[Bulimic behaviours in female adolescent endurance runners].
OBJECTIVE The aim of the present work is to evaluate bulimic behaviors among female adolescent endurance runners. METHODS From a total of 40 athletes affiliated to the Track and Field Federation of Rio de Janeiro, 17 female teenager endurance runners (age: 16+/-1,8 years) were examined. The instrument used to investigate bulimic behavior and its gravity was BITE (Bulimic Investigatory of Edin...
متن کاملPhysiological factors associated with low bone mineral density in female endurance runners.
OBJECTIVE To explore potential factors that could be associated with low bone mineral density (BMD) in female endurance runners. METHODS Fifty two female endurance runners (1,500 m to marathon), aged 18-44 years, took part. Body fat percentage, lumbar spine BMD, and femoral neck BMD were measured using the Hologic QDR 4,500w bone densitometer. Data on training, menstrual cycle status, osteopo...
متن کاملBone Mass, External Loads, and Stress Fracture in Female Runners
Increased incidence of stress fracture has been reported for amenorrheic runners, while some studies have reported decreased spinal bone mass in amenorrheic runners. Based on results from these studies, one tends to associate decreased spinal bone mass with an increased risk of stress fracture. The present study compared regional bone mass and external loads during running between six female ru...
متن کاملComparison of Site-Specific Bone Mineral Densities between Endurance Runners and Sprinters in Adolescent Women
We aimed to compare site-specific bone mineral densities (BMDs) between adolescent endurance runners and sprinters and examine the relationship of fat-free mass (FFM) and nutrient intake on BMD. In this cross-sectional study, 37 adolescent female endurance runners and sprinters (16.1 ± 0.8 years) were recruited. BMD and FFM were assessed by dual-energy X-ray absorptiometry. Nutrient intake and ...
متن کاملThe Effect of Ongoing Vitamin D and Low-Fat Milk Intake on Bone Metabolism in Female High-School Endurance Runners
Background Vitamin D and calcium are essential nutrients for bone health. In addition, vitamin D suppresses inflammatory cytokines and increases bone resorption. Therefore, improvements in bone health by calcium and vitamin D supplementation have the potential to not only improve calcium metabolism but also suppress inflammation associated with exercise training. The purpose of this study was t...
