BACKGROUND This study was designed to investigate differences in recovery in male and female soccer athletes. HYPOTHESES Soccer players with a history of concussion will perform worse on neurocognitive testing than players without a history of concussion. Furthermore, female athletes will demonstrate poorer performance on neurocognitive testing than male athletes. STUDY DESIGN Cohort study ...

INTRODUCTION Aerobic capacity of athletes is an important element of success in sports achievements. It is generally considered the best indicator of cardio respiratory endurance and athletic fitness. Body fat percentage affects VO2 max and thus the cardiovascular status of the athletes. The present study was undertaken to assess the VO2 max and body fat percentage in athletes. The secondary ob...

Effects of long-term exercise on volumetric bone mineral density (vBMD), bone mineral content, bone geometric properties, and the strength indexes of bone were examined in a cross-sectional study of athletes and controls. Tibias of 25 jumpers (13 women), 30 swimmers (15 women), and 25 controls (15 women), aged 18-23 yr, were scanned at midsite by using peripheral quantitative computed tomograph...

OBJECTIVE To present findings from a collaborative study with the National College Athletic Association regarding the prevalence of disordered eating among student athletes. METHOD 1,445 student athletes from 11 Division 1 schools were surveyed using a 133-item questionnaire. RESULTS Results indicated that 1.1% of the females met DSM-IV criteria for bulimia nervosa versus 0% for males. None...

OBJECTIVE To determine if approximate entropy (ApEn), a regularity statistic from non-linear dynamics, could detect changes in postural control during quiet standing in athletes with normal postural stability after cerebral concussion. METHODS The study was a retrospective, case series analysis of centre of pressure (COP) data collected during the Sensory Organization Test (SOT) from NCAA Div...

Athletes are at higher risk than the general population for eating disorders, and risk is heightened for athletes in thin-build sports, including track. Collegiate athletes are particularly vulnerable to disordered eating when the transition from home to the college environment adds to the stress of performance pressures and the high demands of the sport environment. Male and female athletes wh...

OBJECTIVE To describe the prevalence of symptoms of depression among competitive collegiate student athletes and examine the factors associated with symptoms of depression among this population. DESIGN A baseline survey of a prospective cohort study. SETTING The survey was administered at the preseason team meetings. PARTICIPANTS The sample included 257 collegiate student athletes (167 ma...

Background: The objective of this study was to assess bone mineral density (BMD) of the lumbar spine and the proximal femur in male and female athletes performing different high level sports, in unspecifically trained sport students and in untrained subjects. Methods: BMD of lumbar spine and proximal femur were measured by dual-energy-x-ray-absorptiometry in 209 female and 173 male subjects age...
