To evaluate the effects of long-term exposure to high-intensity training among professional runners on cardiac hypertrophy and subclinical atherosclerosis. Prospective study included runners of both sexes (n = 52) and age and gender matched controls (n = 57), without classical cardiovascular risk factors. Ventricular hypertrophy was quantified by echocardiography by linear method and carotid in...

This study was conducted to determine the anthropometric measurements and body composition of selected national athletes. A total of 84 male athletes from 10 different types of sports and 24 female athletes from 5 types of sports were studied. The height and body weight of subjects were measured using the SEGA weighing balance with height attachment. Skinfold thickness measurements were taken u...

BACKGROUND Female athletes have increased risk of anterior cruciate ligament rupture after the onset of puberty. HYPOTHESES Male athletes would demonstrate a longitudinal increase in vertical jump height compared with female athletes. There would be longitudinal gender differences in ground-reaction forces and loading rates. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Sixteen...

[Purpose] This study aimed 1) to assess whether a prediction model for whole body skeletal muscle mass that is based on a sedentary population is applicable to young male athletes, and 2) to develop a new skeletal muscle mass prediction model for young male athletes. [Subjects and Methods] The skeletal muscle mass of 61 male athletes was measured using magnetic resonance imaging (MRI) and estim...

The primary objective of this study was to determine the differences between male and female athletes competing in the 400m running event, in the parameters for the assessment of not only aerobic and anaerobic energy capacity but also other physiological parameters. Trained 400m (14 male and 14 female) track athletes volunteered to take part in this study. All subjects performed an incremental ...

BACKGROUND Female athletes are at significantly greater risk of anterior cruciate ligament (ACL) injury than male athletes in the same high-risk sports. Decreased trunk (core) neuromuscular control may compromise dynamic knee stability. HYPOTHESES (1) Increased trunk displacement after sudden force release would be associated with increased knee injury risk; (2) coronal (lateral), not sagitta...

BACKGROUND Research on the acute effects of a concussion among lacrosse players is limited, and postconcussion patterns between male and female athletes have yet to be clearly established. Differences in the style of play and protective gear worn among male and female lacrosse players potentially confound a direct comparison of sex-based differences in this population. PURPOSE To explore sex-...

background: severe and prolonged physical training is associated with morphological and physiological cardiac changes, often termed as the “athlete’s heart”. echocardiographic features peculiar to elite iranian athletes have not been previously described. the aim was to examine the echocardiographic characteristics of highly trained iranian athletes involved in three different sports.   methods...

OBJECTIVE The objectives of the study were to examine the prevalence of anorexia nervosa (AN), bulimia nervosa (BN), anorexia athletica (AA), and eating disorders not otherwise specified (ED-NOS) in both male and female Norwegian elite athletes and a representative sample from the general Norwegian population. DESIGN A 2-step study including self-reported questionnaire and clinical interview....

BACKGROUND The combined positioning of the trunk and knee in the coronal and sagittal planes during non-contact anterior cruciate ligament (ACL) injury has not been previously reported. HYPOTHESIS During ACL injury female athletes demonstrate greater lateral trunk and knee abduction angles than ACL-injured male athletes and uninjured female athletes. DESIGN Cross-section control-cohort desi...
