background: the present study was conducted to investigate the possible effects of l-carnitine and glutamine and their synergistic effects on male soccer athletes. methods: 28 male soccer players (21.1 ± 0.7 y) were enrolled in a randomized pre and post intervention, double-blind design. before the intervention, their performances were assessed by bruce protocol, and their body composition was ...

Women have smaller airways and lung volumes and lower resting maximal expiratory flow rates relative to men. Female athletes develop expiratory flow limitation more frequently than male athletes, and they have greater increases in end-expiratory and end-inspiratory lung volume at maximal exercise. Women use a greater fraction of their ventilatory reserve and have a higher metabolic cost of brea...

The majority of injuries sustained by female athletes are due to participation in sports rather than their sex. Anatomic, hormonal,and functional differences should be understood when treating the female athlete. Screening should be done for eating disorders and the female athlete triad. Female athletes have increased rates of injury to the anterior cruciate ligament and patellofemoral disorder...

OBJECTIVE To determine the association of quadriceps and hamstrings strength to anterior cruciate ligament (ACL) injury risk in female athletes. The primary hypothesis was that there would be decreased knee flexor and increased knee extensor strength in female athletes who went on to ACL injured status (FACL) compared to uninjured female (FC) and male (MC) control subjects. STUDY DESIGN Match...

OBJECTIVES Anecdotally many athletes report worse sleep in the nights prior to important competitions. Despite sleep being acknowledged as an important factor for optimal athletic performance and overall health, little is understood about athlete sleep around competition. The aims of this study were to identify sleep complaints of athletes prior to competitions and determine whether complaints ...

CONTEXT Although overuse injuries are gaining attention, epidemiologic studies on overuse injuries in male and female collegiate athletes are lacking. OBJECTIVE To report the epidemiology of overuse injuries sustained by collegiate athletes and to compare the rates of overuse and acute injuries. DESIGN Descriptive epidemiology study. SETTING A National Collegiate Athletic Association Divi...

BACKGROUND Despite the importance of body composition in athletes, reference sex- and sport-specific body composition data are lacking. We aim to develop reference values for body composition and anthropometric measurements in athletes. METHODS Body weight and height were measured in 898 athletes (264 female, 634 male), anthropometric variables were assessed in 798 athletes (240 female and 55...
