PG ingested lactose powder. Participants...

Iron (Fe) is one of the most widely studied trace mineral elements. Fe metabolism and homeostasis could be altered by physical training. The aim this study was to analyze influence long-term training on serum, plasma, urine (extracellular), erythrocyte platelet (intracellular) concentrations. Forty men from same geographical area divided into a group (TG; n = 20; 18.15 ± 0.27 years) control (CG; 19.25 0.39 participated in study. TG composed soccer players highest youth category. CG consisted...

Carbohydrate intake is a commonly used strategy in sports, and supplementation for triathletes includes pre-competition, intra-competition, post-competition intake. The consumption of fructose–glucose improves intestinal transit gastric emptying. main purpose this study was to analyse the effect intra-session carbohydrate training super-sprint modality. Eleven adolescent (boys, n = 9, 14.6 years; girls, 2, 15.2 years) participated crossover, randomised, blind on with 45 g carbohydrates...

The aim of the present study was to evaluate possible effect a period 6 months aerobic physical training on serum and urinary concentrations arsenic (As), beryllium (Be), cadmium (Cd) lead (Pb), potentially toxic minerals. Twenty-four well-trained, long distance runners (AG), were recruited at start their period. They had been performing regularly for previous 2 years, recording an average volume 120 km per week rigorous exercise aimed high-level competitions (1500 5000 m race modalities)....

Molybdenum (Mo) and zinc (Zn) play important roles in the process of adaptation to physical training. The aims present study were: (i) analyze differences extracellular (plasma urine) intracellular (erythrocytes platelets) Mo Zn concentrations between sexes (ii) relate with biomarkers muscle damage mass. involved 138 semi-professional soccer players divided according sex: male (n = 68) female 70). were determined by inductively coupled plasma mass spectrometry.

Heat exposure provokes stress on the human body. If it remains constant, leads to adaptations such as heat acclimation. This study aims observe evolution of heart rate (HR), core temperature (Tcore), and skin (Tskin) in an intervallic program extreme heat. Twenty-nine healthy male volunteers were divided into a control group (CG; n = 14) experimental (EG; 15). EG experienced nine sessions (S) high temperatures (100 ± 2 °C), whereas CG was exposed ambient (22 °C). HR, Tskin, Tcore monitored...

It has been suggested that heat exposure prior to exercise could induce changes in anaerobic exercise. Therefore, the purpose of this study was observe effects high temperature an test. Twenty-one men (age: 19.76 ± 1.22 years; height: 1.69 0.12 m; weight: 67.89 11.78 kg) voluntarily participated investigation. All them performed two Wingate tests, vertical jump and macronutrient intake control. On first day, test under normal environmental conditions. second it a similar way, but with...

Aluminum (Al) is one of the most abundant trace mineral elements in earth’s crust. Al considered a potent neurotoxicant. Physical exercise could cause modifications some elements. On other hand, there be sex differences exposure and deposits toxic The aim present study was to compare seasonal extracellular intracellular concentrations football players. involved 22 male 24 female players from fifth second national category, respectively. Three assessments were carried out during season...

Background: Caffeine is an ergogenic aid that still needs to be investigated in female sports per-formance. Methods: Eight semi-professional volleyball (Heigth=1.63±0.08 m; Weigth= 66.67 ± 4,.74 kg) players voluntarily participated this study. A randomised crossover design was carried out. Players went through the caffeine and placebo condition. In condi-tion, participants consumed 5 mg/kg of caffeine. The evaluations were performed over two weeks training. both conditions, countermovement...
