Durante mucho tiempo no había principios uniformes para la Atribución de nombres a los antibióticos https://antibioticos-wiki.es . Más a menudo se les llama por el nombre genérico o especie del producto, con menos frecuencia-de acuerdo con la estructura química. Algunos antibióticos se nombran de acuerdo con el lugar donde se asignó el producto.

Abstract Background – Previous works assumed that the BCAA (branched- chain amino acids), L- arginine and CLA
(conjugated linoleic acid) supplementation may affect rest energy expenditure (REE) and the decrease of fat
This study aims at testing whether these substances can actually increase rest energy expenditure and improve body composition.
Methods and results – 25 healthy volunteers, aged 29,8 ± 7,4 years have been tested. (twenty-two men and three women among athletes, sportsmen/sportswomen, sports-practicing subjects and inactive subjects: in general all active). All subjects started a normocaloric and balanced diet 1 week before the first calorimetry test, keeping it on till the 2° test. They began the supplementation with two products available in the market: X- Treme CLA and X-Treme NOX, (Inkospor Italy Ltd). One, CLA, contains conjugated linoleic acid and the other, NOX, contains branched-chain amino acids, arginine, green tea extracts, caffeine and vitamin C. Volunteers have been given the above mentioned integrators for two weeks. Rest energy expenditure (REE kcal/day), free mass rate (FFM %), fat mass rate (FM %), body weight (Kg) and BMI (Kg/m2), have been monitored before and after the two week cycle. Results - The supplementation intake has led to significant results as it follows: (*p<0,005) (-1,24%) body weight, BMI (-1,25%), FM (-4,28%) and FFM(+1,07%). The REE hasn't led to significant results (p=0,0179) despite a 10,9 % increase. Beyond the results we need to highlight that six subjects were excluded from the REE average as the tests were not reliable for different reasons. Discussion - The results about REE and slight variations on body composition due to the two supplements intake are consistent with this study. We are convinced that the action of the ingredients taken singularly is not clear/evident. Even if the calorific increase of rest energy expenditure (REE) is slight, we think that it can help subjects control their weight. The combination between balanced diet and adequate physical activity may benefit the fat mass decrease and the improvement of body composition in sportsmen and inactive subjects. Even though the results are encouraging, medium- and long- term studies on these data are required in particular on rest energy expenditure and its variables affecting calorimetry. References:
