ben B. Yaspelkis

Faculty Publications

Ten physically active, untrained, college-aged males (26.4 ± 5.8 years old) received creatine (CR. 5 g creatine monohydrate + 3 g dextrose) and placebo (PLA, 7 g dextrose) supplementation four times per day for 5 days in a doubleblind, randomized, balanced, crossover design. Performance was assessed during maximal and three repeated submaximal bouts of isometric knee extension and handgrip exercise. CR supplementation significantly increased (p < .05) maximal isometric strength during knee extension but not during handgrip exercise. CR supplementation increased time to fatigue during each of the three bouts of submaximal knee extension and handgrip exercise when compared to the PLA trials. These findings suggest that CR supplementation can increase maximal strength and time to fatigue during isometric exercise. However, the improvements in maximal isometric strength following CR supplementation appear to be restricted to movements performed with a large muscle mass.

Stress And Burnout In Female High School Athletic Directors, Jeffrey J. Martin, Betty Kelley, Candice Dias

Kinesiology, Health and Sport Studies

In the current study we examined the relationships between stress predictors, stress, and burnout in female high school athletic directors (N = 52). Significant negative correlations between stress and hardiness and between stress and number of social support providers were found. Significant positive correlations between stress and time concerns, personnel concerns, and program success (e.g., winning) subscales of the athletic directing issues scale were also found. Subjects high in hardiness and with adequate social support networks, who also reported few athletic directing issues, were likely to report minimal stress. Significant positive correlations also indicated that stress was related to …

Methods: To estimate PAR, we employed a formula appropriate to use with an adjusted effect estimate. To estimate intermediate quantities needed to apply that formula, we used adjusted relative risk estimates from a previously published meta- analysis, as well as SEER cancer statistics and general population data from the third National …

Predictors Of Social Physique Anxiety In Adolescent Swimmers With Physical Disabilities, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

The purpose was to examine predictors of social physique anxiety (SPA) in adolescent swimmers with physical disabilities. Participants were 57 swimmers (27 females, 30 males, ages 16-19, M = 16.2) with various physical disabilities. A three-way ANOVA revealed significant differences in SPA between countries and among disabilities but not gender. Stepwise multiple regression results indicated that self-esteem and the self-identity subscale of the Athletic Identity Measurement Scale (AIMS) were the best predictors of SPA but that gender, country, and type of disability were not significant.

Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller

Dissertations and Theses @ UNI

The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …
