BACKGROUND Our purpose was to determine the relationship between energy intake, energy availability, dietary fat and lower extremity injury in adult female runners. We hypothesized that runners who develop overuse running-related injuries have lower energy intakes, lower energy availability and lower fat intake compared to non-injured runners. METHODS Eighty-six female subjects, running a min...

conclusions maximal and supra-maximal races induce a significant increase in lipid peroxidation and cause non-negligible inflammation and muscle damage. these effects were relatively related to the physical exercise type and the sportive specialty. results a significant increase in malondialdehyde (mda) concentrations was observed in ss and mdr after the vameval test and in ldr after the limite...

BACKGROUND Exercise has been shown to improve many health outcomes and well-being of people of all ages. Long-term studies in older adults are needed to confirm disability and survival benefits of exercise. METHODS Annual self-administered questionnaires were sent to 538 members of a nationwide running club and 423 healthy controls from northern California who were 50 years and older beginnin...

BACKGROUND Studies have shown cardiac changes induced by intense and regular physical activity. The purpose of this study was to evaluate cardiac structures and function in soccer players, cyclists and long-distance runners, and compare them with non-athlete controls. MATERIAL AND METHODS Cardiac structural, systolic, and diastolic function parameters in 53 athletes and 36 non-athlete control...

Previous research has proposed that a lack of variability in lower extremity coupling during running is associated with pathology. The purpose of the study was to evaluate lower extremity coupling variability in runners with and without a history of iliotibial band syndrome (ITBS) during an exhaustive run. Sixteen runners ran to voluntary exhaustion on a motorized treadmill while a motion captu...

BACKGROUND Marathon running has surged in popularity; it is generally believed to be healthy, but may be associated with medical risks. Over the past decade, we observed 8 ultramarathon runners with malignant melanoma. UV exposure, immunosuppression due to long-term intensive exercise, or both have been discussed as potential triggers in these patients. To further evaluate risk factors for mali...

BACKGROUND Long-term physical exercise leads to left ventricular morphological adaptations, which vary with the kind of sport and the intensity and extent of the training. Although the echocardiographic changes related to exercise in athletes participating in various sports have been well described, changes associated with football players have been less well documented. The aim of this study w...

In this study we present the morphological characteristics of 54 Croatian national level track-and-field athletes. 21 anthropometric body measures were taken on a sample of 15 sprinters (S), 16 endurance sprinters (S4), 10 middle-distance runners (MD) and 13 long-distance runners (LD). Body fat percentage, body mass index and somatotype were also calculated. Canonical discriminative analysis sh...
