Effect of high-fat diets on body composition, lipid metabolism and insulin sensitivity, and the role of exercise on these parameters
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Coelho,D.F.; Pereira-Lancha,L.O.; Chaves,D.S.; Diwan,D.; Ferraz,R.; Campos-Ferraz,P.L.; Poortmans,J.R.; Lancha Junior,A.H.
Dietary fat composition can interfere in the development of obesity due to the specific roles of some fatty acids that have different metabolic activities, which can alter both fat oxidation and deposition rates, resulting in changes in body weight and/or composition. High-fat diets in general are associated with hyperphagia, but the type of dietary fat seems to be more important since saturated fats are linked to a positive fat balance and omental adipose tissue accumulation when compared to other types of fat, while polyunsaturated fats, omega-3 and omega-6, seem to increase energy expenditure and decrease energy intake by specific mechanisms involving hormone-sensitive lipase, activation of peroxisome proliferator-activated receptor α (PPARα) and...

Protein turnover, amino acid requirements and recommendations for athletes and active populations
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Poortmans,J.R.; Carpentier,A.; Pereira-Lancha,L.O.; Lancha Jr.,A.
Skeletal muscle is the major deposit of protein molecules. As for any cell or tissue, total muscle protein reflects a dynamic turnover between net protein synthesis and degradation. Noninvasive and invasive techniques have been applied to determine amino acid catabolism and muscle protein building at rest, during exercise and during the recovery period after a single experiment or training sessions. Stable isotopic tracers (13C-lysine, 15N-glycine, ²H5-phenylalanine) and arteriovenous differences have been used in studies of skeletal muscle and collagen tissues under resting and exercise conditions. There are different fractional synthesis rates in skeletal muscle and tendon tissues, but there is no major difference between collagen and myofibrillar...
