Cardiorespiratory Fitness Reduces The Risk Of Incident Hypertension Associated With A Parental History Of Hypertension., Robin Shook, D. C. Lee, X. Sui, V. Prasad, S. P. Hooker, T. S. Church, S. N. Blair
Robin Shook
Family history of hypertension increases the risk of an individual to develop hypertension, whereas moderate-to-high cardiorespiratory fitness has the opposite effect. However, the joint association of each on the development of hypertension is not well understood. We studied fitness and incident hypertension in 6278 participants who were given a preventative medical examination. Thirty-three percent reported a parent with hypertension, and there were 1545 cases of incident hypertension after a mean of 4.7 years. The presence of parental hypertension was associated with a 28% higher risk of developing hypertension after adjustments for age, sex, and examination year. After further adjustments for …

Excess body weight is associated with an imbalance between energy expenditure and dietary intake but evidence on the association between diet quality and body composition remains equivocal. Rather than relying on differences in diet quality between overweight/obese and normal weight adults, this study examined the association between the Healthy Eating Index 2010 (HEI-2010) and body fatness on a continuous scale, independent of physical activity (PA). Further the association between components of the HEI-2010 and risk for overweight/obesity was explored. 407 adults (27.6 6 3.7 years) provided at least two 24-hour diet recalls over a period of 14 days, which were …

Robin Shook
OBJECTIVE: To determine whether moderate cardiorespiratory fitness (CRF) or moderate to vigorous physical activity (MVPA) is associated with elevations in resting metabolic rate (RMR) similar to findings previously observed in endurance athletes. PARTICIPANTS AND METHODS: Using a cross-sectional design, we measured CRF, RMR, body composition, energy expenditure, and time in MVPA via an arm-based activity monitor in 423 young adults (mean age, 27.6 years). Based on the results of a fitness test, participants were classified into CRF tertiles (low, moderate, or high) by sex. RESULTS: There were significant differences among the low-, moderate-, and high-CRF groups for mean ± SD …
Top 10 Research Questions Related To Energy Balance, Robin P. Shook, Gregory A. Hand, Steven N. Blair
Top 10 Research Questions Related To Energy Balance, Robin P. Shook, Gregory A. Hand, Steven N. Blair
Robin Shook
Obesity is the result of a mismatch between the amount of calories consumed and the amount of calories expended during an extended period of time. This relationship is described by the energy balance equation, which states the rate of change in energy storage depots in the body are equal to the rate of energy intake minus the rate of energy expenditure. Although this relationship may appear easy to understand based on simple mathematics, in reality, a variety of known and unknown systems influence the components of energy balance (energy storage, energy intake, energy expenditure). Clearly, if a complete understanding of …

Robin Shook
Context: Relationships between socio-environmental factors and obesity are poorly understood due to a dearth of longitudinal population-level research. The objective of this analysis was to examine 45-year trends in time-use, household management (HM) and energy expenditure in women. Design and Participants: Using national time-use data from women 19–64 years of age, we quantified time allocation and household management energy expenditure (HMEE) from 1965 to 2010. HM was defined as the sum of time spent in food preparation, post-meal cleaning activities (e.g., dish-washing), clothing maintenance (e.g., laundry), and general housework. HMEE was calculated using body weights from national surveys and metabolic …

The Effects Of Symmetric And Asymmetric Foot Placements On Sit-To-Stand Joint Moments, Jason C. Gillette, C. A. Stevermer
Jason C Gillette
The purpose of this study was to determine the effects of symmetric and asymmetric foot placements on joint moments during sit-to-stand movements. Three symmetric (foot-neutral, foot-back, and foot-intermediate) and three asymmetric foot placements (preferred stagger, nonpreferred stagger, and intermediate stagger) were tested. Standard (46 cm) and low (41 cm) seat heights were chosen to represent an average public seat height and a 10% lower seat height. Using inverse dynamics, maximum ankle plantarflexion, knee extension, hip extension, and hip abduction moments were calculated. Hip extension moments were significantly increased when using foot-neutral as compared to foot-back. Ankle plantarflexion and knee extension …

Gait Analysis Post Anterior Cruciate Ligament Reconstruction: Knee Osteoarthritis Perspective, M. Hall, C A. Stevermer, Jason C. Gillette
Jason C Gillette
Individuals with anterior cruciate ligament (ACL) reconstruction are at increased risk to develop knee osteoarthritis (OA). Gait analysis describing kinetics of the lower extremity during walking and stair use (stair ascent and stair descent) can provide insight to everyday dynamic knee joint loading. In this study, we compared lower extremity gait patterns of those with ACL reconstruction (>1 year) to a control group. Fifteen ACL reconstructed individuals and 17 healthy controls participated in this study. Knee extensor and flexor strength were assessed. Using inverse dynamics, lower extremity moments were calculated during the stance phase of walking and during two …

Elizabeth L. Stegemoller
Background: Gait performance is widely evaluated to assess health status in older adult populations. While several investigators have presented normative values for spatiotemporal gait parameters drawn from older adult populations, the literature has been void of large-scale cohort studies, which are needed in order to provide quantitative, normative gait data in persons with Parkinson’s disease. The aim of this investigation was to provide reference values for clinically important gait characteristics in a large sample of ambulatory persons with Parkinson’s disease to aid both clinicians and researchers in their evaluations and treatments of gait impairment. Methodology/Principal Findings: Gait performance was collected …
Perceptions Of Flatulence From Bean Consumption Among Adults In 3 Feeding Studies, Donna M. Winham, Andrea M. Hutchins
Perceptions Of Flatulence From Bean Consumption Among Adults In 3 Feeding Studies, Donna M. Winham, Andrea M. Hutchins
Donna Winham
Background: Many consumers avoid eating beans because they believe legume consumption will cause excessive intestinal gas or flatulence. An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks. Methods: Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to …

Tilapia: Profile And Economic Importance, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown
Kurt A. Rosentrater
Tilapia is the common name broadly applied to a group of cichlid fishes native to Africa, the Mediterranean, and the Middle East. Tilapia are some of the oldest cultured fishes, as depicted in line drawings found in Egyptian tombs that date back to 2000 BC. This group consists of three economically important genera, which are taxonomically distinguished according to their reproductive behaviors: Tilapia, Oreochromis, and Sarotherodon, all are commonly known as “tilapia.” Tilapia are biparental caring-substrate spawners; Oreochromis are generally maternal mouth brooders; and Sarotherodon are generally paternal or biparental mouth brooders. Currently, Nile tilapia (Oreochromis niloticus; fig. 1) and …

Tilapia: Environmental Biology And Nutritional Requirements, Kamal Mjoun, Kurt A. Rosentrater, Michael L. Brown
Kurt A. Rosentrater
Tilapia is one of the most widely cultured fish in the world. Currently, farmed tilapia represents more than 75% of world tilapia production (FAO, 2009), and this contribution has been exponentially growing in recent years. Several factors have contributed to the rapid global growth of tilapia. Tilapia are easily cultured and highly adaptable to a wide range of environmental conditions. Tilapia feed on a wide variety of dietary sources, including phytoplankton, periphyton, zooplanktons, larval fish, and detritus. Adult tilapia are principally herbivorous but readily adapt to complete commercial diets based on plant and animal protein sources. In the United States, …
Genetic Analysis Of The Federally Endangered Winged Mapleleaf Mussel To Aid Proposed Re-Introduction Efforts, Kevin J. Roe
Genetic Analysis Of The Federally Endangered Winged Mapleleaf Mussel To Aid Proposed Re-Introduction Efforts, Kevin J. Roe
Kevin J. Roe
The winged mapleleaf, Quadrula fragosa, historically occurred in the Mississippi, Tennessee, Ohio, and Cumberland river drainages, but has suffered severe population and range reductions. At the time that the species was federally listed as endangered, its range was thought to have been reduced to a stretch of the St. Croix River between northwestern Wisconsin and east-central Minnesota. Recently, morphologically “Q. fragosa-like” specimens were discovered at sites in Arkansas (Ouachita River and Saline River), Missouri (Bourbeuse River), and Oklahoma (Little River). Subsequently, a plan was proposed to re-introduce Q. fragosa into portions of its historic range where its been extirpated from …

Malnutrition, A Global Problem, Shirin Pourafshar, Kurt A. Rosentrater, Padmanaban Krishnan
Kurt A. Rosentrater
Malnutrition is a general term for medical conditions caused by an inadequate diet and poor nutrition. Hunger and malnutrition are among the major difficulties confronting many countries around the world. Malnutrition can be caused by several factors, such as the sharp increase in population (current world population is approximately 6,800,000,000), poor distribution of foods, lack of access to highly nutritious foods, and most important, lack of knowledge about healthy diets. Malnutrition can lead to other problems, such as reduced school attendance, learning capacity, spread of HIV/AIDS, malaria and other diseases, and it can have a negative effect on a nation’s …

Mycotoxins In Corn Distillers Grains: A Concern In Ruminants?, Alvaro Garcia, Kenneth Kalscheur, Arnold Hippen, David Schingoethe, Kurt A. Rosentrater
Kurt A. Rosentrater
Themain fungi that produce toxins during storage belong to three genera: Aspergillus, Fusarium, and Penicillium. When dealing with cattle diets, it is not easy to correlate the presence of mycotoxins to that of molds. The same types of molds can produce different types of toxins, and different types ofmolds can produce the samemycotoxin.

