This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Bone is a dynamic, living tissue that can respond to mechanical stress, muscular activity, and strengthen over time. It is constantly broken down and rebuilt in a process known as remodeling. When slightly less bone is deposited than resorbed, it results in osteopenia and eventually osteoporosis, which predisposes the bone to fracture during minimal trauma. Osteoporosis is a condition of generalized skeletal fragility, or "weak bones". According to the Canadian Healthy Aging questionnaire in 2009, 19.2% of women reported being diagnosed with osteoporosis. With the rise of the aging population, the prevalence and cost of osteoporosis is sure to increase as well. The best method of preventing osteoporosis is building strong bones from a young age. Exercise can be used as a factor to build stronger bones at any age. Percussive activity has been shown to lead to increased bone mineral density (BMD), which explains why female athletes tend to have higher BMD than age-matched sedentary controls. This thesis presents a study comparing the BMD of female athletes in hockey and synchronized swimming to sedentary controls. 70 participants, 24 hockey players, 20 synchronized swimmers, and 26 sedentary controls participated in this study. Participants underwent three DXA scans (one total body and two regional scans) and answered a questionnaire about their menstrual history. BMD values were analyzed using ANCOVA controlling for age and weight. Predictors of BMD were also analyzed using step-wise regression. A significant difference in BMD at the level of the trochanter (F(2,65) = 5.47, p

This book was released on 1999 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background. Although weight-bearing exercise among previously sedentary adult females can increase bone mineral density (BMD), cross-sectional studies suggest that high-intensity exercise among amenorrheic athletes may be detrimental to bone health. The long-term effects of athletic participation on BMD should be examined. Objectives. This study was designed to: (1) Determine the prevalence of varsity athletic participation among female university graduates who participated in a mail survey; and, (2) Compare BMDs of high school varsity female athletes with women who were sedentary during the same time period, while controlling for covariates. Methods. A survey was mailed to 7291 alumnae of 2 Southern California universities in the classes of 1987-1991. The survey was returned by 1900 (26.1 %), and 1373 (72.3%) consented to further contact. Of the latter, 73 athletes (70.6% of those eligible) and 67 controls (53.1 % of those eligible), all 30-35 years of age, in a clinic evaluation, provided their health histories, anthropometric measurements, physical activity and dietary assessments, and dual energy x-ray absorptiometer measurements of the hip and spine. Results. Athletes were taller (p

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Physical activity, adequate energy, calcium and vitamin D intake all influence bone mineral density (BMD) in young adult females. Unfortunately, it is common to see nutrition deficiencies in this population that may put them at risk for a variety of health issues including lower BMD. Purpose: To determine the influence of the type of sport on regional and total BMD and its association with dietary energy, vitamin D and calcium intake. Methods: Seventy-three female students from McGill University were evaluated (average age of 20.8 years old, height 167.4 cm, weight 62.3 kg, and BMI 22.4). Forty-four athletes of 4 different Varsity Teams: basketball (n=13), volleyball (n=11), figure skating (n = 13), and synchronized swimming (n=7); and 29 age-matched sedentary students took part in the investigation. Dietary intake, Vitamin D and Calcium intake were assessed using a 3-day Food Log and a FFQ (short version) then analysed with the Food ProcessorTM Software. Total Body (TB), lumbar spine (LS) (L1-L4) and femoral neck (FN) BMD were assessed by DXA scanning. A one-way ANOVA explored between-group differences. Linear Regression Analysis, Pearson Correlations and ANCOVA were used to explore the influence of energy, Vitamin D and Calcium intake on BMD. Results: A significant difference in BMD at all 3 sites was observed across sports (TB = F(4,72) = 10.2, p

This book was released on 2019 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diet and physical activity are two modifiable factors that can curtail the development of osteoporosis in the aging population. One purpose of this study was to assess the differences in dietary intake and bone mineral density (BMD) in a Masters athlete population (n=87, n=49 female; 41.06 ± 5.00 years of age) and examine sex- and sport-related differences in dietary and total calcium and vitamin K intake and BMD of the total body, lumbar spine, and dual femoral neck (TBBMD, LSBMD and DFBMD, respectively). Total calcium is defined as calcium intake from diet and supplements. Athletes were categorized as participating in an endurance or interval sport. BMD was measured using dual-energy X-ray absorptiometry (DXA). Data on dietary intake was collected from Block 2005 Food Frequency Questionnaires (FFQs). Dietary calcium, total calcium, or vitamin K intake did not differ between the female endurance and interval athletes. All three BMD sites were significantly different among the female endurance and interval athletes, with female interval athletes having higher BMD at each site (TBBMD: 1.26 ± 0.10 g/cm2, p

This book was released on 2021 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sports participation is associated with adaptations in bone strength that reflects positively on bone mineral density (BMD). Although this participation has been positively associated with increased BMD, there is substantial heterogeneity in the osteogenic response from the various types of physical loading (e.g., gravitational loading, muscle loading) that are within sports. Therefore, the purpose of the current investigation is to determine the most influential predictive factors of BMD using anthropometric and performance-based assessments, as well as to compare BMD values between sports containing components of gravitational loading (GL) and muscle loading (ML) in Division-I female collegiate athletes. The results of this study suggest that the influence of various anthropometric and performance-based factors on BMD in female collegiate athletes, depends on the type mechanical loading that is performed during sport participation. While weight was reported to be the most influential factor for BMD in GL sports, extracellular fluid was the most influential factor for ML sports.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book of its kind to focus solely on the female athlete triad - its origins, its recognition, and most importantly, its management. Since the symptoms themselves cover a range of medical specialties, chapters are written by experts in a number of relevant fields - sports medicine, orthopedics, endocrinology, and pediatrics - with an eye toward overall care of the young female athlete. Additionally, each chapter includes suggestions on how to educate and communicate with young athletes and their parents, as well as trainers and coaches, on how to manage the illness outside of the direct clinical setting. The female athlete triad is often seen in sports where low body weight is emphasized, such as gymnastics, figure skating, and running, though it can appear in any sport or activity. The interrelated symptoms - eating disorders, amenorrhea, and low bone mass - exist on a spectrum of severity and are serious and potentially life-threatening if not properly treated. Psychological problems, in addition to medical ones, are not uncommon. The Female Athlete Triad: A Clinical Guide discusses all of these areas for a well-rounded and in-depth approach to the phenomenon and will be a useful reference for any clinician working with female athletes across the lifespan.

Download or read book The Relationship of Dietary Intakes of Calcium, Magnesium, and Zinc on Body Composition in Female and Male Athletes of Various Sports written by Maria Sylvester Terry and published by . This book was released on 2019 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because athletes often seek to enhance their performance and body composition through nutrition, researchers must continue to investigate the current dietary consumption and the relationship of diet to body composition to best individualize nutrition guidance for athletes. Exploration of sex differences and sport specific differences in dietary intake provides insight on possible nutrition trends in specific athlete populations and risks for deficiencies. Calcium, magnesium, and zinc affect physiological mechanisms and systems needed for athletic performance, such as calcium for bone health; magnesium for energy production; and, zinc for the function of hundreds of enzymes and proteins. One purpose of our research was to determine the dietary intake of calcium, magnesium, and zinc in female and male athletes, including runners, triathletes, rowers, CrossFit athletes, and General athletes, 18 years of age and older. We also investigated the presence of sex differences and sport specific differences in dietary intake of these minerals. Finally, we examined possible correlations among these mineral intakes and body composition (bone mineral density [BMD] and percent body fat) to determine the strongest predictors of body composition. We evaluated the dietary intake and body composition of 247 athletes, 129 women and 118 men, with a mean age of 34.86±11.38 years. The population included runners (n=90), General athletes (n=59), triathletes (n=43), rowers (n=34), and CrossFit athletes (n=21). Dietary intake was assessed via a 2005 Block Food Frequency Questionnaire (FFQ), which analyzes one's annual macronutrient and micronutrient intake. Bone mineral density (total body, lumbar spine, and dual femoral neck) and percent body fat were measured using dual-energy x-ray absorptiometry (DXA). One sample T-tests were used to compare the dietary intake of calcium, magnesium, and zinc to the Recommended Dietary Allowances (RDA) in female and male athletes. A one-way analysis of variance (ANOVA) was used to determine differences in dietary intake between the sexes and among various sports. Multiple regression analyses were utilized to identify the strongest predictors for BMD and percent body fat. All data were analyzed using standard SPSS version 25 software, with the alpha a priori set at 0.05. We found that across all female athletes, dietary intake of calcium was significantly below the RDA of 1000 mg/day (801.3 mg/day ± 264.9, p

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Dietary supplements are increasing in popularity; individuals are looking beyond traditional methods of calorie restriction and exercise to improve health. Calcium is a critical nutrient for bone metabolism that has also been shown to enhance weight loss effects secondary to diet. PURPOSE: To determine whether eight months of calcium supplementation, in a liquid, shelf-stable form, increases bone mineral density or decreases body weight and/or body fat in free-living young adult women. METHODS: Volunteer subjects (n=42) were randomly assigned to a supplement group receiving 1,125 mg Ca2+/day (CA-BEV) or to a free-living control group (CON), which did not receive the supplement. At baseline and after the 8-month intervention (POST), dietary intake was assessed using 3-day diet records. Total body composition (body fat percentage, %FatTB; abdominal percentage fat, %FatAb; fat mass, FM; non-bone fat-free mass, FFM) and bone mineral density (lumbar spine and femoral neck; BMD) were measured via dual energy x-ray absorptiometry. Subjects also completed a sub-maximal treadmill exercise test to estimate respiratory fitness at baseline and POST. RESULTS: At POST, the CA-BEV group's calcium intake (1,868[plus or minus]941 mg/d) was significantly greater than (p
