Protective Factors Of Low Bone Mineral Density: An Examination Between Two Samples Of Premenopausal Women, Charlene Norgan Radler, Christine M. Florez, Colin Wilborn, Lem Taylor, Ariane Hollub Secrest

International Journal of Exercise Science: Conference Proceedings

While minimal longitudinal data exists to support osteoporosis screening among premenopausal women, an increasingly modernized society may contribute to modifiable osteoporosis risk factors including poor nutrition and low physical activity. Evaluation of bone mineral density (BMD) and body composition differences in populations with varied levels of physical activity is of importance. PURPOSE: The purpose of the current research was to determine if there is a difference across body composition measurements including total lean mass, body mass index (BMI), and BMD among a subset of physically active premenopausal women (ACTIVE) at a small, southern Christian university compared to premenopausal women …

Bone Mineral Density In Weight-Bearing And Aquatic Athletes, Elizabeth Krauss, Kayla Stuckenberg, Hawley C. Almstedt

International Journal of Exercise Science: Conference Proceedings

Bone mineral density (BMD) is a measure of mineral deposit within the bone that can be used as an early-adulthood predictor for onset of osteoporosis. Type of exercise induces a stress-response which builds BMD. PURPOSE: Non-weight-bearing-athletes were compared to weight-bearing-athletes and controls to identify differences in bone health among groups. The participants were compared longitudinally to measure change in BMD overtime. This study was modeled after work by Taaffe et al. (1995) which concluded that female athletes who do not engage in weight-bearing-activities had lower BMD. METHODS: Height, weight, and calcium intake was collected for female students (20.0±1.3 years); 23 …

Gender Difference In The Relationship Of Fatigue Index, Anaerobic Power And Capacity To Body Composition And Bone Mineral Status In Non-Athletes, Ali Mossayebi, Jehu N. Apaflo, Joshua Labadah, Victoria Rocha, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

The fatigue index is considered an important indicator of anaerobic fitness. The lower the fatigue index, the greater the ability of the body to maintain its power output through an anaerobic performance. The Wingate test is widely used by coaches, athletes, and researchers to measure lower body power, anaerobic capacity, and fatigue index. Body composition is considered an important component of anaerobic fitness, it is not clear how gender may influence the relationship between body composition and anaerobic fitness. PURPOSE: The purpose of this study was to understand how gender may impact the relationship between body composition and anaerobic …

Examination Of Athlete Triad Symptoms Among Endurance-Trained Male Athletes: A Field Study, Erin M. Moore, Clemens Drenowatz, David F. Stodden, Kelly Pritchett, Thaddus C. Brodrick, Brittany T. Williams, Justin M. Goins, Toni M. Torres-Mcgehee

All Faculty Scholarship for the College of Education and Professional Studies

Background: Studies examining the physiological consequences associated with deficits in energy availability (EA) for male athletes are sparse.

Purpose: To examine male athlete triad components; low energy availability (LEA) with or without an eating disorder risk (ED), reproductive hormone [testosterone (T)], and bone mineral density (BMD) in endurance-trained male athletes during different training periods.

Methods: A cross-sectional design with 14 participants (age: 26.4 ± 4.2 years; weight: 70.6 ± 6.4 kg; height: 179.5 ± 4.3 cm; BMI: 21.9 ± 1.8 kg/m2) were recruited from the local community. Two separate training weeks [low (LV) and high (HV) training volumes] were used …

Estimating Body Mass Through Bone Mineral Density Studies Using Dexa (Dual-Energy X-Ray Absorptiometry), Kaitlin Harstine

Master's Theses

Identification of a decedent is one of the primary goals of forensic anthropologists. In order to do this, one must build a biological profile based on the remains that are provided. Sex, age, ancestry, and stature are four of the most common, however a fifth addition piece of information that could be beneficial is body mass. The goal of this research is to explore the relationship between bone mineral density (BMD) and body mass, using data collected from dual x-ray absorptiometry (DEXA) scans of 107 collegiate football athletes. Athletes are a good fit for this study because they have achieved …

Bone Mineral Density Among Men And Women Aged 35 To 50 Years, Martha A. Bass, Ankita Sharma, Vinayak K. Nahar, Stacy Chelf, Brittany Zeller, Linda Pham, M. Allison Ford

Faculty and Student Publications

© 2019 American Osteopathic Association. Context: Osteoporosis is characterized by low bone mineral density (BMD) and has been thought to only be a major health concern for postmenopausal women. However, osteoporosis and its risk factors have been greatly understudied in the middle-aged and male populations. Objective: To assess the likelihood of low BMD and its association with related risk factors in early–middle-aged (defined in this study as 35-50 years) men and women.Methods: Eligible men and women completed a questionnaire assessing calcium intake, hours per week of exercise, and other related risk factors associated with osteoporosis and osteopenia. The primary outcome …

The Physiological Effects Of A Cross Country Bike Ride On Novice Cyclists, Wade Weatherholt

Mahurin Honors College Capstone Experience/Thesis Projects

Purpose: The physiological responses and adaptations experienced by novices engaging in cross-country cycling have received little attention in the scientific literature. Such endeavors typically involve a sizeable increase in physical activity for most individuals, but the acute and chronic effects of such an endurance feat are not well understood. Similarly, research shows that experienced cyclists often demonstrate osteoporosis in the spine, linked to many years of training accompanied by little or no weight bearing stress upon the axial skeleton. Greater understanding of these issues is needed, as long distance cycling has increased in popularity in recent years, and exercise professionals …
