“…1 Several researches have also focused on soy and whey protein in athletes diets. For example, Kalman et al 4 studied the effects of soy-and milk-based proteins on circulating androgens and changes associated with exercise-induced body composition. For 12 weeks, 20 subjects took 50 g of one of four protein sources (soy isolate; soy concentrate; soy isolate and whey blend; or whey blend only)/day during their participation in a resistance training program.…”

It is widely known that athletes used to rely on training and good nutrition to provide maximum results. But now to maintain a competitive edge, athletes are switching to nutraceuticals. They are dietary supplements that provide health benefits. Nutraceuticals and dietary supplements are now commonly used to enhance and improve the health and performance of athletes. This has triggered the sale of nutraceuticals in the market and stores and gyms are selling hundreds of different supplements. These nutritional supplements usually claim to improve strength, performance and stamina, help build lean muscle, and help to burn excess fat. There are many health and nutritional supplements available in the market for the athletes. It is a difficult choice to choose the suitable and appropriate nutraceutical for oneself. The present article will introduce the athlete to a variety of different nutritional health supplements available in the market including fat burners, conjugated linoleic acid (CLA), numerous essential fatty acids (EFAs), creatine, whey proteins, glutamine, Tribulusterrestris, beta-hydroxy beta-methylbutyrate (HMB), methoxyIsoflavone, and Cordyceps.

“…En estas primeras 2 horas la ingesta de HC permite una resín-tesis del glucógeno muscular 35 , debido a que aumentan los valores de insulina 84,85 , y los procesos anabólicos se dan con mayor e cacia y mejora el estado hormonal tras el ejercicio 3,14,49 . Sin embargo, diversos estudios postulan un consumo de HC y proteínas antes y durante el entrenamiento para disminuir el catabolismo proteico y prescindir posteriormente de un suplemento de proteínas en las fases de recuperación 86 .…”

Uno de los efectos más importantes del entrenamiento de la fuerza es el aumento de la hipertrofia muscular. Para compensar sus limitaciones genéticas, los deportistas deben tratar de optimizar los recursos dietético-nutricionales. El objetivo de la presente revisión es analizar la evidencia científica del aporte proteico del deportista según las diferentes modalidades deportivas. Dependiendo del gasto y el aporte energéticos del deportista, el aporte total de proteínas de la ingesta energética diaria suele suponer un 10-15%; sin embargo, es preferible calcular la cantidad proteica necesaria por kg de peso corporal de cada individuo en concreto y según la disciplina deportiva. En este sentido, se estima que para mantener la masa muscular los deportistas deben consumir 1,2-1,8 g de proteínas/kg/día, y para aumentarla (0,5 kg masa muscular/semana) deben mantener una ingesta proteica de 1,6-1,8 g de proteína/kg/día, con un aumento de 400-500 kcal en su dieta habitual, entendiendo que estas necesidades variarán según la modalidad deportiva, la destrucción muscular generada, la masa muscular del atleta y los depósitos de glucógeno. Es importante señalar que los depósitos de glucógeno muscular y hepático vacíos aumentarían las necesidades proteicas para mantener la masa muscular. Un exceso de ingesta de proteínas (> 2 g/kg/día) con las reservas de glucógeno agotadas podría causar un aumento de la concentración de cuerpos cetónicos y urea, y producir, entre otros, deshidratación precoz del deportista.
