CONTEXT Sports nutrition experts recommend that team-sport athletes participating in intermittent high-intensity exercise for ≥1 hr consume 1-4 g carbohydrate/kg 1-4 hr before, 30-60 g carbohydrate/hr during, and 1-1.2 g carbohydrate/kg/hr and 20-25 g protein as soon as possible after exercise. The study objective was to compare observed vs. recommended macronutrient intake of competitive athle...

BACKGROUND When landing from a jump, the production of increased intersegmental knee abduction moments and coupled valgus motions has been associated with an increased risk of suffering a noncontact anterior cruciate ligament (ACL) injury in one study. This research has led to the development of a clinic-based algorithm that utilizes measures of knee valgus motion, knee flexion range of motion,...

It has been reported that the prevalence of amenorrhea in the general female population is 2-5% in young adult women, while this can be as high as 66% in certain sports events. Many investigations have found that prolonged amenorrhea in female athletes is associated with a reduction in bone mineral density (BMD). As exercise is an osteogenic stimulus in itself, it is possible that some bone los...

Taekwondo and judo competitions are divided into weight categories. Many athletes reduce their body mass a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast body mass reduction, athletes use a number of nutritional strategies, including choline supplementation. The goal of this study was to identify the effects of choline supplementat...

The purpose of this study was to identify factors related to the onset of eating disorders in female athletes. Participants were 17 collegiate female athletes (mean age of 20.7) who experienced eating disorders. Participants were interviewed individually and responses were coded thematically. Results revealed internal and external factors related to the onset of eating disorders. Internal facto...

The aim of this study was to compare feeling of loneliness between athlete and non-athlete university female students. The sample of the research consisted of 220 university female students, including 73 non-athletes who did not have any experience of sport participation and were randomly selected from the students of general physical education course in eleventh region of Islamic Azad Universi...

Female athletes participating in high-risk sports suffer anterior cruciate ligament (ACL) knee injury at a 4- to 6-fold greater rate than do male athletes. ACL injuries result either from contact mechanisms or from certain unexplained non-contact mechanisms occurring during daily professional sports activities. The occurrence of non-contact injuries points to the existence of certain factors in...

OBJECTIVE To determine the within subject (day to day) variability for variables reflecting iron status (concentrations of ferritin and soluble transferrin receptor (sTfR), and the sTfR/logFerr index) in female athletes during a training camp, and in female control subjects. RESULTS The error for ferritin concentration was nearly twice as high in athletes as in controls, that for sTfR concent...

The recent literature has focused on the need for appropriate identification, assessment, and management of sports-related concussion. This article addresses current issues in the prevalence and assessment of sports-related concussion. Despite a paucity of research on female athletes and youth athletes, there is evidence that female athletes are at higher risk for injury than males and that con...
