We aimed to evaluate whether an intervention program emphasizing in increased fluid intake can improve exercise performance in children exercising in the heat. Ninety-two young athletes participated in the study (age: 13.8 ± 0.4 years, weight: 54.9 ± 1.5 kg). Thirty-one (boys: 13, girls: 18) children served as the control group (CON) and 61 (boys: 30,(More)
UNLABELLED It has been suggested that mouth rinse and/or ingestion of fluids during exercise may have a beneficial effect on performance. However, the existing results are controversial. PURPOSE We hypothesized that pharyngeal receptor activation through ingestion of a small amount of water could enhance performance better than mouth rinse in dehydrated(More)
CONTEXT Hydration has been shown to be an important factor in performance; however, the effects of mild dehydration during intense cycling are not clear. OBJECTIVE To determine the influence of mild dehydration on cycling performance during an outdoor climbing trial in the heat (ambient temperature = 29.0°C ± 2.2°C). DESIGN Crossover study. SETTING(More)
BACKGROUND To investigate the association between gestational weight gain, maternal age and lifestyle habits (e.g., physical activity, smoking, and alcohol consumption) during pregnancy, with Body Mass Index of the offspring at the age of 8. METHODS Α random sample of 5,125 children was extracted from a national database and matched with their mothers.(More)
CONTEXT Sodium replacement during prolonged exercise in the heat may be critically important to maintaining fluid and electrolyte balance and muscle contractility. OBJECTIVE To examine the effectiveness of sodium-containing sports drinks in preventing hyponatremia and muscle cramping during prolonged exercise in the heat. DESIGN Randomized crossover(More)
Although there are many studies demonstrating a high percentage of adult athletes who start exercise in suboptimal hydration state, limited data concerning hydration levels in athletic youth exist. The purpose of this study was to identify the hydration status of elite young athletes of different sports, during a typical day of training. Fifty-nine young(More)
UNLABELLED There is a lack of studies concerning hydration status of young athletes exercising in the heat. PURPOSE To assess preexercise hydration status in young soccer players during a summer sports camp and to evaluate body- water balance after soccer training sessions. METHODS Initial hydration status was assessed in 107 young male soccer players(More)
AIM Urine color (UC) is a practical tool for hydration assessment. The technique has been validated in adults, but has not been tested in children. PURPOSE The purpose of the study was to test the validity of the urine color scale in young, healthy boys and girls, as a marker of urine concentration, investigate its diagnostic ability of detecting(More)
We studied the association of physical activity and adherence to the Mediterranean diet, in total antioxidant capacity (TAC). A random sample of 1514 men and 1528 women was selected from Attica region. Physical activity was assessed with a translated version of the validated "International Physical Activity Questionnaire" (iPAQ), and dietary intake through(More)
BACKGROUND/OBJECTIVES The aims of the study were as follows: (1) examine fluid intake and urinary hydration markers of children in Greece, (2) determine the calculated relative risk of hypohydration in children who did not meet the recommendations for daily water intake provided by the Institute of Medicine and the European Food Safety Authority compared(More)
