BACKGROUND: Tart Montmorency cherries contain high concentrations of phytochemicals and anthocyanins, which have recently been linked to improved athletic recovery and subsequent performance. To date however, previous work reporting promising results has focused on land-based endurance sports, with any potential benefits to team sports remaining unknown. As such, this investigation set-out to examine the effect of supplemental tart cherry juice (CJ) on recovery and next day athletic performance in highly-trained water-based team sport athletes over seven days...

After 30 years of age physical capacity decreases with increasing age by 5-20% per decade. High physical activity in daily life as well as exercise training of endurance, strength, coordination and mobility can delay the functional and anatomical loss of muscle, bone, cartilage and connective tissue by more than 10 years. In recent years, numerous concepts have scientifically been proven in the exercise therapy of internal diseases; therefore, similar to drug treatment, cellular mechanisms of exercise training adaptation are known in detail...

BACKGROUND: While it is well established that dietary nitrate reduces the metabolic cost of exercise, recent evidence suggests this effect is maintained 24 h following the final nitrate dose when plasma nitrite levels have returned to baseline. In addition, acute dietary nitrate was recently reported to enhance peak power production. Our purpose was to examine whether chronic dietary nitrate supplementation enhanced peak power 24 h following the final dose and if this impacted performance in a heavily power-dependent sport...

Healthcare professionals frequently advise patients with simple infective illness to drink more fluids. Here, a 59-year-old woman with a urinary tract infection followed such advice resulting in hospital admission with symptomatic acute hyponatraemia. Water intoxication is well recognised as a cause of symptomatic hyponatraemia in endurance sports, MDMA use and psychogenic polydipsia. It has rarely been described outside of these circumstances. With normal renal function, it is difficult to overwhelm the excretory capacity for water...

INTRODUCTION: The impact of a history of competitive sports on later use of alcohol and occurrence of alcohol-related diseases is poorly known. We investigated how a history of elite level sports was associated with alcohol consumption in middle-age and with alcohol-related morbidity and mortality. METHODS: Occurrence of alcohol-related diseases and deaths were followed using national registers from 1970 to 2008 among Finnish male former elite athletes (n=2202) and matched controls (n=1403) alive in 1970 (mean age 45...

BACKGROUND: In recent years, athletes have ventured into ultra-endurance and adventure racing events, which tests their ability to race, navigate, and survive. These events often require race participants to carry some form of load, to bear equipment for navigation and survival purposes. Previous studies have reported specific alterations in biomechanics when running with load which potentially influence running performance and injury risk. We hypothesize that a biomechanically informed neuromuscular training program would optimize running mechanics during load carriage to a greater extent than a generic strength training program...

The purpose of this study was to perform a construct validity assessment of Kendzierski's exercise self-schema theory questionnaire using objective measures of health-related physical fitness. This study tested the hypothesis that individuals with an exercise self-schema would possess significantly greater physical fitness than those who did not across three domains of health-related physical fitness: Body composition, cardiovascular fitness, and upper-body muscular endurance. Undergraduate student participants from one private university on the west coast of the United States completed informed consent forms and the exercise self-schema questionnaire within a classroom setting or at an on-campus outside tabling session...

PURPOSE: Caffeine-containing energy drinks (EDs) are currently used as ergogenic aids to improve physical performance in a wide variety of sport disciplines. However, the outcomes of previous investigations on this topic are inconclusive due to methodological differences, especially, in the dosage of the active ingredients and the test used to assess performance. METHODS: We performed a systematic review and meta-analysis of published studies to evaluate the effects of acute ED intake on physical performance...

Despite some advances, it remains largely unknown how the millions of variations in the human genome influence athletic performance (especially in endurance events), and no single genetic test can really predict sports talent. However, there is experimental evidence from animal research that selecting for even a simple characteristic such as running ability can produce comparatively large and rapid changes in performance. That such selection has not been specifically documented in humans is more evidence of the limits of physiology-archeology than of the unlikelihood of selection for physical abilities...