'Willa Cather’S ‘River Of Silver Sound’: Woman As Ecosystem In The Song Of The Lark, Matthew Sivils
'Willa Cather’S ‘River Of Silver Sound’: Woman As Ecosystem In The Song Of The Lark, Matthew Sivils
Matthew Sivils
Willa Cather loved the Southwest. The landscapes and cu ltural history of the area held a prominent place in both her fiction and in her own creative consciousness.1 As Judith Fryer points out, after Cather visited New Mexico and Arizona in 1912, she became so enamored with the region that she returned many times over the fol lowing decade (41). During this period Cather published a novel heavily inspired by her affection for the Southwestern landscape-The Song of the Lark. This novel fol lows Thea Kronborg from her childhood in the fictional rural town of Moonstone, Colorado, through an artistic …

Preliminary Exercise Identity Scale (Eis) Norms For Three Adult Samples, Dean F. Anderson, Charles M. Cychosz, Warren D. Franke
Warren D Franke
Sociological traditions suggest that role identities serve to give meaning and importance to past behavior as well as provide direction for future behavior. The Exercise Identity Scale (EIS) was developed to measure the extent to which exercise contributes to an individual's role-identity. This investigation examined age norms on the EIS. Data were collected from three populations including a convenience sample of 203 college students enrolled in three elective health-studies courses (92% Caucasian and 63% female), 441 of 531 (83%) law enforcement employees in a state department concerned with public safety (98% Caucasian and 96% male), and 1253 of 4000 (32%) …
Phylogeographic Analysis Of The Threatened And Endangered Superconglutinate-Producing Mussels Of The Genus Lampsilis (Bivalvia: Unionidae), Kevin J. Roe, Charles Lydeard, Paul D. Hartfield
Phylogeographic Analysis Of The Threatened And Endangered Superconglutinate-Producing Mussels Of The Genus Lampsilis (Bivalvia: Unionidae), Kevin J. Roe, Charles Lydeard, Paul D. Hartfield
Kevin J. Roe
Several species of freshwater unionid mussels in the genus Lampsilis exhibit a remarkable reproductive strategy. Female mussels of these species enclose their larvae in a minnow-like lure, called a ‘superconglutinate’, to attract piscivorous fishes. When a fish attempts to ingest the superconglutinate the lure ruptures and the larvae are released to parasitize the fish. Of the four species of mussel which exhibit this strategy and are endemic to the Gulf Coast drainages of the southeastern United States, three are protected under the Endangered Species Act, and one is recognized as imperilled. Phylogenetic analysis of nucleotide sequences of the mitochondrial 16S …

Association Of Exercise Identity With Measures Of Exercise Commitment, Dean F. Anderson, Charles M. Cychosz, Warren D. Franke
Warren D Franke
Role-identities are integral parts of the concept of self. Sociological traditions suggest that they serve to give meaning and importance to past behavior as well as providing direction for future behavior. This investigation examined the relationship of Exercise Identity with: age of subject, three measures of exercise commitment, and three physiological indicators of fitness. Data were collected from 448 of the 531 (84%) law enforcement personnel of a state department of public safety during annual physical exams at the university fitness clinic. Ninety-eight percent of the subjects self-identified as Caucasian and 96% were male (mean age = 39, range 21-63). …

Chivalry In Pholcid Spiders Revisited, Julie A. Blanchong, Michael S. Summerfield, Mary A. Popson, Elizabeth M. Jakob
Julie A. Blanchong
Cohabiting pairs of adult spiders are likely to interact over prey, and the outcome of these interactions is likely to affect the reproductive success of both individuals. In two species of pholcid spiders, previous workers reported the occurrence of "chivalrous" behavior, in which males cede prey to females. We looked for the occurrence of chivalrous behavior in another pholcid spider, Holocnemus pluchei. Pairs of spiders were placed on a web and left overnight without prey. A housefly was then introduced onto the web equidistant from the spiders, and subsequent interactions were noted on audiotape. We found no evidence of chivalry …
