OBJECTIVES The goal of this study was to perform a meta-analysis of the published literature to investigate the relationship of high levels of exercise training to left atrial (LA) size. BACKGROUND The "athlete's heart" is a series of cardiac adaptations to systematic exercise training and may include LA enlargement. METHODS We conducted a systematic review of English-language studies in ME...

OBJECTIVE To compare bone mineral density (BMD), investigate factors associated with BMD, and examine the prevalence of low BMD in athletes and non-athletic controls. METHODS The study included a questionnaire (part I), measurement of BMD (part II), and a clinical interview (part III). All Norwegian female athletes on national teams (n = 938) and an aged matched random sample of non-athletic ...

Limited data are available on the female athlete triad (Triad) in athletes from minority groups. We explored subclinical and clinical Triad components amongst adolescent elite Kenyan athletes (n = 61) and non-athletes (n = 49). Participants completed demographic, health, sport and menstrual history questionnaires as well as a 5-day weighed dietary record and exercise log to calculate energy ava...

Depression affects an estimated 6.7% of today's adult population in a 12-month period. The prevalence rates for certain age groups, such as young adults and older adults, are higher. There are approximately 400,000 National Collegiate Athletic Association student athletes competing each year and 5 to 7 million high school student athletes involved in competitive interscholastic sports. Given su...

Adequate energy intake in adolescent athletes is considered important. Total energy expenditure (TEE) can be calculated from resting energy expenditure (REE) and physical activity level (PAL). However, validated PAL recommendations are available for adult athletes only. Purpose was to comprise physical activity data in adolescent athletes and to establish PAL recommendations for this population...

BACKGROUND Prevalence rates of invalid baseline scores on computerized neurocognitive assessments for high school, collegiate, and professional athletes have been published in the literature. At present, there is limited research on the prevalence of invalid baseline scores in pre-high school athletes. HYPOTHESIS Pre-high school athletes assessed with baseline neurocognitive tests would show ...

NITRATE RICH BEETROOT JUICE has become a popular sports supplement because of its proposed ergogenic properties. The effects of dietary nitrate supplementation on exercise performance have been attributed to its capacity to increase nitric oxide (NO) bioavailability. NO modulates many processes that are essential to exercise performance, such as regulation of blood flow, muscle contractility, m...

OBJECTIVE To measure working memory capacity among a cohort of collegiate athletes and to compare results between athletes competing in head-contact-prone sports with those not subject to repeated head contacts. A secondary objective was to determine the effect of sport-related concussion on working memory capacity. DESIGN Ambidirectional cohort study. SETTING Athletics department at an Ame...
