Filter by:This project comes forward with investigations regarding the use of yerba mate infusion in sports performance, providing new knowledge about the effects of its consumption on the performance of trained individuals, thus elucidating new mechanisms of ergogenic action of the plant in characteristics of dietary management indicated for trained individuals, besides investigating on the action of the bioactive compounds of the plant in the metabolism and performance of athletes and the physiological aspects.
The aim of this study to increase understanding of physiological and functional perturbations following a continuum of exercise stressors.
Creatine (methyl-d3) dilution (D3-creatine) is a novel technique for the estimation of muscle mass. The method uses a dose of deuterium-labelled creatine to determine total skeletal muscle mass via estimation of total body creatine pool size.The aim of this study is to compare estimates of total body skeletal muscle mass by D3-creatine dilution method and whole body Magnetic Resonance Imaging (MRI) in an athletic population.
This study is designed to investigate whether protein supplementation can improve recovery of muscle function following a strenuous combination of both endurance and resistance exercise. It will specifically investigate the effect of protein supplementation on the recovery of strength, power and endurance exercise performance, along with measures of damage and inflammation of the muscle.
Abnormal opioid system have been identified in addictive behavior and activity of the opioid system has also shown a strong link with the nutritional balance. A significant increase in endorphin levels was noticed after exercise, proportional to the duration and intensity of this activity. One brain imaging study showed an increase in opioid activity in athletes after endurance training. However , a decrease in opioid tone related to receptor desensitization in the brain has been raised in the sport and it is possible to feel like , the subject must perform physical exercise more frequently . Consequently, in order to deepen the hypothesis of addiction in high-level sport , the brain opioid activity should be assessed pre- training compared to a group of sedentary control subjects . Preliminary results of a previous study the investigators are conducting on anorexia nervosa (AN ) show abnormalities that appear to be involved in self addiction anorexia nervosa and the regulation of gonadal function. However, the relation of cause and effect between these anomalies and undernutrition remains to be determined . Given the addictive component in the endurance sport and the variability of the nutritional status of its practitioners , evaluation of brain activity in these subjects could provide additional answers.
