Issues In Quantifying Variability From A Dynamical Systems Perspective, Joseph Hamill, William J. Mcdermott, Jeffrey M. Haddad

Joseph Hamill

Variability is a critical aspect of a dynamical systems analysis. Because there are a number of numerical techniques that can be used in such an analysis, the calculation of variability has several issues that must be addressed. The purpose of this paper is to present a variety of quantitative methods for investigating variability from a dynamical systems perspective. The paper is divided into two major sections covering discrete and continuous methods. Each of these sections is subdivided into two sections. Within discrete methods, we discuss, first, the calculation of the discrete relative phase from a time-series history of two parameters …

Nutrition and Food Science Faculty Research Publications

Calcium β-hydroxy β-methylbutyrate (HMB) supplementation has been reported to reduce catabolism and promote gains in strength and fat free mass in untrained individuals initiating training. However, the effects of HMB supplementation on strength and body composition alterations during training in athletes is less clear. This study examined the effects of 28-d of calcium HMB supplementation during intense training on markers of catabolism, body composition, strength, and sprint performance. In a double-blind and randomized manner, 28 NCAA division I-A football players were matched-paired and assigned to supplement their diet for 28-d during winter resistance/agility training (~8 hr/wk) with a carbohydrate placebo …

Nike’S Commercial Solution: Girls, Sneakers, And Salvation, Shelley Lucas

Shelley Lucas

In this article I critically examine the ways in which Nike has situated itself as an active participant in current cultural conversations about girls' and women's participation in sport through three television commercials: `If you let me play', `There's a girl being born in America', and `The Fun Police'. In these advertisements, Nike positions itself as helping girls get a chance to play sports, helping them lead healthier and happier lives, helping them learn the rules of the game, and helping them to have fun. However, I argue that Nike's suggestion that girls can be empowered through sport (and through …

Relationship Between Reported Childhood And Adult Physical Activity, Kipp Ryan Kissinger

Student Work

It was the purpose of this research to examine the relationship between reported childhood and adult physical activity (PA), with special regards to the types of activities that correlate with habitual activity. Subjects were 249 male and female students age 19 to 30 years (M = 21.9 years) enrolled at the University of Nebraska at Omaha. Subjects were surveyed from all departments on campus. Subjects were asked to complete a survey instrument that assessed past and present PA. The results o f the current study reported that there is a significant positive correlation (r = 0.284, p < 0.05) between the total score of past childhood PA and present adult PA. When past PA was divided into preteen and adolescent periods, there were also significant relationships (p < 0.05) with all of the four indices of present PA (work, sport, leisure and total). Regression analysis explained 17.6 % of the variance in exercise when predicting adult PA from the total score of past PA. The prediction equation is as follows: Y ' = 27.761 + 0.775 (Xi) + 0.276 ( X 2 ) + 0.945 ( X 3 ) + 1.787 (3Ct) - 1.254 ( X 5 ) ; where Xi = number o f varsity athletic letters received as an adolescent, X 2 = informal activities as a preteen, X 3 = level of athletic ability or coordination in favorite sport as an adolescent, X4 = P.F.. classes as an adolescent, and X5 = activity level compared to peers as a preteen. It was concluded that there was a significant positive correlation (p < 0.05) between the total score of past PA and each of the four indices of present PA.

Mechanical Modeling Of Tibial Axial Accelerations Following Impulsive Heel Impact, David M. Andrews, Jj Dowling

Human Kinetics Publications

A fourth order mass/spring/damper (MSD) mechanical model with linear coefficients was used to estimate axial tibial accelerations following impulsive heel impacts. A generic heel pad with constant stiffness was modeled to improve the temporal characteristics of the model. Subjects (n = 14) dropped (~5 cm) onto a force platform ­(3 trials), landing on the right heel pad with leg fully extended at the knee. A uni-axial accelerometer was mounted over the skin on the anterior aspect of the medial tibial condyle inferior to the tibial plateau using a Velcro™ strap (normal preload ~45 N). Model coefficients for stiffness (k1, k2) …

Socialization Of Prospective Physical Education Teachers: The Story Of New Blood, Camille P. O'Bryant, Mary O'Sullivan, Jeanne Raudensky

Kinesiology and Public Health

There has been much criticism of how teachers are prepared to teach and physical education has not been immune from this criticism. Despite numerous efforts to improve the content and focus of teacher education programmes there is still a paucity of programme evaluation research on the efficacy of these teacher education programmes (Metzler & Tjeerdsma, 1998). This paper reports on part of a yearlong investigation on the efficacy of a graduate physical education teacher education programme to prepare teachers. The focus of this aspect of the study was to identify what attracted graduate students to pursue a teaching career and …

Recycling Of Deuterium From Dideuterated Glucose During Moderate Exercise, Michael A. Horning, Sheri R. Colberg, Gretchen A. Casazza, George A. Brooks

Educational Foundations & Leadership Faculty Publications

A doubly labelled tracer molecule of glucose, [6,6^-2HJglucose, has been used to measure the rate of glucose appearance in blood due to endogenous glucose production (by the liver and kidneysj.^l,2 Considered 'non-recirculating', this tracer generally provides a realistic estimate of glucose kinetics.^2,3 Used as a dual tracer in conjunction with [l-¹³C]glucose, the extent of glucose recycling can be quantitated.^2-4 but the extent of possible recirculation of a single deuterium atom on newly formed glucose must then be considered.

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.
